Background: We have come across the plant secondary metabolites having pesticidal properties being used in the form of pesticides. In this study, we used one of newly available and plant metabolite used as pesticide in wide agricultural fields – Karanjin, obtained from seeds of plant Pongamia pinnata. Methods: The study was conducted during the month of March 2016 at the Department of Zo...

The inhibitory effects of hinokitiol (beta-thujaplicin) on Chlamydia trachomatis D/UW-3/Cx were shown by MIC, minimum lethal concentration (MLC), and preinoculation minimal microbicidal concentration assays using HeLa 229 cells. The MIC and the MLC were both 32 microg/ml. Further evaluation of hinokitiol as a topical agent against C. trachomatis is warranted.

The bioavailability of methylmercury (MeHg) in the brains of  orange spotted groupers, captured from four creeks of Mahshahr embayment was measured.  Then the effects of this pollutant on the regulation of gene expression, acetylcholinesterase transcript levels was chosen in order to monitor the amounts of methylmercury concentrations in the creeks, and the fluctuations of mRNA expressions in t...

To investigate the effect of NaCl concentration on the survival of Aedes aegypti larvae, samples of Aedes aegypti larvae were collected from some discarded container, artificial pool from the urban area of Wahga town and exposed to 10%, 15% and 20% of NaCl concentration. The results of this study suggest that NaCl higher concentration can be used in a more human non-lethal chemical approach and...

Aculeacin A was lethal for proliferating cultures of C. albicans. However, there was a paradoxical relationship between the drug concentration and the fungicidal activity; the lethal effect was greatest at levels of 0.08 to 1.25 microgram/ml and increases in the drug concentration above this range reduced its lethal effect. A similar anomalous dose-response patterns were also observed for the i...
