Scientists identify gene responsible for abdominal aortic aneurysms

Medical scientists have for the first time identified a gene responsible for a fatal abdominal condition that afflicts tens of thousands of people across the world.

Evolutionary 'breakpoints' on chromosomes may lead to canine cancer

North Carolina State University researchers have uncovered evidence that evolutionary "breakpoints" on canine chromosomes are also associated with canine cancer. Mapping these "fragile" regions in dogs may also have implications for the discovery and treatment of human cancers.

Using sub-nanometre cages to identify molecules

Reliable and accurate single-molecule medical diagnosis is a step closer to reality with the development a new technique by Cambridge University researchers which uses sub-nanometre “cages” to capture and identify molecules.

Cancer cells maintain rapid proliferation due to PK-M2 enzyme

Cancer cells maintain their life-style of extremely rapid growth and proliferation thanks to an enzyme called PK-M2 (pyruvate kinase M2) that alters the cells' ability to metabolize glucose - a phenomenon known as the Warburg effect.

The brain and the heart may not be so different after all

What do heart disease and dementia have in common? Perhaps more than meets the eye, according to researchers at the University of Rochester Medical Center.

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.

Reduced diversity of intestinal microbiota associated with increased risk of allergic disease

Oversensitivity diseases, or allergies, now affect 25 per cent of the population of Denmark. The figure has been on the increase in recent decades and now researchers at the Copenhagen Prospective Studies on Asthma in Childhood (COPSAC), University of Copenhagen, are at last able to partly explain the reasons.

Measles virus develops a strategy of diabolic elegance

Mayo Clinic researchers have discovered why measles, perhaps the most contagious viral disease in the world, spreads so quickly. The virus emerges in the trachea of its host, provoking a cough that fills the air with particles ready to infect the next host. The findings may also help in the fight against ovarian, breast and lung cancers.

Breakdown of unsaturated fats can induce complications in obese patients with acute pancreatitis

The toxic byproducts produced by the breakdown of unsaturated fats lead to a higher likelihood of severe inflammation, cell death and multi-system organ failure among acute pancreatitis patients who are obese, say researchers at the University of Pittsburgh School of Medicine.

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.

Study reveals what causes lysosome to overflow in Batten disease

Waste management is a big issue anywhere, but at the cellular level it can be a matter of life and death. A Weizmann Institute study, published in the Journal of Cell Biology, has revealed what causes a molecular waste container in the cell to overflow in Batten disease, a rare but fatal neurodegenerative disorder that begins in childhood.

Study outlines evolution of malaria, leishmaniasis and trypanosomiasis

One of the most comprehensive analyses yet done of the ancient history of insect-borne disease concludes for the first time that malaria is not only native to the New World, but it has been present long before humans existed and has evolved through birds and monkeys.

Increasing TR2/TR4 expression can lead to higher fetal hemoglobin levels in sickle cell patients

A University of Michigan Health System laboratory study reveals a key trigger for producing normal red blood cells that could lead to a new treatment for those with sickle cell disease.

Exendin-4 drug could prevent later development of diabetes in children

Pediatric researchers who tested newborn animals with an existing human drug used in adults with diabetes report that this drug, when given very early in life, prevents diabetes from developing in adult animals. If this finding can be repeated in humans, it may become a way to prevent at-risk infants from developing type 2 diabetes.

BUSM researcher receives two NIH grants to study scleroderma

Boston University School of Medicine (BUSM) researcher Robert Lafyatis, MD, recently was awarded two grants from the National Institutes of Health's (NIH) National Institute of Arthritis and Musculoskeletal and Skin Diseases.

Scientists discover how to starve prostate cancer cells

Each year about 3300 Australian men die of prostate cancer. It's Australia's second worst cancer killer for men, matching the impact of breast cancer on women. Current therapies for prostate cancer include surgical removal of the prostate, radiation, freezing the tumour or cutting off the supply of the hormone testosterone-but there are often side-effects including incontinence and impotence.

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.

Clinical-grade viral vector can cure choroideremia

Researchers at Ohio State University Medical Center and Nationwide Children's Hospital have developed a viral vector designed to deliver a gene into the eyes of people born with an inherited, progressive form of blindness that affects mainly males.
