By dawn or dusk—how circadian timing rewrites bacterial infection outcomes
FEBS Letters, EarlyView.The circadian clock shapes immune function, yet its influence on infection outcomes is only beginning to be understood. This review highlights how circadian timing alters host responses to the bacterial pathogens Salmonella enterica, Listeria monocytogenes, and Streptococcus pneumoniae revealing that the effectiveness of immune defense depends not only

An alternative method for the determination of siloxane activities toward basic equilibration catalysts [PDF]
Journal of the Serbian Chemical Society, 2005 The method used is based on the well-known fact that siloxane equilibrates once formed, do not change their compositions unless some siloxane compound is added, in which case new equilibrium compositions appear.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

FEBS Letters, EarlyView.Cryptochrome and PAS/LOV proteins play intricate roles in circadian clocks where they act as both sensors and mediators of protein–protein interactions. Their ubiquitous presence in signaling networks has positioned them as targets for small‐molecule therapeutics. This review provides a structural introduction to these protein families.

Selective glycerol transesterification over mesoporous basic catalysts
Comptes Rendus. Chimie, 2004 The preparation of monoglycerides from fatty methyl esters and glycerol can be carried out in the presence of acid or basic catalysts. Moreover, the use of porous and basic solid catalysts could induce a shape selectivity modifying the monoglyceride selectivity. Lauric (C12), myristic (C14) and stearic (C18) acid methyl esters were

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
