| Posted: 10 Oct 2011 06:45 PM PDT Family history of Alzheimer disease is associated with several age-related changes that appear to influence Alzheimer disease (AD) biomarker abnormalities beyond the increased risk of the APOE4 gene, according to a new report.  |
| Posted: 10 Oct 2011 02:30 PM PDT Researchers have announced a new technique to reprogram human cells into stem cells. Their process increases the efficiency of reprogramming by 100-fold and generates cells of a higher quality at a faster rate. By adding two protein factors to the current mix of four, scientists brought about dramatic improvement in the efficiency of reprogramming and the robustness of stem cell development.  |
| Posted: 10 Oct 2011 02:30 PM PDT Biologists have discovered that under stressful conditions, such as neurodegeneration due to Alzheimer's or Parkinson's disease, synapses grow excessively, potentially contributing to dysfunction.  |
| Posted: 10 Oct 2011 02:30 PM PDT Although it is a small study and more clinical trials are needed, treatment with the medication gantenerumab appeared to result in a reduction in brain amyloid levels in patients with Alzheimer disease, according to a new report.  |
| Certain dietary supplements associated with increased risk of death in older women, study suggests Posted: 10 Oct 2011 02:30 PM PDT Consuming dietary supplements, including multivitamins, folic acid, iron and copper, among others, appears to be associated with an increased risk of death in older women, according to a new report.  |
| Can antivirulence drugs stop infections without causing resistance? Posted: 10 Oct 2011 02:30 PM PDT Antivirulence drugs disarm pathogens rather than kill them, and although they could be effective in theory, antivirulence drugs have never been tested in humans. A new study reveals these drugs have the potential to fight infection while avoiding the pitfalls of drug resistance.  |
| Sexual selection by sugar molecule helped determine human origins, researchers say Posted: 10 Oct 2011 02:30 PM PDT Researchers say that losing the ability to make a particular kind of sugar molecule boosted disease protection in early hominids, and may have directed the evolutionary emergence of our ancestors, the genus Homo.  |
| Restless legs syndrome may raise high blood pressure risk in middle-aged women Posted: 10 Oct 2011 02:30 PM PDT Middle-aged women with restless legs syndrome have an increased risk of hypertension. As symptoms of restless legs syndrome increase, the prevalence of high blood pressure increases.  |
| Cancer: Molecule found to inhibit metastasis in colon and melanoma cancers Posted: 10 Oct 2011 02:30 PM PDT Researchers have shown that a protein can inhibit metastasis of colon and melanoma cancers. CXCL12 proteins effectively blocked metastasis of the colon cancer and dramatically improved survival time, with the dimer showing effectiveness in blocking melanoma metastasis as well, a new study shows.  |
| Crossing legs after severe stroke may be a good sign of recovery Posted: 10 Oct 2011 02:30 PM PDT People who are able to cross their legs soon after having a severe stroke appear to be more likely to have a good recovery compared to people who can't cross their legs. That's according to new research.  |
| Water channels in the body help cells remain in balance Posted: 10 Oct 2011 06:29 AM PDT Water channels exist not only in nature – microscopical water channels are also present in the cells of the body, where they ensure that water can be transported through the protective surface of the cell. Scientists have discovered that one type of the body's water channels can be modified such that it becomes more stable, which may be significant in the treatment of several diseases.  |
| New strategy to accelerate blood vessel maturation has therapeutic potentials for ischemic diseases Posted: 10 Oct 2011 06:28 AM PDT Researchers have described a new mechanism to enhance the restoration of the blood flow in ischemic diseases, which are among the leading causes of death worldwide. The scientists demonstrate that blocking the protein PhD2 in white blood cells accelerates the maturation of blood vessels.  |
| Experimental vaccine protects monkeys from blinding trachoma Posted: 10 Oct 2011 06:27 AM PDT An attenuated, or weakened, strain of Chlamydia trachomatis bacteria can be used as a vaccine to prevent or reduce the severity of trachoma, the world's leading cause of infectious blindness, suggest new findings from a study in monkeys.  |
| Giant 'kraken' lair discovered: Cunning sea monster that preyed on ichthyosaurs Posted: 10 Oct 2011 04:55 AM PDT Long before whales, the oceans of Earth were roamed by a very different kind of air-breathing leviathan. Snaggle-toothed ichthyosaurs larger than school buses swam at the top of the Triassic Period ocean food chain, or so it seemed before paleontologist Mark McMenamin took a look at some of their remains in Nevada. Now he thinks there was an even larger and more cunning sea monster that preyed on ichthyosaurs: a 'kraken' of such mythological proportions it would have sent Captain Nemo running for dry land.  |
| Posted: 10 Oct 2011 04:49 AM PDT A new non-invasive technique for measuring how well the heart and blood vessels function in patients already suffering from coronary artery disease could, in a single test, identify which abnormally narrowed blood vessels are the most likely to lead to further cardiovascular complications.  |
| Baltic Sea contributes carbon dioxide to the atmosphere, study shows Posted: 10 Oct 2011 04:48 AM PDT The Baltic Sea emits more carbon dioxide than it can bind. Local variations have increased the exposure of the Bay of Bothnia. These are the results from a study of how carbon dioxide flows between the water of the Baltic Sea and the atmosphere, carried out by scientists in Sweden.  |
