[Abstract]  Control of bacterial adhesions to a substrate with high precision in space and time is important to form a well-defined biofilm. Here, we present a method to engineer bacteria such that they adhere specifically to substrates under blue light through the photoswitchable proteins nMag and pMag. This provides exquisite spatiotemporal remote control over these interactions. The engineered bacteria express pMag protein on the surface so that they can adhere to substrates with nMag protein immobilization under blue light, and reversibly detach in the dark. This process can be repeatedly turned on and off. In addition, the bacterial adhesion property can be adjusted by expressing different pMag proteins on the bacterial surface and altering light intensity. This protocol provides light ... [摘要]  在空间和时间上高精度地控制细菌粘附到基底对于形成明确的生物膜是重要的。 在这里,我们提出了一种方法来设计细菌,使其在蓝光下通过光可切换蛋白质nMag和pMag特异性地粘附在基底上。 这为这些交互提供了精妙的时空遥控。 工程菌在表面上表达pMag蛋白,以便它们可以在蓝光下与nMag蛋白固定化的基质粘附,并在黑暗中可逆地分离。 该过程可以重复开启和关闭。 此外,通过在细菌表面表达不同的pMag蛋白质并改变光强度可以调节细菌粘附性质。 该协议提供了可高度空间和时间分辨率的细菌粘附的光可切换,可逆和可调控制,这使我们能够以极大的灵活性在基底上图案化细菌。

【背景】控制生物膜形成对于了解细菌在自然发生的生物膜中的社会相互作用至关重要(Flemming et。,2016)。这对生物膜在生物催化,生物传感和废物处理中的生物技术应用也特别重要(Zhou等人,2013; Jensen等人,2016)。生物膜的形成始终始于细菌与底物的粘附,这决定了生物膜中的空间组织(Liu等人,2016; Nadell等人,2016)。已经提出了许多策略来控制细菌粘附,例如通过脂质体融合利用生物正交反应基团修饰细菌表面(Elahipanah等,2016),将粘附分子固定在基质上(Sankaran等,等),2015; Zhang等人,2016; ...

In vitro Studies: Inhibition of Nevirapine Metabolism by Nortriptyline in Hepatic Microsomes

[Abstract]  One of the most prevalent and interfering psychosocial comorbidities of HIV infection is clinical depression (22 to 45%). For this reason, a study of a possible interaction between the nonnucleoside reverse transcriptase inhibitor nevirapine (NVP) and the tricyclic antidepressant nortriptyline (NT) was carried out. In vitro studies with rat and human hepatic microsomes showed a marked inhibition of NVP metabolism by NT being more intense in rat than in human. The extrapolation of these results to humans suggests increased NVP side effects when both drugs are coadministered, but additional in vivo human studies are required to evaluate the clinical implication of this interaction.

This protocol describes a technique for detecting and measuring the inhibition of ...
[摘要]  HIV感染的最普遍和干扰的心理社会共病是临床抑郁症(22%至45%)。 为此,进行了非核苷逆转录酶抑制剂奈韦拉平(NVP)和三环抗抑郁药去甲替林(NT)之间可能的相互作用的研究。 使用大鼠和人肝微粒体的体外研究显示在大鼠中NT比在人中更强烈的NVP代谢的显着抑制。 将这些结果外推到人表明当两种药物共同给药时,NVP副作用增加,但是需要另外的体内人体研究来评价这种相互作用的临床意义。
该方案描述了 检测和测量肝微粒体中去甲替林对奈韦拉平代谢的抑制的技术。
