Volatile anesthetics impair hepatic tricarboxylic acid cycle function in adult and neonatal mice, with citrate accumulation driving a neonate-specific inhibition of beta-oxidation and ketosis through their increased relative sensitivity to malonyl-CoA.

Wide variation in cycle threshold (Ct) values from SARS-CoV-2 RT-PCR tests over calendar time offers the potential for their broader use in public testing programmes as an ‘early-warning’ system for shifts in infectious load and hence transmission.
Routine and campaign vaccination disruption in 2020 may lead to measles outbreaks and yellow fever burden increases in some countries, but is unlikely to greatly increase meningococcal A burden.
Two novel mutations in the GRIN2B gene reduce glutamate affinity by >1000-fold, reduce the receptors proton-sensitivity, and exert a dominant-negative effect over receptors in neurons.
Soluble Fas ligand interacts specifically with tumor necrosis factor receptor superfamily (TNFRSF)10B, also known as death receptor 5, exacerbating arthritis in a Fas-independent manner.
A new disposition mechanism for glucuronides, where liver serves as recycle organ and intestine serves as metabolism organ, is established to better explain the disposition of phenolics in vivo.
The TRPM4 ion channel has been identified as an important component in the causation of mechanical pressure overload-induced pathological left ventricular hypertrophy, which is a powerful predictor of cardiovascular mortality.
