ôbjective: to compare the effectiveness and safety of the methylphenidate produced in ïran (stimdate®) with its original brand (ritalin®) in children with âttention deficit hyperactivity disorder (âdhd). methods: ïn this double-blinded randomized clinical trial, 30 patients with âdhd who were 6 to 16 years old, were divided into two groups: 15 in stimdate® and 15 in ritalin® group. the two grou...

an experiment was conducted on eight weak and anaemic goats revealed pale conjunctivae, increased heart rate, rough hair coat, dullness and depression. the haematology showed significantly decreased haemoglobin (7.37±0.16 g %), packed cell volume (pcv)(23.37±0.56%),total erythrocyte count (tec)(8.12±0.18 million/cumm), mean corpuscular haemoglobin (mch) (9.10±0.30 pg) and mean corpuscular volum...

water samples were collected from five selected mangrove ecosystems along kerala coast, north of cochin, on seasonal basis and analysed for various hydrographic parameters. to explain spatiotemporalvariations and the processes controlling their distribution, anova (two factor without replication),correlation and principal component analysis were carried out. concentration of total nitrogen vari...

the solvent extraction of rare earth metal ions from nitrate solutions by 5.11.17.23-tetra-tert-butyl-25,27-bis(diethylcarbamoylmethoxy)-26,28-dihydroxycalix[4]arene (l) in 1,2-dichloroethane has been investigated. the alalysis of the extraction equilibrium obtained from a mixture of la3+, eu3+, er3+ and y3+ revealed that the extracted species have a 1:1 metal/ligand ratio. the intra-group sepa...

co-precipitation procedure was applied in order to obtain different kinds of magnetic nanoadsobents for the removal of pb(ii) and cu(ii) toxic metal ions from wastewater samples. prepared nanoadsorbents were characterized by fourier transform infrared spectroscopy (ft-ir), x-ray diffractometer (xrd), scanning electron microscopy (sem) and thermogravimetric analysis (tga). the average sizes of t...

salinity is one of major stresses which can severely limit plant production, especially in the arid and semi-arid regions. the present study was carried out to evaluate the impact of salinity stress on some physio-biochemical parameters in nitre bush plants (nitraria schoberi). thus, an experiment was carried out under natural conditions and salinity stress was induced by a combination of diffe...

background: coronary artery bypass graft (cabg) surgery is very traumatic and makes patients very nervous. since it is a main task of nurses to improve patients' comfort and safety, this study investigated the effect of therapeutic touch in cardiovascular patients' anxiety before cabg surgery. methods: in a controlled clinical trail study the simple random sampling was used to select 44 patient...

the purpose of this paper was to review the commercially available periodontal dressings, their physical and chemical properties, biocompatibility and therapeutic effects. electronic search of scientific papers from 1956 to 2012 was carried out using pubmed, scopus and wiley interscience search engines using the searched terms periodontal dressing, periodontal pack. numerous in vitro and in viv...

oxime extractants 3-tert-butyl-2-hydroxy-5-methyl benzaldehyde oxime (hl1) and 3-tert-butyl-2-hydroxy-5-methoxy benzaldehyde oxime (hl2) were synthesized and characterized by conventional spectroscopic methods. suitable lipophilic nature of the prepared extractants allowed examining the ability of these molecules for extraction-separation of copper from its mixture with normally associated meta...
