取自怀俄明州泡德河盆地海兰德铀矿采场的样品含有有机碳、硫化物和铀。数据表明,有机碳和硫,硫和铀间具明显的相关性,而铀和有机碳没有相关性,说明卷状矿床中硫化物是铀的富集剂,而有机碳(可能是外来的)仅为硫酸盐还原细菌的一种能源。

OBJECTIVE: To explore racial differences in reporting of early postpartum depressive symptoms. To explore whether racial differences in early postpartum experience (such as mother’s health status and social context) might account for racial differences in reported postpartum depressive symptoms. METHODS: This was a telephone survey of 655 white, African- American, and Hispanic mothers between 2 and 6 weeks postpartum. Mothers reported on demographic factors, physical symptoms, daily function, infant behaviors, social support, skills in managing infant and household, access, and trust in the medical system. We explored racial differences in report of early postpartum depressive symptoms using bivariate and multivariate statistics. RESULTS: African- American and Hispanic women more commonly reported postpartum depressive symptoms (43.9% and 46.8% , respectively) than white women (31.3% , P ed with early postpartum depressive symptoms in white, African- American, and Hispanic mothers. In a comprehensive model including other demographic factors, history of depression, physical symptoms, daily function, infant behavior, social support, skills in managing infant and household, access, and trust, the adjusted odds ratio for reported postpartum depressive symptoms remained elevated for AfricanAmerican- women at 2.16 (95% confidence interval 1.26- 3.70) and Hispanic women at 1.89 (95% confidence interval 1.19- 3.01) as compared with white women. CONCLUSION: African- American and Hispanic mothers are at higher risk for reporting early postpartum depressive symptoms as compared with white mothers. Factors associated with these symptoms are similar among African- American, Hispanic, and white mothers.

Middle Temporal Area（MT/V5）在视觉运动处理过程中起着重要作用。MT区的神经元对物体的运动属性如运动的方向和运动速率等具有很强的选择性,而这些选择性被认为是运动知觉的神经基础。很多实验表明在正常老化过程中,人类的运动知觉呈现出不同程度的衰退。其具体表现为老年人对运动刺激的运动方向和运动速度的检测判别能力下降,对视觉信号的分析和提取速度显著下降,反应延迟明显增长。然而视觉系统光学部分的衰退并不能完全解释这些运动知觉功能的下降。尽管目前普遍认为老化会引起视觉中枢的生理学变化,但其影响视觉功能的潜在神经机制却知之甚少。我们先前的实验结果表明老年猕猴的初级视皮层和次级视皮层细胞都出现了功能性衰退。为了进一步了解运动知觉的衰老机制,我们采用单细胞记录技术在麻醉麻痹猕猴的V1区和MT区研究了细胞在正常老化过程中发生的方向选择性的变化。实验结果表明:1.和青年猕猴相比,老年猕猴MT区的PDS（pattern direction selective）细胞在全部细胞中所占的比例显著下降;2.在老年猕猴的MT和V1区,细胞的方向选择性发生了显著性的降低;3.方向性选择性的衰退在MT区的各类细胞中均有发生,和CDS（component direction selective）细胞相比,PDS细胞的方向选择性受老年化的影响更为严重;4.方向选择性的衰退伴随着细胞的诱发和自发反应都增加而发生;5.相对于诱发发放,自发发放增加得更多,从而导致了信噪比在老年猕猴MT区显著降低;6.用双因素方差分析发现,老年化引起的MT细胞功能性退化更甚于V1区的退化。这些实验结果表明在正常的衰老过程中,MT细胞发生了功能性衰退。结合我们以前在V1、V2区的工作,本结果还表明沿着视觉信息处理的背侧通路向上,衰老可能是逐级累积的。

为规范描述肾功能和疾病的专业术语,2019年6月改善全球肾脏病预后组织(KDIGO)召开共识会议,对肾脏功能和疾病、肾衰竭、急性肾脏病和急性肾损伤、慢性肾脏病及肾脏评估共5个部分的内容制定了相应的术语表,并就以下建议达成共识。①对于肾脏功能和疾病的一般描述,使用术语“kidney”,而不使用“renal”或前缀“nephro-”;②使用“肾衰竭(kidney failure)”并适当描述是否存在相应症状、体征和治疗,而不是“终末期肾脏疾病(end-stage kidney disease)”;③使用KDIGO对急性肾脏病(AKD)和急性肾损伤(AKI)进行定义和分类;④使用KDIGO对慢性肾脏病(CKD)进行定义和分类;⑤使用特定的肾脏检测指标,例如蛋白尿或肾小球滤过率(GFR)降低,而不是肾功能“异常(abnormal)”或“降低(reduced)”来描述肾脏结构和功能的改变。文章简要总结会议的主要讨论。
