Microcirculatory changes during chronic adaptation to hypoxia.
Microcirculatory changes in the window chamber preparation in Syrian golden hamsters, secondary to chronic hypoxia adaptation, are presented herein. Adaptation was attained by keeping animals in a 10% oxygen environment for 1 wk and 5% the following week. The following groups were studied: group 1, adapted to chronic hypoxia and kept in a 5% oxygen environment throughout the experiment; group 2...
متن کاملHypoxia-Induced Adaptation to Mitral Regurgitation
Mitral regurgitation (MR) is a common cardiac problem that increases dramatically with age. The consequences of MR are left ventricular volume overload, cardiac hypertrophy, and the eventual development of left ventricular dilation and dysfunction. Compensated or decompensated MR can result in a number of molecular changes in the myocardium that may be either adaptive or maladaptive. Tissue hyp...
متن کاملDevelopmental adaptation to high altitude hypoxia.
Experimental studies on animals and humans exposed to hypoxic stress have been reviewed. These data suggest that the influence of hypoxic stress, and the organism's response to it, are greater during growth than during adulthood. The organism's responses include alterations in the quantity and size of the alveolar units of the lungs, enlargement of the right ventricle of the heart, slower somat...
متن کاملChimera or not chimera?
The article entitled " Evidence for Cardiomyocyte Repopulation by Extracardiac Progenitors in Transplanted Human Hearts " by Laflamme et al, 1 published in Circulation Research, confirms our early observations 2 that cardiac chimerism occurs after transplanta-tion of a female heart in a male patient. These results are also in agreement with the detection of chimerism in multiple organs after bo...
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...
