The viral genomics, host cellular factors, and interactions are critical for establishing a viral infection and developing a related disease. This paper aims to provide an overview of viral genomics and discuss host cellular factors so far identified to be involved with the disease susceptibility. The novel pathogen is a beta coronavirus and one of seven that cause diseases to humans. It is a single strand positive-sense RNA genome virus that encodes 27 proteins, including the structural Spike protein that binds to host cell surface receptors and is a key for viral entry, and 16 nonstructural proteins play a critical role in viral replication and virulence. While the angiotensin-converting enzyme, ACE2 receptor, and the proteases TMPRSS2 and furin are established as necessary for viral entry, host factors CD147, Cathepsins, DPP4, GRP78, L-SIGN, DC-SIGN, Sialic acid, and Plasmin(ogen) may also play a role in the viral entry. The Spike protein and nonstructural proteins, and various host factors working together may contribute to the infection kinetics, high infectivity, rapid transmission, and a spectrum of clinical manifestations of COVID-19. More importantly, they can serve as potential targets in developing strategies for therapeutical prevention and intervention.","PeriodicalId":265939,"journal":{"name":"Global Clinical and Translational Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130586895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

All patients were treated with risperidone for eight weeks. Positive and Negative Syndrome Scale (PANSS) was evaluated, and serum levels of S100B and parameters of oxidative stress including total oxidative status (TOS) and malondialdehyde (MDA) were measured before and after antipsychotic treatment. A general linear random-effect model was used for data analysis.\u0000\u0000Results: Antipsychotic treatment with risperidone reduced the levels of S100B significantly in the first episode drug-naive patients with schizophrenia (Beta=24.89; p=0.0087) and marginally in the drug-free acute phase (Beta=15.65; p=0.093), no significant difference in the effect on S100B between patient groups (p=0.4785). In contrast, antipsychotic treatment increased the levels of MDA in drug-free acute phase schizophrenia (Beta=-6.55; p<0.0001) but not in the first episode drug-naive patients (beta=-0.57; p=0.6631); the effects on MDA were significantly different between two patient groups (p=0.0020). We found that the levels of S100B were only associated with the PANSS negative score in the drug-free acute phase patients who were treated with antipsychotics.\u0000\u0000Conclusion: Antipsychotic treatment with risperidone reduced the levels of S100B in first-episode, drug-naive patients with schizophrenia, but may increase the levels of MDA in drug-free acute phase schizophrenia.","PeriodicalId":265939,"journal":{"name":"Global Clinical and Translational Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128586759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Social Network and Functional Health Status among the Elderly","authors":"Yun Zhang, Hong Zhang","doi":"10.36316/gcatr.01.0016","DOIUrl":"https://doi.org/10.36316/gcatr.01.0016","url":null,"abstract":"Background: In the absence of adequate public pension benefits, the older people in China have to rely on their social networks for old-age support. However, few empirical studies have been carried out to examine the pattern of social network and their impact on elderly health in China.\u0000\u0000Methods: Using the data set from two waves of the Chinese Longitudinal Healthy Longevity Survey (CLHLS) conducted in 2008 and 2014, we examined the characteristics of social network types and their impacts on the health status among the elderly. The dependent variables included the measures of self-rated health (SRH), activities of daily living (ADL), instrumental activities of daily living (IADL), and cognitive score (MMSE). K-means clustering method was used to construct the social network type, which was the primary factor we were interested in examining for association with functional health status. A random-effect regression model was utilized to control for the clustering effects within the observations over time.\u0000\u0000Results: Four types of the social network were derived among the older people, and they were the diverse network (6.65%), family-focused network (32%), children-focused network (29.89%) and restricted network (31.45%). Compared with the restricted network, the diverse network was associated with the best functional health status and self-rated health among the elderly; the family-focused network was also associated with a better score of ADL, IADL, and MMSE but not significantly with SRH score; and the children-focused network was also associated with a better health status of all measures. Furthermore, social support from family members and friends positively influenced the health status of the elderly. In contrast, having social workers available when needed was associated with the reduced ADL, IADL, and SRH scores. This might be due to that those elderly with the worst health status are in a greater need for support from social workers, and hence, the reverse association may occur.\u0000\u0000Conclusion: family- and children-focused network were primary types among the older people in China. Consistent with previous studies, while the diverse network was most beneficial for the functional health status in multiple measures, it only accounted for a small proportion; people with the restricted network had the worst health status.","PeriodicalId":265939,"journal":{"name":"Global Clinical and Translational Research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127951622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
