Tumor uptake studies of S-adenosyl-L-[methyl-11C]methionine and L-[methyl-11C]methionine.
Tumor accumulation of S-adenosyl-L-[methyl-11C]methionine ([11C]SAM) was investigated in mice bearing mammary carcinoma (FM3A) and in rats bearing ascitic hepatoma (AH109A). After injection of [11C]SAM the blood clearance of 11C radioactivity was rapid. The 11C level was relatively high in both tumors. The uptake ratios of tumor to organ increased with time in several organs, especially in brai...
متن کاملOntogeny of pancreatic exocrine function.
Exocrine pancreatic proteolytic activity, determined by serial measurement of faecal chymotrypsin concentration, was investigated in 21 preterm infants (23-32 weeks' gestation) during the first 28 days of life. The overall chymotrypsin concentration range was similar to that already described in term infants showing that pancreatic chymotrypsin secretion is equally well developed at birth in th...
متن کاملImproving the stability of 11C–labeled L-methionine with ascorbate
Background Carbon-11 labeled L-methionine (11C-MET) is a popular tracer used in the clinic for imaging brain tumors with positron emission tomography. However, the stability of 11C-MET in its final formulation is not well documented in literature. Recently, we observed fast degradation of HPLC-purified 11C-MET over time, and systematic investigation was conducted to identify the cause. Result...
متن کاملOntogeny of human pancreatic exocrine function.
At birth pancreatic exocrine function is far from mature and, like many other organ systems of the newborn, undergoes rapid development during early life. Knowledge of the functional capacity of the human pancreas during the perinatal period has important implications for the feeding of neonates, especially those born preterm or who are retarded in growth, and for making recommendations about t...

lary circulation and thereby reduces islet perfusion. Interestingly, in tropical countries and India a special form of non-alcoholic tropical calcifying pancreatitis leads to DM. Although little is known about the exact etiology of this form of diabetes it has been found that the -cell function is damaged whereas the cells are preserved [6, 7] . This is in contrast to the non-tropical chronic...
