...s a known risk factor for dementia, a neurological disorder most commonly caused by Alzheimer's disease. Changes in clinical measures of activity, such as walking and finger-tapping speeds, have been shown to occur at about the same time as memory changes leading to dementia. By detecting subtle activity chan...

Using a tool called RNA interference on cells in the laboratory, researchers successfully intercepted signals sent out by the rampant protein and prevented cell dama...

A large step forward in the fight against African sleeping sickness

... patient's death. African sleeping sickness is a disorder caused by the trypanosome parasite. The blood-sucking tsetse fly transmits the parasite from person to person. Once someone has been infected by the parasite, the person's body has great difficulty getting the infection under control, because the par...

Gene variation increases SIDS risk in African Americans

How can we protect patients with weakened immune systems from influenza?

...q.11.2 deletion syndrome, a congenital multisystem disorder that impairs the immune system. Children's Hospital is a world leader in studying and treating this syndrome. Three projects involving adults are led by researchers in the University of Pennsylvania Health System. Two projects involve cancer patient...

Removing DNA repair gene causes metabolic syndrome

...nt mouse's propensity for developing the metabolic disorder about two years ago. Their interest in NEIL1 was initiated by their efforts to clone and crystallize homologs to the Escherichia coli endonuclease VIII gene. E. coli endonuclease VIII is part of a pathway of enzymes involved in repairing DNA damaged ...

It's in the genes: Study opens door to new treatment of the blues

...ificant because it gives us an animal model of the disorder and opens up new areas of study." In the experiment, the researchers subjected mice to daily bouts of social threats and subordination by aggressive rodents and continuous sensory contact with the aggressors for 10 days. Afterward, the defeated mice...

Patients now surviving once-fatal immune disease

Individuals who have a rare genetic immune system disorder that prevents them from making antibodies nevertheless appear to be moderately healthy and lead productive lives, according to results of a study by investigators at St. Jude Children's Research Hospital. A report on this study appears in the current...
