Researchers find way to get beneficial effects of estrogen without increasing woman's risk of cancer

Researchers at UT Southwestern Medical Center have pinpointed a set of biological mechanisms through which estrogen confers its beneficial effects on the cardiovascular system, independent of the hormone's actions on cancer. Their investigation suggests that drugs targeting a specific subpopulation of estrogen receptors found outside the cell nucleus might activate the cardiovascular benefits of estrogen without increasing cancer risk.

Excessive, uncontrolled vascular growth leads to development of cavernomas: Researchers

Benign vascular malformations known as cavernomas can occur in many tissues of the body. These abnormalities are characterized by enlarged, instable and unstructured blood vessels. Cavernomas of medical relevance are primarily those of the brain, which develop approximately in one out of two hundred people. In the brain, such growths often remain unnoticed and are typically found by chance in MRI scans. If they grow larger, they often cause unspecific symptoms such as headaches or dizziness.

Imaging algorithm helps reduce cumulative radiation exposure and number of CT, CTA, perfusion studies

A large, academic medical center implemented an imaging algorithm that allowed radiologists to successfully reduce the cumulative radiation exposure and number of computed tomography (CT) angiography (CTA) and CT perfusion studies performed on patients with aneurysmal subarachnoid hemorrhages (a form of stroke), according to a study published in the July issue of the American Journal of Roentgenology (www.ajronline.org).

Ultrasound-guided diffuse optical tomography holds promise for ascertaining early-stage invasive breast cancer

By combining two relatively inexpensive technologies based on sound and light waves, researchers hope to lower the rate at which women undergo breast biopsies for suspicious lesions. Results of the study on ultrasound-guided optical tomography are published in the online edition and the August print issue of Radiology.

Cytochrome P450 plays important role in management of high blood pressure: Researchers

Researchers have found that increasing certain proteins in the blood vessels of mice, relaxed the vessels, lowering the animal's blood pressure. The study provides new avenues for research that may lead to new treatments for hypertension.

NHLBI funds nine research grants to determine safety and efficacy of red blood cell transfusions

The National Heart, Lung, and Blood Institute, part of the National Institutes of Health, is funding nine research grants to determine if the safety and efficacy of red blood cell transfusions vary depending on how long the cells have been stored. One of the grants supports the first large, multi-center, randomized clinical trial to compare outcomes in heart surgery patients who receive transfusions of red blood cells that have been stored for shorter or longer amounts of time.

Investigators discover new way to harness thrombin's anti-blood clotting properties

In research led by a Saint Louis University investigator, molecular biologists have discovered a way to harness the enzyme thrombin's anti-blood clotting properties. The finding opens the door to new medications that will treat diseases related to thrombosis, the presence of blood clots in blood vessels, which is responsible for nearly a third of all deaths in the U.S.

Stem cell therapy leads to development of blood vessel, bone marrow masses

Following stem cell therapy, an adult patient experienced a new and previously unrecognized complication, which required removal of one of the kidneys, according to a case report appearing in an upcoming issue of the Journal of the American Society Nephrology (JASN). The report suggests that stem cell therapy may cause patients to develop blood vessel and bone marrow masses, the long term effects of which are unknown.

Constipation prophylaxis in sickle cell patients needs increased attention

Not all patients with sickle cell disease receive laxatives after being treated with narcotics, despite recommendations from a collaborative panel of pediatric experts. These are the findings from a Nationwide Children's Hospital study examining patients from 29 pediatric hospitals, and appearing in Pediatric Blood & Cancer.

Chelsea presents Northera study data at International Congress on Parkinson's Disease and Movement Disorders

Chelsea Therapeutics International, Ltd. announced that data from its pivotal studies of Northera™ (droxidopa) in symptomatic neurogenic orthostatic hypotension was presented during a poster session and featured in a symposium highlighting the role of norepinephrine (NE) deficiency in Parkinson's disease at the 14th International Congress on Parkinson's Disease and Movement Disorders in Buenos Aires, Argentina.

Alzheimer's disease may damage brain

Alzheimer's disease has long been studied primarily as a disease of neurons. But researchers have now shown how the disease may be damaging the brain by choking off blood flow. In experiments published June 10 in Neuron, scientists at Rockefeller University reveal that amyloid-β, which builds up around brain cells in Alzheimer's patients, interacts with a common blood clotting agent to increase clotting in the arteries that feed the brain.

Nurse with enhanced clinical skills detects same breast abnormalities as surgeon

UK researchers have developed an Initiative that could help hospitals prevent delays to the two-week cancer target, following the reduction in junior doctors' working hours due to the European Working Time Directive. A specially trained nurse practitioner and consultant breast surgeon who examined 126 women referred to a symptomatic breast disease clinic picked up the same breast abnormalities in 92% of cases.

Children born after ART at increased risk of congenital malformation

Couples considering undergoing assisted reproductive technology (ART) treatment should be informed about the increased risk of congenital malformation posed by the use of ART, the annual conference of the European Society of Human Genetics will hear today (Monday). Dr. G-raldine Viot, a clinical geneticist at the Maternit- Port Royal hospital, Paris, France, will say that she believed that most doctors working in ART clinics in France only told couples about such risks if they were asked specific questions.

Discarded livers have potential to be reengineered into usable replacement organs: Researchers

A team led by researchers from the Center for Engineering in Medicine at Massachusetts General Hospital has developed a technique that someday may allow growth of transplantable replacement livers. In their report that will be published in Nature Medicine and is receiving early online release, the investigators describe using the structural tissue of rat livers as scaffolding for the growth of tissue regenerated from liver cells introduced through a novel reseeding process.

In vitro fertilization ups the risk of birth defects: study

Researchers have found from a large scale study that in vitro fertilization of IVF is associated with an increased risk of birth defects in the baby. They urge doctors treating patients with infertility to routinely warn them about these risks. The study involved 33 centers for IVF in France and covered over 15,000 births from 2003 to 2007. This study is the largest till date.
