Results of the study are published in the November issue of Catheterization and Cardiovascular Intervention, a peer-reviewed journal from The Society for Cardiovascular Angiography and Interventions. Percutaneous ...

Two essential genes that control the accumulation and detoxification of arsenic in plant cells have been identified. This discovery is the fruit of an international collaboration involving laboratories in Switzerland, South Korea and the United States, with the participation of members of the National Centre of Competence in Research (NCCR) Plant Survival. The results presented are a promising basis for reducing the accumulation of arsenic in crops from regions in Asia that are polluted by this toxic metalloid, as well as for the cleanup of soils contaminated by heavy metals. ...

Scientists are learning more about how protein gets in the urine when the kidneys begin to fail and how a new drug blocks it. "We have known for a long time that renal failure comes with protein in your urine, especially in diabetes," said Dr. David Pollock, renal physiologist at the Medical College of Georgia Vascular Biology Center. It's also known that a new class of drugs called endothelin A receptor antagonists reduce protein in the urine. New research published in the journal Hypertension connects the two, providing more information about how new drugs under study ...

WASHINGTON — The United States is missing significant opportunities to reduce traffic fatalities and injuries, and could save lives by implementing a more rigorous, comprehensive program that adopts successful safety practices from other countries, says a new report by the National Research Council. The committee that wrote the report reviewed traffic safety practices and strategies in high-income countries around the world and compared them with those in the United States. From 1995 to 2009, fatalities dropped 52 percent in France, 38 percent in the United Kingdom, ...

Montreal, November 16, 2010 – Disadvantaged kids are more likely to drop out of high school, become premature parents and raise their own children in poverty, according to an exhaustive new study from researchers at Concordia University and the University of Ottawa. Published in the International Journal of Behavioral Development, the investigation was the first to follow boys and girls over three decades to examine whether childhood aggression, social withdrawal and low socio-economic status could impact adult wellbeing. "Low socioeconomic status appears to have ...

A new study from the Swedish medical university Karolinska Institutet shows that asthma drugs are a potential treatment for aortic aneurysm. These drugs, which block cysteinyl-leukotrienes, could reduce the break down of vessel wall tissue and the dilation of the aortic wall, and thus the risk of its rupturing. This could both save lives and reduce the need for complicated and risky surgery. The results are presented in the scientific journal PNAS. Aortic aneurism is a life-threatening disease caused by the weakening of a section of the wall of the aorta, which then ...

HealthSpace, the internet-accessible personal health organiser developed as part of the National Programme for IT in the National Health Service, was significantly less popular than anticipated, a research team from the University of London has found. Instead of the predicted 5-10% of the population signing up, only 0.13% of those invited got as far as activating the full functionality of their personal health record, according to the study published on bmj.com today. Professor Trisha Greenhalgh from Barts and the London School of Medicine and Dentistry led the team ...

An open letter from 20 consultants and a patient group published on bmj.com today, calls on the prime minister to take action over a legal loophole that allows drug companies to make easy profits by licensing existing treatments for rare (orphan) diseases. They argue that the current situation concerning orphan drugs is not in the best interests of patients or the NHS and that the cost to the NHS is likely to be above £10m a year. The original purpose of this legislation was to encourage drug companies to conduct research into rare diseases and develop new treatments. ...

This is the conclusion of a study led by researchers from the Institute of Environmental Assessment and Water Research (IDAEA-CSIC), published this week in the Journal of Hazardous Materials. "The toxicological research has shown that many of the metallic particles in the smoke from fireworks are bio-reactive and can affect human health", Teresa Moreno, a researcher from the IDAEA (CSIC) and lead author of a study that has been published this week ...

ANN ARBOR, Mich. -- University of Michigan researchers have solved the structure of a protein that is integral to processes responsible for maintaining a healthy heart and nervous system. The protein structure in question is cystathionine beta-synthase, known as CBS. CBS uses vitamin B6 to make hydrogen sulfide (H2S), a gaseous signaling molecule that helps maintain a healthy heart and nervous system. H2S also induces a state of suspended animation or hibernation in animals by decreasing body temperature and lowering metabolic rate. The work to decode the structure ...

