  Optimism and depression as predictors of physical and mental health functioning: The normative aging study

  摘要：

  Dispositional optimism has been linked in previous studies to better health outcomes. We sought to examine the independent associations of dispositional optimism and depressive symptoms with physical and mental functioning in a cohort of healthy middle-aged and older men. The study was conducted among 659 subjects in the Veterans Administration (VA) Normative Aging Study. Dispositional optimism and depressive symptomatology were measured in 1991 and 1990, respectively, by the Life Orientation Test and the Center for Epidemiologic Studies-Depression Scale (CES-D). The dependent variables, functioning and well-being, were measured in 1992 by the Medical Outcomes Study Short-Form Health Survey (SF-36). In multivariate regression models, optimism was associated with higher levels of general health perceptions, vitality, and mental health, and lower levels of bodily pain, but not to physical functioning, social functioning, or role limitations due to physical or emotional problems. Depressive symptomatology was associated with reduced levels of functioning across all SF-36 domains. The findings for optimism and depression were statistically significant after mutual adjustment in multivariate regression models. Optimism and depression are independent predictors of functional status among aging men.

  摘要：

  1,2,4-恶二唑是一种杂环化合物，具有广泛的反应活性和许多有用的应用。通常使用分子氢还原反应性ON键以获得脒衍生物。NH 4 CO 2 H-Pd/C在这里被证明是一种新的ON还原系统，使我们能够获得不同取代的酰基脒、酰基胍和二酰基胍衍生物。该系统还可有效实现 5-(2'-氨基苯基)-1,2,4-恶二唑还原重排为 1-烷基喹唑啉-4(1 H )-酮。生物碱糖苷也用此方法获得。初步测试了所得化合物的细胞毒性、诱导氧化应激、α-葡萄糖苷酶和 DPP4 抑制等生物活性，显示出作为抗糖尿病药物的潜在应用。

  日期：——

  A mild and efficient method for the synthesis of 3-amino-5-aryl-1,2,4-oxadiazole by intramolecular cyclization using PhI(OAc)2 (PIDA) as an oxidant is developed. Various 3-amino-5-aryl-1,2,4-oxadiazoles are prepared in moderate to good yields, and the PIDA-mediated N–O bond formation mechanism is suggested. In view of the readily available starting materials, operational simplicity, high functionality

  Guanidin-Verbindungen der Formel III mit X(2) mit den in den Ansprüchen angegebenen Bedeutungen dienen zum Herstellen von wertvollen antiarrhythmischen Arzneimitteln mit cardioprotektiver Komponente zur Infarktprophylaxe und der Infarktbehandlung sowie zur Behandlung der angina pectoris hervorragend geeignet, wobei sie auch präventiv die pathophysiologischen Vorgänge beim Entstehen ischämisch induzierter Schäden, insbesondere bei der Auslösung ischämisch induzierter Herzarrhythmien, inhibieren oder stark vermindern. Wegen deren schützender Wirkungen gegen pathologische hypoxische und ischämische Situationen können diese Verbindungen infolge Inhibition des zellulären Na +/H +-Austauschmechanismus als Arzneimittel zur Behandlung aller akuten oder chronischen durch Ischämie ausgelösten Schäden oder dadurch primär oder sekundär induzierten Krankheiten verwendet werden.
