It has been reported that host defense responses, such as phagocytic function of neutrophils and natural killer (NK) cell activity of lymphocytes, are impaired in cirrhotic patients. This review will concentrate on the impairment of innate immune responses in decompensated cirrhotic patients and the effect of the treatment by branched-chain amino acids (BCAA) on innate immune responses. We already reported that phagocytic function of neutrophils was significantly improved by 3-mo BCAA supplementation. In addition, the changes of NK activity were also significant at 3 mo of supplementation compared with before supplementation. Also, Fisher’s ratios were reported to be significantly increased at 3 mo of BCAA supplementation compared with those before oral supplementation. Therefore, administration of BCAA could reduce the risk of bacterial and viral infection in patients with decompensated cirrhosis by restoring impaired innate immune responses of the host. In addition, it was also revealed that BCAA oral supplementation could reduce the risk of development of hepatocellular carcinoma in cirrhotic patients. The mechanisms of the effects will also be discussed in this review article.

Gastroesophageal reflux disease (GERD) contributes substantially to morbidity and to costs in the United States health care system. The burden of this disease has resulted in attempts at improving diagnosis and characterizing patients. Numerous research and technical advances have enhanced our understanding of both the utility and limitations of a variety of diagnostic modalities. The purpose of this review is to highlight recent advances in GERD diagnostic testing and to discuss their implications for use in clinical practice. Topics addressed include esophageal pH monitoring, impedance testing, symptom association analyses, narrow-band imaging, and histopathology.

In modern society, the population, wealth and social functions are increasingly concentrated in a few large cities. Such concentration brings about efficiency while at the same time it increases the vulnerability of the society. To address this issue, the Science Council of Japan（SCJ） published a proposal entitled ＂Shape Cities and Societies Safer against Severe Earthquakes＂. It makes a variety of suggestions for enhancing the seismic resilience of large cities, including：（1） comprehensive thinking based on the latest scientific knowledge and rich imagination;（2） selection of sites suitable for residence and social activities;（3） introducing the urban seismic coefficient;（4） promoting the enhancement of the seismic performance of buildings and civil structures;（5） easing the concentration of population and functions;（6） building communities that enable shelter and escape;（7） resilient technology of information and communication system and its effective utilization;（8） preparation and implementation of emergency response after earthquakes;（9） development and application of new structural seismic technology;（10） learning from domestic and foreign earthquake disasters and launching of international cooperation and knowledge sharing and（11） taking actions from a multidisciplinary perspective. The proposal is introduced in this paper.

An unsymmetrical diboron,(pin)B–B(aam),is smoothly added across a carbon–carbon triple bond of various terminal alkynes under platinum catalysis,resulting in the regio-and stereoselective formation of cis-vic-diborylalkenes via B(aam)-installation at the terminal *** use of a highly electron-deficient triarylphosphine ligand,P(BFPy)_(3),is indispensable for the regiocontrol,and electron-deficiency in ligands has been proven to be closely correlated with the regioselectivity.
