background: tannase can be obtained from the various sources for example tannin rich plants; however microbial sources are preferred for industrial production. in microbial sources, the aspergillus and penicillium genus and lactic acid bacteria mostly produce tannase. however, it has been identified that this enzyme is produced by many fungi and bacteria, but researches are continuing to find n...

We previously demonstrated that kidney and urine levels of angiotensin-(1-7) [ANG-(1-7)] were increased in pregnancy. To explore the role of ANG-(1-7) on fluid and electrolyte homeostasis during pregnancy, we evaluated the effect of the ANG-(1-7) antagonist D-alanine-[ANG-(1-7)] (A-779) on kidney function. Virgin and pregnant rats received infusion of vehicle or A-779 (48 microg.kg(-1).h(-1)) f...

medicinal plants are a source of great economic value all over the world. nature has bestowed on us a very rich botanical wealth and large number of diverse types of plants grows in different parts of the country. in this study the in vitro antimicrobial activity of crude ethanolic, methanolic and water extracts of the stem bark of o.basilicum were investigated. the extracts exhibited antimicro...

objective: the present study was undertaken to evaluate anti-depressant activity of myristica fragrans(ms). materials and methods: male wistar rats were subjected to imipramine and herbal extract ofms for their antidepressant activity using forced swimming test (fst), reserpine reversal test (rrt), haloperidol-induced catalepsy (hic), and pentobarbitone sleeping time (pst). results: administrat...

cancer is a major cause of death worldwide and causes serious problems in human life. it is developed by uncontrolled growth of a cell or a group of cells. there are many difficulties in treatment of cancer and many researchers are involved in investigating for effective drugs to treat the disease. caryophyllaceae is a large family of about 86 genera and 2200 herbaceous or subshrub species. the...

nano dithiocarbamate (dtc) complex have been prepared by reaction between dithiocarbamate and metal salt under ultrasound irradiation. reaction conditions such as the ligand dtc and phennantroline concentration, aging time and the ultrasonic device power show important roles in the size, morphology and growth process of the final products. the dithiocarbamate complex nanoparticles have been pre...

the uses of non-steroidal anti-inflammatory drugs (nsaids) are limited by a variety of side effects. so research on preparing new analgesic agents is important. according to some reports about the analgesic activity of hydrazide and hydrazine derivatives a new series of these compounds were synthesized in order to obtain new analgesic compounds. the final compounds 10a-10e and 15a-15d were prep...

substituted schiff bases (hydrazones) 5a-j have been prepared from the starting material 2-chloro pyridine-3-carboxylic acid 1 by a sequence of reactions like reaction with 2-amino-6-nitro benzothiazole (ullamann condensation), thionyl chloride, hydrazine hydrate and different aromatic aldehydes. on cyclocondensation of 5a-j with thioglycolic acid in dry 1,4-dioxane furnished desired compounds ...

mother's mental health status during pregnancy has important effects on fetal growth and development. however, there are few studies concerning association of maternal depression and biophysical profile (bpp) of the fetus. we performed this research to know if maternal depression has any association with fetal bpp score. for measuring depression, farsi version of patient health questionnaire-9 ...
