New Insights Into Post-Sepsis Muscle Weakness Elucidated Using A Novel Animal Model, Allison M. Steele

Theses and Dissertations--Physiology

Sepsis is a severe life-threatening critical illness that damages multiple physiological systems. After hospital discharge, more than 70% of severe sepsis survivors report profound weakness which significantly impacts quality of life. Such weakness gives rise to new limitations of daily living, which ultimately leads to loss of independence in many patients. Despite wide recognition of this serious issue by clinicians and researchers alike, the mechanisms contributing to chronic skeletal muscle dysfunction after sepsis are not well understood. Lack of progress in this field is largely due to the absence of an appropriate animal model; current models are either too mild …

Tumor-Derived Proteins And Mitochondrial Dysfunction In Lung Cancer-Induced Cachexia, Julie B. Mclean

Theses and Dissertations--Physiology

Lung tumors secrete multiple factors that contribute to cachexia, a severe wasting syndrome that includes loss of muscle mass, weakness, and fatigue. 80% of advanced lung cancer patients experience cachexia, which cannot be reversed by nutritional interventions, diminishes response to and tolerance of cancer treatments, and increases morbidity and mortality. Despite a multitude of clinical trials, there are currently no approved treatments. This deficiency suggests that not all of the factors that contribute to cachexia have been identified.

Cancer is frequently accompanied by an increase in cyclooxygenase-2 (COX-2), a hallmark of inflammation. Clinical trials for COX-2 inhibitors have resulted in …

Attenuating Trigeminal Neuropathic Pain By Repurposing Pioglitazone And D-Cycloserine In The Novel Trigeminal Inflammatory Compression Mouse Model, Danielle N. Lyons

Theses and Dissertations--Physiology

Approximately 22% of the United States population suffers from a chronic orofacial pain condition. One such condition is known as trigeminal neuropathic pain frequently reported as continuous aching and burning pain, often accompanied by intermittent electrical shock-like sensations. Dental procedures or trauma are known causes of peripheral trigeminal nerve injury and inflammation. Patients who have this type of facial pain also suffer from emotional distress. For these reasons, trigeminal neuropathic pain needs to be studied in more detail to improve the understanding of the etiology and maintenance of this condition, as well as to develop effective treatment strategies. The first …
