Roles of TRPM2 in oxidative stress
Cell Calcium, 2011Reactive 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 ...

On the Role of Shear Stress in Cardiogenesis
Endothelium, 2005The relative contribution of physical and chemical factors in organogenesis in general and in cardiogenesis in particular is an old and still unsolved question in developmental biology (Chang 1932, Anatomical Record, 51, 253-265). A recent Nature paper (Hove et al. 2003, Nature, 421, 172-177) strongly suggests (but does not prove) the important role of

Role of epinephrine in acute stress
Endocrinology and Metabolism Clinics of North America, 2002This article presents the likely pathway of stimuli generated by the recognition of high-intensity stressors to ultimately produce a fight-or-flight response. A key element is the recognition that psychological stressors that do not directly alter the internal environment represent the most important etiology of a fight-or-flight response ...

Role of Flavonoids in Oxidative Stress
Current Topics in Medicinal Chemistry, 2001Flavonoids are a group of naturally occuring compounds which are widely distributed in nature. Epidemiological evidence suggests an inverse relationship between dietary intake of flavonoids and cardiovascular risk. The biological activities of flavonoids are related to their antioxidative effects.

Personality Correlates of Role Stress
Psychological Reports, 1980The relationship between role stress, i.e., role ambiguity and role conflict, and personality as measured by Gough and Heilbrun's (1965) Adjective Check List was examined on the basis of data drawn from 202 nursing personnel. Experienced role ambiguity correlated .17 with defensiveness, .15 with self-control, .13 with endurance, —.13 with order, —.15 ...

The role of the pineal gland in stress
Journal of Neural Transmission, 1980A 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 ...
