The Deleterious F109s Mutation Disrupts Binding Of Sex-Determining Region Y With Dna, Mohammed Baqur S. Al-Shuhaib Mbsa

Karbala International Journal of Modern Science

Sex-determining region Y (SRY) protein is the master switch in the initiation of male sex differentiation. Mutation in SRY gene results in ambiguous genitalia and abnormalities in reproductive organs. Its function is mainly controlled by its high mobility group (HMG) box. Damage to the HMG box may cause dysfunction of the SRY protein, which may, in turn, lead to sex reversal. This study was conducted to prioritize the deleterious effects of the non-synonymous single nucleotide polymorphisms (nsSNPs) on SRY protein. A series of computational tools were applied to predict nsSNPs with the most harmful effects on protein structure, function, and …

Faculty Research 2020

N-Glycanase 1 (NGLY1) is a cytoplasmic deglycosylating enzyme. Loss-of-function mutations in the NGLY1 gene cause NGLY1 deficiency, which is characterized by developmental delay, seizures, and a lack of sweat and tears. To model the phenotypic variability observed among patients, we crossed a Drosophila model of NGLY1 deficiency onto a panel of genetically diverse strains. The resulting progeny showed a phenotypic spectrum from 0 to 100% lethality. Association analysis on the lethality phenotype, as well as an evolutionary rate covariation analysis, generated lists of modifying genes, providing insight into NGLY1 function and disease. The top association hit was Ncc69 (human NKCC1/2 …

Feasibility Of Continuous Fever Monitoring Using Wearable Devices, Benjamin L. Smarr, Kirstin Aschbacher, Sarah M. Fisher, Anoushka Chowdhary, Stephan Dilchert, Karena Puldon, Adam Rao, Frederick M. Hecht, Ashley E. Mason

Publications and Research

Elevated core temperature constitutes an important biomarker for COVID-19 infection; however, no standards currently exist to monitor fever using wearable peripheral temperature sensors. Evidence that sensors could be used to develop fever monitoring capabilities would enable large-scale health-monitoring research and provide high-temporal resolution data on fever responses across heterogeneous populations. We launched the TemPredict study in March of 2020 to capture continuous physiological data, including peripheral temperature, from a commercially available wearable device during the novel coronavirus pandemic. We coupled these data with symptom reports and COVID-19 diagnosis data. Here we report findings from the first 50 subjects who reported …

Effects Of Chronic Stress On Anxiety-Like Behavior And Fear Learning In The Tgf344-Ad Rat Model Of Alzheimer’S Disease, Samuel James Bouquin

Psychology ETDs

Alzheimer’s disease (AD) is a progressive neurodegenerative brain disorder that leads to severe cognitive and functional impairments. Many AD patients also exhibit neuropsychiatric symptoms (NPS) such as anxiety and prior to the clinical diagnosis of dementia. The prodromal manifestation of NPS is highly prevalent among patients with mild cognitive impairment (MCI), and the co-occurrence of preclinical NPS and MCI is associated with an increased risk of developing AD. Prolonged or repeated exposure to stress can result in behavioral disturbances (e.g., anxiety) and accelerated global cognitive decline. Importantly, AD patients exhibit altered stress systems and AD-related neuropathology has been linked to …

Insights Into Insular Isolation Of The Bull Shark, Carcharhinus Leucas (Müller And Henle, 1839), In Fijian Waters, Kerstin B J Glaus, Sharon A. Appleyard, Brian Stockwell, Juerg M. Brunnschweiler, Mahmood S. Shivji, Eric Clua, Amandine D. Marie, Ciro Rico

Biology Faculty Articles

The bull shark (Carcharhinus leucas) is a large, mobile, circumglobally distributed high trophic level predator that inhabits a variety of remote islands and continental coastal habitats, including freshwater environments. Here, we hypothesize that the barriers to dispersal created by large oceanic expanses and deep-water trenches result in a heterogeneous distribution of the neutral genetic diversity between island bull shark populations compared to populations sampled in continental locations connected through continuous coastlines of continental shelves. We analyzed 1,494 high-quality neutral single nucleotide polymorphism (SNP) markers in 215 individual bull sharks from widespread locations across the Indian and Pacific Oceans …

Reviewing Pesticide Impacts On Frogs To Suggest Management Applications In The Gambles Mill Eco-Corridor, Marc Gorman

Environmental Studies Senior Seminar Projects

For years, frog populations have been declining due to a variety of anthropogenic sources, including pesticide use. Pesticides work by inhibiting bodily functions in their target pest species, though they frequently have unintentional impacts on other life forms in an ecosystem. Some researchers have evaluated these effects, but their studies mainly focus on finding an LC50 - a concentration that will kill 50% of their test species sample. However, these LC50 levels are often higher than what would be found in nature, and pesticides have been shown to still impact species at lower concentrations. Thus, this study attempted to summarize …

Probing The Impacts Of Ultra-Low Platinum Loadings On Membrane Degradation Mechanisms, Andre J. Spears

Nanoscience and Microsystems ETDs

Membrane chemical degradation is one of many factors that can impact fuel cell durability. The fuel cell’s performance and lifetime heavily depends on the membrane and its ability to maintain chemical and mechanical integrity. In Nafion^® membranes, hydroxyl radicals are the primary cause of chemical membrane degradation as they attack the membrane’s polymer structure. Radical formation can ensue via peroxide decomposition at the cathode or gases reacting on Pt particles or contaminants like Fe (a fenton's reagent) within the membrane. As radicals attack the membrane’s polymer structure the membrane thins, and fluoride and sulfate ions are released. This consequently …

Fda Regulation Impact On Early Stage Medical Device Innovation In Academia, Keyana Fariello

Theses

The commercialization of medical products at the university level is a multilayered and challenging process. One barrier to commercialization is the difficulty of meeting Food and Drug Administration (FDA) regulatory requirements. Regulations and standards are undoubtedly necessary to maintain the highest product safety levels, but it creates many obstacles. This paper will analyze how researchers involved with early-stage medical device innovation in a university setting deal with FDA compliance issues and the implications of this engagement for innovation. I conducted an exploratory case study of ten medical product development projects at the Rochester Institute of Technology (RIT). Overall, I found …
