Wearing sunscreen at all times when exposed could starve the body of vitamins which protect against various diseases, claim Edinburgh based scientists. The news is reported in the latest edition of the Royal Society of Chemistry journal Photochemical & Photobiological Sciences.Depletion of the ozone layer over the past four decades has resulted in increased le...Tuesday, 13-Feb-2007 / [ Details... ]
Those planning to break New Year's dieting resolutions with a feast of chocolate on Valentine's Day, should think again, according to researchers at the University of Hertfordshire.New research led by Professor Ben Fletcher and Dr Karen Pine at the University's School of Psychology, has revealed that dieting leads women into a vicious cycle of negative emotions which in turn provokes cravings for the very foods they are trying to avoid, chocolat...Tuesday, 13-Feb-2007 / [ Details... ]
In most cases, heart failure is due to the impaired ability of the heart muscle to pump blood through the body. However, in some cases, the heart no longer functions normally because it is not filled properly. This process is largely determined by the elastic scaffold protein titin. Dr. Michael Gotthardt and his co-workers at the Max Delbr?nter for Molecular Medicine (MDC) Berlin-Buch, Germany, together with Professor Hendrikus Granzier from W...Monday, 12-Feb-2007 / [ Details... ]
We all know that iron deficiencies are dangerous, but also too much iron is bad for our health. Our body stores excess iron in various tissues, where it can lead to organ failure and even death if not treated before irreversible damage has occurred. Researchers from the Innsbruck Medical University, the University of Heidelberg, Germany, and the European Molecular Biology Laboratory (EMBL) now made a surprising discovery that may lead to new therape...Monday, 12-Feb-2007 / [ Details... ]
Researchers often use animals to help them resolve problems that can be applied to people. Dr. Jean Boal, a biology professor at Millersville University of Pennsylvania, is developing a new and unique way to research the causes and effects of depression with the help of octopuses. Boal, along with Dr. Anne-Sophie Darmaillacq, a visiting postdoctoral fellow from Universite de Caen in France, is performing behavioral experiments with octopuse...Monday, 12-Feb-2007 / [ Details... ]
Efforts to create nanoparticles that deliver anticancer drugs or imaging agents to tumors while avoiding healthy cells are often stymied by a lack of known tumor targets, that is, molecules found on the surface of malignant cells but not healthy cells. While researchers continue to search for such tumor-specific markers, an international team of investigators has found a way of creating peptide-based targeting agents that do not require knowing in advance what the target is. This technique could...Monday, 12-Feb-2007 / [ Details... ]
Gold nanoparticles have shown significant promise as agents to detect and treat cancer, but researchers have had difficulty creating gold nanoparticles that have suitable pharmacological properties for use in humans. A team led by Kattesh Katti, Ph.D., principal investigator of the ...Monday, 12-Feb-2007 / [ Details... ]
During the past several years, breakthroughs in genomic and proteomic technologies have enabled researchers to more clearly identify the biochemical networks that malfunction when a healthy cell becomes malignant. Now, James Health, Ph.D., and colleagues at the California Institute of Technology have developed a new approach to ...Monday, 12-Feb-2007 / [ Details... ]
GenoMed has announced that it has found the "African gene," responsible for the much higher incidence of diabetes, high blood pressure, and kidney failure among people of African ancestry than whites. High blood pressure, and many other diseases, are roughly twice as common among African Americans than whites. For people with high blood pressure, kidney failure is five times more common among African Americans than whites. So blacks have 10 tim...Monday, 12-Feb-2007 / [ Details... ]
Siestas could be the latest way of avoiding stress and protecting the heart from disease.According to researchers at Harvard and the University of Athens Medical School, regular naps are good for the heart.After conducting a six-year study of nearly 24,000 Greek adults, the researchers found that those who took midday naps on a regular basis, lowered their risk of dying from heart...Monday, 12-Feb-2007 / [ Details... ]
