Title Alternative Sexual Dimorphism of Arginine Vasotocin Neuron in Birds
FullText URL srfa_112_019_022.pdf
Author Saito, Noboru|
Abstract Arginine vasotocin (AVT) is one of neurohypophysial peptides in birds and is well known both as an antidiuretic and oxytocic hormone. AVT is produced in the hypothalamus and mainly synthesized in magnocellular neurons, supraoptic nucleus (SON) and paraventricular nucleus (PVN). Recent, immunocytochemistry and in situ hybridization results indicate that AVT is also synthesized in parvocellular neurons corresponding to mammalian stria terminalis (nST). The AVT neurons in nST in the male are more numerous than those in the female. Therefore, these data suggest that there is sexual dimorphism in the distribution of AVT neurons. Several experiments involving electrical lesion, testosterone implantation, and the detection of the immediately-early gene expression in birds expressing copulatory behavior suggested that nST and nucleus praeopticus medialis (POM) were related to the reproductive behavior. When male embryo was treated with estradiol, the distribution of AVT neurons assumes the same distribution as found in the female, and reproductive behavior was abolished, suggesting that AVT in the brain has an important role in reproductive behavior.

Title Alternative Studies on l-Glutamate Oxidase with Strict Substrate Specificity from Streptomyces sp.
FullText URL srfa_112_013_018.pdf
Author Nakayama, Natsume| Inagaki, K.|
Abstract l-glutamate oxidase (LGOX) from Streptomyces sp. is a heterohexameric flavin enzyme that catalyzes the oxidative deamination of l-glutamate to form α-ketoglutarate with ammonia and hydrogen peroxide. LGOX shows strict substrate specificity for l-Glu. In addition, it is highly thermostable and pH stable. Because of these properties, LGOX is currently used as a biosensor for the trace determination of l-Glu in the food industry and clinical laboratories. The full-length cDNA is 2103 bp and is encoded by a single polypeptide chain consisting of 701 residues including subunits α-γ-β. The LGOX gene was heterologously expressed in Escherichia coli JM109. The LGOX precursor expressed in E. coli is a homodimer with weak enzymatic activity and becomes a heterohexamer upon activation by protease treatment. X-ray crystallography and docking studies of purified recombinant LGOX suggest that the Arg305 residue is a key residue for substrate recognition. Mutant analysis showed that Arg305 is essential for substrate recognition, as the activity toward l-Glu was greatly reduced and substrate specificity was changed in some enzymes. The functional analysis of R305E-LGOX, which is an l-Arg oxidase, revealed that R305E-LGOX can be used as a enzyme biosensor for l-Arg.

Abstract This study aimed to investigate whether seed cold priming by PEG‒6000, followed by re‒drying would affect the germination, growth, and flowering of Eustoma ‘Exe Lavender’ raised seedling under high temperatures. Seeds of control treatment were not treated with cold‒priming or re‒drying. In experiment 1, seeds were cold‒primed with water and PEG‒6000 at ‒0.75 and ‒1.5 MPa for 5 weeks at 10°C in the dark and then subjected to re‒dried and storage for 30 days at 10°C. The results showed that cold‒primed seeds germinated earlier than those of the control. Compared to water treatment, plants grown from PEG‒6000 treatments and re‒drying showed similar germination rate, bolting rate, days to bolting, bolting node and flowering rate. In experiment 2, cold priming periods by water and ‒1.5 MPa PEG‒6000 were investigated for 4, 5, 6, 7, and 8 weeks. ‘Exe Lavender’ seeds treated with cold water and in the dark for longer than 5 weeks increased their percentage of radicle emergence and decreased germination rate after 30 days of re‒drying and storage. Meanwhile, those treated with cold-PEG did not protrude the radicle even for 8 weeks of priming and maintained the germination rate after re‒drying and storage. Days to bolting and days to flowering tended to decrease when the priming period decreased. The results suggest that the seed cold priming treatment by ‒1.5 MPa PEG‒6000 and subsequent re‒drying improved germination rate and maintained bolting rate and flowering rate in Eustoma compared to cold priming treatment by water raised seedling under high temperature conditions.

Abstract Long day (LD) treatment is frequently applied for horticultural crops, including strawberry, and sufficient effect similar to 4 to 6hours of day time elongation in the evening can be achieved by 1 to 3hours of night break in the mid night. Incandescent lamps (IC) have long been an important light source, but the general incandescent lamps are out of production and have been replaced with LED or florescent lamps (FL). Thus, we compared light sources and their color temperature (2,800K, warm white similar to IC; 6,500K, daylight) in different lighting programs. The effectiveness of 3 and 4cycles of alternate intermittent lighting, 30min on/30min off, were equal to and larger than 2hours of night break, respectively. Measured intensity of illumination (lux) at the canopy surface by 2,800K LED (6.9W) and FL (12W) was 1.50 and 0.95times as large as IC (54W), but leaf growth under LED and FL was similar to and less vigorous than IC, respectively. On the other hand, intensity values of illumination by 6,500K LED (6.9W) and FL (12W) were both 1.20times as large as 2,800K ones, but 6,500K light sources were much less effective compared to 2,800K ones. Daylight type LED and FL which have higher luminance efficiency but emit less red light compared to warm white ones, are not suitable as alternative light sources for IC.

Abstract 逆カルチャーショックの存在は知られるが、その機序の解明は十分とは言い難い。滞在先によく馴染むほど再適応は困難になるとみる「弓引きモデル」が成り立つかどうかをRQ1、文化受容と帰国後のその変化をRQ2、逆カルチャーショックの心理的機序をRQ3として、日本人元留学生12名に半構造化面接を行った。渡航先は北米6名、欧州3名、オセアニア1名、アジア2名であった。語りから社会文化的な認知や行動の変容と維持を抽出し、KJ法を用いて分析した。帰国後切り替えられた文化行動には、表出性(双方向的授業、主張性、明言、相互性)、社会的圧力(自由さ、過度な気遣いなし、おおらかさ)、親近性(身体接触を伴う挨拶、フレンドリーさ、パーティー)のカテゴリが見いだされた。二文化性への態度として、習慣取り入れ、受容の態度、母文化拒否感、転換への消極性、スイッチングのカテゴリが認められた。弓引きモデルの該当例は8名見られた。滞在先で文化受容が進み、帰国後は二文化を客観視する2名は再適応の困難が小さく、俯瞰モデルと名付けられた。文化受容が限定的で母文化が比較的維持され、再適応の速やかな2名は維持モデルと名付けられた。滞在先での文化受容は逆カルチャーショックを潜在的に準備するが、母文化観が相対的でなく拒否的な場合に、再適応の難度が高まる。この機序は、文化受容の可逆性や準拠文化の択一性、文化的スイッチングの機能に関わる問いに繋がる。
