Flavin nucleotides in human lens: Regional distribution in Brunescent cataracts

Indian Journal of Ophthalmology, 1998
The biochemical mechanism(s) underlying brunescent cataracts remain unclear. Oxidative stress due to reactive oxygen species may have a role in the pigmentation process in eye lens.

Versatile roles of protein flavinylation in bacterial extracyotosolic electron transfer

mSystems
Bacteria perform diverse redox chemistries in the periplasm, cell wall, and extracellular space. Electron transfer for these extracytosolic activities is frequently mediated by proteins with covalently bound flavins, which are attached through post ...

Binuclear Copper‐Dependent Oxidative Enzymes Involved in Fungal Natural Product Modifications

Journal of the Chinese Chemical Society, EarlyView.
This article summarizes recent biochemical characterizations of a new enzyme family named by the authors as binuclear copper‐dependent oxidative enzymes (BiNCOs). Found in fungal natural product biosynthesis, BiNCOs catalyze diverse CH functionalization reactions, including C(sp3)H halogenation, C(sp3)H hydroxylation, C(sp3)O macrocyclization, and ...

A Comprehensive Study of Bidirectional Interactions Between the Human Microbiome and Blood Malignancies and Hematologic Conditions: Focus on Novel Therapeutic Strategies

Journal of Clinical Laboratory Analysis, EarlyView.
Microbiota‐targeted therapeutic strategies in hematological disorders. aHSCT: Transplanted immune cells from the donor may attack the recipient's tissues, especially when damage to the intestinal epithelium disrupts the gut microbiota, contributing to GVHD. Maintaining a balanced gut microbiota that supports immune regulation helps reduce GVHD risk and

Babysitting Flavin for Biosynthesis

Chemistry & Biology, 2012
Enzymes involved in natural product biosynthesis employ a variety of cofactors, reaction mechanisms, and substrate preferences to achieve remarkable chemical diversity found in nature. In this issue of Chemistry & Biology, Goldman and colleagues show how cofactor (FAD) binding affinity impacts the reaction mechanism and outcome of two related proteins,

From regulatory mechanisms to cutting‐edge applications: Research progress of ultrasound, electrical, magnetic, and optical stimulation in neural modulation

Journal of Intelligent Medicine, EarlyView.
Abstract In recent years, the clinical treatment and symptom management of neurological disorders have faced significant challenges due to the high complexity of the nervous system's structure and function. Against this backdrop, physical stimulation techniques have emerged as a vital complementary approach to traditional pharmacological treatments and

A multicenter, controlled, randomized trial of home‐applied dual‐light photodynamic therapy in stage I to III periodontitis (LumoNorth2022 study)

Journal of Periodontology, EarlyView.
Abstract Background Periodontitis is a widespread, chronic infection‐triggered inflammatory condition in which professional supportive periodontal care (SPC) and daily oral hygiene form the backbone to reduce the disease activity. Light‐based treatments have shown promising antibacterial effects, but their potential for routine home use has not been ...

A study on the NAD(P)+ transhydrogenase from Azotobacter vinelandii [PDF]

, 1975
Azotobacter vinelandii transhydrogenase shows a pronounced polymerizing depolymerizing character (Chapter 3 and 5). Several factors seem to influence this phenomenon.

Effects of catechins, resveratrol, silymarin components and some of their conjugates on xanthine oxidase‐catalyzed xanthine and 6‐mercaptopurine oxidation

Journal of the Science of Food and Agriculture, Volume 105, Issue 5, Page 2765-2776, 30 March 2025.
Abstract BACKGROUND Over the past two decades, the global incidence of gout has markedly increased, affecting people worldwide. Considering the side effects of xanthine oxidase (XO) inhibitor drugs (e.g. allopurinol and febuxostat) used in the treatment of hyperuricemia and gout, the potential application of phytochemicals has been widely studied.
