Recent Perspectives on Phytochemical Profile, Pharmacological Activities, and Industrial Applications of Guava (Psidium guajava)

open access: yesFood Safety and Health, EarlyView.
Psidium guajava leaves contain potent bioactive compounds like quercetin, myricetin, and triterpenoids that show antioxidant, antidiabetic, anti‐inflammatory, and anticancer effects. They act by modulating NF‐κB, PPARγ, and α‐glucosidase and by inducing apoptosis and cell cycle arrest.

キイロショウジョウバエ由来のチオレドキシン還元酵素のC未端テトラペプチド配列は、ヒト肺由来のチオレドキシン還元酵素では酸化還元活性を示さない [PDF]

open access: yes, 2007
The isozymes of mammalian thioredoxin reductase (TrxR) contain the penultimate selenocysteineresidue (SeCys) in the redox-active C-terminal tetrapeptide, -Gly-Cys-SeCys-Gly (end). Amutant form of the mammalian enzyme TrxR-X498C in which SeCys is replaced

Protective Effects of Fenugreek and Stevia Extracts on Dexamethasone‐Induced Testicular Damage in a Rat Model

open access: yesFood Safety and Health, EarlyView.
Fenugreek and stevia extracts protect against dexamethasone‐induced testicular damage in male rats by enhancing antioxidant defenses, improving sperm quality, and restoring hormonal balance, highlighting their potential as natural therapeutics for preventing corticosteroid‐induced reproductive toxicity.

Pharmacological effects of gastrodin: Insight into neurological diseases and mechanism in ferroptosis and pyroptosis

open access: yesIbrain, Volume 11, Issue 1, Page 74-83, Spring 2025.
Pharmacological effects of gastrodin include prevention and treatment of cognitive decline and reperfusion injuries, anticonvulsion, antiepilepsy, antidepressants, and analgesia, which are related to antiferroptosis and antipyroptosis. Abstract Gastrodin, as an effective monomer of gastrodia elata, plays a significant role in anti‐inflammatory ...

SUMOylation regulates tumorigenesis and progression: Molecular mechanisms and therapeutic applications

open access: yesInterdisciplinary Medicine, EarlyView.
SUMOylation, a dynamic post‐translational modification, acts as a master regulator at the heart of tumor malignancy. Our work delineates how the SUMOylation cycle—mediated by E1/E2/E3 enzymes and reversed by SENPs—orchestrates multiple hallmarks of cancer. The central pathway converges on three critical pathological axes: 1.

Subchronic Exposure to Arsenic and Nickel Triggers Nitrosative Stress and Histological Alterations in the Rat Liver

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Environmental exposure to heavy metals poses a threat to human health. Several studies documented harmful effects on the liver after arsenic and nickel exposure at concentrations beyond permissible limits. Nevertheless, the impact of a simultaneous exposure to both elements on hepatic biochemistry and histology remains unelucidated. Therefore,

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

open access: yesJournal 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 ...
