The Vegetarian/Flexitarian Diet, Derek C. Miketinas, Catherine M. Champagne Jan 2023

The Vegetarian/Flexitarian Diet, Derek C. Miketinas, Catherine M. Champagne

Population and Public Health Science Faculty Publications

Vegetarian diets are gaining popularity in the United States, although only a small fraction of the adult population follows some version of a vegetarian diet. Plant-based diets are heterogeneous in practice. Well-planned vegetarian and flexitarian diets can be healthy and reduce the risk of many chronic diseases. Unstructured vegetarian diets can be deficient in some nutrients like protein, omega-3 fatty acids, calcium, iron, zinc, vitamin B12, and vitamin D.

Rbp4-Gal4, A Germline Driver That Activates In Meiosis, Reveals Functions For Vcp In Spermatid Development, Tyler J. Butsch, Alyssa E. Johnson, K. Adam Bohnert Jan 2023

Rbp4-Gal4, A Germline Driver That Activates In Meiosis, Reveals Functions For Vcp In Spermatid Development, Tyler J. Butsch, Alyssa E. Johnson, K. Adam Bohnert

Faculty Publications

Valosin-containing protein (VCP) is a versatile and ubiquitously expressed AAA+ ATPase that regulates multiple stages of Drosophila spermatogenesis. While VCP has documented roles in mitotic spermatogonia and meiotic spermatocytes, it is also highly expressed in post-meiotic spermatids, suggesting potential late-stage developmental functions as well. However, tools to assess late-stage activities of pleiotropic spermatogenesis genes such as VCP are lacking. Available germline-specific Gal4 drivers activate in stem cells or spermatogonia; consequently, knocking down VCP using one of these drivers disrupts or blocks early germ-cell development, precluding analysis of VCP in later stages. A Gal4 driver that activates later in development, such …

Multi-Shell Dmri Estimation From Single-Shell Data Via Deep Learning, Reagan Dugan, Owen Carmichael Jan 2023

Multi-Shell Dmri Estimation From Single-Shell Data Via Deep Learning, Reagan Dugan, Owen Carmichael

Clinical Research Faculty Publications

Diffusion magnetic resonance imaging (dMRI) data acquired with multiple diffusion gradient directions and multiple b-values (“multi-shell” data) enables compartmental modeling of brain tissues as well as enhanced estimation of white matter fiber orientations via the orientation distribution function (ODF). However, multi-shell dMRI acquisitions are time consuming, expensive and difficult in certain clinical populations. We present a method to estimate high b-value volumes from low b-value volumes via deep learning. A 3-dimensional U-NET architecture is trained from multi-shell dMRI training data to synthesize a high b-value volume from a diffusion gradient direction, given a low b-value volume from that same gradient …

Apathy is one of the most common neuropsychiatric symptoms (NPS) and is associated with poor clinical outcomes. Research that helps define the apathy phenotype is urgently needed, particularly for clinical and biomarker studies. We used latent class analysis (LCA) with two independent cohorts to understand how apathy and depression symptoms co-occur statistically. We further explored the relationship between latent class membership, demographics, and the presence of other NPS. The LCA identified a four-class solution (no symptoms, apathy, depression, and combined apathy/depression), reproducible over both cohorts, providing robust support for an apathy syndrome distinct from depression and confirming that an apathy/depression …

Clinical Research Faculty Publications

Introduction: Effective connectivity (EC), the causal influence that functional activity in a source brain location exerts over functional activity in a target brain location, has the potential to provide different information about brain network dynamics than functional connectivity (FC), which quantifies activity synchrony between locations. However, head-to-head comparisons between EC and FC from either task-based or resting-state functional MRI (fMRI) data are rare, especially in terms of how they associate with salient aspects of brain health. Methods: In this study, 100 cognitively-healthy participants in the Bogalusa Heart Study aged 54.2 ± 4.3years completed Stroop task-based fMRI, resting-state fMRI. EC and …

