Introduced foxes transformed vegetation on Aleutian Islands from lush grasslands to tundra
Huge colonies of seabirds accustomed to nesting on islands free of predators began disappearing when fur traders started introducing foxes onto islands in the Aleutian archipelago in the 18th century. The ground-nesting birds made easy meals for the foxes. A study published this week in the journal Science now shows that the effects of the introduced foxes rippled through entire island ecosystems...Stem cells from brain transformed to produce insulin at Stanford
With careful coaxing, stem cells from the brain can form insulin-producing cells that mimic those missing in people with diabetes, according to a paper published in the April 26 issue of PLoS Medicine. Although the work is not yet ready for human patients, Seung Kim, MD, PhD, the lead author and assistant professor of developmental biology at the Stanford University School of Medicine, sai...Rare surgery performed to remove pancreas, prevent diabetes
In a 12-hour, dual-stage surgery known to be performed at only two other centers in the U.S., doctors at the University of Alabama at Birmingham on Tuesday returned a patient's own insulin-producing cells to him after surgically removing his pancreas to eliminate constant, severe pain from chronic pancreatitis. The patient, Leonard Stewart, 47, of Panama City, Fla., remained anesthetized i...Value of services performed by insects tops $57 billion in US
Think twice before you blithely swat, stomp, curse or ignore insects, says Cornell University entomologist John Losey, who co-authored a study that shows the dollar value of some of those insect services is more than $57 billion in the United States annually. The research appears in the journal BioScience today (April 1). "Most insects tirelessly perform functions that improve our environm...Researchers offer clues to how leaves patterns are formed
Pick up a leaf and it is hard not to notice the pattern made by the veins. For years, biologists, mathematicians and even poets and philosophers have tried to decipher the rules and regulations behind those varied designs and now new research published in part at the University of Alberta offers a big clue to how those patterns are formed. "For years people have been trying to understand...293 cell line slides ( human: kidney; transformed with adenovirus 5 DNA ) from GeneTex
Description:Human 293 cells were cultured in Minimum Essential Medium (Eagle) with 2 mM L-glutamine and harvested at the log phase of growth. In order to keep the antigens in their native forms, cells were fixed in acetone-methanol. The cells are arrayed on a 12-well (5 mm) adhesive coated slide, with each wells surface specifically treated to enhance cellular attachment and to minimize background staining...3T3 cells (RSV-transformed) from Exalpha Biologicals, Inc.

A minimally invasive direct coronary artery bypass (MIDCAB) procedure was performed at Pittsburgh while the patient was awake. The operation was done under thoracic epidural anesthesia. This approach may help in discharging the patient early from the hospital. Dr. Zenati from the team of doctors who performed the surgery said that patients who are operated in this way may not have to go t...Stroke risk factors:how informed are we?
The journal of the American Medical Association published a recent comparative study done by researchers from the University of Cincinnati who analyzed results from a telephone survey of people living in greater Cincinnati// region. The survey involved 2170 respondents who were asked to name up to three stroke warning signs and risk factors. This was compared with a similar survey cond...Epilepsy Drug Valproate and Lamotrigine Linked To Malformed Fetus
In a study in the March issue of Neurology, the epilepsy drug Valproate has been linked to malformation of fetus //when prescribed to pregnant ladies. For pregnant women with epileptic seizures, often the drug Valproate is prescribed. The new study shows that women who took the drug in their first trimester of pregnancy often gave birth to malformed babies. Data for the st...Poll Finds Many Americans Misinformed About Cancer
American Cancer Society researchers conducted in interesting national survey that was led by Ted Gansler, M.D., M.B.A to look at the prevailing myths about cancer //in the minds of the public. They did a phone survey of 957 adults with no history of cancer to assess their understanding of the disease and its management, and also identify any associated misconceptions.
