al-mcm-41 nanoreactors is found to be a remarkable efficient catalyst for one-pot multicomponent cyclocondensation of benzil, aniline or ammonium acetate and aromatic aldehydes for the synthesis of polysubstituted imidazoles under solvent-free conditions. the reaction was efficiently promoted by 10 mg nano-al-mcm-41 and the heterogeneous catalyst was recycled for four runs in this reaction with...

helicobacter pylori is related to iron deficiency anemia (ida) and inflammatory responses causing gastric and duodenal ulcer and carcinoma. moreover, it leads to deficiency of factors associated with iron adsorption and transfer. in the present study, we recruited 100 children (50 infected with h. pylori and 50 controls) aged 3-14 years old (40% male and 60% female) to evaluate the effect of h....

normal 0 false false false en-us x-none ar-sa background: the h-reflex is a useful electrophysiological procedure for evaluating the status of the peripheral nervous system, especially at the proximal segment of the peripheral nerve. the purpose of this study is to investigate the relation between triceps surae h-reflex and m- response latencies and thigh length in normal population, in order t...

the present experiment was conducted to determine metabolizable energy of pomegranate peel and pulp by adult cockerels. the pomegranate peel and pulp samples were gathered from three industries. this study had two experiments. each experiment was done in a completely randomized design with 4 treatments and 4 replicate (1 cockerel each). the cockerels fed conventional addition method (cam). the ...

background: corn silk (cs) is widely used in iranian traditional medicine. the aim of this study was to investigate hepatoprotective activity of cs by isolated rat liver perfusion system (irlp). methods: hydro-alcoholic extract of corn silk (10, 20, 40, and 100 mg kg-1) was evaluated for its hepatoprotective activity by irlp. phenol and flavonoid contents of the extract were determined as galli...

normal 0 false false false en-us x-none ar-sa epilepsy is more common in patients with multiple sclerosis (ms) than in the general population, occurring in 2%–3% of patients. convulsions may be either tonic–clonic in nature or partial complex. in these individuals, seizures most likely result from lesions present in the cerebral cortex and subcortical white matter. a jacksonian seizure is a typ...

let $r$ be a commutative ring with identity‎. ‎a proper ideal $p$ of $r$ is a $(n-1,n)$-$phi_m$-prime ($(n-1,n)$-weakly prime) ideal if $a_1,ldots,a_nin r$‎, ‎$a_1cdots a_nin pbackslash p^m$ ($a_1cdots a_nin pbackslash {0}$) implies $a_1cdots a_{i-1}a_{i+1}cdots a_nin p$‎, ‎for some $iin{1,ldots,n}$; ($m,ngeq 2$)‎. ‎in this paper several results concerning $(n-1,n)$-$phi_m$-prime and $(n-1,n)$-...

background and purpose: different methods such as surgery, chemotherapy, radiotherapy, hormone therapy and immunotherapy are used for treatment of melanoma cancer. unfortunately they don't always have desirable results and they may have unfavorable side effects. researchers try to find new, more effective drugs with low side effects. in this study we evaluated the cytotoxic effect of aca-1...
