kn-title=Managing Persistent Pupillary Membranes With Surgery or Medication: A Report of Three Cases
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The persistent pupillary membrane, as a congenital anomaly, is a remnant of a network of feeding blood vessels for the lens of the eye, called tunica vasculosa lentis. This study reports three patients with persistent pupillary membrane in both eyes who presented in different situations and were managed differently to achieve better vision. The first child (Case 1) who had been seen initially at the age of two years complained of severe photophobia even though he had good visual acuity, and hence, he and his family chose surgical resection of the pupillary membrane in both eyes at the age of six years just before the admission to an elementary school. He did not develop any surgical complications, such as cataract and glaucoma, and maintained the visual acuity in decimals of 1.2 in both eyes at the age of 17 years.<br>
The second child (Case 2), who was seen first at the age of one month, had persistent pupillary membranes in both eyes, together with Peters' anomaly in the left eye. The iris process adhesion to the corneal inner surface was visualized later by optical coherence tomography. She wore full-correction glasses and obtained the visual acuity of 0.7 in the right eye, so she had no problem studying at an elementary school. She used topical 1% atropine once a week in both eyes to maintain pupillary dilation and also used 0.5% timolol and 1% brinzolamide as pressure-lowering eye drops in the left eye with Peters' anomaly.<br>
The third patient (Case 3) with persistent pupillary membranes in both eyes complained of vision problems for the first time at the age of 49 years when she developed cataract. Surgical resection of the pupillary membrane was done in the initial phase of cataract surgery with intraocular lens implantation in both eyes. At surgical resection of the pupillary membrane, a safe and efficient way was to cut the root of the pupillary membrane on the iris surface with scissors, and then the isolated tissues of the pupillary membrane were pulled out with forceps from the side port at the corneal limbus. Pathological examinations of the excised tissues showed blood vessels with red blood cells in the lumen. In such a rare congenital disease as the persistent pupillary membrane, a case-based approach to choose a better option in different conditions from individual to individual is still required to have a better vision in learning at school and in daily working life.

kn-title=Nephronophthisis and Retinitis Pigmentosa (Senior-Loken Syndrome) After Living-Donor Kidney Transplantation: Twelve-Year Follow-Up in a Young Woman
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Senior-Loken syndrome is a hereditary ciliopathy with recessive trait that manifests as nephronophthisis and retinitis pigmentosa. This report described an 18-year-old woman who was referred to a University Hospital to set up a treatment plan for chronic renal failure of an unknown cause. She had experienced nocturnal polyurea from the age of 12 years and was found to have an elevated level of serum creatinine at 3 mg/dL at the age of 15 years. She underwent renal biopsy at a hometown regional hospital which showed global glomerulosclerosis in six of the 13 glomeruli examined, renal tubular dilation in irregular shape, and marked interstitial fibrosis with lymphocytic infiltration. At the age of 19 years, she received a living-donor kidney transplant from her 46-year-old father as a preemptive therapy. At surgery, biopsy of the father’s donor kidney showed two glomeruli with global sclerosis out of 24 glomeruli examined, in association with minimal interstitial fibrosis and lymphocytic infiltration. She began to have extended-release tacrolimus 4 mg daily and mycophenolate mofetil 1,000 mg daily. According to the standard protocol, she underwent biopsy of the transplanted donor kidney to reveal interstitial fibrosis and lymphocytic infiltration, in addition to no sign of rejection and no glomerular deposition of immunoglobulins and complements, both 4 weeks and 14 months after the kidney transplantation. At the age of 23 years, 4 years after the kidney transplantation, she was, for the first time, diagnosed retinitis pigmentosa, and hence, Senior-Loken syndrome. She was followed up in the stable condition with basal doses of tacrolimus 5 mg daily, mycophenolate mofetil 1,000 mg daily, and prednisolone 5 mg daily up until now in 12 years after the kidney transplantation. The interstitial fibrosis with lymphocytic infiltration in the donor kidney might be a milder presentation of the disease with recessive inheritance.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We perform optical measurements and numerical simulations of guided phonon propagation in novel topological phononic crystal structures at ultrahigh frequencies. The structures support valley-polarized states that exhibit an energy vortex nature and propagate with high efficiency at domain boundaries because backscattering is suppressed due to conservation of time reversal symmetry. We extract frequency- and time-resolved spatial mode patterns and k-space images, together with dispersion relations. We investigate the conditions required for robust propagation along interfaces and thereby observe very high efficiency waveguiding.

kn-title=Demonstration of enhanced Raman scattering in high-Q silicon nanocavities operating below the silicon band-gap wavelength
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We experimentally determined the quality factor (Q) and the intensity of the Raman scattered light for different silicon photonic-crystal nanocavities operating at wavelengths shorter than the silicon band-gap wavelength. Despite the relatively large absorption of silicon in this wavelength region, we observed Q values greater than 10,000 for cavities with a resonance wavelength of 1.05 mu m, and Q values greater than 30,000 for cavities with a resonance wavelength of 1.10 mu m. Additionally, we measured the Raman scattering spectra of cavities with resonance wavelengths of 1.10 mu m and 1.21 mu m. On average, the generation efficiency of the Raman scattered light in a 1.10-mu m nanocavity is 6.5 times higher than that in a 1.21-mu m nanocavity. These findings suggest that silicon nanocavities operating below the silicon band-gap wavelength could be useful in the development of silicon-based light sources.

kn-title=Length Estimation of Pneumatic Artificial Muscle with Optical Fiber Sensor Using Machine Learning
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A McKibben artificial muscle is a soft actuator driven by air pressure, characterized by its flexibility, lightweight design, and high power-to-weight ratio. We have developed a smart artificial muscle that is capable of sensing its motion. To enable this sensing function, an optical fiber was integrated into the sleeve consisting of multiple fibers and serving as a component of the McKibben artificial muscle. By measuring the macrobending loss of the optical fiber, the length of the smart artificial muscle is expected to be estimated. However, experimental results indicated that the sensor's characteristics depend not only on the length but also on the load and the applied air pressure. This dependency arises because the stress applied to the optical fiber increases, causing microbending loss. In this study, we employed a machine learning model, primarily composed of Long Short-Term Memory (LSTM) neural networks, to estimate the length of the smart artificial muscle. The experimental results demonstrate that the length estimation obtained through machine learning exhibits a smaller error. This suggests that machine learning is a feasible approach to enhancing the length measurement accuracy of the smart artificial muscle.

kn-title=A Rare Case of Compression Neuritis due to Intraorbital Arteriovenous Fistula (IOAVF) Mimicking Retrobulbar Optic Neuritis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Intraorbital arteriovenous fistulas (IOAVFs) are rare vascular abnormalities. We describe a case of an IOAVF featuring a direct shunt between the accessory meningeal artery and the superior ophthalmic artery. A 55-year-old woman presented with a 1-month history of visual impairment in her right eye, and magnetic resonance imaging (MRI) revealed optic neuritis-like findings. Steroid pulse therapy temporarily resolved visual impairment. However, 1 month later, she experienced decreased visual acuity, ocular conjunctival hyperemia, edema, and a pulsatile murmur. Contrast-enhanced MRI and digital subtraction angiography revealed compression optic neuropathy due to an IOAVF. Following successful treatment with transarterial embolization, her symptoms disappeared.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=With the rapid advancement of information technology, there is a pressing need to develop ultracompact and energy-efficient thin-film-based electro-optic (EO) devices. A high EO coefficient in ferroelectric materials is crucial. However, substrate clamping can positively or negatively influence various physical properties, including the EO response of these films, thus complicating the development of next-generation thin-film-based devices. This study demonstrates that reversible dynamic domain motion, achieved through substrate clamping, significantly enhances the EO coefficient in epitaxial ferroelectric rhombohedral Pb(Zr, Ti)O3 thin films, where the (111) and (⁠ 111⁠) domains coexist with distinct optical axes. In principle, this approach can be applied to different film-substrate systems, thereby contributing to the advancement of sophisticated EO devices based on ferroelectrics.

kn-title=Bright Quantum-Grade Fluorescent Nanodiamonds
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Optically accessible spin-active nanomaterials are promising as quantum nanosensors for probing biological samples. However, achieving bioimaging-level brightness and high-quality spin properties for these materials is challenging and hinders their application in quantum biosensing. Here, we demonstrate bright fluorescent nanodiamonds (NDs) containing 0.6–1.3-ppm negatively charged nitrogen-vacancy (NV) centers by spin-environment engineering via enriching spin-less 12C-carbon isotopes and reducing substitutional nitrogen spin impurities. The NDs, readily introduced into cultured cells, exhibited improved optically detected magnetic resonance (ODMR) spectra; peak splitting (E) was reduced by 2–3 MHz, and microwave excitation power required was 20 times lower to achieve a 3% ODMR contrast, comparable to that of conventional type-Ib NDs. They show average spin-relaxation times of T1 = 0.68 ms and T2 = 3.2 μs (1.6 ms and 5.4 μs maximum) that were 5- and 11-fold longer than those of type-Ib, respectively. Additionally, the extended T2 relaxation times of these NDs enable shot-noise-limited temperature measurements with a sensitivity of approximately 0.28K/√Hz. The combination of bulk-like NV spin properties and enhanced fluorescence significantly improves the sensitivity of ND-based quantum sensors for biological applications.

en-subtitle=

kn-abstract=In this article, an approach used for the inspection tasks in the WRS2020 Plant Disaster Prevention Challenge is explained. The tasks were categorized into three categories: reading pressure gauges, inspecting rust on a tank, and inspecting cracks in a tank. For reading pressure gauges, the “you only look once” algorithm was used to focus on a specific pressure gauge and check the pressure gauge range strings on the gauge using optical character recognition algorithm. Finally, a previously learned classifier was used to read the values shown in the gauge. For rust inspection, image processes were used to focus on a target plate that may be rusted for rust detection. In particular, it was necessary to report the rust area and distribution type. Thus, the pixel ratio and grouping of rust were used to count the rust. The approach for crack inspection was similar to that for rust. The target plate was focused on first, and then the length of the crack was measured using image processing. Its width was not measured but was calculated using the crack area and length. For each system developed to approach each task, the results of the preliminary experiment and those of WRS2020 are shown. Finally, the approaches are summarized, and planned future work is discussed.

kn-title=Terpolymerization reactions of epoxides, CO2, and the third monomers toward sustainable CO2-based polymers with controllable chemical and physical properties
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Carbon dioxide (CO2) serves as a cheap, abundant, and renewable C1 building block for the synthesis of organic compounds and polymers. Selective and efficient CO2 fixation processes are still challenging because of the kinetic and thermodynamic stability of CO2. Among various CO2 fixation processes, the ring-opening copolymerization (ROCOP) of epoxides and CO2 gives aliphatic polycarbonates with high atom economy, although the chemical and physical properties of the resulting polycarbonates are not necessarily satisfactory. Introducing the third monomers into this ROCOP system provides new terpolymers, and the thermal, optical, mechanical or degradation properties can be added or tuned by incorporating new polymer backbones derived from the third monomers at the expense of the CO2 content. Here we review the terpolymerization reactions of epoxides, CO2, and the third monomers such as cyclic anhydrides, lactones, lactides, heteroallenes, and olefins. The development of catalysts and the control of the polymer structures are described together with the chemical and physical properties of the resulting polymers.

kn-title=Petrological characterization for material provenance of haniwa earthenware from mounded tombs in the Kibi region, Japan
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=To determine the provenance of the materials used in the production of haniwa earthenware unearthed from mounded tombs (kofun) in the Kibi region (modern Okayama Prefecture) during the Kofun period (late 3rd – 6th century CE) of Japan, we carried out petrological analyses of haniwa sherds, including optical microscopy, X-ray diffractometry, X-ray fluorescence spectroscopy, and electron-probe analysis. The 25 haniwa sherds analyzed from 12 representative mounded tombs are composed of mineral and rock inclusions with variable grain size set in a clay matrix. The dominant inclusions are quartz, K-feldspar, and plagioclase, associated with minor amounts of amphibole, volcanic glass, and granitic rocks in all the haniwa sherds, and small amounts of hornfels, quartz rock, and accessory minerals, including mica, ilmenite, and chromite, in some of the sherds. Amphibole and plagioclase have compositional variations indicative of the mixing of tephra and granitic components. The compositions of volcanic glass inclusions are similar to those of the Aira-Tanzawa and Kikai-Akahoya tephras widely distributed in southwestern Japan. Bulk chemical compositions show magmatic differentiation trends, which are variable between individual tombs. From these results, it is concluded that the paste materials of haniwa in the Kibi region were commonly derived from weathered granitic rocks mixed with minor amounts of three widespread tephras. The variations of chemical and mineralogical compositions are probably the reflection of local geologic settings, suggesting the presence of specific mining sites of paste materials around each tomb. The mining sites could be located at the bases of hills of granitic rocks covered by widespread tephras and in some cases, near the flood plain of big river systems.

kn-title=Epiretinal membrane: an overview and update
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Epiretinal membrane (ERM) is a frequently diagnosed macular disease associated with aging, characterized by a fibrous membrane forming on the internal limiting membrane (ILM) and leading to visual dysfunctions such as metamorphopsia. Various hypotheses regarding the pathology of metamorphopsia have been proposed; however, the complete pathophysiologic mechanism underlying ERM remains unclear. Optical coherence tomography (OCT) provides detailed images enabling precise diagnosis and characterization of ERM, with several recent studies using the latest OCT imaging techniques. Surgical removal of ERM is the only treatment option; however, criteria for surgical intervention are not established, complicating the decision-making processes. Furthermore, the debate on whether simultaneous peeling of the ILM during ERM surgery enhances outcomes or poses unnecessary risks is ongoing, with no definite conclusion having yet been reached. This review also focuses on epiretinal proliferation, which is different from ERM and is characteristic of lamellar macular hole (LMH). Recently, diagnostic criteria for LMH and related diseases were proposed. Reports on effective surgical procedures for LMH exist, although more research is needed to confirm the long-term outcomes. Thus, this review article aims to provide an overview and updated knowledge of ERM, LMH, and related diseases.

kn-title=INVESTIGATION OF THE PATHOPHYSIOLOGY OF EPIRETINAL MEMBRANE FOVEOSCHISIS: Analysis of Longitudinal Changes in Visual Functions, Retinal Structures, and Retinal Traction Force
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose: To analyze the pathophysiology of epiretinal membrane foveoschisis (FS) by evaluating the longitudinal changes in visual function and several optical coherence tomography parameters.<br>
Methods: The medical records of 33 consecutive patients (35 eyes) with untreated epiretinal membrane foveoschisis were retrospectively reviewed. Best-corrected visual acuity, M-CHARTS score, and optical coherence tomography parameters including epiretinal membrane area, maximum depth of retinal folds, FS area, and FS circularity were evaluated.<br>
Results: A wide range of FS area changes was observed at the final follow-up visit (59.68%–240.45% of the baseline FS area). In the FS enlargement group, best-corrected visual acuity and mean M-CHARTS scores significantly worsened and maximum depth of retinal folds significantly increased over time, whereas in the FS non-enlargement group, no significant change was observed in the best-corrected visual acuity, mean M-CHARTS scores, or maximum depth of retinal folds during the follow-up period. Multivariate logistic regression analyses revealed that maximum depth of retinal folds (odds ratio: 1.05, 95% confidence interval: 1.00–1.10, P = 0.048) and FS circularity (odds ratio: 0.91, 95% confidence interval: 0.83–1.00, P = 0.043) were significantly associated with FS enlargement.<br>
Conclusion: Epiretinal membrane foveoschisis encompasses diverse pathophysiologies. Since visual functions do not worsen in some cases, monitoring the changes in visual functions and retinal morphology over time is recommended to determine surgical indications.

kn-abstract=Purpose: To investigate the characteristics of mixed pathophysiologies in lamellar macular holes (LMHs) and related diseases using multimodal optical coherence tomography.<br>
Methods: Overall, 126 eyes diagnosed with LMH, epiretinal membrane foveoschisis, or macular pseudohole using the horizontal B-scan image according to the definition proposed by Hubschman et al in 2020 were analyzed using multimodal optical coherence tomography imaging including horizontal and vertical 5-line B-scan, radial scan, and macular three-dimensional volume scan images. If at least two diagnostic criteria for LMH, epiretinal membrane foveoschisis, or macular pseudohole were satisfied in these scans, the patient was diagnosed as having a “mixed type.” Retinal traction force was quantitatively evaluated by measuring the maximum depth of the retinal folds using en-face images.<br>
Results: Mixed types constituted 34.1% of the cases. The LMH-related mixed group demonstrated intermediate characteristics between the epiretinal membrane foveoschisis/macular pseudohole and true LMH groups in terms of retinal traction and LMH-specific features and had a significant positive correlation between the maximum depth of the retinal folds and mean M-CHARTS scores (P = 0.034).<br>
Conclusion: A thorough optical coherence tomography analysis is necessary to accurately diagnose LMH and related diseases. A significant positive correlation was observed between the maximum depth of the retinal folds and the degree of metamorphopsia in the LMH-related mixed group.

kn-title=Molecular Diversity of Photosensitive Protein Opsins and Their High Potential for Optogenetic Applications
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Because G protein coupled receptors (GPCRs) represent the largest family of drug targets in clinical trials, GPCR signaling cascades are closely related to various physiological phenomena, attracting significant attention in pharmaceutical science. Opsins (also known as animal rhodopsins) are photoreceptive proteins containing retinal as a chromophore, which function as GPCRs and underlie the molecular basis of photoreception in animals. Recently, opsins have been progressively applied in an innovative technology called optogenetics to regulate biological activities using light. A wide variety of opsins have been identified in metazoans and characterized at the molecular and physiological levels, providing a foundation for their optogenetic applications. In this review, I briefly introduce the diversity of opsins in terms of their molecular functions, including G protein selectivity and photoreaction properties. This diversity provides a significant advantage for optically manipulating a wide variety of GPCR signaling cascades with high temporal resolution. Additionally, I discuss the rich array of opsin-based optogenetic tools used to control various physiological processes and their potential as therapeutic tools for vision restoration. Based on the introduction, I expect that the optogenetic approach will offer powerful tools to provide valuable insights into the molecular mechanisms of various physiological phenomena and next-generation treatment options for diseases beyond the capacity of traditional drugs.

kn-title=A User Location Reset Method through Object Recognition in Indoor Navigation System Using Unity and a Smartphone (INSUS)
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=To enhance user experiences of reaching destinations in large, complex buildings, we have developed a indoor navigation system using Unity and a smartphone called INSUS. It can reset the user location using a quick response (QR) code to reduce the loss of direction of the user during navigation. However, this approach needs a number of QR code sheets to be prepared in the field, causing extra loads at implementation. In this paper, we propose another reset method to reduce loads by recognizing information of naturally installed signs in the field using object detection and Optical Character Recognition (OCR) technologies. A lot of signs exist in a building, containing texts such as room numbers, room names, and floor numbers. In the proposal, the Sign Image is taken with a smartphone, the sign is detected by YOLOv8, the text inside the sign is recognized by PaddleOCR, and it is compared with each record in the Room Database using Levenshtein distance. For evaluations, we applied the proposal in two buildings in Okayama University, Japan. The results show that YOLOv8 achieved mAP@0.5 0.995 and mAP@0.5:0.95 0.978, and PaddleOCR could extract text in the sign image accurately with an averaged CER% lower than 10%. The combination of both YOLOv8 and PaddleOCR decreases the execution time by 6.71s compared to the previous method. The results confirmed the effectiveness of the proposal.

kn-title=Design and performance of a gain calibration system for the POLARBEAR-2a receiver system at the Simons Array cosmic microwave background experiment
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We present an advanced system for calibrating the detector gain responsivity with a chopped thermal source for POLARBEAR-2a, which is the first receiver system of a cosmic microwave background (CMB) polarimetry experiment: the Simons Array. Intensity-to-polarization leakage due to calibration errors between detectors can be a significant source of systematic error for a polarization-sensitive experiment. To suppress this systematic uncertainty, POLARBEAR-2a calibrates the detector gain responsivities by observing a chopped thermal source before and after each period of science observations. The system includes a high-temperature ceramic heater that emits blackbody radiation covering a wide frequency range and an optical chopper to modulate the radiation signal. We discuss the experimental requirements of gain calibration and system design to calibrate POLARBEAR-2a. We evaluate the performance of our system during the early commissioning of the receiver system. This calibration system is promising for the future generation of CMB ground-based polarization observations.

kn-title=Presumed Choroidopathy of IgG4-Related Disease Discovered During 16-Year Follow-Up of a Patient With Polycystic Kidney Disease
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Immunoglobulin G4 (IgG4)-related disease is characterized by infiltration with IgG4-producing plasma cells in different organs and the elevation of serum IgG4. We present a patient with polycystic kidney disease in long-term follow-up who developed bilateral lacrimal gland enlargement and presumed IgG4-related choroidopathy at different time points. A 45-year-old woman developed bilateral upper eyelid swelling. Head MRI showed bilateral lacrimal gland enlargement, and the resection on both sides revealed foci of infiltration with lymphocytes and plasma cells in bilateral lacrimal glands. The IgG4-immunostaining did not satisfy the diagnostic criteria. She had been taking oral valsartan 40 mg daily for hypertension with polycystic kidney disease.<br>
<br>
The patient was well until the age of 49 years, when she noticed yellowish vision in the right eye compared to the left eye. The right eye showed multiple yellowish spotty lesions in the deep retina to choroid with a mildly hyperemic optic disc, while the left eye showed the normal fundus. No inflammation was noted in the anterior segments of both eyes. Fundus angiography demonstrated early-phase no-filling with late-phase leakage by fluorescein dye and both early-phase and late-phase no-filling by indocyanine green dye, leading to the diagnosis of acute posterior multifocal placoid pigment epitheliopathy (APMPPE). She began to have oral prednisolone tapered from 30 mg daily and discontinued in a year. At the age of 52 years, she switched to candesartan 8 mg daily and began to have tolvaptan (a selective competitive vasopressin receptor 2 (V2) antagonist) 90 mg daily for polycystic kidney disease with liver cysts. At that time, the lesions in the right eye had mild degeneration.<br>
<br>
The patient was followed once a year ophthalmologically to maintain good vision. At 57 years, serum IgG4, which was measured for the first time on suspicion of IgG4-related disease, was elevated to 269.6 mg/dL. In the following four years to the latest visit at 61 years, she kept stable but high levels of serum IgG4 around 300 mg/dL. Serum IgG4 measurement is helpful to make a clinical diagnosis and, hence, a clinical decision since the spectrum of IgG4-related disease remains obscure.

kn-title=Pathological findings in enucleated eyes of patients with neurofibromatosis type 1: report of a case with 15-year follow-up and review of 14 patients in the literature
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Backgrounds Iris nodules are frequently noted as clinical manifestations of neurofibromatosis type 1 but the other intraocular manifestations are rare. The purpose of this study is to present a patient with a phthisic eye who underwent enucleation for a cosmetic reason after 15-year follow-up and also to review 14 patients with enucleation described in the literature.<br>
Case presentation A 17-year-old man with neurofibromatosis type 1 from infancy underwent the enucleation of phthisic left eye and also had the resection of eyelid subcutaneous mass lesions on the left side for a cosmetic reason. He had undergone four-time preceding surgeries for eyelid and orbital mass reduction on the left side in childhood and had developed total retinal detachment 10 years previously. Pathologically, the enucleated eye showed massive retinal gliosis positive for both S-100 and glial fibrillary acidic protein (GFAP) in the area with involvement of the detached retinal neuronal layer, together with a more fibrotic lesion along the choroid which were, in contrast, negative for both S-100 and GFAP. The choroid, ciliary body, and iris did not show apparent neurofibroma while episcleral neurofibroma was present.<br>
Literature review In review of enucleated eyes of 14 patients in the literature, buphthalmic eyes with early-onset glaucoma on the unilateral side was clinically diagnosed in 9 patients who frequently showed varying extent of hemifacial neurofibromatosis which involved the eyelid and orbit on the same side. Pathologically, neurofibromas in varying extent were found in the choroid of 12 patients. One patient showed choroidal malignant melanoma on the left side and fusiform enlargement of the optic nerve on the right side suspected of optic nerve glioma. The phthisic eye in another patient showed massive retinal gliosis similar to the present patient.<br>
Conclusions In summary of the 15 patients with neurofibromatosis type 1, including the present patient, buphthalmic or phthisic eyes with no vision were enucleated for cosmetic reasons and showed choroidal neurofibroma in most patients and massive retinal gliosis in two patients including the present patient.

kn-title=Anterior Uveitis After Discontinuation of Janus Kinase Inhibitor, Ruxolitinib
en-subtitle=

en-abstract=
kn-abstract=Primary myelofibrosis shows widespread fibrosis in the bone marrow and is part of myeloproliferative neoplasms in which gene mutations in hematopoietic stem cells lead to abnormal clonal expansion of one or more lineage of myeloid and erythroid cells and megakaryocytes. Janus kinase (JAK) inhibitors are the main therapeutic regimen for primary myelofibrosis which harbors gene mutations, resulting in continuous activation of JAK-STAT signaling pathway. Since JAK inhibitors modulate immunological state, the administration would have a potential for uveitis. A 67-year-old patient presented with weight loss of 10 kg in the past 2 years after his retirement. He showed normocytic anemia with anisocytosis and abnormal shape, as well as hepatosplenomegaly. Suspected of hematological malignancy, bone marrow biopsy led to the diagnosis of primary myelofibrosis (grade 2) with bizarre megakaryocytes and relative maintenance of myeloid and erythroid lineage. He started to have blood transfusion. Genomic DNA analysis of the peripheral blood showed a pathogenic variant in the exon 9 of calreticulin (CALR) gene while pathogenic variants in Janus kinase-2 (JAK2), and myeloproliferative leukemia virus oncogene (MPL) were absent. He began to have oral ruxolitinib 10 mg daily at the timepoint of 5 months after the initial visit and the dose was increased to 20 mg daily 8 months later but was discontinued further 4 months later because he showed the limited effect of ruxolitinib. He had blood transfusion every week or every 2 weeks in the following 2 months until he noticed blurred vision in the right eye. The right eye showed thick fibrin membrane formation in the anterior chamber in front of the pupil which prevented the fundus from visualization. The left eye showed no inflammation and optic nerve atrophy, sequel to tuberculous meningitis in childhood. The patient started to use 0.1% betamethasone six times daily and 1% atropine once daily as eye drops. A week later, fibrin membrane disappeared and the pupillary area with total iris posterior synechia was visible in the right eye. He regained the vision in the right eye and did not show relapse of uveitis only with topical 0.1% betamethasone. Uveitis might be related with the administration and discontinuation of ruxolitinib.

