Single copy/knock-in models of ALS SOD1 in C. elegans suggest loss and gain of function have different contributions to cholinergic and glutamatergic neurodegeneration [PDF]
Mutations in Cu/Zn superoxide dismutase 1 (SOD1) lead to Amyotrophic Lateral Sclerosis (ALS), a neurodegenerative disease that disproportionately affects glutamatergic and cholinergic motor neurons.

A carbon nanotube‐based biopesticide system (BioCNTs) enables efficient delivery and systemic movement of RNAi molecules to control major tomato viruses. By integrating shRNA and tRNA‐like structures (TLS) with BioCNTs, this green and scalable approach achieves long‐term silencing and high antiviral efficacy through simple foliar spraying.

Superoxide dismutase in leukocytes [PDF]
1 ] or NBT [ 141 in the xanthine-xanthine oxidase reaction. The reduction of NBT and cytochrome c was followed at 560 and 550 nm respectively. One unit of SOD activity is defined as the amount of enzyme that causes a decrease of the optical density from 0.025 to 0.0125 in 1 min using 1 cm light path cuvette.

Particulate matter ≤2.5 µm (PM2.5) elevates risks of neurological and chronic metabolic diseases, but the underlying mechanisms linking PM2.5‐induced central nervous system (CNS) injury to metabolic dysfunction remain unclear. Hypothalamic pro‐opiomelanocortin‐expressing (POMC+) neurons regulate systemic metabolic homeostasis, and tripartite motif ...

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

Familial ALS-superoxide dismutases associate with mitochondria and shift their redox potentials [PDF]
Recent studies suggest that the toxicity of familial amyotrophic lateral sclerosis mutant Cu, Zn superoxide dismutase (SOD1) arises from its selective recruitment to mitochondria. Here we demonstrate that each of 12 different familial ALS-mutant SOD1s

Mouse models for preeclampsia: disruption of redox-regulated signaling [PDF]
The concept that oxidative stress contributes to the development of human preeclampsia has never been tested in genetically-defined animal models. Homozygous deletion of catechol-Omethyl transferase (Comt-/-) in pregnant mice leads to human preeclampsia ...
