Diffusion Barriers Of The Lateral Ventricular System, Anitha Saravanakumar

Master's Theses

Adult neurogenesis in mammalian brain has become a well-accepted phenomenon. The neural stem cells in the sub ventricular zone (SVZ) along the lateral wall of the lateral ventricle, the largest germinal center of adult neurogenesis, are maintained by the neural stem cell niche. One prominent feature of the niche is its close proximity to the cerebral spinal fluid (CSF). The role of micromolecules (such as ions, water and gases) present in the CSF and diffusing through the lateral ventricular wall and how the stem cell micro-environment is maintained is poorly understood. The cytoarchitecture of the lateral ventricular wall with a …

Binge Ethanol Leads To Decreased Macrophage Accumulation In Infected Cutaneous Wounds, Sara Hlavin

Master's Theses

Trauma patients who consumed alcohol prior to sustaining injuries have higher rates of morbidity and mortality than those with comparable injuries who did not drink. Additionally, those who drank had impaired wound healing and increased susceptibility to infection. Despite these clinical observations, few studies have explored the effect of ethanol on the innate immune cell function in a healing wound or how this may alter resolution of cutaneous infection. A murine model of ethanol and cutaneous wound infection was used to examine bacterial growth and recruitment of innate immune cells. Mice were given either ethanol (2.2 g/kg) or saline 30 …

Urinary Antimicrobial Peptides And The Urinary Microbiota In A Uti-Susceptible Population Of Female Pelvic Floor Surgery Patients, Vanessa Nienhouse

Master's Theses

Urinary tract infections (UTI)s are a national priority. Women who undergo surgery for pelvic floor disorders such as pelvic organ prolapse (POP) or urinary incontinence (UI) are at increased risk for UTI, as 10-30% will contract a post-instrumentation UTI (postI-UTI) within six weeks after surgery. Currently, the factors that contribute to the high rate of postI-UTI are unknown, and there is currently no clinical assessment to identify at-risk patients. However, antimicrobial peptides (AMPs) and characteristics of the urinary microbiota have the potential to serve as biomarkers, identifying patients at UTI risk and facilitating clinical prevention studies.

While it was previously …
