the aim of this study was to evaluate the effect of handedness and two practice types (explicit vs. implicit) on motor sequence learning. 60 girls (age range of 14 – 17 years old) were randomly assigned to four groups according to their handedness: right–handed-explicit, right–handed–implicit, left–handed-explicit, and left–handed-implicit. participants’ task was accuracy and time of sequential...

a series of complexes of the type trans-[co(acacen)(amine)2]clo4, where (acacen) is the (bis(acetyleacetone) ethylenediimine) and the amines are benzyl amine (bzlan) 1, 2-amino pyrimidine (2ampy) 2, n-methylpipirazine (nmpip) 3, 3-methyl pyridine (3mpy) 4, p-toluidine (p-toldn) 5, has been synthesized and characterized by uv-vis. and ft-ir. the kinetics of the substitution reaction of [co(acace...

introduction & objective: the brain choroids plexus (bcp) plays an important role in the cerebrospinal fluid (csf) production, but its characterization is still incomplete. collagen type iv, is one of the most important proteins of basement membrane (bm) and extracellular matrix (ecm) of bcp. in the present study we investigated the differential period of type iv collagen in basement membrane o...

Background: Cutaneous drug reaction is a common side effect of antiepileptic drugs (AEDs). In recent years, a significant increase in cases of cutaneous drug reaction due to AEDs and some changes in its pattern in our department have been noticed. Therefore, we carried out this study to present clinical and paraclinical characteristics of these cases. Methods: All records of patients who were h...

3,4-dihydropyrimidin-2(1h)-thiones were synthesized in the presence of ag nanoparticle/melamine sulfonic acid (msa) supported on silica gel. the reaction was carried out at 110 oc for 20 min under solvent free conditions. in all cases, the three component reaction proceeded smoothly to give the corresponding 3,4-dihydropyrimidin-2(1h)-thiones in moderate to good yield. we have found the best co...

Synthesizing chemical molecules is a necessary and often time-consuming process in fields like drug discovery and materials science. Here, we use recurrent neural networks to automate two tasks in chemical synthesis: 1) classifying the type of reaction two molecules will participate in, and 2) generating the correct products given the reactants and reaction type. We achieve 96% accuracy and 99%...

background: the protozoan parasite toxoplasma gondii can infect any warm blooded nucleated cells. one of the ways for human infection is ingestion of oocysts directly from soil or via infected fruits or vegetables. to survey the potential role of t. gondii oocyst in soil samples, the present study was conducted in tehran city, iran. methods: a total of 150 soil samples were collected around rub...

to August, 2009. Type 1 reaction was recorded in 32 patients among 127 (BT, BB, BL and pure neuritic) cases (25.19%). Type 2 reaction was recorded in 10 patients among 67 (BL and LL) cases (14.92%). Recurrent type 1 reaction was recorded in 20 patients and late reaction in 8 patients. All 10 patients had recurrent episodes of ENL, 6 beyond 2 years of completion of MDT. Most of these patients we...
