Researchers Discover Achilles Heel Of The Plasmodium And Aim A Molecular Arrow To Destroy It
2014-03-12 15:01:18

Université de Genève The malaria parasite is particularly pernicious since it is built to develop resistance to treatments. The lack of new therapeutic approaches also contributes to the persistence of this global scourge. A study led by Didier Picard, professor at the Faculty of Sciences of the University of Geneva (UNIGE), Switzerland, describes a new class of molecules targeting the two problems at the same time. Using ultra sophisticated computerised modelling tools, the researchers...

Humans are often infected by parasites, sometimes even several species at a time. Such co-infections are more difficult to treat if the parasites interact with each other. An ecologist from the University of Zurich and his international team have compiled a list of the numerous possibilities as to how parasites can interact: They are most likely to do so indirectly via the food source they share. Over 1,400 species of parasites – viruses, bacteria, fungi, intestinal worms and protozoa...

Climate Change Allows Malaria To Reach New Heights

redOrbit Staff & Wire Reports - Your Universe Online Scientists from the London School of Hygiene & Tropical Medicine and the University of Michigan have discovered the first concrete evidence that the mosquito-borne disease malaria travels to higher elevations during warmer years and returns to lower altitudes when temperatures become cooler. In research appearing in the March 7 edition of Science, the study authors reviewed records from the highland regions of Colombia and...

An article featured in The Journal of Parasitology reviews the history of malaria research and examines the various approaches to that research. (PRWEB) March 03, 2014 Malaria has been around for millennia, and there are written references to it from early societies in China, India, Mesopotamia, Egypt, and Greece. Each year an estimated 500 million people are infected worldwide, making malaria a major public health concern. Some countries still experience malaria epidemics, which can also...

Barbara K. Kennedy, Penn State University 23 February 2014 — Two teams have independently discovered that a single regulatory protein acts as the master genetic switch that triggers the development of male and female sexual forms (termed gametocytes) of the malaria parasite, solving a long-standing mystery in parasite biology with important implications for human health. The protein, AP2-G, is necessary for activating a set of genes that initiate the development of gametocytes -- the...

Origin Of Deadly Human Malaria Parasite Linked To Primates In Africa

University of Pennsylvania School of Medicine An international team of scientists has traced the origin of Plasmodium vivax, the second-worst malaria parasite of humans, to Africa, according to a study published this week in Nature Communications. Until recently, the closest genetic relatives of human P. vivax were found only in Asian macaques, leading researchers to believe that P. vivax originated in Asia. The study, led by researchers from the Perelman School of Medicine at the...

School-based intermittent screening and treatment programs for malaria may be unsuccessful in low to moderate transmission areas A school-based intermittent screening and treatment program for malaria in rural coastal Kenya had no benefits on the health and education of school children, according to a study by international researchers published in this week's PLOS Medicine. The study, led by Katherine Halliday and Simon Brooker from the London School of Hygiene & Tropical Medicine,...

A newly identified protein and other proteins it interacts with could become effective targets for new drugs to control the parasite that cause toxoplasmosis, researchers led by investigators at Indiana University School of Medicine have reported. The discovery could also open new research pathways for treatments for malaria. The researchers determined that the protein, an enzyme called GCN5b, is necessary for the Toxoplasma parasite to replicate, so interfering with its activities...

Scientists have taken an important step towards new malaria treatments by identifying a way to stop malaria parasites from multiplying. In a study published in Nature Chemistry, they show that blocking the activity of an enzyme called NMT in the most common malaria parasite prevents mice from showing symptoms and extends their lifespan. The team are working to design molecules that target NMT more potently, and hope to start clinical trials of potential treatments within four years. A...

Chemical Modification In Human Malaria Parasite DNA Discovered

University of California - Riverside Findings by UC Riverside researchers could help build a new drug to kill the deadly parasite that is becoming resistant to existing drugs Say "malaria" and most people think "mosquito," but the buzzing, biting insect is merely the messenger, delivering the Plasmodium parasites that sickened more than 200 million people globally in 2010 and killed about 660,000. Worse, the parasite is showing resistance to artemisinin, the most effective drug for...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
