introduction: optimized production and quality control of 68ga-dotatate as an efficient and preferable pet radiotracer for somatostatin receptor imaging in neuroendocrine tumors is of great interest. in this study effort has been made to present a fast, efficient, cost-effective and facile protocol for 68ga-dotatate productions for clinical trials. methods:68ga-dotatatewas prepared using genera...

BACKGROUND Tuberculosis (TB) indicators in South Africa currently remain well below global targets. In 2008, the National Tuberculosis Program (NTP) implemented a community mobilization program in all nine provinces to trace TB patients that had missed a treatment or clinic visit. Implementation sites were selected by TB program managers and teams liaised with health facilities to identify pati...

Background: Oxytocin (OT) is a paracrine hormone with various biological activities and many sex organs in both sexes, as well as many tumor cells have shown to have related receptors. In this study the development of a receptor imaging tracer for possible tumor imaging has been described. Materials and Methods: OT was successively labeled with [67Ga]-gallium chloride after conjugation with fre...

various radiometal complexes have been developed for tumor imaging, especially ga-68 tracer. in the present study, the development of a radiogallium bis-thiosemicarbazone complex has been reported. [67ga] acetylacetonate bis(thiosemicarbazone) complex ([67ga] aats) was prepared starting [67ga]gallium acetate and freshly prepared acetylacetonate bis (thiosemicarbazone) (aats) in 30 min at 90°c. ...

Rats were injected intravenously with various particulate materials with and without the addition of various stabilizing agents. One hour after the injection of the blockading colloid, a tracer dose of similar or different colloidal material was injected. A half-time clearance rate of the tracer dose greater than 4 minutes was taken as evidence of blockade of the RES. Blockade of the tracer dos...

We present a powerful diagnosis tool for the IEEE Std.1596 Scalable Coherent Interface (SCI): the SCI Tracer. The purpose of the SCI Tracer is to acquire data and analyze the activities on SCI links. The SCI Tracer consists of a hardware module and a software environment. The hardware is implemented in a multi-board module matching the Double Europe VME standard. It evaluates the flag bit in SC...

One of the most important requirements for industrial pipelines is the leakage detection. In this paper, detection of leak and determination of its amount using radioactive tracer injection method has been simulated by Monte Carlo MCNP code. The detector array included two NaI (Tl) detectors which were located before and after the considered position, measure emitted gamma from radioactive trac...

Tracer-tracer relations have been used for a long time to separate physico-chemical change from change caused by transport processes. In particular, for more than a decade, ozone-tracer relations have been used to quantify chemical ozone loss in the polar vortex. The application of ozone-tracer relations for quantifying ozone loss relies on two hypotheses: that a compact ozone-tracer relation i...
