Fibril Shape Is The Basis Of Prion Strains And Cross-species Prion Infection

New research on prions, the infectious proteins behind "mad cow" disease and Creutzfeld-Jakob disease in humans, suggests that the ability of prions in one species to infect other species depends on the shape of the toxic threadlike fibers produced by the prion. Two studies on the topic appear in the 8 April issue of the journal Cell. Although research suggests that prions from one specie...

DNA constraints control structure of attached macromolecules

A new method for manipulating macromolecules has been developed by researchers at the University of Illinois at Urbana-Champaign. The technique uses double-stranded DNA to direct the behavior of other molecules. In previous DNA nanotechnology efforts, duplex DNA has been used as a static lattice to construct geometrical objects in three dimensions. Instead of manipulating DNA alone into s...

Experimental vaccine protects lab animals against several strains of H5N1

Nations are preparing to stockpile vaccines against H5N1, the strain of influenza virus that experts fear could cause the next flu pandemic. But will these vaccines remain effective as the virus mutates? Researchers present good news in the July 15 issue of The Journal of Infectious Diseases, now available online. Elena Govorkova, MD, PhD, Robert G. Webster, PhD, and coworkers at St. Jude...

Less virulent strains of avian influenza can infect humans

In findings with implications for pandemic influenza, a new study reports for the first time that a less-virulent strain of avian influenza virus can spread from poultry to humans. The research appears in the October 1 issue of The Journal of Infectious Diseases, now available online. Crossing the species barrier is an important step in the development of a flu virus with pandemic potenti...

Emerging staph strains found to be increasingly deadly and deceptive

A study of how the immune system reacts to strains of antibiotic-resistant Staphylococcus aureus bacteria--emerging strains that sicken otherwise healthy people, or so-called "community-acquired" infections--has shown for the first time that these strains are more deadly and better at evading human immune defenses than more common S. aureus strains that originate in hospitals and other health-car...

African HIV strains more resistant to anti HIV drugs

Genetic variations in the HIV strains in Africa make it more difficult for the anti AIDS drugs to act on them according to researchers. This however does not mean that these drugs will be powerless against the virus but these drugs find it difficult to latch on to the protease, which is an enzyme useful in the replication of the virus inside the body. If the drug attaches itself to the p...

E. coli strains resistant to a common antibiotic

Food contaminated with a strain of drug-resistant E. coli has emerged as a possible new source of urinary tract infections. E. coli is a normal inhabitant of the digestive tract that can cause both intestinal upsets and urinary infections. But while E. coli from bad food is a frequent cause of diarrhoea and other digestive miseries, urinary tract infections were thought until now to result mostly...

Hormone restrains appetite in man

According to reasearchers, a hormone is released into the blood after a meal, restrain the appetite if given by injection and might be supportive in treating obesity. The reason for feeling full after a meal, that the intestines release a hormone called PYY3-36 //which acts on the brain to produce a feeling of satiety. Researchers at Imperial College, London, now report on the first human trial...
