objective(s): 3, 4-methylenedioxymethamphetamine (mdma) one of the methamphetamine derivatives that affect the reproductive system, has not been well understood. many young people are consumers of drugs such as mdma that can affect their reproductive capability. apoptosis is the main mechanism for male infertility. pentoxifylline (ptx) increases camp intracellularly and reduces tumor necrosis f...

the synthesis of a novel class of 2-oxoindolin-3-ylidene-(1-arylhydrazinyl)-2-aryl(alkyl)ethylidene derivativesvia a copper-catalyzed tandem reaction of isatin, arylhydrazines, sulfonyl azides and terminal alkynes is described.

drought tolerances of 55 indigenous strains of pseudomonas fluorescens were evaluated. to assess the tolerance rate of the strains to various levels of water deficit, their growth rate in nb medium containing concentrations of 40.587, 438.838 and 548.838 g of polyethylene glycol 6000 per liter of medium were utilized. water potentials of aforesaid levels were estimated as 0, - 10, - 20 and -30 ...

effects of different amounts of morning liming on blood ionic parameters and blood biochemical parameters of cultured carp ponds in dikjeh area of gonbad were investigated. 9 ponds (3 hectars) were chosen and divided in 3 treatments (1- liming 750 mg/l, 2- liming 1250 mg/l, 3- liming 1750 mg/l). liming had significant effect on blood hematocrite (p0.05) were observed between other blood paramet...

to design the equipment and facilities for preservation, storage and processing of pomegranate, it is necessary to know the specific heat and thermal conductivity of the fruit components. the specific heat of exocarp, mesocarp and of seeds of pomegranate were assessed at three moisture content levels (30, 50 and 76% for seed and mesocarp; 15, 35 and 52% for exocarp) and at four temperature leve...

extended abstract   introduction the most important indicator of climate in a region is vegetation community. climate can be different over large areas, because of changes in vegetation community. vegetation influences weather and climate in its surrounding areas mostly by way of evapotranspiration and albedo so they play a role in the earth’s energy balance. these effects on the earth’s energy...

the purpose of this study was to examine the effectiveness of nanosilver colloid as a new antimicrobial agent against erwinia in tissue culture of sugar beet for the recovery of the contaminated doubled haploid plantlets. the nanosilver colloidal solution of 4000 ppm was diluted in different concentrations (0, 50, 75, 100 and 125 ppm) and was added to the solid ms medium. in a factorial experim...

improving the processing and the recycled paper properties is one of permanent concern of papermaking. in this research, the effect of nanochitosan addition on the process and product quality made of writing and printing recycled fiber was investigated. being nano size and so its capability in access to the space between pulp suspension components and also its probable ability to make electrost...

introduction compartmental analysis allows the mathematical separation of tissues and organs to determine activity concentration in each point of interest. biodistribution studies on humans are costly and complicated, whereas such assessments can be easily performed on rodents. in this study, we aimed to develop a pharmacokinetic model of 153sm-maltolate complex as a novel therapeutic agent and...

purpose– analysis of non-prismatic beams has been focused of attention due to wide use in complex structures such as aircraft, turbine blades and space vehicles. apart from aesthetic aspect, optimization of strength and weight is achieved in use of this type of structures. the purpose of this paper is to present new shape functions, namely 3-node basic displacement functions (bdfs) for derivati...
