Gotta Love That Genome

Cool news for your Monday – Researchers from Duke University have discovered a way to examine the entire genome and find the “unpackaged” centers that direct gene expression:
A new resource that identifies regions of the human genome that regulate gene expression may help scientists learn about and develop treatments for a number of human diseases, according to researchers at Duke’s Institute for Genome Sciences & Policy (IGSP). … “Scientists have used similar methods to look at tiny portions of the genome in the past, but ours is the first technology to really allow researchers to look at the whole genome, so we can see all of the areas where gene regulation occurs,” said Terrence Furey, Ph.D., a researcher in the IGSP and co-senior investigator on this study. “Identifying these sites may help us understand the biological basis for gene regulation expression patterns in different cell types. We’ll also compare patterns within and across species, in response to external stimuli and in diseased tissues.”

Dear Mark: Sugar Cravings

Dear Mark,

I do pretty well in the fitness department, love my veggies and get plenty of protein. My problem is that I can’t seem to shake my sugar cravings. Suggestions?

I get some version of this question on a fairly regular basis. A common theory says that we evolved to crave sweet tastes in order to seek out healthy fruits to diversify our diets. The problem comes in the current age when our inclination is bombarded with the likes of Coco Puffs, Snickers and pudding packs.

Anaerobic Exercise HGH Link

I love this stuff. A recent study published in the British Journal of Sports Medicine may help explain what I have been saying for quite some time here: that exercise stimulates the natural production of growth hormone (the very same HGH we just wrote about yesterday). But it’s the type of exercise that makes all the difference. And this further confirms something else we’ve been saying: that it’s short intense bursts that work the best.

Study Finds Exercise Prolongs Lifespan

A study published Tuesday in the online edition of the American Heart Association’s journal Circulation suggests that frequent exercise can reduce the risk of death in men.

To examine the link between fitness and mortality, Veterans Affairs (VA) researchers gathered fitness data on 15,660 male VA patients undergoing treadmill testing for various medical reasons. The men, who had an average age of 60, where then assigned to one of four groups based on their level of fitness.

According to the results, mortality risk directly correlated with fitness level, with men in the highest fitness category being the least likely to die when compared to their less fit counterparts. For example, across the eight year study period, 44% of the men in the least fit group died, compared to 30% in the moderately fit group, 15% in the highly fit group, and 8% in the very highly fit group.

The Hype Over Human Growth Hormone

A lot of questions hit the MDA doorstep about HGH, Human Growth Hormone, and with good reason. It’s been touted in some circles as a bottled fountain of youth among other grandiose claims. Countless companies have jumped on that bandwagon, peddling worthless products with HGH labels.

We love to take on the propagandists and snake oil sales industries, and today will be no exception. Shall we begin?

The Basics of HGH
The natural HGH coursing through your body right now is, indeed, a perfectly remarkable anabolic hormone. It’s produced by the pituitary gland throughout life, but the levels gradually decline with age. The hormone is key for children’s growth and the health of the body’s organs. It stimulates the growth of muscle, bone and cartilage and enhances immune function. HGH is prescribed for children who are abnormally short in stature and for adults with diagnosed pituitary deficiency.
