4植物中硝酸还原酶和亚硝酸还原酶的作用显示文摘植物通过硝酸盐同化途径以硝酸盐和氨的形式吸收氮元素。硝酸盐的同化是一个受到严格控制的过程,其中两个先后参加反应的酶——硝酸还原酶(NR)和亚硝酸还原酶(NiR)对初级氮的同化起主要调控。在高等植物中,NR和NiR基因的转录及转录后加工受到各种内在和外在因素的影响,翻译后调控是消除亚硝酸盐积累的重要机制。随着分子生物学技术的发展,可以更容易地通过突变体和转基因方式来研究NR和NiR基因的调控。May Sandar Kyaing 顾立江 程红梅 2011生物技术进展2011,1,3:68

8Prognostic significance of red blood cell distribution width in gastrointestinal disorders显示文摘The red blood cell distribution width(RDW) is a routinely measured and automatically reported blood parameter,which reflects the degree of anisocytosis. Recently,the baseline RDW was found to have clinical significance for assessing clinical outcome and severity of various pathological conditions including cardiovascular diseases,sepsis,cancers,leukemia,renal dysfunction and respiratory diseases. A myriad of factors,most of which ill-defined,have an impact on the red cell population dynamics(i.e.,production,maturation and turnover). A delay in the red blood cell clearance in pathological conditions represents one of the leading determinants of increased anisocytosis. Further study of RDW may reveal new insight into inflammation mechanisms. In this review,we specifically discuss the current literature about the association of RDW in various disease conditions involving the gastrointestinal and hepatobiliary systems. We also present some of the related measurements for their value in predicting clinical outcomes in such conditions. According to our data,RDW was found to be a valuable prognostic index in gastrointestinal disorders along with additional inflammatory biomarkers(i.e.,C reactive protein,erythrocyte sedimentation rate,and platelet count) and current disease severity indices used in clinical practice.Hemant Goyal Giuseppe Lippi Altin Gjymishka Bijo John Rajiv Chhabra Elizabeth May 2017World Journal of Gastroenterology2017,23,27:20
9Role of sex steroid receptors in pathobiology of hepatocellular carcinoma显示文摘The striking gender disparity observed in the incidence of hepatocellular carcinoma (HCC) suggests an important role of sex hormones in HCC pathogenesis. Though the studies began as early as in 1980s,the precise role of sex hormones and the significance of their receptors in HCC still remain poorly understood and perhaps contribute to current controversies about the potential use of hormonal therapy in HCC. A comprehensive review of the existing literature revealed several shortcomings associated with the studies on estrogen receptor (ER) and androgen receptor (AR) in normal liver and HCC. These shortcomings include the use of less sensitive receptor ligand binding assays and immunohistochemistry studies for ERα alone until 1996 when ERβ isoform was identified. The animal models of HCC utilized for studies were primarily based on chemical-induced hepatocarcinogenesis with less similarity to virus-induced HCC pathogenesis. However,recent in vitro studies in hepatoma cells provide newer insights for hormonal regulation of key cellular processes including interaction of ER and AR with viral proteins. In light of the above facts,there is an urgent need for a detailed investigation of sex hormones and their receptors in normal liver and HCC. In this review,we systematically present the information currently available on androgens,estrogens and their receptors in normal liver and HCC obtained from in vitro,in vivo experimental models and clinical studies. This information will direct future basic and clinical research to bridge the gap in knowledge to explore the therapeutic potential of hormonal therapy in HCC.Mamta Kalra Jary Mayes Senait Assefa Anil K Kaul Rashmi Kaul 2008World Journal of Gastroenterology2008,14,39:18

11Modeling and performance analysis of energy selective electron (ESE) engine with heat leakage and transmission probability显示文摘A model of an energy selective electron (ESE) engine with linear heat leakage and Lorentzian transmission probability is established in this paper.The expressions for the main performance parameters of the ESE engine operating as a heat engine or a refrigerator are derived by using the theory of finite time thermodynamics.The optimum performances of the ESE engine are explored and the influences of the heat leakage,the central energy level of the resonance,and the width of the resonance on the performance of the ESE engine are analyzed by using detailed numerical examples.The optimal operation regions of power output and efficiency (or cooling load and coefficient of performance (COP)) are also discussed.Moreover,the performances of the ESE engine with Lorentzian transmission probability are compared with those with rectangular transmission probability.It is shown that the power output versus efficiency (or cooling load versus COP) characteristic curves with and without heat leakage are all closed loop-shaped ones.The efficiency (or COP) of the ESE engine decreases as the heat leakage increases.It is found that as the resonance width increases,the power output and efficiency (or cooling load and COP) increase to a maximum and then decrease due to the finite range of energies which contribute positively to the power generation or refrigeration in the electron system.Especially,when heat leakage is taken into account,the characteristic curves of maximum efficiency (or maximum COP) versus half resonance width are parabolic-like ones,which are quite different from the monotonic decreasing characteristic curves obtained in previous analyses without considering heat leakage.The results obtained in this paper can provide some theoretical guidelines for the design and operation of practical electron energy conversion devices such as solid-state thermionic refrigerators.DING ZeMin,CHEN LinGen & SUN FengRui College of Naval Architecture and Power,Naval University of Engineering,Wuhan 430033,China Received December 24,2010 accepted May 30,2011 published online September 9,2011 2011Science China(Physics,Mechanics & Astronomy)2011,54,11:14

13Does playing a sports active video game improve object control skills of children with autism spectrum disorder?显示文摘Background: Active video games(AVGs) encourage whole body movements to interact or control the gaming system, allowing the opportunity for skill development. Children with autism spectrum disorder(ASD) show decreased fundamental movement skills in comparison with their typically developing(TD) peers and might benefit from this approach. This pilot study investigates whether playing sports AVGs can increase the actual and perceived object control(OC) skills of 11 children with ASD aged 6–10 years in comparison to 19 TD children of a similar age.Feasibility was a secondary aim.Methods: Actual(Test of Gross Motor Development) and perceived OC skills(Pictorial Scale of Perceived Movement Skill Competence for Young Children) were assessed before and after the intervention(6 × 45 min).Results: Actual skill scores were not improved in either group. The ASD group improved in perceived skill. All children completed the required dose and parents reported the intervention was feasible.Conclusion: The use of AVGs as a play-based intervention may not provide enough opportunity for children to perform the correct movement patterns to influence skill. However, play of such games may influence perceptions of skill ability in children with ASD, which could improve motivation to participate in physical activities.Jacqueline Edwards Sarah Jeffrey Tamara May Nicole J.Rinehart Lisa M.Barnett 2017Journal of Sport and Health Science2017,6,1:12
