Medical Industry Showers DOD With Free Travel
The health care industry funded "8,700 trips by Department of Defense personnel" from 1998 to 2007, at a cost of more than $10 million, the Center for Public Integrity reports. "In a joint project with Northwestern University"s Medill School of Journalism, the Center examined 22,000 travel disclosure forms filed by DOD personnel, and found that the medical industry was by far the biggest sponsor of free travel, accounting for about 40 percent of all trips. The sponsors included not only drug and device makers but also health foundations and trade groups often funded by those companies."

Health Benefits Tax Gains Support In Congress, Opponents In Business
"You can think of Congress"s efforts to pay for health reform as being a little bit like a battle to slay a many-headed Hydra," writes the New York Times" economic columnist, David Leonhardt. Congress has floated idea after idea for paying for comprehensive health reform, but their proposals have failed to make ends meet because they "do not raise revenue as quickly as health costs rise." Most new taxes - such as a surtax on the rich proposed in the House - increase only as quickly as the economy, while health costs have inflated much more quickly over the last decade.

Zinc Levels In Seminal Plasma Are Associated With Sperm Quality In Fertile And Infertile Men

UroToday.com - Insufficient intake of zinc (Zn) can impair antioxidant defenses and may be an important risk factor in oxidant release, compromising the mechanism of DNA repair, and making the sperm cell highly susceptible to oxidative damage. In the absence of Zn, the possibility of increased oxidative damage exists that would contribute to poor sperm quality. Infertile men and men who smoke are very susceptible to oxidative damage induced by free radicals. In the present study, we hypothesized that major changes in the level of seminal Zn levels are related with low quality of sperm and poor fertilizing capacity. Semen samples were collected from fertile (smoker [n = 17], nonsmoker [n = 19]) and infertile men (smoker [n = 15], nonsmoker [n = 21]). After collection, semen specimens were allowed to liquefy at room temperature for 30 minutes and used for parameters analysis. On microscopic examination, sperm count, percentage of motile sperm, and sperm with normal morphology were objectively evaluated. Semen samples were centrifuged at 600g for 10 minutes. After centrifugation, supernatants were diluted 10-fold by deionized water. Levels of Zn were measured by atomic absorption spectroscopy (AAS). Fertile groups (smokers or nonsmokers) demonstrated significantly higher Zn levels in their seminal plasma than any infertile groups (pUroToday - the only urology website with original content written by global urology key opinion leaders actively engaged in clinical practice.
