Cerebrospinal fluid metabolomics reveals altered waste clearance and accelerated aging in HIV patients with neurocognitive impairment [PDF]

, 2014
Objective(s): HIV-associated neurocognitive disorders (HAND) remain prevalent in HIV-infected patients on antiretroviral therapy (ART), but the underlying mechanisms are unclear. Some features of HAND resemble those of age-associated cognitive decline in

Smart, Bio‐Inspired Polymers and Bio‐Based Molecules Modified by Zwitterionic Motifs to Design Next‐Generation Materials for Medical Applications

Advanced Functional Materials, Volume 36, Issue 40, 18 May 2026.
Bio‐based and (semi‐)synthetic zwitterion‐modified novel materials and fully synthetic next‐generation alternatives show the importance of material design for different biomedical applications. The zwitterionic character affects the physiochemical behavior of the material and deepens the understanding of chemical interaction mechanisms within the ...

The Structural Basis of Coenzyme A Recycling in a Bacterial Organelle. [PDF]

, 2016
Bacterial Microcompartments (BMCs) are proteinaceous organelles that encapsulate critical segments of autotrophic and heterotrophic metabolic pathways; they are functionally diverse and are found across 23 different phyla. The majority of catabolic BMCs (

The Role of the B12 Coenzyme in the Conversion of 1,2-Propanediol to Propionaldehyde

Journal of Biological Chemistry, 1966
Abstract When 1,2-propanediol-1-3H is converted to propionaldehyde in the presence of dioldehydrase and 5,6-dimethylbenzimidazolylcobamide 5'-deoxyadenosine, 2 hydrogen atoms per mole of the coenzyme are replaced by tritium. The tritiated coenzyme so obtained transfers tritium to the product when it is added to unlabeled 1,2-propanediol and ...

Catalytic Transfer Hydrogenation Reactions of Glycerol Over Zr‐Incorporated Zeolite Beta Prepared by a Mechanochemical Approach

ChemCatChem, Volume 18, Issue 9, 14 May 2026.
Metal‐modified beta zeolite has long been recognized as an important catalyst for reactions involving acid and bifunctional catalysis. The gas‐phase conversion of glycerol over Zr‐beta (prepared by a mechanochemical approach) demonstrated the remarkable versatility of this catalytic system, evidenced by the production of glycerol hydrogenolysis ...

A Probiotic Combination of Limosilactobacillus reuteri and Clostridium butyricum Ameliorates 5‐Fluorouracil‐Induced Intestinal Mucositis in Rats by Strengthening Barrier Integrity and Modulating Immuno‐Microbial Homeostasis

Journal of Cellular Physiology, Volume 241, Issue 5, May 2026.
A probiotic formulation of Limosilactobacillus reuteri and Clostridium butyricum provides prophylactic protection against 5FU‐induced mucositis by strengthening the intestinal barrier, reshaping the microbiota to reduce pathogenic load, and regulating immune‐inflammatory response via TLR4‐mediated pathway.

1,2-propanediol metabolism by heterofermentative lactobacilli in sourdough

International Journal of Food Microbiology
The conversion of lactate to 1,2-propanediol and 1,2-propanediol to propionate sustains viability and metabolic activity of stationaryphase cells of lactobacilli over weeks or even months. The pathway was described only in few lactobacilli, and factors regulating its expression remain poorly understood. This study investigated the metabolic pathways of

Mucin Type Drives Composition and Mucin Glycan Degradation of an In Vitro Synthetic Microbial Community

Environmental Microbiology, Volume 28, Issue 5, May 2026.
The human gut outer mucus layer hosts specific microbes. Using a synthetic mucin glycan‐degrading microbial community to mimic this mucosal microbiome, we show that mucin type affects microbial community composition, glycan degradation and metabolite production.
