最近的证据表明，在动物模型中，肠道病理学和微生物组与高血压之间存在联系。然而，这种关联在人类中是否存在尚不清楚。因此，该研究的目的是检验高血压患者具有明显特异的肠道微生物组以及肠上皮屏障功能标记物和微生物组组成可以预测收缩压变化的假设。研究者通过鸟枪法宏基因组学分析粪便样本显示微生物分类和功能变化，结果显示高血压患者和对照受试者之间丁酸盐产生存在差异。

神经炎症的一个主要标志是小胶质细胞和星形胶质细胞的激活以及炎症介质(如IL-1β、TNF-α、iNOS和IL-6)的诱导。神经炎症会导致从急性中枢神经系统创伤到慢性神经退行性疾病等多种神经系统疾病的进展。mRNA稳定性的转录后调控途径和翻译效率是这些炎症介质表达的主要驱动因素。这一调节水平的一个共同元素以富含腺嘌呤和尿苷的元素(ARE)为中心,该元素存在于编码这些炎症介质的mRNA的3’非翻译区(UTR)中。(ARE)-结合蛋白(AUBPs)——如人类抗原R(HuR)、三四脯氨酸(TTP)和KH型剪接调节蛋白(KSRP)——是指导这些转录后通路的关键节点,可以促进(HuR)或抑制(TTP和KSRP)胶质细胞产生炎症介质。本综述将讨论ARE介导的RNA调节的基本概念及其对胶质细胞驱动的神经炎症性疾病的影响。还将讨论针对这种新的基因调控水平以达到治疗效果的策略,并对其治疗神经系统疾病潜力的初步研究进行回顾性分析。

A serological survey of Toxoplasma gondii was conducted using LAT (Latex Agglutination Test) on 205 sera collected from working horses and donkeys in Khartoum State, Sudan. The overall sero-prevalence of the investigated equines was 32.7%. Antibodies to T. gondii were found in 38% of 100 horses and 27.6% of 105 donkeys. The titers were 1 2 (4 heads), 1 4 (11 heads), 1 8 (13 heads), 1 16 (17 heads), 1 32 (5 heads), 1 64 (10 donkeys) and 1 128 (7 donkeys). Neither the area nor animal species showed significant differences between the investigated groups. However, age was reported to show significant (P < 0.05) effect on equine toxoplasmosis in the Sudan. This is the first report on equine toxoplasmosis in the Sudan.
