Research Could Lead To Development Of New And Effective Drugs To Treat Cancer
Date: Aug-23-2012Transcription is a cellular process by which genetic information from DNA is copied to messenger RNA for protein production. But anticancer drugs and environmental chemicals can sometimes interrupt this flow of genetic information by causing modifications in DNA. Chemists at the University of California, Riverside have now developed a test in the lab to examine how such DNA modifications lead to aberrant transcription and ultimately a disruption in protein synthesis...
Mapping Brain Activity In Patients With Brain Lesions
Date: Aug-23-2012The frontal lobes are the largest part of the human brain, and thought to be the part that expanded most during human evolution. Damage to the frontal lobes - which are located just behind and above the eyes - can result in profound impairments in higher-level reasoning and decision making. To find out more about what different parts of the frontal lobes do, neuroscientists at the California Institute of Technology (Caltech) recently teamed up with researchers at the world's largest registry of brain-lesion patients...
Why Our Perception Of Time Varies
Date: Aug-23-2012Though the seconds may tick by on the clock at a regular pace, our experience of the 'fourth dimension' is anything but uniform. When we're waiting in line or sitting in a boring meeting, time seems to slow down to a trickle. And when we get caught up in something completely engrossing - a gripping thriller, for example - we may lose sense of time altogether. But what about the idea that time flies when we're having fun? New research from psychological science suggests that the familiar adage may really be true, with a caveat: time flies when we're have goal-motivated fun...
Patients With Early-Stage Follicular Lymphoma Have Many Options, Good Outcomes
Date: Aug-23-2012A University of Rochester Medical Center study challenges treatment guidelines for early stage follicular lymphoma, concluding that six different therapies can bring a remission, particularly if the patient is carefully examined and staged at diagnosis. The research underlines the fact that when cancer strikes, modern patients and their oncologists across the United States are taking many diverse treatment paths when there is scant data to support one method over another...
Limiting The Virulence Of A. baumanni
Date: Aug-23-2012Acinetobacter baumanni, a pathogenic bacterium that is a poster child of deadly hospital acquired infections, is one tough customer. It resists most antibiotics, is seemingly immune to disinfectants, and can survive desiccation with ease. Indeed, the prevalence with which it infects soldiers wounded in Iraq earned it the nickname "Iraqibacter." In the United States, it is the bane of hospitals, opportunistically infecting patients through open wounds, catheters and breathing tubes. Some estimates suggest it kills tens of thousands of people annually...
Practicing Music For Only A Few Years In Childhood Helps Improve The Adult Brain
Date: Aug-23-2012A little music training in childhood goes a long way in improving how the brain functions in adulthood when it comes to listening and the complex processing of sound, according to a new Northwestern University study. The impact of music on the brain has been a hot topic in science in the past decade. Now Northwestern researchers for the first time have directly examined what happens after children stop playing a musical instrument after only a few years -- a common childhood experience...
Blood Processing Transformed By New Technology
Date: Aug-23-2012A pioneering surgical blood salvage technology developed at the University of Strathclyde, Glasgow, is set to transform the way major surgery is carried out by reducing blood loss in patients. HemoSep is set to revolutionise the health care sector after gaining the CE mark and receiving Canadian national approval, following highly successful clinical trials in the world leading University of Kirikkale University Hospital in Ankara, Turkey...
More Healthful Foods To Nourish The Non-Human You?
Date: Aug-23-2012The focus of nutrition for good health is quietly shifting to include consumption of food ingredients specifically designed to nourish the non-human cells that comprise 80 percent of the cells in the typical person, an authority on the topic said. Speaking at the 244th National Meeting & Exposition of the American Chemical Society, the world's largest scientific society, Robert Rastall, Ph.D., cited several factors driving these so-called "prebiotic" ingredients toward more foods...
Childhood Obesity Targeted By New Team Of Hamilton Scientists
Date: Aug-23-2012A team of McMaster University researchers and McMaster Children's Hospital clinicians have banded together to address the epidemic of childhood obesity. There's no doubt there's an issue: In Canada the number of children with obesity has tripled in the past 25 years, and now more than one in four is overweight. Of those seen for weight management at McMaster Children's Hospital in Hamilton, 80% are at risk of heart disease and one in five has pre-diabetes. Science hasn't found a cure, yet...
In Spinal Muscular Atrophy, Low Oxygen Levels May Decrease Life-Saving Protein
Date: Aug-23-2012Investigators at Nationwide Children's Hospital may have discovered a biological explanation for why low levels of oxygen advance spinal muscular atrophy (SMA) symptoms and why breathing treatments help SMA patients live longer. The findings appear in Human Molecular Genetics.* SMA is a progressive neurodegenerative disease that causes muscle damage and weakness leading to death. Respiratory support is one of the most common treatment options for severe SMA patients since respiratory deficiencies increase as the disease progresses...
