A Germline Variant At 8q24 Contributes To Familial Clustering Of Prostate Cancer In Men Of African Ancestry, Burcu F Darst, Adam S Kibel, Bettina F Drake, Et Al.

2020-Current year OA Pubs

Although men of African ancestry have a high risk of prostate cancer (PCa), no genes or mutations have been identified that contribute to familial clustering of PCa in this population. We investigated whether the African ancestry-specific PCa risk variant at 8q24, rs72725854, is enriched in men with a PCa family history in 9052 cases, 143 cases from high-risk families, and 8595 controls of African ancestry. We found the risk allele to be significantly associated with earlier age at diagnosis, more aggressive disease, and enriched in men with a PCa family history (32% of high-risk familial cases carried the variant vs …

First-Time Practicum Students' Lived Experiences Of Case Presentations In Group Supervision: A Phenomenological Study, Jason Blakely Fischer

Dissertations

Although best practices of group supervision advise that supervisory methods match the developmental level of supervisees, research has shown that novices typically receive group supervision in the same manner as more experienced trainees. The prevalent use of case presentations in group supervision regardless of learners' level of clinical experience suggests contemporary practicum courses may be overlooking beginning students' unique, developmental characteristics and needs. Fifteen counseling students enrolled in CACREP-accredited master's degree programs across the United States were interviewed for a phenomenological study exploring their experiences of case presentations in practicum. Synchronous interviews conducted over video conferencing examined participants' emotional experiences …

Literature Review On Drosophila Research In Parkinson’S Disease, Maryann Jaquith

Honors Projects

Parkinson’s disease (PD) is one of the most prevalent neurodegenerative diseases. It is characterized by its main symptom of a tremor that usually starts in one limb. The four cardinal symptoms of PD are tremor, rigidity, bradykinesia, and postural instability. While the four cardinal symptoms are all motor symptoms there are non-motor symptoms for PD which include cognitive changes, sleeping disorders, lightheadedness, early satiety, and mood disorders. PD is characterized by dopaminergic (DA) neuron loss and the accumulation of Lewy bodies (LB) which are predominantly composed of α-synuclein (α-Syn) protein.

α-Syn is a protein found abundantly in the brain. It …

Factors Associated With Stunting And Wasting In Children Under 2 Years In Bangladesh, Tuhinur Rahman Chowdhury, Sayan Chakrabarty, Muntaha Rakib, Sabiha Afrin, Sue Saltmarsh, Stephen Winn

Research outputs 2014 to 2021

© 2020 Child undernutrition has been a major concern for Bangladesh as it is amongst the highest stunting and wasting prevalent countries in the world. The objective of our study was to explore the socioeconomic determinants of stunting and wasting in children under two years. This study explored nationally representative sample of 7,230 children ranging in age from 0 to < 24 months using two separate binary logistic regression models to determine the risk factors associated with child stunting and wasting. Our study estimated approximately 33 percent children to be stunted and 11 percent to be wasted. Our analysis found that, 12 to < 24 months old children's height-for-age-z-score and weight-for-height-z-score deteriorated in comparison to those of below 6 months. Female children had significantly lower odds of stunting and wasting compared with male children. Study revealed that children from wealthier families were at lower risk of being stunted and wasted compared to children from poorer households. Parental education was determined as a significant predictor of stunting. Children who lived in Sylhet division were 1.26 times more likely to be stunted than the children of Dhaka division [OR = 1.26; 95% CI: 1.02–1.55]. Our study revealed age, gender, geographic distribution, and household's position in wealth index as common determinants of child stunting and wasting in Bangladesh. While parental education was significant predictor for child stunting, type of toilet facility was found as statistically significant determinant of child wasting in children of less than two years age.

The Role Of Glia In Protein Aggregation, Qingyun Li, Michael S Haney

2020-Current year OA Pubs

Protein aggregation diseases involve intracellular accumulation or extracellular deposition of certain protein species in neuronal or glial cells, leading to neurodegeneration and shortened lifespan. Prime examples include Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), and Huntington's disease (HD), which are affected by overlapping or specific aggregation-prone proteins. Mounting evidence suggests that dysfunctional glial cells may be major drivers for some diseases, and when they are not causal factors, they could still significantly exacerbate or alleviate disease progression by playing a plethora of detrimental or beneficial roles. Here we review the diverse functions performed by glial cells in …

Integrating Affect Perception Tasks From The New York Emotion Battery Into A Comprehensive Measure Of Neuropsychological Change Across The Lifespan, Melinda A. Cornwell

Dissertations, Theses, and Capstone Projects

Background: The ability to perceive others’ emotions is a vital skill for social competency, impacting the success of personal and professional relationships (Brinton & Fujiki, 2011; Cassidy et al., 1992; Côté & Miners, 2006). According to Socioemotional Selectivity Theory (SST; Carstensen, 1991), human motivation develops to become more discerning in choosing milieus that yield the most gratifying return on the investment of personal resources (e.g., time, attention, and effort), perhaps explaining why some research findings indicate that older adults may demonstrate an affect perception (AP) bias described as a positivity effect (Reed et al., 2014). Moreover, AP predicts cognitive and …
