Whole genome sequences of a male and female supercentenarian, ages greater than 114 years
(2011)Supercentenarians (age 110+ years old) generally delay or escape age-related diseases and disability well beyond the age of 100 and this exceptional survival is likely to be influenced by a genetic predisposition that ... -
Design of the WHIP-PD study: a phase II, twelve-month, dual-site, randomized controlled trial evaluating the effects of a cognitive-behavioral approach for promoting enhanced walking activity using mobile health technology in people with Parkinson-disease
(2020-04-20)BACKGROUND: Parkinson disease (PD) is a debilitating and chronic neurodegenerative disease resulting in ambulation difficulties. Natural walking activity often declines early in disease progression despite the relative ... -
Long-term yogurt consumption and risk of incident hypertension in adults
(LIPPINCOTT WILLIAMS & WILKINS, 2018-08-01) -
Concussion, microvascular injury, and early tauopathy in young athletes after impact head injury and an impact concussion mouse model
(OXFORD UNIV PRESS, 2018-02-01)The mechanisms underpinning concussion, traumatic brain injury, and chronic traumatic encephalopathy, and the relationships between these disorders, are poorly understood. We examined post-mortem brains from teenage athletes ... -
A Three-Stage Approach for Genome-Wide Association Studies with Family Data for Quantitative Traits
(BioMed Central, 2010-5-14)BACKGROUND. Genome-wide association (GWA) studies that use population-based association approaches may identify spurious associations in the presence of population admixture. In this paper, we propose a novel three-stage ... -
Genome-wide association studies of serum magnesium, potassium, and sodium concentrations identify six loci influencing serum magnesium levels
(Public Library of Science, 2010-8-5)Magnesium, potassium, and sodium, cations commonly measured in serum, are involved in many physiological processes including energy metabolism, nerve and muscle function, signal transduction, and fluid and blood pressure ... -
Automated MRI Measures Identify Individuals with Mild Cognitive Impairment and Alzheimer's Disease*
(Oxford University Press, 2009-5-21)Mild cognitive impairment can represent a transitional state between normal ageing and Alzheimer's disease. Non-invasive diagnostic methods are needed to identify mild cognitive impairment individuals for early therapeutic ... -
Genetic Analysis Workshop 15: Gene Expression Analysis and Approaches to Detecting Multiple Functional Loci
(BioMed Central, 2007-12-18) -
Joint Modeling of Linkage and Association Using Affected Sib-Pair Data
(BioMed Central, 2007-12-18)There has been a growing interest in developing strategies for identifying single-nucleotide polymorphisms (SNPs) that explain a linkage signal by joint modeling of linkage and association. We compare several existing ... -
Comparisons of Case-Selection Approaches Based on Allele Sharing and/or Disease Severity Index: Application to the GAW14 Simulated Data
(BioMed Central, 2005-12-30)For mapping complex disease traits, linkage studies are often followed by a case-control association strategy in order to identify disease-associated genes/single-nucleotide polymorphisms (SNPs). Substantial efforts are ...
