Elimination of Cd2+ and Mn2+ from Wastewaters Using Natural Clinoptilolite and Synthetic Zeolite P

This study deals with the uptake of Cd2+ and  Mn2+ ions from contaminated water using two Iranian natural clinoptilolite-rich tuffs from Meyaneh (Z-m), and Semnan (Z-s) regions , and a synthetic zeolite-P from Z-m sample (Z-P) under static (batch operation) and dynamic (column operation) conditions. To investigate the selectivity of the zeolites towar...

The study of synthetic and natural pigments on the colour of the Albino Oscar

In this study, we have investigated the effects of mix of Tomato (Solanum lycopersicum) & Carrot) Daucus carota ( and red Bell pepper )Capsicum annuum( as a natural pigment source and astaxanthin as synthetic pigment sources on the skin colour of cichlid fish (Astronotus ocellatus sp., Agassiz, 1831), which are generally white with red patches in the dorsal skin. The fish were fed diets contain...

A Comparative Study upon the Therapeutic Indices of Some Natural and Synthetic Anti-inflammatory Agents

Objective(s) The aim of the present study was to compare the therapeutic indices of several agents used in treatment of inflammatory conditions which included: Vitamin E, hydro-alcoholic extracts of Glycyrrhiza glabra, Matricaria aurea, dexamethasone, piroxicam and diclofenac using Wehi-164 fibrosarcoma cells. Materials and Methods Cytotoxicity evaluation was based on vital dye exclusion ass...

Natural Products and Synthetic Biology

While the phrasing of this tripartite classification was not intended to describe the current state of natural products research, it could have been, as it provides an apt description of the field today. The organic molecules lumped under the term natural products elude an easy definition. They are a structurally diverse collection of molecules produced by organisms in an idiosyncratic fashion,...
