Mutation on surface of human red blood cells provides protection against vivax malaria

A mutation on the surface of human red blood cells provides protection against malaria caused by the parasite Plasmodium vivax, research led by Case Western Reserve University School of Medicine shows.

FDA issues draft guidance on artificial pancreas system

The U.S. Food and Drug Administration today issued draft guidance designed to help investigators and manufacturers as they develop and seek approval for artificial pancreas device systems to treat type 1 diabetes.

The Lipitor story: Drug companies brace for losses as patents expire on this and other popular medications

News outlets analyze the impact that generic Lipitor could have on costs and the "era of 'blockbuster drugs'" as well as the strategies from Lipitor's maker to block its generic competitors. Meanwhile, some of these generics are already reaching the marketplace.

Low-carbohydrate diet may help prepubescent girls avoid obesity associated risks

A low-carbohydrate diet may help prepubescent girls avoid some risks associated with obesity, such as diabetes and heart disease, according to research from the University of Alabama at Birmingham.

Cheaper test as effective as a more sophisticated test in guiding anti-retroviral drug treatment

A cheaper laboratory test that helps guide anti-retroviral drug treatment for people with HIV/AIDS may be just as effective as a more sophisticated test, a group of international researchers has found - a discovery that could be particularly important in rural Africa.

Insights into causes of Idiopathic Pulmonary Fibrosis

Tracking individual cells within the lung as they move around and multiply has given Duke University researchers new insights into the causes of Idiopathic Pulmonary Fibrosis (IPF) a disease which can only be treated now by lung transplantation.

Yale researchers monitor growth of laboratory-engineered blood vessels after implantation

Using magnetic resonance imaging (MRI) and nanoparticle technology, researchers from Yale have devised a way to monitor the growth of laboratory-engineered blood vessels after they have been implanted in patients. This advance represents an important step toward ensuring that blood vessels, and possibly other tissues engineered from a patient's own biological material, are taking hold and working as expected.

Majority of Californians requiring mental health treatment receive inadequate services

Nearly 2 million adults in California, about 8 percent of the population, need mental health treatment, but the majority receive no services or inadequate services, despite a state law mandating that health insurance providers include mental health treatment in their coverage options, a new report by the UCLA Center for Health Policy Research shows.

Researchers reveal ambivalent role of CXCL12/CXCR4 molecule in myocardial infarction

The chemokine CXCL12 acts as a chemical signal which mobilizes hematopoietic and other types of stem cells to leave the bone marrow and enter the circulation. Secretion of CXCL12 also guides these cells to sites at which the perfusion of tissue is sub-optimal due to localized obstruction of blood flow. These capabilities have made CXCL12 and its cognate receptor CXCR4 interesting candidates for therapies aimed at mitigating the effects of damage to the heart caused by myocardial infarction.

Immune system stimulant used as suppressor to treat chronic graft-versus-host disease

In a study that seems to pivot on a paradox, scientists at Dana-Farber Cancer Institute have used an immune system stimulant as an immune system suppressor to treat a common, often debilitating side effect of donor stem cell transplantation in cancer patients. The effect, in some cases, was profound.

Synthetic human tissue aids in testing photoacoustic and ultrasonic imaging technologies

The precise blending of tiny particles and multicolor dyes transforms gelatin into a realistic surrogate for human tissue. These tissue mimics, known as "phantoms," provide an accurate proving ground for new photoacoustic and ultrasonic imaging technologies.

First neurovascular unit opens at Krembil Neuroscience Centre

The first neurovascular unit (NVU) in Canada opened today at the Krembil Neuroscience Centre, Toronto Western Hospital, which is part of the University Health Network.

First study to investigate risk factors for CCSVI in patients without neurological disease

The first study to investigate risk factors for the vascular condition called CCSVI (chronic cerebrospinal venous insufficiency) in volunteers without neurological disease has identified what the researchers call a remarkable similarity between this condition and possible or confirmed risk factors for multiple sclerosis.

Study investigates why American Indians with African ancestry were more fertile

American Indians with African ancestry outdid 'full bloods' in reproductive terms in the early 1900s, despite the odds being against them, according to a new study by Michael Logan from the University of Tennessee in the US. Their increased fertility occurred at a time when things were not going particularly well for full bloods either - in social, economic and health terms.
