Scarring prevents precipitous decline in heart function after cardiac injury

After a heart attack, the portions of the heart damaged by a lack of oxygen become scar tissue. Researchers have long sought ways to avoid this scarring, which can harden the walls of the heart, lessen its ability to pump blood throughout the body and eventually lead to heart failure. But new research from the University of North Carolina at Chapel Hill School of Medicine shows that interrupting this process can weaken heart function even further.

EPO-secreting engineered vessels could reverse anemia

Patients who rely on recombinant, protein-based drugs must often endure frequent injections, often several times a week, or intravenous therapy. Researchers at Children's Hospital Boston demonstrate the possibility that blood vessels, made from genetically engineered cells, could secrete the drug on demand directly into the bloodstream.

CCCBD scientist to receive 2011 V Foundation Translational Research Grant

Scientists at the Children's Center for Cancer and Blood Diseases (CCCBD) and the Keck School of Medicine of the University of Southern California, have been awarded a highly competitive translational research grant of $600,000 from The V Foundation for Cancer Research.

Johns Hopkins researchers unravel how breast cancer metastasizes

The spread of breast cancer is responsible for more than 90 percent of breast cancer deaths. Now, the process by which it spreads—or metastasizes—has been unraveled by researchers at Johns Hopkins. Reporting in two papers, the researchers have discovered the switch that enables breast cancer cells to travel to and be received in the lungs.

Viagra may improve antitumor immunity in people with melanoma

At first it sounds like good news: The body's own immune system gets active in almost every cancer - however, not necessarily for the benefit of the patient. "We distinguish between two different types of immune response," says Professor Dr. Viktor Umansky, immunologist at DKFZ and University Medical Center Mannheim. "On the one hand, cells of the immune system specifically attack tumor cells.

Electronic Nose can diagnose TB in symptomatic patients

A new hand-held device called the Electronic Nose, which has the potential to diagnose tuberculosis (TB) in symptomatic patients, was awarded a $950,000 grant from Grand Challenges Canada and the Bill & Melinda Gates Foundation today to support further development and testing of this ground-breaking technology.

Mouse anti-aging study generates expert commentary

Age related changes like wrinkles, muscle wasting and cataracts could be delayed in mice, say researchers in the US. They achieved the feat by removing old cells that had stopped dividing. These accumulate naturally with age. The scientists believe their findings could eventually “really have an impact” in the care of the elderly. Experts said the results were “fascinating”, but should be taken with a bit of caution.

Slowing aging by cleaning away old cells: Study

Researchers have found a novel way of reversing the aging process. They found that a special category of cells, known as senescent cells, are bad actors that promote the aging of the tissues. Cleansing the body of the cells, they hope, could postpone many of the diseases of aging. This could pave the way for drugs that would keep human tissues healthier longer, but it is unclear until further testing is done whether such drugs could eventually help people live longer.

Gene therapy and stem cell transplantation successfully reverse hemophilia A

For the first time, researchers have combined gene therapy and stem cell transplantation to successfully reverse the severe, crippling bleeding disorder hemophilia A in large animals, opening the door to the development of new therapies for human patients.

New study in fruit flies offers clues to delay human aging

One of the few reliable ways to extend an organism's lifespan, be it a fruit fly or a mouse, is to restrict calorie intake. Now, a new study in fruit flies is helping to explain why such minimal diets are linked to longevity and offering clues to the effects of aging on stem cell behavior.

Eliminating senescent cells could prevent or delay onset of age-related disorders

Researchers at Mayo Clinic have shown that eliminating cells that accumulate with age could prevent or delay the onset of age-related disorders and disabilities. The study, performed in mouse models, provides the first evidence that these "deadbeat" cells could contribute to aging and suggests a way to help people stay healthier as they age.

Pupil can constrict without any input from brain

You've seen it on television: A doctor shines a bright light into an unconscious patient's eye to check for brain death. If the pupil constricts, the brain is OK, because in mammals, the brain controls the pupil. Or does it? Now, researchers at Johns Hopkins have discovered that in most mammals, in fact in most vertebrates, the pupil can constrict without any input from the brain.

Nmnat1 protein may help prevent brain damage in babies with cerebral palsy

Scientists at Washington University School of Medicine in St. Louis have shown that a protein may help prevent the kind of brain damage that occurs in babies with cerebral palsy.

Articles explore clinical dilemma about children's behavioral problems

Clinicians often face the challenge of trying to make sense of conflicting reports from parents, teachers, and children about a child's behavioral problems. However, a better understanding of the source and nature of these disagreements may provide important information that could improve treatment and outcomes. A group of articles in the current issue of Journal of Child and Adolescent Psychopharmacology, a peer-reviewed journal published by Mary Ann Liebert, Inc., explores this challenging clinical dilemma.

Glyphosine can prevent development of type 1 diabetes

Researchers at the University of Colorado School of Medicine have found a specific molecule that can prevent the development of type 1 diabetes in mice and has a similar effect on human cells from diabetic patients.
