UCSD molecular biologist to receive Breakthrough Prize in Life Sciences

Napoleone Ferrara, MD, PhD, the molecular biologist credited with helping decipher how tumors grow and now senior deputy director for basic sciences at the University of California, San Diego Moores Cancer Center, was today named one of 11 recipients of the inaugural Breakthrough Prize in Life Sciences, which comes with a $3 million cash award.

New bio-mimicking therapeutics could help treat skin wounds

In "before" and "after" photos from advertisements for wound-healing ointments, bandages and antibiotic creams, we see an injury transformed from an inflamed red gash to smooth and flawless skin. What we don't appreciate is the vital role that our own natural biomolecules play in the healing process, including their contribution to the growth of new cells and the development of new blood vessels that provide nutrients to those cells.

Plasma plays a crucial part in determining how blood flows

Blood flows differently than water. Anyone who has ever cut themselves knows that blood flows viscously and rather erratically. The similarity between blood and ketchup is something not only filmmakers are aware of. Experts refer to these materials as "non-Newtonian fluids," of which ketchup and blood are prime examples.

Tranylcypromine may also hold promise in treating sickle cell disease

An antidepressant drug used since the 1960s may also hold promise for treating sickle cell disease, according to a surprising new finding made in mice and human red blood cells by a team from the University of Michigan Medical School.

Study identifies regions of genes linked to Beh-et's disease

Researchers don't know the exact cause of Beh-et's disease, a chronic condition that leads to oral and genital sores and serious complications such as blindness, but new research brings better understanding to what makes some people more susceptible to being affected.

Researchers identify new molecular pathway involved in alveoli growth

In a study of mice, researchers at Johns Hopkins have identified a new molecular pathway involved in the growth of tiny air sacs called alveoli that are crucial for breathing. The scientists say their experiments may lead to the first successful treatments to regrow the air sacs in people who suffer from diseases such as emphysema in which the air sacs have been destroyed by years of smoking.

Pairing Avastin with dasatinib can stop lethal spread of glioblastoma multiforme

The drug bevacizumab, also known by the trade name Avastin, shrinks tumors briefly in patients with an aggressive brain cancer known as glioblastoma multiforme, but then they often grow again and spread throughout the brain for reasons no one previously has understood. Now, Mayo Clinic researchers have found out why this happens.

Blocking C5a protein prevents low birth weight in babies born to pregnant women with malaria

An international team of tropical medicine researchers have discovered a potential method for preventing low birth weight in babies born to pregnant women who are exposed to malaria. Low birth weight is the leading cause of infant death globally.

Novel approach uses adult stem cells to save sight of diabetes sufferers

Scientists at Queen's University Belfast are hoping to develop a novel approach that could save the sight of millions of diabetes sufferers using adult stem cells.

CATT study clarifies value of genetic testing for age-related macular degeneration

New findings from a landmark clinical trial show that although certain gene variants may predict whether a person is likely to develop age-related macular degeneration (AMD), a potentially blinding eye disease that afflicts more than nine million Americans, these genes do not predict how patients will respond to Lucentis- and Avastin-, the two medications most widely used to treat the "wet" form of AMD.

University of Utah geneticists engineer mice that develop clear cell sarcoma

Geneticists led by University of Utah Nobel Prize Laureate Mario R. Capecchi, Ph.D., have engineered mice that develop clear cell sarcoma (CCS), a significant step in better understanding how this rare and deadly soft tissue cancer arises. The mouse model also can potentially speed the development of drugs to target genes that must be activated for the cancer to form.

Blood vessels play an important role in preventing spread of tumour cells

A lack of the protein endoglin in the blood vessels of tumour-bearing mice enables the spread of daughter tumours, according to researchers at Karolinska Institutet and Lund University in Sweden in a study published in the scientific periodical The Journal of Experimental Medicine. Given that the tumour vasculature constitutes an important barrier to the spread of cancer cells, the team suggests that drugs should be developed to strengthen the blood vessels' protective function.

Study questions high rate of cesarean deliveries in women with aneurysms

For women with aneurysms involving the brain blood vessels, pregnancy and delivery don't appear to increase the risk of aneurysm rupture, reports a paper in the February issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Sunitinib does not cause lingering risks for cancer patients after their treatment ends

Studies in animals have raised concerns that tumors may grow faster after the anticancer drug sunitinib is discontinued. But oncologists and physicists who collaborated to analyze data from the largest study of patients with kidney cancer convincingly demonstrate that such tumor acceleration does not occur in humans.

LPA genetic variant increases risk of heart valve calcification

Researchers have found a genetic variant that doubles the likelihood that people will have calcium deposits on their aortic valve. Such calcification, if it becomes severe, can cause narrowing or a blockage of the aortic valve, a condition called aortic stenosis.

Drug-carrying nanoparticles have another hurdle to overcome - escaping the bloodstream

Many medically minded researchers are in hot pursuit of designs that will allow drug-carrying nanoparticles to navigate tissues and the interiors of cells, but University of Michigan engineers have discovered that these particles have another hurdle to overcome: escaping the bloodstream.

Patients undergoing major vascular surgery procedures are at increased risk of stroke

Patients undergoing major vascular surgery procedures are at increased risk of stroke, leading to a high mortality rate and prolonged hospitalization, according to a study in the February issue of Anesthesia & Analgesia, official journal of the International Anesthesia Research Society (IARS).

New method for detecting cancer by measuring elasticity of tumours

As the first countries in the world, Norway and France will be testing a completely new method for detecting cancer. This is done by measuring the elasticity of tumours. The method is called elastography. You may as well learn this new word right away; in a few years, elastography may be as common as X-rays.

Cloaked nanoparticles escape immune system surveillance to reach desired target

By cloaking nanoparticles in the membranes of white blood cells, scientists at The Methodist Hospital Research Institute may have found a way to prevent the body from recognizing and destroying them before they deliver their drug payloads. The group describes its "LeukoLike Vectors", or LLVs, in the January issue of Nature Nanotechnology.
