Given the increasing exploration of fluorescent tracers in the field of nuclear medicine, a need has risen for practical development guidelines that can help improve the translation aspects of fluorescent tracers. This editorial discusses the does and don'ts in developing fluorescence tracers. It has been put forward by the European Association of Nuclear Medicine (EANM) Translational Molecular...

soil erosion is one of the most destructive phenomena which cause significant ecological changes in many areas. soil conservation and erosion control is essential because of the irreparable damage caused by soil erosion. soil conservation programs will not achieve until to find adequate methods of combating land degradation and ways to reduce the sediment. therefore, we need to have enough know...

Ray tracers that render CSG models should consider issues of regularization and numerical accuracy. The special case of rays originating on surfaces (shadow probes, reflections, and refractions) present a regularization problem that is significant-even in ray tracers which are not explicitly based on the CSG scheme. An analysis of this problem yields a better solution than the epsilon tests inc...

O NLY A FEW YEARS after the discovery of artificial radioisotopes by the Joliot-Curies in 1934, de Hevesy, Chievitz and Ottesen used tracers in hematology. Even today, there are few areas in clinical medicine where as many radioisotopes are used both for investigative and diagnostic purposes as in hematology. Consequently, the methods of tracer studies are often described in the hematologic jou...

This paper provides a brief review of the radiochemistry of radiopharmaceuticals used in positron emission tomography (PET). It includes some history of PET, the basic formation of radionuclides in a cyclotron target, the processing of the precursor molecules into a useful PET radiotracer and the clinical significance and outlook for PET radiotracers. This review is based on a series of recent ...
