New system could measure mechanical properties of living cells

Researchers are making progress in developing a system that measures the mechanical properties of living cells, a technology that could be used to diagnose human disease and better understand biological processes.

MedUni Vienna researchers discover important regulators in development of stem cells

A team of researchers at the MedUni Vienna's Institute of Medical Genetics has discovered that two genes (TSC/Tuberin and PRAS40) are extremely important regulators in the development of stem cells: if these genes are switched off, the stem cells do not develop but instead die a programmed cell death.

Scientists solve mystery behind why people with defective hemoglobin do not contract malaria

Why do people with a hereditary mutation of the red blood pigment hemoglobin not contract severe malaria? Scientists in the group headed by Prof. Michael Lanzer of the Department of Infectious Diseases at Heidelberg University Hospital have now solved this mystery.

Dendrimers can capture circulating tumor cells in blood by biomimicry

The removal of rare tumor cells circulating in the blood might be possible with the use of biomolecules bound to dendrimers, highly branched synthetic polymers, which could efficiently sift and capture the diseased cells, according to new research at the University of Illinois at Chicago.

Scientists discover family of chemical compounds that could prevent malaria

A international team led by scientists from the Genomics Institute of the Novartis Research Foundation (GNF) and The Scripps Research Institute has discovered a family of chemical compounds that could lead to a new generation of antimalarial drugs capable of not only alleviating symptoms but also preventing the deadly disease.

Stroke incidence related to blood type: Study

A latest study reveals that the risk for stroke maybe tied to blood type, with men and women with type AB and women with type B facing greater risk than people with type O. Researchers add that this study does not prove the link but it agrees with other studies that have tied A, B, and AB to heart attack and to blood clots in the legs. And type O has been linked to a heightened risk for bleeding, which implies less chance of the clots that are responsible for most strokes.

Researchers identify hepcidin hormone as potential target for atherosclerosis

Researchers at Emory University School of Medicine have identified hepcidin, a hormone that regulates iron levels in the body, as a potential target for treating atherosclerosis.

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.

HemaCare reports third quarter revenue of $4.0M from continuing operations

HemaCare Corporation announced today that the Company generated 2011 third quarter revenue of $4.0 million from continuing operations and net income of $512,000 or $0.05/share, including net income from discontinued operations of $1,090,000.

Penn study on gut cell regeneration reconciles long-standing research controversy

The lining of the intestine regenerates itself every few days as compared to say red blood cells that turn over every four months. The cells that help to absorb food and liquid that humans consume are constantly being produced. The various cell types that do this come from stem cells that reside deep in the inner recesses of the accordion-like folds of the intestines, called villi and crypts.

British researchers discover receptor necessary for malaria parasite to invade red blood cells, offering new vaccine hope

Researchers from the Wellcome Trust Sanger Institute in the U.K. have "made a critical discovery about the way the most deadly species of malaria parasite invades human red blood cells," Reuters reports.

Universally effective malaria vaccine on the horizon

Scientists are excited with a new breakthrough in development of an effective vaccine against malaria. The latest study finds how malaria acts and how the vaccine would be able to protect individuals from malaria.

Study reveals need for defining optimal amount of iron in infant formula

A 10-year follow-up study examining iron-fortified vs. low-iron infant formula suggests that infants with high hemoglobin levels who received iron fortified infant formula have poorer long-term developmental outcomes.

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.

NIH-funded project to discover biomarkers for type 2 diabetes

Arizona State University will lead a four-year, $5 million expanded initiative sponsored by the National Institutes of Health to discover proteins, or biomarkers, to help predict cardiovascular disease and to assess potential new treatments in people with type 2 diabetes.

Light-cell interaction and Born approximation rule can help detect misshapen red blood cells

Misshapen red blood cells are a sign of serious illnesses, such as malaria and sickle cell anemia. Until recently, the only way to assess whether a person's RBCs were the correct shape was to look at them individually under a microscope - a time-consuming process for pathologists.

First results from phase 3 malaria vaccine candidate trial

First results from a large-scale Phase III trial of RTS,S, published online today in the New England Journal of Medicine (NEJM), show the malaria vaccine candidate to provide young African children with significant protection against clinical and severe malaria with an acceptable safety and tolerability profile. The results were announced today at the Malaria Forum hosted by the Bill & Melinda Gates Foundation in Seattle, Washington.

BCL11A protein might serve as potential target for sickle cell disease

Flipping a single molecular switch can reverse illness in a model of sickle cell disease, according to a study by researchers at Children's Hospital Boston and Dana-Farber Cancer Institute. When turned off, the switch, a protein called BCL11A, allows the body to manufacture red blood cells with an alternate form of hemoglobin unaffected by the mutation that causes the disease.

Entirely new platform to assist in developing antimalarial drugs

Malaria has been one of the world's biggest killers for as long as records have been kept. With resistance to existing antimalarial drugs on the rise, there is a renewed push to find different ways to fight it. Two University of Houston (UH) engineers have stepped up to the plate to answer the call.

Potential new protein target for sickle cell disease

National Institutes of Health-funded scientists have corrected sickle cell disease in adult laboratory mice by activating production of a special blood component normally produced before, but not after, birth.
