Lead, copper, cobalt, nickel, iron and zinc ions form monocitrate complexes (negative charge) in citrate solution which is absorbed on the citrate form of anion-exchange resins (citrate as counter ion) y exchange of citrate ion with citrate complexes. These are subsequently recovered from the resin by 0.5M ammonium citrate eluent at pH 2.0. Under optimized conditions, quantitative recovery ...

National Center for Scientific Research “Demokritos”, Greece Gadolinium chelate coated gold nanoparticles (Au@DTDTPA) can be applied as contrast agents for both in vivo X-ray and magnetic resonance imaging. In this work, our aim was to radiolabel and evaluate this gold nanoparticle with Ga-68, in order to produce a dual modality PET/MRI imaging probe. For a typical preparation of 68Ga-labeled n...

Positron-emission tomography (PET) imaging enables cancer diagnosis at an early stage and to determine its pathological degree. However, tumor uptake efficiency of traditional PET radiotracers is usually low. Herein, we rationally designed a precursor CBT-NODA, the cold analogue CBT-NODA-Ga, corresponding radiotracer CBT-NODA-68Ga. Using these three compounds, verified that coinjection CBT-NODA...

background: clomiphene citrate (cc) an agonist and antagonist of estrogen, is the first line treatment in ovarian stimulation. anti-estrogenic effect of cc in endometrial thickness and cervical mucus has negative effect on pregnancy rate. letrozole is an aromatase inhibitor has been seen that has acceptable pregnancy rate compared to cc. objective: the aim of this study was to compare the effic...

in the present work, magnetic nanocomposites of the multi-walled carbon nanotubes (mwcnts) decorated with magnesium ferrite (mgfe2o4) nanoparticles were synthesized successfully by citrate-gel method. the shape, structure, size, and properties of the as-synthesized sample were characterized by fourier transform infrared spectroscopy (ftir), x-ray diffraction pattern (xrd), transmission electron...

this study was designed to compare the effect of clomiphene and letrozole in ovulatory stimulation in infertile women under intrauterine insemination who referred to mahdiyeh infertility clinic during 2008-2009. 106 infertile women were randomly divided into two equal groups. patients were treated with 5 mg of letrozole daily (in letrozole group) or 100 mg of clomiphene citrate daily (in clomip...

Localization of prostate cancer recurrence, particularly in the bones, is a major challenge with standard of care imaging in patients with biochemical recurrence following curatively intended treatment. Gallium-68-labeled prostate specific membrane antigen positron emission tomography/computed tomography (68Ga-PSMA PET/CT) is a novel and promising method for imaging in prostate cancer. The pres...

the effects of aluminium and aluminium-citrate on some serum parameters related to carbohydrate metabolism in male wistar rats were investigated. daily intraperitoneal administrations of 1 mg/kg body weight of aluminium or aluminiumcitrate (1: 1) for 50 days led to the elevation of serum insulin by 24 or 40 percent respectively, with the concomitant decrease in serum glucose concentrations by 1...

C-Met is a receptor tyrosine kinase that overexpressed in range of different cancer types, and has been identified as potential biomarker for imaging therapy. Previously, 68Ga-labelled peptide, [68Ga]Ga-EMP-100, shown promise c-Met renal cell carcinoma humans. Herein, we report the synthesis preliminary biological evaluation an [18F]AlF-labelled analogue, [18F]AlF-EMP-105, by positron emission ...
