High HIV prevalence in Sub-Saharan African (SSA) in men who have sex with men (MSM) leads to greater risk for their wives and other steady female partners because of prolonged exposure. To provide insights into the context possibly contributing to the risk of HIV transmission from MSM to women, our mixed-method synthesis about MSM' marriage and steady relationships with cisgender women aimed to: (i) assess the extent of engagement in steady relationships with women and in risky behaviors with these women across SSA's four regions; (ii) explore the underlying dynamics within these relationships by gathering qualitative information. We used quantitative and qualitative data specifically pertaining to related to marriage or other steady relationships with women from a systematic review on men who have sex with both men and women (MSMW) in SSA (PROSPERO-CRD42021237836).

Delays in mitosis trigger p53-dependent arrest in G1 of the next cell cycle, thus preventing repeated cycles of chromosome instability and aneuploidy. Here we show that MDM2, the p53 ubiquitin ligase, is a key component of the timer mechanism triggering G1 arrest in response to prolonged mitosis. This timer function arises due to the attenuation of protein synthesis in mitosis.

The F domain of FF-ATP synthases/ATPases (FF) possesses three catalytic sites on the three αβ interfaces, termed αβ, αβ, and αβ, located mainly on the β subunits. The enzyme also has three non-catalytic ATP-binding sites on the three αβ interfaces, located mainly on the α subunits. When ATP does not bind to the non-catalytic site, FF becomes significantly prone to ADP inhibition, ultimately resulting in the loss of ATPase activity.

Tacrolimus is extensively used for the prevention of graft rejection following solid organ transplantation in pregnant women. However, knowledge gaps in the dosage of tacrolimus for pregnant patients with different CYP3A5 genotypes and infection conditions have been identified. This study aimed to develop a pregnant physiologically based pharmacokinetic (PBPK) model to characterize the maternal and fetal pharmacokinetics of tacrolimus during pregnancy and explore and provide dosage adjustments.
