Astronaut Edgar Mitchell Claims Alien Cover-up

Dr. Edgar Mitchell is a veteran of the Apollo 14 mission and he was the sixth man to walk on the Moon. Dr. Mitchell also insists that aliens have visited Earth and that governments are actively covering it up. "I happen to have been privileged enough to be in on the fact that we've been visited on this planet and the UFO phenomena is real," Dr Mitchell said. "It's been well covered up by all our governments for the last 60 years or so, but slowly it's leaked out and some of us have been privileged to have been briefed on some of it. "I've been in military and intelligence circles, who know that beneath the surface of what has been public knowledge, yes - we have been visited. Reading the papers recently, it's been happening quite a bit." Dr Mitchell, who has a Bachelor of Science degree in aeronautical engineering and a Doctor of Science degree in Aeronautics and Astronautics claimed Roswell was real and similar alien visits continue to be investigated. He told the astonished Kerrang! radio host Nick Margerrison: "This is really starting to open up. I think we're headed for real disclosure and some serious organisations are moving in that direction." NASA issued a quick denial. In a statement, a spokesman said: "NASA does not track UFOs. NASA is not involved in any sort of cover up about alien life on this planet or anywhere in the universe. "Dr Mitchell is a great American, but we do not share his opinions on this issue." If Dr. Mitchell is correct about a cover-up than this is exactly the type of denial one would expect NASA to make.

Garlic Boosts Hydrogen Sulfide To Relax Arteries

17.10.2007 08:41 Science - Source: ScienceDaily Headlines

Science Daily — Eating garlic is one of the best ways to lower high blood pressure and protect yourself from cardiovascular disease. A new study from the University of Alabama at Birmingham (UAB) shows this protective effect is closely linked to how much hydrogen sulfide (H2S) is produced from garlic compounds interacting with red blood cells.

The UAB researchers found this interaction triggered red blood cells to release H2S, which then led to the relaxation of blood vessels. Fresh garlic was used at a concentration equal to eating two cloves. The resulting H2S production caused up to 72 percent vessel relaxation in rat arteries.

This relaxation is a first step in lowering blood pressure and gaining the heart-protective effects of garlic, said David Kraus, Ph.D., a UAB associate professor in the Departments of Environmental Health Sciences and Biology and the study’s lead author.

The research team examined molecules in garlic called polysulfides and their ability to liberate H2S within cells. The findings appear in the journal Proceedings of the National Academy of Sciences (PNAS).

“When these garlic compounds are metabolized to H2S in the vascular system, the H2S targets membrane channels and causes smooth muscle cells to relax,” Kraus said. “So a garlic-rich diet has many good effects, and H2S may be the common mediator.”

The findings add to a study by John Elrod and David Lefer, Ph.D., of the Albert Einstein College of Medicine published in PNAS that showed H2S protected hearts from the tissue and cell damage often seen in heart attack patients.

The new study, performed by Gloria Benavides, Ph.D., of UAB’s Department of Environmental Health Sciences, Kraus and others, is the first to show garlic-derived polysulfides in the diet boost bodily H2S production.

H2S is a toxic, flammable gas responsible for the smell of rotten eggs. It’s also produced naturally by the body in small amounts, and as age advances, H2S production dwindles.

Exactly how H2S affords the cardiovascular system so much protection is not entirely clear, but it may involve limiting oxidative damage in cells, Kraus said.

“The role of garlic compounds in preventing platelet aggregation, which can trigger a heart attack or stroke, and in limiting cancer growth and the progression of several diseases is well documented,” he said.

The new findings show H2S may be the mediator for these protective benefits. Future studies are being planned to better understand how much H2S production is needed through garlic or supplements to maximize those benefits.

The research is supported grants from the American Heart Association and the National Institutes of Health.
