Biomedical Sciences

Serotonin reuptake inhibitors (SSRIs) are commonly prescribed to pregnant women experiencing depression. Such drugs, however, might adversely affect placenta and fetal brain development. Parietal trophoblast giant cells (pTGCs) in the mouse placenta are postulated to internalize maternal serotonin (5-HT) via transport through SERT, encoded by Slc6a4, and to provide the initial source of 5-HT to the emerging brain via the placental–brain axis. Genetic deletion of Slc6a4 in pTGCs has been hypothesized to impact placental and fetal brain development. A transgenic mouse line with high-affinity SERT, encoded by Slc6a4, was selectively deleted by pairing mice with Cre recombinase linked …

Presented at the ASHP Midyear Clinical Meeting. New Orleans, LA

This evaluation found that among patients who experienced eosinophilia, only one exhibited signs of hypersensitivity, while seven required a change in therapy. This indicates that while eosinophilia is a concern, its direct clinical impact may be limited for the majority of patients. In the cohort experiencing elevated LFTs including AST, ALT, or alkaline phosphatase levels, fewer than 2% necessitated a change in therapy. This low rate suggests that routine LFT monitoring may not always correlate with significant clinical decisions, raising questions about the necessity of frequent lab draws.

School of Graduate Studies Faculty Publications

Leukemia-associated RhoGEF (LARG) is a guanine nucleotide exchange factor (GEF) known for its specificity toward Ras homolog family member A (RhoA). LARG plays a crucial regulatory role in various cellular processes such as migration, proliferation, invasion, and metastasis by facilitating the exchange of GDP to GTP on RhoA. Phosphorylation of LARG at S1288 by ribosomal S6 kinase 2 (RSK2) promotes RhoA activation. However, the precise mechanism remains unclear. Here, we demonstrate the essential role and mechanism by which S1288 phosphorylation facilitates LARG-mediated invasiveness in response to epidermal growth factor (EGF). Upon EGF stimulation, RSK2 phosphorylates LARG at S1288, thereby promoting …

Recovery And Characterization Of Moraxella Species From Bovine Specimens, Laura G. Leger

School of Veterinary and Biomedical Sciences: Dissertations, Theses, and Student Research

The family Moraxellaceae is made up of a diverse group of 24 named species that fall into three phylogenetic groups. While most Moraxella spp. act as commensal respiratory and/or ocular flora of mammals, some are associated with disease. One of these diseases, infectious bovine keratoconjunctivitis (IBK), has significant welfare and economic impacts to both cattle and cattle producers. Moraxella bovis is the only experimentally determined cause of IBK, however, an association of Moraxella bovoculi with disease has been proposed. Currently, available vaccines do not have high levels of efficacy in the field. Culture based methods are the gold standard for …

PURPOSE: To develop a dual-level pattern tree to characterize visual field (VF) loss subtypes that can be used to better predict glaucoma progression and glaucoma polygenic risk scores (PRSs).

METHODS: This study included 113,030 patients from three datasets, each used for a specific purpose: (1) model training, (2) progression forecasting, and (3) PRS correlations. We applied archetypal analysis to cluster 24-2 VFs into trunk patterns and their branch patterns. The Cox regression model was used to forecast VF progression using mean deviation (MD) slope, MD-fast slope, total deviation (TD) pointwise slope, and visual field index (VFI) slope. Multivariable regression analyses …
