从脂肪组织的内分泌功能角度探讨其在慢性阻塞性肺疾病中的作用机制研究

脂肪组织除了通过其力学特征或机械功能对周边组织器官产生影响以外,还可以凭借非物理性的内分泌功能通过脂肪因子输出信号方式有效地建立起与呼吸系统等远程器官的互作信息网络,进而参与多种肥胖相关疾病的发生与发展。作为内分泌领域的突破性进展之一,脂肪组织的内分泌功能受到生命科学领域的关注。近年来,多项流行病调查研究揭示了肥胖是造成慢性阻塞性肺疾病（COPD）等呼吸系统疾病肺功能损害重要的危险因素。基于此,本文将分别梳理脂联素、瘦素、内脂素等脂肪因子在COPD中的作用机制,从脂肪组织内分泌功能角度为COPD的防治研究提供新思路。     

Adult adjustment of persons with severe/profound mental disabilities: A longitudinal study

The parents of 14 individuals with severe/profound mental disabilities were interviewed one and three years after their children graduated or aged out of high school. Two categories of information were sought concerning the adult adjustment of these individuals. General status variables included marital status, place of residence, agencies contacted concerning employment opportunities, financial resources, leisure activities, means of transportation, sources of help in resolving problems, and amount of postsecondary training. Employment variables included location of employment, wages, number of hours worked per week, and job benefits received. Results indicated that three years after exiting high school, all participants were very dependent upon others for housing, transportation, and financial assistance. Ten of the 14 individuals were employed 3 years after exiting high school, all in sheltered workshops.     

医学生人格特征形成的相关性研究

目的分析影响医学生人格特征形成的相关因素，为发展大学生的人格特征探寻其理论依据。方法用EPQ量表对601名医学生进行团体测验，其数据在WJZ心理测验软件上预处理后转入电子表格，用SPSS11．0软件进行统计学分析。结果EPQ量表中E、N、P、L的均值、标准差与常模比较，其差异有统计学意义；E，P，L3个维度间有不同程度的相关性：当以EPQ为因变量，15个影响因素为自变量进行逐步回归分析时，进入回归方程的主要是人际关系、家庭、学校教养(育)方式、经济状况、身心伤害否及自我形象、才能、专业的满意度。结论医学生的人格特征还处于发展阶段，其形戍过程与上述因素密切相关。     

Ribosomal control of translational fidelity in Podospora anserina: A suppressor and an antisuppressor affecting the paromomycin-induced misreading in vitro

Summary The hypersensitivity to paromomycin dis played by the su _1–60 suppressor, which was thought to be a ribosomal ambiguity mutation, was used to isolate a new antisuppressor, AS ₇₁. This antisuppressor is not specific for ribosomal suppressors, since it is able to act on putative tRNA-type suppressors. Compared to the wild-type, the AS _7-1 mutation produces an increased resistance to paromomycin. In addition, it was found to stop the sporulation process. In the polyuridylic acid-dependant assay, the paromomycin induced misreading was shown to be higher on su _1–60 ribosomes and lower on ribosomes from AS _7–1 mutant and AS _7S-1-su _1–60 double mutant than on wild-type ribosomes. These data confirm that su _1–60 and AS _7-1 mutants are ribosomal mutants involved in the control of translational fidelity.     

The Turner syndrome research registry: Creating equipoise between investigators and participants

To address knowledge gaps about Turner syndrome (TS) associated disease mechanisms, the Turner Syndrome Society of the United States created the Turner Syndrome Research Registry (TSRR), a patient‐powered registry for girls and women with TS. More than 600 participants, parents or guardians completed a 33‐item foundational survey that included questions about demographics, medical conditions, psychological conditions, sexuality, hormonal therapy, patient and provider knowledge about TS, and patient satisfaction. The TSRR platform is engineered to allow individuals living with rare conditions and investigators to work side‐by‐side. The purpose of this article is to introduce the concept, architecture, and currently available content of the TSRR, in anticipation of inviting proposals to utilize registry resources.
