Neural stem cells transplanted into tumor-bearing rats can hinder tumor cell growth and prolife-ration; however, the mechanism remains unclear. Abnormal activation of the Ras/Raf/Mek/Erk signaling cascade plays an important role in glioma. Inhibition of this aberrant activity could effectively hinder glioma cell proliferation and promote cell apoptosis. To investigate the mechanism of glioblastoma treatment by neural stem cell trans-plantation with respect to the Ras/Raf/Mek/Erk pathway, Hua...

Researchers from Tubingen resolve how a plant steroid hormone makes plants grow If one wants to better understand how plants grow, one must analyze the chemistry of life in its molecular detail. Michael Hothorn from the Friedrich-Miescher-Laboratory of the Max Planck Society in Tübingen and his team are doing just that. Their latest work now reveals that a plant membrane receptor requires a helper protein to sense a growth-promoting steroid hormone and to transduce this signal across the...

Study could help yield new drugs for brain disorders Johns Hopkins biophysicists have discovered that full activation of a protein ensemble essential for communication between nerve cells in the brain and spinal cord requires a lot of organized back-and-forth motion of some of the ensemble's segments. Their research, they say, may reveal multiple sites within the protein ensemble that could be used as drug targets to normalize its activity in such neurological disorders as epilepsy,...

3D Structure Of Key Drug Target For Diabetes Found
2013-07-18 08:27:10

Scripps Research Institute An international team led by scientists at The Scripps Research Institute (TSRI) has determined and analyzed the three-dimensional atomic structure of the human glucagon receptor. The receptor, found mainly on liver and kidney cells, helps regulate glucose levels in the bloodstream and is the target of potential therapeutic agents for type 2 diabetes. "Our data should change the current view of how drugs are designed with this and related receptors," said TSRI...

Chlorinated BPA Is A Concern
2013-07-18 08:14:30

April Flowers for redOrbit.com - Your Universe Online Bisphenol A (BPA) has been a worry for scientists for years. It is known as an "endocrine disruptor," a substance that interferes with the body's hormone signaling system. BPA is found in everything from plastic drink bottles to the linings of food and drink cans to the thermal paper used for cash register receipts - it is even present in the urine of 92.6 percent of Americans over the age of six. BPA has also been associated with...

Brandeis scientists bring us a step closer to understanding how to control cancer cells without harming healthy ones The nasty side effects of radiation and chemotherapy are well known: fatigue, hair loss and nausea, to name a few. Cancer treatment can seem as harsh as the disease because it can't differentiate healthy cells from cancerous cells, killing both. But what if there were a way to control or stop the growth of cancer cells without harming other cells? Brandeis biologist...

baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
