Previously, the Genetics Initiative genome-wide association study used common variants to identify multiple loci associated with However, largest impact on outcomes are expected be rare in population. Hence, studying may provide additional insights into disease susceptibility and pathogenesis, thereby informing therapeutics development. Here, we combined whole-exome whole-genome sequencing from 21 cohorts across 12 countries performed...
COVID-19 vaccines are safe and highly effective, but some individuals experience unpleasant reactions to vaccination. As the majority of adults in United States have received a vaccine this year, there is an unprecedented opportunity study genetics vaccination via surveys who already part genetic research studies. Here, we queried 17,440 participants Helix DNA Discovery Project Healthy Nevada about their Our genome-wide association identifies between severe difficulties with daily routine...

Chronic exposure to high levels of arsenic in drinking water can have wide-ranging health effects and is a global concern. The domestic well population the western Great Basin (WGB) at increased risk due hydrologic, geologic, climatic setting region. A logistic regression (LR) model was developed predict probability elevated (≥5 μg/L) alluvial aquifers assess potential geologic hazard level posed populations. Alluvial are susceptible contamination, which concern because they primary source...
Respiratory ammonification and denitrification are two evolutionarily unrelated dissimilatory nitrogen (N) processes central to the global N cycle, activity of which is thought be controlled by carbon (C) nitrate (NO3-) ratio. Here we find that Intrasporangium calvum C5, a novel dual-pathway denitrifier/respiratory ammonifier, disproportionately utilizes rather than when grown under low C concentrations, even at C:NO3- ratios. This finding in conflict with paradigm high ratios promote...
Background: Interventions are needed to help people reduce exposure harmful chemicals from everyday products and lifestyle habits. Report-back of individual exposures is a potential pathway increasing environmental health literacy (EHL) readiness exposures. Objectives: Our objective was determine if report-back endocrine-disrupting (EDCs) can EDC exposure, increase EHL, change (i.e., implement exposure-reduction behaviors). Methods: Participants in the Healthy Nevada Project completed EHL...
Background: Daily-use products, including personal care household and dietary supplements, often contain ingredients that raise concerns regarding harmful chemical exposure. Endocrine-disrupting chemicals (EDCs) found in daily-use products are associated with numerous adverse health effects. Methods: This pilot study explores the relationship between concentrations of EDCs urine samples used 24 h prior to sample collection, concern those 140 adults reproductive age Northern Nevada. Results:...
Prochlorococcus is a globally abundant marine cyanobacterium with many adaptations that reduce cellular nutrient requirements, facilitating growth in its nutrient-poor environment. One such genomic adaptation the preferential utilization of amino acids containing fewer N-atoms, which minimizes nitrogen requirements. We predicted transcriptional regulation might further N budgets during transient limitation. To explore this, we compared transcription start sites (TSSs) MED4 under N-deprived...
Adverse Childhood Experiences are stressful and traumatic events occurring before the age of eighteen shown to cause mental physical health problems, including increased risk obesity. Obesity remains an ongoing national challenge with no predicted solution. We examine a subset Healthy Nevada Project, focusing on multi-ethnic cohort 15,886 sequenced participants recalled adverse childhood events, study how ACEs their genotype-environment interactions affect BMI. Specifically, Project by Helix...

With some exceptions, the deep fractured rock ecosystems across most of North America have not been studied extensively. However, US Great Basin, in particular Nevada National Security Site (NNSS, formerly Test Site), has hosted a number influential subsurface investigations over years. This study focuses on resident microbiota within fluids extracted from monitoring borehole U-3cn#5 at depth 691 meters below land surface, which intercepts hydrogeological confined aquifer Paleozoic carbonate...
As complex mental health traits and life histories are often poorly captured in hospital systems, the utility of using Barratt Impulsivity Scale (BIS) Adverse Childhood Experiences (ACEs) for assessing adult disease risks is unknown. Here, we use participants from Healthy Nevada Project (HNP) to determine if two standard self-assessments could predict incidence onset disease. We conducted a retrospective cohort study involving who completed Behavioral Mental Health Self-Assessment (HDSA)...
The purpose of this study was to determine whether extracellular matrix (ECM) composition through integrin receptors modulated the volume-sensitive osmolyte anion channels (VSOACs) in skeletal muscle-derived C2C12 cells. Cl(-) currents were recorded whole cell voltage-clamped cells grown on laminin (LM), fibronectin (FN), or absence a defined ECM (NM). Basal membrane isotonic media (300 mosmol/kg) larger FN (3.8-fold at +100 mV) LM (8.8-fold when compared with NM. VSOAC activated by exposure...
The clinical value of population-based genetic screening projects depends on the actions taken findings. Healthy Nevada Project (HNP) is an all-comer and research project based in northern Nevada. HNP participants with CDC Tier 1 findings hereditary breast ovarian cancer syndrome (HBOC), Lynch (LS), or familial hypercholesterolemia (FH) are notified provided counseling. However, subsequently takes a "hands-off" approach: it responsibility to share their healthcare providers, providers...
In this research, we examine and identify the implications of Adverse Childhood Experiences (ACEs) on a range health outcomes, with particular focus number mental disorders.
