of coping mechanism in the beginning of the disorder may, over time, lose their comforting aspects while their harmful ones continue to be amplified. This, in turn, may cause the intensity of the depression to increase, making the occurrence of major...
Lab study: Protein delivered via genetically engineered virus slowed glioblasoma multiforme growth
...al drug, gancyclovir. In laboratory studies, this type
of gene therapy has proved almost 100 percent effective. But in clinical trials, it has had limited effectiveness, suggesting that the virus is not able to deliver the suicide gene effectively into a large tumor mass. "Importantly, results from t...

of cell takes away valuable space from other cells, resulting in an immune system that is less diverse and thus less capable in effectively locating and eliminating pathogens. To conduct the research, scientists at the VGTI studied mice, which h...
