Cancer Cachexia: Metabolic Changes That Occur In Oxidative Capacity And Carbohydrate And Lipid Metabolism Of The Liver, Sarah Ramey
Health, Human Performance and Recreation Undergraduate Honors Theses
BACKGROUND: Cancer cachexia is defined as cancer-associated muscle wasting, and is a cancer side effect that dramatically affects cancer prognosis, is thought to be at least partially mediated by increased energy expenditure, and is directly responsible for the death of 20-40% of all cancer patients. Although the liver is known to be a predominant regulator of whole body metabolism, there is little known about its relationship to the development of cancer cachexia. PURPOSE: The purpose of this exploratory study was to investigate alterations in liver metabolism by examining measures of hepatic glycogen storage, oxidative phenotype and lipid content throughout the …

Physiological Studies Of Heat Stress Acclimation During A Specific Exercise Regimen, Leland F. Morgans, Alan M. Johnson
Journal of the Arkansas Academy of Science
Eleven subjects were used to determine if the exercise regimen of racquetball could be used as a heat stress acclimator. Core temperature, skin temperature, sweat production, and weight loss were recorded during a racquetball match. Skin and core temperatures were determined by using thermistors. Sweat was collected with modified stress electrodes. Weight loss was recorded by comparing nude weights at the beginning and end of a match. The results indicated that an hour of strenuous racquetball play caused a significant increase in core temperature with subsequent sweating which resulted in a significant decrease in skin temperature and weight loss. The …
