Vasomotor responses to hypoxia in type 2 diabetes.
Type 2 diabetes is associated with vascular dysfunction, accelerated atherosclerotic morbidity, and mortality. Abnormal vasomotor responses to chemoreflex activation may contribute to the acceleration of atherosclerotic diabetes complications, but these responses have not previously been investigated. We measured forearm mean blood flow (MBF) and mean vascular conductance (MVC) responses to iso...
متن کاملCross-Adaptation: Heat and Cold Adaptation to Improve Physiological and Cellular Responses to Hypoxia
To prepare for extremes of heat, cold or low partial pressures of oxygen (O2), humans can undertake a period of acclimation or acclimatization to induce environment-specific adaptations, e.g. heat acclimation (HA), cold acclimation (CA), or altitude training. While these strategies are effective, they are not always feasible due to logistical impracticalities. Cross-adaptation is a term used to...
متن کاملHypoxia and fungal pathogenesis: to air or not to air?
Over the last 3 decades, the frequency of life-threatening human fungal infections has increased as advances in medical therapies, solid-organ and hematopoietic stem cell transplantations, an increasing geriatric population, and HIV infections have resulted in significant rises in susceptible patient populations. Although significant advances have been made in understanding how fungi cause dise...
متن کاملAdaptational responses to hypoxia.
WITH THE EVOLUTIONARY TRANSITION of life from water to land, adaptation of the organism to changing environmental conditions became critical for survival. One of the most dramatic life-threatening situations is a reduction in oxygen supply to the vital organs. Decreased tissue oxygenation may arise on such different occasions as exposure to low ambient oxygen, i.e., at high altitude, or during ...
متن کاملGlycerol hyperhydration: physiological responses during cold-air exposure.
Hypohydration occurs during cold-air exposure (CAE) through combined effects of reduced fluid intake and increased fluid losses. Because hypohydration is associated with reduced physical performance, strategies for maintaining hydration during CAE are important. Glycerol ingestion (GI) can induce hyperhydration in hot and temperate environments, resulting in greater fluid retention compared wit...
