The Prevalence Of Diabetes In Juveniles, Tatyana Johnson Jul 2023

The Prevalence Of Diabetes In Juveniles, Tatyana Johnson

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Diabetes mellitus, simply known as diabetes, is a metabolic disorder that impacts how the body makes use of glucose or blood sugar. Glucose is the primary supply of energy for the body’s cells, which is controlled by insulin, a pancreatic hormone. Diabetes results in high blood glucose levels (hyperglycemia), which are caused by either insufficient insulin production by the pancreas or ineffective insulin utilization by the body (Dean & McEntyre, 2004). Although there are several types of diabetes, the two main types are type 1 and type 2. Type 1, also known as juvenile diabetes, is an inflammatory condition in …

Sexual Dimorphism Of Glomerular Capillary Morphology In Rats, Zackarias Coker May 2023

Sexual Dimorphism Of Glomerular Capillary Morphology In Rats, Zackarias Coker

Undergraduate Honors Theses

Chronic kidney disease (CKD) progresses faster in males than females; however, the underlying mechanisms remain poorly understood. Sex differences in glomerular capillary morphology has been hypothesized to contribute, in part, to the increased susceptibility to hypertension-induced renal injury and CKD progression in males, but this has not been investigated. The goal of the present study was to assess glomerular capillary morphology in male vs. female rats with intact kidneys and after uninephrectomy (UNX). We hypothesized that glomerular capillary radii (RCAP) and length (LCAP) would be greater in male rats.

Male (n=4) and female (n=4) with intact …


Multiparametric Magnetic Resonance Imaging Artificial Intelligence Pipeline For Oropharyngeal Cancer Radiotherapy Treatment Guidance, Kareem Wahid May 2023

Multiparametric Magnetic Resonance Imaging Artificial Intelligence Pipeline For Oropharyngeal Cancer Radiotherapy Treatment Guidance, Kareem Wahid

Dissertations & Theses (Open Access)

Oropharyngeal cancer (OPC) is a widespread disease and one of the few domestic cancers that is rising in incidence. Radiographic images are crucial for assessment of OPC and aid in radiotherapy (RT) treatment. However, RT planning with conventional imaging approaches requires operator-dependent tumor segmentation, which is the primary source of treatment error. Further, OPC expresses differential tumor/node mid-RT response (rapid response) rates, resulting in significant differences between planned and delivered RT dose. Finally, clinical outcomes for OPC patients can also be variable, which warrants the investigation of prognostic models. Multiparametric MRI (mpMRI) techniques that incorporate simultaneous anatomical and functional information …


Examining Ndufab1 Expression In Head And Neck Squamous Cell Carcinoma, Addison L. Stevens May 2023

Examining Ndufab1 Expression In Head And Neck Squamous Cell Carcinoma, Addison L. Stevens

Undergraduate Honors Theses

Head and neck squamous cell carcinoma (HNSCC) accounts for around 4% of all cancers in the USA. HNSCC includes cancers of the oral cavity, oropharynx, nasopharynx, hypopharynx, and larynx. Reprogramming of mitochondrial metabolism has been known to promote oncogenesis. NDUFAB1, a nuclear encoded subunit of respiratory complex I (RCI) in the inner mitochondrial membrane, is abundantly expressed at the mRNA level in HNSCC patients. Based on this finding, we hypothesize that NDUFAB1 protein expression is high in HNSCC and that NDUFAB1 expression predicts a poor prognosis in HNSCC patients. We determined NDUFAB1 expression in HNSCC using immunohistochemistry and pathology guided …
