drug resistance enables cancer cells to break away from cytotoxic effect of anticancer drugs. identification of resistant phenotype is very important because it can lead to effective treatment plan. there is an interest in developing classifying models of resistance phenotype based on the multivariate data. we have investigated a vibrational spectroscopic approach in order to characterize a sen...

The aim of this study was to determine the variations among cephalic plates of individuals in two populations of Clinopodes flavidus in Alborz Mountains, by means of landmark-based techniques of geometric morphometrics. Therefore, 17 landmarks and semi-landmarks on the coxosternite of poison claw and seven landmarks and semi-landmarks on the tarsangulum of poison claw were selected using TpsDig...

Garra rufa is one of the 73 Garra species of the family Cyprinidae. Scales are used more commonly than any other structure in population dynamic studies, because of their transparency, ease of sampling, and the minimal in-juries caused to the fish during their removal. To discriminate fish from different rivers including Bashar, Behbahan, Gerdab, Kheirabad, Kooshk-e-Bahram, Mazoo, Palangan, Sen...
