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...
In this research, high oxygen-barrier films were organized based on low-density polyethylene (LDPE)/ ethylene vinyl alcohol (EVOH)/ polyethylene-grafted maleic anhydride (LDPE-g-MA) compatibilizer. The effects of 10–30 wt. % EVOH and 0–10 wt. % LDPE-g-MA loadings on the properties of final films were evaluated. The morphology of specimens was observed by using scanning electron microscopy (SEM)...
Thermal stability and the kinetics of the grain growth of nano-crystalline Mg-6Al-1Zn-1Si alloy prepared via mechanical alloying (MA) were investigated. It started with elemental powders, using a variety of analytical techniques including differential scanning calorimetry (DSC), X-ray diffraction method (XRD), and scanning electron microscopy (SEM) coupled with energy dispersive spectrometry (E...
U-Th zircon SHRIMP and U-Th-total Pb monazite CHIME ages of 6 typical samples were established among different rock types outcropped into the Chah-Dozdan batholith from Iran. The zircon population displays simple internal structures in samples of the Chah-Dozdan batholith. The zircon crystals have well-preserved magmatic characteristics. In all population, the rims display younger ages than the...
