Effect of summer welfare management on serum biochemical indexes, antioxidant function and relative gene expression levels of donkey foals

open access: yesSiliao yanjiu, 2022
The experiment was to investigate the effect of spraying and fanning on donkey foals' serum biochemical indexes, antioxidant function and relative gene expression levels in summer, to provide reference for welfare management of donkey foals in summer. 24

Antioxidant function of melanin in black fungi [PDF]

open access: yesInfection and Immunity, 1995
1,8-Dihydroxynaphthalene melanin in Wangiella dermatitidis and Alternaria alternata was titrated in vivo with the oxidants permanganate, hypochlorite, and H2O2. Melanized strains neutralized more oxidant and withstood higher concentrations of permanganate and hypochlorite than albino strains did.

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death

open access: yesFEBS Open Bio, EarlyView.
Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Effects of retinoic acid on the synthesis of selenoprotein and the antioxidative indices of bovine mammary epithelial cells in vitro

open access: yesCzech Journal of Animal Science, 2016
The present study was conducted to examine the effects of retinoic acid (RA) on the synthesis of selenoprotein and the antioxidative indices of bovine mammary epithelial cells (BMEC) in vitro and to explore the antioxidative mechanisms of RA in the BMEC.

Cyclic azapeptide CD36 ligand attenuates cardiac injury and reduces long‐chain fatty acid accumulation after myocardial ischemia–reperfusion in mice

open access: yesFEBS Open Bio, EarlyView.
In a murine model of myocardial ischemia and reperfusion (MI/R), the CD36 azapeptide ligand MPE‐298 reduces cardiac injury and transiently lowers left ventricular long‐chain fatty acids (LCFAs) accumulation 3 h after reperfusion, accompanied by a decrease of oxidative stress and inflammation‐associated genes' expression in the heart and adipose tissue.

The antioxidant function of sestrins is mediated by promotion of autophagic degradation of Keap1 and Nrf2 activation and by inhibition of mTORC1.

open access: yesFree Radical Biology & Medicine, 2015
Sestrins 1 to 3 constitute a family of proteins that are induced in mammalian cells in response to environmental stressors. Despite their apparent lack of intrinsic catalytic antioxidant activity, Sestrins protect cells from oxidative stress by lowering ...

UiO‐66 metal–organic frameworks in biomedicine: From structural tunability to bioimaging, photodiagnostics, and photodynamic cancer therapy

open access: yesFEBS Open Bio, EarlyView.
UiO‐66(Zr) metal–organic frameworks are chemically stable, biocompatible, and highly tunable nanomaterials. Their modular structure enables controlled drug delivery, multimodal bioimaging, and light‐activated photodynamic therapy, supporting integrated diagnostic and therapeutic (theranostic) applications in cancer and biomedical research.

Effects of different sources of selenium in broiler breeder diet on selenium deposition, antioxidant indices and growth performance of offspring broiler

open access: yes浙江大学学报. 农业与生命科学版, 2010
A total of 240 39-week-old Lingnan Yellow broiler breeders were randomly allocated to two groups, which were fed with the basal diet containing 0.04 mg·kg-1 Se with the supplement of 0.30 mg Se·kg-1 sodium selenite (SS) and DL-selenomethionine (SM ...

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

open access: yesFEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...
