| Plant flavonoid luteolin blocks cell signaling pathways in colon cancer cells Posted: 22 Jan 2012 05:12 PM PST Luteolin is a flavonoid commonly found in fruit and vegetables. This compound has been shown in laboratory conditions to have anti-inflammatory, anti-oxidant and anti-cancer properties but results from epidemiological studies have been less certain. New research shows that luteolin is able to inhibit the activity of cell signaling pathways (IGF and PI3K) important for the growth of cancer in colon cancer cells.  |
| Sweeping genetic analysis of rare disease yields common mechanism of hypertension Posted: 22 Jan 2012 12:25 PM PST Analyzing all the genes of dozens of people suffering from a rare form of hypertension, researchers have discovered a new mechanism that regulates the blood pressure of all humans.  |
| Vaccines to boost immunity where it counts, not just near shot site Posted: 22 Jan 2012 12:25 PM PST Researchers have created synthetic nanoparticles that target lymph nodes and greatly boost vaccine responses.  |
| Genetic mechanism linked to congenital heart disease identified Posted: 22 Jan 2012 12:25 PM PST Scientists have identified a finely tuned mechanism by which fetal heart muscle develops into a healthy and fully formed beating heart -- offering new insight into the genetic causes of congenital heart disease and opening the door to one day developing therapies to fight this chronic and potentially fatal disorder.  |
| New understanding of chronic pain Posted: 22 Jan 2012 12:24 PM PST Millions of people worldwide suffer from a type of chronic pain called neuropathic pain, which is triggered by nerve damage. Precisely how this pain persists has been a mystery, and current treatments are largely ineffective. But scientists, using a new approach known as metabolomics, have now discovered a major clue: dimethylsphingosine (DMS), a small-molecule byproduct of cellular membranes in the nervous system. In their new study, the scientists found that DMS is produced at abnormally high levels in the spinal cords of rats with neuropathic pain and appears to cause pain when injected. The findings suggest inhibiting this molecule may be a fruitful target for drug development.  |
| Anti-infective drug shortages pose threat to public health and patient care Posted: 20 Jan 2012 03:29 PM PST Shortages of key drugs used to fight infections represent a public health emergency and can put patients at risk, according to a new review. Frequent anti-infective shortages can substantially alter clinical care and may lead to worse outcomes for patients, particularly as the development of new anti-infectives has slowed and the prevalence of multidrug-resistant pathogens is increasing.  |
| How well does protective headgear works for small children participating in winter activities? Posted: 20 Jan 2012 03:27 PM PST Researchers find surprising results regarding how much protection helmets afford children participating in winter sports activities.  |
| Tactile imaging sensor can assist doctors with early identification of tumors Posted: 20 Jan 2012 03:24 PM PST A handheld tactile imaging sensor could aid doctors in early identification of cancerous lesions or tumors.  |
| Abnormal chromosome indicates outcome for rare brain tumor Posted: 19 Jan 2012 09:35 PM PST A new trial shows that, in adults with an oligodendroglioma brain tumor, a chromosomal abnormality is associated with a near-doubling of median survival time and better prognosis when combined chemotherapy and radiation therapy is compared to radiation therapy alone.  |
| Accelerated infant growth increases future asthma symptom risk Posted: 19 Jan 2012 09:30 PM PST Accelerated growth in the first three months of life, but not fetal growth, is associated with an increased risk of asthma symptoms in young children, according to a new study.  |
