The authors present evidence to suggest that variations in the snow depth over the Tibetan Plateau （TP） are connected with changes of North Atlantic Oscillation （nao） in winter （JFM）. During the positive phase of nao, the Asian subtropical westerly jet intensifies and the India-Myanmar trough deepens. Both of these processes enhance ascending motion over the TP. The intensified upward motion, together with strengthened southerlies upstream of the India-Myanmar trough, favors stronger snowfall over the TP, which is associated with East Asian tropospheric cooling in the subsequent late spring （April-May）. Hence, the decadal increase of winter snow depth over the TP after the late 1970s is proposed to be an indicator of the connection between the enhanced winter nao and late spring tropospheric cooling over East Asia.

AIM To define clinical criteria to differentiate eosinophilic gastrointestinal disorder(Eo GD) in the esophagus. METHODS Our criteria were defined based on the analyses of the clinical presentation of eosinophilic esophagitis(Eo E), subepithelial eosinophilic esophagitis(s Eo E) and eosinophilic esophageal myositis(Eo EM), identified by endoscopy, manometry and serum immunoglobulin E levels(s-Ig E), in combination with histological and polymerase chain reaction analyses on esophageal tissue *** In five patients with Eo E, endoscopy revealed longitudinal furrows and white plaques in all, and fixed rings in two. In one patient with s Eo E and four with Eo EM, endoscopy showed luminal compression only. Using manometry, failed peristalsis was observed in patients with Eo E and s Eo E with some variation, while Eo EM was associated with hypercontractile or hypertensive peristalsis, with elevated s-Ig E. Histology revealed the following eosinophils per high-power field values. Eo E = 41.4 ± 7.9 in the epithelium and 2.3 ± 1.5 in the subepithelium; s Eo E = 3 in the epithelium and 35 in the subepithelium(conventional biopsy); Eo EM = none in the epithelium, 10.7 ± 11.7 in the subepithelium(conventional biopsy or endoscopic mucosal resection) and 46.8 ± 16.5 in the muscularis propria(peroral esophageal muscle biopsy). Presence of dilated epithelial intercellular space and downward papillae elongation were specific to Eo E. Eotaxin-3, IL-5 and IL-13 were overexpressed in Eo *** Based on clinical and histological data, we identified criteria, which differentiated between Eo E, s Eo E and Eo EM, and reflected a different pathogenesis between these esophageal Eo GDs.

Background: In actual clinical settings, an occupational therapist (OT) encounters a patient with moderate Alzheimer’s disease (AD) walking with an anxious expression on the ward. The OT walks with the patient and encourages them to look at the symbol tree in the center of the ward. Additionally, when the patient talks to the OT, the OT empathizes with them and responds appropriately. As a result, many patients feel less anxious and become calmer. Therefore, in this study, the OT walked with an elderly female patient in her 80s with moderate AD and measured the patient’s autonomic nervous system responses. The study aimed to verify to what extent the results matched the OT’s clinical observational perspective. Methods: An OT with over 10 years of experience and a good relationship with the patient conducted one-on-one walking sessions with the patient. We divided the sessions into five-time periods: when the patient and OT were sitting on a sofa, and when they were walking. We implemented the same approach to the patient as usual. Therefore, we prompted the patient to look at the symbol tree during the walking session. Additionally, when the patient talked to the OT, the OT empathized and gave appropriate responses. We checked the changes in the patient’s autonomic nervous system responses in each time period. Results: This study showed that when walking with an OT, patient with moderate AD had a significant increase in parasympathetic nervous system (PNS) activity. Therefore, it is suggested that the involvement of professionals such as the environment and the OT during walking training for Alzheimer’s patients may lead to improved mental stability. Conclusion: This study suggests that walking together with an OT may have a positive effect on the PNS of female patient with AD. The study also suggests that there is a potential agreement between clinical observation by the OT and evaluation results based on autonomous nervous system reactions. However, due to the lim

Bacteriophage morphogenesis is a model system for investigating sequential molecular assembly. The Mu phage is one of the most classical Myoviridae. Although it is well known as a mobile genetic element, the details of its morphogenesis remain unclear. Analysis of conditional lethal mutants and genome analysis of the Mu phage have suggested that genes 42, 43, 44, 45, 46, 47, and 48 are essential for its baseplate assembly. Since we have already reported X-ray structures of the products of genes 44 (gp44) and 45 (gp45), we here tried to purify the remaining Mu phage baseplate subunits, gp42, gp43, gp46, gp47, and gp48, to investigate the baseplate assembly process. In the case of gp42 expression, the transformed E. coli cells showed growth inhibition after induction and no gp42 fractions were observed. However, gp43, gp46, gp47, and gp48 were successfully expressed and purified, although gp48 could not be applied to further analysis, because the amount of soluble fraction was very low. Based on analytical ultracentrifugation, we concluded that gp43 formed a monomer, gp46 was a monomer, and gp47 occurred as both a monomer and dimer in solution. Moreover, we found that gp43 and gp45 formed an intermediate complex in the baseplate assembly process.
