The Nature Explorers Chiricahua Part 3 of 12

submitted by: thenatureexplorers

Chiricahua is a "Sky Island" region that supports a variety of wildlife, some of which are more commonly thought of as denizens of subtropical habitats in Mexico or Central America. Even in February with snow and temperatures as low as -10°F we still found a cornucopia of nature, turkeys, woodpeckers, centipedes, pines, yuccas, agaves, and more.

biosights: September 2, 2013 - Shrinking microtubules pull the centrosome into place

submitted by: JCB
When a T cell encounters a target antigen-presenting cell, it moves its centrosome to the immunological synapse that connects the two cells. Yi et al. reveal that centrosome repositioning is a biphasic process driven by the dynein-dependent capture and depolymerization of microtubules. This biosights episode presents the paper by Yi et al. from the September 2, 2013, issue of The Journal of Cell Biology and includes an interview with senior author John Hammer (NHLBI, Bethesda, MD).

submitted by: jannique.van.uffelen
Background: Associations of sitting-time and physical activity with depression are unclear. Purpose: To examine concurrent and prospective associations between both sitting-time and physical activity with prevalent depressive symptoms in mid-aged Australian women. Methods: Data were from 8950 women, aged 50–55 years in 2001, who completed mail surveys in 2001, 2004, 2007, and 2010. Depressive symptoms were assessed using the Center for Epidemiological Studies Depression questionnaire....

MWV Episode 76 - Jeffrey Almond - Vaccine Development

submitted by: MicrobeWorld
Dr. Jeffrey Almond began his career as an academic virologist studying influenza. Eventually Jeffrey started his own lab and began studying picornaviruses working on an oral polio vaccine strain. Following twenty years in academics including major contributions in the eradication of polio worldwide, Jeffrey transitioned into a career in industry working on vaccine development at Sanofi Pasteur. In March of 2013, Jeffrey was at the Society for General Microbiology's Spring conference to...

A diet rich in high glucoraphanin broccoli interacts with genotype to reduce discordance in plasma metabolite profiles through modulating mitochondrial function

submitted by: Andrew Chapple
Background: Observational and experimental studies suggest that diets rich in cruciferous vegetables and glucosinolates may reduce the risk of cancer and cardiovascular disease (CVD). Objective: We tested the hypothesis that a 12-wk dietary intervention with high-glucoraphanin (HG) broccoli would modify biomarkers of CVD risk and plasma metabolite profiles to a greater extent than interventions with standard broccoli or peas. Design: Subjects were randomly assigned to consume 400 g...
