Corticosterone and Mitochondrial Efficiency Are Associated With Changes in DNA Oxidative Damage During an Acute Stress Response in Leach's Storm‐Petrels (Hydrobates leucorhous)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

8-Hydroxy-2’-deoxyguanosine level and antioxidant status in the dynamics of physiological pregnancy

Acta Biomedica Scientifica
Background. Due to the adaptive processes occurring in a woman’s body during pregnancy, the antioxidant status may be the subject for active changes. An imbalance between antioxidants and prooxidants may lead to the development of oxidative stress.

Bridging Psychological Stress and Skin Cellular Aging: Flavonoids as a Dual‐Action Therapeutic Strategy

Phytotherapy Research, EarlyView.
ABSTRACT Psychological stress (or simply “stress”) is a major contributor to chronic disease worldwide, affecting 35% of the global population, including younger generations. Furthermore, it plays a significant role in human premature aging; hence, its detrimental effects on people's health compel us to comprehend and control the ways in which ...

Nuclear 8-hydroxy-2'-deoxyguanosine as survival biomarker in patients with cutaneous melanoma

Oncology Reports, 2009
8-hydroxy-2'-deoxyguanosine (8-OHdG) is one of the main mutagenic modifications induced in DNA by oxidative stress. Elevated levels of 8-OHdG have been regarded as an independent prognostic factor in different types of cancer. Various enzymes, such as human 8-oxoguanine DNA-glycosylase 1 (hOGG1) and glucose-6-phosphate dehydrogenase (G6PD), act as ...
