Researchers gain insights into how malaria pathogen destroys the cells in which it resides

By specially tagging the outer and inner membranes of red blood cells infected with the malaria parasite and tracking the cellular changes that precede the cell bursting event that disperses parasites to other blood cells, a group of researchers has deepened our understanding of how the malaria pathogen destroys the cells in which it resides.

Researchers determine the sequence in which the malaria parasite disperses from the red blood cells it infects

Researchers at the National Institute of Child Health and Human Development have determined the sequence in which the malaria parasite disperses from the red blood cells it infects. The National Institute of Child Health and Human Development is one of the Institutes comprising the National Institutes of Health.

Collaborators seek parasite invasion blockers

A malaria research team, including WEHI Structural Biologist, Professor Ray Norton, has received a US$1 million grant from the US National Institutes of Health to develop more effective malaria treatments.

Parasite could help prevent asthma

Asthma in Britain has reached epidemic proportions and the country now has one of the highest numbers of sufferers of the allergy in the world; in Ireland alone it is reported that as many as 30% of all schoolchildren have symptoms of the disease.

Can a new combination treatment prevent a secondary stroke in children with sickle cell anemia?

St. Jude Children’s Research Hospital will lead a national Phase III clinical trial to investigate whether a new combination treatment can prevent a secondary stroke in children with sickle cell anemia (SCA) and eliminate the need for nightly injections with a drug that reduces iron overload in these patients.

Three-dimensional molecular structure of a promising malaria-vaccine component

An international team of scientists that includes a researcher from the U.S. Department of Energy's Brookhaven National Laboratory has determined the three-dimensional molecular structure of a promising malaria-vaccine component.

Molecular missing link between fasting and acute attacks of porphyria

A team of researchers has discovered a molecular missing link that helps explain why fasting brings on acute attacks of the genetic disease hepatic porphyria, according to a new report in the 26 August issue of the journal Cell.

Malaria researchers find the parasite's housebreaking tool

Plasmodium falciparum, the most lethal malaria parasite, is a housebreaking villain of the red blood cell world. Like a burglar searching for a way in to his targeted premises, the parasite explores a variety of potential entry points to invade the red blood cells of its human victims. When a weak point is found, the intrusion proceeds.

Ways to avoid hazards of heart bypass under study

The heart-lung bypass machine that stills the heart while surgeons bypass an adult’s clogged arteries or repair a baby’s malformed heart can also trigger a potentially deadly inflammatory response.

Unique blood test detects iron deficiency in infants earlier

A unique blood test detects iron deficiency in infants earlier and more accurately than the commonly used hemoglobin screening test, according to a study in the August 24/31 issue of the Journal of the American Medical Association.

Low hemoglobin levels are a predictor of increased risk of death among heart failure patients

Hemoglobin (Hgb) is the major substance in red blood cells, and its level indicates the blood's ability to carry oxygen throughout the body. Studies have shown that low hemoglobin, which may result in anemia, is more common among patients with heart failure than it is among people in the general population.

Low levels of folate linked to lower birth rates

Mothers-to-be with lower levels of the vitamin folate in their body during early pregnancy are more likely to have babies with lower, or less healthy, birth weights, a study has revealed.

Valuable clues for rational antimalarial drug design and vaccine development

By determining the molecular structure of a protein that enables malaria parasites to invade red blood cells, researchers have uncovered valuable clues for rational antimalarial drug design and vaccine development. The findings are reported in the July 29 issue of the journal Cell.

New molecular insights may one day lead to opportunities to stave off old age

Delving deep into the molecular subtleties of a strain of mice engineered to age rapidly, scientists have found that an accumulation of genetic mutations prompts a cascade of programmed cell death that seems to underpin the aging process.

Research discovers new deadly link to sickle cell disease

A new study led by a researcher at Children's Hospital & Research Center at Oakland is the first to find that an amino acid deficiency in sickle cell disease is the result of hemolysis, a process where red blood cells rupture and release their contents into the blood stream. Low availability of the amino acid arginine is associated with lung disease and death in adult sickle cell patients.

Discovery of genes that impact the development and function of blood stem cells

Researchers at the University of Minnesota have identified for the first time a group of genes that impact the development and function of blood stem cells, a discovery that brings researchers a step closer to harnessing the power of stem cells for disease treatments.

Stem cells to solve blood shortage problems

The State Government of Victoria, Australia announced that Melbourne scientists at Monash University have developed a unique technology that can grow large numbers of blood cells from human embryonic stem cells.

Hydroxyurea may prevent complications such as organ damage and stunted growth in treatment of sickle cell disease

Treating babies who have sickle cell disease (SCD) with oral liquid hydroxyurea appears to prevent the onset of long-term complications triggered by this disease, according to results of a preliminary study by investigators at St. Jude Children's Research Hospital.

First clues as to why stem cells ignore stop signs in the cell cycle

Everyone knows that stem cells are controversial. Many people know that stem cells can grow into virtually any cell type found in the body, from a red blood cell to a muscle cell to a brain cell. But no one really knows why stem cells continue to divide and renew themselves long after the point where other cells stop dividing.