kn-title=Bidirectional Optical Control of Proton Motive Force in Escherichia coli Using Microbial Rhodopsins
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Proton (H+) motive force (PMF) serves as the energy source for the flagellar motor rotation, crucial for microbial motility. Here, to control PMF using light, we introduced light-driven inward and outward proton pump rhodopsins, RmXeR and AR3, into Escherichia coli. The motility of E. coli cells expressing RmXeR and AR3 significantly decreased and increased upon illumination, respectively. Tethered cell experiments revealed that, upon illumination, the torque of the flagellar motor decreased to nearly zero (28 pN nm) with RmXeR, while it increased to 1170 pN nm with AR3. These alterations in PMF correspond to +146 mV (RmXeR) and −140 mV (AR3), respectively. Thus, bidirectional optical control of PMF in E. coli was successfully achieved by using proton pump rhodopsins. This system holds a potential for enhancing our understanding of the roles of PMF in various biological functions.

kn-title=Large-volume focus control at 10 MHz refresh rate via fast line-scanning amplitude-encoded scattering-assisted holography
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The capability of focus control has been central to optical technologies that require both high temporal and spatial resolutions. However, existing varifocal lens schemes are commonly limited to the response time on the microsecond timescale and share the fundamental trade-off between the response time and the tuning power. Here, we propose an ultrafast holographic focusing method enabled by translating the speed of a fast 1D beam scanner into the speed of the complex wavefront modulation of a relatively slow 2D spatial light modulator. Using a pair of a digital micromirror device and a resonant scanner, we demonstrate an unprecedented refresh rate of focus control of 31 MHz, which is more than 1,000 times faster than the switching rate of a digital micromirror device. We also show that multiple micrometer-sized focal spots can be independently addressed in a range of over 1 MHz within a large volume of 5 mm × 5 mm × 5.5 mm, validating the superior spatiotemporal characteristics of the proposed technique – high temporal and spatial precision, high tuning power, and random accessibility in a three-dimensional space. The demonstrated scheme offers a new route towards three-dimensional light manipulation in the 100 MHz regime.

kn-title=Volume X-Ray Micro-Computed Tomography Analysis of the Early Cephalized Central Nervous System in a Marine Flatworm, Stylochoplana pusilla
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Platyhelminthes are a phylum of simple bilaterian invertebrates with prototypic body systems. Compared with non-bilaterians such as cnidarians, the bilaterians are likely to exhibit integrated free-moving behaviors, which require a concentrated nervous system “brain” rather than the distributed nervous system of radiatans. Marine flatworms have an early cephalized ‘central’ nervous system compared not only with non-bilaterians but also with parasitic flatworms or freshwater planarians. In this study, we used the marine flatworm Stylochoplana pusilla as an excellent model organism in Platyhelminthes because of the early cephalized central nervous system. Here, we investigated the three-dimensional structures of the flatworm central nervous system by the use of X-ray micro-computed tomography (micro-CT) in a synchrotron radiation facility. We found that the obtained tomographic images were sufficient to discriminate some characteristic structures of the nervous system, including nerve cords around the cephalic ganglion, mushroom body-like structures, and putative optic nerves forming an optic commissure-like structure. Through the micro-CT imaging, we could obtain undistorted serial section images, permitting us to visualize precise spatial relationships of neuronal subpopulations and nerve tracts. 3-D micro-CT is very effective in the volume analysis of the nervous system at the cellular level; the methodology is straightforward and could be applied to many other non-model organisms.

kn-title=Photoinduced dynamics during electronic transfer from narrow to wide bandgap layers in one-dimensional heterostructured materials
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Electron transfer is a fundamental energy conversion process widely present in synthetic, industrial, and natural systems. Understanding the electron transfer process is important to exploit the uniqueness of the low-dimensional van der Waals (vdW) heterostructures because interlayer electron transfer produces the function of this class of material. Here, we show the occurrence of an electron transfer process in one-dimensional layer-stacking of carbon nanotubes (CNTs) and boron nitride nanotubes (BNNTs). This observation makes use of femtosecond broadband optical spectroscopy, ultrafast time-resolved electron diffraction, and first-principles theoretical calculations. These results reveal that near-ultraviolet photoexcitation induces an electron transfer from the conduction bands of CNT to BNNT layers via electronic decay channels. This physical process subsequently generates radial phonons in the one-dimensional vdW heterostructure material. The gathered insights unveil the fundamentals physics of interfacial interactions in low dimensional vdW heterostructures and their photoinduced dynamics, pushing their limits for photoactive multifunctional applications.

kn-title=Effect of the blend ratio of cyclic and linear polyethylene blends on isothermal crystallization in the quiescent state
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The role of entanglements that form between cyclic and linear polymers in crystallization is of particular interest, but it is not fully understood. We investigated the crystallization behaviors of blends of cyclic polyethylene (C-PE) and linear polyethylene (L-PE) in a quiescent state to elucidate the role of this novel entanglement in crystallization. The samples were prepared by mixing the prepared C-PE and L-PE specimens at L-PE weight fraction (ΦL-PE) values of 0–100 wt%, with the weight average molecular weights of C-PE and L-PE being 175 × 103 and 154 × 103, respectively. The isothermal crystallization behaviors were analyzed through polarizing optical microscopy (POM) and differential scanning calorimetry (DSC). The morphology observed through POM was similar to that of ΦL-PE. From the time evolution of the heat flow measured via DSC, we obtained the half-crystallization time (t1/2) values as functions of ΦL-PE at different degrees of supercooling (ΔT). The 1/t1/2 values of the C-PE and L-PE homopolymers were approximately the same at ΔT = 25.5 and 26.5 K. At a larger ΔT value, the 1/t1/2 value of C-PE was significantly larger than that of L-PE. In contrast, 1/t1/2 reached a minimum value at ΦL-PE = 30–40 wt%, irrespective of ΔT. As the entanglement density increased with increasing ΦL-PE, the crystallization rate was expected to decrease monotonically. By considering the experimental relationship between 1/t1/2 and ΦL-PE, we speculated that the suppression of crystallization in the blended system was caused by a novel entanglement formed by the penetration of the L-PE chain into the C-PE chain.

kn-title=Analysis on high-resolution spectrum of the S1–S0 transition of free-base phthalocyanine
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A high-resolution absorption spectrum of the S-1-S-0 transition of free-base phthalocyanine was observed and analyzed with improved reliability. The spectrum, with a partially resolved rotational structure, was obtained by using the buffer-gas cooling technique and a single-mode tunable laser. Our new analysis reveals that the S-1 <- S-0 0(0)(0) band belongs to the a-type transition, where the electronic transition moment aligns parallel to the NH-HN direction, allowing the assignment of the S-1 state to B-1(3u). These results agree with a prior study using supersonic expansion and are well supported by theoretical calculations. Interestingly, the rotational constant B in the S-1 state, which is often smaller than that in the ground state for typical molecules, was found to be slightly larger than that in the S-0 (1)A(g) state. This suggests a change in the character of pi bonds with the electronic excitation.

kn-title=Supernova Burst and Diffuse Supernova Neutrino Background Simulator for Water Cherenkov Detectors
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=If a Galactic core-collapse supernova explosion occurs in the future, it will be critical to rapidly alert the community to the direction of the supernova by utilizing neutrino signals in order to enable the initiation of follow-up optical observations. In addition, there is anticipation that observation of the diffuse supernova neutrino background will yield discoveries in the near future, given that experimental upper limits are approaching theoretical predictions. We have developed a new supernova event simulator for water Cherenkov neutrino detectors, such as the highly sensitive Super-Kamiokande. This simulator calculates the neutrino interaction in water for two simulation purposes, individual core-collapse supernova bursts and diffuse supernova neutrino background. Based on this simulator, we can evaluate the precision in determining the location of supernovae and estimate the expected number of events related to the diffuse supernova neutrino background in Super-Kamiokande. In this paper, we describe the basic structure of the simulator and its demonstration.

kn-title=Japan-epiretinal membrane (J-ERM) registry: A prospective cohort study protocol investigating the surgical outcome of epiretinal membrane
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background<br>
Epiretinal membrane (ERM) causes visual impairment such as reduction in visual acuity and metamorphopsia due to retinal traction. With the improvement of optical coherence tomography (OCT) and microincision vitrectomy surgery (MIVS), the surgery of ERM has significantly advanced. However, there have been no large-scale studies on the following: (1) how to evaluate visual impairment in ERM, (2) the relationship between OCT findings and visual function, (3) when is the optimal timing of surgery, and (4) the relationship between the surgical instruments as well as techniques and prognosis. The purpose of this study was to obtain evidence regarding these ERM surgeries.<br>
Methods and design<br>
This is a prospective, multicenter cohort study of ERM surgery in Japan from March 1, 2023, to March 31, 2027 (UMIN000048472, R-3468-2). Patients who underwent ERM surgery during the study period and agreed to participate in this study will be included. The goal is to have a total of 5,000 eyes surgically treated for ERM. The following data will be collected: age, gender, medical history, subjective symptoms, visual function before and 6 and 12 months after surgery, clinical findings, OCT data, surgical technique, instruments used in surgery, and complications.<br>
Discussion<br>
The results of this study will support the surgical decisions and procedures in ERM practices.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We observed periodic optical pulses from an Er:YSO crystal during irradiating with a continuous-wave excitation laser. We refer to this phenomenon as "periodic superradiance." This periodicity can be understood qualitatively by a simple model, in which a cyclic process of a continuous supply of population inversion and a sudden burst of superradiance is repeated. The excitation power dependences of peak interval and the pulse area can be interpreted with our simple model. In addition, the linewidth of superradiance is much narrower than an inhomogeneous broadening in a crystal. This result suggests that only Er3+ ions in a specific environment are involved in superradiance.

kn-title=Bayesian optimization of periodic multilayered slabs for passive absorptivity control
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A vanadium dioxide (VO2) film grown on a titanium oxide crystal shows a metal–insulator transition at room temperature with drastically changed optical properties. A multilayered slab with a sub-micron scale VO2 film was proposed to utilize its unique properties for passive intensity control of sunlight absorption and radiative cooling. Its optimal geometries were numerically explored using the Bayesian optimization (BO) method. BO was applied for three types of multilayered slabs, those having one, two, or three isolated slabs of different widths. For each type of multilayered slab, BO could optimize geometric variables with practical calculation times considering the total number of possible combinations of variables, which is subsequently referred to as the total number of candidates. Optimization results revealed that two isolated slabs had the most suitable spectral absorptivity in both hot and cold environments. The infrared absorptivity of the double slab was kept low in cold conditions to suppress radiative cooling. However, the double slab exhibited good radiative cooling performance under hot conditions. Electromagnetic energy density surrounding the slab illustrated that metallic VO2 and gold placed in a parallel manner excited the coupled mode of surface plasmon polaritons to enhance absorptivity. Radiative cooling faded for the triple slab because each slab could couple with radiation propagating only across a portion of the cross-sectional area. Through three BO trials, improvement of the VO2 visible reflectivity was recognized as a future issue for further development of passive sunlight absorption control.

kn-title=Rare Combination of Abducens Nerve Palsy and Optic Neuritis on the Same Side: Case Report and Review of 8 Patients in Literature
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The concurrent development of abducens nerve palsy and optic neuritis on the same side is rare. Here we presented an 82-year-old man who developed the combination of abducens nerve palsy and optic neuritis on the left side 2 months after the sixth inoculation of COVID-19 mRNA vaccine. In past history at 45 years old, he experienced subarachnoid hemorrhage and underwent surgery for the clipping of intracranial aneurysm. The patient had no systemic symptoms, such as general fatigue, fever, arthralgia, and skin rashes. Physical and neurological examinations were also unremarkable. Since the aneurysmal metal clip used at that time was not compatible with magnetic resonance imaging, he underwent computed tomographic (CT) scan of the head and showed no space-occupying lesion in the orbit, paranasal sinuses, and brain. As an old lesion, the anterior temporal lobe on the left side had low-density area with metallic artifact on the left side of the skull base, indicative of metal clipping. In 4 weeks of observation from the initial visit, he showed complete recovery of visual acuity and became capable of abducting the left eye in full degrees. We also reviewed 8 patients with the combination of abducens nerve palsy and optic neuritis in the literature to reveal that the combination of signs did occur in mild meningitis with rare infectious diseases and in association with preceding herpes zoster in the first branch of the trigeminal nerve. The course of the present patient suggested that the combination of signs might be vaccine-associated.

kn-title=Quantitative Analyses of Retinal Traction Force and Metamorphopsia in Lamellar Macular Hole and Related Diseases
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose: To investigate the involvement of retinal traction in the pathogenesis of lamellar macular hole (LMH) and related diseases based on OCT–based consensus definition. <br>
Design: Retrospective, observational study. <br>
Participants: Seventy-two eyes with LMH, epiretinal membrane foveoschisis (ERM-FS), or macular pseudohole (MPH). <br>
Methods: To quantitatively evaluate the involvement and strength of retinal traction in their pathogenesis, retinal folds were visualized with en face OCT imaging, and the maximum depth of the parafoveal retinal folds (MDRF) was measured. Metamorphopsia was quantified by measuring the minimum visual angle of dotted lines needed to cause it to disappear using M-CHARTS (Inami). <br>
Main Outcome Measures: Maximum depth of retinal folds and M-CHARTS scores. <br>
Results: Of the 72 eyes, 26 were classified as having LMH, 25 as having ERM-FS, and 21 as having MPH. Parafoveal retinal folds were observed in 7 (26.9%) eyes with LMH, 25 (100%) with ERM-FS, and 21 (100%) with MPH. The MDRF (7.5 ± 17.6 μm) was significantly smaller in LMH than in ERM-FS (86.3 ± 31.4 μm) and MPH (74.5 ± 24.6 μm) (both P < 0.001), whereas no significant difference in MDRF between MPH and ERM-FS was observed (P = 0.43). A significant positive correlation between MDRF and M-CHARTS scores was observed in ERM-FS and MPH (P = 0.008 and 0.040, respectively) but not in LMH (P = 0.073). <br>
Conclusions: Retinal traction was significantly weaker in the LMH group than in the ERM-FS and MPH groups. The MDRF was significantly associated with the degree of metamorphopsia in the ERM-FS and MPH groups. These results provide insights into the diseases’ pathophysiology and treatment strategy. <br>

kn-title=Optical multi-context scrubbing operation on a redundant system
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This paper presents a proposal of the world-first optical multi-context scrubbing operation on a redundant system that can maintain the state of a sequential circuit and the operation continuously without any interruption on a radiation-hardened optically reconfigurable gate array even after a permanent failure suddenly happens on the sequential circuit or a flip-flop by radiation. Up to now, a high-speed optical scrubbing operation has been demonstrated on a radiation-hardened optically reconfigurable gate array. In addition, a multi-context scrubbing operation based on the high-speed optical scrubbing operation has already been demonstrated. Although the multi-context scrubbing operation presents the benefit that it can treat both soft errors and permanent failures caused by radiation simultaneously, the conventional contributions have never presented how to maintain the state of a sequential circuit after a permanent failure occurs on flip-flops. Therefore, in the conventional multi-context scrubbing operation, all the operations must be restarted from the initial condition each time a permanent failure occurs on a programmable gate array. As a result, conventional multi-context scrubbing operations could not be applied for real-time systems. The proposed optical multi-context scrubbing method that can solve the issue has been experimentally evaluated on a radiation-hardened optically reconfigurable gate array.

kn-title=Assessment of epiretinal membrane formation using en face optical coherence tomography after rhegmatogenous retinal detachment repair
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose　To investigate epiretinal membrane (ERM) formation using en face optical coherence tomography (OCT) after vitrectomy for rhegmatogenous retinal detachment (RRD).<br>
Methods　We retrospectively reviewed the medical records of 64 consecutive eyes (64 patients) with RRD treated by vitrectomy without ERM and internal limiting membrane peeling. ERMs and retinal folds were detected by B-scan and en face imaging. The maximum depth of retinal folds (MDRF) was quantified using en face imaging. ERM severity was staged using B-scan imaging. Main outcome measures were ERM detection rate with B-scan and en face imaging, MDRF, ERM staging, postoperative best-corrected visual acuity (BCVA; logarithm of the minimum angle of resolution), and risk factors for ERM formation.<br>
Results　The detection rate for ERM formation was significantly higher with en face imaging (70.3%) than with B-scan imaging (46.9%; P = 0.007). There was no significant difference in postoperative BCVA between eyes with ERM formation (0.06 ± 0.26) and those without ERM formation (0.01 ± 0.14; P = 0.298). Forty of 45 (88.9%) eyes with ERM formation were classified as stage 1. Twenty-seven of 45 (60.0%) eyes with ERM formation developed parafoveal retinal folds. The mean MDRF was 27.4 ± 32.2 μm. Multiple retinal breaks and a maximum retinal break size of ≥ 2 disc diameters were significantly associated with ERM formation (P = 0.033 and P = 0.031, respectively).<br>
Conclusion　Although ERM formation was observed in 70.3% patients after RRD repair, the formed ERM was not severe and had minimal impact on the postoperative visual acuity.

kn-title=Evaluation of epiretinal membrane formation after scleral buckling for treating rhegmatogenous retinal detachment: En face optical coherence tomography image-based study
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose　To assess epiretinal membrane (ERM) formation, severity, and the associated risk factors after scleral buckling using en face optical coherence tomography (OCT) images.<br>
Methods　Medical records of 61 consecutive patients (66 eyes) with rhegmatogenous retinal detachment who underwent scleral buckling were retrospectively reviewed. Posterior vitreous detachment (PVD) was determined based on B-scan OCT images. En face OCT images were used to visualize the ERM and retinal folds. ERM formation was identified by comparing en face images pre- and post-surgery. The maximum depth of the retinal folds (MDRF) was measured using en face imaging to objectively assess traction strength.<br>
Results　ERM formation occurred in 15 (22.7%) eyes at the final visit; the foveal pit was preserved in all cases. Parafoveal retinal folds were present in 5 (7.6%) eyes, with a mean MDRF of 21.8 ± 12.6 µm. No significant difference was observed in best-corrected visual acuity (logarithm of the minimal angle of resolution) between the ERM formation (-0.019 ± 0.128) and non-ERM formation (-0.001 ± 0.213) groups at the final visit (P = 0.593; Mann-Whitney U test). Multivariate logistic regression analysis revealed that older age and the presence of PVD were significant risk factors for ERM formation (odds ratio 1.07, 95% confidence interval 1.01–1.14, P = 0.032; odds ratio 5.26, 95% confidence interval 1.06–26.10, P = 0.042; respectively).<br>
Conclusion　ERM occurred in 22.7% of cases but was mild and did not affect visual acuity. Older age and the presence of PVD are risk factors for ERM formation.

kn-title=Resection of Orbital Myxoma With Magnetic Resonance Imaging Evidence of Ethmoid Sinus Origin: Case Report and Review of 20 Patients in the Literature
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A 41-year-old woman showed a palpable mass at the superonasal orbital edge on the right side. Magnetic resonance imaging demonstrated a lobulated fluid-containing tubular mass which extended anteriorly to posteriorly along the medial orbital wall, nasal to the eyeball. She was followed once a year for 8 years until the age of 49 years when she decided to undergo surgical resection because of the enlarged mass. The lobulated large mass was resected and the pathology showed sparsely distributed spindle cells, positive for CD34, in alcian blue-positive mucous substances, indicative of myxoma. Postoperative magnetic resonance imaging showed residual lobulated tubular mass along the optic nerve on the medial side and superior to the eyeball. The residual orbital mass showed stable structure with more evident connection with the ethmoid sinus lesion, suggestive of the ethmoid origin, in 12 years until the age of 61 years. In the review of 20 patients with orbital myxomas in the literature, in addition to this case, roughly classified locations in the orbit were retrobulbar in 8 patients, on the lateral side of the orbit in 4, on the superior side in 6, on the medial side in 1 (this patient), and in the orbit with no specific description in 2. In pathological examinations, immunohistochemistry was not done in 8 patients, done but all negative in 2, and positive in 11 patients: nerve sheath myxoma was diagnosed in 3 patients based on positive S100 staining. Orbital myxoma is rare but considered in differential diagnosis of orbital masses.

kn-title=Effects of the rigid and sterically bulky structure of non-fused nonfullerene acceptors on transient photon-to-current dynamics
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Non-fused electron-accepting π-conjugated compounds have been investigated recently for application to nonfullerene acceptors (NFAs) in organic solar cells (OSCs). However, the establishment of rational molecular design for non-fused NFAs is still lagging because the influence of flexible non-fused structures on the dynamics of electron–hole pairs in OSCs is not entirely understood. In this study, we utilized cyclopentene-annelated thiophene with spiro-substituted 2,7-bis(2-ethylhexyl)fluorene (FT) as a rigid and sterically bulky linker unit and developed a non-fused NFA (TT–FT–DCI) containing FT units. Photophysical measurements indicated that the introduction of the FT unit leads to the formation of rigid molecular structure. OSCs based on donor polymer (PBDB-T) and TT–FT–DCI showed an improved power conversion efficiency of 7.13% due to the increase in the short-circuit current density and fill factor. Time-resolved optical and microwave spectroscopies showed that the FT unit contributes to the long lifetimes of excited state and charge-separated state in the PBDBT:TT–FT–DCI blend films. Time-resolved electron paramagnetic resonance measurements showed that the distant charge-separated states of the face-to-face PBDB-T:TT–FT–DCI structure, which is derived by avoiding over-crystallization by the steric bulkiness of TT–FT–DCI, can interact with the cathodes for preferential electron injection following charge generations. This study highlights that by using the rigid π-conjugated framework and suppressed self-aggregation of the non-fused acceptor, effective molecular design for the appropriate dynamics of photocurrent generation is possible.

kn-title=A Case of Acute Zonal Occult Outer Retinopathy in which Oct en Face Imaging Was Useful for Diagnosis and Follow-up
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A 23-year-old woman presented with a 1-month history of visual abnormalities in her right eye. A visual field test revealed temporal abnormalities in the right eye. Optical coherence tomography revealed an indistinct ellipsoid zone (EZ) on the B-scan image and hyporeflective areas in the EZ layer on the en face image in the right eye. We diagnosed the patient with acute zonal occult outer retinopathy. Visual field tests and B-scan images improved to almost normal at 6 months, but hyporeflective areas remained on the en face images. Thus, en face images may be more sensitive at detecting abnormalities in the outer retina than other modalities.

kn-title=Accuracy of ultrasound vs. Fourier-domain optic biometry for measuring preoperative axial length in cases of rhegmatogenous retinal detachment
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose To identify a method for accurately measuring preoperative axial length (AL) in cases of rhegmatogenous retinal detachment (RRD).<br>
Study design Retrospective study.<br>
Methods This retrospective study included 83 eyes of 83 patients who underwent vitrectomy for RRD and had both preoperative and postoperative data for AL. Preoperative AL measurements for the affected eye were obtained using ultrasound (aUS-AL) and compared with those for affected and fellow eyes measured using optical biometry (aOB-AL and fOB-AL, respectively). Absolute differences between preoperative aUS-AL, aOB-AL, or fOB-AL measurements and postoperative AL (aPost-AL) were examined.<br>
Results In the 41 eyes without macular detachment, the absolute difference between aOB-AL and aPost-AL (0.06±0.07 mm) was significantly smaller than between aUS-AL and aPost-AL (0.21±0.18 mm) and that between fOB-AL and aPost-AL (0.29±0.35 mm) (P = 0.017 and P < 0.001, respectively). In the 42 eyes with macular detachment, the absolute difference between aOB-AL and aPost-AL (1.22±2.40 mm) was significantly larger than between aUS-AL and aPost-AL (0.24±0.24 mm) and between fOB-AL and aPost-AL (0.35±0.49 mm) (P = 0.006, P = 0.016, respectively).<br>
Conclusion The current findings suggest that aOB-AL is more accurate than aUS-AL or fOB-AL in cases of RRD without macular detachment, while aUS-AL or fOB-AL is more accurate than aOB-AL in cases with macular detachment.

kn-title=Bilateral Optic Neuritis and Hypophysitis With Diabetes Insipidus 1 Month After COVID-19 mRNA Vaccine: Case Report and Literature Review
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Either optic neuritis (neuropathy) or hypopituitarism has been known to occur separately after COVID-19 vaccination. In this report, we describe the rare combination of hypophysitis and optic neuritis which occurred after COVID-19 vaccination. A 74-year-old woman began to have thirst, polydipsia, and polyuria, and was diagnosed as central diabetes insipidus 1 month after the fourth COVID-19 mRNA vaccine. Head magnetic resonance imaging (MRI) disclosed the thickened pituitary stalk and enlarged pituitary gland with high contrast enhancement as well as the absence of high-intensity signals in the posterior pituitary lobe on the T1-weighted image, leading to the diagnosis of lymphocytic hypophysitis. She was well with desmopressin nasal spray until further 2 months later, when she developed bilateral optic neuritis, together with gait disturbance, intention tremor of the upper extremities, urinary retention, constipation, abnormal sensation in the distal part of the lower extremities, and moderate hemiplegia on the left side. Autoantibodies, including anti-aquaporin 4 (AQP4) and anti-myelin oligodendrocyte glycoprotein (MOG), were all negative. She showed multifocal spinal cord lesions on MRI and oligoclonal bands in the cerebrospinal fluid obtained by spinal tap, and so underwent steroid pulse therapy with methylprednisolone in the tentative diagnosis of multiple sclerosis, resulting in visual acuity recovery and alleviation of neurological symptoms. In the literature review, the combination of optic neuritis and hypophysitis, mostly with diabetes insipidus, was reported in 15 patients as case reports before the years of COVID-19 pandemic. The COVID-19 vaccination would trigger the onset of hypophysitis and optic neuritis in this patient.

kn-title=A factor for predicting simultaneous internal limiting membrane peeling during epiretinal membrane removal: swept-source optical coherence tomography-based evaluation of epiretinal membrane adhesion to the retina
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose　To investigate preoperative factors associated with simultaneous internal limiting membrane (ILM) peeling during epiretinal membrane (ERM) removal.<br>
Study design　Observational cross-sectional study.<br>
Methods　We retrospectively reviewed 60 eyes with idiopathic ERM that underwent vitrectomy. The gap between the ERM and ILM was visualized using en face optical coherence tomography. The depth and width of the ERM–ILM gap at the initiation site of ERM removal were measured, and the relationship between preoperative factors including these parameters and simultaneous ILM peeling during ERM removal was investigated.<br>
Results　The ILM was simultaneously peeled during ERM removal in 30 eyes, but not in the other 30 eyes. Age was significantly higher (P = 0.017) and the width of the ERM–ILM gap was significantly smaller (P < 0.001) in the simultaneous ILM peeling (+) group than in the simultaneous ILM peeling (–) group. Multivariate logistic regression analysis confirmed the width of the ERM–ILM gap as a significant negative predictor for simultaneous ILM peeling (odds ratio, 0.992; 95% confidence interval, 0.986–0.997; P = 0.003). Receiver operating characteristic curve analysis of the width of the ERM–ILM gap revealed that the optimal cutoff for predicting simultaneous ILM peeling was 187.1 µm.<br>
Conclusion　The small width of the ERM–ILM gap at the initiation site of ERM removal was significantly associated with simultaneous ILM peeling, indicating that the adhesion strength between the ERM and ILM at the initial ERM grasping site determines whether simultaneous ILM peeling will occur during ERM removal.

