Potential drug target for malaria

Researchers have identified an enzyme crucial to the malaria parasite's invasion of red blood cells, according to a study in the open-access journal, PLoS Pathogens.

American physicians may be too liberal in their use of blood transfusions

In an analysis of some 24,000 patient records, the researchers found that Americans rushed to the hospital with heart attack symptoms have significantly higher rates of bleeding and transfusions after treatment than similar patients throughout the world.

Gene doping is a real danger - but anti-doping science is making progress

Gene therapy research has reached a critical phase. Already practised on humans as part of strictly controlled experiments, gene therapy promises to become a widely available form of treatment for injury and disease.

Fundamental insight about protein evolution

While searching for new targets for malaria drugs and vaccines, a team including a Howard Hughes Medical Institute (HHMI) medical student fellow reached a fundamental insight about evolution: different species make use of similar sets of proteins in different ways.

New method to find deadly malaria parasite

Researchers at UCSD have discovered that the single-cell parasite responsible for an estimated 1 million deaths per year worldwide from malaria has protein "wiring" that differs markedly from the cellular circuitry of other higher organisms

Regular use of ibuprofen may increase gastrointestinal bleeding

People who take high doses of ibuprofen on a regular basis are three times more likely to experience gastrointestinal (GI) bleeding than those who do not take painkillers.

Gold nanorods injected into the bloodstream may be used to develop an advanced medical imaging tool

Researchers at Purdue University have taken a step toward developing a new type of ultra-sensitive medical imaging technique that works by shining a laser through the skin to detect tiny gold nanorods injected into the bloodstream.

Elderly people with the lowest and highest hemoglobin concentrations are at increased risk of death

Increasing evidence indicates that anemia is common in the elderly population, but few studies have assessed the association of anemia with clinical outcomes, such as illness and death, according to background information in the article.

New model important step toward understanding the molecular basis of cell membrane mechanics

A human red blood cell is a dimpled ballerina, ceaselessly spinning, tumbling, bending, and squeezing through openings narrower than its width to dispense life-giving oxygen to every corner of the body.

Testosterone may improve women's sex lives after menopause

The addition of testosterone to hormone therapy in women after menopause enhances their sexual function. However, it may also reduce HDL cholesterol (the "good" cholesterol) in women, according to a systematic review of current evidence.

New device offers potential for accurate and reliable monitoring of brain oxygenation during cardiac surgeries

A new device that uses near-infrared light to non-invasively monitor the oxygenation of the brain during surgery appears to be a promising alternative to the more invasive techniques currently in use, according to a new study by Duke University Medical Center anesthesiologists.

Nitric oxide may help sickle cell patients

Inhaling a small dose of nitric oxide gas may one day help sickle cell patients avoid pain crises and live healthier lives, researchers say.

Researchers learn to rapidly rebuild immunity in immune-suppressed cancer patients

Patients with multiple myeloma suffer from a malignant proliferation of plasma cells in their bone marrow. The standard treatment for this form of cancer is high-dose chemotherapy and transplantation of one's own blood-producing adult stem cells; however, this aggressive treatment wipes out the mature immune-system cells of patients – leaving them vulnerable to infection.

Hepatitis C linked to illegal blood donation in China

Research in a rural province of central China has documented that illegal blood donation practices led to high hepatitis C virus (HCV) infection rates in blood and plasma donors during the 1980s and early 1990s, and that failure to screen for HCV in transfusion recipients increased their risk of infection as well

Researchers reveal basis for hereditary coproporphyria

A research team led by scientists at The University of Texas Medical School at Houston has determined the structure of an enzyme that when defective causes an inherited disease that afflicts sufferers with severe abdominal pain, psychiatric symptoms, skin fragility, and light sensitivity.

Lack of oxygen in body tissues creates a defect of red blood cells that further exacerbates the condition by constricting blood vessels in the lung

What's more, the team demonstrated through studies in people and animals that inhalation of a 'souped up' form of nitric oxide, which targets red blood cells, reverses the blood abnormality to restore normal lung pressure.

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.
