Determining The Role Of Satellite Cells During Skeletal Muscle Adaptation, Davis A. Englund

Theses and Dissertations--Rehabilitation Sciences

Physical inactivity, advancing age, limb immobilization, degenerative diseases and various systemic diseases (many cancers, sepsis, HIV, COPD, kidney disease) all lead to skeletal muscle wasting. The loss of muscle mass is of major clinical importance because it leads to an increased risk for morbidity, disability, and the loss of independence; collectively contributing to a substantive increase in healthcare utilization and cost. The prevalence of cachexia (disease-induced muscle wasting) can reach as high as 80% in certain patient populations and the average cost per hospital stay is $4,641 more than in non-cachectic patients. Direct healthcare costs attributable to sarcopenia were estimated …

Offspring And Maternal Health Benefits Of Exercise During Pregnancy, Lindsay G. Carter

Theses and Dissertations--Nutritional Sciences

Maternal lifestyle and nutrient intake during pregnancy can have long-lasting effects on the health of offspring as well as the mother. This dissertation focuses on the impact of maternal exercise during pregnancy on offspring insulin sensitivity and glucose uptake and the maternal effects of exercise during pregnancy.

The first aim of this dissertation was to investigate if exercise prior to and during pregnancy and nursing would improve glucose uptake and insulin sensitivity in mice and rats. In both mice and rats, it was concluded that maternal exercise could enhance whole-body insulin sensitivity and increase glucose uptake into skeletal muscle and …

Thermal Sensitivity Of Vagal Pulmonary Sensory Neurons: Role Of Transient Receptor Potential Vanilloid Channels, Dan Ni

University of Kentucky Doctoral Dissertations

Hyperthermia can occur in lungs and airways during both physiological and pathophysiological conditions. A previous study carried out in our laboratory showed that hyperthermia activates and sensitizes vagal bronchopulmonary Cfiber afferents, whether this effect is through a direct action of hyperthermia on sensory nerves is not known. This dissertation study was aimed to investigate the thermal-sensitivity of pulmonary sensory neurons, and the roles of thermalsensitive transient receptor potential vanilloid (TRPV) channels. Whole-cell patch-clamp recordings of neurons isolated from nodose/jugular ganglia were applied in the study. Results of this study showed that hyperthermia directly activates pulmonary sensory neurons, and this effect …
