Changes in expression of manganese superoxide dismutase, copper and zinc superoxide dismutase and catalase in Brachionus calyciflorus during the aging process. [PDF]

PLoS ONE, 2013
Rotifers are useful model organisms for aging research, owing to their small body size (0.1-1 mm), short lifespan (6-14 days) and the relative easy in which aging and senescence phenotypes can be measured.

Multifunctional Hydroxyapatite Coated with Gallium Liquid Metal‐Based Silver Nanoparticles for Infection Prevention and Bone Regeneration

Advanced Functional Materials, EarlyView.
A multifunctional hydroxyapatite (HAp) coating integrated with silver‐gallium liquid metal nanoparticles (HAp‐Ag‐GaNPs) exhibits dual antibacterial and osteogenic properties. It effectively inhibits Gram‐positive and Gram‐negative bacteria, including resistant strains, while enhancing bone regeneration.

Methylglyoxal interaction with superoxide dismutase 1

Redox Biology, 2020
Methylglyoxal (MG) is a highly reactive aldehyde spontaneously formed in human cells mainly as a by-product of glycolysis. Such endogenous metabolite reacts with proteins, nucleotides and lipids forming advanced glycation end-products (AGEs). MG binds to

Relationship between blood superoxide dismutase activity and zinc, copper, glutathione and metallothioneines concentrations in calves

Biomath, 2021
RedOx processes determine the resistance of the organism to pollutants. The aim of the study was to establish a possible relationship between copper and zinc concentration in the blood of calves and the enzyme activity of superoxide dismutase.

Evaluacion de un producto a base de aceite esencial de oregano sobre la integridad intestinal, la capacidad de absorcion de nutrientes y el comportamiento productivo de pollos de carne [PDF]

arXiv, 2022
Eight experiments were conducted to test an oregano-essential-oil-based product (PRO) on performance, gut health, and nutrient absorption capacity in broilers. The first three, up to 14d and without specific challenges, tested the effects on intestinal histology, skeletal integrity, and growth.

Cell Membrane Vesicle Camouflaged Artificial Cells

Advanced Functional Materials, EarlyView.
Artificial cells camouflaged with a cell membrane vesicle coating are able to assemble into synthetic aggregates that exhibit rudimentary communication capabilities. Additionally, when these artificial cells are equipped with antioxidant capabilities, they are able to protect the intracellular homeostasis in HepG2 cells present in semi‐synthetic ...

H2O2‐Generating Advanced Nanomaterials for Cancer Treatment

Advanced Functional Materials, EarlyView.
H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

Superoxide dismutase participation in plant adaptation to herbicides

Vìsnik Dnìpropetrovsʹkogo Unìversitetu: Serìâ Bìologìâ, Ekologìâ, 2005
Antioxidative enzyme superoxide dismutase (SOD) role in maize grain was investigated under herbicide action. Combinations of Dialen C with Harness, Primextra Gold and Frontier were used. Increasing in SOD activity proved to be a highly sensitive reaction.
