Oxidant-Mediated Protein Amino Acid Conversion

open access: yesAntioxidants, 2019
Biological oxidation plays important roles in the pathogenesis of various diseases and aging. Carbonylation is one mode of protein oxidation. It has been reported that amino acids that are susceptible to carbonylation are arginine (Arg), proline (Pro ...

Nrf2-mediated neuroprotection response to recurrent hypoglycemia is insufficient to prevent cognitive impairment in a rodent model of type 1 diabetes [PDF]

open access: yes, 2016
It remains uncertain whether recurrent nonsevere hypoglycemia (Hypo) results in long-term cognitive impairment in type 1 diabetes (T1D). This study tested the hypothesis that specifically in the T1D state, Hypo leads to cognitive impairment via a ...

Organic and Inorganic Pollutants, Oxidative Stress Biomarkers, and Electrophoretic Protein Profiles in an Endangered Thresher Shark (Alopias vulpinus) From Southeastern Brazil: A Case Study

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT A comprehensive screening of different environmental contaminants (total metals, thermostable metal fractions associated with detoxification, and persistent organic pollutants) was conducted in an endangered common thresher shark (Alopias vulpinus ) individual incidentally captured in southeastern Brazil.

Plasma protein carbonylation in chronic uremia

open access: yesJournal of Nephrology, 2011
Carbonylation is an irreversible modification caused by the introduction into proteins of carbonyl derivatives (aldehydes and ketones), which can alter protein structure and function and lead to cellular dysfunction and tissue damage. Chronic uremia may be associated with an increased carbonyl overload ("carbonyl stress"), though carbonyl formation has

Quantitation of protein carbonylation by dot blot [PDF]

open access: yesAnalytical Biochemistry, 2012
Protein carbonylation is the most commonly used measure of oxidative modification of proteins. It is frequently measured spectrophotometrically or immunochemically by derivatizing proteins with the classical carbonyl reagent, 2,4-dinitrophenylhydrazine.

Gamete Formation Resets the Aging Clock in Yeast [PDF]

open access: yes, 2018
Gametogenesis is a process whereby a germ cell differentiates into haploid gametes. We found that, in budding yeast, replicatively aged cells remove age-induced cellular damage during gametogenesis.

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

Identification and evaluation of the role of the manganese efflux protein in [PDF]

open access: yes, 2010
Background Deinococcus radiodurans accumulates high levels of manganese ions, and this is believed to be correlated with the radiation resistance ability of this microorganism. However, the maintenance of manganese ion homeostasis in D.

A Lavandula angustifolia flower extract and dipeptide‐4 blend modulates oxidative, glycative, autophagic and circadian pathways in human skin models

open access: yesInternational Journal of Cosmetic Science, EarlyView.
The blend enhanced antioxidation, anti‐glycation, autophagy and circadian regulation in cell and skin models. Key markers included mitochondrial ROS, γ‐H2AX, AGEs, ATP, melatonin, LC3 and SOD. Significant improvements were visualized via fluorescence and quantified with statistical markers.

Endocrine‐Nutritional Synergy Between Sex Inversion and Microencapsulated Bioactives Enhances Growth, Intestinal Development, and Oxidative Stability in Nile Tilapia Larvae

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT This study evaluated the combined effects of sex inversion and microencapsulated supplementation with organic acids and essential oils on growth performance, tissue morphology, gene expression, and oxidative status in Nile tilapia (Oreochromis niloticus) larvae.
