The method of choice used for preparing tissue samples can lead to biased results in the analysis of cancer patient survival. For microscopical analysis, full tissue samples provide a better picture of the immune cell activity in the tumor compared to tissue-sparing punch biopsies. A team led by the visceral surgeon Elisabeth S. Gruber and […]
As health agencies battle to stop the spread of the deadly Ebola virus in eastern DR Congo, some survivors of the disease are playing a crucial role in aiding victims of the worst outbreak in the country’s history.
