Their finding challenges the widely-accepted theory that Plasmodium falciparum, which causes the most lethal form of malaria, is the only malaria parasite capable of driving genome evolution in humans. The study was published today in the journal PLOS Medicine. Professor Ivo Mueller from the Walter and Eliza Hall Institute and Barcelona Centre for International Health Research (CRESIB) led the study, with colleagues from the Papua New Guinea Institute of Medical Research, Centre of Global...

Interactions Between Malaria Parasite and HIV Demonstrated With Novel Technique
2012-08-16 08:19:05

The World Health Organization estimates that in 2011 there were 216 million cases of malaria and 34.2 million people living with HIV. These diseases particularly afflict sub-Saharan Africa, where large incidence of co-infection result in high mortality rates. Yet, in spite of this global pandemic, interactions between the parasite that causes malaria, Plasmodium falciparum, and HIV-1 are poorly understood. However, a new video article in JoVE, the Journal of Visualized Experiments, that...

Researchers at Duke University Medical Center may finally have discovered why people with sickle cell disease get milder cases of malaria than individuals who have normal red blood cells. In a finding that has eluded scientists for years, Duke researchers discovered that genetic material in red blood cells may help alter parasite activity via a novel mechanism that alters parasite gene regulation. "One of the most interesting findings in our study is that the human microRNA (very small...

Sequenced Malaria Genome Provides Benefits, Difficulties In Finding A Cure
2012-08-06 11:45:07

Brett Smith for redOrbit.com - Your Universe Online After sequencing the genome of several malaria-related parasites, scientists found that the protozoans responsible for the deadly disease are very genetically diverse and therefore difficult to eradicate, according to their report published this week in the journal Nature Genetics. While the genomes of the four sequenced strains of Plasmodium vivax, a parasite that infects about 100 million people each year, indicated that...

The deadliest form of malaria is caused the protozoan Plasmodium falciparum. During its life-cycle in human blood, the parasite P. falciparum expresses unique proteins on the surface on infected blood cells. Antibodies to these proteins are associated with protection from malaria, however, the identity of surface protein(s) that elicit the strongest immune response is unknown. Dr. James Beeson and colleagues at the Walter and Eliza Hall Institute of Medical Research in Victoria, Australia...

Research: Overdiagnosis and mistreatment of malaria among febrile patients at primary healthcare level in Afghanistan: observational study Substantial overdiagnosis and mistreatment of malaria is evident in south and central Asia, warns a study published on bmj.com today. With more than two billion people at risk of malaria in this part of Asia — larger than that of Africa - this is a major public health problem which needs to be confronted, say the authors. Malaria remains one...

Can Genetics Prevent The Transmission Of Malaria?

redOrbit Staff & Wire Reports - Your Universe Online Malaria kills more than 800,000 people worldwide every year and many of those victims are children. Researchers are now reporting that they have genetically modified a bacterium commonly found in the mosquitos mid gut and found that the parasite that causes malaria in people does not survive in mosquitoes carrying the modified bacterium. The researchers, from the Johns Hopkins Malaria Research Institute, modified the bacterium...


Word of the Day
toccata
  • In music, a work for a keyboard-instrument, like the pianoforte or organ, originally intended to utilize and display varieties of touch: but the term has been extended so as to include many irregular works, similar to the prelude, the fantasia, and the improvisation.
This word is Italian in origin, coming from the feminine past participle of 'toccare,' to touch.
