Infants with Rare Genetic Disease Saved By Cord Blood Stem Cells

...egin to lose all cognitive and motor functions and die by the age of two, said the researchers. They are from Duke University Medical Center's Pediatric Blood and Marrow Transplant Program and The Clinical Center for the Study of Development & Learning at the University of North Carolina at Chapel Hi...

Gene keeps neural cells on correct developmental path

...es not work for REST because mice lacking the gene die before they are born. Embryonic stem cells provided a way for Mandel to get around this problem. Unexpectedly, they also revealed fundamental ways in which stem cells remain plastic. "This paper is like a whole story, beginning with the birth of a n...

Chimp genome reveals a retroviral invasion

...ive cell, infection may spread, but viral DNA will die with the host. A retrovirus is called endogenous when it invades the germline and gets passed on to offspring. Because endogenous retroviruses can alter gene function and genome structure, they can influence the evolution of their host species. Over ...

Ebola virus: from wildlife to dogs

... However, most large primates, once infected, soon die of the disease. Their bodies then become a potential source of contamination for humans, but also for certain domestic animals. Ebola virus antibodies were detected in dogs exposed to the virus during the latest epidemics, which suggests that these a...

Some Brain Cells Change Channels

Newly discovered protein an important tool for sleeping sickness research

...ople in sub-Saharan Africa, a quarter of whom will die this year. Because the trypanosome has an exceptional genetic strategy for evading the human immune system and resisting treatment, the current treatment for this disease is melarsopal, an antiquated drug with terrible side effects, including death. ...

U. Iowa researchers improve Huntington's disease symptoms in mice

...p movement and coordination abnormalities and they die young. Aggregates, or clumps of protein, also develop in certain brain cells. Davidson explained that this mouse is very good for proof-of-principle experiments, allowing the researchers to ask a very pointed question ?can RNAi improve HD-like sympt...

Shark attack worries? Driving to the beach is more deadly

...s. McEachran goes on to note that far more people die each year - about 90 worldwide - from an allergic reaction to eating peanuts. Despite several attacks in Florida recently - one that killed a 14-year-old girl - shark attacks remain very rare when you put it all into perspective, McEachran believes....

$5.1 billion would save 6 million children

...s. If they don't, 16,000 children will continue to die each day as a result," said Jennifer Bryce, EdD, lead author of the study. This study follows a series of articles by Black, Bryce and their colleagues, published by The Lancet starting in June 2003, which examines the means to reduce global child m...

Study of energy and health in Africa focuses spotlight on charcoal and forest management

... 1.6 million people, primarily women and children, die prematurely each year worldwide (400,000 in sub-Saharan Africa) from respiratory diseases caused by the pollution from such fires, according to previous studies by the researchers. The current study, published in the April 1 issue of the journal Sci...

Cancer related gene p53 not regulated as indicated by previous tissue culture research

...feared that the mice might not be viable and would die during early embryonic development," says Krummel. More detailed investigations revealed that the altered p53 protein still binds to Mdm2, one of the negative regulators of p53 that facilitate its degradation. When p53 is activated by DNA damage th...

Malaria mechanism revealed

...f red blood cells called glycophorin A. Merozoites die if they do not invade red blood cells soon after their release (from liver cells) into the bloodstream. Thus, the binding of EBA-175 to glycophorin A is a prominent target for the development of therapies to control malaria. To explore the molecular...

Immune system's distress signal tells bacteria when to strike back

...tients with widespread Pseudomonas infection often die within a few days. Alverdy and colleagues were able to pinpoint key early steps of this lethal process. The transformation starts when a weakened host tries to boost its defenses against any possible invasion. The host's T cells release chemical sig...
