BACKGROUND Perinatal brain injury may lead to later neurodevelopmental disorders,whose outcomes may vary due to neuroplasticity in young children.Recent neuroimaging studies have shown that the left parietotemporal area(which includes the left inferior parietal lobe)is associated with phonological awareness and decoding skills,which are essential skills for reading acquisition in children.However,the literature on the effect of perinatal cerebral injury on the development of phonological awareness or decoding ability in childhood is limited.CASE SUMMARY We report the case of an 8-year-old boy who presented with reading difficulty following a perinatal injury in the parieto-temporal-occipital lobes.The patient was born at term and was treated for hypoglycemia and seizures during the neonatal period.Diffusion-weighted brain magnetic resonance imaging on postnatal day 4 revealed cortical and subcortical hyperintensities in the parieto-temporo-occipital lobe.At the age of 8 years,physical examination was unremarkable,aside from mild clumsiness.Despite occipital lobe injury,the patient had adequate visual acuity,normal eye movement,and no visual field defects.Full-scale intelligence quotient and verbal comprehension index on Wechsler Intelligence Scale for Children-Fourth Edition were 75 and 90,respectively.Further assessment revealed adequate recognition of Japanese Hiragana letters.However,he had significantly slower reading speed in the Hiragana reading test than control children.The phonological awareness test revealed significant errors(standard deviation+2.7)in the mora reversal task.CONCLUSION Patients with perinatal brain injuries in the parietotemporal area require attention and may benefit from additional reading instructions.

Laparoscopic cholecystectomy(LC) does not require advanced techniques, and its performance has therefore rapidly spread worldwide. However, the rate of biliary injuries has not decreased. The concept of the critical view of safety(CVS) was first documented two decades ago. Unexpected injuries are principally due to misidentification of human factors. The surgeon's assumption is a major cause of misidentification, and a high level of experience alone is not sufficient for successful LC. We herein describe tips and pitfalls of LC in detail and discuss various technical considerations.Finally, based on a review of important papers and our own experience, we summarize the following mandatory protocol for safe LC:(1) consideration that a high level of experience alone is not enough;(2) recognition of the plateau involving the common hepatic duct and hepatic hilum;(3) blunt dissection until CVS exposure;(4) Calot's triangle clearance in the overhead view;(5) Calot's triangle clearance in the view from underneath;(6) dissection of the posterior right side of Calot's triangle;(7) removal of the gallbladder body; and(8) positive CVS exposure. We believe that adherence to this protocol will ensure successful and beneficial LC worldwide, even in patients with inflammatory changes and rare anatomies.

Neural Regeneration Research 2022年第1期17卷 87-88页

作者： Takeshi nakamura Shingo Koinuma Division of Cell Signaling Research Institute for Biomedical SciencesTokyo University of ScienceNodaJapan

Mammalian central nervous system(CNS)neurons lose axon regenerative ability as they mature.This failure to regenerate shows a clear contrast to a remarkable potential of axon growth during embryonic development and after an injury in the peripheral nervous system(PNS)(Hilton and Bradke,2017).The absence of regeneration in the mature CNS neurons is caused by an inhibitory influence of the environment of the injured axons and the deficit of intrinsic factors that enable regeneration in the PNS(He and Jin,2016).

Mechanotransduction,a conversion of mechanical forces into biochemical signals,is essential for human development and physiology.It is observable at all levels ranging from the whole body,organs,tissues,organelles down to molecules.Dysregulation results in various diseases such as muscular dystrophies,hypertension-induced vascular and cardiac hypertrophy,altered bone repair and cell deaths.Since mechanotransduction occurs at nanoscale,nanosciences and applied nanotechnology are powerful for studying molecular mechanisms and pathways of mechanotransduction.Atomic force microscopy,magnetic and optical tweezers are commonly used for force measurement and manipulation at the single molecular level.Force is also used to control cells,topographically and mechanically by specific types of nano materials for tissue engineering.Mechanotransduction research will become increasingly important as a sub-discipline under nanomedicine.Here we review nanotechnology approaches using force measurements and manipulations at the molecular and cellular levels during mechanotransduction,which has been increasingly play important role in the advancement of nanomedicine.

With the significant advances in cancer genomics using next-generation sequencing technologies,genomic and molecular profilingbased precision medicine is used as a part of routine clinical test for guiding and selecting the most appropriate treatments for individual cancer patients.Although many molecular-targeted therapies for a number of actionable genomic alterations have been developed,the clinical application of such information is still limited to a small proportion of cancer patients.In this review,we summarize the current status of personalized drug selection based on genomic and molecular profiling and highlight the challenges how we can further utilize the individual genomic information.Cancer immunotherapies,including immune checkpoint inhibitors,would be one of the potential approaches to apply the results of genomic sequencing most effectively.Highly cancer-specific antigens derived from somatic mutations,the so-called neoantigens,occurring in individual cancers have been in focus recently.Cancer immunotherapies,which target neoantigens,could lead to a precise treatment for cancer patients,despite the challenge in accurately predicting neoantigens that can induce cytotoxic T cells in individual patients.Precise prediction of neoantigens should accelerate the development of personalized immunotherapy including cancer vaccines and T-cell receptor-engineered T-cell therapy for a broader range of cancer patients.

硫化钼是析氢反应(HER)有前途的电催化剂.S-或Mo物种均被认为是形成吸附氢触发HER反应的活性位,但Mo中心和S配体间相互作用的本质仍不清楚.另外,采用中性的水作为质子源用于产氢,来开发低成本的水裂解催化剂体系为研究者高度关注,但人们很少研究中性水条件下HER反应的机理.本文采用原位电化学Raman光谱对所合成的硫化钼中Mo–Mo和S–S物种在中性条件下的结构变化进行了监测.结果显示,归属于端位S–S物种的谱带随着和Mo–S振动谱带频率而同步变化,表明Mo–Mo键与端位S–S键起着协同作用,从而有利于氢气的生成.这可能是通过三核物种的内部重组而确认的.本文所揭示的HER反应中金属-配体相互作用的本质与作用表明了一个不同的反应机理,而以往的机理认为,S或Mo活性位独立起作用而促进HER反应的进行.

Practical applications and limitations of basalt discrimination diagrams

Big Earth Data 2023年第4期7卷 1081-1093页

作者： Kentaro nakamura Frontier Research Center for Energy and Resources(FRCER) School of EngineeringThe University of TokyoTokyoJapan

Determining the tectonic setting of unknown volcanic rocks continues to be one of the key challenges in geoscience.While discrimination diagrams have been successfully employed due to their ease of use,recently,validation with big data has raised questions about their performance.In this study,the discrimination boundaries of Th/Yb versus(vs.)Nb/Yb and TiO2/Yb vs.Nb/Yb diagrams,which are the most used types of discrimination diagrams,were redefined based on a large amount of compiled data and support vector machine,a machine learning method.The effectiveness of discrimination diagrams was verified,and the limitations and conditions when using them were clarified.The results show that when using the Th/Yb vs.Nb/Yb diagram,only basalts with Th/Yb ratios higher than the discrimination boundary can be identified as volcanic arcs in origin.In contrast,a significant overlap occurs across boundaries in other cases when using these diagrams,particularly for enriched samples with Nb/Yb ratios higher than five.Therefore,when using these diagrams to determine the tectonic setting of unknown samples,their limitations must be considered when interpreting their results.

World Journal of Gastroenterology 2014年第23期20卷 7298-7305页

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 by3-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.
