nano silica sulfuric acid as a solid acid, was described to be an effective catalyst for one-pot three-component reaction of kojic acid, aryl aldehydes and indoles for the preparation of 2-substituted aryl (indolyl) kojic acid derivatives. the catalyst was prepared by combination of chlorosulfonic acid to nano silica gel. the size of nanoparticles were observed with sem.all prepared compounds w...

background & aim: purslane (portulaca oleracea l.), belongs to the portulacaceace family, grows in many parts of iran. results of previous studies were indicated purslane is a rich source of essential fatty acids of omega-3 and omega-6.  portulaca oleracea is a widespread weed, being the eighth common plants of the world. the aim of current study was to compare the essential fatty acids com...

fabrication and electrochemical characterization of a sensor for the determination of epinephrine (ep), uric acid (ua) and folic acid (fa) is described. the sensor  was prepared using carbon paste electrode (cpe) modified with 3,4-dihydroxybenzaldehyde-2,4-dinitrophenylhydrazone (ddp) and carbon nanotubes (cnts), which makes the modified electrode highly sensitive for the electrochemical detect...

in current research relationship between eicosapentaenoic acid (epa) and docosahexaenoic acid (dha) (% of total fatty acids) in edible tissue (muscle) of green tiger shrimp (penaeus semisulcatus) and lobster (thenus orientalis) collected from persian gulf, was investigated with some biological factors (total length, total weight and sex). results showed that in all two species, epa and dha perc...

this study was conducted to determine the effect of foliar salicylic acid (sa) and citric acid (ca) applications on growth, biochemical characteristics and essential oil content of thyme (thymus vulgaris l.) grown under field conditions. salicylic acid (0.5 and 1 mm) and citric acid (5 and 10 mm) were applied three times during the vegetation at 15 day intervals. results revealed that foliar ap...

artichoke (cynara scolymus l) belongs to asteraceae. a factorial experiment based on the randomized complete block design with three replications was carried using depths of root available water (raw) and sowing time (st) as treatments. leaf length and width, number of leaves per plant and the biomass yield were recorded before laboratory analysis. in laboratory total phenols, total flavonoids,...

objective(s):the aim of this study was to evaluate the oxidative status and dna integrity in testes of wistar rat offspring exposed to omega-9 monounsaturated (mufa) at different times of late organogenesis. materials and methods:sixty female rats were divided into six groups of 10 animals. the first group served as control and received the drug vehicle, olive oil (1 ml/kg/day). the second, thi...

background: omega-3 fatty acids have established beneficial effects for cardiovascular disease. the use of omega-3 supplements for patients with non-alcoholic fatty liver disease (nafld) was proposed. the purpose of this study was to review the relationship between omega-3 fatty acids intake and nafld. methods: in this study, the terms such as nafld, omega-3 fatty acids, docosahexanoic acid, an...

conclusions there was no difference between the effects of 2 g of epa or dha supplementation for 12 weeks on the levels of total cholesterol, ldl-c, hdl-c, tc/hdl-c, tg/hdl-c, and ldl-c/hdl-c; however, it had a desirable effect on the level of tg in a way that the effect of dha was clearer. results from 105 included patients, 97 (31 in epa, 33 in dha, and 33 in control groups) completed the stu...
