There are many environmental compounds and biologically-active synthetic compounds, such as toxins and drugs, whose molecular mechanisms in a living cell still need to be investigated. Therefore, one approach is to computationally analyze the biological activity of compounds in a systematic manner. Thus we have been developing chemical bioinformatics methods to evaluate the reactivity of bioche...

A biological study was conducted to find out about reproduction and feeding of G. lacustris in Neur Lake from northwest mountains of Iran. Plankton diversity, hydro-chemical factors and substrate characteristic were recorded monthly. Findings showed that reproduction period of this species was short and limited to May and the mean brood size was 10.2 ± 5.3 eggs per female. The hydro-chemical an...