kn-title=Measurement of Doppler effects in a cryogenic buffer-gas cell
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Buffer-gas cooling is a universal cooling technique for molecules and used for various purposes. One of its ap- plications is using molecules inside a buffer-gas cell for low-temperature spectroscopy. Although a high-intensity signal is expected in the cell, complex molecular dynamics is a drawback for precise spectroscopy. In this study, we performed high-resolution absorption spectroscopy of low -J transitions in the &Atilde;&sup2;Π(0, 0, 0)-˜X&sup2;Σ<sup>+</sup>(0, 0, 0) band of calcium monohydroxide (CaOH). CaOH molecules were produced by laser ablation in a copper cell and cooled to ∼5 K using helium buffer gas. We probed the Doppler effects in a buffer-gas cell by injecting counterpropagating lasers inside the cell. The time evolutions of the Doppler width and shift were simulated using a dedicated Monte Carlo simulation and compared with data.

kn-title=High-sensitivity low-noise photodetector using a large-area silicon photomultiplier
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The application of silicon photomultiplier (SiPM) technology for weak-light detection at a single photon level has expanded thanks to its better photon detection efficiency in comparison to a conventional photomultiplier tube (PMT). SiPMs with large detection area have recently become commercially available, enabling applications where the photon flux is low both temporarily and spatially. On the other hand, several drawbacks exist in the usage of SiPMs such as a higher dark count rate, many readout channels, slow response time, and optical crosstalk; therefore, users need to carefully consider the trade-offs. This work presents a SiPM-embedded compact large-area photon detection module. Various techniques are adopted to overcome the disadvantages of SiPMs so that it can be generally utilized as an upgrade from a PMT. A simple cooling component and recently developed optical crosstalk suppression method are adopted to reduce the noise which is more serious for larger-area SiPMs. A dedicated readout circuit increases the response frequency and reduces the number of readout channels. We favorably compare this design with a conventional PMT and obtain both higher photon detection efficiency and larger-area acceptance.

kn-title=Detection of Membrane Potential-Dependent Rhodopsin Fluorescence Using Low-Intensity Light Emitting Diode for Long-Term Imaging
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Microbial rhodopsin is a family of photoreceptive membrane proteins that commonly consist of a seven-transmembrane domain and a derivative of vitamin-A, retinal, as a chromophore. In 2011, archaeorhodopsin-3 (AR3) was shown to exhibit voltage-dependent fluorescence changes in mammalian cells. Since then, AR3 and its variants have been used as genetically encoded voltage indicators, in which mostly intense laser stimulation (1-1000 W/cm(2)) is used for the detection of dim fluorescence of rhodopsin, leading to high spatiotemporal resolution. However, intense laser stimulation potentially causes serious cell damage, particularly during long-term imaging over minutes. In this study, we present the successful detection of voltage-sensitive fluorescence of AR3 and its high fluorescence mutant Archon1 in a variety of mammalian cell lines using low-intensity light emitting diode stimulation (0.15 W/cm2) with long exposure time (500 ms). The detection system enables real-time imaging of drug-induced slow changes in voltage within the cells for minutes harmlessly and without fluorescence bleaching. Therefore, we demonstrate a method to quantitatively understand the dynamics of slow changes in membrane voltage on long time scales.

kn-title=A Proposal of Printed Table Digitization Algorithm with Image Processing
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Nowadays, digital transformation (DX) is the key concept to change and improve the operations in governments, companies, and schools. Therefore, any data should be digitized for processing by computers. Unfortunately, a lot of data and information are printed and handled on paper, although they may originally come from digital sources. Data on paper can be digitized using an optical character recognition (OCR) software. However, if the paper contains a table, it becomes difficult because of the separated characters by rows and columns there. It is necessary to solve the research question of "how to convert a printed table on paper into an Excel table while keeping the relationships between the cells?" In this paper, we propose a printed table digitization algorithm using image processing techniques and OCR software for it. First, the target paper is scanned into an image file. Second, each table is divided into a collection of cells where the topology information is obtained. Third, the characters in each cell are digitized by OCR software. Finally, the digitalized data are arranged in an Excel file using the topology information. We implement the algorithm on Python using OpenCV for the image processing library and Tesseract for the OCR software. For evaluations, we applied the proposal to 19 scanned and 17 screenshotted table images. The results show that for any image, the Excel file is generated with the correct structure, and some characters are misrecognized by OCR software. The improvement will be in future works.

kn-title=Involvement of a Basic Helix-Loop-Helix Gene BHLHE40 in Specification of Chicken Retinal Pigment Epithelium
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The first event of differentiation and morphogenesis in the optic vesicle (OV) is specification of the neural retina (NR) and retinal pigment epithelium (RPE), separating the inner and outer layers of the optic cup, respectively. Here, we focus on a basic helix-loop-helix gene, BHLHE40, which has been shown to be expressed by the developing RPE in mice and zebrafish. Firstly, we examined the expression pattern of BHLHE40 in the developing chicken eye primordia by in situ hybridization. Secondly, BHLHE40 overexpression was performed with in ovo electroporation and its effects on optic cup morphology and expression of NR and RPE marker genes were examined. Thirdly, we examined the expression pattern of BHLHE40 in LHX1-overexpressed optic cup. BHLHE40 expression emerged in a subset of cells of the OV at Hamburger and Hamilton stage 14 and became confined to the outer layer of the OV and the ciliary marginal zone of the retina by stage 17. BHLHE40 overexpression in the prospective NR resulted in ectopic induction of OTX2 and repression of VSX2. Conversely, BHLHE40 was repressed in the second NR after LHX1 overexpression. These results suggest that emergence of BHLHE40 expression in the OV is involved in initial RPE specification and that BHLHE40 plays a role in separation of the early OV domains by maintaining OTX2 expression and antagonizing an NR developmental program.

kn-title=High-resolution spectroscopy of buffer-gas-cooled phthalocyanine
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=For over five decades, studies in the field of chemical physics and physical chemistry have primarily aimed to understand the quantum properties of molecules. However, high-resolution rovibronic spectroscopy has been limited to relatively small and simple systems because translationally and rotationally cold samples have not been prepared in sufficiently large quantities for large and complex systems. In this study, we present high-resolution rovibronic spectroscopy results for large gas-phase molecules, namely, free-base phthalocya-nine (FBPc). The findings suggest that buffer-gas cooling may be effective for large molecules introduced via laser ablation. High-resolution electronic spectroscopy, combined with other experimental and theoretical studies, will be useful in understanding the quantum properties of molecules. These findings also serve as a guide for quantum chemical calculations of large molecules.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Extracellular vesicles (EVs) exist in biological fluids such as blood, urine, and cerebrospinal fluid and are promising cancer biomarkers. Attempts to isolate and analyze trace EVs, however, have been a challenge for researchers studying their functions and secretion mechanisms, which has stymied the options for diagnostic application. This study demonstrated a collection of EVs that was enhanced by gold nanoparticles (AuNPs) via the use of optical force. The collection system consists of an inverted microscope equipped with a CCD camera, a square capillary connected with a PTFE tube, and an Nd:YAG laser that generates optical force. The laser beam was focused on a capillary wall in which a cell culture medium containing EVs flowed continuously. Control of the surface charges on both the capillary wall and the AuNPs achieved the collection and retention of EVs on the capillary wall. The positively charged capillary wall retained EVs even after the laser irradiation was halted due to the negative charges inherent on the surface of EVs. Conversely, positively charged AuNPs had a strong electrostatic interaction with EVs and enhanced the optical force acting on them, which made collecting them a much more efficient process.

kn-title=Constant Light, Pdp1, and Tim Exert Influence on Free-Running Period of Locomotor Rhythms in the Cricket Gryllus bimaculatus
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Most insects show circadian rhythms of which the free-running period changes in a light-dependent manner and is generally longer under constant light (LL) than under constant dark conditions in nocturnal animals. However, the mechanism underlying this LL-dependent period change remains unclear. Here, using the cricket Gryllus bimaculatus, we examined the effects of long-term LL exposure on the free-running period of locomotor rhythms. Initially, the free-running period was considerably longer than 24 h but it gradually became shorter during long-term exposure to LL. The initiallengthening and ensuing gradual shortening under long-term LL exposure were observed evenafter unilateral removal of the optic lobe. Thus, these changes in the free-running period could be attributable to a single optic lobe clock. RNA interference (RNAi)-mediated silencing of the clock genes Par domain protein 1 (Pdp1) and timeless (tim) revealed that the treatments eliminated the initial period lengthening by LL without reducing circadian photoreceptor gene expression. However, they did not affect the period shortening during long-term LL exposure. The slopes of the regression line for the period change during long-term LL for Pdp1RNAi-treated and timRNAi-treated crickets were not different from that of the dsDsRed2-treated control. These results suggest that the initial period lengthening after transfer to LL requires tim and Pdp1, while the ensuing period shortening during long-term LL exposure is caused by a mechanism independent of tim and Pdp1.

In total, 40 transitions out of the low-<jats:italic>J</jats:italic> states were assigned, including 27 transitions that have not been reported in previous literature. The determined rotational constants for both ground and excited states are in excellent agreement with previous literature, and the measurement uncertainty for the absolute transition frequencies was improved by more than a factor of 3. This will aid future interstellar, circumstellar, and atmospheric identifications of CaOH. The buffer-gas-cooling method employed here is a particularly powerful method to probe low-<jats:italic>J</jats:italic> transitions and is easily applicable to other astrophysical molecules.</jats:p>

kn-title=Efficacy of 0.01% Atropine Eye Drops in Controlling Myopia Progression and Axial Elongation in Children: A Meta-analysis Based on Randomized Controlled Trials
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=To clarify the preventive effects of 0.01% atropine eye drops against myopia progression and axial elongation in children, a meta-analysis was carried out based on data obtained from PubMed and Web of Science as of August 1, 2021. Randomized controlled trials (RCTs) that enrolled myopic children who had received atropine for at least one year were included in this study, Key search terms included myopia, children, and 0.01% or low-dose atropine. Heterogeneity was quantified by I2 statistics, and meta-analyses were performed using the fixed-effect model. Five RCTs involving 809 unique children were analyzed. One trial was excluded because of a poor Jadad score and markedly rapid myopia progression in controls. The mean effect sizes for 12 months in myopia progression and axial elongation synthesized from the remaining 4 RCTs were 0.20 (95% CI: 0.13 to 0.27) D and −0.08 (−0.11 to −0.04) mm, respectively (p<0.0001). The corresponding inhibition ratios were 28%
and 19%. I2 statistics were 6% or less. Sensitivity analysis and funnel plots demonstrated the robustness of the estimation. The 0.01% atropine-induced inhibition ratio for myopia progression in Asian children was roughly half of that originally reported and did not reach the minimum requirement for clinical treatment.

kn-title=5-Nitro-2-(3-phenylpropylamino) Benzoic Acid Inhibits the Proliferation and Migration of Lens Epithelial Cells by Blocking CaMKII Signaling
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Posterior capsule opacification (PCO) is a post-surgery complication of cataract surgery, and lens epithelial cells (LECs) are involved in its development. A suppressive effect on LECs is exerted by the non specific chloride channel inhibitor 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB) exerts. Herein, the growth and migration inhibitory effects of NPPB on LECs were assessed, and the mechanism underlying the effects were investigated by focusing on Ca2+/CaMKII signaling. LECs were treated with different concentrations of NPPB, and the changes in cell viability, cell-cycle distribution, anchorage-dependent growth, migration, Ca2+ level, and CaMKII expression were evaluated. NPPB inhibited LECs’ proliferation and induced G1 cell-cycle arrest in the cells. Regarding LECs’ mobility, NPPB suppressed the cells’ anchorage-dependent growth ability and inhibited their migration. Changes in cell phenotypes were associated with an increased intracellular Ca2+ level and down-regulation of CaMKII. Together these results confirmed the inhibitory effect of NPPB on the proliferation and migration of LECs, and the effect was shown to be associated with the induced level of Ca2+ and the inhibition of CaMKII signaling transduction.

kn-title=Bilateral Blunt Ocular Trauma Caused by an Exercise Resistance Band during Muscle Building Exercise for Swimming
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=An 18-year-old male high school student presented to our clinic with bilateral blunt ocular trauma caused by an exercise resistance band (ERB) during a muscle-building exercise. Best-corrected decimal visual acuities (BCVAs) for right and left eyes were light perception and 0.15, respectively. The right eye was operated 10 days after injury for persistent vitreous hemorrhage, and the left eye 5 months later because of macular hole onset. After 36 months, the right eye showed extensive retinal degeneration (BCVA 0.04), and the left eye macular hole closure (BCVA 1.2). ERBs should be used cautiously as they can cause serious ocular trauma.

kn-abstract=Increasing the dispersibility of cellulose nanocrystals (CNCs) as a reinforcing material is highly desirable to obtain composites with enhanced mechanical properties. To this aim, nanocomposite fibers (NCF(CNC/polymer)) were fabricated by coating CNCs with polymer crystals. Poly(vinyl alcohol) (PVA) and poly(vinyl alcohol-co-ethylene) (EVOH) were crystallized from a dilute solution in the presence of CNCs, which acted as nucleating agents for polymer crystal growth on the CNC surface. NCF consisting of CNCs coated with PVA crystals (NCF(CNC/PVA)) and CNCs coated with EVOH crystals (NCF(CNC/EVOH)) were successfully obtained. Both NCF(CNC/polymer) showed good dispersibility in water, even after drying, and were used to prepare composite films with improved mechanical properties. The reinforcement effect of NCF(CNC/PVA) was greater than that of pure CNCs and NCF(CNC/EVOH). The PVA composite films exhibited optical transmittance above 99% compared with additive-free PVA films. No agglomerates appeared even under the optical microscopic observation of the PVA composite film, and NCF(CNC/PVA) dispersibility was extremely good. NCF(CNC/PVA)-added PVA composite films exhibited increased glass transition temperature compared with additive-free PVA films, and the crystallinity of the PVA film increased. The highly dispersed CNCs in the PVA matrix and the increase in the glass transition temperature and crystallinity caused an increase in the mechanical modulus of the PVA composite film at low NCF(CNC/PVA) content. Furthermore, the effect of the morphologies of cellulose nanofibers and CNCs on the mechanical properties of the composite films prepared using the respective NCFs was investigated.

kn-title=Microfluidic Paper-based Analytical Devices Coupled with Coprecipitation Enrichment Show Improved Trace Analysis of Copper Ions in Water Samples
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The present study was focused on improving sensitivity to trace levels of Cu(II) by subjecting microfluidic paper based analytical devices (μ PADs) to a preconcentration process via coprecipitation using aluminum hydroxide. The experimental conditions were optimized for the pH of the coprecipitation, centrifugation, and amounts of reagents that were deposited onto µ PADs for Cu(II) assay. The resultant limit of detection reached as low as 0.003 mg L 1 with a linear range of 0.01 2.00 mg L 1 . The relative standard deviations for intra and inter day precision were 3.2 and 4.6%, respectively (n = 9). Spiked water samples were analyzed using the μ PADs after coprecipitation preconcentration. The results were verified by comparing them with thos e of inductively coupled plasma optical emission spectrometry (ICP OES). Recoveries ranged from 97.1 104% and from 98.7 105% using the present method and ICP OES, respectively. These results suggest that the simple, highly sensitive, and inexpensive propos ed method would be helpful for analyzing trace levels of Cu(II) in water samples in poorly equipped laboratories.

kn-title=Displacement Sensing of an Active String Actuator Using a Step-Index Multimode Optical Fiber Sensor
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A thin McKibben artificial muscle is a pneumatic actuator with an outer diameter of only 1.8 mm. We fabricated a string-shaped actuator called an "active string actuator," which achieves a high contractile displacement by accumulating thin McKibben artificial muscles. To control the displacement, the length of the active string actuator should be estimated. However, this is difficult because bulky and rigid sensors are unsuitable for the sensor element of the active string actuator. Therefore, in this study, we propose a new sensing method for estimating the length of an active string actuator. The proposed sensing system is simple and comprises only three components: a step-index multimode optical fiber, a light emitter, and a light receiver. A step-index multimode optical fiber was combined with the active string actuator, and the length was estimated from the change in the amount of light propagating in the optical fiber when the active string actuator was driven. Fundamental experiments were conducted in this study, and the results demonstrated that the optical fiber sensor value changed with the actuator length. This suggests that it is possible to estimate the displacement of an active string actuator using an optical fiber sensor.

kn-title=Glass-patternable notch-shaped microwave architecture for on-chip spin detection in biological samples
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We report a notch-shaped coplanar microwave waveguide antenna on a glass plate designed for on-chip detection of optically detected magnetic resonance (ODMR) of fluorescent nanodiamonds (NDs). A lithographically patterned thin wire at the center of the notch area in the coplanar waveguide realizes a millimeter-scale ODMR detection area (1.5 × 2.0 mm2) and gigahertz-broadband characteristics with low reflection (∼8%). The ODMR signal intensity in the detection area is quantitatively predictable by numerical simulation. Using this chip device, we demonstrate a uniform ODMR signal intensity over the detection area for cells, tissue, and worms. The present demonstration of a chip-based microwave architecture will enable scalable chip integration of ODMR-based quantum sensing technology into various bioassay platforms.

kn-title=Objective and quantitative estimation of the optimal timing for epiretinal membrane surgery on the basis of metamorphopsia
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose: To establish an objective and quantitative biomarker of metamorphopsia in epiretinal membranes (ERMs) and determine the optimal timing for ERM surgery. <br>
Methods: Retrospectively, 172 eyes with ERM were reviewed. Retinal folds due to tangential traction by ERM were visualized by en face optical coherence tomography (OCT). The maximum depth of retinal folds (MDRF) within the parafovea was quantified. Metamorphopsia was quantified by M-CHARTS. The change in the distance between the retinal vessels after ERM surgery and the preoperative total depth of retinal folds between the vessels were quantified using en face OCT and OCT angiography. <br>
Results: Significant correlations were observed between preoperative MDRF and M-CHARTS scores before and at 6 months after surgery (r=0.617 and 0.460, respectively; P<0.001) and change in the distance between the retinal vessels after ERM surgery and preoperative total depth of retinal folds between the vessels (r=0.471, P=0.013). The preoperative MDRF values at which M-CHARTS scores were 0.5 before and 6 months after surgery were 69 μm and 118 μm, respectively. <br>
Conclusion: MDRF is an objective and quantitative biomarker of metamorphopsia in ERM. To maintain patients’ quality of vision, ERM surgery may be performed when the preoperative MDRF ranges between 69 and 118 μm.

kn-abstract=Optogenetics, a technology to manipulate biological phenomena thorough light, has attracted much attention in neuroscience. Recently, the Magnet System, a photo-inducible protein dimerization system which can control the intracellular behavior of various biomolecules with high accuracy using light was developed. Furthermore, photoactivation systems for controlling biological phenomena are being developed by combining this technique with genome-editing technology (CRISPR/Cas9 System) or DNA recombination technology (Cre-loxP system). Herein, we review the history of optogenetics and the latest Magnet System technology and introduce our recently developed photoactivatable Cre knock-in mice with temporal-, spatial-, and cell-specific accuracy.

kn-title=Absorptivity Control Over the Visible to Mid-Infrared Range Using a Multilayered Film Consisting of Thermochromic Vanadium Dioxide
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Vanadium dioxide (VO<sub>2</sub>) is a phase transition material that exhibits metallic or insulating characteristics depending upon its temperature. In this study, a multilayered film consisting of <sub>2</sub>, silicon dioxide (SiO<sub>2</sub>) and gold was proposed as a metamaterial that switches its absorptivity over a broad wavelength range depending on the ambient temperature as a fundamental element of a building pigment. At high temperatures, the multilayer showed a high absorptivity at mid-infrared wavelengths, promoting radiative cooling. Simultaneously, the multilayer presented a low absorptivity in the visible and near-infrared wavelengths, enhancing sunlight absorption. The daily average heat flux can possibly be suppressed in summer in comparison with a gray body whose emissivity was 0.8. Conversely, at a lower temperatures, the multilayer showed opposite absorptivity in both the mid-infrared and visible ranges, and its daily average heat flux increased in winter. The metal–insulator phase transition of VO<sub>2</sub> caused a drastic shift of the resonant wavelength related to surface phonons and surface plasmons at an infrared wavelength, and optical interference at a visible wavelength, originating at the interface of the SiO<sub>2</sub> layer. Thus, the radiative heat flux for both sunlight absorption and radiative cooling was simultaneously controlled depending on the temperature of VO<sub>2</sub>.

kn-abstract=The formation mechanism of αAA–martensite (αAAMt) induced by tempering at 450–550℃ for a short time was investigated using Ti–10Mo–7Al alloy. The solution treated and quenched (STQ) sample was composed of β phase and a small amount of αAAMq, and a large amount of αAAMt was generated by rapid tempering at 550℃–3 s using a salt bath. However, αAAMt was completely transformed into a single β phase by aging at 200℃ for 3 min. Reversibility was observed between the αAAMt transformation and the β reverse transformation. In–situ high–temperature X–ray diffraction measurements revealed that αAAMq → β reverse transformation occurred at 200℃ and that a thermally activated αAAiso was generated at
450℃ due to the slow heating rate. In–situ optical microscopic observation of STQ sample with rapid lamp heating revealed that αAAMt was formed during heating process. However, αAAMt did not generate under following conditions; that is, a slow heating rate, thin sample plate, and a small temperature difference until tempering by preheating. On the other hand, rapid tempering using thick plate from liquid nitrogen (−196℃) to 250℃ was performed to ensure a sufficient temperature difference, but αAAMt was not generated at all.
From the cross–sectional observation of the STQ plate, it was found that αAAMq was hardly formed on the surface of the sample, but was formed abundantly inside the sample. On the other hand, in the rapidly tempered plate, a large amount of αAAMt was distributed in the surface layer than inside sample. These results suggest that the thermal compressive stress induced by rapid heat treatment contributes to the formation of α''M.

kn-title=Bilateral Optic Disc Swelling as a Plausible Common Ocular Sign of Autoinflammatory Diseases: Report of Three Patients with Blau Syndrome or Cryopyrin-Associated Periodic Syndrome
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The aim of this study is to describe bilateral optic disc swelling in three consecutive patients with Blau syndrome or cryopyrin-associated periodic syndrome at a single institution. Case 1 was a 30-year-old woman receiving 25 mg etanercept twice weekly who had been diagnosed as early-onset sarcoidosis by biopsy of skin rashes at 5 months old and genetically diagnosed with Blau syndrome with CARD15/NOD2 mutation (N670K) at 13 years old. At 10 years old, she began to have uveitis with optic disc swelling in both eyes, resulting in macular degeneration and optic disc atrophy at 17 years old only when etanercept was introduced. Case 2 was a 21-year-old man receiving adalimumab every 2 weeks who had been diagnosed as early-onset sarcoidosis by biopsy of skin rashes at 1.5 years old and genetically diagnosed as Blau syndrome with CARD15/NOD2 mutation (C495Y) at 5 years old. At 8 years old, around the time of adalimumab introduction, he began to show bilateral optic disc swelling which continued until the age of 16 years when the dose of adalimumab was increased. Case 3 was a 20-year-old woman receiving canakinumab every 8 weeks for systemic symptoms such as fever, headache, vomiting, and abdominal pain and later for sensorineural hearing disturbance on both sides. She had been diagnosed genetically with cryopyrin-associated periodic syndrome with NLRP3 mutation (Y859C) at 7 years old. At 5 years old, she was found to have bilateral optic disc swelling, which continued until the age of 10 years when she began receiving canakinumab (IL-1β inhibitor). Bilateral optic disc swelling might be tentatively designated as a plausible common ocular feature, if it occurred, in autoinflammatory diseases to pay more attention to ophthalmic complications in rare diseases.

kn-title=Sublingual Gland Carcinoma Revealed by Choroidal Metastasis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A 65-year-old man presented with a 1-week history of left eye distortion. An elevated choroidal lesion covering 6 disc diameters was found in the posterior retina of the left eye. Systemic examination revealed sublingual gland carcinoma and multiple lung metastases, and the diagnosis was choroidal metastasis from sublingual gland carcinoma. Following chemotherapy and radiation therapy, the choroidal lesion shrunk and the patient’s visual acuity improved. The patient died 23 months after his first visit. To the best of our knowledge, this is the first reported case of choroidal metastasis from sublingual gland carcinoma.

kn-title=Surgical Treatment of Epiretinal Membrane
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Epiretinal membrane (ERM) is a common retinal disease characterized by cellular proliferation and metaplasia that lead to the formation of a pathological fibrocellular membrane immediately superjacent to the inner retinal surface. The vast majority of ERMs are considered idiopathic. However, ERM formation can result from various primary intraocular diseases, including retinal breaks and detachment, retinal vascular diseases, and vitreoretinal inflammatory conditions. Although ERMs are generally asymptomatic or cause mild metamorphopsia and/or a modest decrease in visual acuity, some can cause severe macular distortion and macular edema, resulting in significantly impaired function. Surgical removal of ERM is the only treatment, and improvements in vitrectomy systems have enabled less invasive treatment. However, there are currently no standardized criteria for ERM surgery, and the indications for surgery are determined from the patient’s subjective symptoms. Another problem with ERM surgery is that not all patients show satisfactory postoperative recovery of visual function. Thus, further research is needed to determine the criteria for ERM surgery and methods to improve the postoperative prognosis.

kn-title=Embedding of Epiretinal Proliferation for a Secondary Lamellar Macular Hole 12 Years after Rhegmatogenous Retinal Detachment Repair
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A 58-year-old Japanese man underwent vitrectomy for rhegmatogenous retinal detachment (RRD) in 2002. Twelve years later, optical coherence tomography revealed the development of a lamellar macular hole; the visual acuity was 20/200. Two years later, because metamorphopsia and the foveal retina thinning were aggravated, epiretinal proliferation embedding was performed to restore the foveal structure by transplanting glial cells to the foveal cavity. The patient was followed-up for 4 years, and his macular morphology and visual acuity (20/66) improved. No complications occurred. This appears to be the first report of epiretinal proliferation embedding for a lamellar macular hole post-RRD repair.

kn-abstract=We propose and study a method of optical crosstalk suppression for silicon photomultipliers (SiPMs) using optical filters. We demonstrate that attaching absorptive visible bandpass filters to the SiPM can substantially reduce the optical crosstalk. Measurements suggest that the absorption of near infrared light is important to achieve this suppression. The proposed technique can be easily applied to suppress the optical crosstalk in SiPMs in cases where filtering near infrared light is compatible with the application.

