Scientists have discovered a component in turmeric which may relieve symptoms in some inflammatory bowel disease sufferers.
An international consortium of scientists, including researchers from The University of Queensland (UQ), have probed further into the human genome than ever before.
They have discovered how genes are controlled in mammals, as well as the tiniest genetic element ever found.
Their discoveries will be published in three milestone papers in leading journal Nature Genetics.
Invasive species can disrupt natural and human-made ecosystems, throwing food webs out of balance and damaging the services they provide to people. Now scientists have begun to put a price tag on this damage.
(PHILADELPHIA) An herb recently found to kill pancreatic cancer cells also appears to inhibit development of pancreatic cancer as a result of its anti-inflammatory properties, according to researchers from the Kimmel Cancer Center at Jefferson. The data were presented at the AACR 100th Annual Meeting 2009 in Denver. (Abstract #494)
Researchers have determined the structure of a key genetic mechanism at work in bacteria, including some that are deadly to humans, in an important step toward the design of a new class of antibiotics, according to an accelerated publication that appeared online today as a "paper of the week" in the Journal of Biological Chemistry.
Kupffer cells, resident tissue macrophages that line the liver sinusoids, play a key role in modulating inflammation in a number of experimental models of liver injury. Since Kupffer cells represent only a small portion of the entire liver cell population, greatly outnumbered by the parenchymal cells, Kupffer cell isolation faces major technical obstacles.
A team from the Institute for Research in Immunology and Cancer (IRIC) at Université de Montréal has succeeded in producing a large quantity of laboratory stem cells from a small number of blood stem cells obtained from bone marrow. The multidisciplinary team, directed by Dr. Guy Sauvageau, thus took a giant step towards the development of a revolutionary treatment based on these stem cells.
(CHICAGO) - Gastroenterologists at Rush University Medical Center are studying the safety and efficacy of a new system for delivering chemotherapy for patients with esophageal cancer, a rare, but deadly disease that attacks the throat. The unique drug therapy delivers a highly concentrated dose of chemotherapy injected directly on to the hard-to-reach tumors in the esophagus non-surgically.
Oslo, Norway - April 15, 2009 - The Hong Kong flu pandemic was responsible for more than 700,000 deaths worldwide in the late 1960s, with major disease outbreaks in Europe in the winter of 1969-1970.
In the first demonstration of its kind, researchers at the University of British Columbia have controlled the spin of electrons using a ballistic technique--bouncing electrons through a microscopic channel of precisely constructed, two-dimensional layer of semiconductor.
Ethanol production in Minnesota and Iowa uses far less water overall than similar processes in states where water is less plentiful, a new University of Minnesota study shows.
WEST LAFAYETTE, Ind. - Roundup Ready crops have made weed control much easier for farmers, but a new study shows their reliance on the technology may be weakening the herbicide's ability to control weeds.
ATLANTA--Contrary to common stereotypes, individuals with major mental disorders are more likely to become victims of violent crimes when they are experiencing an increase in symptoms than they are to commit crime, according to a new study by Brent Teasdale, an assistant professor of criminal justice at Georgia State University.
