The Role and Mechaninsm study of IL-20-related Cytokines contribute to Autoimmune Myocarditis in Mice [PDF]

open access: yes, 2015
目的:免疫相关因素与心肌炎引起的心肌纤维化密切相关。前期研究表明,IL-10家族成员在心肌炎慢性期心肌纤维化的形成过程中发挥重要作用。IL-20是最新发现的IL-10家族成员之一,具有调节细胞增殖和分化的作用。但IL-20是否参与心肌炎心肌纤维化过程尚不清楚。本课题通过实验探讨IL-20及其相关因子对小鼠自身免疫性心肌炎(EAM)心肌纤维化的影响及可能的分子调节机制。 方法:利用小鼠心肌肌球蛋白多肽MyHC6l4-629和完全弗氏佐剂充分混合后,于第0天和第7天皮下注射建立小鼠EAM模型;组织切片H ...

Non‐Precious Metals Enhance Hydrogen Evolution in COF/Cd0.9Cu0.1S S‐Scheme Heterojunctions: KPFM Reveals Charge Transfer Pathways

open access: yesRare Metals, EarlyView.
ABSTRACT Photocatalytic hydrogen production from water splitting is a promising strategy for sustainable and clean energy generation. However, the design of low‐cost, highly active photocatalysts remains a critical challenge. In this study, covalent organic frameworks (COFs) were loaded onto the surface of Cd0.9Cu0.1S to fabricate COF/Cd0.9Cu0.1S ...

Activation of Latent HIV-1 by Marine Shellfish Toxins [PDF]

open access: yes, 2016
高效抗逆转录病毒疗法(HAART)是目前治疗艾滋病最可靠的方法,HAART可以通过药物联用的方法有效的降低艾滋病感染者的死亡率,但由于HIV的潜伏感染,HAATR疗法并不能将HIV病毒从体内完全清除,患者体内的HIV病毒潜伏库是彻底治愈艾滋病的巨大挑战。随着“ShockandKill”的治疗新策略的提出,通过激活潜伏期HIV病毒库进而根除潜伏病毒,从而实现艾滋病的彻底根治。因此寻找高效低毒HIV潜伏激活剂具有重要的科学意义和应用价值。 本研究基于J ...

The Chinese Shareholders' Risk Analysis and Prevention Mechanism [PDF]

open access: yes, 2016
公司股东,即公司的出资人,俗称投资人。现实中,股东往往只看到了其对公司享有的权益,而忽视其对公司所承担的责任和义务。事实上,股东对公司享有权益的同时亦承担着风险。股东风险来源于股东自身承担的责任和义务以及股东关系人。股东应了解其风险并形成风险防范意识,建立风险防范机制,否则,股东权益将可能落空。 本文以股东利益相关者为主线,通过多个真实、具体案例对中国公司股东的风险现状进行分析,对股东风险进行系统性的梳理,从而找出股东的风险来源,进而作深入的论述并提出解决方法 ...
