Six Months to a Sexy New Body
by Paul Statt in Paul Statt Communications
Public transportation, like, say, public health or the public library, just isn’t sexy. But a fat slob isn’t sexy, either, is he? And with public transportation, he could build a sexy new physique in only 6 to 8 months, according to a recent publication in the the American Journal of Preventive Medicine.... Read more »

Diabetes drug may protect against cancer
by Sally Church in Pharma Strategy Blog
Yesterday, I covered some of the key pathways and kinases associated with cell energy metabolism, LKB1 and AMPK. These, together with Insulin-like Growth Factor-I (IGF-I) and the insulin receptor (IR), appear to play important roles in the broader regulation of...... Read more »

Briefings in Bioinformatics – our education paper is available now
Back in April I happened to mention that we (OpenHelix) were writing a paper on informal sources of bioinformatics education (in a Friday SNPets item) and we were asked to announce when the paper came out. Well, we got word late last week that the article has been published. The article appears in a special issue of Briefings in Bioinformatics that is devoted to bioinformatics education. I’m not sure if all the articles in the issue are available yet, but it looks like several are in the j........ Read more »

What Hurts Fitness More: 30 Years of Aging or 3 Weeks of Bed Rest?
by Travis Saunders, MSc, CEP in Obesity Panacea
I recently came across a very interesting study published in Circulation in 2001. In it, authors Darren McGuire and colleagues perform the 30-year follow-up on a group of 5 men who had taken part in the Dallas Bed Rest and Training Study (DBRTS). The DBRTS took place in 1966, when all 5 men were healthy 20 year-olds. They were assessed extensively at 3 different time points: baseline, following 3 months of bed rest, and following 8 weeks of physical training. In 1996 these same 5 men were as........ Read more »

Were does Resilience against Depression Reside in the Brain?
by Dr Shock in Dr Shock MD PhD
Resilience is in psychiatry the positive capacity of people to cope with stress and catastrophe. In this post it’s used as having an adaptive system that uses exposure to stress to provide resistance to future negative events.
Stress can lead to depression accompanied by atrophy and loss of neurons in the adult hippocampus in experimental [...]

Another Good Reason to Lose the Fat: Stop Urine Leakage
by Steve Parker, M.D. in Advanced Mediterranean Diet Blog
For overweight and obese women, loss of between five and 10% of body weight significantly reduces urine leakage. According to the research report in last month’s Obstetrics & Gynecology journal, weight loss should be the first approach to urine leakage in overweight and obese women.
The other word for urine leakage is incontinence: an involuntary loss of [...]... Read more »

Barriers to Long-Term Living Kidney Donor Follow-up
by Cristy at Living Donor 101 in Living Donors Are People Too
FYI: OPTN requires indefinite follow-up of all transplant recipients, but surgeons and transplant centers have consistently opposed following up on living donors. Keep that in mind as I give a guided tour of this article. Since 1999, UNOS has required transplant programs to report information about living donors at postoperative discharge, 6months, and 12 months (10). In June 2007, this reporting requirement was extended to 24 months (11).UNOS doesn't require anything; OPTN does. UNOS is simply ........ Read more »

Monkeypox infections on the increase in Africa

The incidence of a smallpox-like disease—caused by the monkeypox virus—has increased 20-fold in the Demoncratic Republic of Congo (DRC) over the past 30 years, according to new research published online in the journal PNAS. The findings suggest that, as smallpox vaccination programmes ceased in the DRC in 1980, people are now immunologically ‘naïve’ to orthopoxviruses [...]... Read more »

Genomic analysis can be powerful – in the right hands
by Rachel Bernstein in Berkeley Science Review Blog
You may have heard about the controversial genetics study connecting a set of 150 genetic markers to “exceptional longevity” (people living past 100). Everybody’s interested in living longer, so it’s not surprising that the work, published by Boston University researchers in July in the journal Science, was covered with much fanfare in many main-stream news outlets (for example, in the NY Times and Scientific American).
