Increase in counterfeit antimalarial drugs prompts call for crackdown, better detection
...f artesunate in tablets may mean that the Fast Red dye test, widely used for screening the quality of artesunate tablets, yields false-positive results, depending on how much artesunate is present in the fakes. Also, many fake artesunate tablets contain other drugs, possibly because the counterfeiters ar...Targeted lymph node examination improves staging of colon cancer

...for tooth tissue engineering applications. Hoechst dye profiling and immuno-sorting methods were used to generate enriched clonal dental stem cell (DSC) lines. Expanded DSC and non-DSC lines are currently being examined, by both in vitro and in vivo methods, to define their potential to differentiate.

...polymers and fibers. The thin coating is a type of dye that can be applied to the surface of all types of fabrics and materials. When exposed to light, the coating acts as a photo catalyst, sparking a chemical reaction with air and killing most viral and bacterial microbes.

This study found that of the 84 patients studied, Vizilite improved either the brightness or sharpness of the identified l...MR angiography highly accurate in detecting blocked arteries
.... "MR angiography, using a small quantity of MRI dye injected into a vein in the arm, can produce detailed images of the arteries supplying the brain and can detect even minor degrees of narrowing or blockage. It does not involve exposure to x-rays and is widely regarded as a very safe, painless test,"...Probe to detect spread of breast cancer co-developed by UH scientist

At this point were just speculating on avenues of research that could be pursued. Cutter said the largest increase in the ratio has been for those whose MS started at younger ages. ...Fingerprint instead of blood sample
