Heart intervention doesn't outweigh medicine in study
... Co-authored by UK HealthCare's Linda and Jack Gill Heart Institute cardiologist Dr. David Booth, results of a five-year study released today showed that stable heart patients received no significant benefit in undergoing angioplasty when compared to patients treated with medication alone. The study, Clinical Outcomes Utilizing...This party doesn't start until the hosts arrive
... Their results, published in the Proceedings of the National Academy of Sciences, have broad implications for identifying and mitigating spreading disease in a global economy. Simultaneously understanding the invasion pathways of disease-causing organisms and their...'Failed' experiment yields a biocontrol agent that doesn't trigger antibiotic resistance
... ... The discovery also led to the startup of a promising new biotechnology firm that has already brought Wisconsin a dozen new, high-paying, highly skilled jobs. Filutowicz is a professor of bacteriology in the University of Wisconsin-...High BMI doesn't always spell obesity, Jackson Laboratory researchers show
... But the BMI has come under scrutiny lately, and other techniques that measure how the weight is distributed on the body are thought to provide a better way to assess risk. Now a study in mice by scientists at The Jackson Laboratory indicates that the usefulness o...Acetaminophen safe to use after heart attack but doesn't protect the heart
BETHESDA, MD. Acetaminophen is safe to use as a pain reliever and fever reducer after a heart attack, but it does not protect the heart muscle, a new study using sheep and rabbits concluded....... The study, using rabbits and sheep, could have implications for people who have suffered heart attacks, about a million people in the U.S. each year, said researcher Robert C. Gorman, a medical doctor a...In stretching, pain doesn't equal gain; but if NO isn't producing, stretching won't help
SAN FRANCISCO If you're a mouse, then stretching before you exercise is a good thing even as long as two weeks before your next cheese hunt or cat run. But if you're reading this for yourself, it's a bit more complicated. ...... When most of us think of stretching, we're imagining at a minimum jogging, and probably something more like downhill skiing or sprints. But when University of Michigan...Study finds evolution doesn't always favor bigger animals
Biologists have long believed that bigger is better when it comes to body size, since many lineages of animals, from horses to dinosaurs, have evolved into larger species over time. ...... But a study published this week by two biologists at the University of California, San Diego in an early online edition of the Proceedings of the National Academy of Sciences suggests that maxim, known as "Cope...If oxytocin eating role doesn't mature at birth, what other situations affect its impact?
STEAMBOAT SPRINGS, Colorado (July 19, 2005) More than 15 years ago Edward Stricker and Joseph Verbalis reported that oxytocin (OT) is involved in the neural control of food and salt intake in adult rats. Linda Rinaman at the University of Pittsburgh is investigating the anatomical organization of this system, and also is taking a developmental approach to determine how OT modulates eating and di...In a story reminiscent of David and Goliath, new research from Rockefeller University shows that sometimes the smallest molecules can be the most powerful. In the July 1 issue of Cell, Ulrike Gaul, Ph.D., and colleagues report that microRNAs serve very important, and very specific, functions during the early development of the fruit fly. ......First discovered a few years ago, microRNAs are short...To sea or not to sea: When it comes to salmon sex, size sometimes doesn't matter
The ones that stay and the ones that stray are biological puzzles among Pacific salmon, of whom the vast majority but not all travel thousands of miles to sea and back to the streams where they hatched. ... There are chinook salmon populations in Idaho in which an occasional male stays put and matures when only 6 inches long that is, he's able to fertilize eggs at even that diminutive size, sa...The first experimental evidence that birds can be deceived by camouflage in the same way that humans are deceived, is published today in Nature [3 March 2005]. ...... The idea that bold contrasting colours help to break-up the body's outline was rapidly adopted by many armies as long ago as the First World War. And in biology this idea of 'disruptive colouration' has long been used to explain ho...PUBLIC-health campaigns regularly plug exercise as a sure-fire way to avoid an early grave. But that message may be too simplistic. For an unhappy few, even quite strenuous exercise may have no effect on their fitness or their risk of developing diseases like diabetes. "There is astounding variation in the response to exercise. The vast majority will benefit in some way, but there will be a minor...A chemist at Washington University in St. Louis has found surprisingly tough enzymes in a bacterium that "just says no to acid."...Acid resistance is a valued trait for both pills and human pathogens. The bacterium Acetobacter aceti makes unusually acid-resistant enzymes in spades, which could make the organism a source for new enzyme products and new directions in protein chemistry. ...A. aceti...
