Abstract | The efficacy and safety of endoscopic submucosal dissection (ESD) for superficial cancer of the pharynx are still unclear. To identify clinicopathological features of superficial pharyngeal cancer, and the efficacy and safety of ESD, we retrospectively assessed 70 pharyngeal cancers in 59 patients who underwent ESD. Of these patients, 61.0% and 50.8% had a history of esophageal cancer and head and neck cancer, respectively. The median tumor size was 15 mm, and 75.7% of the lesions were located at the piriform sinus. The en bloc resection rate was 94.9%. Treatment-related adverse events occurred in 8 cases, but there was no treatment-related death. The lateral margin was positive for neoplasm in 3 lesions (4.3%) and inconclusive in 27 lesions (38.6%), but no local recurrence was observed. Cervical lymph node metastasis was observed in 6 patients, and was successfully treated by cervical lymph node dissection. The three-year overall survival rate was 91.5% (95%CI: 76.6-97.3%) and the cause-specific survival rate was 97.6% (95%CI: 84.9-99.7%). In conclusion, ESD for superficial pharyngeal cancer was safe and effective. “Resect and watch” is probably a feasible and rational strategy for treatment of patients with superficial pharyngeal cancer. |

Abstract | Cell clusters, or groups of cells sharing a single chondron-like structure, are frequently found in degenerated areas of the osteoarthritic (OA) meniscus. However, little is known about these meniscal clusters in humans. The aim of our study was to determine the composition of the extracellular matrix deposition around cell clusters in human OA menisci. Twenty-six menisci were obtained through total knee arthroplasty from patients with OA knee joints. The specimens were subjected to safranin O staining and immunostaining for Sry-type HMG box 9 (SOX9), type II collagen, and aggrecan. Their signal density after staining was assessed using ImageJ software. Five regions of interest were analyzed within each tissue sample. The SOX9, type II collagen, and aggrecan densities were considerably higher in cluster areas than in intact superficial layers of the meniscus. In addition, a substantial difference was detected between cluster areas and degenerative areas without cell clusters. We demonstrated that cell clusters localized near fissures and clefts showed remarkable uniformity in menisci exposed to a broad range of injuries. In addition, the chondrogenic proteins SOX9, type II collagen, and aggrecan were highly expressed in these tissues. |

Abstract | Medial meniscus (MM) posterior root tear (PRT) results in joint overloading and degenerative changes in the knee. MM root repair is recommended to prevent subsequent cartilage degeneration following MMPRT. Favorable clinical outcomes have been reported after transtibial pullout repair of MMPRT. However, it is unclear whether pullout repair can cause compositional change in the MM posterior segment. We examined this question in 14 patients who underwent MMPRT pullout repair. Magnetic resonance imaging examinations were performed preoperatively and 3 months postoperatively at 10° knee flexion. The region-of-interest was marked along the MM posterior segment edge. Intra-meniscal signal intensity (IMSI) was expressed as the signal intensity ratio of the repaired MM to the intact lateral meniscus, which was used as a control. MMPRT pullout repair reduced IMSI from 1 to 0.915±0.096 (range, 0.760-1.074) 3 months postoperatively (p=0.006, power=0.90). Meniscal degeneration causes high proton density-weighted imaging signal intensity of the meniscal body. In our study, MMPRT pullout repair reduced IMSI contrary to other tears. This technique may decrease the MM posterior segment signal intensity by restoring the hoop tension mechanism. Measuring IMSI may be useful to assess the effect of MMPRT pullout repair on meniscal healing. |

Abstract | Daclatasvir (DCV) + asunaprevir (ASV) combination therapy has become available for patients with hepatitis C virus (HCV) serogroup 1 infection. We studied the efficacy of this therapy by focusing on the factors associated with sustained virological responses (SVR) including resistance-associated variants (RAVs) and mixed infection of different HCV genotypes. We enrolled 951 HCV serogroup 1-positive patients who received this combination therapy at our hospital or affiliated hospitals. The presence of RAVs in non-structural (NS) regions 3 and 5A was analyzed by direct sequencing. HCV genotypes were determined by PCR with genotype-specific primers targeting HCV core and NS5B regions. SVR was achieved in 91.1% of patients. Female sex, age > 70 years, and RAVs were significantly associated with non-SVR (p<0.01 for all). Propensity score-matching results among the patients without RAVs regarding sex, age, and fibrosis revealed that mixed HCV infection determined by HCV NS5B genotyping showed significantly lower SVR rates than 1B-mono infection (p=0.02). Female sex and RAVs were significant factors associated with treatment failure of this combination therapy for patients with HCV serogroup 1 infection. Mixed HCV infection other than 1B-mono infection would be useful for predicting treatment failure. |

