Linoleic Hydroperoxides Are Potent Hyperoxidative Agents of Sensitive and Robust Typical 2-Cys Peroxiredoxins

Antioxidants
Typical 2-Cys peroxiredoxins (2-Cys Prxs, AhpC/Prx1 subfamily) are ubiquitous thiol peroxidases that efficiently reduce H2O2 and other hydroperoxides via a reactive peroxidatic Cys (CP).

TGA/FTIR Studies on the Thermal Degradation of some Polymeric Sulfonic and Phosphonic Acids and Their Sodium Salts [PDF]

, 1999
The thermal degradation of poly(vinyl sulfonic acid) and its sodium salt, poly(4-styrenesulfonic acid) and its sodium salt, and poly(vinylphosphonic acid) was studied by a combination of techniques, including TGA/FTIR, to identify the volatile products ...

A critical role of heterotrophic bacteria in early diagenesis of carbonates through exopolymer degradation and calcium release

The Depositional Record, Volume 12, Issue 1, February 2026.
Exopolymeric substances (EPS) produced in the photic zone and surface sediments sequester calcium. Below the sediment surface, heterotrophic bacteria degrade EPS, releasing calcium resulting in carbonate precipitation. This process, which continues for millennia deep in the core, is an important sink for atmospheric carbon dioxide.

A Cobalt-Containing Eukaryotic Nitrile Hydratase [PDF]

, 2017
Nitrile hydratase (NHase), an industrially important enzyme that catalyzes the hydration of nitriles to their corresponding amides, has only been characterized from prokaryotic microbes. The putative NHase from the eukaryotic unicellular choanoflagellate

Oxidative Stress: Molecular Mechanisms, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 2, February 2026.
Oxidative stress occurs when the reactive oxygen species (ROS) production overwhelms the ROS scavenging, which lead to genomic instability, epigenetic regulation, proteostasis imbalance, and lipid peroxidation, subsequently causing the occurrence and development of numerous diseases. ABSTRACT Although the physiological level of reactive oxygen species (

The ketogenic diet alters microbiome‐metabolome profiles to improve West syndrome therapy

Pediatric Investigation, Volume 10, Issue 1, Page 10-24, February 2026.
The ketogenic diet alleviates West syndrome by reshaping gut microbiota (increasing Bacteroides, Parabacteroides, and reducing Escherichia and Bifidobacterium), and modulating metabolites—including anticonvulsant lipids (e.g., capric acid), suppressed harmful lipids (e.g., 2‐methylbutyroylcarnitine), and amino acids and analogs (e.g., 3‐sulfinoalanine)—

Parameters Influencing the Plasma‐Mediated Inactivation of Microorganisms and Viruses in Wastewater

Plasma Processes and Polymers, Volume 23, Issue 2, February 2026.
Wastewater parameters, e.g., chemical oxygen demand (COD), influences the antimicrobial and antiviral efficacy of plasma. ABSTRACT Pathogenic microorganisms and viruses in water pose an environmental risk demanding for effective remediation tools like physical plasma. However, parameters influencing its efficiency are mostly descriptive.