kn-abstract=Synthesis of assumed natural (12R,13S)-enantiomers of pyriculariol (1) and dihydropyriculariol (2), phytotoxins isolated from rice blast disease fungus, Pyricularia oryzae, was achieved using Wittig reaction or microwave-assisted Stille coupling reaction as the key step. The synthesis revealed that the natural 1 and 2 are racemates. Foliar application test on a rice leaf indicated that both the salicylaldehyde core and side chain were necessary for phytotoxic activity. The fungus is found to produce optically active phytotoxins when incubated with rotary shaker, but racemic ones when cultured using an aerated jar fermenter.

en-abstract=
kn-abstract=This retrospective study was performed to classify diabetic macular edema (DME) based on the localization and area of the fluid and to investigate the relationship of the classification with visual acuity (VA). The fluid was visualized using en face optical coherence tomography (OCT) images constructed using swept-source OCT. A total of 128 eyes with DME were included. The retina was segmented into: Segment 1, mainly comprising the inner nuclear layer and outer plexiform layer, including Henle's fiber layer; and Segment 2, mainly comprising the outer nuclear layer. DME was classified as: foveal cystoid space at Segment 1 and no fluid at Segment 2 (n=24), parafoveal cystoid space at Segment 1 and no fluid at Segment 2 (n=25), parafoveal cystoid space at Segment 1 and diffuse fluid at Segment 2 (n=16), diffuse fluid at both segments (n=37), and diffuse fluid at both segments with subretinal fluid (n=26). Eyes with diffuse fluid at Segment 2 showed significantly poorer VA, higher ellipsoid zone disruption rates, and greater central subfield thickness than did those without fluid at Segment 2 (P<0.001 for all). These results indicate the importance of the localization and area of the fluid for VA in DME.

kn-title=Assessment of Demineralization Inhibition Effects of Dentin Desensitizers Using Swept-Source Optical Coherence Tomography
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The purpose of this study was to evaluate the mechanism of action and the inhibiting effects of two types of desensitizers against dentin demineralization using pre-demineralized hypersensitivity tooth model in vitro. In this study, we confirmed that a hypersensitivity tooth model from our preliminary experiment could be prepared by immersing dentin discs in an acetic acid-based solution with pH 5.0 for three days. Dentin discs with three days of demineralization were prepared and applied by one of the desensitizers containing calcium fluoro-alumino-silicate glass (Nanoseal, NS) or fluoro-zinc-silicate glass (Caredyne Shield, CS), followed by an additional three days of demineralization. Dentin discs for three days of demineralization (de3) and six days of demineralization (de6) without the desensitizers were also prepared. The dentin discs after the experimental protocol were scanned using swept-source optical coherence tomography (SS-OCT) to image the cross-sectional (2D) view of the samples and evaluate the SS-OCT signal. The signal intensity profiles of SS-OCT from the region of interest of 300, 500, and 700 mu m in depth were obtained to calculate the integrated signal intensity and signal attenuation coefficient. The morphological differences and remaining chemical elements of the dentin discs were also analyzed using scanning electron microscopy and energy-dispersive X-ray spectroscopy. SS-OCT images of CS and NS groups showed no obvious differences between the groups. However, SS-OCT signal profiles for both the CS and NS groups showed smaller attenuation coefficients and larger integrated signal intensities than those of the de6 group. Reactional deposits of the desensitizers even after the additional three days of demineralization were observed on the dentin surface in NS group, whereas remnants containing Zn were detected within the dentinal tubules in CS group. Consequently, both CS and NS groups showed inhibition effects against the additional three days of demineralization in this study. Our findings demonstrate that SS-OCT signal analysis can be used to monitor the dentin demineralization and inhibition effects of desensitizers against dentin demineralization in vitro.

kn-title=Evaluation of the Imaging Process for a Novel Subtraction Method Using Apparent Diffusion Coefficient Values
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Diffusion-weighted imaging may be used to obtain the apparent diffusion coefficient (ADC), which aids the diagnosis of cerebral infarction and tumors. An ADC reflects elements of free diffusion. Diffusion kurtosis imaging (DKI) has attracted attention as a restricted diffusion imaging technique. The ADC subtraction method (ASM) was developed to visualize restricted diffusion with high resolution by using two ADC maps taken with different diffusion times. We conducted the present study to provide a bridge between the reported basic ASM research and clinical research. We developed new imaging software for clinical use and evaluated its performance herein. This software performs the imaging process automatically and continuously at the pixel level, using ImageJ software. The new software uses a macro or a plugin which is compatible with various operating systems via a Java Virtual Machine. We tested the new imaging software’s performance by using a Jurkat cell bio-phantom, and the statistical evaluation of the performance clarified that the ASM values of 99.98% of the pixels in the bio-phantom and physiological saline were calculated accurately (p<0.001). The new software may serve as a useful tool for future clinical applications and restricted diffusion imaging research.

kn-title=Experimental variable effects on laser heating of inclusions during Raman spectroscopic analysis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= Raman spectroscopy for fluid, melt, and mineral inclusions provides direct insight into the physicochemical conditions of the environment surrounding the host mineral at the time of trapping. However, the obtained Raman spectral characteristics such as peak position are modified because of local temperature enhancement of the inclusions by the excitation laser, which might engender systematic errors and incorrect conclusions if the effect is not corrected. Despite the potentially non-negligible effects of laser heating, the laser heating coefficient (B) (°C/mW) of inclusions has remained unsolved. For this study, we found B from experiments and heat transport simulation to evaluate how various parameters such as experimental conditions, mineral properties, and inclusion geometry affect B of inclusions. To assess the parameters influencing laser heating, we measured B of a total of 19 CO2-rich fluid inclusions hosted in olivine, orthopyroxene, clinopyroxene, spinel, and quartz. Our results revealed that the measured B of fluid inclusions in spinel is highest (approx. 6 °C/mW) and that of quartz is lowest (approx. 1 × 10−2 °C/mW), consistent with earlier inferences. Our simulation results show that the absorption coefficient of the host mineral is correlated linearly with B. It is the most influential parameter when the absorption coefficient of the host mineral (αh) is larger than that of an inclusion (αinc). Furthermore, although our results indicate that both the inclusion size and depth have little effect on B if αh > αinc, the thickness and radius of the host mineral slightly influence B. These results suggest that the choice of inclusion size and depth to be analyzed in a given sample do not cause any systematic error in the Raman data because of laser heating, but the host radius and thickness, which can be adjusted to some degree at the time of sample preparation, can cause systematic errors between samples.Our results demonstrate that, even with laser power of 10 mW, which is typical for inclusion analysis, the inclusion temperature rises to tens or hundreds of degrees during the analysis, depending especially on the host mineral geometry and optical properties. Therefore, correction of the heating effects will be necessary to obtain reliable data from Raman spectroscopic analysis of inclusions. This paper presents some correction methods for non-negligible effects of laser heating.

kn-title=The Oldest Japanese Case of Combined Central and Peripheral Demyelination, which Developed Nine Years After the First Instance of Optic Neuritis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Combined central and peripheral demyelination (CCPD) causes demyelination in both the central and peripheral nervous systems. Anti-neurofascin 155 antibody plays an important pathogenic role in CCPD, but evidence concerning an association between this antibody and CCPD remains inconclusive. Although there have been no reports of precedent optic neuritis developing into CCPD, we herein report a Japanese man in whom optic neuritis recurred four times over nine years and who developed CCPD without positive antineurofascin 155 antibody. This case suggests the possibility of developing CCPD after optic nerve neuritis and the existence of an unknown antibody that induces CCPD.

kn-title=Direct evidence of electronic ferroelectricity in YbFe2O4 using neutron diffraction and nonlinear spectroscopy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We report the first observation of room temperature spontaneous electric polarization in an electronic ferroelectric material, a YbFe2O4 single crystal. The observation was based on second harmonic generation (SHG), a nonlinear optical process. Tensor analysis of the SHG signal revealed that this material has a polar charge superstructure with Cm symmetry. This result settles the long-term discussion on the uncertainty about electronic ferroelectric properties, including the charge order structure. We present a complete picture of the polar charge ordering of this material via consistent results from two different characterization methods. The SHG signal shows the same temperature dependence as the superlattice signal observed in neutron diffraction experiments. These results prove ferroelectric coupling to electron ordering in YbFe2O4, which results in electronic ferroelectricity which is enabled by the real space ordering of iron cations with different valences. The existence of electronic ferroelectricity holds promise for future electronics technologies where devices run a thousand times faster than frequency of the present CPU (a few gigahertz) embedded in smartphones, etc.

kn-title=Effect of rhegmatogenous retinal detachment on preoperative and postoperative retinal sensitivities
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This retrospective study investigated foveal and perifoveal retinal sensitivities using microperimetry before and after surgery for rhegmatogenous retinal detachment (RRD). Consecutive patients with RRD who underwent vitrectomy or scleral buckling were included. Comprehensive ophthalmological examinations, including microperimetry and swept-source optical coherence tomography, were performed before and 6 months after surgery. Pre- and postoperative retinal sensitivities at the fovea and 4 perifoveal measurement points farthest from the fixation point, both vertically and horizontally (superior, inferior, nasal, and temporal) were examined. A total of 34 foveal and 136 perifoveal measurement points in 34 eyes of 34 patients were evaluated. The postoperative retinal sensitivity was significantly higher than the preoperative value at foveal and perifoveal points with (P<0.001 for both) and without (fovea: P=0.005, perifovea: P<0.001) RRD. The postoperative retinal sensitivity was significantly lower at foveal (P<0.01) and perifoveal (P<0.001) points with preoperative RRD than at points without preoperative RRD; furthermore, it was significantly better at points with ellipsoid zone (Ez) continuity than at points with Ez discontinuity (fovea: P<0.01, perifovea: P<0.001). RRD deteriorates retinal sensitivity, regardless of its presence or absence at the measurement point before surgery. Postoperative Ez continuity is important for good postoperative retinal sensitivity.

kn-title=Shape analysis of rectus extraocular muscles with age and axial length using anterior segment optical coherence tomography
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Purpose</br>
This study aimed to evaluate the shape of the extraocular muscles (EOMs) in normal subjects using the en-face images of anterior segment optical coherence tomography (AS-OCT). The EOM insertion and the direction of the muscle fibers were investigated.</br> 
Subjects and methods</br>
A total of 97 healthy normal subjects (194 eyes) at Okayama University Hospital (age, 47.1±21.5 years; range, 8–79 years) participated in the study. A series of 256 tomographic images of the rectus EOMs were captured using the C-scan function of the AS-OCT (CASIA2, TOMEY Co., Japan), and the images were converted to en-face images in multi-TIFF format. The anterior chamber angle to EOM insertion distance (AID) and the angle of the muscle fibers from the insertion site (angle of muscles) were measured from the images. The correlations of AID and angle of muscles with age and axial length were investigated and evaluated.</br> 
Results</br>
AID and angle of muscles were significantly correlated with age or axial length in some EOMs. The AIDs of medial rectus (MR) (P = 0.000) and superior rectus (SR) (P = 0.005) shortened with age. The AIDs of MR (P = 0.001) and inferior rectus (IR) (P = 0.035) elongated with axial length, whereas lateral rectus (LR) (P = 0.013) shortened. The angles of MR (P = 0.001) and LR (P = 0.000) were found to have a more downward direction toward the posterior in older subjects.</br> 
Conclusion</br>
En-face images can be created by AS-OCT, and the shape of the EOMs in normal subjects using these image measurements was available. With the ability to assess the EOMs, AID and angle of muscles are expected give useful information for treating and diagnosing strabismus-related diseases.

kn-abstract=Optical coherence tomography (OCT) is an imaging technique that can visualize the internal biological structure without X-ray exposure. Swept-source OCT (SS-OCT) is one of the latest version of OCT, wherein the light source is a tunable laser that sweeps near-infrared wavelength light to achieve real-time imaging. The imaging depth of OCT is highly influenced by the translucency of the medium. The medium that does not transmit light and the deeper structure beyond the range of light penetration depth are not relevant for OCT imaging. In OCT, sound enamel is almost transparent at the OCT wavelength range, and enamel and dentin can be distinguished from each other as the dentin-enamel junction (DEJ) appears as a dark border. Demineralized enamel and dentin are imaged as bright zones because of the formation of numerous micro-porosities where the backscatter of OCT signal is increased. In cavitated caries at interproximal or occlusal hidden zone, the upper margin of the cavity reflects the signal showing a distinct bright border in the SS-OCT image. SS-OCT is capable of determining crack penetration depth even when the cracks extended beyond the DEJ. SS-OCT has a high degree of sensitivity and specificity for the detection of dental caries and tooth cracks. SS-OCT is also capable of detecting non-carious cervical lesions and occlusal tooth wear in cross-sectional views to estimate the amount of tooth structure loss.

kn-title=The role of clockwork orange in the circadian clock of the cricket Gryllus bimaculatus
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The circadian clock generates rhythms of approximately 24 h through periodic expression of the clock genes. In insects, the major clock genes period (per) and timeless (tim) are rhythmically expressed upon their transactivation by CLOCK/CYCLE, with peak levels in the early night. In Drosophila, clockwork orange (cwo) is known to inhibit the transcription of per and tim during the daytime to enhance the amplitude of the rhythm, but its function in other insects is largely unknown. In this study, we investigated the role of cwo in the clock mechanism of the cricket Gryllus bimaculatus. The results of quantitative RT-PCR showed that under a light/dark (LD) cycle, cwo is rhythmically expressed in the optic lobe (lamina-medulla complex) and peaks during the night. When cwo was knocked down via RNA interference (RNAi), some crickets lost their locomotor rhythm, while others maintained a rhythm but exhibited a longer free-running period under constant darkness (DD). In cwo(RNAi) crickets, all clock genes except for cryptochrome 2 (cry2) showed arrhythmic expression under DD; under LD, some of the clock genes showed higher mRNA levels, and tim showed rhythmic expression with a delayed phase. Based on these results, we propose that cwo plays an important role in the cricket circadian clock.

kn-title=Diagnosis of Occlusal Tooth Wear Using 3D Imaging of Optical Coherence Tomography Ex Vivo
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The aim of this study was to assess the utility of 3D imaging of optical coherence tomography (OCT) for the diagnosis of occlusal tooth wear ex vivo. Sixty-three extracted human molars with or without visible tooth wear were collected to take digital intraoral radiography and 3D OCT images. The degree of tooth wear was evaluated by 12 examiners and scored using 4-rank scale: 1-slight enamel wear; 2-distinct enamel wear; 3-tooth wear with slight dentin exposure; 4-tooth wear with distinct involvement of dentin. The degree of tooth wear was validated by the histological view of confocal laser scanning microscopy (CLSM). The sensitivity, specificity, and area under the curve (AUC) of receiver operating characteristic analysis were calculated. Diagnostic accuracy was compared with the agreement with CLSM observation using weighted kappa. The results were statistically analyzed at a significance level of alpha = 0.05. Three-dimensional OCT showed significantly higher sensitivity (p < 0.05) for all the diagnostic thresholds of enamel wear and dentin exposure than digital radiography (0.82, 0.85, and 0.79 vs. 0.56, 0.52, and 0.57, respectively). Three-dimensional OCT showed higher AUC and kappa coefficients than digital radiography (p < 0.05), where mean AUC and Kappa values were 0.95 and 0.76 for OCT and 0.92 and 0.47 for radiography, respectively. No significant difference of specificity was observed (p > 0.05). Three-dimensional OCT could visualize and estimate the degree of tooth wear and detect the dentin exposure at the tooth wear surface accurately and reproducibly. Consequently, a new guideline for tooth wear assessment can be proposed using OCT.

kn-title=Release and extraction of retained subfoveal perfluorocarbon liquid facilitated by subretinal BSS, vibration, and gravity: a case report
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background</br>
Perfluorocarbon liquid (PFCL) is an effective surgical adjuvant in performing vitrectomy for severe vitreoretinal pathologies such as proliferative vitreoretinopathy and giant retinal tears. However, subretinal retention of PFCL can occur postoperatively and retained PFCL causes severe visual disorders, particularly when PFCL was retained under the fovea. Although several procedures have been proposed for subfoveal PFCL removal, such as direct aspiration or submacular injection of balanced salt solution (BSS) to dislodge the subfoveal PFCL, the retinal damage associated with these procedures has been a major problem. Here, we report a case of subfoveal retention of PFCL for which we performed a novel surgical technique that attempts to minimize retinal damage.</br>
Case presentation</br>
A 69-year-old man presented with subfoveal retained PFCL after surgery for retinal detachment. To remove the retained PFCL, the internal limiting membrane overlying the subretinal injection site is first peeled to allow low-pressure (8 psi) transretinal BSS infusion, using a 41-gauge cannula, to slowly detach the macula. A small drainage retinotomy is created with the diathermy tip at the inferior position of the macular bleb, sized to be slightly wider than that of the PFCL droplet. The head of the bed is then raised, and the surgeon gently vibrates the patient’s head to release the PFCL droplet to allow it to migrate inferiorly towards the drainage retinotomy. The bed is returned to the horizontal position, and the PFCL, now on the retinal surface, can be aspirated. The subfoveal PFCL is removed while minimizing iatrogenic foveal and macular damage. One month after PFCL removal, the foveal structure showed partial recovery on optical coherence tomography, and BCVA improved to 20/40.</br>
Conclusion</br>
Creating a macular bleb with low infusion pressure and using vibrational forces and gravity to migrate the PFCL towards a retinotomy can be considered as a relatively atraumatic technique to remove subfoveal retained PFCL.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Optical coherence tomography (OCT) can create cross-sectional images of tooth without X-ray exposure. This study aimed to investigate the diagnostic accuracy of 3D imaging of OCT for proximal caries in posterior teeth. Thirty-six human molar teeth with 51 proximal surfaces visibly 6 intact, 16 slightly demineralized, and 29 distinct carious changes were mounted to take digital radiographs and 3D OCT images. The sensitivity, specificity and area under the receiver operating characteristic curve (AUC) for the diagnosis of enamel caries and dentin caries were calculated to quantify the diagnostic ability of 3D OCT in comparison with digital radiography. Diagnostic accuracy was evaluated by the agreement with histology using weighted Kappa. OCT showed significantly higher sensitivity, AUC and Kappa values than radiography. OCT can be a safer option for the diagnosis of proximal caries in posterior teeth that can be applied to the patients without X-ray exposure.

kn-title=Pathologically Proven Intraocular Infiltration With Adult T-Cell Leukemia/Lymphoma: Two New Cases With Either Vitreous Opacity or Aqueous Hypopyon and Literature Review of 16 Cases
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study reported 2 new patients and 16 historical cases with pathologically proven intraocular infiltration with adult T-cell leukemia and lymphoma (ATLL) to know the timing of intraocular infiltration in the disease course. The first case was a 67-year-old woman who developed bilateral vitreous opacity about half a year after the onset of acute type of ATLL that had been unresponsive to chemotherapy. She underwent vitrectomy combined with cataract surgery in both eyes. She had bilateral optic disc atrophy and localized retinal white infiltrates in both eyes. Cytological examination of vitreous aspirates demonstrated medium-sized cells with aberrant flower-like convoluted nuclei, positive for CD3, and thus indicative of T-cells. The second case was a 38-year-old man who was diagnosed acute type of ATLL at the presentation of acute kidney injury. About half a year after initial chemotherapy and allogeneic hematopoietic stem cell transplantation, he developed aqueous hypopyon in the right eye, concurrent with cutaneous and central nervous system relapse. Aqueous tap disclosed class V abnormal cells. The aqueous “pseudohypopyon” resolved in response to another round of chemotherapy with mogamulizumab. In review of 18 patients, intraocular infiltration with ATLL was diagnosed by vitrectomy in 9, aqueous tap in 3, chorioretinal biopsy in 3, and autopsy in 3. The intraocular infiltration developed concurrently with systemic diagnosis of ATLL in 5 patients, but developed later after chemotherapy in 13. In conclusion, intraocular infiltration with ATLL appears rare, and pathological diagnosis by vitrectomy and aqueous tap would help determine therapeutic plan in relapse after chemotherapy.

kn-title=Oblique Surface Dose Calculation in High-Energy X-ray Therapy
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=During radiation therapy, incident radiation oblique to the skin surface is high and may cause severe skin damage. Understanding the dose of radiation absorbed by the skin is important for predicting skin damage due to radiation. In this study, we used a high-energy (4 MV) X-ray system and an optically stimulated luminescence dosimeter (OSLD) that was developed for personal exposure dosimetry. We determined the dose variation and angular dependence, which are the characteristics of a small OSLD required to derive the calculation formula for the oblique surface dose. The dose variation was determined using the coefficient of variation. The maximum coefficient of variation for 66 small-field OSLDs was 1.71%. The angular dependence, obtained from the dose ratio of the dosimeter in the vertical direction, had a maximum value of 1.37. We derived a new equation in which the oblique surface dose can be calculated within the error range of −7.7-5.1%.

kn-title=Super-chiral vibrational spectroscopy with metasurfaces for high-sensitive identification of alanine enantiomers
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Chiral nature of an enantiomer can be characterized by circular dichroism (CD) spectroscopy, but such a technique usually suffers from weak signal even with a sophisticated optical instrument. Recent demonstrations of plasmonic metasurfaces showed that chiroptical interaction of molecules can be engineered, thereby greatly simplifying a measurement system with high sensing capability. Here, by exploiting super-chiral field in a metasurface, we experimentally demonstrate high-sensitive vibrational CD spectroscopy of alanine enantiomers, the smallest chiral amino acid. Under linearly polarized excitation, the metasurface consisting of an array of staggered Au nano-rods selectively produces the left- and right-handed super-chiral fields at 1600 cm−1, which spectrally overlaps with the functional group vibrations of alanine. In the Fourier-transform infrared spectrometer measurements, the mirror symmetric CD spectra of D- and L-alanine are clearly observed depending on the handedness of the metasurface, realizing the reliable identification of small chiral molecules. The corresponding numerical simulations reveal the underlying resonant chiroptical interaction of plasmonic modes of the metasurface and vibrational modes of alanine. Our approach demonstrates a high-sensitive vibrational CD spectroscopic technique, opening up a reliable chiral sensing platform for advanced infrared inspection technologies.

kn-title=Long-Term Control of Macular Edema With Adalimumab After Cataract Surgery in a Japanese Child With Juvenile Idiopathic Arthritis: Case Report and Review of 26 Japanese Patients
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Juvenile idiopathic arthritis-associated uveitis is rare in the Japanese population. In this article, we report a child whose macular edema was controlled for years after cataract surgery with adalimumab, and reviewed 26 Japanese patients in the literature. In this case report, a 4-year-old boy developed band keratopathy, posterior iris synechiae, and complicated cataract in both eyes. Oral prednisolone prescribed at another hospital was discontinued due to high intraocular pressure in both eyes as a steroid responder. At the age of 5 years, he started oral methotrexate 8 mg weekly for recurrent bilateral iridocyclitis and then underwent lensectomy with core vitrectomy in both eyes. Planned intraocular lens implantation was cancelled at surgery because the anterior vitreous had severe inflammatory opacity with diffuse retinal edema in both eyes. Due to persistent macular edema in both eyes 5 months postoperatively, at the age of 6 years, he began to use adalimumab injection 20 mg every 2 weeks. The macular structure depicted by optical coherence tomography became normal in 2 months. At final visit at the age of 11 years, he had the best-corrected visual acuity of 0.8 in the right eye and 0.4 in the left eye, with adalimumab 40 mg every 2 weeks and methotrexate 8 mg weekly. In conclusion, macular edema persistent despite oral methotrexate after cataract surgery could be controlled for long term by adalimumab in a child with juvenile idiopathic arthritis. In the Japanese literature, only 26 additional cases with juvenile idiopathic arthritis-associated uveitis have been reported so far.

kn-title=Microfluidic Approach to the Formation of Internally Porous Polymer Particles by Solvent Extraction
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We report the controlled formation of internally porous polyelectrolyte particles with diameters ranging from tens to hundreds of micrometers through selective solvent extraction using microfluidics. Solvent-resistant microdevices, fabricated by frontal photopolymerization, encapsulate binary polymer (P)/solvent (S1) mixtures by a carrier solvent phase (C) to form plugs with well-defined radii and low polydispersity; the suspension is then brought into contact with a selective extraction solvent (S2) that is miscible with C and S1 but not P, leading to the extraction of S1 from the droplets. The ensuing phase inversion yields polymer capsules with a smooth surface but highly porous internal structure. Depending on the liquid extraction time scale, this stage can be carried out in situ, within the chip, or ex situ, in an external S2 bath. Bimodal polymer plugs are achieved using asymmetrically inverted T junctions. For this demonstration, we form sodium poly(styrenesulfonate) (P) particles using water (S1), hexadecane (C), and methyl ethyl ketone (S2). We measure droplet extraction rates as a function of drop size and polymer concentration and propose a simple scaling model to guide particle formation. We find that the extraction time required to form particles from liquid droplets does not depend on the initial polymer concentration but is rather proportional to the initial droplet size. The resulting particle size follows a linear relationship with the initial droplet size for all polymer concentrations, allowing for the precise control of particle size. The internal particle porous structure exhibits a polymer density gradient ranging from a dense surface skin toward an essentially hollow core. Average particle porosities between 10 and 50% are achieved by varying the initial droplet compositions up to 15 wt % polymer. Such particles have potential applications in functional, optical, and coating materials.

kn-title=Superior Conjunctiva-Sparing Intraocular Lens-Suturing Technique with Straight Long Suture Needles Advanced from the Opposite Side
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background: The superior conjunctiva has to be preserved in eyes with trabeculectomy or in eyes with exfoliation glaucoma for future surgery. Under the circumstances, surgical approach for spontaneous in-the-bag intraocular lens dislocation should be limited to temporal and nasal area of the conjunctiva. A surgical technique for intraocular lens-suturing was designed to spare the superior conjunctiva.</br>
Methods: Dislocated in-the-bag intraocular lens was removed with 25G or 27G vitreous forceps from sclerocorneal incision on the temporal side after the insertion of 25G or 27G trocars with infusion cannula. A straightened long needle with 10-0 polypropylene was inserted through the sclerocorneal incision and pierced to the nasal sclera. With pulling the suture of the nasal haptic, the optic was inserted with a forceps and then the temporal haptic with polypropylene suture was pushed into the posterior chamber. The needle head of the suture tied with the temporal haptic was inserted through the sclerocorneal incision and pushed out through the limbal side port on the nasal side. The needle head was then held with a needle holder and the needle tip was pierced to the temporal sclera. The sutures were secured on the scleral surface and vitrectomy was done to confirm no retinal detachment.</br>
Results: The surgery was done in 18 eyes of 14 consecutive patients: 11 men and 3 women with the age at surgery ranging from 28 to 89 years (mean, 67 years); 4 patients in both eyes on separate occasions, 3 in the right eye, and 7 in the left eye. Predisposing factors for the dislocation were history of vitrectomy in 5 eyes of 4 patients, exfoliation in 6 eyes of 4 patients, history of uveitis in 6 eyes of 5 patients, and history of trabeculectomy in one eye of one patient. All patients had no surgical complication and gained significantly better visual acuity after the surgery (P=0.0008).</br>
Conclusion: It is technically feasible and easy to advance straight needles for intraocular lenssuturing from the opposite side on the nasal-to-temporal plane to spare the superior conjunctiva.

