BF STEM tomography allows to visualize fine details of cell structure

Scientists in the National Institute of Biomedical Imaging and Bioengineering (NIBIB) Laboratory of Bioengineering and Physical Science have developed a new technique that allows researchers to visualize fine details of cell structure three-dimensionally in thick sections, thus providing greater insight into how cells are organized and how they function. The work is described in a report published online this week in Nature Methods.

Eye disease medication lowers death rate among Ethiopian children

Children in Ethiopia who received the antibiotic azithromycin as a method for controlling the contagious eye disease trachoma had a lower odds of death compared to children who did not receive the antibiotic, according to a study in the September 2 issue of JAMA.

Evidence of Malaria origins, could lead to vaccine development

"Malaria may have jumped to humans from chimpanzees much as AIDS did, U.S. researchers reported on Monday in a [Proceedings of the National Academy of Sciences] study they hope could help in developing a vaccine against the infection," Reuters reports.

Scientists discover original source of malignant malaria

Researchers have identified what they believe is the original source of malignant malaria: a parasite found in chimpanzees in equatorial Africa.

Malaria vaccine in the pipeline

Australian scientists have developed the first genetically-engineered malaria vaccine and the vaccine will be trialled in humans early next year.

World's first genetically-modified strain of malaria parasite

Walter and Eliza Hall Institute scientists have created a weakened strain of the malaria parasite that will be used as a live vaccine against the disease. The vaccine, developed in collaboration with researchers from the US, Japan and Canada, will be trialled in humans from early next year.

Camera-phone uses blood, saliva samples to diagnose disease

Researchers at the University of California, Berkeley, have developed a "prototype camera-phone mounted with a microscope" that can "magnify and photograph blood or saliva samples" for diagnosing diseases, the Canadian Press/Google.com reports.

Special pathway makes bacteria vulnerable - new target for tailored antibiotics

More and more strains of bacteria are developing resistance to previously life-saving antibiotics. Researchers at TUM, the Technische Universitaet Muenchen, have shed light on a metabolic step that appears in many aggressive microorganisms -- such as tuberculosis and malaria pathogens -- and that may provide a promising target for a new class of antibiotics. The researchers present their results in the chemistry journal Angewandte Chemie.

Variation of natural compound cures malaria in mice

Approximately 350 million to 500 million cases of malaria are diagnosed each year mostly in sub-Saharan Africa. While medications to prevent and treat malaria do exist, the demand for new treatments is on the rise, in part, because malaria parasites have developed a resistance to existing medications.

Simple blood test proves powerful ally in the fight against malaria

Scientists at the Swedish medical university Karolinska Institutet have shown that rapid diagnostic tests (RDT) for malaria infection can provide valuable support for healthcare in low and mid-income countries in the fight against the disease.

Trial of unique malaria vaccine candidate to begin

In a move that highlights the strength of public-private collaboration in tackling international health challenges, the Maryland-based company Sanaria Inc., with support from the PATH Malaria Vaccine Initiative (MVI), has initiated a Phase 1 clinical trial - the first tests in adult volunteers - of its unique malaria vaccine candidate. Unlike other malaria vaccine candidates, Sanaria's approach deploys a weakened form of the whole malaria parasite harvested from irradiated mosquitoes instead of small portions of the parasite.

Researchers create chemicals that kill the most deadly malaria-causing parasite

Researchers at the University of Leeds have developed chemicals which kill the most deadly malaria-causing parasite, Plasmodium falciparum - including those resistant to existing drugs.

Discovery of variations in resistance to sulfadoxine across Africa

Researchers have discovered that malaria parasites in east and west Africa carry different resistance mutations, which suggests that the effectiveness of sulfadoxine as an antimalarial drug may vary across Africa.

Locking parasites in host cell could be new way to fight malaria

Researchers at the University of Pennsylvania have discovered that parasites hijack host-cell proteins to ensure their survival and proliferation, suggesting new ways to control the diseases they cause.

NEJM Letters respond to recent studies on malaria vaccines, treatments

The New England Journal of Medicine in its March 19 issue featured a letter to the editor written in response to a study published in its Dec. 11 issue reporting the results of the RTS,S/AS01E malaria vaccine trial.

Malaria immunity trigger found for multiple mosquito species

Researchers at the Johns Hopkins Bloomberg School of Public Health have for the first time identified a molecular pathway that triggers an immune response in multiple mosquito species capable of stopping the development of Plasmodium falciparum -the parasite that causes malaria in humans.

15 Mar 2009

Discovery of new mechanism the malaria parasite uses to enter human red blood cells

Virginia Commonwealth University Life Sciences researchers have discovered a new mechanism the malaria parasite uses to enter human red blood cells, which could lead to the development of a vaccine cocktail to fight the mosquito-borne disease.

Synthetic biology extends anti-malaria drug artemisinin's effectiveness

In addition to providing a simple and much less expensive means of making artemisinin, the most powerful anti-malaria drug in use today, synthetic biology can also help to extend the effectiveness of this drug.

Combo malaria treatment dihydroartemisinin and piperaquine shows promise

The results of two new large scale trials show that the combination of dihydroartemisinin and piperaquine (DHA+PQP) not only is effective against uncomplicated malaria in a way which is comparable to other artemisinin-based combination therapies (ACTs), but it also protects patients against new infections for at least two months after treatment.
