New compounds promising candidates for neurodegenerative disease drug development

Scientists have developed a novel strategy for tackling neurodegenerative diseases such as Huntington's disease: encouraging an individual's own cells to "eat" the malformed proteins that lead to the disease.

Surfactant replacement therapies improve neonatal survival in premature infants with neonatal respiratory distress syndrome

Data presented at the Pediatric Academic Societies, Annual Meeting demonstrate that premature infants with neonatal Respiratory Distress Syndrome (RDS) have a nearly 20% better chance of survival if they are treated with Curosurf, (poractant alfa) Intratracheal Suspension rather than either of two competing surfactant therapies.

Sperm from diabetic men have greater levels of DNA damage which may affect their fertility

In the first study to compare the quality of DNA in sperm from diabetic and non-diabetic men, researchers at Queen’s University Belfast showed that the DNA in the nuclei of the sperm cells had greater levels of fragmentation in diabetic men, and that there were more deletions of DNA in the tiny, energy-generating structures in the cells called mitochondria.

Premature birth rate in U.S. linked to increased use of pesticides and nitrates

The growing premature birth rate in the United States appears to be strongly associated with increased use of pesticides and nitrates, according to work conducted by Paul Winchester, M.D., professor of clinical pediatrics at the Indiana University School of Medicine.

Discovery may lead to new treatments for lung cancer and blood cancer

The research team uses a genetically modified mouse that produces a muted and constantly active CAAX protein. This is a new model for an extremely aggressive lung cancer and a mild form of blood cancer. In these mice, the production of an enzyme called GGTas1 can also be stopped.

PET-CT is better for early detection of muscular lymphoma than CT alone

For the study, PET-CT was used to image 305 patients with lymphoma. Twelve of these patients had muscular involvement in which 10 were biopsy proven and two were proven by imaging follow-up.

Percutaneous radiofrequency ablation of liver tumors safe and effective

Percutaneous imaging guided radiofrequency ablation (RFA) of hepatocellular carcinoma is a safe and effective technique, with benefits such as reduced post-procedural pain and length of hospital stay, according to a study conducted by researchers from Changi General Hospital in Singapore.

Heart-assist devices may help some end-stage heart failure patients avoid transplant

Implanted pumps improved heart function enough in a small percentage of patients awaiting a heart transplant that they were able to leave the hospital without a pump and without a new heart, according to a study in Circulation: Journal of the American Heart Association.

Functional anesthetic discography allows diagnosis of lower back pain cause

Functional anesthetic discography (FAD), a new diagnostic procedure involving injecting anesthetic directly into a spinal disc, can be used to confirm the presence of injured discs as the source of a patient's lower back pain symptoms, according to a new study by researchers from Winthrop-University Hospital in Mineola, NY.

New option for soft-tissue imaging in interventional radiology procedures

Soft-tissue cross-sectional imaging acquired on a flat panel C-arm fluoroscopic unit located in the interventional radiology area is feasible and useful for interventional radiology procedures, avoiding the necessity of sending patients out to a CT scanner, according to a new study by researchers from the Baptist Cardiac & Vascular Institute in Miami, FL.

MR spectroscopy of choline levels shows promise as a marker of fetal lung maturity

The researchers performed high resolution MRS on 15 amniotic fluid samples for evaluation of fetal lung maturity between 34 and 40 weeks gestation and were analyzed using trimethysilylpropionic acid (TSP) as a reference standard.

10.3 percent of U.S. adults appear to have problems with drug use or abuse

Approximately 10.3 percent of U.S. adults appear to have problems with drug use or abuse during their lives, including 2.6 percent who become drug dependent at some point, according to a report in the May issue of Archives of General Psychiatry.

MR imaging helps predict recurrence in prostate cancer patients

MR images taken of prostate cancer patients prior to treatment that show that the cancer has spread outside the prostate gland capsule help predict whether the cancer will return, according to a recent study conducted by radiologists at the University of California-San Francisco.

Multitasking mental cells

In the mid-1990s, scientists at the University of Parma, in Italy, made a discovery so novel that it shifted the way psychologists discuss the brain. After researchers implanted electrodes into the heads of monkeys, they noticed a burst of activity in the premotor cortex when the animals clutched a piece of food.

MDCT eliminates need for catheter angiography for aortic injury diagnosis

Contrast-enhanced 64-MDCT that definitively reveals acute trauma to the aorta does not need confirmation from invasive catheter angiography, which saves valuable time in treating patients in trauma centers, according to a new study by researchers from the Medical University of South Carolina in Charleston.
