As a physiologist interested in contemplative practice and meditation I have enjoyed the opportunity of lecturing to students engaged in the study of contemplation. My pedagogic role was to expose them to some of what we know of the biological phenom

Background — Previously, we have observed that the isolated, erythrocyte-perfused rabbit heart has increased levels of heat-shock protein (HSP) 72 after a mild mechanical stress. We hypothesized that stretch-activated ion channels (SACs) mediated t

Background: The mechanisms that mediate fetal brain injury which results from maternal alcohol consumption are not well understood. Although fetal hypoxia is a popularly proposed mechanism, it has been difficult to assess brain oxygenation in vivo. W

Heat shock proteins (HSPs) may play a cardioprotective role during hypoxia or ischemia. We hypothesized that cardiac tissue from hypoxia-tolerant animals might have high levels of specific HSPs. We measured myocardial HSP60 and HSP72/73 in painted an

As part of our ongoing research on cardiac hypoxia tolerance we have conducted 31P nuclear magnetic resonance (NMR) studies of isolated, perfused, working hearts from freshwater turtles, animals that are well known for their ability to tolerate prolo

One of the most important negative consequences of hypoxic stress in the mammalian myocardium is a breakdown in intracellular calcium homeostasis. This study examines the effects of anoxic stress on intracellular calcium regulation in isolated ventri

Nuclear magnetic resonance (NMR) spectroscopy, a technique originally developed by physicists and used for many years by chemists, has more recently become a powerful tool for the noninvasive and nondestructive study of intracellular biochemistry. Co

Selected tissues (skeletal muscle, heart ventrical, and liver), sampled from turtles (Chrysemys picta bellii) at 3°C either under normoxic conditions or after 12 weeks of anoxic submergence were quantiaatively analysed for intracellular pH and phosp

We compared extracellular and intracellular acid-base states in paralyzed bullfrogs subjected to 4 h of anoxic submergence at 15°C with or without maintenance of extracellular pH at preanoxic levels by bicarbonate infusion. We also assessed anaerobi
