With as many as one in eight Americans suffering from chronic migraines, Dr. Yousef Mohammad, a neurologist and principal investigator of the study at Ohio State's Medical Center, says a new study's results of an electronic device designed to "zap" away migraine pain are promising, given that only 50 to 60 percent of migraine patients respond to traditional migraine drug treatments.
Results of the study, to be presented Friday (6/27) at the annual American Headache Society meeting in Boston, found that the experimental device is safe and effective in eliminating headaches when administered during the onset of the migraine.
NeuraLieve, manufacturer of the device located in Sunnyvale, Ca., provided the funding and equipment for the study. Mohammad serves on the company's board of directors.
Large amounts of ozone, 50% more than predicted by the most recent climate models, are being destroyed in the lower atmosphere over the tropical Atlantic Ocean. This discovery by a team of scientists from the UK's National Centre for Atmospheric Science and Universities of York and Leeds has particular significance because ozone in the lower atmosphere acts as a greenhouse gas and its destruction also leads to the removal of the third most abundant greenhouse gas; methane.
The findings come after analysing the first year of measurements from the new Cape Verde Atmospheric Observatory, recently set up by British, German and Cape Verdean scientists on the island of São Vicente in the tropical Atlantic. Alerted by these Observatory data, the scientists flew a research aircraft up into the atmosphere to make ozone measurements at different heights and more widely across the tropical Atlantic. The results mirrored those made at the Observatory, indicating major ozone loss in this remote area.
There are more men involved in high-profile international business deals than women, and that may be hurting companies, according to the results of a new Tel Aviv University study on the role of gender in management, which found that women may be more skilled at business negotiations than their masculine counterparts.
Dr. Yael Itzhaki, an adjunct lecturer at Tel Aviv University's Faculty of Management, carried out simulations of business negotiations among 554 Israeli and American management students at Ohio State University, in New York City, and in Israel. She is also the founder of Netta, a non-profit organization that promotes the advancement of women in the workplace through its programs and research.
The results of her Ph.D. thesis project indicated that in certain groupings, women offered better terms than men to reach an agreement. And women were good at facilitating interaction between the parties, she says.
Dr. Sarah Hake and her colleagues, George Chuck, Hector Candela-Anton, Nathalie Bolduc, Jihyun Moon, Devin O'Connor, China Lunde, and Beth Thompson, have taken advantage of the information from sequenced grass genomes to study how the reproductive structures of maize are formed. Dr. Hake, of the Plant Gene Expression Center, USDA-ARS, who is the 2007 recipient of the Stephen Hales Prize, will be presenting this work at the opening Awards Symposium of the annual meeting of the American Society of Plant Biologists in Mérida, Mexico, June 27th.
Maize was first domesticated in the highlands of Mexico over 6,000 years ago and is now one of the most important crop plants in the world. It is a member of the grass family, which also hosts the world's other major crops including rice, wheat, barley, sorghum, and sugar cane.
Maize has a rich genetic history, which has resulted in thousands of varieties or landraces. Scientists at CIMMYT, Centro Internacional de Mejoramiento de Maíz y Trigo, the International Maize and Wheat Improvement Center, work to preserve the ancient varieties that represent adaptations to different environmental conditions such as different soils, temperature, altitude, and drought. These traits are expressions of different genes and groups of genes that scientists hope to utilize to keep up with changing climatic conditions and global food supply.
It seems pregnancy may confer some protection against bladder cancer - in mice. Female mice that had never become pregnant had approximately 15 times as much cancer in their bladders as their counterparts that had become pregnant, according to new findings by investigators at the University of Rochester Medical Center.
The researchers led by Jay Reeder, Ph.D., are focusing on a fact that has puzzled doctors and scientists for decades: Why does bladder cancer, the fifth most common malignancy in the nation, affect about three times as many men as women?
Scientists long blamed men's historically higher rates of smoking and greater exposure to dangers in the workplace, but the gap has persisted even as women swelled the workforce and took up smoking in greater numbers.
Researchers at Bonn University and the ETH Zürich have discovered that oregano, with its active ingredient beta-caryophyllin (E-BCP, docks on specific receptor structures in the cell membrane - the so-called cannabinoid-CB2 receptors, and produces a change in cell behavior: for example, it will inhibit the cell´s production of phlogogenic signal substances.
E-BCP is a typical ingredient of many spices and food plants. Hence it is also found in plants such as basil, rosemary, cinnamon, and black pepper. Every day, we consume up to 200 milligrams of this annular molecule.
The researchers administered E-BCP to mice with inflamed paws and in seven out of ten cases there was a subsequent improvement in the symptoms. E-BCP might possibly be of use against disorders such as osteoporosis and arteriosclerosis.
