the role of cu, zn and co in human physiology is well documented. isatin and glycine have inhibitory effects on central nervous system. to capitalize on these features metal complexes of isatin-3-glycine were prepared and evaluated for anticonvulsant activity. the cu (ii) complex was found to be most active among the compounds. the compounds were screened against staphylococcus aureus, escheric...
experiment was conducted to evaluate the effect of l-glutamine on coated sperm freezing by using four rams. semen was collected by artificial vagina contact with a tube containing tris-fructose-egg yolk 15%. samples were pooled and centrifuged. after removing supernatant and diluting pellet, samples were split into 5 equal part and added 0, 40, 80, 120 and 160 mm l-glutamine. samples were froze...

a comprehensive study pertaining to the emulsion liquid membrane (elm) extraction process to enrich dilute aqueous solutions of silver salt is presented. the study has highlighted the importance and influence of membrane composition for maximizing the extraction of ag+ ions. the liquid membrane was made up of cyanex-302 as an extractant and the industrial solvent mainly consists of paraffinic a...
the aim followed in this research was to determine the effect of benzyladenin and storage conditions on bulbil formation, germination percentage and growth in iranian tareh (allium ampeloprasum ssp.persicum). immature inflorecences were treated with different concentrations (0,10,50 and 100 ppm) of ba to form bulbils. the experiment was done in rcbd with three replications in esfahan center for...
an action resulting from an object like human's damaging action can cause liability for those who possess them. the french civil law at its approval time (1804) had not predicted this principle and just in articles 1385, 1386, the liability of damages resulting from two types of objects, i.e. animals and buildings due to imposing great damages by them had been predicted by french law. howe...

introduction: acute lymphoblastic leukemia (all ) is the most worldwide common type of childhood cancer. methylenetetrahydrofolate reductase (mthfr) and 5-methyltetrahydrofolate-homocysteine methyltransferase (mtr) are crucial enzymes in folate pathways. folate availability is critical factor for dna integrity, required for the transfer of methyl group in the biosynthesis of thymidilate. proced...
روش تکراری استاندارد برای حل مسائل کم ترین مربعات بزرگ و تنک min???b-ax?_2 ?, a?r^(m×n) ، روش cgls است که از نظر ریاضی معادل به کارگیری روش گرادیان مزدوج روی معادله ی نرمال a^t ax= a^t b است. ما روش های جای گزین دیگری را با استفاده از ماتریس b?r^(n×m) و به کارگیری روش کم ترین مانده ی تعمیم یافته (gmres) روی min???b-abz?_2 ? یا min???bb-bax?_2 ? بررسی می کنیم. هم چنین، برای روش های gmres، یک شرط...
objective(s):valproic acid (vpa), a drug used in the treatment of neurological disorders, has been shown to have cytotoxic effects on cancer cells through different mechanisms. telomerase, a ribonucleoprotein reverse transcriptase, is responsible for elongation of the telomere and is activated in cancers. a relation between telomerase activity and resistance to apoptosis has been established. t...
