Will mice help us find the cure for hair loss?
Tuesday, May 29th, 2007Recent scientific experiments using mice have shown that new hair follicles can be induced to grow in new skin when the wound healing process is altered using a wnt protein. This protein caused mature skin cells to behave like embryonic skin cells and form new hair follicles.
The research into this potential hair loss treatment is in the early stages and it remains to be seen if the new hair follicles stimulated to grow in the balding areas could be made to be resistant to balding.

Laser Hair Therapy - is it really FDA Approved?
Tuesday, May 29th, 2007Laser Hair Therapy - is it really FDA Approved?
Tuesday, May 29th, 2007Recently there has been a great deal of discussion and controversy about the recent FDA approval of low level laser therapy. Some members of our discussion forum feel that the marketers of these low level laser hair loss treatments have been misrepresenting this very limited approval for safety by presenting it as if it were an endorsement of their effectiveness in treating hair loss.
In reality the FDA approval for devices like the Laser Max Hair Comb is not based on any measure of their effectiveness as a hair loss treatment. Rather such laser hair therapy devices have merely been FDA approved recently for being non harmful.
Yet the marketers of these low level laser hair therapies have been cleverly touting their products FDA approval in press releases and their advertisements as if it were now proven to be an effective FDA approved hair loss product like Rogaine or Minoxidil.

Erectile Dysfunction — The Canary In The Mineshaft?
Sunday, May 27th, 2007ENDOTHELIAL DYSFUNCTION AND OXIDATIVE STRESS ASSOCIATED WITH THE METABOLIC SYNDROME CAN BE REVERSED BY A CHRONIC TREATMENT WITH SILDENAFIL (Abstract 686)
Metabolic syndrome is characterized by a number of conditions, including elevated blood pressure, excess body fat around the waist and insulin resistance. Many patients with these conditions also exhibit endothelial dysfunction with increases in oxidative stress and decreases in nitric oxide production - which has been related to erectile dysfunction (ED). Researchers from France explored whether treatment with sildenafil citrate - a common pharmacologic treatment for Erectile Dysfunction - could improve endothelial dysfunction in a rat model.
Researchers administered sildenafil to fructose-fed rats to achieve plasma concentrations known to give efficacy in men and observed endothelial function and oxidative stress in the animals during treatment and one-week after treatment had been stopped. It was observed that chronic sildenafil treatment improved endothelial function and oxidative stress, suggesting that this treatment could be a benefit for cardiovascular indications as well as erectile dysfunction.
ERECTILE DYSFUNCTION AND CORONARY HEART DISEASE (Abstract 864)
Research has shown a connection between erectile dysfunction (ED) and cardiovascular disease (CVD) in men, and has established a need to consider one a precursor to the other. Researchers further evaluated the association of these two conditions and whether the association could be age-related.
A random sample of men from the Olmsted County population was evaluated by questionnaire, and community medical records of the subjects were examined. Logistical regression models examined the associations between ED and CVD. Men with CVD were 4.2 times more likely to have ED than men without heart disease. The results underscore a need to consider sexual function in men with heart disease and CVD in men with ED.
