Preparation, Spectroscopic Elucidation, Antioxidant Potential, Enzyme Inhibition, and Molecular Docking Studies of Novel Schiff Base‐Derived Thiosemicarbazones

Chemistry &Biodiversity, Volume 23, Issue 11, November 2026.
The synthesis of new thiosemicarbazones bearing Schiff base was performed. The structures of the compounds were characterized through several spectroscopic methods. The antioxidant potential of these compounds was evaluated through DPPH• in vitro assays. In addition, their inhibitory activities against urease and xanthine oxidase (XO) were investigated.

Integrated Multi‐Omics Analysis of Human Cerebrospinal Fluid in Traumatic Spinal Cord Injury: An Exploratory Pilot Study

CNS Neuroscience &Therapeutics, Volume 32, Issue 11, November 2026.
Integrated proteomic and metabolomic profiling of human cerebrospinal fluid outlines a distinct molecular landscape of acute traumatic spinal cord injury. This exploratory analysis highlights a novel GOT2‐associated metabolic signature, involving concurrent decreases of GOT2, methionine, and 4‐acetamidobutanoic acid.

An RNA aptamer to the xanthine/guanine base with a distinctive mode of purine recognition

, 1998
RNAs that bind to xanthine (2,6-dioxypurine) were isolated from a population of 1012 random sequences by in vitro selection. These xanthine-binding RNAs were found to have a 10 nt consensus sequence at an internal loop in the most probable secondary ...

Alpinia oxyphylla Miq.: Chemical Constituents, Neuroprotective and Metabolic Effects, and Translational Challenges—A Review of Preclinical Evidence

Food Science &Nutrition, Volume 14, Issue 11, November 2026.
Alpinia oxyphylla Miq. (AOM), a medicinal and edible resource, contains diphenylheptanoids, polysaccharides, flavonoids, terpenoids, and phenolic acids. These constituents exert multi‐target synergistic effects by modulating neuroinflammation, oxidative stress, and the PI3K/Akt pathway, thereby improving Alzheimer's disease, Parkinson's disease, and ...

Prohibitive Effects of ω‐3 on Pancreatic Damage in an Experimental Diabetes Model: Blood Glucose, Insulin, Lipid Profiles, Oxidative Stress, Inflammation, Pancreatic Tissue Morphology, and Apoptotic Pathways

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 11, November 2026.
These omega 3 and duration doses have been studied for the first time in the literature. At this dose and duration, omega 3 has shown very strong antioxidant, anti‐inflammatory and apoptotic effects. Omega‐3 can be used to alleviate diabetes and diabetes‐related complications. ABSTRACT This study aimed to investigate the potential protective effects of

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, Volume 41, Issue 11, Page 1299-1310, November 2026.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.
