A new study finds that a gene which plays an important role in immune function, known as toll-like receptor 4 (TLR4), may also play a critical role in suppressing chronic lung inflammation and tumor development in mice.
"We know that chronic inflammation predisposes people to many types of cancer," says NIH Director Elias Zerhouni, M.D. "By using this new information we may be able to suppress chronic inflammation and reduce our Nations cancer burden."
In the December 7, 2005 issue of the Journal of the National Cancer Institute, researchers at the National Institute of Environmental Health Sciences (NIEHS), a part of the National Institutes of Health, report that mice prone to lung cancer that had TLR4 removed or altered had 60 percent more tumors than mice that had intact receptors, illustrating a new protective role for this gene. There were no differences in overall tumor size or structure between the mice. TLR4 is part of what immunologists refer to as the "innate immune system" which acts as the bodys first line of defense against harmful substances.

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.
The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
