BACKGROUND: Anxiety produced by environmental threats can impair goal-directed processing
and is associated with a range of psychiatric disorders, particularly when aversive
events occur unpredictably. The prefrontal cortex ...
Mindfulness training for smokers via web-based video instruction with phone support: a prospective observational study.
(BMC complementary and alternative medicine, 2015-03-29)
BACKGROUND:Many smokers are unable to access effective behavioral smoking cessation
therapies due to location, financial limitations, schedule, transportation issues
or other reasons. We report results from a prospective ...

Polymorphisms in Fibronectin Binding Proteins A and B among Staphylococcus aureus Bloodstream Isolates Are Not Associated with Arthroplasty Infection.
(PLoS One, 2015)
BACKGROUND: Nonsynonymous single nucleotide polymorphisms (SNPs) in fibronectin binding
protein A (fnbA) of Staphylococcus aureus are associated with cardiac device infections.
However, the role of fnbA SNPs in S. aureus ...
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, ...

Associations of PI3KR1 and mTOR polymorphisms with esophageal squamous cell carcinoma risk and gene-environment interactions in Eastern Chinese populations.
(Scientific reports, 2015-01)
Single nucleotide polymorphisms (SNPs) in the PI3K/PTEN/AKT/mTOR signaling pathway
may contribute to carcinogenesis. We genotyped five potentially functional PIK3R1
and mTOR SNPs in 1116 esophageal squamous cell cancer (ESCC) ...
