Scientists reveal potential new target for anti-malarial drugs

Scientists funded by the Wellcome Trust have identified a key mechanism that enables malaria-infected red blood cells to stick to the walls of blood vessels and avoid being destroyed by the body's immune system. The research, published today in the journal Cell, highlights an important potential new target for anti-malarial drugs.

Circulating tumor cells can reveal genetic signature of dangerous lung cancers

Using a miniature laboratory-on-a-chip device, a team of investigators at the Massachusetts General Hospital, led by Daniel Haber, M.D., Ph.D., and Mehmet Toner, Ph.D., both members of the MIT-Harvard Center for Cancer Nanotechnology Excellence (CCNE), has developed a method that detects and analyzes the genetic signature of rare tumor cells in the bloodstream.

Genetic change in dopamine transporter supports a role for dopamine signaling in ADHD

A genetic change in the dopamine transporter - one of the brain's dopamine-handling proteins - makes it behave as if amphetamine is present and "run backward," Vanderbilt University Medical Center investigators report this week in The Journal of Neuroscience.

Protein found in immune cells may be a reliable marker for schizophrenia risk

Schizophrenia is a severe and complex psychiatric illness that affects about 1% of the population. Diagnosis currently relies on subjective clinical interviews and the assessment of ambiguous symptoms, which frequently leads to delayed diagnosis and treatment. As such, biomarkers that would indicate schizophrenia risk or onset would be extremely useful.

Normal-looking sperm may have serious damage; scientists urge more care in selection

Intracytoplasmic sperm injection (ICSI), where a single sperm is injected into an egg to fertilise it, is increasingly used to help infertile men father children. Although the sperm chosen for the procedure may appear quite normal, researchers in the US have found that many of them in fact have DNA damage, which can decrease the chances of pregnancy.

Transgenic tomatoes as edible vaccine carriers for Alzheimer's disease

The humble tomato could be a suitable carrier for an oral vaccine against Alzheimer's disease, according to HyunSoon Kim from the Korea Research Institute of Bioscience and Biotechnology (KRIBB) in Korea and colleagues from Digital Biotech Inc. and the Department of Biological Science at Wonkwang University.

UAB joins elite brain cancer research group

Brain cancer experts at the University of Alabama at Birmingham (UAB) have been selected for membership in the Ivy Genomics-Based Medicine Project. The project is a national consortium of cutting-edge hospitals and academic centers working to improve treatment and survival for patients with a kind of malignant brain tumor called a glioma.

Farm-raised tilapia fish contains potentially dangerous fatty acid combination

"Farm-raised tilapia, one of the most highly consumed fish in America, has very low levels of beneficial omega-3 fatty acids and, perhaps worse, very high levels of omega-6 fatty acids, according to new research from Wake Forest University School of Medicine.

UV light therapy is as beneficial for darker skin as lighter skin

An analysis of more than 100 patients has confirmed for the first time that darker-skinned patients benefit as those with lighter skin when given light therapy for morphea and related diseases, UT Southwestern Medical Center researchers show.

Researchers detail types of genes necessary for brain

Researchers from Harvard Medical School and Brandeis University have successfully completed a full-genome RNAi screen in neurons, showing what types of genes are necessary for brain development. Details of the screen and its novel methodology are published July 4th in the open-access journal PLoS Genetics.

Novel ways to boost vaccination or natural defenses

Our bodies rely on the production of potent, or 'high affinity', antibodies to fight infection. The process is very complex, yet Sydney scientists have discovered that it hinges on a single molecule, a growth factor, without which it cannot function.

Prevalence of antimicrobial resistance among bacterial pathogens isolated from cattle in different European countries

Tests of antibiotic resistance in cattle have revealed stark variation across thirteen European countries. The results, published in BioMed Central's open-access journal Acta Veterinaria Scandinavica, show that major differences were apparent in the occurrence of resistance between countries and between the different antimicrobial agents tested.

Discovery of molecule that kills kidney cancer cells

Kidney cancer patients generally have one option for beating their disease: surgery to remove the organ. But that could change, thanks to a new molecule found by Stanford University School of Medicine researchers that kills kidney cancer cells. Ideally, the researchers said, a drug created from this molecule would help fight the life-threatening disease while leaving patients' kidneys intact.