kn-title=Laser monitoring of dynamic behavior of magnetic nanoparticles in magnetic field gradient
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Manipulation of magnetic nanoparticles (MNP) by an external magnetic field has been widely studied in the fields of biotechnology and medicine for collecting and/or reacting biomaterials in the solutions. Here, dynamic behaviors of MNP in solution under changing gradient magnetic field were investigated using our newly developed laser transmission system (LTS) with a variable magnetic field manipulator. The manipulator consists of a moving permanent magnet placed beside the optical cell filled with MNP solution. A laser beam was focused on the cell and the transmitted laser beam was detected by a silicon photodiode, so that the localized concentration of the MNP at the focused area could be evaluated by the intensity of transmitted laser beam. In this study, the LTS was applied to evaluate dynamic behaviors of MNP in serum solution. Dispersion and aggregation of MNP in the solution were evaluated. While time evolution of dispersion depends on the serum concentration, the behavior during aggregation by the magnetic field was independent of the serum concentration. A series of measurements for zeta-potentials, distributions of particle size, and magnetization distributions was carried out to understand this difference in the behavior. The results indicated that a Brownian motion was main force to distribute the MNP in the solution; on the other hand, the magnetic force to the MNP mainly affected the behavior during aggregation of the MNP in the solution.

kn-title=Diagnosis of Occlusal Caries with Dynamic Slicing of 3D Optical Coherence Tomography Images
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Detecting the extent of occlusal caries is a clinically important but challenging task required for treatment decision making. The aim of this study was to assess the diagnostic power of 3D swept-source optical coherence tomography (OCT) for evaluation of occlusal caries in comparison with X-ray radiography. Extracted human molars not exhibiting American Dental Association (ADA) criteria advanced caries were mounted in a silicone block and digital dental radiographs were captured from the buccal side. Subsequently, occlusal surfaces were scanned with a prototype Yoshida Dental OCT. Thirteen examiners evaluated the presence and extent of caries on radiographs and dynamically sliced 3D OCT video images, using a 4 level scale-0: intact; 1: enamel demineralization without cavitation; 2: enamel caries with cavitation; 3: dentin caries with or without cavitation. Sensitivity, specificity and area under operating characteristic curves (Az) were statistically analyzed (alpha = 0.05). Reliability analysis showed an excellent agreement among the 13 examiners for both methods. The OCT presented a significantly higher sensitivity and Az value for the detection of caries compared to radiographs (p < 0.05). Radiography showed especially low sensitivity for dentin caries (0-2 versus 3). Dynamic slicing of 3D OCT volumes is a powerful adjunct tool to visual inspection to diagnose the dentin occlusal caries in vitro.

kn-title=Minimization of Amounts of Catalyst and Solvent in NHC-Catalyzed Benzoin Reactions of Solid Aldehydes: Mechanistic Consideration of Solid-to-Solid Conversion and Total Synthesis of Isodarparvinol B
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Attempts were made to minimize the amounts of catalyst and solvent in the NHC-catalyzed benzoin reactions of solid aldehydes. In some case, solid-to-solid conversions proceeded in the solvent-free NHC-catalyzed benzoin reactions. Even if a mixture of the substrate, N-heterocyclic carbene (NHC) precursor, and inorganic base was initially a powdery solid, the reaction did proceed at reaction temperature lower than the melting points of each compound. The solid mixture partially melted or became a slurry or suspension in the meantime. We call this solid/liquid mixture a semisolid state. The reaction giving an optically active product was faster than that giving a racemic mixture of the same product. Melting-point depression was observed for a series of mixtures of the substrate and product in different substrate/product ratios. Solvent-free solid-to-solid conversions were accelerated by the formation of a semisolid state resulting from the melting-point depression of the solid substrate accompanied by the product formation. In the case of solid substrates with high melting points, melting-point depression was useless, and the addition of a small amount of solvent was needed. The first total synthesis of isodarparvinol B was achieved via the NHC-catalyzed intramolecular benzoin reaction using a small amount of solvent as an additive.

kn-title=The Unlimited Potential of Microbial Rhodopsins as Optical Tools
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= Microbial rhodopsins, a photoactive membrane protein family, serve as fundamental tools for optogenetics, an innovative technology for controlling biological activities with light. Microbial rhodopsins are widely distributed in nature and have a wide variety of biological functions. Regardless of the many different known types of microbial rhodopsins, only a few of them have been used in optogenetics to control neural activity to understand neural networks. The efforts of our group have been aimed at identifying and characterizing novel rhodopsins from nature and also at engineering novel variant rhodopsins by rational design. On the basis of the molecular and functional characteristics of those novel rhodopsins, we have proposed new rhodopsin-based optogenetics tools to control not only neural activities but also "non-neural" activities. In this Perspective, we introduce the achievements and summarize future challenges in creating optogenetics tools using rhodopsins. The implementation of optogenetics deep inside an in vivo brain is the well-known challenge for existing rhodopsins. As a perspective to address this challenge, we introduce innovative optical illumination techniques using wavefront shaping that can reinforce the low light sensitivity of the rhodopsins and realize deep-brain optogenetics. The applications of our optogenetics tools could be extended to manipulate non-neural biological activities such as gene expression, apoptosis, energy production, and muscle contraction. We also discuss the potentially unlimited biotechnological applications of microbial rhodopsins in the future such as in photovoltaic devices and in drug delivery systems. We believe that advances in the field will greatly expand the potential uses of microbial rhodopsins as optical tools.

kn-title=Magnetic characterization change by solvents of magnetic nanoparticles in liquid-phase magnetic immunoassay
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Liquid-phase magnetic immunoassay (MIA) using magnetic nano-particles (MNPs) has been studied as a more rapid method compared to optical methods for inspecting proteins and viruses. MIA can estimate the number of conjugated antibodies without being washed differently from conventional optical immunoassay. However, in the case of the liquid phase, it is considered that the magnetic properties of MNPs are affected by physical properties such as viscosity and impurity substances such as biological substances contained in the blood. In this study, the effect of sodium chloride (NaCl) in buffer and serum solution was evaluated to reveal the effect of serum because the sodium (Na+) and chloride (Cl-) ions in the serum dominate ion balance of blood. The measurement results of AC magnetic susceptibility and a dynamic light scattering (DLS) showed that the aggregation of MNPs was largely affected by the concentration of NaCl. This effect of the NaCl could be explained by shielding of the surface charge of MNPs by ions in the solution. Although the concentrations of NaCl in the buffer and serum solution were almost same, we found that MNPs were aggregated more in their size for those in the serum solution because of other impurities, such as proteins. These results suggest evaluation of effects of the contaminants in serum and optimization of polymer coatings of MNPs could be important factors to realize measurements of magnetic immunoassay with high accuracy.

kn-title=The Effect of Flowable Composite Lining and Dentin Location on Microtensile Bond Strength and Internal Fracture Formation
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The objective of this study was to determine the effect of flowable composite lining and dentin location on internal dentin fracture formation in the microtensile bond strength (MTBS) test using swept-source optical coherence tomography (SS-OCT). MTBS test beams (1.0×1.0 mm) were prepared from human superficial and deep dentin, which was bonded with a self-etch adhesive (Clearfil SE Bond) and hybrid composite resin (Clearfil AP-X), with or without flowable lining (Clearfil Majesty ES-Flow). We tested 4 groups according to placement technique (with vs. without flowable liner) and dentin (superficial vs. deep) locations. Cross-sectional 2D images of the bonded interface were obtained before and after the MTBS test. Internal dentin fracture after MTBT was observed as a bright zone in SS-OCT. Flowable lining significantly reduced internal fracture formation in dentin (p<0.05). Dentin location significantly influenced MTBS (p<0.05), and this was reduced by flowable lining usage.

kn-title=Cavity Adaptation of Composite Restorations Prepared at Crown and Root: Optical Assessment Using SS-OCT
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= Evaluation of gap formation at the interfaces of a two-step self-etching adhesive with/without pre-etching was performed using sweptsource optical coherence tomography (SS-OCT). Round cavities were prepared in bovine incisors at the middle (MC) and cervical (CC) thirds of the crown and the cervical third of the root (CR). Clearfil SE bond was directly applied to one group (SE) and another (PA) was pretreated with K-etchant gel. Following restoration by flowable composite resin, the teeth were thermally challenged and stored for 2 months. Interfacial gaps observed in the cross-sectional OCT images were analyzed and the bottom cavities exhibited increased gaps compared to the margin and dentin-enamel junction (DEJ). The CR site had a larger gap than at MC and CC in the SE group. DEJ separation at the MC was significantly smaller than that at CC in both groups. Therefore, gap formation depends on the cavity region, location, and bonding protocol.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= Four new homodinuclear lanthanoid(III) dithiocarbamato (RR'dtc(-)) complexes bridged by 2,2'-bipyrimidine (bpm) of the form [{Ln(RR'dtc)(3)}(2)(mu-bpm)] {Ln = Nd or Eu; RR' = dimethyl- (Me-2) or pyrrolidine(pyr)} were prepared and their crystal structures and spectroscopic properties were characterized. The crystallographic studies revealed that all of the complexes possess a similar structural motif with an 8:8-coordination geometry, in which the bpm ligand bridges two Ln(III) centers in the kappa N-2(1,1') : kappa N-2(3,3') mode and three RR'dtc(-) ligands coordinate to each Ln(III) center. The complexes exhibit weak but relatively sharp f-f transition bands in the absorption and magnetic circular dichroism (MCD) spectra recorded in the visible region. The MCD spectral studies demonstrated the magneto-optical behavior of the complexes. The spectral features of the dithiocarbamato complexes were distinctly different from those of their beta-diketonato analogues, suggesting the coordination environment around the Ln(III) center influences the electronic structure and spectroscopic symmetry of the complexes in solution.

kn-title=Enhanced oxidative stress and the treatment by edaravone in mice model of amyotrophic lateral sclerosis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= Oxidative stress is associated with the degeneration of both motor neurons and skeletal muscles in amyotrophic lateral sclerosis (ALS). A free radical scavenger edaravone has been proven as a therapeutic drug for ALS patients, but the neuroprotective mechanism for the oxidative stress of ALS has not been fully investigated. In this study, we investigated oxidative stress in ALS model mice bearing both oxidative stress sensor nuclear erythroid 2-related factor 2 (Nrf2) and G93A-human Cu/Zn superoxide dismutase (Nrf2/G93A) treated by edaravone. In vivo Nrf2 imaging analysis showed the accelerated oxidative stress both in spinal motor neurons and lower limb muscles of Nrf2/G93A mice according to disease progression in addition to the enhancement of serum oxidative stress marker dROMS. These were significantly alleviated by edaravone treatment accompanied by clinical improvements (rotarod test). The present study suggests that in vivo optical imaging of Nrf2 is useful for detecting oxidative stress in ALS, and edaravone alleviates the degeneration of both motor neurons and muscles related to oxidative stress in ALS patients.

kn-title=Dose distribution of intensity-modulated proton therapy with and without a multi-leaf collimator for the treatment of maxillary sinus cancer: a comparative effectiveness study.

kn-abstract=BACKGROUND:
Severe complications, such as eye damage and dysfunciton of salivary glands, have been reported after radiotherapy among patients with head and neck cancer. Complications such as visual impairment have also been reported after proton therapy with pencil beam scanning (PBS). In the case of PBS, collimation can sharpen the penumbra towards surrounding normal tissue in the low energy region of the proton beam. In the current study, we examined how much the dose to the normal tissue was reduced by when intensity-modulated proton therapy (IMPT) was performed using a multi-leaf collimator (MLC) for patients with maxillary sinus cancer.<br/>
METHODS:<br/>
Computed tomography findings of 26 consecutive patients who received photon therapy at Okayama University Hospital were used in this study. We compared D2% of the region of interest (ROI; ROI-D2%) and the mean dose of ROI (ROI-mean) with and without the use of an MLC. The organs at risk (OARs) were the posterior retina, lacrimal gland, eyeball, and parotid gland. IMPT was performed for all patients. The spot size was approximately 5-6 mm at the isocenter. The collimator margin was calculated by enlarging the maximum outline of the target from the beam's eye view and setting the margin to 6 mm. All plans were optimized with the same parameters.<br/>
RESULTS:<br/>
The mean of ROI-D2% for the ipsilateral optic nerve was significantly reduced by 0.48 Gy, and the mean of ROI-mean for the ipsilateral optic nerve was significantly reduced by 1.04 Gy. The mean of ROI-mean to the optic chiasm was significantly reduced by 0.70 Gy. The dose to most OARs and the planning at risk volumes were also reduced.<br/>
CONCLUSIONS:<br/>
Compared with the plan involving IMPT without an MLC, in the dose plan involving IMPT using an MLC for maxillary sinus cancer, the dose to the optic nerve and optic chiasm were significantly reduced, as measured by the ROI-D2% and the ROI-mean. These findings demonstrate that the use of an MLC during IMPT for maxillary sinus cancer may be useful for preserving vision and preventing complications.

kn-title=Two-year Results of Intravitreal Ranibizumab Injections Using a Treat-and-extend Regimen for Macular Edema due to Branch Retinal Vein Occlusion
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= We investigated the effectiveness of a treat-and-extend regimen (TAE) of intravitreal ranibizumab injections for macular edema (ME) due to branch retinal vein occlusion (BRVO). We retrospectively examined 2-year results of 32 eyes of 32 patients who underwent TAE to treat ME due to BRVO. The patients whose treatment interval extended to ≥ 12 weeks were switched to a pro re nata regimen (PRN). For the patients whose treatment interval was <12 weeks, TAE was continued. At 2 years, 10 eyes had required no additional injections after the initial treatment period [recurrence(−) group], whereas the other 22 eyes required additional treatment [recurrence(+) group]. Among the recurrence(+) patients, 11 eyes (34.4% of total) were eventually switched from TAE to PRN; the other 11 eyes (34.4%) continued TAE for 2 years. Visual acuity and central retinal thickness were significantly improved in both the recurrence(+) and (−) groups, and there was no significant betweengroup difference in visual acuity at 2 years. Univariate analyses revealed significant differences in visual acuity (p=0.004), age (p=0.014), and vessel occlusion site (p=0.018) between these groups. Our results suggest that TAE may be effective for BRVO patients with lower visual acuity, older age, and occlusion of a major vein.

kn-title=Foveal Structural Analysis of Amblyopic Eyes with Two Types of Fixation Behavior by Spectral-Domain Optical Coherence Tomography
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= We used spectral-domain optical coherence tomography (SD-OCT) to compare the foveal and parafoveal structures of 19 subjects aged 16-58 years (8 men, 11 women): 6 amblyopic patients with eccentric fixation, 5 amblyopic patients with central fixation, and 8 visually normal controls. We obtained foveal horizontal line scans using SD-OCT on all of the patients and controls. The total and layer thicknesses at foveal areas were analyzed. The mean (SD) ages of individuals in the eccentric fixation, central fixation, and control groups were 43.0 (13.9), 42.2 (16.3), and 38.5 (15.5) years, respectively. We observed no significant differences in the foveal or parafoveal retinal thicknesses at 500 and 1,500 μm from the foveal center among the 3 groups or between the amblyopic and fellow eyes. No significant differences were observed in the thickness of the ganglion cell complex layer or outer retinal layer at 500 and 1,500 μm from the foveal center among the three groups or between the two eyes. Overall, our SD-OCT analyses revealed no characteristic structural change in foveal regions in amblyopic eyes irrespective of the fixation behavior.

kn-title=Dinuclear lanthanoid(III) dithiocarbamato complexes bridged by (E)-N-benzylidenepicolinohydrazonate: Syntheses, crystal structures and spectroscopic properties
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= (E)-N-Benzylidenepicolinohydrazide (Hbphz) was used to synthesize a series of hydrazonato-bridged homodinuclear Ln(2)(III) dithiocarbamato (RR'dtc(-)) complexes of the form [{Ln(RR' dtc)(2)}(2)(mu-bphz)(2)] {Ln= La, Pr, Nd, Sm or Eu; RR'= dimethyl-(Me-2) or pyrrolidine-(pyr)}. X-ray crystallographic studies revealed that these complexes possessed a common head-to-tail type dinuclear structural motif in which two hydrazonato ligands bridged two Ln(III) centers in the mu- 1 kappa N-2(py),O:2 kappa O-2,N(imine) mode and two RR'dtc ligands coordinated to each Ln(III) center. Interestingly, while the Sm-III and Eu-III complexes crystallized as simple 8:8-coordinate dinuclear molecules, the lighter Ln(III) (i.e. La-III, Pr-III and Nd-III) complexes afforded in some cases 9:9-coordinate molecules, where the ninth coordination site was occupied by a solvent ethanol or methanol molecule. Even for the lighter Ln(III) complexes, the complexes were solved in dichloromethane or chloroform as the 8:8-coordinate dimer, as revealed by H-1 NMR spectroscopy. In the UV-visible absorption and magnetic circular dichroism (MCD) spectra of the complexes, similar spectral patterns for ligand-centered and Laporte forbidden f-f transitions were observed. The MCD spectral studies demonstrated the characteristic magneto-optical behavior of the complexes.

kn-title=Cavernous malformation of the optic chiasm with continuous hemorrhage in a pregnant woman: A case report
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Background  Cavernous malformation of the anterior visual pathway is rare, especially in pregnant woman. Planning a treatment strategy with cross-disciplinary specialists is important. <br/>
Case description  A 27-year-old pregnant woman presented with acute hemorrhage around the right optic nerve and chiasm, manifesting as poor vision in both eyes. Examination revealed right-eye deteriorated acuity and bilateral temporal hemianopsia. Computed tomography showed an oval high-density mass in the suprasellar region. Gradient echo-based T2-weighted magnetic resonance imaging showed the lesion to be hypointense (possibly a hematoma) and mainly in the optic chiasm. Fluid attenuated inversion recovery imaging showed a bilateral optic tract surrounding the lesion, which enlarged over 1 week, increasing the loss of visual function. Five days after admission, she delivered a healthy >2500-g baby by cesarean section (CS). Right frontotemporal craniotomy was performed 7 days after CS. Incision of the right optic nerve's lateral surface revealed clotted blood with abnormal vascular construction from the right side of the chiasm. We removed the hematoma and vascular lesion. Visual evoked potentials were detected only after optic chiasm decompression. Histological evaluation revealed a hematoma-like lesion with capsules and hemosiderin deposition, suggesting cavernous malformation. Her postoperative recovery was uneventful, with right visual acuity returning to normal, and her visual field not deteriorating any more. <br/>
Conclusion  Devising a treatment strategy with the obstetrician was important in this case to manage the hematoma and cavernous malformation safely.

kn-title=Enhancement of optical force acting on vesicles via the binding of gold nanoparticles
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= Here we found that gold nanoparticles (AuNPs) enhance the optical force acting on vesicles prepared from phospholipids via hydrophobic and electrostatic interactions. A laser beam was introduced into a cuvette filled with a suspension of vesicles and it accelerated them in its propagation direction via a scattering force. The addition of the AuNPs exponentially increased the velocity of the vesicles as their concentration increased, but polystyrene particles had no significant impact on velocity in the presence of AuNPs. To elucidate the mechanism of the increased velocity, the surface charges in the vesicles and the AuNPs were controlled; the surface charges of the vesicles were varied via the use of anionic, cationic and neutral phospholipids, whereas AuNPs with positive and negative charges were synthesized by coating with citrate ion and 4-dimethylaminopyridine, respectively. All vesicles increased the velocity at different degrees depending on the surface charge. The vesicles were accelerated more efficiently when their charges were opposite those of the AuNPs. These results suggested that hydrophobic and electrostatic interactions between the vesicles and the AuNPs enhanced the optical force. By accounting for the binding constant between the vesicles and the AuNPs, we proposed a model for the relationship between the concentration of the AuNPs and the velocity of the vesicles. Consequently, the increased velocity of the vesicles was attributed to the light scattering that was enhanced when AuNPs were adsorbed onto the vesicles.

kn-title=Bipolar anodic electrochemical exfoliation of graphite powders
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The electrochemical exfoliation of graphite has attracted considerable attention as a method for large-scale, rapid production of graphene and graphene oxide (GO). As exfoliation typically requires direct electrical contact, and is limited by the shape and/or size of the starting graphite, treatment of small graphite particles and powders, the typical form available commercially, is extremely difficult. In this study, GO nanosheets were successfully prepared from small graphite particles and powders by a bipolar electrochemical process. Graphite samples were placed between two platinum feeder electrodes, and a constant current was applied between the feeder electrodes using dilute sulfuric acid as the electrolyte. Optical microscopy, atomic force microscopy, X-ray diffractometry, Raman spectroscopy, and X-ray photoelectron spectroscopy were employed to examine the samples obtained after electrolysis. The results obtained from these analyses confirmed that anodic electrochemical exfoliation occurs in the graphite samples, and the exfoliated samples are basically highly crystalline GO nanosheets with a low degree of oxidation (C/O = 3.6–5.3). This simple electrochemical method is extremely useful for preparing large amounts of graphene and GO from small particles of graphite.

en-abstract=
kn-abstract= There are two cell lineages of mammalian melanin pigment cells, one that leads to retinal pigment epithelium (RPE) cells in the eye from the optic cup and the other leading to melanocytes from vertebrate-specific neural crest cells. Melanocyte precursors have high mobility and migrate and settle into various tissues and organs, including the skin, choroid, inner ear, heart, brain, adipose tissue, lung, etc. It is well known that RPE cells are essential for visual acuity and that melanocytes in the skin provide protection against UV-damage. So, what is the function of extracutaneous melanocytes that are distributed elsewhere in the body where only very small amounts of light illuminate their existence? Here I would like to briefly introduce our research history and then discuss the important roles of melanocytes in the inner ear that are indispensable for hearing ability and those in the choroid where they seem to contribute to maintaining the structures of their habitats.

kn-title=Spin textures in condensates with large dipole moments
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= We have solved numerically the ground states of a Bose-Einstein condensate in the presence of dipolar interparticle forces using a semiclassical approach. Our motivation is to model, in particular, the spontaneous spin textures emerging in quantum gases with large dipole moments, such as Cr-52 or Dy condensates, or ultracold gases consisting of polar molecules. For a pancake-shaped harmonic ( optical) potential, we present the ground-state phase diagram spanned by the strength of the nonlinear coupling and dipolar interactions. In an elongated harmonic potential, we observe a helical spin texture. The textures calculated according to the semiclassical model in the absence of external polarizing fields are predominantly analogous to previously reported results for a ferromagnetic F = 1 spinor Bose-Einstein condensate, suggesting that the spin textures arising from the dipolar forces are largely independent of the value of the quantum number F or the origin of the dipolar interactions.

kn-title=Focusing-schlieren Visualization in A Dual-mode Scramjet
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract= Schlieren imaging is particularly suited to measuring density gradients in compressible flowfields and can be used to capture shock waves and expansion fans, as well as the turbulent structures of mixing and wake flows. Conventional schlieren imaging, however, has difficulty clearly capturing such structures in long-duration supersonic combustion test facilities. This is because the severe flow temperatures locally change the refractive index of the window glass that is being used to provide optical access. On the other hand, focusing-schlieren imaging presents the potential of reduced sensitivity to thermal distortion of the windows and to clearly capture the flow structures even during a combustion test. This reduced sensitivity is due the technique’s ability to achieve a narrow depth of focus. As part of this study, a focusing-schlieren system was developed with a depth of focus near ±5 mm and was applied to a direct-connect, continuous-flow type, supersonic combustion test facility with a stagnation temperature near 1200 K. The present system was used to successfully visualize the flowfield inside a dual-mode scramjet. The imaging system captured combustion-induced volumetric expansion of the fuel jet and an anchored bifurcated shock wave at the trailing edge of the ramp fuel injector. This is the first time successful focusing-schlieren measurements have been reported for a dual-mode scramjet.

en-abstract=
kn-abstract= Traumatic eyeball luxation is a rare clinical condition with a dramatic presentation. Here, we describe a unique case of traumatic globe luxation and complete optic nerve transection caused by heavy object compression. A 45-year-old male automobile mechanic was injured when a truck slipped from its supports, crushing his head and face. On arrival, his right eyeball was obviously displaced anteriorly and he had no light perception. Computed tomography revealed complex frontal bone and facial fractures with underlying brain contusion in addition to complete transection of the right optic nerve. The patient was successfully treated using a multidisciplinary approach.

kn-title=Histologic Evaluation of Lymphaticovenular Anastomosis Outcomes in the Rat Experimental Model: Comparison of Cases with Patency and Obstruction
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=BACKGROUND: 
Lymphaticovenular anastomosis plays an important role in the surgical treatment of lymphedema. The outcomes of lymphaticovenular anastomosis are evaluated based on changes in edema; however, isolated assessment of the anastomosis itself is difficult. The authors used an animal experimental model to conduct a detailed examination of histologic changes associated with lymphaticovenular anastomosis and determined the factors important for success. 
METHODS: 
The experimental lymphaticovenular anastomosis model was created using lumbar lymph ducts and iliolumbar veins of Wistar rats. The authors performed anastomosis under a microscope and reviewed postoperative histologic changes using optical and electron microscopy. In addition, electron microscopy and histology were used for detailed examination of the area in the vicinity of the anastomotic region in cases with patency and obstruction. 
RESULTS: 
The patency rates immediately after, 1 week after, and 1 month after lymphaticovenular anastomosis were 100 percent (20 of 20), 70 percent (14 of 20), and 65 percent, respectively. A detailed examination of the anastomotic region with electron microscopy revealed that, in cases with patency, there was no notable transformation of the endothelial cells, which formed a smooth layer. In contrast, in obstruction cases, the corresponding region of the endothelium was irregular in structure. 
CONCLUSIONS: 
Vessel obstruction after lymphaticovenular anastomosis may be associated with irregular arrangement of the endothelial layer, leading to exposure of subendothelial tissues and platelet formation. One part of the postoperative changes after anastomosis and a cause of obstruction were elucidated in this study. The authors' results may enable improvements in lymphaticovenular anastomosis by translating back to real clinical operations.

