Results of recent trials highlight the risks of hormone therapy, increasing the importance of identifying preventive lifestyle factors related to menopausal symptoms. The authors examined the relation of such factors to vasomotor symptoms in the multiethnic sample of 3,302 women, aged 42-52 years at baseline (1995-1997), in the Study of Women's Health Across the Nation (SWAN). All lifestyle fac...

Although most women report vasomotor symptoms (hot flashes, night sweats) during midlife, their etiology and risk factors are incompletely understood. Body fat is positively associated with vasomotor symptoms cross-sectionally, but the longitudinal relation between changes in body fat and vasomotor symptoms is uncharacterized. The study aim was to examine whether gains in body fat were related ...

Introduction: Menopause is the most important event in middle-age. Women, in this period, face several changes. Vasomotor symptoms and skin changes are prevalent in the middle-age. This study, mainly, was performed identifying the vasomotor symptoms and skin changes in menopausal women. Materials and methods: Study sample was consisted of 150 women who have visited the healthcare centers, ...

BACKGROUND Central baroreflex failure in Shy-Drager syndrome and traumatic spinal cord injuries results in severe orthostatic hypotension and often confines the patient to the bed. We proposed a novel therapeutic strategy against central baroreflex failure: implementation of an artificial feedback control system able automatically to regulate sympathetic vasomotor tone, that is, a bionic barore...

Effects of Alpha Adrenergic Blockade on Autoregulation and Chemical Vasomotor Control of CBF in Stroke • Autoregulation and chemical vasomotor control of cerebral blood flow (CBF) were quantitatively tested in 19 patients with various types and sites of cerebral ischemia and infarction. The effect of alpha adrenergic blockade of cerebral vessels by phenoxybenzamine (PBZ) also was evaluated in m...

To evaluate the CO2-induced vasomotor reactivity of the cerebral vasculature, relative changes of blood flow velocity within the middle cerebral artery were measured by transcranial Doppler ultrasonography during normocapnia and various degrees of hypercapnia and hypocapnia. We studied 40 normal individuals and 40 patients with unilateral and 15 patients with bilateral internal carotid artery o...

The amount of tissue perfused, as determined from the difference in volume of distribution between a diffusible indicator (125I-antipyrine) and an intravascular indicator (131 I-albumin) was measured at different values of coronary flow, perfusion pressure, and vasomotor tone in the working left ventricle of an open-chest dog. Coronary pressure and flow were regulated independently from the sys...
