Oxidative Stress in Pregnancy

open access: yesBiomolecules, 2023
Recent years have seen an increased interest in the role of oxidative stress (OS) in pregnancy. Pregnancy inherently heightens susceptibility to OS, a condition fueled by a systemic inflam-matory response which culminates in an elevated presence of reactive oxygen species (ROS) and reactive nitrogen species (RNS) in the circulatory system.

Antioxidants, Food Processing and Health

open access: yesAntioxidants, 2021
The loss and/or modification of natural antioxidants during various food processing techniques and storage methods, like heat/thermal, UV, pulsed electric field treatment, drying, blanching and irradiation is well described. Antioxidants in their reduced

Internal Interface Strains Effects on UO2/U3O7 Oxidation Behaviour [PDF]

open access: yesDefect and diffusion forum 297-301 (2010) 519-524, 2010
The growth of a U3O7 oxide layer during the anionic oxidation of UO2 pellets induced very important mechanical stresses due to the crystallographic lattice parameters differences between UO2 and its oxide. These stresses, combined with the chemical processes of oxidation, can lead to the cracking of the system, called chemical fragmentation.

A stress-blinded Atf1 can fully assemble heterochromatin in a RNAi-independent minimal mat locus but impairs directionality of mat2/3 switching

open access: yesiScience, 2022
Summary: The MAP kinase Sty1 phosphorylates and activates the transcription factor Atf1 in response to several stress conditions, which then shifts from a transcriptional repressor to an activator.

Oxidative Stress in Aging [PDF]

open access: yesOxidative Medicine and Cellular Longevity, 2014
Constant formation of free radicals mainly reactive oxygen species (ROS) is the main characteristic of all living systems which use oxygen for their basal metabolism. Primarily, ROS are considered an integral component of basic cell regulation and signaling pathways certainly, suppressing tumor progression which forms the basis of the most ...

Effects of an Exercise Test on Inflammation and Oxidative Stress Biomarkers in Patients with Metabolic Syndrome

open access: yesProceedings, 2019
Metabolic syndrome is characterized by an increase in oxidative stress and chroniclow-grade inflammation. The effects of an exercise test at 60–70% of the maximum capacity wasevaluated on inflammatory and antioxidant response in elderly people ...

Shot-Peening of Pre-Oxidized Plates of Zirconium: Influence of Residual Stress on Oxidation [PDF]

open access: yes, 2013
The present study deals with oxidation behavior under residual stress of shot-peened plates of "commercially pure" zirconium exposed for 30 min at 650 C. The influence of the shot-peening on a pre-oxidized material is presented. The results have been used to determine the influences of these chemical (preoxidation) and mechanical (shot-peening ...

OXIDATIVE STRESS AND ENDOMETRIOSIS [PDF]

open access: yesEpidemiology, 2004
Little is known about the aetiology of endometriosis; however, in the presence of oxidative stress, reactive oxygen species might increase growth and adhesion of endometrial cells in the peritoneal cavity, leading to endometriosis and infertility. Within a study investigating persistent organic compounds and endometriosis, the authors evaluated the ...
