Spider Venom for Erectile Dysfunction?

Whoever thought that spider venom could could be the answer for erectile dysfunction, however, emergency room visits in Brazil with victims of spider bites displaying priapism, or unrelenting and painful erections, got doctors thinking.

Some research has led to the isolation of an alternative way to help men attain and sustain an erection.

Viagra, Levitra and other ED drugs on the market work by inhibiting an enzyme called PDE5. To get an erection, a man’s body must release nitric oxide, which relaxes the smooth muscle around the arteries of the penis, allowing for his blood vessels to dilate.

The nitric oxide is a first step in a series of chemical reactions that allow this muscle relaxation to take place. One step in the series is cGMP, a signaling molecule that acts to keep the muscles relaxed. PDE5 degrades cGMP. That’s a good thing for ensuring that erections don’t last forever, but too much PDE5 can mean an erection doesn’t happen at all. By blocking the enzyme, PDE5 inhibitors solve the problem.

The spider toxin works differently. Instead of affecting PDE5, the compound seems to trigger nitric oxide release, acting directly to relax the smooth muscles. Because about 30 percent of patients don’t respond to PDE5 inhibitors, the toxin could provide an alternative to ED treatments currently on the market, Nunes said.

  

Avoid Illness In Your Golden Years By Being Fit In Middle Age

Being fit in middle age may not ad years to your life, however, fitness can help you to avoid chronic illness as you age.

Better quality of life, less time spent treating and healing from illness and time to enjoy your old age are the perks of being in great shape now.

Previous studies have shown that people who are more physically fit have a lower risk of dying early than those who aren’t as in shape, but the current analysis, led by Dr. Jarrett Berry of the University of Texas Southwestern Medical Center, is the first to expose a connection with chronic diseases. Berry and his colleagues compared data on fitness levels of 18,670 healthy men and women in their 40s and 50s to Medicare claims for chronic disease treatments a couple of decades later, when the participants became eligible for coverage after age 65. Each of the volunteers performed a treadmill test, during which the researchers measured the length of time they exercised to exhaustion as an indicator of their fitness. For every one-unit improvement in fitness, measured as metabolic equivalents, the volunteers enjoyed a 20% drop in the incidence of the eight conditions the scientists tracked.

  

New Study Suggests That Belly Fat Is Worse Than Obesity For Your Heart Health

The Body Mass Index (BMI) is generally used to assess overall fitness, however, a new study has found that weight concentrated around the middle can be more harmful than obesity itself.

The waist to hip ratio is proving to be a better predictor of heart disease and other illness than BMI alone.

Participants were divided into six groups based on which of the three BMI groups they fell into, and whether they had a normal or high waist-to-hip ratio. Men whose waist measurement was 90 percent or more of their hip measurement were considered to have a high hip-to-waist ratio. The same was true of women; those with waists that were 85 percent of their hip size were classified as having a high hip-to-waist ratio.

Participants with normal BMI but a high waist-to-hip ratio had the risk of dying of cardiovascular disease, and the highest risk of dying from any causes among the six groups.
The risk of cardiovascular death was 2.75 times higher, and the risk of death from any cause was 2.08 times higher among normal-weight people with “central obesity,” compared with normal-weight people who had a normal waist-to-hip ratio.
“The high risk of death may be related to a higher visceral fat accumulation in this group, which is associated with insulin resistance and other risk factors,” said study researcher Dr. Karine Sahakyan, also of Mayo Clinic.

Men can be highly susceptible to accumulating belly fat and inactivity, poor diet and stress contribute to visceral fat.

Keeping your abs toned and your middle “whittled” is the best way to avoid disease and keep your heart strong.
