We present a 55-year old male patient who was subjected to whole body skeletal scintigraphy for metastatic work up of urinary bladder cancer. Whole body 99mTc-methylene diphosphonate (MDP) skeletal scintigraphy was performed. That revealed no skeletal metastasis in the entire body skeleton and normally visualized left kidney with empty right renal fossa. Additionally tracer activity ...

Despite the fact that approximately 90% of patients with multiple myeloma present themselves with skeletal complaints (1, 2), few studies of bone mineral metabolism in this disease have been reported. Stable calcium studies in multiple myeloma were first reported in the literature by Blatherwick (3) in 1916. Since that time there have been only infrequent reports using balance techniques, or is...

-Frequent toxicant analyses are essential for good quality data in long-term continuous-flow tests. Due to the time consuming and costly chemical analyses, exposure levels are measured at best on a daily basis. These infrequent determinations may not detect variability in toxicant concentrations that could result in test failures. To minimize repetitive testing and improve data quality, a dye t...

TRACER TECHNIQUES FOR THE STUDY OF HOST-PARASITE RELATIONS. Autoradiographic techniques have been used to study the interaction of many facultative and obligate parasites, including viruses. After feeding the host plant with labelled substrates, labelled material accumulates in the infected cells and seems to penetrate into structures of the parasite. After labelling the parasite, its influence...

Complete sequencing of the oligosaccharide units of glycoproteins can be performed by conventional physical techniques if nanomole quantities of pure molecules are available. However, isolation of sufficient quantities of a glycoprotein may not be technically feasible (e.g., the analysis of biosynthetic intermediates, or rare molecules). Alternatively, partial structural analyses may answer the...
