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 ...

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]‐

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

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.

Systemic Consequences of Chronic Ethanol Intake: From Microbiome Shifts to Metabolic Impairment

Comprehensive Physiology, Volume 16, Issue 2, April 2026.
Chronic ethanol intake disrupts whole‐body homeostasis by reducing energy intake and body mass, impairing physical function, and reshaping the gut microbiome. Microbiota shifts and depletion of short‐chain fatty acids increase gut permeability and drive hepatic inflammation, dyslipidemia, and glucose intolerance.

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).

The Oldest Traces of Alcoholic Beverages in the Border Zone of the North and East European Plains

Archaeometry, Volume 68, Issue 2, Page 153-172, April 2026.
ABSTRACT Analysis of organic compounds preserved on pottery from the Bell Beaker community and the initial phase of the Trzciniec Cultural Sphere in the border zone of the Eastern and North European Plains was prompted by traces of alcoholic beverages found in contextually and formally analogous discoveries of more westerly provenance.

Enantioselective Determination of Chiral Fungicides in Food Samples Using Automated Dispersive Microextraction Coupled With UHPLC–MS/MS

Food Frontiers, Volume 7, Issue 2, March 2026.
The use of fatty acids and bio‐derived solvents eliminates the need for toxic solvents and, when combined with automated workstations, enables parallel sample processing, thereby improving extraction efficiency and reducing human error. ABSTRACT An enantioselective analytical method based on automated dispersive liquid–liquid microextraction (DLLME ...
