Are we closing in on a female viagra?

Posted by admin | No Comments

Canadian Viagra, the equivalent for men, was approved for sale back in 1998 by the FDA but the scientific world has been lagging when it comes to a similar medication for women. With approximately 40 percent of women not able to achieve orgasm at some point in their life, there certainly would seem to be a market for such a prescription medication.

“Medical giant Company” has been working on the development of a drug that will boost female sexual arousal and increase the chance of orgasm, technically called female sexual arousal disorder (FSAD). While it is still in development, testing of a prototype has begun on animal subjects. The most recent study was conducted by a team of British researchers on rabbits.

The experiment involved stimulating arousal in the bunnies and then injecting them with the drug. The results show that the drug blocks an enzyme that checks blood flow to the arousal region, allowing for a greater blood flow and increased arousal in the rabbits.

When a woman becomes sexually aroused, emotional and physical cues in the brain tell the body to increase blood flow to the genitals; this relaxes the vagina, improves lubrication and increases sensation,” said lead researcher Chris Wayman.

Not meant to initiate desire, the drug is intended to boost the flow of blood during a situation where arousal has already occurred, allowing for a greater chance of orgasm.

“Medical giant Company” still has much development work to do to come up with a workable drug, and years of drug trials will no doubt keep a female Viagra out of the market for the foreseeable future.

Monticello Dam

Posted by admin | No Comments

Monticello Dam is a dam in Napa County, California, United States constructed between 1953 and 1957. It is a medium concrete-arch dam with a structural height of 304 ft (93 m) and a crest length of 1,023 ft (312 m). It contains 326,000 cubic yards (249,000 m³) of concrete. The dam impounded Putah Creek to cover the former town of Monticello and flood Berryessa Valley to create Lake Berryessa, the second-largest lake in California. The capacity of the reservoir is 1,602,000 acre·ft (1,976,000 dam³). Water from the reservoir is supplied mostly to the North Bay area of San Francisco.

The dam is noted for its classic, uncontrolled spillway with a rate of 48,400 cubic feet per second (1370 m³/s) and a diameter at the lip of 87 ft (27 m).
