Their finding, reported this week in the Proceedings of the National Academy of Sciences: nitric oxide (NO). A workhorse of the blood, the gas helps red blood cells ferry oxygen to tissues and props open tiny vessels to allow freer blood flow. It turns out that within hours of leaving the body, levels of nitric oxide in the blood begin to drop, until, by the time donated blood expires after 42 days, the gas is almost nonexistent. "The reality is that we are giving blood that cannot deliver oxygen properly," says Stamler, lead author of the study. "Many patients...

...cocoa may be just what the doctor ordered. Consuming flavonol, an antioxidant found naturally in cocoa, reduces blood pressure and improves circulation, according to a new study co-authored by Harvard Medical School (HMS) Professor of Radiology Norman K. Hollenberg. Flavonol stimulates the body’s production of nitric oxide, which relaxes blood vessels and leads to a reduction in blood pressure, according to the study released last month. But Hollenberg said most cocoa products on the market forsake high levels of the healthy antioxidant during processing in order to enhance their sweetness. “Flavonols are bitter...
...Jilin Petrochemical Company last month. The 50-year-old facility, built with Soviet technology, is China's showcase chemical complex, alma mater to the country's top chemical engineers. On the afternoon of Nov. 13, pressure built up in a 40-m tower at plant No. 101, where nitric acid and benzene are combined to make nitrobenzene, a highly toxic liquid. Technicians tried to relieve the pressure but failed, and the column exploded, killing five workers and injuring 70 others. Five more explosions followed. The blasts broke windows and produced a massive, orange cloud of smoke...
...Stealth Killer Your report on high blood pressure is a timely and critical message for every person [Dec. 13]. In your article, you remarked on the role that nitric oxide plays in relaxing blood vessels. When I shared the Nobel Prize for Medicine in 1998 for my research on the role of nitric oxide in cardiovascular health, I knew we had only begun to understand the importance of this unique molecule. Nitric oxide is critically important in reducing blood pressure and promoting total cardiovascular health. I am convinced by my ongoing research that reduced levels of nitric oxide production...
