Human neural stem cells study offers new hope for children with fatal brain diseases Posted: 10 Oct 2012 11:14 AM PDT Physician-scientists have demonstrated for the first time that banked human neural stem cells can survive and make functional myelin in mice with severe symptoms of myelin loss. Myelin is the critical fatty insulation, or sheath, surrounding new nerve fibers and is essential for normal brain function.

Melanoma: The wolf in sheep’s clothing Posted: 10 Oct 2012 11:11 AM PDT Melanoma is so dangerous because it tends to metastasize early on. New treatment approaches utilize, among other things, the ability of the immune defense to search out and destroy malignant cells. Yet this strategy is often only temporarily effective. A research team has discovered why this is the case: In the inflammatory reaction caused by the treatment, the tumor cells temporarily alter their external characteristics and thus become invisible to defense cells. This knowledge forms an important foundation for the improvement of combination therapies.

Squeezing ovarian cancer cells to predict metastatic potential: Cell stiffness as possible biomarker Posted: 10 Oct 2012 10:15 AM PDT New research shows that cell stiffness could be a valuable clue for doctors as they search for and treat cancerous cells before they're able to spread. The findings found that highly metastatic ovarian cancer cells are several times softer than less metastatic ovarian cancer cells.

By making animal studies easier to replicate and interpret, the workshop recommendations are expected to help funnel promising therapies to patients.

Detailed view of brain protein structure; Results may help improve drugs for neurological disorders Posted: 10 Oct 2012 10:14 AM PDT Researchers have published the first highly detailed description of how neurotensin, a neuropeptide hormone which modulates nerve cell activity in the brain, interacts with its receptor. Their results suggest that neuropeptide hormones use a novel binding mechanism to activate a class of receptors called G-protein coupled receptors.

Zinc fingers: A new tool in the fight against Huntington's disease Posted: 10 Oct 2012 10:13 AM PDT Huntington's disease (HD) is an inherited genetic disorder caused by the multiple repetition of a DNA sequence (the nucleotides CAG) in the gene encoding a protein called "Huntingtin". People who do not suffer from the disease have this sequence repeated 10 to 29 times. But in an affected person, the triplet is present more than 35 times. New research provides positive results reducing the chromosomal expression of the mutant gene, which would prevent the development of disease.

Living near livestock may increase risk of acquiring MRSA Posted: 10 Oct 2012 10:13 AM PDT New study finds regional density of livestock is an important risk factor for nasal carriage of livestock-associated MRSA for persons with and without direct contact with livestock.

3-D model for lung cancer mimics the real thing Posted: 10 Oct 2012 10:13 AM PDT A new technique that allows scientists to grow lung cancer cells in three dimensions could accelerate discoveries for a type of cancer that has benefited little from scientific research over the last several decades. The model uses biological matter to form miniature lungs.

Older age marker may be more appropriate in predicting papillary thyroid cancer prognosis Posted: 10 Oct 2012 08:22 AM PDT Researchers have shown that age 45 is no longer a useful predictor of negative outcomes in the staging of papillary thyroid cancer patients.

Eyes don't necessarily give away sleepiness in people with disabilities, study suggests Posted: 10 Oct 2012 07:21 AM PDT Visual examination of the pupils of the eyes is a standard test for alertness but to use pupil response in assessing sleepiness or exhaustion in people with physical disabilities requires a more sophisticated system, according to new research.

Does immune dysfunction contribute to schizophrenia? Genetic findings from new study Posted: 10 Oct 2012 07:20 AM PDT A new study reinforces the finding that a region of the genome involved in immune system function, called the major histocompatibility complex (MHC), is involved in the genetic susceptibility to schizophrenia.

Loss of protective heart failure protein linked to critical limb ischemia Posted: 10 Oct 2012 07:19 AM PDT Restoring diminished levels of a protein shown to prevent and reverse heart failure damage could also have therapeutic applications for patients with critical limb ischemia (CLI), suggests a new preclinical study.

Satiation hormone could increase risk of diabetes, heart attack and breast cancer in women Posted: 10 Oct 2012 06:28 AM PDT One of the body's satiation hormones, neurotensin, could raise women's risk of suffering one of three common and serious conditions: diabetes, cardiovascular disease and breast cancer. There is also a connection between the hormone and premature death in women, especially from cardiovascular disease.

New insight into cognitive changes in multiple sclerosis Posted: 10 Oct 2012 05:45 AM PDT Researchers in Ireland have recently reported new insights into cognitive changes in multiple sclerosis, using newly developed signal processing methods.

Diabetic foot ulcers linked with higher risk of death, heart attack and stroke Posted: 10 Oct 2012 05:42 AM PDT People with diabetes who develop foot ulcers are at more risk of dying prematurely than those without the complication, finds a new large-scale study. The researchers say the findings highlight the potential need for improved detection and management of those with diabetes and foot ulcers.

HPV vaccination does not lead to an increase in sex, study suggests Posted: 10 Oct 2012 05:42 AM PDT Contrary to recent discussions, the HPV vaccination does not increase sexual activity in adolescent girls, new research shows. There have been claims recently that the HPV (Human papillomavirus) vaccination increases sexual activity in adolescent girls as it effectively gives them a 'green light' to have sex because of a perceived protection against sexually transmitted infections.

Astrocytes as a novel target in Alzheimer’s disease Posted: 10 Oct 2012 05:41 AM PDT Alzheimer's disease is a severe neurodegenerative disease that affects 45% of people over 85 years of age. Medical researchers have now identified astrocytes as a novel target for the development of future treatment strategies.

Nobel Prize in Chemistry 2012: Smart receptors on cell surfaces Posted: 10 Oct 2012 05:19 AM PDT Your body is a fine-tuned system of interactions between billions of cells. Each cell has tiny receptors that enable it to sense its environment, so it can adapt to new situtations. Robert Lefkowitz and Brian Kobilka have been awarded the 2012 Nobel Prize in Chemistry for groundbreaking discoveries that reveal the inner workings of an important family of such receptors: G-protein-coupled receptors.

Is delaying premature delivery safe? Posted: 09 Oct 2012 04:26 PM PDT In a new editorial, a UK expert argues that although premature children tend to have lower cognitive ability than their peers and 14.9 million are born prematurely each year worldwide, is it really possible to stop spontaneous preterm labour?
