FEBS Letters, EarlyView.Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Synergistic Mn/N/F Tri-Doped TiO2 Nanoparticles: Bandgap Narrowing and Defect Passivation for Solar-Driven Pollutant Degradation [PDF]
Iranian Journal of Chemistry & Chemical EngineeringThe persistent challenge of organic pollutant remediation demands efficient solar-driven photocatalysts. Titanium dioxide (TiO2), though widely used, suffers from a wide bandgap (~3.2 eV), limiting activity to UV light and rapid charge recombination ...

Artificial molecular machines and motors—Design and control of nanoscale motion
FEBS Letters, EarlyView.Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

FEBS Letters, EarlyView.Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers
Molecular Oncology, EarlyView.The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Cogent Food & AgricultureLarge quantities of defatted grape seed meal (DGSM) are discarded annually in the grape pomace industry. This residue could be exploited as a new source of non-animal protein to improve the chemical and color stabilization of red wines from warm regions.

Proceedings of the National Academy of Sciences, 1931 In another paper, L,3 the author has given a proof of a formula for M(λ), the number of ways of coloring a graph in λ colors, due to Birkhoff. The numbers m ij , in terms of which M(λ) is expressed, are here studied in detail; a method of calculating them is given.

Distribution of colors in Gallai colorings
European Journal of Combinatorics, 2020 A Gallai coloring is an edge coloring that avoids triangles colored with three different colors. Given integers $e_1\ge e_2 \ge \dots \ge e_k$ with $\sum_{i=1}^ke_i={n \choose 2}$ for some $n$, does there exist a Gallai $k$-coloring of $K_n$ with $e_i$ edges in color $i$?
