Ongoing Applicative Studies of Plant Thioredoxins

Molecular Plant 2014年第1期7卷 4-13页

作者： Hiroyuki yano National Food Research Institute National Agriculture and Food Research Organization Kannondai 2-1-12 Tsukuba Ibaraki 305-8642 Japan

Studies triggered by the discovery of the function of thioredoxin （Trx） in photosynthesis have revealed its role throughout biology. Parallel biochemical and proteomic analyses have led to the identification of its numerous puta- tive targets. Recently, to verify the biological significance of these targets, in vivo studies using transformants in which Trx is overexpressed or suppressed are in progress, and the transformants themselves that are being used in such studies show their potential applicative values. Moreover, Trx＇s mitigation of allergenicity for some proteins offers promising prospects in the food industry. Practical studies based on redox regulation, once only on the horizon, are now achieving new dimensions. This short review focuses on the industrial applications of Trx studies, the current situation, and future perspectives. The putative targets obtained by the proteomics approach in comparison with in vivo observations of the transformants are also examined. Applicative studies of glutathione, a counterpart of Trx, are also discussed briefly.

Short-and long-term outcome of interferon therapy for chronic hepatitis B infection

引用

World Journal of Gastroenterology 2014年第37期20卷 13284-13292页

作者： Yasushi Seo Yoshihiko yano Division of Gastroenterology Department of Internal MedicineKobe University Graduate School of Medicine Internal Medicine and Ophthalmology Clinic

Hepatitis B virus (HBV) infection is a serious clinical problem worldwide. Conventional interferon (IFN)-α has been approved for the treatment of chronic hepatitis B (CHB). Short-term studies have demonstrated that IFN-based therapy is moderately effective in inducing the loss of hepatitis e antigen (HBeAg) or seroconversion (30%-40%) in HBeAg-positive patients and also produces sustained HBV DNA suppression (20%-30%) in HBeAg-negative patients. Many studies have reported a correlation between the HBV genotype and response to IFN treatment. The highest response rate to IFN treatment was found in patients infected with HBV genotype A, followed by HBV genotypes B, C, and D. The long-term effect of IFN-α on CHB has not yet been elucidated. The ability of IFN-α treatment to prevent new cirrhosis, complications associated with cirrhosis, and development of hepatocellular carcinoma (HCC) is controversial. The beneficial effect of IFN-α treatment in reducing the development of HCC has mainly been observed in treatment responders who already have cirrhosis. These inconsistent findings may be attributed to the inevitable limitations of comparisons across studies, including differences in the baseline characteristics of the study and the moderate suppression of HBV replication by IFN-α relative to nucleoside/nucleos(t)ide analogs.

Variability in salt flux and water circulation in Ota River Estuary, Japan

引用

Water Science and Engineering 2013年第3期6卷 283-295页

作者： Mohammad SOLTANIASL Kiyosi KAWANISI Junki yano Kazuhiko ISHIKAWA Department of Civil and Environmental Engineering Graduate School of Engineering Hiroshima University

In this study the sub-tidal and intra-tidal variations of salt fluxes in the upstream section of a shallow estuary （with a water depth of less than 3 m） were investigated. The salt fluxes were estimated based on the cross-sectional average salinity and velocity measured by the fluvial acoustic tomography system （FATS）. The results indicate that the magnitude of seaward fluxes is approximately two times greater than that of landward fluxes under normal conditions. The results of short-term observation in the study area indicate that there is a phase lag of the bottom and surface salinities between the regions with the largest and smallest depths. The vertical shear flux with a peak value of-0.7 m2/s during the ebb tide indicated an important contribution to the total salt flux compared with the advective flux. A phase lag occurred between the vertical shear terms in the regions with the largest and smallest depths, which resulted from the correlation between the vertical variations of the salinity and velocity and the existence of transversal velocity circulations.
