Interactions of mild hypothermia and hypoxia on finger vasoreactivity to local cold stress

Acute cold stress and mild hypothermia impact on short-term, working memory and attention

Sports Research and Innovation Institute, Lithuanian Sports University, Sporto St. 6, LT-44221 Kaunas, Lithuania The effect of single acute cold water exposure on the cognitive function (short-term, working memory and attention) was examined in 25 male subjects who were exposed to 14 °C cold water (air temperature ~22 °C, rh ~45%) in the semi-recumbent posture (up to the shoulders) until the re...

Human Physiological Responses to Cold Stress and Hypothermia

Balancing hypoxia and hypothermia in cold-submerged frogs.

Many animals respond to hypoxic stress by selecting cooler environments, the so-called 'behavioural hypothermia' response. Amphibians overwintering in ice-covered ponds and lakes offer an ecologically relevant test of this response since they must choose between the confounding metabolic effects of profound hypothermia or hypoxia; thermal and chemical conditions can vary from 0 degrees C and no...

Effect of chronic local cold exposure on finger temperature responses.

17(2): 3’7-322. I g62.-Caucasian subjects from a temperate climate immersed their right index fingers in a stirred icewater bath for 20 min four times daily for I month. During subsequent test immersion, fingers exposed in this way showed an earlier initiation and a more rapid rate of spontaneous rewarming and a higher and more labile final temperature level than did either the same finger befo...

Improving Effects of Mild Cold Stress and Salicylic acid on Growth and Physiology of Periwinkle (Catharanthus roseus Don.)

To study effects of salicylic acid (SA) treatments (0, 0.5, 1 and 2 mM) in two forms of seed priming (for 24 h) and spraying on seedling at 4-6 leaf stage an experiment was conducted on periwinkle (Catharanthus roseus Don.) with and without exposure to a mild cold stress of 8 °C (for 32 h). Seeds were sown in trays containing peat-based substrate (with 20% sandy loam field soil). Transplants of...
