A genome-wide association study of variants associated with acquisition of Staphylococcus aureus bacteremia in a healthcare setting.
(BMC Infect Dis, 2014-02-13)BACKGROUND: Humans vary in their susceptibility to acquiring Staphylococcus aureus infection, and research suggests that there is a genetic basis for this variability. Several recent genome-wide association studies (GWAS) ... -
A new fully automated approach for aligning and comparing shapes.
(Anatomical record (Hoboken, N.J. : 2007), 2015-01)Three-dimensional geometric morphometric (3DGM) methods for placing landmarks on digitized bones have become increasingly sophisticated in the last 20 years, including greater degrees of automation. One aspect shared by ... -
Association of a peripheral blood metabolic profile with coronary artery disease and risk of subsequent cardiovascular events.
(Circ Cardiovasc Genet, 2010-04)BACKGROUND: Molecular tools may provide insight into cardiovascular risk. We assessed whether metabolites discriminate coronary artery disease (CAD) and predict risk of cardiovascular events. METHODS AND RESULTS: We performed ... -
Caloric restriction alters the metabolic response to a mixed-meal: results from a randomized, controlled trial.
(PLoS One, 2012)OBJECTIVES: To determine if caloric restriction (CR) would cause changes in plasma metabolic intermediates in response to a mixed meal, suggestive of changes in the capacity to adapt fuel oxidation to fuel availability or ... -
Correlations between physical and chemical defences in plants: tradeoffs, syndromes, or just many different ways to skin a herbivorous cat?
(The New phytologist, 2013-04)Most plant species have a range of traits that deter herbivores. However, understanding of how different defences are related to one another is surprisingly weak. Many authors argue that defence traits trade off against ... -
Entrepreneurial Attractiveness: Amazon, Google, and the Search for Innovative Hot Spots
(2018-04-18)Recent economic literature suggests that entrepreneurship in technological fields can spur economic growth, making it a popular topic for city development officials. Yet, this increasingly popular phenomenon is met by many ... -
Exercise-induced changes in metabolic intermediates, hormones, and inflammatory markers associated with improvements in insulin sensitivity.
(Diabetes Care, 2011-01)OBJECTIVE: To understand relationships between exercise training-mediated improvements in insulin sensitivity (S(I)) and changes in circulating concentrations of metabolic intermediates, hormones, and inflammatory mediators. ... -
Hands of early primates.
(American journal of physical anthropology, 2013-12)Questions surrounding the origin and early evolution of primates continue to be the subject of debate. Though anatomy of the skull and inferred dietary shifts are often the focus, detailed studies of postcrania and inferred ... -
Heritability estimates of endophenotypes of long and health life: the Long Life Family Study.
(J Gerontol A Biol Sci Med Sci, 2010-12)BACKGROUND: Identification of gene variants that contribute to exceptional survival may provide critical biologic information that informs optimal health across the life span. METHODS: As part of phenotype development efforts ... -
Identification of Chiari Type I Malformation subtypes using whole genome expression profiles and cranial base morphometrics.
(BMC medical genomics, 2014-06)<h4>Background</h4>Chiari Type I Malformation (CMI) is characterized by herniation of the cerebellar tonsils through the foramen magnum at the base of the skull, resulting in significant neurologic morbidity. As CMI patients ... -
Long range dynamic effects of point-mutations trap a response regulator in an active conformation.
(FEBS letters, 2010-10)When a point-mutation in a protein elicits a functional change, it is most common to assign this change to local structural perturbations. Here we show that point-mutations, distant from an essential highly dynamic kinase ... -
Novel loci and pathways significantly associated with longevity.
(Sci Rep, 2016-02-25)Only two genome-wide significant loci associated with longevity have been identified so far, probably because of insufficient sample sizes of centenarians, whose genomes may harbor genetic variants associated with health ... -
Seasonal variations in air pollution particle-induced inflammatory mediator release and oxidative stress.
(Environmental health perspectives, 2005-08)Health effects associated with particulate matter (PM) show seasonal variations. We hypothesized that these heterogeneous effects may be attributed partly to the differences in the elemental composition of PM. Normal human ... -
Sex, temperament, and family context: how the interaction of early factors differentially predict adolescent alcohol use and are mediated by proximal adolescent factors.
(Psychol Addict Behav, 2011-03)Adolescent alcohol use is common and has serious immediate and long-term ramifications. While concurrent individual and context factors are robustly associated with adolescent alcohol use, the influence of early childhood ... -
Strong Selection at MHC in Mexicans since Admixture.
(PLoS genetics, 2016-02-10)Mexicans are a recent admixture of Amerindians, Europeans, and Africans. We performed local ancestry analysis of Mexican samples from two genome-wide association studies obtained from dbGaP, and discovered that at the MHC ... -
Testosterone secretion varies in a sex- and stage-specific manner: Insights on the regulation of competitive traits from a sex-role reversed species.
(General and comparative endocrinology, 2020-06)Testosterone (T) mediates a variety of traits that function in competition for mates, including territorial aggression, ornaments, armaments, and gametogenesis. The link between T and mating competition has been studied ... -
Tissue-specific genetic control of splicing: implications for the study of complex traits.
(PLoS Biol, 2008-12-23)Numerous genome-wide screens for polymorphisms that influence gene expression have provided key insights into the genetic control of transcription. Despite this work, the relevance of specific polymorphisms to in vivo expression ... -
Use of 16S ribosomal RNA gene analyses to characterize the bacterial signature associated with poor oral health in West Virginia.
(BMC Oral Health, 2011-03-01)BACKGROUND: West Virginia has the worst oral health in the United States, but the reasons for this are unclear. This pilot study explored the etiology of this disparity using culture-independent analyses to identify bacterial ...