Abstract | Acoel flatworms can move in a variety of ways such as muscular and ciliary movements via cytoskeletal elements and their neural regulations. However, those locomotive mechanisms have not yet been fully elucidated. In this study, we examined the distribution of cytoskeletal elements including filamentous actin (F-actin) and tubulin, and the neuroanatomical organization in an acoelomorph worm, Praesagittifera naikaiensis (P. naikaiensis). Video microscopy revealed the elongation/contraction and the bending/rotation processes, and the ciliary gliding movement of P. naikaiensis. Histochemical and morphological analysis demonstrated that F-actin networks of inner longitudinal and outer circular muscle fibers were positioned along the entire surface of the body, and that the average distance between the circular muscle fibers in the contracted organism was decreased in the anterior region compared with that in the elongated organism. Electron microscopy showed dense bodies on the muscle cells of P. naikaiensis, which indicates that those muscle cells have the appearance of vertebrate smooth muscle cells. Immunohistochemical analysis revealed that -tubulin-positive signals on the ciliary microtubules had close contact with the F-actin network, and that neurite bundles labelled with anti dSap47 antibody as a neuronal marker run along the anterior-posterior body axis. These results indicate that the well-organized cytoskeletal elements and their neural control systems are preserved in P. naikaiensis, and that their mechanisms involved in those regulation systems are similar to those vertebrate systems. Further studies are needed to clarify the physiological mechanisms underlying the muscular and ciliary movements in P. naikaiensis. |

Abstract | There are many limitations and difficulties in terms of expanding agricultural lands. Also, some other factors affect the agricultural lands that result in decreases such as climate change, erosion and misuse of the lands. It is clear that these developments in agricultural land use threaten the future of human welfare, social conditions, economic growth and food supply. In this study, we examined the land use and its significance that represent past agriculture and regional characteristics in the Chugoku region including Okayama prefecture and the Seto Inland Sea. Specifically, among the products called as industrial crops, such as cotton, pyrethrum, rush, tobacco, rapeseed, mulberry and tea, were adopted as the indicators. Currently, these landscapes can hardly be seen, only leaves of tobacco and tea can still be seen in mountainous areas. Even in agricultural land usewhich has almost disappeared now, it may have indirect influence as in the case of reclaimed land and rush products. Therefore, we reaffirmed in this study the reasons for their existence and their significance. |

Abstract | The gastrointestinal (GI) tract is the most frequently involved site of extranodal non-Hodgkin lymphomas, and diffuse large B-cell lymphoma (DLBCL) is the most common subtype occurring in the GI tract. TNFAIP3 (A20) genetic alterations were reported to be involved in DLBCL’s pathogenesis and a portion of GI-DLBCL cases harbor this alteration. However, the frequency and clinicopathological relations focusing on small and large intestinal DLBCL are unclear. Here, we examined A20 deletion and protein expression and analyzed the clinicopathological features of 52 cases of primary intestinal DLBCL. The most frequently involved site was the ileocecal region (75%), followed by small bowel (13.5%) and large intestine. Immunohistochemically, the ileocecal cases expressed BCL6 (p=0.027) and MUM1 (p=0.0001) significantly more frequently than the small intestinal cases. Six of 47 cases (13%) had A20 heterozygous deletion, whereas all 6 heterozygously deleted cases had detectable A20 protein expression. In summary, A20 abnormality was less prevalent among intestinal DLBCLs with some discordancy between gene deletion and protein expression. Although the A20 alteration status did not affect any clinicopathological characteristics in this series, further studies exploring alterations of A20 and other NF-κB components in primary intestinal DLBCL are needed. |

Abstract | Although the extratropical cyclone is one of the basic systems that characterize the weather and climate in mid-latitude regions with the large meridional temperature gradient, its activity and characteristics would be greatly influenced by the seasonal transition and regional differences of the mean atmospheric fields such as between Europe and East Asia. Furthermore, detailed knowledge of the daily cyclone activity would help to understand deeply the differences of regional climatology including seasonal cycles among various areas. In such interest, the present study performed a case study on the cyclone activity around Europe from winter to spring of 2000. In winter, intraseasonal variation of the Icelandic Low was dominant. In the stage when such intraseasonal-scale Icelandic Low approached to the northwestern Europe, the several lows passed eastward with a few days interval around the intraseasonal-scale low pressure area or its southern edge where the baroclinicity was relatively strong. It is also noted that their center pressure was rather low (below 980hPa). After April, when the seasonal mean Icelandic low had disappeared, different types of the intra-seasonal-scale cyclones and anticyclones were dominantly observed. In the lower SLP stage of the intraseasonal variation in Europe, the low to the southwest of England in the middle of April was of the equivalent barotropic structure and persisted for about ten days. On the other hand, high pressure area extending from England to the northern coast of Germany also persisted for about half month. The southern half of that high area was also of equivalent barotropic structure with warmer air there. |

Abstract | Analyzing of sedimentary facies and structure together with regional field mapping were studied in the mélange unit, upper Cretaceous Shimanto Belt, Wakayama Pref., SW Japan. The field survey was concentrated in the coast of Shiofuki-iwa, Miyama Complex, Hidakagawa Belt where soft deformations penetrate throughout the mélange unit. Brittle to ductile faults associated as later deformations are excluded. The mélange unit is subdivided into the Y-shear zone (YSZ) and P-foliation zone (PFZ). The YSZ is composed of thick lenticular sandstone (trends subparallel to the direction of the mélange), intense shear band (thin layer with concentrated prelithification shear deformation) and mudstone dominant mélange. The PFZ is composed of mudstone dominant mélange (associated with foliations which slightly oblique to the direction of the YSZ) and lenticular sandstone (slightly oblique to the direction of the YSZ). The intense shear band separates the YSZ and PFZ. Preserved radiolarian fossils free from deformation in the intense shear band is the evidence of the prelithification shear deformation in the mélange. A remarkable-fact is that the structures of mélange unit are formed under sinistral sense of shear. The mélange unit in the Shiofuki-iwa is ascribed to be formed by sinistral sense of shear during sediments were prelithified. |
