The study compares conventional triple screen testing with three tests performed in the first trimester. Study on new breast cancer immunoassay. The study involved measuring the radioassay and the new monoclonal antibody to quantify TK1 activity and protein levels, respectively. The same was done on 218 serum samples of postoperative breast cancer patients. Researchers concluded that the test accurately measured TK1 levels in both breast cancer cells and serum.
Researchers mistakenly create killer virus.
In a chilling development, Australian gene engineers mistakenly created a virus that quickly kills mice by destroying the animals immune systems. It s a discovery that could be used as a blueprint for creating very deadly weapons of biological warfare, according to a report in NewsEdge. The scientists were trying to create a contraceptive vaccine for mice as a pest control. Once inserted into the mice, the mousepox virus, which is a close cousin to smallpox, attacked and destroyed the immune systems. E. coli gene mapped.
