Serum short-chain fatty acids and its correlation with motor and non-motor symptoms in Parkinson’s disease patients

BMC Neurology, 2022
Background Parkinson’s disease (PD) is associated with enteric nervous system dysfunction and gut microbiota dysbiosis. Short-chain fatty acids (SCFAs), derived from gut microbiota, are supposed to anticipate PD pathogenesis via the pathway of spinal ...

Benzylammonium heptanoate–heptanoic acid (1/1)

Acta Crystallographica Section E, 2013
The title salt, C7H10N+·C7H13O2−·C7H14O2, is an unusual 2:1 stoichiometric combination of two carboxylic acid molecules and one amine. Although there are crystal structures of a number of 1:1 complexes reported in the literature, 2:1 acid amine complexes are rather uncommon.

Flowzonolysis: Continuous Oxidative Ozonolysis of Algae‐Derived Palmitoleic Acid for the Synthesis of Azelaic Acid

Chemistry–Methods, Volume 6, Issue 7, July 2026.
Flowzonolysis enables the continuous oxidative cleavage of algae‐derived palmitoleic acid to azelaic acid in a single integrated process. By combining alkene cleavage and oxidation without isolating reactive intermediates, this method minimizes auxiliary reagents, improves atom economy, and supports safer, more sustainable diacid production from ...

Structure–activity relationship study shows versatility in substrate specificity for heterodisulfide reductase in methanogenic archaea

Protein Science, Volume 35, Issue 7, July 2026.
Abstract Hydrogenotrophic methanogens are anaerobic archaea that convert carbon dioxide and hydrogen into methane. Central to this process is the heterodisulfide reductase (Hdr), which catalyzes the reduction of the heterodisulfide made of coenzyme M and coenzyme B. In vivo, Hdr functions in association with electron‐donating modules such as the [NiFe]‐

Evidence That Parietal Lobe Fatty Acids May Be More Profoundly Affected in Moderate Alzheimer’s Disease (AD) Pathology Than in Severe AD Pathology

Metabolites, 2018
Brain is a lipid-rich tissue, and fatty acids (FAs) play a crucial role in brain function, including neuronal cell growth and development. This study used GC-MS to survey all detectable FAs in the human parietal cortex (Brodmann area 7).

Constructing Asymmetric Cu–OV–Mn Sites on MOFs‐Derived Cu‐MnOx Microspheres With Abundant Oxygen Vacancies for Enhanced Photothermal VOC Degradation

Rare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT With the growing severity of volatile organic compounds (VOCs) pollution, metal‐organic frameworks (MOFs)‐derived materials offer a promising solution through efficient photothermal catalysis. In this paper, M‐MnOx (M = Cu, Ni, Co, Fe) catalysts derived from manganese‐based MOFs were successfully prepared by the sacrificial template method and
