Estrogen therapy can reverse progression of pulmonary hypertension

UCLA researchers have found that the hormone estrogen may help reverse advanced pulmonary hypertension, a rare and serious condition that affects 2 to 3 million individuals in the U.S., mostly women, and can lead to heart failure.

Scientists uncover unknown fail-safe pathway for inherited disorders

Scientists at the University of California, San Diego School of Medicine have uncovered a previously unknown fail-safe (compensatory) pathway that potentially protects the brain and other organs from genetic and environmental threats.

Researchers identify promising new therapies for ependymoma

Researchers have identified promising new therapies for ependymoma, a rare tumor with few treatment options. St. Jude Children's Research Hospital investigators led the effort, which used a new, faster drug development system that combines the latest drug screening technology with the first accurate animal model of the tumor.

Experts urge women to recognize warning signs of ovarian cancer, receive appropriate screenings

Ovarian cancer is a rare but often deadly disease that can strike at any time in a woman's life. It affects one in 70 women and in the past was referred to as a silent killer, but researchers have found there are symptoms associated with ovarian cancer that can assist in early detection. Experts at Northwestern Memorial say the best defense is to make use of preventive methods, understand the risks and recognize potential warning signs of ovarian cancer.

Something like 'Contagion' could happen for influenza

In the new movie "Contagion," fictional health experts scramble to get ahead of a flu-like pandemic as a drug-resistant virus quickly spreads, killing millions of people within days after they contract the illness.

ITA president hosts International Small Bowel Transplant Symposium

Fifty-two year-old Paul McNeel, a fire chief from Leonardtown, Maryland was 37 in 1996 when a sudden health problem caused the loss of his small intestine. Almost all of it had to be surgically removed to save his life. For 13 years after that, McNeel continued to fight fires and stayed alive only because he fed himself a special liquid formula through a tube that went from a port in his chest directly to his heart and into his bloodstream.

Fast-track genetic diagnosis for hearing loss

Over 28 million Americans are hearing impaired, and 50 percent of these cases can be traced to genetic causes. The condition can be especially challenging for children born hearing impaired because spoken language, reading, and cognitive development are tied to hearing. That makes early diagnosis essential for identifying appropriate therapy and treatment.

DiscoveryBioMed receives NIDDK grant for Cystic Fibrosis Corrector Ligand Drug Discovery program

DiscoveryBioMed, Inc. (DBM), a human cell-based drug discovery company, learned recently that its Cystic Fibrosis Corrector Ligand (CFCL) Drug Discovery program will be funded by the NIH. The two-year award will focus on validation and prioritization of several lead CFCL chemical classes, drugs that correct the most common cystic fibrosis (CF) disease-causing mutation.

Scientists decode new mechanism that regulates cell polarity in epithelial tissues, neurons

In the course of examining the Drosophila tumor suppressor gene (Dlg), scientists at the Helmholtz Zentrum München have succeeded in decoding a new mechanism that regulates cell polarity in epithelial tissues or in neurons in the brain.

Research identifies 6 critical deafness-related mutations in Israeli Jewish, Palestinian Arab families

Precise diagnosis of disease and developmental syndromes often depends on understanding the genetics underlying them. Most cases of early onset hearing loss are genetic in origin but there are many different forms. Heretofore, it has been difficult to identify the gene responsible for the hearing loss of each affected child, because the critical mutations differ among countries and populations.

New imaging method could better assess extent of nerve damage

A new imaging technique could help doctors and researchers more accurately assess the extent of nerve damage and healing in a live patient. Researchers at Laval University in Qu-bec and Harvard Medical School in Boston aimed lasers at rats' damaged sciatic nerves to create images of the individual neurons' insulating sheath called myelin.

Computer models that predict response to treatment

Details of computer models that can predict the chances of a patient responding to their HIV drugs with 80% accuracy are published today in the journal AIDS. The models were developed by the HIV Resistance Response Database Initiative (RDI) using almost half a million pieces of data from approximately 6,000 clinical cases from hundreds of clinics around the world. The models are now available online as part of an experimental treatment support tool, HIV-TRePS.

UB transgenic mouse model of Timothy Syndrome improves understanding of autism

The first transgenic mouse model of a rare and severe type of autism called Timothy Syndrome is improving the scientific understanding of autism spectrum disorder in general and may help researchers design more targeted interventions and treatments.

Women with BRCA gene mutations at risk of developing cancers at earlier ages

A new analysis has found that women who develop certain hereditary cancers develop them at earlier ages than women in the previous generation. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the results point to the importance of tracking younger ages of cancer diagnosis to determine when to provide counseling, screening, and treatment services.

Women with BRCA gene mutation develop breast cancer earlier than their ancestors

Women with a deleterious gene mutation are diagnosed with breast cancer almost eight years earlier than relatives of the previous generation who also had the disease and/or ovarian cancer, according to new research from The University of Texas MD Anderson Cancer Center.

New treatment strategy for dominant forms of muscular dystrophy

Investigators at The Research Institute at Nationwide Children's Hospital are studying a potential new treatment strategy for dominant forms of muscular dystrophy, thanks to preliminary funding from The Ohio State University Center for Clinical and Translational Science.

Common genetic variant may predispose people to acute dissections

Richard Holbrooke, John Ritter, Lucille Ball, Jonathan Larson and Great Britain's King George II were all taken by the same silent killer: an acute aortic dissection. Now, scientists led by researchers at The University of Texas Health Science Center at Houston and Baylor College of Medicine have found an association with a common genetic variant in the population that predisposes people to acute dissections and can approximately double a person's chances of having the disease.

WSU researcher receives $418,000 NINDS grant to study spinal muscular atrophy

Graham Parker, Ph.D., assistant professor of research in the Department of Pediatrics at Wayne State University's School of Medicine, was awarded $418,000 from the National Institute of Neurological Disorders and Stroke of the National Institutes of Health to study how a particular gene might be involved in the progression of spinal muscular atrophy (SMA) - the number one genetic killer of children younger than 2 years old.

Novel solution for purifying stem cell mixtures

Stem cells show great potential to enable treatments for conditions such as spinal injuries or Lou Gehrig's disease, and also as research tools. One of the greatest problems slowing such work is that researchers have found major complications in purifying cell mixtures, for instance to remove stem cells that can cause tumors from cells developed for use in medical treatments.

Study identifies genes never before linked to antibiotic resistance in enterococci

An analysis of the genome of a superbug has yielded crucial, novel information that could aid efforts to counteract the bacterium's resistance to an antibiotic of last resort.
