Salvia is a genetically diverse genus in the Lamiaceae family, with hundreds of species distributed globally. With base chromosome numbers ranging from 6 to 19 and ploidy levels diploid octoploid, has been proposed be subdivided based on molecular data rather than morphology. However, little known about total DNA content across genus. The 141 genotypes were analyzed using flow cytometry. Sample...

In this study, freshwater fish Cyprinus carpio was exposed to sub lethal concentration of synthetic pyrethroids insecticide cypermethrin to evaluate the impact on nucleic acids in different organs. Fishes were exposed to sub lethal concentration (1/10th of LC50 value) of cypermethrin for three different durations, 7, 14 and 21 days. In seven day exposed fishes, DN...

Background & Aims: Gastric cancer is the second common cancer in Iran and it has unfortunately no diagnostic signs in early stages. Considering the role of genetic and environmental factors in the development of gastric cancer, this study aimed at evaluating DNA-content of stomach cells in patients with gastric cancer in order to find a reliable index for prediction of disease prognosis and pro...
