MUHC scientists describe genetic resistance to rampant virus

...evolutionary arms race for millions of years in an attempt to overwhelm each other. Dr. Vidal and her team h...0 years studying CMV-resistant mouse strains in an attempt to describe the nature of their genetic resistance. "This research marks our second discovery of gen...

Mystery Blood Vessel Disorder Implicated In 'Mini' Strokes

...factors contribute to the syndrome. They will also attempt to replicate their MRI data in an autopsy study of patients who died with dolichoectasia. ### Article: "Intracranial Arterial Dolichoectasia and Small-Vessel Disease in Stroke Patients," by Fernando Pico, Julien Labreuche, Pierre-Jean Touboul, Didi...

Gene therapy promising for growing tooth-supporting bone

...tein-7 (BMP-7) to large bone defects in rats in an attempt to turn on the body's own bone growth mechanisms. The study showed that animals that got the BMP-7 treatment produced nearly 50 percent more supporting bone around dental implants than those receiving the conventional treatment. "This study represen...

DuPont's first biologically derived polymer receives global recognition

...products on oil resources. It will be another bold attempt in the innovative use of renewable resources. Crops and plants are becoming the most reliable backup power for the resource consumption of humans and will serve to further protect the environment." DuPontTM Sorona® offers unique properties to consum...

Norovirus, AIDS vaccine and Hepatitis Virus

...y. Developing a vaccine to protect against HIV in attempt to gain control of the AIDS pandemic is a top priority for researchers throughout the world. Extensive testing has been conducted with live vaccines to determine if immunization would be effective at prevention, but they are not suitable for human us...

Family trees of ancient bacteria reveal evolutionary moves

...tion is: Why?" said Blank. "My contribution is the attempt to find evolutionary explanations for these major changes. There were lots of evolutionary movements in Cyanobacteria at this time, and the bacteria were making an impact on the Earth's development. Geologists in the past have been relying on geologi...

Needling Chromosomes Reveals Cell Division Secret

...another at that time."What hadn’t been done was to attempt to separate chromatids todirectly determine whether they, in fact, are held together or not,"said Nicklas. "So, Leocadia set out to use micromanipulation todistinguish between visible separateness and physical separateness."To study chromatid adhesio...

Molecular machine may lead to new drugs to combat human diseases

... use the information gleaned from this study in an attempt to develop new drugs, Golden said. Introns were unknown until the late 1970s, and scientists are still investigating their function. Crystallization of the complex is one tool to determine their purpose. Two intron structures in different stages of...

U of M researcher examines newly emerging deadly disease

...n of activated protein C (i.e., drotrecogin) in an attempt to minimize purpuric skin injury and to slow the inflammatory cascade before irreparable tissue injury occurs. In addition, because toxic shock syndrome is mediated by superantigens, it is possible that intravenous immunoglobulin therapy may be indic...
