Redox‐dependent binding and conformational equilibria govern the fluorescence decay of NAD(P)H in living cells

FEBS Letters, EarlyView.
In this work, we reveal how different enzyme binding configurations influence the fluorescence decay of NAD(P)H in live cells using time‐resolved anisotropy imaging and fluorescence lifetime imaging microscopy (FLIM). Mathematical modelling shows that the redox states of the NAD and NADP pools govern these configurations, shaping their fluorescence ...

Neutrophil deficiency increases T cell numbers at the site of tissue injury in mice

FEBS Letters, EarlyView.
In wild‐type mice, injury or acute inflammation induces neutrophil influx followed by macrophage accumulation. Mcl1ΔMyelo (neutrophil‐deficient) mice lack neutrophils, and in response to muscle injury show fewer macrophages and exhibit strikingly elevated T‐cell numbers, primarily non‐conventional “double‐negative” (DN) αβ and γδ T cells.

Functional role and folding properties of the glucan‐binding domain of oral bacterial glucansucrase

FEBS Letters, EarlyView.
The role of the glucan‐binding domain in Streptococcus sobrinus glucansucrase was examined, focusing on its impact on enzymatic activity, dextran binding, and structural stability of deletion mutants and a circularly permuted protein. Our research revealed that glucosyl transfer efficiency is linked to cooperative interdomain folding.

SYNTHESES, ANTIBACTERIAL AND ANTIFUNGAL ACTIVITIES OF 2-ARYL-4- QUINOLINE- CARBOXAMIDE DERIVATIVES [PDF]

Journal of Sciences, Islamic Republic of Iran, 1993
Reaction of aryl methyl ketone with isatin in the presence of a base afforded 2- arylquinoline-4-carboxylic acid (3). Reaction of diazomethane with compound 3 yielded the ester 4. Compound 5 was prepared from the reaction of N, N'-dialkylethyl (or propyl)

Optimized Method for the Synthesis of Alkyne-Modified 2′-Deoxynucleoside Triphosphates

Molecules
A general approach is presented for synthesizing alkyne-modified nucleoside triphosphates via the Sonogashira cross-coupling reaction of unprotected halogenated 2ʹ-deoxynucleoside, followed by monophosphorylation and the reaction of the corresponding ...

The cytochrome oxidase defect in ISC‐depleted yeast is caused by impaired iron–sulfur cluster maturation of the mitoribosome assembly factor Rsm22

FEBS Letters, EarlyView.
The yeast mitoribosome assembly factor Rsm22 contains a [4Fe‐4S] cluster that is matured by the mitochondrial iron–sulfur cluster assembly (ISC) machinery. Defects in ISC components result in impaired mitochondrial protein synthesis due to a mitoribosome assembly defect.

Ergothioneine supplementation improves pup phenotype and survival in a murine model of spinal muscular atrophy

FEBS Letters, EarlyView.
Spinal muscular atrophy (SMA) is a genetic disease affecting motor neurons. Individuals with SMA experience mitochondrial dysfunction and oxidative stress. The aim of the study was to investigate the effect of an antioxidant and neuroprotective substance, ergothioneine (ERGO), on an SMNΔ7 mouse model of SMA.
