Ultrasound Elasticity Measurements As A Predictor For Arteriovenous Fistula Maturation, Anna Sorace
Ultrasound Elasticity Measurements As A Predictor For Arteriovenous Fistula Maturation, Anna Sorace

This research thesis examines the applicability of using ultrasound imaging to quantify arterial elasticity and assess potential of arteriovenous fistula maturation in chronic kidney disease (CKD) patients. Tissue-specific abnormalities have proven useful for identifying disease states within oncology, cardiovascular and musculoskeletal system. Using ultrasound-based imaging to evaluate arterial elasticity is a noninvasive and novel technique. It has the potential to contribute further insight into chronic kidney disease fistula failure and become a noninvasive prognostic indicator. Reliable vascular access is critical for delivery of adequate hemodialysis treatment to CKD patients and to maintain long-term connections for dialysis. An arteriovenous fistula is …

A recent focus of psychiatric research is estrogen related mood disorders such as postpartum depression and major depressive disorder in women. It is now clear that women are more susceptible to depression in response to stress during reproductive events when ovarian hormones are low or fluctuating. Depressive episodes are characterized by feelings of helplessness and despair as well as learning and memory impairments that have been linked to the hippocampus. Thus, decreased functioning of hippocampal circuits likely contributes to the cognitive symptoms associated with depression. Preclinical research shows that stress, which triggers depressive episodes, decreases the ability of excitatory synapses …

Temperature is considered a very important abiotic factor in fish communities. An increase in water temperature, as is found with the use of nuclear production reactors, can act as a stressor in aquatic systems. The P-reactor, operational from 1954-1988, on the Savannah River Site near Aiken, South Carolina, utilized the Par Pond Reservoir System as part of its cooling mechanisms. During reactor operation, heated effluents were displaced into Pond C, causing the water to be heated to around 45° C. Fischer (1994) found that the bluegill population had adapted with changes to their morphology and physiology. The bluegill from the …

The Impact Of Stressful Neighborhoods On The Mental Health Of Emerging Adolescents, Vicki P. Winstead

Life within the ecological context of a disadvantaged and disordered neighborhood is characterized by daily exposure to chronic stressors which are often outside the realm of control of the individual and have negative consequences for the mental health of its residents and in particular, adolescents Using data from Healthy Passages, a multilevel, multi-method longitudinal study which examines health trajectories of adolescents over a ten year period, this paper examines whether daily exposure to a threatening environment in disadvantaged and disordered neighborhoods lead to depression in young people who are on the verge of adolescence. The current study tested the relationships …
