A new study reports what scientists term the first scientific evidence that freshly crushed garlic has more potent heart-healthy effects than dried garlic. Scheduled for the Aug. 12 issue of the Journal of Agricultural and Food Chemistry, it also challenges the widespread belief that most of garlic's benefits are due to its rich array of antioxidants. Instead, garlic's heart-healthy effects seem to result mainly from hydrogen sulfide, a chemical signaling substance that forms after garlic is...

University of Leicester researcher probes role of hydrogen sulphide Scientists at the University of Leicester are investigating how the stuff of stink bombs and flatulence could play a critical role in the human reproductive system. Hydrogen sulphide "“partially responsible for the foul odor of stink bombs- is also a toxic gas and has been used for chemical warfare. But research at the University of Leicester is now looking at beneficial effects it has in the body- and the potentially...

CHAMPLAIN, N.Y., July 17 /PRNewswire/ -- Electrocorp, an industrial air purification company, is receiving national attention after field testing by a Florida company showed levels of Hydrogen Sulfide (H2S) and other gases, emitted from tainted Chinese drywall that was used to build hundreds of thousands of homes across North America, were reduced by 80% to 90% after only 24 hours of operating Electrocorp's air purification equipment. "We expected great results from these units," said...

PITTSBURGH, May 28 /PRNewswire/ -- Draeger is expanding its family of single gas detectors with the launch of the Draeger Pac 3500 and Draeger Pac 5500. Designed for personal protection, these gas detectors measure the concentration of oxygen, carbon monoxide or hydrogen sulfide in the air. The Draeger Pac 3500 has a lifespan of approximately two years and the Draeger Pac 5500 has an indefinite lifespan with proper maintenance and servicing. Both instruments use minimal battery power and need...

Sedimentary rocks created more than 2.4 billion years ago sometimes have an unusual sulfur isotope composition thought to be caused by the action of ultra violet light on volcanically produced sulfur dioxide in an oxygen poor atmosphere. Now a team of geochemists can show an alternative origin for this isotopic composition that may point to an early, oxygen-rich atmosphere."The significance of this finding is that an abnormal isotope fractionation (of sulfur) may not be linked to the...

U.S. and Italian researchers say hydrogen sulfide emitted by hot springs may act as a natural version of Viagra. The gas, which has a pungent odor often compared to the smell of rotten eggs, has been found to widen blood vessels and appears to be able to combat impotence, the Italian news service ANSA reported. The research was conducted under the guidance of researchers at Naples University and Nobel prize-winning pharmacologist Louis Ignarro of the University of California at Los Angeles....

It stinks and strikes fear in the hearts of those who work underground, but the toxic gas hydrogen sulfide may be a lifesaver for patients with heart failure. In a recent study, low concentrations of hydrogen sulfide gas improved functioning in the hearts of mice with heart failure. After heart failure was induced in mice, the gas was administered intravenously once a day for a week. Four weeks after the heart failure event, mice treated with hydrogen sulfide had about a one-third higher...

US researchers say the gas best known for being used in many stink bombs may also control blood pressure. The foul odor of flatulence is due to small amounts of hydrogen sulphide - a toxic gas generated by bacteria living in the human gut. But researchers say the gas is also produced by an enzyme in blood vessels that relaxes them and lowers blood pressure. The Science journal reported that the findings in mice might lead to new treatments for high blood pressure. The gas is produced in the...

By Schiffman, Susan S Graham, Brevick G; Williams, C Mike ABSTRACT The effectiveness of 18 alternative technologies for reducing odor dispersion at and beyond the boundary of swine facilities was assessed in conjunction with an initiative sponsored through agreements between the Attorney General of North Carolina and Smithfield Foods, Premium Standard Farms, and Frontline Farmers. The trajectory and spatial distribution of odor emitted at each facility were modeled at 200 and 400 m downwind...

Sulfur (or Sulphur; see spelling below) is the chemical element in the periodic table that has the symbol S and atomic number 16. It is an abundant, tasteless, odorless, multivalent non-metal. Sulfur, in its native form, is a yellow crystaline solid. In nature, it can be found as the pure element or as sulfide and sulfate minerals. It is an essential element for life and is found in several amino acids. Its commercial uses are primarily in fertilizers but it is also widely used in gunpowder,...
