Nanotubes inspire new technique for healing broken bones

...earch is particularly notable in the sense that it points the way to a possible new direction for carbon nanotube applications, in the medical treatment of broken bones," says Leonard Interrante, Ph.D., editor of Chemistry of Materials and a professor in the department of chemistry and chemical biology at R...

Researchers discover how tumor suppressor gene works

... melanoma and other human cancers works. The study points the way to treatments based on the function of the gene. The researchers, led by Zigang Dong, director of the university's Hormel Institute in Austin, Minn., have applied for a patent on one such treatment. The work will be published online July 10 i...

Unweaving amyloid fibers to solve prion puzzles

...r. He found that each prion molecule had only two points at which they connected to other prion molecules. One point he called the "head," the other the "tail." The head of one prion would only interact with the head of another prion, and likewise with tails. Remarkably, the same prion from the same yeast ...

The primary points of the AACR position on stem cell biology are: # Human stem cell research will elucidate critical aspects of cell growth and differentiation that are altered during the formation and growth of tumors. # Research on tissue-specific stem cells from a...

Sleeping beauty plays a significant role in identifying cancer genes

... major leap forward in understanding cancer's weak points and thus lead to better treatments." According to Largaespada, "About 300 human cancer-related genes have thus far been reported in the scientific literature. Most of those identified are involved in cancers of the blood system. So, there are likely...

AIDS expert says global strategy needed to combat feminization of HIV/AIDS

...haned, women deserve a separate strategy. He also points out that medical research suggests hormonal and developmental factors place young women at greater risk than men for contracting the virus when exposed to it. 60 percent of people living with HIV in sub-Saharan Africa, are female, Quinn says, and in...

Mayan stingless bee keeping: Going, going, gone?

... where no one inherits their knowledge of the fine points of meliponiculture, specifically, how to propagate bees by dividing nests. Earlier this year, Rogel Villanueva-Gutierrez, first author of the paper, with Stephen Buchmann, Arthur James Donovan and Roubik published an amply illustrated handbook, in Sp...

Survival of heart patients on beta-blockers varies greatly with genetic variation

...esult uncertain. The beta-2 gene commonly has two points of sequence variation within the human population--for most of the population, the gene's coding sequence will be identical from person to person at all other points. Thirty-nine percent of the population possess a set of beta-2 genes with a C base a...

As the joining points between muscles and bones have survived unaltered across hundreds of millions of year researchers can also start to map cell territories into fossils. For the first time the research team have been able to trace what happened to a major shoulder bone...

Arthritis: What Wnt wrong?
