ucb-1 (pistacia atlantica × p. integrima) is a commercial rootstock for pistachio in some pistachio plantations across the world. this rootstock is very new in iran and recently, it has been used commercially in some plantations due to its high growth. propagation of this rootstock by tissue culture results in many limitations such as shoot tip necrosis (stn) and a low proliferation rate. there...
objective(s):blactx-mand blaper are two genes that encode class a extended-spectrum β-lactamases (esbls) and can be responsible for therapeutic problems. this study was carried out to evaluate the molecular properties of these genes in clinical isolates of enterobacteriaceae by polymerase chain reaction (pcr), restriction digestion and sequencing. materials and methods: during six months, start...
background: breast cancer is the most common cancer in women, containing approximately one third of all illnesses in women. assessment of molecular markers is valuable in predicting the outcome of disease and decision making for optimal treatment. the purpose of this study was to determine the relationship between estrogen and progesterone receptors with her-2, ki67, p53, and clinicopathologica...
our aim in this work is the synthesis and study optical and structural properties of gold nanoparticles.gold (iii) chloride trihydratewas taken as metal precursor, ascorbic acid at the presence of an appropriate amount of naoh as reducing agent and polyvinylpyrrolidonek-30 (pvp k-30) as a stabilizing and capping agent. the reaction was performed in high-speed stirring rate at room temperature.s...
mercury is quantitatively retained with 1, 5-diphenylcarbazone (dpc) on microcrystallinenaphthalene in the ph range 6.5-8.5 from a large volume of aqueous solutions of various samples.after filtration, the solid mass consisting of the mercury complex and naphthalene was dissolvedin 5.0 ml of dimethylformamide (dmf) and mercury was determined by spectrophotometricmethod at 542 nm against the rea...
in this work, zncao2 (zinc oxide-calcium oxide) nanocomposite were synthesized at different temperatures (500-700°c) by sol-gel method based on polymeric network of polyvinyl alcohol (pva). the synthesized samples were characterized by sem/edax, ft-ir and xrd techniques. it was found that synthesized nanocomposites have 1.62, 2.05 and 13.91%wt of cao, respectively. the obtained results show tha...
background: the cuprizone multiple sclerosis (ms) animal model is characteristic for toxic demyelination and represents a reversible demyelination and remyelination system. it has been shown that green tea epigallocatechin-3-gallate (egcg) might be effective in improving the symptoms and pathological conditions associated with autoimmune inflammatory diseases in several animal models. objective...
در این تحقیق به دو روش استنباطی- تحلیلی و وزنی، رابطه بین مولفه های ژئومرفولوژی با منبع آب زیرزمینی دشت ذهاب واقع در مغرب استان کرمانشاه مورد بررسی و تحلیل قرار گرفته است. در روش اول، با استفاده از داده های چاه های اکتشافی و پیزومتری، تغییرات سطح آب زیرزمینی دشت ذهاب با عناصر ژئومورفولوژی این دشت مورد ارزیابی مقایسه ای قرار گرفته است و در روش دوم نیز با استفاده از تلفیق 7 متغیر: شیب، زمین شناسی...
introduction during the process photodynamic therapy (pdt), bleaching of photosensitizer induced by irradiation and generation of reactive oxygen species (ros) can provide some information concerning the efficiency of treatment. since gold nanoparticles (gnps) have been highlighted as efficient drug delivery systems, in this study, by utilizing gnps conjugated with 5 aminolevulinic acid (5-ala-...
nano-zeolite coapo-5 as a member of afi family, was synthesized via a hydrothermal treatment, and structurally characterized using x-ray diffraction (xrd), scanning electron microscope (sem), and energy dispersive x-ray analysis (edax). the effects of crystallization temperature and time on the structure of these powder products were studied. xrd patterns of the synthesized powders revealed a h...
