Caffeine and the analog CGS 15943 inhibit cancer cell growth by targeting the phosphoinositide 3-kinase/Akt pathway.
Cancer Biol. Ther. 15(5) , 524-32, (2014) Caffeine is a naturally occurring methylxanthine that acts as a non-selective adenosine receptor antagonist. Epidemiological studies demonstrated habitual coffee drinking to be significantly associated with liver cancer survival. We aimed to investigate the e... |

The impact of different proportions of a treated effluent on the biotransformation of selected micro-contaminants in river water microcosms.
Int. J. Environ. Res. Public Health 11(10) , 10390-405, (2014) Attenuation of micro-contaminants is a very complex field in environmental science and evidence suggests that biodegradation rates of micro-contaminants in the aqueous environment depend on the water matrix. The focus of the study presented here is the system... |
