PHILADELPHIA - The lab of Kevin Foskett, PhD, the Isaac Ott Professor of Physiology at the University of Pennsylvania School of Medicine, has found a possible new target for fighting cystic fibrosis (CF) that could compensate for the lack of a functioning ion channel in affected CF-related cells. Their finding appears in the Journal of Clinical Investigation.
Global efforts to tackle millions of preventable child and maternal deaths will fail to extend gains unless world leaders act now to pour more healthcare resources directly into families and communities, according to a new World Vision report launched today.
HOUSTON -- (Sept. 17, 2010) -- An examination of a portion of the tuberculosis genome that responds to stress has allowed Rice University bioengineers Oleg Igoshin and Abhinav Tiwari to zero in on a network of genes that may "switch" the disease into dormancy.
New Rochelle, NY, September 17, 2010—September is National Childhood Obesity Awareness Month, drawing attention to the epidemic of obesity among children and adolescents in the United States. A multidisciplinary approach to assessment and intervention is crucial for effective weight management and should draw from the latest medical evidence, best practices, and innovative educational and policy initiatives, all of which are presented and debated in the new bimonthly, print and online journal Childhood Obesity, published by Mary Ann Liebert, Inc.
PHILADELPHIA – On average, one hundred billion cells in the human body divide over the course of a day. Most of the time the body gets it right but sometimes, problems in cell replication can lead to abnormalities in chromosomes resulting in many types of disorders, from cancer to Down Syndrome.
Terrorist networks are complex. Now, a mathematical analysis of their properties published this month in the International Journal of Networking and Virtual Organisations, suggests that the best way to fight them is to isolate the hubs within the network rather than trying to destroy the network as a whole through short-term battles.
LIVERPOOL, UK – 17 September 2010: Research at the University of Liverpool could lead to faster and more accurate diagnoses of liver damage.
The team used paracetamol as the basis for the study: research indicates that paracetamol can place temporary stress on the liver in around a third of people who take a normal dose (4g per day) but the liver returns to normal when the drug has left the system. Overdoses of the drug are a major cause of liver failure in both the UK and US.
MANHATTAN, KAN. -- While natural food is a rising trend among humans, pet owners should be careful before feeding similar types of food to their pets, according to a Kansas State University veterinarian.
All too often pet owners assume that because certain foods, such as fruits and vegetables, are healthy for them, they are also healthy for their pets, said Susan Nelson, K-State assistant professor of clinical services.
"Natural and veggie-based pet foods are based more on market demand from owners, not because they are necessarily better for the pet," she said.
In 2008, Reuben Granich and his colleagues at the World Health Organization published a paper in the medical journal The Lancet that proposed a new strategy for combating HIV in South Africa, a country staggered by the virus, with as much as 18 percent of the population estimated to be infected.
UCLA physicists have taken a significant step in controlling chemical reactions mechanically, an important advance in nanotechnology, UCLA physics professor Giovanni Zocchi and colleagues report.
Chemical reactions in the cell are catalyzed by enzymes, which are protein molecules that speed up reactions. Each protein catalyzes a specific reaction. In a chemical reaction, two molecules collide and exchange atoms; the enzyme is the third party, the "midwife to the reaction."
The sequencing and analysis of the genome for the Criollo variety of the cacao tree, generally considered to produce the world's finest chocolate, was completed by an international team led by Claire Lanaud of CIRAD, France, with Mark Guiltinan of Penn State, and included scientists from 18 other institutions.
"The large amount of information generated by this project dramatically changes the status of this tropical plant and its potential interest for the scientific community," said Guiltinan, professor of plant molecular biology, Penn State.
Berkeley — Girls in homes without a biological father are more likely to hit puberty at an earlier age, according to a new study led by researchers at the University of California, Berkeley's School of Public Health.
The findings, to be published Sept. 17 in the Journal of Adolescent Health, found that the absence of a biologically related father in the home predicted earlier breast and pubic hair development, but only for girls in higher income households. The findings held even after the girls' weight was taken into account.
Two popular supplements taken by millions of people around the world to combat joint pain, do not work, finds research published on today.
The supplements, glucosamine and chondroitin, are either taken on their own or in combination to reduce the pain caused by osteoarthritis in hips and knees.
The researchers, led by Professor Peter Jüni at the University of Bern in Switzerland, argue that given these supplements are not dangerous "we see no harm in having patients continue these preparations as long as they perceive a benefit and cover the cost of treatment themselves."
