Oxidative stress in honey bees (Apis mellifera) and small carpenter bees (Ceratina calcarata) across different landscapes

Physiological Entomology, EarlyView.
First comparative study in oxidative stress between wild bees and managed bees. Bees collected from organic landscapes exhibited the lowest OX levels. Pesticide profiles were different among landscapes. Abstract Oxidative stress (OX) is a state of imbalance between antioxidants and reactive oxygen species, which are the byproducts of oxidative ...

Cross-sectional and longitudinal study of association between circulating thiobarbituric acid-reacting substance levels and clinicobiochemical parameters in 1,178 middle-aged Japanese men - the Amagasaki Visceral Fat Study

Nutrition & Metabolism, 2011
Background Circulating thiobarbituric acid-reacting substance (TBARS) levels, a marker of systemic oxidative stress, are predictive of cardiovascular events.

Foeniculum vulgare Essential Oils: Chemical Composition, Antioxidant and Antimicrobial Activities [PDF]

, 2010
The essential oils from Foeniculum vulgare commercial aerial parts and fruits were isolated by hydrodistillation, with different distillation times (30 min, I h, 2 h and 3 h), and analyzed by GC and GC-MS. The antioxidant ability was estimated using four

Cardiovascular autonomic dysfunction and oxidative stress induced by fructose overload in an experimental model of hypertension and menopause [PDF]

, 2014
Background: Metabolic syndrome is characterized by the association of 3 or more risk factors, including: abdominal obesity associated with an excess of abdominal fat, insulin resistance, type 2 diabetes, dyslipidemia and hypertension.

Probing the Tevatron t tbar asymmetry at LHC

, 2011
We use an effective operator framework to study the contributions to the Tevatron t tbar asymmetry from arbitrary vector bosons and scalars, and compare with their effect on the t tbar tail at LHC. Our study shows, for example, that models reproducing the t tbar asymmetry by exchange of Z' and W' bosons or colour-triplet scalars lead to a large ...

Optimal timing to assess exercise‐induced oxidative stress: A systematic review and meta‐analysis

Experimental Physiology, EarlyView.
Abstract There is a lack of consensus on optimal timing to assess redox biomarkers post‐exercise, limiting methodological standardisation and linking oxidative stress to physiology. We determined optimal post‐exercise oxidative stress assessment times using three redox biomarkers: glutathione, F2‐isoprostanes and protein carbonyls.

Physiological Effects of Five Different Marine Natural Organic Matters (NOMs) and Three Different Metals (Cu, Pb, Zn) on Early Life Stages of the Blue Mussel (Mytilus galloprovincialis) [PDF]

, 2017
Metals are present in aquatic environments as a result of natural and anthropogenic inputs, and may induce toxicity to organisms. One of the main factors that influence this toxicity in fresh water is natural organic matter (NOM) but all NOMs are not the

Time‐ and cultivar‐dependent biochemical responses to heat priming and stress in rice

Annals of Applied Biology, Volume 189, Issue 1, July 2026.
Global warming increasingly threatens rice productivity, and understanding the biochemical mechanisms underlying heat stress responses is crucial for developing resilient cultivars. By demonstrating that stress responses are both cultivar‐ and time‐of‐day‐dependent, our findings offer new insights into the temporal and genetic regulation of acquired ...

Melatonin and Quercetin Co‐Treatment Attenuates Hepatic Damage in Diabetic Rats by Mitigating Oxidative Stress and Inflammation [PDF]

J Biochem Mol Toxicol
Quercetin and melatonin, alone or combined, effectively protect the liver in diabetic rats. The antioxidants reduce hyperglycemia, oxidative stress, and inflammation, preventing hepatic damage. ABSTRACT Liver complications in diabetes are very common, contributing to a high mortality rate, making it essential to develop strategies to minimize this ...
