    Learning and Staying in Shape key to Longer Lifespan, study finds

    October 14, 2017, Categories  Biology/Biotechnology, Health/Medical

    Age-specific and sex-specific effects of the 4 GWS associations in LifeGen and the validated candidate loci. The four GWS and three suggestive replicated loci were analysed for age-specific and sex-specific effects on lifespan. a The variants at APOE and CHRNA3/5 exhibit sexually dimorphic effects on parental mortality, while all other variants exhibit more modest often non-significant sex-specific differences. b The effects of each gene on male and female lifespan were meta-analysed and studied in the cases that died aged between 40 and 75 or after 75. APOE exerts a much greater effect in the older age group, while most of the other genes exhibit the opposite effect. FOXO3 appears neutral, if not positive, in the earlier age group. c Effects on mortality were studied in both age groups for both sexes. APOE has the strongest effect on females aged 75+, CHRNA3/5 acts on males aged 40−75 and all other genes display more ambiguous trends

    Want a Younger Brain? Education and Stair-climbing can significantly Slow down Grey-matter Aging

    In a study recently published in the journal Neurobiology of Aging, researchers led by Jason Steffener, a scientist at Concordia University’s Montreal-based PERFORM Centre, show that the more flights of stairs a person climbs, and the more years of school a person completes, the “younger” their brain physically appears. Brain age decreases by 0.95 years for each year of education, and by 0.58 years for every daily flight of stairs climbed – i.e., the stairs between 2 consecutive floors in a building.

    “There already exist many ‘Take the stairs’ campaigns in office environments and public transportation centres,” says Steffe...

    Exercise Associated With Prevention of Low Back Pain

    January 12, 2016, Categories  Biology/Biotechnology, Health/Medical

    Exercise, alone or in combination with education, may reduce the risk of low back pain, a meta-analysis and review of medical literature suggests. Daniel Steffens, Ph.D., of the University of Sydney, Australia, and coauthors identified 23 published reports (on 21 different randomized clinical trials including 30,850 participants) that met their inclusion criteria.

    Moderate-quality evidence suggests exercise combined with education reduces the risk of an episode of low back pain and low- to very low-quality evidence suggests exercise alone may reduce the risk of both a low back pain episode and the use of sick leave. Other interventions, including education alone, back belts and shoe inserts do not appear to be associated with the prevention of low back pain.

    “Although our review found evi...