kn-abstract=Synthesis of both enantiomers of some perfume compounds, and their difference in aroma
characteristics are described. Enantiomeric pairs of methyl jasmonate and its 4,5-didehydro congener, principal components of jasmin absolute, were prepared from the corresponding commercially available racemates using lipase-catalyzed optical resolution. The E-value for the reaction is as high as 370. The nature-identical isomers produced superior aroma activity relative to unnatural ones. Racemic lavandulol from a commercial source, was also resolved using several enzymatic transesterifications followed by hydrolysis with PPL. Odor evaluation revealed that the nature-identical isomer should play a key role in lavender oil. Cis-α-irone and cis-γ-irone, used as important violet components for perfumery, were synthesized in optically active forms through fractional crystallization of the diastereomeric salts with α-phenethylamine. The nature-identical irones also had better floral characteristics like ionone.

kn-abstract=The mitochondria are involved in active and dynamic processes, such as mitochondrial biogenesis, fission, fusion and mitophagy to maintain mitochondrial and cellular functions. In obesity and type 2 diabetes, impaired oxidation, reduced mitochondrial contents, lowered rates of oxidative phosphorylation and excessive reactive oxygen species (ROS) production have been reported. Mitochondrial biogenesis is regulated by various transcription factors such as peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α), peroxisome proliferator-activated receptors (PPARs), estrogen-related receptors (ERRs), and nuclear respiratory factors (NRFs). Mitochondrial fusion is promoted by mitofusin 1 (MFN1), mitofusin 2 (MFN2) and optic atrophy 1 (OPA1), while fission is governed by the recruitment of dynamin-related protein 1 (DRP1) by adaptor proteins such as mitochondrial fission factor (MFF), mitochondrial dynamics proteins of 49 and 51 kDa (MiD49 and MiD51), and fission 1 (FIS1). Phosphatase and tensin homolog (PTEN)-induced putative kinase 1 (PINK1) and PARKIN promote DRP1-dependent mitochondrial fission, and the outer mitochondrial adaptor MiD51 is required in DRP1 recruitment and PARKIN-dependent mitophagy. This review describes the molecular mechanism of mitochondrial dynamics, its abnormality in diabetes and obesity, and pharmaceuticals targeting mitochondrial biogenesis, fission, fusion and mitophagy.

kn-title=Autopsy Case of Bilateral Optic Nerve Aplasia with Microphthalmia: Neural Retina Formation Is Required for the Coordinated Development of Ocular Tissues
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Human congenital anomalies provide information that contributes to the understanding of developmental mechanisms. Here we report bilateral optic nerve aplasia (ONA) with microphthalmia in the autopsy of the cadaver of a 70-year-old Japanese female. The gross anatomical inspection of the brain showed a cotton thread-like cord in the presumed location of the optic nerve tract or chiasm. Histologically, no neural retina, optic nerve bundle or retinal central vessels were formed in the eye globe, and the retinal pigment cells formed rosettes. The cornea, iris, and lens were also histologically abnormal. Immunohistochemically, no retinal cells expressed beta III tubulin, and Pax6-immunoreactive cells were present in the ciliary non-pigmented epithelial cells. This case of ONA could be attributed to the agenesis of retinal projection neurons as a sequel to the disruption of neural retina development. The neural retina formation would coordinate the proper development of ocular tissues.

kn-title=Metamaterial Absorbers for Infrared Detection of Molecular Self-Assembled Monolayers
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The emerging field of plasmonic metamaterials has introduced new degree of freedom to manipulate optical field from nano to macroscopic scale, offering an attractive platform for sensing applications. So far, metamaterial sensor concepts, however, have focused on hot-spot engineering to improve the near-field enhancement, rather than fully exploiting tailored material properties. Here, we present a novel spectroscopic technique based on the metamaterial infrared (IR) absorber allowing for a low-background detection scheme as well as significant plasmonic enhancement. Specifically, we experimentally demonstrate the resonant coupling of plasmonic modes of a metamaterial absorber and IR vibrational modes of a molecular self-assembled monolayer. The metamaterial consisting of an array of Au/MgF2/Au structures exhibits an anomalous absorption at ~3000 cm−1, which spectrally overlaps with C-H stretching vibrational modes. Symmetric/asymmetric C-H stretching modes of a 16-Mercaptohexadecanoic acid monolayer are clearly observed as Fano-like anti-resonance peaks within a broad plasmonic absorption of the metamaterial. Spectral analysis using Fano line-shape fitting reveals the underlying resonant interference in plasmon-molecular coupled systems. Our metamaterial approach achieves the attomole sensitivity with a large signal-to-noise ratio in the far-field measurement, thus may open up new avenues for realizing ultrasensitive IR inspection technologies.

kn-title=How far is observation allowed in patients with ectopia lentis?
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Surgical timing for ectopia lentis has not been well described until now. The purpose of this study is to find a benchmark as to how far observation would be allowed in children with ectopia lentis when they and their families are reluctant to go through surgery. Retrospective review was made on 15 consecutive patients (14 children and one adult) with ectopia lentis in both eyes, seen at a referral-based institution in 5 years from April 2008 to March 2013, to survey the reasons for continuing observation or deciding surgical intervention. The diagnoses were Marfan syndrome in six patients, familial ectopia lentis in six, and sporadic ectopia lentis in three. Observation was continued in nine patients with the age at the final visit, ranging from 4 to 17 (median 9) years, because six children had good visual acuity at both near and distant viewing with glasses, and three children had visual acuity of 0.4 at near viewing despites poor visual acuity at distant viewing with glasses. In contrast, lensectomy was determined in six patients (5 children and one adult) with the age at surgery, ranging from 4 to 36 (median 9) years, and the age at the final visit, ranging from 7 to 42 (median 11) years, mainly because of poor visual acuity at near and distant viewing. More specific causes for surgeries in five children were the optical axis to become aphakic due to the progression of ectopia in the course in two children, lens dislocation to the anterior chamber after blunt eye injury in one child, and difficulty in studying at school classes in two children. One adult patient developed cataract in ectopic lenses. Lensectomy, combined with anterior vitrectomy, was done from two limbal side ports with a 25-gauge infusion cannula and vitreous cutter. Two patients at the age of 16 and 36 years, additionally, underwent intraocular lens-suturing in both eyes. In conclusions, observation was continued in children with ectopia lentis who had good visual acuity at near viewing. The visual acuity at near viewing, 0.4 or better, would give a benchmark for continuing observation in children with ectopia lentis.

kn-title=Positioning device for outdoor mobile robots using optical sensors and lasers
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We propose a novel method for positioning a mobile robot in an outdoor environment using lasers and optical sensors. Position estimation via a noncontact optical method is useful because the information from the wheel odometer and the global positioning system in a mobile robot is unreliable in some situations. Contact optical sensors such as computer mouse are designed to be in contact with a surface and do not function well in strong ambient light conditions. To mitigate the challenges of an outdoor environment, we developed an optical device with a bandpass filter and a pipe to restrict solar light and to detect translation. The use of two devices enables sensing of the mobile robot’s position, including posture. Furthermore, employing a collimated laser beam allows measurements against a surface to be invariable with the distance to the surface. In this paper, we describe motion estimation, device configurations, and several tests for performance evaluation. We also present the experimental positioning results from a vehicle equipped with our optical device on an outdoor path. Finally, we discuss an improvement in postural accuracy by combining an optical device with precise gyroscopes.

kn-title=スカイラジオメーターとライダーを用いた岡山上空のエアロゾル観測
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=　Aerosol is one of the controlling parameter for the global climate and also effects on local health hazards. The measurement of the aerosol was originally carried out as in-situ sampling and mass weight measurement including chemical analysis. Recently, remote sensing method is applied as satellite remote sensing and surface based remote sensing. Skyradiometer and LIDAR are surface based remote sensing system. Skyradiometer measures solar radiation as direct and scattered solar radiation affected by aerosols. LIDAR emit laser beam upward and it is backscattered by overlying aerosols. The backscattered light is received by a telescope and vertical distributions of the aerosols are obtained. These measurements require atmospheric
radiation physics.
　A Skyradiometer and a LIDAR were operated continuously at Okayama University campus and aerosol parameters were obtained from both of the system. Seasonal variations of the AOT (Aerosol Optical Thickness) and Angstrom parameter (α) are evaluated. During some dust events (e.g. yellow sand and PM2.5), time variations of these parameters were identified from both of the measurement system.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We report a case of POEMS syndrome in a 20-year-old patient diagnosed after visiting an eye clinic with a chief complaint of reduced visual acuity. A male university student aged 20 years was referred to our department complaining of blurred vision in both eyes that had persisted for 1 month. He also noted headache, nausea, and paresthesia in the lower extremities around the same time. The visual acuity of his right and left eye was 20/40 and 20/20, respectively. Optic disc edema and serous retinal detachment were present. Brain magnetic resonance imaging showed no intracranial abnormalities, while elevated cerebrospinal fluid pressure, reduced nerve conduction velocity in both lower extremities, hepatosplenomegaly, M proteinemia, high blood VEGF levels, osteoblastic and osteolytic changes in the spine, and atypical plasma cells in bone lesions were noted. From the above findings, the patient was diagnosed with POEMS syndrome. He received high-dose dexamethasone, thalidomide, and radiotherapy on the sacral mass, followed by high-dose melphalan with autologous stem-cell support, and showed subsequent systemic and ophthalmologic improvement. Here, we report the youngest case ever of POEMS syndrome with ocular manifestation. If patients have optic disc edema in both eyes with no intracranial space-occupying lesion, POEMS syndrome should be considered in differential diagnosis, regardless of age.

en-abstract=　The realization of training of virtual reality is expected to prevent the accidents caused by human factor. The benefits of training in virtual environment is a realization of training in a simulated real environment. However, there is a problem that a trainee cannot train in the simulated real environment because there is no user interface （UI） to transmit the valve operations which is basic manipulation in the industrial plant to the training system.
In this study, we propose an image recognition method for developing a valve manipulation UI which aims to realize the training of valve opening manipulation in virtual environment. The method to measure the angular velocity of the circular handle of a valve utilizes the optical natural feature points obtained from the hand turning the handle. The advantage of our valve manipulation UI is that the UI can construct easily by popular products such as PC, web camera.
Our method was revealed to be able to be applied to the UI of training system for worker to train valve operating manipulation which assumed fire risk because it can measure the velocity of 22.5～90 deg/s.
kn-abstract=　人的要因の事故を防止する為，仮想現実感を利用した訓練の実現が期待されている．仮想環境での訓練の利点は実環境に近い環境で訓練できる点にある．しかし，プラント内で基本操作であるバルブの操作をシステムへ伝えるユーザ・インタフェース（UIと省略）は現在なく，実環境に即した訓練ができない問題がある．
　そこで本研究では，仮想環境におけるバルブ開操作訓練を実現するバルブ操作UI開発のため，バルブの丸ハンドルの回転速度を測定する画像認識手法を提案する．本手法はバルブの丸ハンドルを回す手から取得した光学的自然特徴点を利用する．本バルブ開操作UIはPC，Webカメラといった一般的な製品を用い平易に実現できる利点がある．
　本手法は，評価実験で22.5-90deg/sを測定できる事を確認できたため，発火危険を想定したバルブ操作訓練のためのUIに適用できる事が明らかとなった．

kn-abstract=The thermoacidophilic iron-oxidizing archaeon Acidianus brierleyi is a microorganism that could be useful in the removal of inorganic As from wastewater, because it simultaneously oxidizes As(III) and Fe(II) to As(V) and Fe(III) in an acidic culture medium, resulting in the immobilization of As(V) as FeAsO4. To investigate the oxidation mechanism, speciation of the As species in both the cells and its culture media is an important issue. Here we describe the successive determination of As(III), As(V), and total As in A. brierleyi and its culture medium via a facile method based on inductively coupled plasma–optical emission spectroscopy (ICP–OES) with a flow injection pretreatment system using a mini-column packed with an anion-exchange resin. The flow-injection pretreatment system consisted of a syringe pump, a selection valve, and a switching valve, which were controlled by a personal computer. Sample solutions with the pH adjusted to 5 were flowed into the mini-column to retain the anionic As(V), whereas As(III) was introduced into ICP–OES with no adsorption on the mini-column due to its electrically neutral form. An acidic solution (1 M HNO3) was then flowed into the mini-column to elute As(V) followed by ICP–OES measurement. The same sample was also subjected to ICP–OES without being passed through the mini-column in order to determine the total amounts of As(III) and As(V). The method was verified by comparing the results of the total As with the sum of As(III) and As(V). The calibration curves showed good linearity with limits of detection of 158, 86, and 211 ppb for As(III), As(V), and total As, respectively. The method was successfully applicable to the determination of the As species contained in the pellets of A. brierleyi and their culture media. The results suggested that the oxidation of As(III) was influenced by the presence of Fe(II) in the culture medium, i.e., Fe(II) enhanced the oxidation of As(III) in A. brierleyi. In addition, we found that no soluble As species was contained in the cell pellets and more than 60% of the As(III) in the culture medium was oxidized by A. brierleyi after a 6-day incubation.

kn-abstract=Detection and protection of apoptosis, autophagy and neurovascular unit (NVU) are essentially important in understanding and treatment for ischemic stroke patients. In this study, we have conducted an in vivo optical imaging for detecting apoptosis and activation of matrix metalloproteinases (MMPs), then evaluated the protective effect of 2 package types of free radical scavenger edaravone (A and B) on apoptosis, autophagy and NVU in mice after transient middle cerebral artery occlusion (tMCAO). As compared to vehicle treatment, edaravones A and B showed a significant improvement of clinical scores and infarct size at 48 h after 90 min of tMCAO with great reductions of in vivo fluorescent signal for MMPs and early apoptotic annexin V activations. Ex vivo imaging of MMPSense 680 or annexin V-Cy5.5 showed a fluorescent signal, while which was remarkably different between vehicle and edaravone groups, and colocalized with antibody for MMP-9 or annexin V. Edaravone A and B ameliorated the apoptotic neuronal cell death in immunohistochemistry, and activations of MMP-9 and aquaporin 4 with reducing autophagic activations of microtubule-associated protein 1 light chain 3 (LC3) in Western blot. In this study, edaravone in both packages showed a similar strong neuroprotection after cerebral ischemia, which was confirmed with in vivo and ex vivo optical imagings for MMPs and annexin V as well as reducing cerebral infarct, inhibiting apoptotic/autophagic mechanisms, and protecting a part of neurovascular unit.

kn-title=Vascularized peripheral nerve grafting promotes myelination of regrowing optic nerve
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We investigated whether the use of vascularized peripheral nerve grafts on the optic nerve stump enhances axonal regeneration of retinal ganglion cells compared with isolated nonvascularized grafts. The rat median nerve was microsurgically sutured with its supplying artery and vein to the optic nerve stump. The number of retinal ganglion cells with regenerating axons was evaluated by retrograde labeling into the grafted peripheral nerve, and the myelination of the regenerating axon fibers was examined by electron microscopy. The number of retinal ganglion cells with regenerating axons was significantly higher in the vascularized graft than in the nonvascularized graft. The ratio of myelinated axon fibers was also increased in vascularized grafts. Thus, grafting with their supplying arteries and veins to an injured nerve stump represents a promising strategy to accelerate axonal regeneration from neurons of the central nervous system.

kn-title=A New Navigation System for Minimally Invasive Total Knee Arthroplasty
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A computer-assisted navigation system to be used for total knee arthroplasties (TKAs) was reported to improve the accuracy of bone resection and result in precise implant placement, but the concomitant surgical invasion and time consumption are clinical problems. We developed a computed tomography (CT)-based navigation system (NNS) to be used for minimally invasive TKA. It requires only the reference
points from a small limited area of the medial femoral condyle and proximal tibia through a skin incision to obtain optical images. Here we evaluated the usefulness and accuracy of the NNS in comparison with the commercially available BrainLAB image-free navigation system (BLS). In a clinical experiment, the registration times obtained with the NNS tended to be shorter than those obtained with the BLS, but not significantly so. The NNS group tended to be in the extended position in the sagittal plane of the distal femur within 3 degrees, and the BLS group showed rather flexed deviation in the sagittal plane of the anterior femur.

kn-title=Molecular Aspects of Eye Evolution and Development: From the Origin of Retinal Cells to the Future of Regenerative Medicine
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A central issue of evolutionary developmental biology is how the eye is diverged morphologically and functionally. However, the unifying mechanisms or schemes that govern eye diversification remain unsolved. In this review, I first introduce the concept of evolutionary developmental biology of the eye with a focus on photoreception, the fundamental property of retinal cells. Second, I summarize the early development of vertebrate eyes and the role of a homeobox gene, Lhx1, in subdivision of the retina into 2 domains, the neural retina and retinal pigmented epithelium of the optic primordium. The 2 retinal domains are essential components of the eye as they are found in such prototypic eyes as the extant planarian eye. Finally, I propose the presence of novel retinal cell subtypes with photosensory functions based on our recent work on atypical photopigments (opsins) in vertebrates. Since human diseases are attributable to the aberration of various types of cells due to alterations in gene expression, understanding the precise mechanisms of cellular diversification and unraveling the molecular profiles of cellular subtypes are essential to future regenerative medicine.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Reactive oxygen species (ROS) are major exacerbation factor in acute ischemic stroke, and thrombolytic agent tissue plasminogen activator (tPA) may worsen motor function and cerebral infarcts. The platinum nanoparticle (nPt) is a novel ROS scavenger, and thus we examined the clinical and neuroprotective effects of nPt in ischemic mouse brains. Mice were subjected to transient middle cerebral artery occlusion (tMCAO) for 60 min and divided into the following four groups by intravenous administration upon reperfusion, vehicle, tPA, tPA + nPt, and nPt. At 48 h after tMCAO, motor function, infarct volume, immunohistochemical analyses of neurovascular unit (NVU), in vivo imaging of matrix metalloproteinase (MMP), and zymography for MMP-9 activity were examined. Superoxide anion generation at 2 h after tMCAO was also examined with hydroethidine (HEt). As a result, administration of tPA deteriorated the motor function and infarct volume as compared to vehicle. In vivo optical imaging of MMP showed strong fluorescent signals in affected regions of tMCAO groups. Immunohistochemical analyses revealed that tMCAO resulted in a minimal decrease of NAGO and occludin, but a great decrease of collagen IV and a remarkable increase of MMP-9. HEt stain showed increased ROS generation by tMCAO. All these results became pronounced with tPA administration, and were greatly reduced by nPt. The present study demonstrates that nPt treatment ameliorates neurological function and brain damage in acute cerebral infarction with neuroprotective effect on NVU and inactivation of MMP-9. The strong reduction of ROS production by nPt could account for these remarkable neurological and neuroprotective effects against ischemic stroke.

kn-abstract=The purpose of this study was to develop a series of stereoscopic anatomical images of the eye and orbit for use in the curricula of medical schools and residency programs in ophthalmology and other specialties. Layer-by-layer dissection of the eyelid, eyeball, and orbit of a cadaver was performed by an ophthalmologist. A stereoscopic camera system was used to capture a series of anatomical views that were scanned in a panoramic three-dimensional manner around the center of the lid fissure. The images could be rotated 360 degrees in the frontal plane and the angle of views could be tilted up to 90 degrees along the anteroposterior axis perpendicular to the frontal plane around the 360 degrees. The skin, orbicularis oculi muscle, and upper and lower tarsus were sequentially observed. The upper and lower eyelids were removed to expose the bulbar conjunctiva and to insert three 25-gauge trocars for vitrectomy at the location of the pars plana. The cornea was cut at the limbus, and the lens with mature cataract was dislocated. The sclera was cut to observe the trocars from inside the eyeball. The sclera was further cut to visualize the superior oblique muscle with the trochlea and the inferior oblique muscle. The eyeball was dissected completely to observe the optic nerve and the ophthalmic artery. The thin bones of the medial and inferior orbital wall were cracked with a forceps to expose the ethmoid and maxillary sinus, respectively. In conclusion, the serial dissection images visualized aspects of the local anatomy specific to various procedures, including the levator muscle and tarsus for blepharoptosis surgery, 25-gauge trocars as viewed from inside the eye globe for vitrectomy, the oblique muscles for strabismus surgery, and the thin medial and inferior orbital bony walls for orbital bone fractures.

kn-abstract=We observe adhesion sites of a cell on a substrate with high resolution. Since this observation requires interfacial measurements between the cell and the substrate, we employ scanning localized surface plasmon microscopy. We experimentally show that focal adhesion sites of a mouse muscle cell can be observed without fluorescent labeling. We also show that a non-scanning surface plasmon microscope combined with the scanning localized surface plasmon microscope contributes to observing an entire cell adhesion site and identify regions of interest.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Polymeric curved structures are widely used in imaging systems including optical fibers and microfluidic channels. Here, we demonstrate that small-scale, poly(dimethylsiloxane) (PDMS)-based, curved structures can be fabricated through controlling interfacial free energy equilibrium. Resultant structures have a smooth, symmetric, curved surface, and may be convex or concave in form based on surface tension balance. Their curvatures are controlled by surface characteristics (i.e., hydrophobicity and hydrophilicity) of the molds and semi-liquid PDMS. In addition, these structures are shown to be biocompatible for cell culture. Our system provides a simple, efficient and economical method for generating integrateable optical components without costly fabrication facilities.

en-abstract=
kn-abstract=A system for angle-resolved photoemission spectroscopy (ARPES) of small single crystals with sizes down to 100 µm has been developed. Soft X-ray synchrotron radiation with a spot size of ～40 µm × 65 µm at the sample position is used for the excitation. Using this system an ARPES measurement has been performed on a Si crystal of size 120 µm × 100 µm × 80 µm. The crystal was properly oriented on a sample stage by measuring the Laue spots. The crystal was cleaved in situ with a microcleaver at 100 K. The cleaved surface was adjusted to the beam spot using an optical microscope. Consequently, clear band dispersions along the &Gamma;-X direction reflecting the bulk electronic states were observed with a photon energy of 879 eV.

kn-title=Phase Shifts of the Circadian Locomotor Rhythm Induced by Pigment-Dispersing Factor in the Cricket Gryllus bimaculatus
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Pigment-dispersing factors (PDFs) are octadeca-peptides widely distributed in insect optic lobes and brain. In this study, we have purified PDF and determined its amino acid sequence in the cricket Gryllus bimaculatus. Its primary structure was NSEIINSLLGLPKVLNDA-NH2, homologous to other PDH family members so far reported. When injected into the optic lobe of experimentally blinded adult male crickets, Gryllus-PDF induced phase shifts in their activity rhythms in a phase dependent and dose dependent manner. The resulted phase response curve (PRC) showed delays during the late subjective night to early subjective day and advances during the mid subjective day to mid subjective night. The PRC was different in shape from those for light, serotonin and temperature. These results suggest that PDF plays a role in phase regulation of the circadian clock through a separate pathway from those of other known phase regulating agents.

