Determination of Some Antioxidan Enzyme Activities in Fresh and Dry Grapes (Vitis vinifera L.)

Van Tıp Dergisi, 2020
INTRODUCTION: Phenolic compounds in fruits and vegetables are very important in terms of eliminating free radicals. Most phenolic compounds are known to have antioxidant activity and can help protect cells against oxidative damage caused by free radicals.

Role of Toll-Like Receptors in the interplay between pathogen and damage associated molecular patterns [PDF]

arXiv, 2019
Various theoretical studies have been carried out to infer relevant protein-protein interactions among pathogens and their hosts. Such studies are generally based on preferential attachment of bacteria / virus to their human receptor homologs. We have analyzed 17 pathogenic species mainly belonging to bacterial and viral pathogenic classes, with the ...

Intercellular propagated misfolding of wild-type Cu/Zn superoxide dismutase occurs via exosome-dependent and -independent mechanisms

Proceedings of the National Academy of Sciences of the United States of America, 2014
Significance Amyotrophic lateral sclerosis (ALS), an incurable motor neuron disease, is associated with mutation and misfolding of the Cu/Zn superoxide dismutase (SOD1) protein.

Mechanical and Light Activation of Materials for Chemical Production

Advanced Materials, EarlyView.
The actuation of stomata—referring to their opening and closing—is crucial for photosynthesis because it regulates gas exchange and water balance. Here, it is investigated if this life‐like property could enhance the photocatalytic properties of soft materials.

3D Printing of Photocrosslinked Alginate Dialdehyde‐Gelatin Hydrogels Reinforced with Cobalt‐Containing Mesoporous Bioactive Glass Nanoparticles for Developing Skin Wound Dressings

Advanced Materials Interfaces, EarlyView.
Bioactive multi‐crosslinked hydrogels are prepared from gelatin methacrylate (GelMA), methacrylate‐functionalized alginate dialdehyde (ADAMA), and Cobalt‐doped mesoporous bioactive glass nanoparticles (Co‐MBGNs), demonstrating optimized elasticity, cytocompatibility, and wound healing potential.

Superoxide dismutase 1 acts as a nuclear transcription factor to regulate oxidative stress resistance

Nature Communications, 2014
Superoxide dismutase 1 (Sod1) has been known for nearly half a century for catalysis of superoxide to hydrogen peroxide. Here we report a new Sod1 function in oxidative signalling: in response to elevated endogenous and exogenous reactive oxygen species (

Progress and Application of Multifunctional Hydrogel in Radioactive Skin Injury

Advanced Materials Interfaces, EarlyView.
This review examines healing challenges in radiation‐wound injuries, where ionizing radiation impairs immune and tissue repair processes. Hydrogels, with their biocompatibility, antimicrobial properties, and drug delivery capabilities, present a transformative solution. It compares hydrogel efficacy in radiation‐induced versus common wounds, highlights

Time course of oxidative damage in different brain regions following transient cerebral ischemia in gerbils [PDF]

Neuroscience Research 41(3): 233-241 (2001), 2007
The time course of oxidative damage in different brain regions was investigated in the gerbil model of transient cerebral ischemia. Animals were subjected to both common carotid arteries occlusion for 5 min. After the end of ischemia and at different reperfusion times (2, 6, 12, 24, 48, 72, 96 h and 7 days), markers of lipid peroxidation, reduced and ...

SUPEROXIDE DISMUTASE IN BARLEY [PDF]

Journal of the Institute of Brewing, 1983
Superoxide dismutese occurs in barley where it can be measured using a xanthine oxidase assay, but not using an assay based on the reduction of Nitro Blue Tetrazolium by photo-reduced riboflavin. Three isozymes are present in the grain: two are cyanide-sensitive and one, of lower activity, is not.

ROS‐Driven Nanoventilator for MRSA‐Induced Acute Lung Injury Treatment via In Situ Oxygen Supply, Anti‐Inflammation and Immunomodulation

Advanced Science, EarlyView.
A ROS‐driven in situ oxygen supply nanoventilator based on enzyme nanocapsule can convert ROS into O2 through enzyme cascade reaction between SOD and CAT to relieve lung hypoxia, and kill MRSA by releasing vancomycin, which effectively reduces HIF‐1α expression and balances pro‐inflammatory/anti‐inflammatory macrophages ratio, thereby reducing the ...
