Elimination of acrolein from cider by addition of sulphur dioxide

Journal of Chemical Technology &Biotechnology, Volume 101, Issue 6, Page 1254-1262, June 2026.
Abstract BACKGROUND Acrolein is a toxic substance that sometimes appears in ciders, imparting an unpleasant taste and odour, which spoils the beverage entirely. Based on the reaction between acrolein and sulphur dioxide to form adducts, some oenologists of the Basque Country and Navarre (Northern Spain) use sulphur dioxide to remove acrolein.

Tetrameric hotdog‐fold structure and catalytic mechanism of the SaPaaI thioesterase from Staphylococcus aureus

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Acyl‐CoA thioesterases hydrolyse thioester bonds to release free fatty acyl chains and coenzyme A (CoA), thereby regulating lipid metabolism, signaling, and membrane homeostasis. Here, we present the structural and functional characterization of the Paal‐like thioesterase SAV0944 (SaPaaI) from Staphylococcus aureus.

The Arsenal of Aromatic Degrading Bacteria: How They Sense, Chase, Adapt and Destroy Environmental Pollutants

Microbial Biotechnology, Volume 19, Issue 5, May 2026.
In the environment, bacteria sense aromatic pollutants, migrate toward them, adapt to toxicity, and deploy specialized uptake and catabolic systems. Genomic plasticity, metabolic versatility and division of labor within populations together aid in the degradation of persistent aromatics, highlights that biodegradation is driven by various eco ...

Bed rest decreases resting skeletal muscle O2 uptake and resting energy expenditure in young and elderly subjects

Experimental Physiology, Volume 111, Issue 5, Page 2599-2612, 1 May 2026.
Abstract A decrease in resting muscle O2 uptake (V̇O2m${\dot V_{{{\mathrm{O}}_2}{\mathrm{m}}}}$) described during bed rest (BR) could determine a decreased whole‐body resting energy expenditure (REE), potentially useful during prolonged spaceflights. Two groups of recreationally active men (young [Y], n = 8, age 23 ± 5 years; elderly [E], n = 10, age ...

Spectral and Thermal Studies of Light Lanthanide Complexes with 4-Methoxy-3-nitrobenzoic Acid [PDF]

, 1999
4-Methoxy-3-nitrobenzoates of light lanthanides with a metal to ligand ratio of 1:3 have been obtained as hydrated salts. They have colours typical of Ln3+ ions (Pr-green, Nd-pink, Sm-cream, and La, Ce, Eu and Gd-white).

Synthesis of p‐Coumarates With Potential Anti‐Alzheimer's Action: Enzyme Inhibition and In Silico Studies

Chemistry &Biodiversity, Volume 23, Issue 4, April 2026.
ABSTRACT Alzheimer's disease (AD) is a fatal neurodegenerative disorder that affects cognition, memory, and behavior. Such a disease is considered the most common cause of dementia and affects a large portion of the elderly population worldwide. Currently, cholinesterase inhibitors are used to reduce the symptoms and rate of progression of this disease.

Research advances in the applications of mitochondria‐targeted cyanine dyes in imaging

VIEW, Volume 7, Issue 2, April 2026.
Near‐infrared (NIR) fluorescence imaging, a novel non‐invasive diagnostic tool, plays a crucial role in the imaging and monitoring of solid tumors. At its core are NIR fluorescent dyes, which are widely utilized due to their ability to minimize tissue autofluorescence interference, thereby significantly enhancing the signal‐to‐noise ratio (SNR) and ...

Crystal Structure of L-Histidinium 2-Nitrobenzoate [PDF]

Journal of Amino Acids, 2012
A new nonlinear optical organic compound, namely, L-histidinium 2-nitrobenzoate (abbreviated as LH2NB (I); ([C6H10N3O2]+[C7H4NO4]−)), was synthesized. The molecular structure of LH2NB (I) was elucidated using single crystal X-ray diffraction technique.
