background: copper-64 (t1/2=12.7 h) is an important radionuclide used both in pet imaging and therapy. [64cu]-pyruvaldehyde-bis (n4-methylthiosemicarbazone) ([64cu]-ptsm) is one of the most famous copper radiopharmaceuticals with unique specifications (suitable half life, stability, etc.). the wide range of 64cu applications arouse great interest for its production. materials and methods: cu-64...
introduction: 64cu-pyruvaldehyde-bis(n4-methylthiosemicarbazone) (64cu-ptsm) is one of the most important copper radiopharmaceuticals used in clinical experiments. methods: in this work, copper-64 (t1/2=12.33 h) production has been presented followed by the synthesis of the complexing agent, ptsm, and its structure was confirmed by common spectroscopic methods followed by radiolabeling with 64...
background and purpose: cervical cancer is the most prevalent cancer among women in the world. cervical cancer is no symptoms and can be treated if diagnosed in the first stage of the disease. the aim of this study was to survey the affecting factors of the pap smears test on perceptual factors, enabling and reinforcing (pen-3) model constructs in women. materials and methods: this study was a ...

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...
patients and methods in a quasi-experiment trial, 40 type 2 diabetic patients were asked to consume 50 g of cpj daily for 4 weeks. anthropometric indices, dietary intake, blood pressure measurements, and fasting blood samples were conducted at baseline and 4 weeks after the intervention. results the intake of cpj produced a significant increase in both total and high-density lipoprotein cholest...
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...
conclusions the rapid dissemination of non clonal multi-resistant ctx-m-1 producing e. coli isolates approved the need for further studies in our medical centers. results a total of 140(70%) non-duplicate esbl positive e. coli were determined. imipenem and amikacin were effective against 100% and 85% of all tested isolates respectively. co-resistance of esbl positive isolates to erythromycin, t...
addition of n-butyl nitrite to isolated rat hepatocytes caused an immediate glutathione depletion followed by an inhibition of mitochondrial respiration, inhi- bition of glycolysis and atp depletion. at cytotoxic butyl nitrite concentrations, lipid peroxidation occurred before the plasma membrane was disrupted. cytochrome p-450 inhibitors inhibited peroxynitrite formation and prevented ...
in this study, a simple and low-cost method was developed for extraction and pre-concentration of brilliant blue(bb) and tropaeolin o(to) in food samples using cloud point extraction (cpe) prior to spectrophotometric determination. the effects of main factors such as ph, surfactant and salt concentrations, incubation time and temperature on the cloud point extraction of both dyes were investiga...
