Discovery of type of retinal cell that sees motion

A research team combining high-energy physicists from the University of California, Santa Cruz, and neuroscientists from the Salk Institute in La Jolla, Calif., has discovered a type of retinal cell that may help monkeys, apes, and humans see motion.

Heart disease of the left main coronary artery is often an inherited condition that clusters in families

Moreover, they discovered that initially healthy siblings of a person with the condition were 2.5 times more likely to go on to develop some form of heart disease than were siblings of a patient with heart disease that did not relate to the left main coronary artery.

Algorithms for defibrillators

When an adult suffers a cardiorespiratory arrest the rapid application of an electrical discharge with a defibrillator can avoid sudden death in many cases. Nevertheless, defibrillation also has its impediment or enemy: time.

Botched production of insulin molecule may lead to diabetes

Picture a pretzel factory production line, with conveyer belts carrying the dough, formed into unbaked pretzels, down to the oven to be cooked.

Space flight makes bacteria more infectious

Space flight has been shown to have a profound impact on human physiology as the body adapts to zero gravity environments.

Biodiversity of protozoa may be much higher than previously realised

In contrast to previous findings, it seems that the global distribution of macro- and microorganisms might be similar. A study in the online open access journal, BMC Evolutionary Biology, shows that some protozoa are globally dispersed, while others are geographically restricted - by looking at a new fast-evolving DNA marker.

Carvedilol used for treatment for heart failure in adults may not be beneficial for children and teens

Preliminary findings indicate a heart failure medication used by adults, carvedilol, may not significantly improve heart failure outcomes for children and adolescents, according to an article in the September 12 issue of JAMA.

DES: friend or foe?

The current FDA approved stents (CYPHER and TAXUS) have been associated with late stent thrombosis (LST) (>30days following implantation) however, the mechanisms predictive of LST are poorly understood. Pathologic studies are one of the best methods for detailed analysis of morphologic changes that occur after placement of Drug Eluting Stents to determine the causes of LST.

Air pollution linked to poor lung function growth in children

Children who are chronically exposed to higher levels of air pollution show marked deficiencies in lung growth and function, and not just short-term breathing problems, according to researchers in Mexico.

Bak protein's deadly double whammy

When a cell is seriously stressed, say by a heart attack, stroke or cancer, a protein called Bak just may set it up for suicide, researchers have found.

Engineered blood vessels work like native tissue

Blood vessels that have been tissue-engineered from bone marrow adult stem cells may in the future serve as a patient's own source of new blood vessels following a coronary bypass or other procedures that require vessel replacement, according to new research from the University at Buffalo Department of Chemical and Biological Engineering.

High frequency of sperm abnormalities associated with reduced testicular volume in male lupus patients

The prognosis for systemic lupus erythematosus (SLE), an autoimmune disease that mainly affects women in their reproductive years, has improved recently, prompting a shift toward improving quality of life.

Software enhances breast MRI scans - helps radiologists reduce false positives

Using commercially available software to enhance breast scans done by magnetic resonance imaging (MRI) reduces the number of false positive identifications of malignant tumors and the subsequent need for biopsies, according to a new study.

Genetic data overturns long-held theory of limb development

Long before animals with limbs (tetrapods) came onto the scene about 365 million years ago, fish already possessed the genes associated with helping to grow hands and feet (autopods) report University of Chicago researchers in Nature.

Diets high in salt may increase stomach ulcers

Scientists from the Uniformed Services University of the Health Sciences (USU) have discovered that diets high in salt may increase the virulence of the pathogen Helicobacter pylori (H. pylori), which is the most common cause of ulcers in the stomach and duodenum.

High salt intake increases gene activity in the ulcer-causing bacterium Helicobacter pylori

Scientists have identified yet another risk from a high-salt diet. High concentrations of salt in the stomach appear to induce gene activity in the ulcer-causing bacterium Helicobacter pylori, making it more virulent and increasing the likelihood of an infected person developing a severe gastric disease.

CT colonoscopy has 90 percent agreement rate with optical colonoscopy

Nearly 90% of colon polyps greater than or equal to 6 mm in size detected at CT colonoscopy were demonstrated to represent true polyps at subsequent optical colonoscopy (the traditional method of viewing the colon and removing precancerous growths), according to a new study by researchers from the University of Wisconsin Hospital and Clinics in Madison, WI.

New system for restoring damaged or lost knee cartilage tissue

Knee osteoarthritis affects 30 million people worldwide, causing pain and joint stiffness and in severe cases restricted mobility.

Micell Technologies presents data on novel drug-eluting stents

Micell Technologies has announced that the Company will be presenting data on use of its supercritical fluid (SCF) surface modification technology for drug-eluting stents at the upcoming Society for Biomaterials 2007 Annual Meeting, April 19-21 2007 in Chicago, Illinois.

Study improves understanding of early ovarian cancer

A new University of Michigan Medical School study sheds light on cell defects that lead to one common type of ovarian cancer and puts forth a promising new mouse model that already is being used for preclinical drug testing.
