| Discovery of essential genes for drug-resistant bacteria reveals new, high-value drug targets Posted: 14 Sep 2012 04:16 PM PDT Biomedical scientists collaborating on translational research are reporting the discovery of a novel, and heretofore unrecognized, set of genes essential for the growth of potentially lethal, drug-resistant bacteria. |
| Posted: 14 Sep 2012 11:00 AM PDT Biologists have outlined how the interaction of genes, proteins that bind DNA, and molecules that modify those genes and proteins, direct the development of stem cells into mature heart cells. |
| BRCA mutations may be 'Achilles’ heel' for some metastatic breast cancers Posted: 14 Sep 2012 10:53 AM PDT Recent research could reveal whether metastatic breast cancer patients with BRCA gene mutations are particularly responsive to a drug regimen that includes Veliparib, an investigational drug believed to hamper cancer cells. |
| 'Smart bomb' investigational breast cancer regimen provides promising outcome for retired minister Posted: 14 Sep 2012 10:53 AM PDT A 66-year-old Houston woman's golf ball-sized breast tumor is now almost invisible to the naked eye after only four rounds of an investigational drug regimen. |
| Healthy outlook leads to a healthy lifestyle, study suggests Posted: 14 Sep 2012 10:32 AM PDT A 'can do' attitude is the key to a healthy lifestyle, economists have determined. |
| Gingko biloba does not improve cognition in multiple sclerosis patients, study finds Posted: 14 Sep 2012 10:31 AM PDT Many people with multiple sclerosis for years have taken the natural supplement Gingko biloba, believing it helps them with cognitive problems associated with the disease. But the science now says otherwise. A new study says Gingko biloba does not improve cognitive performance in people with multiple sclerosis. |
| Posted: 14 Sep 2012 10:31 AM PDT Using ultrasound waves, engineers have found a way to enhance the permeability of skin to drugs, making transdermal drug delivery more efficient. |
| X-rays reveal the self-defence mechanisms of bacteria Posted: 14 Sep 2012 10:20 AM PDT A research group in Denmark has gained unique insight into how bacteria control the amount of toxin in their cells. The new findings can eventually lead to the development of novel forms of treatment for bacterial infections. |
| Researchers find our inner reptile hearts Posted: 14 Sep 2012 10:20 AM PDT Researchers have finally succeeded in showing that the spongy tissue in reptile hearts is the forerunner of the complex hearts of both birds and mammals. The new knowledge provides a deeper understanding of the complex conductive tissue of the human heart, which is of key importance in many heart conditions. |
| Diabetes drug could help fight Alzheimer's disease, study reveals Posted: 14 Sep 2012 10:15 AM PDT A drug designed for diabetes sufferers could have the potential to treat neurodegenerative diseases like Alzheimer's, a new study reveals. |
| How common gene mutation affects kids with autism spectrum disorders Posted: 14 Sep 2012 10:14 AM PDT In children with Autism Spectrum Disorders (ASD), a common gene mutation has been found to impact the network of connections between different areas of the brain involved in social behavior, such as recognizing the emotions shown on people's faces. |
| Posted: 14 Sep 2012 09:38 AM PDT A syndrome called "post-operative cognitive decline" has been coined to refer to the commonly reported loss of cognitive abilities, usually in older adults, in the days to weeks after surgery. In fact, some patients time the onset of their Alzheimer's disease symptoms from a surgical procedure. Exactly how the trio of anesthesia, surgery, and dementia interact is clinically inconclusive, yet of great concern to patients, their families and physicians. A new study using a mouse model of Alzheimer's disease shows that surgery itself, rather than anesthesia, has the more profound impact on a dementia-vulnerable brain. |
| Sleep researchers study value of preschool naps Posted: 14 Sep 2012 09:38 AM PDT Parents may feel it's clear that missing a nap means their young children will be grumpy and out-of-sorts, but scientists who study sleep say almost nothing is known about how daytime sleep affects children's coping skills and learning. Now researchers hope to significantly advance knowledge about how napping and sleep affect memory, behavior and emotions in preschoolers. |
| Majority of U.S. schools not ready for next pandemic, researchers say Posted: 14 Sep 2012 05:20 AM PDT A new study finds many U.S. schools are not prepared for bioterrorism attacks, outbreaks of emerging infectious diseases or pandemics. |
| Obesity more common among rural residents than urban counterparts, study finds Posted: 14 Sep 2012 05:09 AM PDT There may be two significant reasons why rural residents are more likely to be overweight: Cultural diet and physical isolation. |
| Pinball as a model for dealing with grief Posted: 14 Sep 2012 05:07 AM PDT The process of grieving can be compared to the workings of a pinball machine, where mourners' movement between different stages of grief such as shock and depression may be unpredictable, according to new research. |
| New test to crack down on athlete-cheating with drugs Posted: 14 Sep 2012 05:07 AM PDT Scientists have developed a new test to catch growth hormone drugs-cheats in sport. The test is based on the measurement of two proteins in the blood, insulin-like growth factor-I and the amino terminal pro-peptide of type III collagen. Both of these proteins, which act as markers of growth hormone use, increase in response to growth hormone. |
| Second-hand smoking affects neurodevelopment in babies Posted: 14 Sep 2012 05:06 AM PDT A new study shows that newborns that have been exposed to nicotine from both active and passive smoking mothers show poor physiological, sensory, motor and attention responses. |
| Disorder of neuronal circuits in autism is reversible, new study suggests Posted: 14 Sep 2012 05:06 AM PDT People with autism suffer from a pervasive developmental disorder of the brain that becomes evident in early childhood. Medical researchers have identified a specific dysfunction in neuronal circuits that is caused by autism. They have also reversed these neuronal changes in an animal model. These findings are an important step in drug development for the treatment for autism. |
| Huntington’s gene mutation carriers learn faster Posted: 14 Sep 2012 05:06 AM PDT People who bear the genetic mutation for Huntington's disease learn faster than healthy people. The more pronounced the mutation was, the more quickly they learned. |
| Protein linked to hunger also implicated in alcoholism Posted: 14 Sep 2012 05:06 AM PDT Researchers have found new links between a protein that controls our urge to eat and brain cells involved in the development of alcoholism. The discovery points to new possibilities for designing drugs to treat alcoholism and other addictions. |
| Low cost design makes ultrasound imaging affordable to the world Posted: 13 Sep 2012 05:39 PM PDT An underwater sonar technology expert has invented the first ultra low-cost, portable ultrasound scanner that can be plugged into any computer with a USB port and could save the lives of hundreds of thousands of women and children around the world. |
| Insulin: Charting the SH2 pool Posted: 13 Sep 2012 05:36 PM PDT New research describes a large set of interactions (interactome) which maps the range of phosphotyrosine (pTyr)-dependent interactions with SH2 domains underlying insulin (Ins), insulin-like growth factor-1 (IGF-1) and fibroblast growth factor (FGF) signaling pathways. |
| Children's intensive care units performing well despite low staffing levels Posted: 13 Sep 2012 05:36 PM PDT Standards of care in children's intensive care units come under scrutiny in a new audit report. |
| Water quality study shows need for testing at North Carolina migrant camps Posted: 13 Sep 2012 05:34 PM PDT The drinking water at one-third of migrant farmworker camps in eastern North Carolina failed to meet state quality standards, according to a new study. |
