The complexation reactions between diacetyl monooxime (Damo), imidazole (Him), histamine (Hist) and histidine (His) with Co2+, Ni2+ and Cu2+ were studied potentiometrically in aqueous solution at 25 °C and m= 0.5 M KNO3. The overall stability constants log b's of species were obtained by computer refinement of p...
هدف از انجام این پروژه تهیه آلیاژ ) abs/pc آکریلونیتریل –بوتادی ان – استایرن/ پلی کربنات) با پایداری حرارتی بالا است، که به این منظور از سازگارکنندها و افزودنی های مناسب استفاده شده است. برای تهیه آلیاژ ها از یک اکسترودر دو پیچه ناهمسوگرد استفاده شده است. سازگارکننده های مالئیک انیدرید پیوند شده به آکریلونیتریل بوتادی ان استایرن (abs-g-ma) ، مالئیک انیدرید پیوند شده به استایرن - آکریلو نیتریل (...
A label-free electrochemical nucleic acid aptasensor for the detection of methamphetamine (MA) by the immobilization of thiolated self-assembled DNA sequences on a gold nanoparticles-chitosan modified electrode is constructed. When MA was complexed specifically to the aptamer, the configuration of the nucleic acid aptamer switched to a locked structure and the interface of the biosensor changed...
Background and Objectives: Organophosphate pesticides are used most commonly for domestic, commercial, and agricultural purposes and have been found to be highly toxic. In essence, bioremediation has become one of the most important tools for removing these compounds in the environment, considering its higher efficiency when compared with the physicochemical methods. Materials and Methods: T...
Introduction: Methamphetamine (MA) as an addictive psychostimulant drug affects the central nervous system. The present research aimed at evaluating the impact of Berberine-hydrochloride on cognitive function Improvement and neuroprotective effects in MA Addicted Rats. Methods: In this study, 27 Male Wistar rats were randomly assigned to three groups, including Control, MA addiction and MA add...
Objectives: This study aimed to compare the ratio of suicide attempts between female opium and Methamphetamine (MA) users to determine the relationship between the increased prevalence of MA and suicide risk. Methods: In this cross-sectional study, 136 drug dependent females were randomly selected from Tehran. Data gathering was performed by a demographic questionnaire and Beck Scale for Suic...
Outcome-dependent sampling (ODS) has been widely used in biomedical studies because it is a cost-effective way to improve study efficiency. However, in the setting of a continuous outcome, the representation of the exposure variable has been limited to the framework of linear models, due to the challenge in terms of both theory and computation. Partial linear models (PLM) are a powerful inferen...