Because of relatively easy access to the nervous system, the neuronal organization of the clock system in hemimetabolous insects has been studied, yielding identification of the compound eye as the major photoreceptor for entrainment and the optic lobe for the circadian clock locus. The clock site within the optic lobe is inconsistent among reported species; in cockroaches the lobula was previously thought to be a most likely clock locus but accessory medulla is recently stressed to be a clock center, while more distal part of the optic lobe including the lamina and the outer medulla area for the cricket. Identification of the clock cells needs further critical studies. Although each optic lobe clock seems functionally identical, in respect to photic entrainment and generation of the rhythm, the bilaterally paired clocks form a functional unit. They interact to produce a stable time structure within individual insects by exchanging photic and temporal information through neural pathways, in which
serotonin and pigment-dispersing factor (PDF) are involved as chemical messengers. The mutual interaction also plays an important role in seasonal adaptation of the rhythm.

kn-title=Application of Transfer Matrix Method with Signal Flow-Chart to Analyze Optical Multi-Path Ring-Resonator
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=A multi-path ring-resonator (MPRR) was proposed to extend FSR of ring resonator. However, it is complicated to analyze the MPRR by using well-known analysis techniques such as scattering matrix or other numerical methods. This paper describes procedure for deriving transfer matrix by means of signal flow-chart to analyze the MPRR. We do not need complicated calculation for steady state analysis because transfer matrix elements are formulated clearly. As a result, The calcultaion time in this method can be reduced 1/3 to 1/20 times compared with using scattering matirx method. Furthermore, a transmittance characteristics of the MPRR at FSR extension-factor of 10 will also be shown. This suggests that analysis of other types of the MPRR by using this method can be performed simply and take a shorter time.

kn-title=Comparing Optimal 3-D Reconstruction for Finite Motion and Optical Flow
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We present a theoretically optimal linear algorithm for 3-D reconstruction from point correspondences over two views. We also present a similarly constructed optimal linear algorithm for 3-D reconstruction from optical flow. We then compare the performance of the two algorithms by simulation and real-image experiments using the same data. This is the first impartial comparison ever done in the sense that the two algorithms are both optimal, extracting the information contained in the data to a maximum possible degree. We observe that the finite motion solution is always superior to the optical flow solution and conclude
that the finite motion algorithm should be used for 3-D reconstruction.

kn-title=Consideration on the Correlation between Basicity of Oxide Glasses and O1s Chemical Shift in XPS
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=O1s binding energy measured by X-ray photoelectron spectroscopy (XPS) is candidate as a new tool to determine a new scale of Lewis basicity of oxide ions in glass. Some mathematical expressions for the basicity or XPS chemical shift, such as charge parameter and optical basicity, were compared with the experimental O1s binding energy in binary alkali oxide glasses. The expressions so far in use needed some modification in parameters. A new empirical expression introduced in this paper gives a new concept and universal scale of basicity.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=An 18-year-old woman with a 2-year history of hypertension and headache was diagnosed with noradrenalin-secreting bilateral adrenal pheochromocytomas with paragangliomas in the background of von Hippel-Lindau disease with family histories and a missense mutation, 712C to T (Arg167Trp) in the VHL gene. She had optic disc hemangioma in the left eye which gradually enlarged and caused serous retinal detachment on the macula in one year. Low-dose external beam radiation (20 Gy) was administered to the left eye using a lens-sparing single lateral technique. She underwent craniotomy for cerebellar hemangioblastoma at the age of 22 years and total pancreatectomy for multiple neuroendocrine tumors at the age of 24 years. In the 6-year follow-up period after the radiotherapy, the optic disc hemangioma gradually reduced in size and its activity remained low, allowing good central vision to be maintained. External beam radiation is recommended as a treatment option for the initial therapy for optic disc hemangioma.

kn-abstract=All of the rats were enuculated one of the eyes, and then trained to perfect discrimination in the box manufactured following to M.F. Fritz's opinion. Nextly they were subjected to subcortical injury; -especially our experiments were directed toward the effect of thalamic lesions of the half, -before relearning the habit. The brains were then prepared for sektioning. A macroscopic estimation of the amount of injury was made and microscopic study, too. From these sections we have estimated the depth of injury in each animals and the degree of fiber tract degenerations. The subcortical injury which was given opposite to the healthy eye, abolishes all reactions to discrete visual object, but does not interfer with the formation of the reaction to the light versus darkness, and which was given same to the healthy eye does not, mostly, affect all reactions to them. These experiments does not decide to completely, but it may be conceivable that optic-nerves semicross at the optic-nerves acrossing part, and non-cross fibers are very few.

kn-title=コルポスコピー(Kolposkopie)による産婦人科領域非癌性疾患の観察並びにその組織学的所見に就いて
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Colposcopy, being introduced by H. Hinselmann in 1925, has developed chiefly in the field of early diagnosis of cervical carcinoma, and nowadays it may be said that the use is almost confined to this sole subject. Even in Germany and Australia where colposcopic examination has been accepted as an efficacious diagnostic method and is prevailing in general practice, paper dealing with non-carcinomatous diseases is minimum. Picture seen through colposcope is entirely specific and quite different from that by naked-eye examination, so it is not useless to observe and record the magnified picture of the non-carcinomatous diseases. I tried to evaluate the diagnostic efficacy of colposcopy, especially in non-carcinomatous diseases, observing whether any specific finding may be found or not. Method:
550 cases of out-patients of our clinic, from Dec. 1956 to Aug. 1957, were examined through Hinselmann's colposcope of Möller Optical Works of Germany, Colpophotography in selected cases and biopsy to all cases were carried out too, and the colposcopic findings were identified by the histologic findings in every case for the purpose of interpretation of colposcopic picture.
Results and Conclusion: 1) At the second healing stage of erosion, R. Meyer claims “overgrowth” and Fischer-Wasels advanced “squamous metaplasia”. I performed serial section biopsy to 9 blocks of specimen removed from the beginning Nabothian follicles and in 4 blocks, overgrowth, and in 1 block, squamous metaplasia were found. From the results obtained, I conclude that Nabothian follicle may be produced by squamous metaplasia as well as by overgrowth. 2) Among the 402 cases of cervical erosion (bleeding group 108 cases and non-bleeding group 294 cases), nearly one half of the bleeding group and 1/3 of the non-bleeding group were true erosion. Through the entire cases, the incidenee of misdiagnosis was 1.6% (5 cases), but not any specific finding was noted colposcopically. Carcinoma was detected in 10 cases (2.4%) of innocent-looking erosion. If the colposcopic examination is performed as a screening test prior to the beginning of erosio-treatment it may be useful to determine more appropriate therapy to every case. 3) Examining 17 functional bleeding cases colposcopically, 6 cases were acknowledged to be functional, considering the manner of bleeding, history and menstrual cycle etc. In some cases of irregular genital bleeding, the site or, although not always, even the cause of bleeding may be clarified easily by colposcopic examination. 4) Colpitis: no specific finding was found colposcopically, but, examining 61 cases, 18 cases proved to be misdiagnosis and even in 1 case, the entity proved to be carcinomatous. 5) In 22 adnexitis cases, 1 cervical tuberculosis case and 23 primary sterility cases, no pathognomonic finding was found. It must call our attention, however, that in chronic adnexitis and in primary sterility cases, remnant of inflammatory process was quite common. 6) Observing 28 cases of "Erosio gravidarum", it was noted that the remarkable increase of vaginal discharge during pregnancy was due to the marked proliferation of cervical epithelium (colposcopically; ectopy) and also that, in order to avoid histological misdiagnosis, the case history and clinical findings must be refered to. 7) The green color filter, which has been used to observe the fine structure of small vessels, is useful too in discovery of beginning transition zone. 8) Examining 191 cases of patients with the chief complaint of genital discharge, 118 cases proved to be noninflammatory and 2 cases were suffering from postabortive endometritis. Colposcope is useful to follow-up of healing process of the lower genital lesions, such as cauterization therapy, and it may be accepted widely as an useful instrument in the near future.

kn-abstract=I have examined 57 cases of the uterine cervical cancer and 2 cases of the normal uterine cervix (non-pregnant and pregnant) with electron microscope. 1) Normal uterine cervix. The nucleocytoplasmic ratio becomes lower, and mitochondria a fewer from the profundal layer to the superficial one. The intercellular bridge develops in superficial spinal layer highly, and the cytoplasmic communication may be seen at one part of bridge. The tonofibrils of neighbouring cells don't connect with each other, and they make themselves into a bundle in the intercellular bridge and build the Bizozzero's node described by Porter and Takaki. But the situation and relationship of the Biyozzero's node in the bridge don't quite accord with their opinions. During pregnancy the cytoplasm of superficial layer is rather granular than fibrous, and characteristic intercellular sinus may also be recognized. 2) Carcinoma of the cervix. The structure of cellular border is simple in the epidermoid carcinoma. The mitochondia, endoplasmic reticulnm and Golgi body are observed in the cytoplasm. Although there is no statistical significancy, inclusion bodies have tendency to increase by radiation. The nuclear membrane is double layered, but doesn't look such thickening as observed with optical microscope. The onucleoplasm is composed of fine granules which become coarse or nodular by degeneration. The nucleoli have no definite form.
They consist of highly electron dense particles and possess no limiting membranes. There are many mitotic figures in cancer cells. The cell, on the whole, revealed 3 stratified structure in the prophase, and 2 stratified one in the metaphase. In the adenocarcinoma, I notice the characteristic findings that have many vacuoles and lipid or secretory granules in its cytoplasm. 3) Autolytic changes of cervical cancer.
The extirpated cancer tissue shows remarkable changes within 40 minutes in 20°C normal saline solution. 4) Changes of cancer cells incident to radiation. The radiative change differs from the autolytic one in quantity and duration. The fatty and vacuolar degeneration, giant cell and inclusion body appear in the radiation newly, but not in the autolysis. There is no essential difference between x-ray and radium about the effect. The mitochondrias are the first to suffer from radiation, but the nuclear and the cell membrane are the last to change. As the radiative changes, the thickening of nuclear membrane, vacuolar degeneration and congregated picture of nucleoplasm are hardly seen in the electron microscopy, but not rarely in the optical one. 5) Relationship of radiosensitivity of uterine cervical carcinoma to histopathological picture and clinical findings. The spindle type is more radiosensitive than the transitional and spinal one. Especially the significant difference was recognized between the spindle and the transitional. The high density of cancer cells is more sensitive than the low significantly. But the radiosensitivity has no significant relation with Imai's C. P. L. classification and the other clinical findings. About the radiosensitivity, the electron microscopical findings accord with the optical one relatively.

kn-abstract=Realizing that the optical density of phosphate buffer suspensions of E. coli and Aerobacter aerogenes, Sal. typhi 57S and 57R, Staphylococcus aureus and albus at the wave length of 537 mμ changes at the time of glucose metabolism, changes of viscosity, viable counts, and the changes in the volumes of proteins, ribonucleic acid, desoxyribonucleic acid composing bacteria have been pursued and the results are as follows. 1. During the glucose metabolism of buffer suspensions using the bacteria mentioned above a rise of optical density can be observsd and the rise has usually a parallel concern with time incubated. 2. Accompanying the rise of the optical density the increase in the relative viscosity and increase of ribonucleic acid and proteins can be recognized. Assimilation and synthetic action can also be seen during the glucose metabolism. Changes of optical density have been found to be inhibited by antibiotics and thus this factor has been utilized in simple examination of antibiotics.

kn-abstract=Several surgical attacks have recently been carried out for Parkinsonism. In 1954, J. Browder reported improvement in Parkinsonism by occulusion of the anterior chorioidal artery, but it was not obvious what was the effective mechanism of the therapy. Therfore, the auther tried to solve the problem and the following results habe been obtained. Cat was used for experimental study. After the injection of gelatin India-ink into the anterior chorioidal artery, the area of its distribution was determined by microscopy of the specimens of serial section. The most common area was as follows: 1. A part of Tractus optics. 2. Capsula interna (posterior to Nucleus praethl. ant.) 3. About the half of Globus pallidus (posterior to Nucleus praethl. ant.) 4. Nucleus amygdalae (about the medial two-thirds). 5. Cornus ammonis. 6. Lobus piriformis. 7. Plexus chorioidea. 8. A part of Ganglion geniculatum laterale, a part of Radiatio optica, and a part of thalamus. Thus, there is almost no difference between the blood supply of the anterior chorioidal artery of man and that of cats.

kn-abstract=Morphological studies on the ciliary muscles, lamina vitrea and ciliary vessels were made, and the results are as follows: 1. Fine fibrils and nuclei were seen in the inner sheet of the lamina vitrea. Therfore the inner sheet is not structureless, as it is generally considerd, but a fibrous membrane. 2. When the ciliary muscles contract the lamina vitrea puts pressure on the vitreous, so that the anterior chamber becomes narrow, and aquious outflow is improved. 3. When the ciliary muscles contract, the ciliary body becomes congestiv and the aquious humor is more produced. 4. When the lamina vitrea is pulled forward by the contraction of the ciliary muscles, the compression of the visual cells takes place, and anemia of the coroidal vessels occurs near the optic nerve head, so the blind sport expands.

en-title=Effects of Interface Activating Reagents on the Diazo Reaction of Bilirubin Part 1. Effect of Interface Activating Reagents on Bilirubin

en-abstract=
kn-abstract=Selecting solvent that dissolves interface activating reagents and bilirubin dimethylester relatively well and dissolving each of them the author prepared an interface active bilirubin-dimethylester aqueous solution. Then evaqorating this solution at 80°C under a lolw pressure, the auther studied the chemical proqerties of the vaqor dissolved in water and compare with the proqerties of bilirubin. The following are the results of this comparative study. 1. Each interface activating reagent possesses the specific capacity to dissolve bilirubin-dimethlyester in water, and there is a direct-proportion relationship between the quantity of bilirubin dimethylester dissolved in water and quantiy of activating reagent required for the dissolution. The bilirubindimethylester dissolving capacity of each reagent is 1.5 to 4.0 times the bilirubin dissolving capacity. 2. The absorption curve of the bilirubin-dimethylester aquoeus solution has its maximum at 420 mμ, and with the increase in the quantity of the activation reagent added, the maximum absorption curve moves 5-10 mμ towards the long side of short wave. However, in the case of non-ionic activating reagent hardly any such change occurs. 3. The bilirubin-dimethylester aqueous solution is always positive to the direct diazo reaction, and its sensitivity to diazo is not affected by the quantity of activating reagent but is fixed. 4. About 50-75 per cent diazo reaction of the bilirubidimethylester aqueous solution is completed within 5 minutes, but it requires about 40 minutes for its completion. 5. Spectroscopically there is no great difference between bilirubin-dimethylester azo and bilirubin azo, but the optical desnity at 490 mμ on the long side of short wave is higher in the former.

kn-abstract=By selecting the solvent that dissolves interface activating reagents and bilirubin relatively well and after dissolving each the author prepared an interface activ bilirubin aqueous solution. This solution was evaporated at 80°C under a low pressure and the solubility in water and the chemical properties of the vapor were studied; and the following ressults were obtained. 1. Each interface activation reagent possesses its own specific capacity to dissolve bilirubin in water, and there is almost a direct-proportion relation between the quantity of bilirubin dissolved in water and the quantity of activating reagent required for such a dissolution. 2. The absorption curve of the bilirubin aqueous solution shows its maximum at 450 mμ, and with the increase in the quantity of the loaded activating reagent the absorption maximum moves 5-10 mμ towards the long side of the short wave; but in the case using non-ionic reagent the absorption maximum remains almost unchanged. 3. The bilirubin aqueous solution is positive to the direct diazo reaction, and its sensitivity to the diazo reaction is proportional to the quantity of the activating reagent added, making the maximum sensitvity to the diazo reaction stable beyond a given quantity. Therefore, the dissolution of bilirubin in water by the aid of the interface activating reagent and the positivity to the diazo reaction are two different phenomena. Thus it is impossible to say that the dissolution of bilirubin in water make it positive to the direct diazo reaction. 4. The bilirubin aqueous solution by the aid of interface activating reagent required 40 to 60 minutes for the completion of diazo reaction and the production of azo dye is about directly proportional to the time required for its production. 5. The absorption maximum of azo dye produced the diazo reaction always at 530 mμ even when pH of the solvent is changed, and the optical density increases proportionately to the strength of acidity. At the same pH the optical density at 530 mμ of azo dye produced by ionic activating reagent is higher than that of the azo dye produced by non-ionic activating reagent; whereas the optical density of 470 mμ on the long side of short wave, on the contrary, of the azo dye produced by non-ionic activating reagent is higher.

kn-abstract=The congenital absence of corpus callosum has been recently found to occur among some mice of the ddN strain in our laboratory. In this experiment, the differences of the visual evoked potentials among the normal corpus callosum, callosal hypogenesis and agenesis in ddN strain mice were investigated. One-Hz- flash stimulations were given on the left eye through a glass fiber connector from the EEG stimulator. Under Nembutal anesthesia, two hundred times of average evoked field potentials were recorded from the contralateral and ipsilateral visual cortices. Electrophysiologically, the normal mice showed complete decussation on the opic chiasm. On the other hand, the complete acallosal mice could be classified into two types, such as those of complete decussation and those of absence of optic chiasm. In the complete decussation of acallosal mice, the latency, peak latency and duration of these potentials from ipsilateral side significantly prolonged, and the amplitude of the potentials extremely diminished. In the absence of optic chiasm of complete acallosal mice, the potentials were obtained only in ipsilateral cortex. After amputation of the corpus callosum in the normal mice, the visual evoked field potential showed similar to acallosal mice. However, in the hypogenesis of corpus callosum, there was no significant difference in the potentials compared with the normal mice.

en-abstract=
kn-abstract=PURPOSE: Circumscribed choroidal hemangioma is an uncommon, benign vascular tumor that typically appears in the posterior pole of the eye. Visual acuity loss typically results from its exudation, followed by serous retinal detachment. The purpose of the study was to evaluate the efficacy and the safety of external beam irradiation in treating circumscribed choroidal hemangioma. METHODS: We treated 4 eyes of 4 patients with circumscribed choroidal hemangioma with external beam irradiation at Okayama University Hospital from 2002 to 2009. A total absorbed dose of 20 Gy (beam energy, 4, 10 MV) was applied to each of the 4 patients. Each patient received a single 2-Gy daily fraction for five consecutive days in a week, for two consecutive weeks. RESULTS: In all cases, the retinal detachment showed complete resolution within 8 to 48 days after treatment. A decrease in tumor thickness was observed in all cases except one in which the follow-up period was rather short (3.7 months). The visual acuity improved in all 4 eyes. No eyes showed deterioration of visual acuity. During follow-up periods of 3.7 months to 58.5 months, there were no signs of radiation-induced cataract, retinopathy or optic neuropathy.

kn-abstract=Preliminary experiments on the accuracy of quantitative microprobe analysis for the instrument set in the Institute for Themal Spring Research, Okayama University were carried out. Dead time of the instrument ranged about 5.5-5.6 microsecond, which delayed 1.5 microsecond than
usual value. Bombarding by finely focused electron beam, intensities of the characteristic X-ray of alkali metal such as NaKα and KKα decreased drastically in five to ten minutes.
Intensities of the characteristic X-ray decreased
in relation to the degree of off-focusing, when the spectrometer fixed at optically focused position. Readjusting of spectrometer after every move of sample was indispensable for the proof of accurate intensities. Applying BENCE and ALBEE'S correction method, empirical a factors was approved of preferable for quantitative analyses of silicates than calculated α factors.

kn-abstract=<p>We study properties of excited states of an array of weakly coupled quasi-two-dimensional Bose condensates by using the hydrodynamic theory. The spectrum of the axial excited states strongly depends on the coupling among the various discrete radial modes in a given symmetry. By including mode coupling within a given symmetry, the complete excitation spectrum of axial quasiparticles with various discrete radial nodes are presented. A single parameter which determines the strength of the mode coupling is identified. The excitation spectrum in the zero angular momentum sector can be observed by using the Bragg scattering experiments.</p>

An absorption spectrum of a uniform Sn plasma generated by thermal x rays has been measured in the EUV range (9-19 nm wavelength) for the first time. Experimental results indicate that control of the optical depth of the laser-produced Sn plasma is essential for obtaining high conversion to 13.5 nm-wavelength EUV radiation; 1.8% of the conversion efficiency was attained with the use of 2.2 ns laser pulses.</p>

kn-title=Optical-drop wavelength assignment problem for wavelength reuse in WDM ring metropolitan area networks
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This paper presents a formulation of the optical-drop wavelength assignment problem (ODWAP) and its heuristic algorithm for WDM ring networks. The wavelength-division multiplexing (WDM) technology has been popular in communication societies for providing very large communication bands by multiple lightpaths with different wavelengths on a single optical fiber. Particularly, a double-ring optical network architecture based on the packet-over-WDM technology such as the HORNET architecture has been studied as a next generation platform for metropolitan area networks (MANs). Each node in this architecture is equipped with a wavelength-fixed optical-drop and a tunable transmitter so that a lightpath can be established between any pair of nodes without wavelength conversions. In this paper, we formulate ODWAP for efficient wavelength reuse under heterogeneous traffic in this network. Then, we propose a simple heuristic algorithm for ODWAP. Through extensive simulations, we demonstrate the effectiveness of our approach in reducing waiting times for packet transmissions when a small number of wavelengths are available to retain the network cost for MANs.

kn-title=Regular boundary integral formulation for the analysis of open dielectric/optical waveguides
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=<p>A regular boundary element method is employed for the variational formulation of the Helmholtz equation that governs waveguiding problems. The problems are defined on the boundary as usual, but as in the charge simulation method, the source points associated with the fundamental solutions are allocated outside the domain so that the singular integrals which occur in the standard boundary element procedure can be avoided. First, the formulation is developed for the two-dimensional (2-D) scalar Helmholtz problem, solving for the axial components of either electric or magnetic fields. Then the formulation is extended for the analysis of dielectric waveguides of the open type incorporating axial components of both electric and magnetic fields, for the solution of the propagating modes which are generally of hybrid types. Very close agreements have been found when the solutions obtained by the present formulation are compared with the ones obtained by different methods. One merit of the extended formulation is that it has been fixed to suppress the spurious solutions </p>

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=<p>A monoclonal antibody (IgG) that recognizes a 53-kDa zebrafishnext brain protein was isolated and used to characterize the distribution of this protein in zebrafish.next (1) The antigen was found only in the brain and not in any other tissues such as muscle, dermis and cartilage. Within the brain, the antibody recognized extracellular matrix (ECM) outside neuronal cells. (2) Digestion by hyaluronidase released the antigen from brain tissue, and the monoclonal antibody staining was also decreased by the digestion by hyaluronidase. (3) The pattern of antigen distribution is not perineuronal, as the density of the antigen at the periphery of the cells was practically identical to that of the empty intercellular spaces. Therefore, this monoclonal antibody does not recognize the perineuronal glycocortex. (4) The antigen is distributed only in limited areas of the brain, namely in the periphery of the forebrain, the hypothalamus, the optic tectum, the interpeduncular nucleus, the cerebellum and the ventricular rim of the medulla. In the optic tectum, the antibody strongly stained the most superficial layer, and in the cerebellum, it stained the molecular but not the granular layer. These patterns of distribution are very different from those of other typical brain ECM proteins and suggest that this protein may play quite distinct roles in brain development and maintenance.</p>

kn-title=Hatching controlled by the circatidal clock, and the role of the medulla terminalis in the optic peduncle of the eyestalk, in an estuarine crab Sesarma haematocheir

kn-abstract=Embryos attached to the female crab Sesarma
haematocheir hatch synchronously within 1 h. Hatching is also synchronized near the time of the expected nocturnal high tide. These events are governed by a single circatidal clock (or pacemaker) in the female crab. The present
study examined the role of the optic peduncle of the eyestalk on hatching and hatching synchrony. Surgery was performed either from the tip of the eyestalk [to remove the region of the optic peduncle from the compound eye–retina complex to the medulla interna (MI)] or from a small triangle 'window' opened on the eyestalk exoskeleton [to create lesions on the medulla
terminalis (MT) of the optic peduncle]. Neither hatching nor hatching synchrony was affected by removal of the region of the optic peduncle from the compound eye–retina complex to the MI: the circatidal rhythm also remained. Removal of the MI probably caused damage to the sinus gland and the bundle of axons running from the sinus gland to the X organ. Nevertheless, maintenance of
highly synchronized hatching indicates that the X
organ–sinus gland system is not related to hatching. Hatching and hatching synchrony were not affected by dorsal-half cuts of the MT: the timing of hatching was not affected either. By contrast, transverse and ventral-half cuts of the MT caused severe damage to most females;
hatching of many females was suppressed, while hatching of some females was either periodic, at intervals of approximately 24 h, or arrhythmic for a few days. The bundle of neuronal axons is tangled in the MT, and the axons inducing hatching pass through the ventral half of
the MT. Complete incision of these axon bundles may have suppressed hatching. Incomplete incision of the axon bundle or partial damage to the neurons may have caused periodic or arrhythmic patterns of hatching. There are
two possible roles for MT in hatching. One possibility is that neurons in the MT only induce hatching under the control of the circatidal pacemaker located in a site
somewhere other than the optic peduncle. Another
possibility is that the circatidal pacemaker is actually present in the MT. The second possibility seems more plausible. Each embryo has a special 48–49.5 h developmental program for hatching. This program could be initiated by the circatidal pacemaker in the female, and
hatching synchrony may also be enhanced by the same pacemaker.

kn-title=Three-dimensional shape measurement of a transparent object using a rangefinding approach
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=<p>This paper describes a non-contact optical measuring approach by which to measure the three-dimensional (3D) shape of a transparent object such as a glass panel or an acrylic plate. In conventional approaches to obtain the 3D shape of a transparent object, contact-type sensors have been widely used. However, the measurement accuracy of contact-type sensors is susceptible to the influence of various factors. In this paper, we propose a novel triangulation-based rangefinding approach that can be applied to the 3D shape of a transparent object or to an opaque object. The rangefinder is based on the fact that the light projected onto the surface of a transparent object is in part reflected by the surface, though the majority of the projected light is transmitted through the surface. From the experimental results, the proposed rangefinding approach has the advantage that it can easily measure the 3D-shape of an object if the object reflects or transmits light, depending on its location. As a result, we conclude that the proposed approach has great potential for a wide range of industrial applications.</p>

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=<p>Since practical multiplexed structured light systems currently available use plural light patterns or different illumination conditions to ensure a high reliability, their fast performance is impaired. This paper describes a fast, highly reliable range imaging system with a multiplexed structured light system that uses a direct space encoding approach while using only a single light pattern. Unlike a conventional encoding approach, the proposed approach is unique in that it encodes object space through the use of a special optical system which consists of field stops, plural lenses, and shield masks, rather than a light pattern. The theoretical considerations and experimental results demonstrate that the proposed approach is effective for a highly reliable, fast, accurate range imaging system </p>

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=<p>2-Mercaptoethanol increases the optical density of assay solutions at wavelengths between 280 to 400 nm, and therefore interferes with the measurement of protein concentration by the microbiuret method. Protein concentration can be determined in the presence of 2-mercaptoethanol up to 6 mM by modification of the method as follows: after the precipitation of protein by trichloroacetic acid in the presence of deoxycholate, the precipitate is resolubilized with NaOH solution. Dithiothreitol interfered with the protein determinations could by made in the presence of 4 mM of dithiothreitol with the modified microbiuret method. This modified method is time-saving and more reliable than other methods for protein determination, such as Lowry's method, in the presence of sulfhydryl reagents.</p>

kn-title=Physiological Studies on Pupillary Reaction
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=1. The excitability of the different parts of the retina for the Pupillary reflex movement was examined with Hess's differential pupilloscope. 2. The consensual reaction is observed in man, cats, and dogs, but found neither in those animals whose optic fibres decussate perfectly in the chiasma,-for example, guinea-pig, nor in those animals which have non-decussate fibres not running to the superior colliculus, - for example, rabbits, rats, and goats. 3. The so-called Gudden's pupillary fibres are identical with the optic fibres themselves, but their nerve fibres are nothing but the special optic fibres which run to the superior colliculus. 4. The pupillary movement does not attend to the accomodation of the eye itself, but convergence of the visual axes. 5. A new scheme of the nervous connection for the pupillary reflex movement which explains all facts known without contradiction is advanced by the author.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=<p>Ferric nitrilotriacetate (Fe3+-NTA) solution showed maximum absorbance at pH 7.5. The iron was in ferric high-spin state and coordinated octahedrally with a relatively symmetric structure and also probably pentagonally. A spin trapping technique employing 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) yielded a DMPO spin adduct of unknown radical with three doublets (DMPO-Z) and a simple nitroxide radical (Y-NO.) in serum from rats injected intraperitoneally with Fe3+-NTA. When the Fe3+-NTA solution was diluted 500-fold with 50 mM NTA solution, DMPO-Z, Y-NO. and an additional signal, DMPO-OH were observed. The DMPO-Z signal was suppressed by a decrease in oxygen tension, alpha-tocopherol and 3-tert-butyl-4-hydroxy-anisole (BHA). The DMPO-OH signal was suppressed in the presence of ethanol and catalase. Fe2+-NTA solution hardly produced DMPO spin adducts. The Fe3+-NTA solution produced a strong DMPO-OH signal in the presence of H2O2. Rose Bengal solution, a singlet oxygen generating system, produced the same DMPO adducts. Fe3+-NTA reacted with oxygen in solution. The oxygen was activated and might be similar to singlet molecular oxygen. In the presence of H2O2, the Fe3+-NTA solution generated a hydroxyl radical. Fe3+-NTA itself generated free radicals, but Fe2+-NTA did not.</p>

kn-title=Can Narrow-band Imaging Be Used to Determine the Surgical Margin of Superficial Hypopharyngeal Cancer?
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=<p>Narrow-band imaging (NBI) is a novel optical technique that uses narrow bandwidth filters in a video endoscope system to improve the diagnostic capability of endoscopes in characterizing tissues. It is well known that early identification of neoplasia in the gastrointestinal tract using this technique might make it possible to reduce the suffering of patients caused by loss of function or severe complications after radical surgery. Several reports have introduced this system as a preoperative examination to evaluate the lateral spread of the neoplastic lesions in the oropharynx or hypopharynx. We experienced a case with hypopharyngeal cancer in which we were able to avoid underestimating cancer lesions following insufficient resection using the NBI system. A 62-year-old female underwent partial hypopharyngectomy with the margin estimated by an NBI view coupled with reconstruction of the hypopharynx while preserving the larynx. The resected specimen was cut into serial sections for a detailed pathology examination. The surgical margin seemed to be wide enough and it could be assumed that if possible we should observe these cancers with conventional electroendoscopy and NBI before treatment.</p>

kn-title=Visualization of intrathoracically disseminated solid tumors in mice with optical imaging by telomerase-specific amplification of a transferred green fluorescent protein gene
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=Currently available methods for detection of tumors in vivo such as X-ray, computed tomography, and ultrasonography are noninvasive and have been well studied; the images, however, are not specific for tumors. Direct optical imaging of tumor cells in vivo that can clearly distinguish them from surrounding normal tissues may be clinically useful. Here, we describe a new approach to visualizing tumors whose fluorescence can be detected using tumor-specific replication-competent adenovirus (OBP-301, Telomelysin) in combination with Ad-GFP, a replication-deficient adenovirus expressing green fluorescent protein (GFP). Human telomerase reverse transcriptase is the catalytic subunit of telomerase, which is highly active in cancer cells but quiescent in most normal somatic cells. We constructed an adenovirus 5 vector in which the human telomerase reverse transcriptase promoter element drives expression of E1A and E1B genes linked with an internal ribosome entry site and showed that OBP-301 replicated efficiently in human cancer cells, but not in normal cells such as human fibroblasts. When the human lung and colon cancer cell lines were infected with Ad-GFP at a low multiplicity of infection, GFP expression could not be detected under a fluorescence microscope; in the presence of OBP-301, however, Ad-GFP replicated in these tumor cells and showed strong green signals. In contrast, coinfection with OBP-301 and Ad-GFP did not show any signals in normal cells such as fibroblasts and vascular endothelial cells. We also found that established subcutaneous tumors could be visualized after intraturnoral injection of OBP-301 and Ad-GFP. A549 human lung tumors and SW620 human colon tumors transplanted into BALB/c nu/nu mice were intraturnorally injected with 8 X 10(5) plaque-forming units of Ad-GFP in combination with 8 X 106 plaque-forming units of OBP-301. Within 3 days of treatment, the fluorescence of the expressed GFP became visible by a three-chip color cooled charged-coupled device camera in these tumors, whereas intraturnoral injection of Ad-GFP alone could not induce GFP fluorescence. Moreover, intrathoracic administration of Ad-GFP and OBP-301 could visualize disseminated A549 tumor nodules in mice after intrathoracic implantation. Our results indicate that intratumoral or intrathoracic injection of Ad-GFP in combination with OBP-301 might be a useful diagnostic method that provides a foundation for future clinical application.

