Differential developmental trajectories of magnetic susceptibility in human brain gray and white matter over the lifespan.
(Hum Brain Mapp, 2014-06)
As indicated by several recent studies, magnetic susceptibility of the brain is influenced
mainly by myelin in the white matter and by iron deposits in the deep nuclei. Myelination
and iron deposition in the brain evolve ...
Trade-offs between cancer and other diseases: do they exist and influence longevity?
(Rejuvenation Res, 2010-08)
Relationships between aging, disease risks, and longevity are not yet well understood.
For example, joint increases in cancer risk and total survival observed in many human
populations and some experimental aging studies ...
Institutional review boards' use and understanding of certificates of confidentiality.
(PloS one, 2012-01)
Certificates of Confidentiality, issued by agencies of the U.S. government, are regarded
as an important tool for meeting ethical and legal obligations to safeguard research
participants' privacy and confidentiality. By ...
Hybrid de novo genome assembly and centromere characterization of the gray mouse lemur (Microcebus murinus).
(BMC biology, 2017-11-16)
The de novo assembly of repeat-rich mammalian genomes using only high-throughput short
read sequencing data typically results in highly fragmented genome assemblies that
limit downstream applications. Here, we present an ...
Hydroxycarbamide versus chronic transfusion for maintenance of transcranial doppler flow velocities in children with sickle cell anaemia-TCD With Transfusions Changing to Hydroxyurea (TWiTCH): a multicentre, open-label, phase 3, non-inferiority trial.
(Lancet, 2016-02-13)
BACKGROUND: For children with sickle cell anaemia and high transcranial doppler (TCD)
flow velocities, regular blood transfusions can effectively prevent primary stroke,
but must be continued indefinitely. The efficacy of ...
Safety and efficacy of ledipasvir-sofosbuvir in black patients with hepatitis C virus infection: A retrospective analysis of phase 3 data.
(Hepatology, 2016-02)
UNLABELLED: Black patients chronically infected with genotype 1 hepatitis C virus
(HCV) have historically had lower rates of response to interferon-based treatment
than patients of other races. In the phase 3 ION program, ...
Fear learning circuitry is biased toward generalization of fear associations in posttraumatic stress disorder.
(Transl Psychiatry, 2015-12-15)
Fear conditioning is an established model for investigating posttraumatic stress disorder
(PTSD). However, symptom triggers may vaguely resemble the initial traumatic event,
differing on a variety of sensory and affective ...
Joint eQTL assessment of whole blood and dura mater tissue from individuals with Chiari type I malformation.
(BMC Genomics, 2015-01-22)
BACKGROUND: Expression quantitative trait loci (eQTL) play an important role in the
regulation of gene expression. Gene expression levels and eQTLs are expected to vary
from tissue to tissue, and therefore multi-tissue analyses ...
Cardiorespiratory fitness and cognitive function in midlife: neuroprotection or neuroselection?
(Ann Neurol, 2015-04)
OBJECTIVE: A study was undertaken to determine whether better cognitive functioning
at midlife among more physically fit individuals reflects neuroprotection, by which
fitness protects against age-related cognitive decline, ...
A neural biomarker of psychological vulnerability to future life stress.
(Neuron, 2015-02-04)
We all experience a host of common life stressors such as the death of a family member,
medical illness, and financial uncertainty. While most of us are resilient to such
stressors, continuing to function normally, for a ...
