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.

Hospitalized patients with anemia may not always benefit from transfusion

University of Kentucky researchers, including lead author Samy Selim of the Division of Cardiovascular Medicine and the Saha Cardiovascular Research Center, have recently published a paper suggesting that transfusion may not always be the best treatment for hospitalized patients with anemia.

Researchers identify new enzyme function that may protect against anemia

Researchers at St. Michael's Hospital have discovered a new function for an enzyme that may protect against organ injury and death from anemia.

Researchers use patient's own stem cells to correct genetic alteration that causes SCD

Using a patient's own stem cells, researchers at Johns Hopkins have corrected the genetic alteration that causes sickle cell disease (SCD), a painful, disabling inherited blood disorder that affects mostly African-Americans. The corrected stem cells were coaxed into immature red blood cells in a test tube that then turned on a normal version of the gene.

Researchers validate two parasite enzymes as potential anti-malarial drug targets

Researchers at the Perelman School of Medicine at the University of Pennsylvania, Monash University, and Virginia Tech have used a set of novel inhibitors to analyze how the malaria parasite, Plasmodium falciparum, uses enzymes to chew up human hemoglobin from host red blood cells as a food source.

Close link between SF3B1 mutation and specific feature of myelodysplastic syndromes

Geneticists have discovered that a gene involved in the modification of ribonucleic acid (RNA) is mutated in a significant proportion of people with a collection of blood cancers called myelodysplastic syndromes.

Researchers identify frequent SF3B1 gene mutation in myelodysplasia

A genomic study of chronic blood cancer - a precursor to leukaemia - has discovered gene mutations that could enable diagnosis using only a blood test, avoiding the need for an invasive and painful bone marrow biopsy.

Psychological stress of racial discrimination may contribute to health disparities

The consequences of psychological stress, resulting from racial discrimination, may contribute to racial health disparities in conditions such as cardiovascular disease, diabetes and other age-associated diseases.

First effective blood-stage vaccine against malaria

Scientists have identified the first effective blood-stage malaria vaccine, according to a New England Journal of Medicine study from University of Maryland School of Medicine researchers, in collaboration with the University of Bamako in Mali, West Africa, and other partners.

Acceleron commences ACE-536 Phase 1 clinical trial in anemia

Acceleron Pharma, Inc., a biopharmaceutical company developing protein therapeutics for cancer and orphan diseases today announced that it has initiated a Phase 1 clinical study of ACE-536.

New blood test could help identify babies at risk of sickle cell disease

A new blood test is being developed by researchers in Cambridge and Oxford, which, for the first time, could help identify babies at risk of a severe form of sickle cell disease, allowing immediate and more intensive treatment to be given, thanks to a grant from children's charity Action Medical Research.

Researchers inject cultured red blood cells created from HSCs into human donor

For the first time, researchers have successfully injected cultured red blood cells (cRBCs) created from human hematopoietic stem cells (HSCs) into a human donor, according to study results published today in Blood, the Journal of the American Society of Hematology.

Shriners Hospitals for Children uses Masimo SpHb during selected surgeries

The healthcare professionals at Shriners Hospitals for Children - Honolulu, which perform hundreds of orthopaedic surgeries on children each year, are using the latest in medical technology from Masimo to noninvasively monitor patient blood levels during selected surgeries.

High risk of serious complications or death in children with SP-HUS

Hemolytic uremic syndrome (HUS) caused by infection with pneumococcal bacteria leads to severe illness—with a high rate of irreversible kidney damage—in infants and young children, reports a study in the September issue of The Pediatric Infectious Disease Journal.

Hurricane Irene affects supplies of several blood types

New York Blood Center (NYBC), serving more than 20 million people in New York City, Long Island, the Hudson Valley, and New Jersey, is following the emergency declarations of Mayor Bloomberg and other tri-state public officials with an emergency appeal for blood donors. The supply of several blood types, including O-negative ("universal donor") blood, which is normally maintained at the three-to-five-day inventory level, has dropped below the two-day minimum level.

Leucine may help people burn fat during periods of food restriction

Research on Mt. Everest climbers is adding to the evidence that an amino acid called leucine - found in foods, dietary supplements, energy bars and other products - may help people burn fat during periods of food restriction, such as climbing at high altitude, while keeping their muscle tissue.
