May 14, New Test to Assess Aggressiveness of Prostate Cancer
Anti-aging development from the USA could be a breakthrough in the fight against Prostate Cancer --- A new blood test developed at Johns Hopkins University (Maryland, USA), known as the Prostate Health Index (PHI) is making it easier to detect patients who might ultimately need treatment for prostate cancer*.
Whereas elevated Prostate Specific Antigen (PSA) levels can be a sign that prostate cancer is spreading in men with early cancer, the PSA test does not distinguish between slow-growing and aggressive cancers. As a result, there are suggestions that prostate cancer may be overdiagnosed and overtreated.
The new test measures three forms of PSA, including pro-PSA, a shortened molecule that is missing a few of the amino acids that make up the PSA protein, and suggested to be a highly accurate form of PSA. The team led by Robert W. Veltri studied 71 men who were diagnosed with small, low-grade, and low-stage prostate cancer based on their PSA results. Approximately four years later, 39 had unfavorable biopsy results that signaled a need for treatment.
The PHI test was performed on blood samples, banked at the time of biopsy, from all 71 men. When the researchers combined the biopsy results with the PHI data, they were able to predict 7 in 10 men whose cancer might progress, leading them to conclude that: Measurement of the serum PHI and tissue DNA con tent at the time of diagnosis are able to predict which men will ultimately require treatment for prostate cancer.

May 13, Dance Your Way to Better Balance
Anti-aging development from the USA could be the key to better balance as one ages--- As many dancers will tell you the activity increases coordination, builds strength, helps balance and improves morale as well as being a whole load of fun. New studies confirm that dancing is a great anti-aging tool. A loss of balance and diminished gait are major fall risk factors in older persons; some previous studies suggest that physical activity based on dance may improve balance and gait.
Jean Krampe, from the University of Missouri'sSinclair School of Nursing (Missouri, USA), and colleagues studied 11 seniors who participated in regular dance therapy sessions utilizing The Lebed Method, which includes a combination of low-impact dance steps choreographed to music. The researchers found that: Dance therapy results in positive functional trends, suggesting that further study using dance-based therapy will be useful to decrease fall risks in older persons.

May 4, Olive Oil Dampens Genes Responsible for Inflammation
Anti-aging development from Spain could explain benefits of the Mediterranean (DASH) Diet --- May 4th 2010 - Spanish researchers have identified 98 genes whose inflammatory activity is dampened by the consumption of extra virgin olive oil. These findings bring scientists nearer to understanding the mechanism, which makes the Mediterranean diet beneficial for many conditions Ranging from arthritis to heart disease.
Dr. Francisco Perez-Jimenez, from the University of Cordoba (Spain), and his team studied 20 patients with metabolic problems, half of whom eat breakfasts containing olive oil low in phenolic compounds and the other ten eating foods containing extra virgin live oil which is high in phenolic compounds. These studies showed that the pro-inflammatory activity of the genes was suppressed in the latter group. According to the researchers These results provide at least a partial molecular basis for the reduced risk of cardiovascular disease observed in Mediterranean countries, where virgin olive oil represents the main source of dietary fat.
