Researchers report that these new stem-like cells do not express the same genes as embryonic stem cells and induced pluripotent stem cells (iPSCs) do. That explains why they don't produce tumors when they grow in the laboratory, as the other stem cells do, and why they are stable, producing the kind of cells researchers want them to.Mon, 19 Nov 2012 15:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121119151314.htmBody may be able to 'coach' transplanted stem cells to differentiate appropriatelyhttp://www.sciencedaily.com/releases/2012/11/121119151308.htm Pluripotent stem cells are nature's double-edged sword.

However, that same developmental flexibility can lead to dangerous tumors called teratomas if the stem cells begin to differentiate out of control in the body.Mon, 19 Nov 2012 15:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121119151308.htmHow yeast protein breaks up amyloid fibrils and disordered protein clumpshttp://www.sciencedaily.com/releases/2012/11/121119151220.htm Hsp104, an enzyme from yeast, breaks up both amyloid fibrils and disordered clumps. For stable amyloid-type structures, Hsp104 needs all six of its subunits, which together make a hexamer, to pull the clumps apart. By contrast, for amorphous, non-amyloid clumps, Hsp104 required only one of its six subunits.Mon, 19 Nov 2012 15:12:12 ESThttp://www.sciencedaily.com/releases/2012/11/121119151220.htmExperimental drug improves memory in mice with multiple sclerosishttp://www.sciencedaily.com/releases/2012/11/121119151218.htm Researchers report the successful use of a form of MRI to identify what appears to be a key biochemical marker for cognitive impairment in the brains of people with multiple sclerosis (MS).

Researchers found that a shortage of the genetic factor KLF4, which regulates endothelial cells lining the interior of blood vessels, makes the lining more prone to the buildup of plaque and fat deposits. Further, the deficiency made the blood vessel more susceptible to clot formation.Mon, 19 Nov 2012 11:43:43 ESThttp://www.sciencedaily.com/releases/2012/11/121119114300.htm3-D light switch for the brain: Device may help treat Parkinson's, epilepsy; aid understanding of consciousnesshttp://www.sciencedaily.com/releases/2012/11/121119114249.htm A new tool for neuroscientists delivers a thousand pinpricks of light to individual neurons in the brain.

This condition in monkeys is similar to the inflammatory bowel diseases that affects up to 1.4 million Americans.Thu, 15 Nov 2012 17:20:20 ESThttp://www.sciencedaily.com/releases/2012/11/121115172030.htmVitamin D deficiency linked to type 1 diabeteshttp://www.sciencedaily.com/releases/2012/11/121115171332.htm A study has found a correlation between vitamin D3 serum levels and subsequent incidence of Type 1 diabetes. The six-year study of blood levels of nearly 2,000 individuals suggests a preventive role for vitamin D3 in this disease.Thu, 15 Nov 2012 17:13:13 ESThttp://www.sciencedaily.com/releases/2012/11/121115171332.htmNew injectable gels toughen up after entering the bodyhttp://www.sciencedaily.com/releases/2012/11/121115162849.htm Chemical engineers have now designed an injectable gel that responds to the body's high temperature by forming a reinforcing network that makes the gel much more durable, allowing it to function over a longer period of time.Thu, 15 Nov 2012 16:28:28 ESThttp://www.sciencedaily.com/releases/2012/11/121115162849.htmArginine and proline enriched diet may speed wound healing in diabeteshttp://www.sciencedaily.com/releases/2012/11/121115162135.htm A diet enriched with arginine and proline could speed diabetes-related wound healing, a new study suggests.Thu, 15 Nov 2012 16:21:21 ESThttp://www.sciencedaily.com/releases/2012/11/121115162135.htmNeurons made from stem cells drive brain activity after transplantation in laboratory modelhttp://www.sciencedaily.com/releases/2012/11/121115152657.htm Scientists are able to make neurons and other brain cells from stem cells, but getting these neurons to properly function when transplanted to a host has proven more difficult. Now, researchers have found a way to stimulate stem cell-derived neurons to direct cognitive function after transplantation to an existing neural network.Thu, 15 Nov 2012 15:26:26 ESThttp://www.sciencedaily.com/releases/2012/11/121115152657.htmQuick test speeds search for Alzheimer's drugs: Compound restores motor function and longevity to fruit flieshttp://www.sciencedaily.com/releases/2012/11/121115152655.htm Researchers report that an efficient, high-volume technique for testing potential drug treatments for Alzheimer's disease uncovered an organic compound that restored motor function and longevity to fruit flies with the disease.Thu, 15 Nov 2012 15:26:26 ESThttp://www.sciencedaily.com/releases/2012/11/121115152655.htmParkinson's disease protein causes disease spread and neuron death in healthy animalshttp://www.sciencedaily.com/releases/2012/11/121115152550.htm Understanding how any disease progresses is one of the first and most important steps towards finding treatments to stop it. This has been the case for such brain-degenerating conditions as Alzheimer's disease. Now, after several years of incremental study, researchers have been able to piece together important steps in how Parkinson?s disease (PD) spreads from cell to cell and leads to nerve cell death.Thu, 15 Nov 2012 15:25:25 ESThttp://www.sciencedaily.com/releases/2012/11/121115152550.htmCellphone bans associated with fewer urban accidentshttp://www.sciencedaily.com/releases/2012/11/121115141637.htm Cellphones and driving go together like knives and juggling. But when cellphone use is banned, are drivers any safer? It depends on where you're driving, a new study says. The study found that, long-term, enacting a cellphone ban was associated with a relative decrease in the accident rate in urban areas. However, in very rural areas, cellphone bans were associated with higher accident rates than would otherwise be expected.Thu, 15 Nov 2012 14:16:16 ESThttp://www.sciencedaily.com/releases/2012/11/121115141637.htmPotential new treatment to stop Alzheimer's disease: Molecular 'tweezers' break up toxic aggregations of proteins in mouse modelhttp://www.sciencedaily.com/releases/2012/11/121115141635.htm Using a specific biological compound they call molecular "tweezers," researchers report that, for the first time in a living mouse model for Alzheimer's (AD), the compound cleared the existing amyloid ? and Tau aggregates, and proved protective to the neuron's synapses, another target common to AD.Thu, 15 Nov 2012 14:16:16 ESThttp://www.sciencedaily.com/releases/2012/11/121115141635.htm
