Role of oxidative stress in atherosclerosis

The American Journal of Cardiology, 2003
The common risk factors for atherosclerosis increase production of reactive oxygen species (ROS) by endothelial, vascular smooth muscle, and adventitial cells. These ROS initiate processes involved in atherogenesis through several important enzyme systems, including xanthine oxidase, nicotinamide adenine dinucleotide phosphate (NADPH) oxidases, and ...

Roles of TRPM2 in oxidative stress

Cell Calcium, 2011
Reactive oxygen species (ROS) play critical roles in cell death, diseases, and normal cellular processes. TRPM2 is a member of transient receptor potential (TRP) protein superfamily and forms a Ca(2+)-permeable nonselective cation channel activated by ROS, specifically by hydrogen peroxide (H(2)O(2)), and at least in part via second-messenger ...

The role of deep breathing on stress

Neurological Sciences, 2016
The objective of this study was to verify, in a sample of university students, whether a relaxing technique called deep breathing (stress Intervention Functional IFA) is capable to improve the mood and to reduce the levels of stress. Thirty-eight adult healthy subjects (aged between 18 and 28 years) volunteered the study.

The role of the pineal gland in stress

Journal of Neural Transmission, 1980
A short survey of the results of our previous research into the protective role of the pineal gland against stress is given. The neuroendocrine aspect of a chronic auditory stress and the neuroendocrine aspect of ulcer disease in man were studied. Auditory stress: hypertrophy and hyperplasia of pinealocytes, hyperplasia of the STH, FSH, LTH and TSH ...