Arlington, Va. — New research being presented at the 2010 International Pharmaceutical Federation (FIP) Pharmaceutical Sciences World Congress (PSWC) in association with the American Association of Pharmaceutical Scientists (AAPS) Annual Meeting and Exposition will feature an inhalable dry powder antibiotic that when used alone or with current treatments may significantly reduce treatment for tuberculosis (TB) and multi-drug resistant TB.

Whether a small cut with a fruit knife, a surgical wound or a major injury caused by a fall – the body's defense and repair system leaps into action and tries to close the wound as quickly as possible. Small injuries usually heal within a few days, but a gaping wound will take longer to heal, and an infection can take hold even after several days. Dressings protect the site of the injury but to check the wound they have to be removed. This can be painful for the patient and moreover it risks giving germs the chance to enter and cause infection. Scientists at the Fraunhofer ...

Hair clippings, cayenne pepper and raw eggs – these are just a few of the odd ingredients recommended to keep those pesky deer away from your backyard garden. But what about farmers who have hundreds of acres of Christmas trees to protect? North Carolina State University extension specialists have now found an effective, inexpensive alternative to available commercial products to keep the deer at bay. The NC State researchers, led by Jeff Owen, a Christmas-tree production specialist, are exploring the use of inexpensive, inedible food byproducts – such as dried blood ...

WEST LAFAYETTE, Ind. - Researchers have demonstrated a new imaging tool for rapidly screening structures called single-wall carbon nanotubes, possibly hastening their use in creating a new class of computers and electronics that are faster and consume less power than today's. The semiconducting nanostructures might be used to revolutionize electronics by replacing conventional silicon components and circuits. However, one obstacle in their application is that metallic versions form unavoidably during the manufacturing process, contaminating the semiconducting nanotubes. Now ...

WEST LAFAYETTE, Ind. - Researchers at Purdue University are studying the effects of fire on steel structures, such as buildings and bridges, using a one-of-a-kind heating system and a specialized laboratory for testing large beams and other components. Building fires may reach temperatures of 1,000 degrees Celsius, or more than 1,800 degrees Fahrenheit, said Amit Varma, a Purdue associate professor of civil engineering who is leading the work.g1 "At that temperature, exposed steel would take about 25 minutes to lose about 60 percent of its strength and stiffness," he ...

PITTSBURGH—A computer algorithm developed at Carnegie Mellon University matched living kidney donors with medically compatible transplant candidates late last month as the national Organ Procurement and Transplantation Network (OPTN), operated by the United Network for Organ Sharing (UNOS), began a national pilot program to increase the number of kidney paired-donation (KPD) transplants. The initial run of the computer matching process included just 43 kidney transplant candidates and 45 potential living donors, but a national KPD pool eventually could include as many ...

By examining the distinct wave patterns formed from complex biochemical reactions within the human body, diseased organs may be more effectively identified, says Zhengdong Cheng, associate professor in the Artie McFerrin Department of Chemical Engineering at Texas A&M University, who has developed a model that simulates how these wave patterns are generated. His findings, which appear in the October issue of the journal "Physical Review E," detail Cheng's work with a system designed to model cells in a biochemical environment, similar to what occurs inside the human body. His ...

CHAMPAIGN, Ill. — According to a popular hypothesis, grasses such as maize, sugar cane, millet and sorghum got their evolutionary start as a result of a steep drop in atmospheric carbon dioxide levels during the Oligocene epoch, more than 23 million years ago. A new study overturns that hypothesis, presenting the first geological evidence that the ancestors of these and other C4 grasses emerged millions of years earlier than previously established. The findings are published in the journal Geology. C4 plants are more efficient than C3 plants at taking up atmospheric ...

Two new studies have shown that a unique program in East Harlem that helps middle school students learn practical health skills and gain a better understanding of medical conditions, such as diabetes and hypertension, resulted in increased interest in college attendance and medical careers among the students who attended the program. The results were presented at the American Public Health Association (APHA) Annual Meeting this month in Denver. The MedStart Summer Enrichment Program was created in the summer of 2009 by Edward Chu and Melissa Schneiderman, two third-year ...