kn-title=Automatic Micromanipulation System using Stereoscopic Microscope
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=<p>In this paper, we developed a visual feedback system that controls a micromanipulator so that a needle head may reach a target. The system consists of a stereoscopic microscope, a micromanipulator, two CCD cameras and a personal computer. The position of the target and the needle head under stereoscopic microscope are measured three dimensionally by using two CCD cameras which are set to eyepieces of the microscope. It is necessary that the image processing employed be fast so that the micromanipulation can be carried out at a realistic rate. The image processing time for detecting the target and the needle head is greatly reduced by using image compression </p>

kn-abstract=This paper presents how the control performance of the feature-based visual servo system is improved by utilizing redundant features. Effectiveness of the redundant features is evaluated by the smallest singular value of the image Jacobian which is closely related to the accuracy in the world coordinate system. An LQ control scheme is used to resolve the controllability problem. Usefulness of the redundant features is verified by the real time experiments on a PUMA 560 manipulator.

en-abstract=
kn-abstract=<p>In this paper, we describe a visual feedback system using a stereoscopic microscope that controls a micromanipulator so that a needle may pierce a target as much length as desired. At first, for achieving the manipulation at a realistic rate, we proposed a strategy of moving the needle head. Secondarily, we developed an algorithm for prediction of the tip position of the needle head within the target. Before the needle pierces the target, the shape of the needle head is preserved as a reference pattern. After the needle piercing the target, the shape of the needle head within the target is predicted using the reference pattern and the tip position of the needle head can be detected. Experimental results indicate that the proposed system may be useful in micromanipulation such as microinjection to seeds </p>

kn-title=Improvement of odometry for omnidirectional vehicle using optical flow information
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=<p>Our research goal is to realize a robust navigation in indoor and outdoor environment for autonomous vehicle. An omnidirectional vehicle driven by four Mecanum wheels was chosen for our research platform. Mecanum wheel has 16 tilted rollers (45 degrees against the direction of wheel rotation) around the wheel, so the vehicle moves omnidirectionally by controlling these wheels independently. However, it has a disadvantage in odometry because of wheel slippage. Particularly, when the robot moves laterally, same wheels' rotations generate different traveling distance depending on friction of ground surface. To cope with the problem, we estimate robot's position by detecting optical flow of ground image using vision sensor (visual dead-reckoning). The estimation method is inaccurate comparing with odometry, but it is independent from friction of ground surface. Therefore, the estimated vehicle position can be improved by fusing odometry and visual dead-reckoning based on maximum likelihood technique. This paper describes an odometry method and a visual dead-reckoning method for omnidirectional vehicle, and fusion technique to improve the estimated position of the vehicle. Finally, experimental results support above technique </p>

en-abstract=
kn-abstract=<p>A stereoscopic microscope is widely used in a micromanipulation such as to operate genes and to inspect integration circuits. As in these tasks the micromanipulation is handled and makes too heavy burden to operators, it is desirable to perform the micromanipulation automatically. In this paper, we propose a visual feedback system for micromanipulation with stereoscopic microscope. This system takes less time to control the manipulator by reducing searching area to detect an object </p>

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The scanning electron microscopic studies of the clay minerals have usually been made on air-dried samples. The air-drying method is, however, not always preferable for H(2)O rich clay minerals such as imogolite because of their strong contraction in the dehydration process. The present writers examined the critical point drying for H(2)O rich clay mineral (imogolite) and proved that this drying method is excellent in preservation of natural surface of the minerals than that of air-drying. Imogolite which examined was separated from Kurayoshi pumice beds. The samples were treated first with OsO(4) solution and then were dehydrated progressively with ethanol. After completing above treatments, the imogolites which sealed in vessel were dried successively at critical point of CO(2). The samples were mounted onto brass stubs and coated first with carbon and then with Au-Pd alloy. The Japan Electron Optics Laboratory Co. scanning electron microscope Model JSM-50A which was installed in the Division of Rehabilitation Medicine in the present Institute was used at the operating conditions: accelerating voltage 25kV, magnifications ranging from 3000 to 40000. The scanning electron micrographs of the air-dried imogolite are shown in plate I, and cry tical point dried ones are in plate II and III. The former shows twig-like shape which indicated the effect of contractility, whereas the latter exhibits softly curled and entangled threads. The diameter of these threads ranges from 280A to 560A.

kn-abstract=A novel recycling process of blast furnace slag was developed in order to obtain colorless silica－rich solids by using phase separation of borosilicate glass. B(2)O(3) was added to blast furnace slag to promote the phase separation. The slag glasses were heat-treated above glass transition temperatures. The slag glass prepared from blast furnace slag gelled after the heat treatment and the subsequent three types of acid treatment. The ratios of SiO(2) component in the gels were 40 - 60mass%. On the other hand, phase separation was observed on the surface of the slag glasses prepared from pre-treated slag by 2.5N HCI after the heat treatment. After soaking in acid, they did not gel and changed to insoluble colorless solids. According to compositional analyses, it was found that the insoluble colorless solids contained 70 - 90mass% SiO(2). No colored ions such as Cr, Mn, and Fe were confirmed in the remaining insolubles by optical absorption measurement. Therefore, the colorless silica-rich solids were successfully obtained in the present process. The end products obtained in the present process are expected as material of glass.

kn-abstract=In this paper, we investigate a light-confinement phenomenon in the structure which has triangular latice composed of Double NeGative Metamaterial (DNGM). In
geometrical optics consideration, this structure is expected to confine lights completely by sequential refractions in the structure. We demonstrate it by using the two dimensional finite-difference time-domain simulations. We introduce Drude-Lorentz model for dielectric and magnetic dispersion of the material at optical frequencies. We analyze quantitatively the effects of energy loss in the DNGM on the light-confinement
efficiency.

en-title=Determination of anionic surfactants in an aqueous medium by differential photometric titration method
kn-title=微分光度滴定法による水溶液での陰イオン界面活性剤の定量
en-subtitle=
kn-subtitle=
en-abstract=A simple and rapid automatic photometric titration method was developed for the determination of anionic surfactants in a one-phase aqueous system with tetrabromophenolphthalein ethyl ester (TBPE) as an indicator. In the presence of non-ionic surfactants such as Triton X-100, protonated TBPE reacts with cation (Q(+)) to form an ion associate (Q(+)·TBPE(-)), causing a color change from yellow to blue. The titrant, distearyldimethylammonium ion, was added to an anionic surfactant solution at pH 3.2, and the absorbance changes were monitored by a fiber-optic sensor with a 630 nm interference filter. The end points were read from the inflection points with differential curves. Anionic surfactants at concentrations from 10(-6)10(-3) mol dm(-3) could be determined by the proposed method. The relative standard deviations of various anionic surfactants were 0.30.4%. The proposed method was applied to some practical samples, and the results, except for those of anionic surfactants possessing polyoxyethylenyl groups, were in good agreement with the results of the JIS titration method (Epton method) and a solvent extraction method with Ethyl Violet.
kn-abstract=微分光度滴定装置を用いて,水溶液での陰イオン界面活性剤を定量する方法について検討した.滴定終点決定の指示薬系としては,酸性染料のテトラブロモフェノールフタレインエチルエステル(TBPE)と非イオン界面活性剤のTriton X-100(TX-100)の混合溶液を用いた.TBPEは非イオン界面活性剤の存在下で,酸性では黄色となり可溶化しているが,滴定剤の第四級アンモニウムイオンと反応するとイオン会合体を形成し,解離型(TBPE-)の青色(λ(max)=610nm)となる.滴定剤には第四級アンモニウム塩のジステアリルジメチルアンモニウム・クロリド(DSDMA(+)・Cl(-))を用いた.本滴定法で10(-6)～10(-3)Mの濃度範囲の陰イオン界面活性剤が定量できる.実際試料の定量結果はオキシエチレン基を持つもの以外の試料において,JIS滴定法(JIS K 3362)及びエチルバイオレット抽出吸光光度法(JIS K 0101)とよく一致した.

en-abstract=健康正常人の血液などの組織中にはリン脂質過酸化物が極微量で存在し，疾病や老化によってその濃度が顕著に上昇する事が知られている．その事が明らかにされた当初は，極めて複雑な混合物をなす生体脂質中に含まれる不安定な極微量の過酸化脂質を単離・構造決定する事は殆ど不可能と考えられていた．現在もなお，そのような脂質過酸化物を生体組織から純粋に取り出し，構造決定したという報告は無い．従ってそのような分子種の化学的・生理学的性質は不明であったが，脂肪酸過酸化物が毒性を示す事から，リン脂質過酸化物もおそらく毒性を示すだろうと考えられてきた．このような漠然とした推定を科学的に明らかにするためには，化学合成によらざるを得ない．我々はこの未知の合成に取りかかった．しかし，従来の化学的手法のみでは不可能である事も明らかであった．その中で予想された困難の一つは極めて不安定なヒドロペルオキシ基を不飽和脂肪酸のある特定の位置にどのように導入するかという問題と，ヒドロペルオキシ基に影響を与える事なく合成中間体をどのように化学変換するかであった．第一の問題に対する解決策として，不飽和脂肪酸に大豆リポキシゲナーゼを作用させる事で解決する事ができた．植物に広く分布する酵素であるリポキシゲナーゼは植物中でリノール酸に作用して過酸化し，その生成物にヒドロペルオキシドリアーゼという酵素が作用して種々のアルデヒドが精製し，これは植物の青臭みを与える．第二の問題に対しては，リノール酸に導入された不安定なヒドロペルオキシ基をパーアセタールとしての保護する事により解決した．この保護基は，中間体から最終生成物に至るまでの反応条件，例えばDCCによるアシル化反応に対して安定である事が明らかとなった．この二つの問題を解決する事によって，リン脂質過酸化物の一つであるホスファチジルコリン過酸化物を世界に先駆けて成功した．さらにこのホスファチジルコリン過酸化物に微生物由来のホスフォリパーゼDを作用させる事によってホスファチジルエタノールアミン過酸化物，ホスファチジルセリン過酸化物やホスファチジルグリセロール過酸化物の合成にも成功した．また，トリグリセリド過酸化物の合成も可能になった．これらの脂質過酸化物が化学的に実態のあるものとして認識されてから，その生理作用に関する研究が広範に行われている．しかし，生体組織に存在するリン脂質過酸化物の生理学的役割は依然として明らかになっていない．ある種のリン脂質過酸化物が動物の免疫系を活性化するという報告もあり，必ずしも生体に対して悪い作用をするばかりではないようである．
kn-abstract=Chemoenzymatic synthesis of 1-stearoyl-2-hydropeoxyacyl-sn-glycerophospholipids including phosphatidylcholine (PC-OOH), phosphatidic acid (PA-OOH), phosphatidylethanolamine (PE-OOH), phosphatidylglycerol (PG-OOH) and phosphatidylserine (PS-OOH). The hydroperoxy acyl moieties were prepared via hydroperoxidation of linoleic, dihomo-γ-linolenic and arachidonic acids by soybean, potate lipoxygenase or autoxidation. Their hydroperoxy group was protected as a dimethylperacetal before condensation with lysophosphatidylcholine. Optically active lysophosphatidylcholine was prepared via short pathway involving lipase-catalyzed direct enantioselective stearoylation of 2-O-benzylglycerol and choline phosphate synthesis. Peroxy fatty acids and lysophosphatidylcholine thus obtained were condensed using dicyclohexylcarbodiimide
in chloroform. Removing the peracetal group in the product and purification by reverse-phase chromatography afforded the desired PC-OOH’s. PA-OOH, PG-OOH, PE-OOH and PS-OOH were obtained by phospholipase-D catalyzed transphosphatidylation from PC-OOH. As a reference compound for biological studies of hydroperoxy phopholipid, PC-OH's were also prepared in which hydroxy unsaturated fatty acyl group was linked to the sn-2 position of the glycerophospholipids.

kn-abstract=In this paper, we propose the method to determine the position of the 2 cameras for the multiviewpoints as the robot is the work place. The optical axit's direction of the 1st camera is determined in the base ot work contents in teleoperation. The multiviewpoints system uses the 2 camera units that aren't installed side by side, so that the direction of the 2nd camera is decided in the base of the angle between the optical axes' direction of 2 cameras. Next, the distance from the camera to the work place is determined according to the distance resolution of image on the monitor, and the camera type of which the point-blank range is not this distance is selected. And the efficacy ot this system is examined with an experiment.

kn-abstract=In the present paper an autopsy case report of Neuro-Behçet's syndrome has been made and patho-histological studies of the brain of the 8 autopsy cases reported previously as well as those of the present case have been conducted. The present case was a 47-years old man. In the ninth years after the onset of symptoms in the oral cavity and in the genitalia he was troubled repeatedly with diplopia. Gradually there appeared such symptoms as the disturbance of his gait, forced laughing, disturbance of speech, ataxia, and the inflammation at the sites of injection. He had remission and aggravation of these symptoms. However, he died of respiratory paralysis 17 years after the onset of oral aphtha and 8 years after the onset of diplopia. In the patho-histological observation of this case there were seen perivascular cell infiltration covering the entire cerebral parenchyma as well as a portion of meninges, revealing a picture of chronic disseminated panmeningoencephalitis and cerebral abscess of medulla oblongata. In addition, there were fibrinoid degeneration of the blood vessel wall and such degenerative changes in the blood vessels as fibrosis and proliferation of collagen fibers; and also circumscribed foci of glia cell proliferation, softening cavities and abnomal proliferation of consumptive pigments. These pathlogical changes were recognized in the entire brain, but they were especially prominent in brain-stem. There were no pathologica changes in the optic nerves and in the spinal cord. In the investigations of the patho-histological picture of the brain in our case as well as in the cases reported in literature, the common findings in Neuro-Behçet's syndrome are extensive disseminated perivascular cell infiltration of the brain, softning accompanied by a moderate proliferation of microglia cells and degenerative changes of the blood vessel wall. while these pathological changes are especially marked in the brain-stem, to a greater degree in the white matter than in the grey matter. Neuro-Behçet's syndrome has been found to resemble periarteritis nodosa and clinically it shows many common pathologic changes as found in collagene disease. Hence, it is assumed that Behçet's syndrome belongs to the collagene disease.

kn-abstract=After administering Zn(65)O and Zn(65)Cl(2) to guinea pigs the author investigated the difference in the distribution of these isotopes and also the distribution of Zn(65)Cl(2) in serum fractions and obtained the following results. 1. (a) The in vivo distribution of Zn(65)O was high in the lung, liver, heart, kidney, pancrease and intestine 15 minutes after its administration, in the lung, liver, spleen, pancreas, kidney and int stine two hours later, and two weeks later in the lung, large intestine, heart, liver, spleen, intestine and pancreas, the activity being in the order of the organs mentioned. In addition, the radio-activity detected in the urine is minute as compared with the quantity of Zn(65)O injected. (b) The in vivo distribution of Zn(65)Cl(2) after five hours its administration was found to be in the order of the liver, intestine, pancreas, large intestine, kidney and lung, showing a distinct difference from the the case of Zn(65)O administration. 2. The radio-activity of zinc ions combined with serum protein fractions after the Zn(65)Cl(2) administration was found in β-globulin, γ-globulin, albumin and α-globulin, the activity being descending order mentioned, and the relative specific activity (activity/area under optical density curve) was in the order of γ-globulin (12.5), β-globulin (6.9), albumin (2.3), and α-globulin (1.1).

kn-abstract=The total 23 cases were diagnosed as encephalomyelitis with abdominal disturbances in the Ibara districts from January, 1966 till August, 1967. Observations were made on incidences and characteristic clinical symptoms of the disease. 1. The number of the patients of adult females was greatest and more than twice as that of males. Onset of the disease was mostly found in the warm season. At present, particular age difference was not discernible in the incidences. 2. The patients with the disease were at first observed around 1965 and the number of those has a tendency to increase. 3. Characteristics of clinical manifestations were as follows: (a) Abdominal pain and constipation were frequent as prodromal signs, whereas diarrhea was not frequent. The tender point at the abdominal wall was located approximately at D(10). (b) As encephalomyelic nervous disorders at the lower limbs, a majority of the cases exhibited disturbance of foct flexicn, tenderness and contraction of thigh adductor muscles. Ataxia, together with subjective and objective sensory disturbances as well as increased patellar reflex, was observed in all cases. By contrast, disorders at the upper limbs were not common. As optic nerve disturvances, about 40% of the cases showed weakness of vision, narrowness of visual field, etc.

en-abstract=
kn-abstract=Metamaterial which has negative permittivity and permeability is investigated via computer simulations. Effects of the nanostructure on dielectric and magnetic properties of the material are taken into account by introducing the Drude-Lorentz model in the materials dispersion. We include multi-band process in the dielectric response in order to reproduce accurately experimental values of bulk Au thin film. Size effect on the dispersion is examined by comparing the model with that of a noble metal particle. Based on the dispersion model constructed, we analyze the electromagnetic response of nanostructured metamaterials to evanescent waves at microwave and optical frequencies via finite-difference time-domain simulatioins on parallel computer. A re- focusing and an amplification of the evanescent waves propagating through a metamaterial, consisting of metal
slab/vacuum stacking, is demonstrated for the frequencies of 30GHz and 744THz.

kn-abstract=1) 1-(14)C labelled (3R)-(-)-4-amino-3-hydroxybutanoic acid (l-GABOB) and (3S)-(+)-4-amino-3-hydroxybutanoic acid (d-GABOB) were prepared from their racemic compound using
camphor-10-sulfonic acid. These optical isomers were administered at the dose of 5.6μCi(1mg)
to mice intraperitoneally and observed that l-GABOB was uptaken more rapidly into blood and organs, and metabolized more rapidly in the liver and kidney than d-GABOB, and that l-GABOB could penetrate significantly into the brain, while d-GABOB could hardly do it. 2) These substances in the concentration of 10(-3)M were topically applied on the epileptogenic focus of the cat cerebral cortex induced by potassium benzyl penicillin. As the results of the experiment, no more spike was observed several minutes after l-GABOB administration (n=6, all cases). On the contrary, the optical isomer, d-GABOB, showed a very weakly effect (Spike counts were reduced to 64.5±3.8%, n=6, P<0.05), and racemic GABOB moderately (Spike counts were reduced to 16.4±5.5%, n=6, P<0.05). 3) These substances were applied on the giant neurone, identified subesophageal ganglia of the african giant snail (Achatina fulica Ferussac) by bath-application method and microdropapplication method. As the results of the experiment, it was clarified that l-GABOB inhibited more strongly the electrical activity of the neurone than d-GABOB did it.

kn-abstract=To clarify salt-resistant mechanism of Staphylococcus aureus from the standpoint of the passive transport, attempts were made to establish the experimental system of artificial model membrane, liposome, and to measure permeability of Na(+) to it. The liposomes were prepared from phospholipids of S. aureus cultivated in normal and 10% NaCl media and NaCl-sensitive mutants. 1. In physiological conditions, it is possible to form the stable liposome comprised of phospholipids or total lipids of S. aureus. The preparation methods give a remarkable difference in the shape of vesicles. In the case of particles produced by hand or mechanical shaking, the diversities in the size and shape of individual particles can be observed. Sonicator-prepared liposomes are small and homogeneous of particle size, and consist of unilamella rather than multilamella. 2. Salt concentration affects liposome formation. Cardiolipin containing abundant branchedfatty acid form stable vesicles even in a high concentration of NaCl solution. 3. The liposome prepared from phospholipids of 10% NaCl S. aureus suppresses more markedly in the rate of Na(+) diffusion than that of normal S. aureus. The experiments on the liposomes prepared from fractionated individual phospholipids indicate that cardiolipin containing branchedfatty acid contributes to salt-resistance of S. aureus as a barrier. 4. From optical measurements, it has been elucidated that the liposome of phospholipids prepared from S. aureus acts as an ideal osmometer, and non-electrolyte, glycerol, shows a similar behavior to Na(+) in permeability.

en-abstract=A follow-up study on 60 previously healthy patients with nomosymptomatic optic neuritis, retrobulbar neuritis and idiopathic optic atrophy is reported. 73 per cent of the cases with insidious onset and slow progression were male, and 70 per cent of the cases who was troubled repeatedly on vision were female. In many cases, fever, common cold and overwork had precipitated the optic neuritis. During the following period, 6 patients (15.4 % of cases with acute onset) suffered from the other neurological manifestations, and a half of them (7.7 % ) were diagnosed as multiple sclerosis. Patients, who was diagnosed as retrobulbar neuritis by ophthalmoscopic examination and, who was disturbed on vision bilaterally but unsimultaneously, and repeatedly have an affinity to multiple sclerosis. At the beginning of the disease, a mononuclear pleocytosis was noted in 20.5 per cent of the patients, and elevated total protein level in 35.9 per cent. Polyacrylamide gel disc electrophoresis of the lumbar CSF proteins from 39 patients and the measurement of IgG by single radial immunodiffusion from 10 patients, were carried out. It was characteristic that the electropherogram showed the increase of pre-albumin, fast α(2)-globulin + transferrin and γ-globulin, and the decrease of albumin. These results are similar to those in multiple sclerosis. IgG and IgG % is increased in cases of retrobulbar neuritis, although total protein content is high level in optic neuritis, and then, cases who was disturbed on vision unilaterally or bilaterally but unsimultaneously showed the high level of γ-globulin. Two of 3 patients who subsequently developed to multiple sclerosis, had the CSF findings indistinguishable from those in multiple sclerosis. In one patient, CSF protein level was normal but γ-globulin was increased selectively. Another patient showed the CSF findings with slightly elevated protein level, pleocytosis and increase of IgG and IgG % .

kn-abstract=Regional CO(2) reactivity of different areas were observed during acute intracranial hypertension produced by extradural balloon compression in dogs. Regional CBF was measured by as heat clearance method with two thermocouple probes, 1) in the parietal area adjacent to the balloon and the contralateral parietal area, 2) in the adjacent parietal area and the ipsilateral occipital area remote from the balloon, 3) in the adjacent two areas, parietal and temporal, of the damaged hemisphere. ICP was measured by an epidural microballoon method and a fiber optic pressure switch (Ladd co.). The findings were as follows. 1. Regional CO(2) reactivity was impaired first in the area adjacent to the balloon, later in the remote area, and lastly in the contralateral area. 2. The impairment of regional CO(2) reactivity of the parietal area adjacent to the balloon and the contralateral parietal area could be classified into the following 5 stages. Stage 1: (ICP less than 20 mmHg) ICP and rCBF of both sides were increased by CO(2) inhalation. Stage 2: (ICP ca. 30 mmHg) ICP was increased more. In the contralateral area, rCBF was increased, but in the adjacent area, the increment of rCBF by CO(2) inhalation was diminished. Stage 3: (ICP ca. 45 mmHg) ICP was increased. In the contralateral area, rCBF was increased, but in the adjacent area, rCBF was decreased by CO(2) inhalation (paradoxical response i.e. intracerebral steal syndrome or intracerebral squeeze phenomenon). Stage 4: (ICP ca. 75 mmHg) ICP was increased, but rCBF on both sides was not increased by CO(2) inhalation. Stage 5: (ICP more than 100 mmHg) ICP and rCBF on both sides were not increased by CO(2) inhalation. 3. This dissociation of regional CO(2) reactivity in various areas would be caused by intracranial pressure gradients, and the consequent difference in local tissue metabolites.

en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The cerebral blood volume (CBV) is an important parameter of cerebral hemodynamics. However, measurement of CBV has been difficult. We have devised a photoelectric method for measurement of regional CBV. The sensor of the apparatus was made of three components; a microlamp, a photodiode to which an infra-red filter was attached, and a polyethylene balloon, or polyethylene catheter with its tip open for intracranial pressure (ICP) measurement. These were pasted with silicon rubber. The sensor was applied to the brain surface to measure the intensity of the optical absorption (OA) of hemoglobin in the brain tissue. OA remained nearly constant despite various alterations in cerebral blood flow (CBF), brain tissue pressure, and water content of the brain. Both OA and ICP increased during vasodilatation induced by CO(2) inhalation, compression of the jugular veins, or intravenous injection of Papaverine hydrochloride. Both decreased during vasoconstriction induced by hyperventilation or severe arterial hypotension. These results suggest that OA reflects changes of CBV. The disadvantages of this method are that the absolute CBV and the CBV in the deeper brain tissues can not be measured and that the operative field has to be kept dark. However, this method has several advantages; (1) Regional CBV is continuously measured without radionuclide or other specific indicators. (2) This method does not require a skilled technique. (3) The cerebral transit time can be measured by injection of saline or other indicators into the right brachial artery. (4) This device can also measure ICP.