Introduction: Educational attainment, widely used in epidemiologic studies as a surrogate for socioeconomic status, is a predictor of cardiovascular health outcomes. Methods: A two-stage genome-wide meta-analysis of low-density lipoprotein cholesterol (LDL), high-density lipoprotein cholesterol (HDL), and triglyceride (TG) levels was performed while accounting for gene-educational attainment interactions in up to 226,315 individuals from five population groups. We considered two educational attainment variables: “Some College” (yes/no, for any education beyond high school) and “Graduated College” (yes/no, for completing a 4-year college degree). Genome-wide significant (p < 5 × 10−8) and suggestive (p < 1 × 10−6) variants were identified in Stage 1 (in up to 108,784 individuals) through genome-wide analysis, and those variants were followed up in Stage 2 studies (in up to 117,531 individuals). Results: In combined analysis of Stages 1 and 2, we identified 18 novel lipid loci (nine for LDL, seven for HDL, and two for TG) by two degree-of-freedom (2 DF) joint tests of main and interaction effects. Four loci showed significant interaction with educational attainment. Two loci were significant only in cross-population analyses. Several loci include genes with known or suggested roles in adipose (FOXP1, MBOAT4, SKP2, STIM1, STX4), brain (BRI3, FILIP1, FOXP1, LINC00290, LMTK2, MBOAT4, MYO6, SENP6, SRGAP3, STIM1, TMEM167A, TMEM30A), and liver (BRI3, FOXP1) biology, highlighting the potential importance of brain-adipose-liver communication in the regulation of lipid metabolism. An investigation of the potential druggability of genes in identified loci resulted in five gene targets shown to interact with drugs approved by the Food and Drug Administration, including genes with roles in adipose and brain tissue. Discussion: Genome-wide interaction analysis of educational attainment identified novel lipid loci not previously detected by analyses limited to main genetic effects.

Biochemical Alterations In The Follicular Fluid Of Bovine Peri-Ovulatory Follicles And Their Association With Final Oocyte Maturation, Noof Abdulrahman Alrabiah, Constantine A. Simintiras, Alexander C.O. Evans, Patrick Lonergan, Trudee Fair

Faculty Publications

Follicular fluid (FF), a product of vascular transudate and granulosa and thecal cell secretions, is the milieu that has evolved to support oocyte growth and maturation which plays a central role in oocyte quality determination. Therefore, a suboptimal FF composition may be reflected in compromised oocyte progression through maturation, fertilization, or embryo development. To date, the composition of bovine FF remains understudied. To address this, we comprehensively characterized the metabolomic constituency of bovine FF in the period during which the oocyte undergoes meiotic maturation. More specifically, FF from pre (-24 h) and peri (-2 h)-ovulatory follicles was profiled by high-throughput …

Aflatoxin (AF) contamination, caused by Aspergillus flavus, compromises the food safety and marketability of commodities, such as maize, cotton, peanuts, and tree nuts. Multigenic inheritance of AF resistance impedes conventional introgression of resistance traits into high-yielding commercial maize varieties. Several AF resistance-associated quantitative trait loci (QTLs) and markers have been reported from multiple biparental mapping and genome-wide association studies (GWAS) in maize. However, QTLs with large confidence intervals (CI) explaining inconsistent phenotypic variance limit their use in marker-assisted selection. Meta-analysis of published QTLs can identify significant meta-QTLs (MQTLs) with a narrower CI for reliable identification of genes and linked markers …

The Inheritance Of Energy And The Evolution Of Unsustainability, Brian Snyder Jan 2023

The Inheritance Of Energy And The Evolution Of Unsustainability, Brian Snyder

Faculty Publications

Across contemporary and historical human groups, there is variation in how cultures interact with the environment and this variation is inherited through culture. Some human-environment relationships maximize group fitness relative to other relationships. Thus, there is heritable, fitness-associated variation in human-environment interactions and so human-environment interactions may be understood to be an evolved trait. However, one fitness-maximizing human-environment relationship could be unsustainable resource extraction. Anthroecological theory proposes that human cultures and genotypes have been selected for unsustainability, although several mechanisms have been proposed for how this selection may have worked.
