Social Media Delivered Sexual Health Intervention: A Cluster Randomized Controlled Trial

submitted by: sheana
Design: Cluster randomized trial; data collected in 2010-2011; analyzed in 2011-2012 Setting/Participants: Individuals (seeds) recruited in multiple settings (online, via newspaper ads and face-to-face) who were asked to recruit up to three friends, who in turn recruited additional friends, extending three waves from the seed. Seeds and waves of friends were considered networks and exposed to either intervention or control condition. Intervention: Exposure to Just/Us, a Facebook page...

Science Nation - If These Teeth Could Talk

submitted by: nsf
With funding from the National Science Foundation, Peter Ungar is revealing more details about the lives of our human ancestors, and he's doing it through dentistry - sort of! The University of Arkansas anthropologist uses high tech dental scans to find out more about the diets of hominids, a technique that sometimes leads to new and very different conclusions. While anthropologists traditionally determine the diets of our ancestors by examining the size and shape of teeth and jaws, Ungar's...

Nonpungent capsaicin analogs (capsinoids) increase energy expenditure

submitted by: Yoneshiro
Background: Capsinoids—nonpungent capsaicin analogs—are known to activate brown adipose tissue (BAT) thermogenesis and whole-body energy expenditure (EE) in small rodents. BAT activity can be assessed by [18F]fluorodeoxyglucose–positron emission tomography (FDG-PET) in humans. Objectives: The aims of the current study were to examine the acute effects of capsinoid ingestion on EE and to analyze its relation to BAT activity in humans. Design: Eighteen healthy men aged 20–32 y...

Correcting for Inflammation Changes Estimates of Iron Deficiency among Rural Kenyan Preschool Children

submitted by: ebogrant5
The assessment of iron status where infections are common is complicated by the effects of inflammation on iron indicators and in this study we compared approaches that adjust for this influence. Blood was collected in 680 children (aged 6–35 mo) and indicators of iron status [(hemoglobin (Hb), zinc protoporphyrin (ZP), ferritin, transferrin receptor (TfR), and TfR/ferritin index)] and subclinical inflammation [(the acute phase proteins (APP) C-reactive protein (CRP), and a-1-acid...

Demo: Variation for the ZAP70 gene with Ensembl

submitted by: gspudich

We use the Ensembl genome browser at www.ensembl.org to view small scale sequence variants such as SNPs (single nucleotide polymorphims) along with larger structural variations like CNVs (copy number variation) for the human ZAP70 gene.

Cellular and Functional Optical Coherence Tomography of the Human Retina (The Cogan Lecture)

submitted by: arvojenny
An imaging modality that allows for fast, simultaneous, noninvasive probing of both three-dimensional (3D) cellular resolution retinal morphology and depth-resolved function could substantially improve the early diagnosis of various retinal diseases that are the leading causes of blindness worldwide and could contribute to a better understanding of retinal pathogenesis and enhanced therapy monitoring. In addition to user friendliness, reliability, and cost, the key technological parameters...

Acute Ingestion of Long-Chain (n-3) Polyunsaturated Fatty Acids Decreases Fibrinolysis in Men with Metabolic Syndrome

submitted by: lrobinson
Individuals with metabolic syndrome (MetS) often have elevated plasma plasminogen activator inhibitor-1 (PAI-1) and tissue plasminogen activator (t-PA), contributing to an increased risk of cardiovascular disease. PAI-1 and t-PA may be affected by chronic (n-3) long-chain PUFA [(n-3)LCPUFA] supplementation; however, the acute impact of fat ingestion on these risk factors has not been established. Our objective was to investigate the acute effect of (n-3)LCPUFA on plasma PAI-1, t-PA, and...
