Radiolabelling of Drosophila Embryos
Nature New Biology, 1973THE potential of Drosophila melanogaster for the study of embryonic development is unparalleled by any higher organism owing to the availability of numerous mutations that modify embryogenesis1-3. Knowledge about biochemical events during embryogenesis is limited, however, owing to the small size of the embryo and its impermeability to exogenous radio ...

Cytokines are soluble factors that act as intercellular messenger between cells of the immune system. They act by binding to specific receptors that are normally poorly expressed on effector cells but in disease are upregulated following cell activation.

Intracoronary radiolabeled particulate imaging
Seminars in Nuclear Medicine, 1980Intracoronary particulate imaging can delineate resting regional myocardial blood flow distribution patterns and differentiate ischemia from fibrosis in patients with stress thallium defects. Particulate imaging indicated 44 of 83 stress thallium defects to persist and 39 to resolve at rest. Areas of myocardium with normal stress perfusion or transient

Radiolabeled choline as a proliferation marker: Comparison with radiolabeled acetate
Nuclear Medicine and Biology, 2004[11C]Choline is a potential tracer to detect tumors, especially brain and prostate cancers. The metabolism of [11C]choline defines the accumulation pattern of [11C]choline in tumors depicted by positron emission tomography. Choline is a precursor of phosphatidylcholine that is a major constituent of membrane lipids.

Nuclear Medicine Communications, 1995
Designed by nature for stimulating, inhibiting or regulating numerous life functions, for a long time peptides have been considered ideal agents for therapeutic applications. In recent years, radiolabelled peptides have emerged as a new, useful class of radiopharmaceuticals for diagnosis of a variety of endocrine tumours. Although clinical results with

Radiolabeling of Angiotensin Peptides
2003The use of radioiodinated angiotensins has contributed greatly to our knowledge of the renin-angiotensin system (RAS). This chapter provides brief descriptions of the application of radioiodinated angiotensins and other radioiodinated compounds to study the RAS and the issues that must be considered when using radioiodinated angiotensins.

Imaging with radiolabelled bisphosphonates
Bone, 2020Radiolabeled bisphosphonates were developed in the 1970s for scintigraphic functional imaging of the skeleton in benign and malignant disease. Tracers such as 99mTc-methylene diphosphonate, that map focal or global changes in mineralization in the skeleton qualitatively and quantitatively, have been the backbone of nuclear medicine imaging for decades.

Radiolabeled Leukocytes and Platelets
Investigative Radiology, 1986Radiolabeled blood cells are widely used for both clinical and research studies. In vitro and in vivo studies have shown the tagging process does not significantly affect function. The labeling techniques and clinical uses of labeled leukocytes and platelets are reviewed.
