Homocysteinemia and Depression in community-Dwelling Older Adults: The cohort Longitudinal Study “InveceAb” (Brain Aging in Abbiategrasso)

Health 2024年第1期16卷 22-36页

Depression is a major health problem, especially for elderly people. According to the “homocysteine hypothesis of depression”, high homocysteine levels may cause depression of mood via cerebrovascular diseases. Whilst biologically plausible, such hypothesis needs yet confirmation. We aimed at: 1) studying the relationships between homocysteinemia (HcY) and depression in a community-dwelling cohort of people aged 70 to 75 years at baseline;2) investigating plasma levels of HcY and 3) comparing these levels between males and females, in the same population. We exploited the data from four waves (2010, 2012, 2014 and 2018) of the longitudinal study “InveceAb”, with specific regard towards mood assessment, by Geriatric Depression Scale (GDS) scoring, and diagnosis of clinically relevant or subthreshold depression. HcY plasma levels were measured in the waves 2012, 2014 and 2018. Sample attrition was due mainly to death or overall worsening. No statistically significant differences were found in plasma homocysteine levels in each wave, according to depressive symptoms. No correlations were found between plasma HcY levels in each wave with their corresponding GDS scores, even after adjustment for folate and cobalamin blood concentrations. Dichotomized levels of HcY (≤15 vs >15 μM/l) were not associated with dichotomized GDS scores (≤4 vs higher), clinically relevant and subthreshold depression diagnosis and any antidepressive use, in any wave. First (2012) HcY levels increased with participants’ increasing age, cross-sectionally. Listwise HcY concentrations decreased along the 3 waves. HcY levels were always higher in males than in females. Our results may challenge the “homocysteine hypothesis” of depression, whilst supporting the role of high homocysteinemia as a marker of overall bad health.

自2002年christe等首次对五唑阴离子(cyclo-N5^-)进行质谱检测以来,这个唑类的最新成员就受到了越来越多的关注。由于不含碳和氢,cyclo-N5^-可以释放大量能量,同时分解为对环境友好的氮气。由于这些吸引人的特性,cyclo-N5^-和相关化合物对于高能密度材料(high-energy-densitymaterial,HEDM)研究的发展至关重要。本文旨在提供有关cyclo-N5^-的所有研究的综合报告,重点是作为高能材料的cyclo-N5^-及其实验合成。本文包括以下内容:①cyclo-N5^-的历史意义:②cyclo-N5^-的前驱体;③以芳基五唑前驱体为重点的cyclo-N5^-合成路线:④影响cyclo-N5^-的稳定性的因素;⑤目前含能cyclo-N5^-化合物的高能性能:⑥未来有潜力的实验研究。本文全面总结了当前人们对cyclo-N5^-的了解,旨在进一步了解这种阴离子作为下一代强大而环保的炸药的潜力。

罗马尼亚曾是欧洲通往土耳其帝国的要道,在这片土地上,古典与现代有着完美的结合。我没有流连于恢弘的古堡和蜿蜒的多瑙河,而是在偏远的Maramures地区花了整整一年时间,拍摄当地人最本真的生存,体验那些在21世纪即将消亡的罗马尼亚文化风俗。没有其他任何一个地方,能让我如此深入地观察着冬季的逝去、春天的到来,四季缓慢循环,周边不乏干枯与死亡,但更能感受到来自男人、女人、动物以及土地的生命脉动。这些照片,是在西方消费社会和全球化的脚步到来之前,属于罗马尼亚的最后一首抒情诗。
