Genetic Differences in Methionine Uptake by Surviving
ثبت نشده
چکیده
Two inbred strains of rats were compared as to their ability to incorporate methionine into surviving liver slices. The strains differed significantly in body weight and their reciprocal cross offspring showed marked heterosis. The J strain was built up from four females and two males of a single litter of the Wayne University Fisher line No. 344, with a pedigree of forty-five generations of sister and brother mating. The F strain was started from two pregnant females of the highly inbred King A inbred albino strain of the Wistar Institute and has been continued by sister and brother mating.

Discrimination of Single Transport Systems
Uptake of methionine, alpha-aminoisobutyric acid, and alpha-(methyl-amino)-isobutyric acid has been shown to occur by at least two transport systems, one sensitive and the other insensitive to the Na(+) concentration. For alpha-aminoisobutyric acid and its N-methyl derivative, the Na(+)-insensitive uptake is not concentrative and its rate increases almost linearly with concentration within the ...
متن کاملDiagnosis of Brain Tumors Using Amino Acid Transport PET Imaging With 18F- Fluciclovine: A Comparison Study With L-Methyl-11C-Methionine PET Imaging
Objective(s): 18F-fluciclovine (trans-1-amino-3-[18F] fluorocyclobutanecarboxylic acid, [FACBC]) is an artificial amino acid radiotracer used for positron emission tomography (PET) studies, which is metabolically stable in vivo and has a long half-life. It has already been shown that FACBC-PET is useful for glioma imaging. However, there have been no reports evaluating the efficiency of FACBC-P...
متن کاملEvaluation of primary brain tumors using 11C-methionine PET with reference to a normal methionine uptake map.
UNLABELLED (11)C-Methionine PET is a well-established technique for evaluating tumor extent for diagnosis and treatment planning in neurooncology. Image interpretation is typically performed using the ratio of uptake within the tumor to a reference region. The precise location of this reference region is important as local variations in methionine uptake may significantly alter the result, part...
متن کامل[11C]methionine PET, histopathology, and survival in primary brain tumors and recurrence.
BACKGROUND AND PURPOSE [(11)C]Methionine (MET) PET imaging is a sensitive technique for visualizing primary brain tumors and recurrence/progression after therapy. The aim of this study was to evaluate the relationship between the uptake of MET and histopathologic grading and to investigate the prognostic value of the tracer, in both settings. METHODS Cerebral uptake of MET was determined in 5...
متن کاملEvaluation of gill metabolites of Iranian sturgeon fingerlings Acipenser persicus at different levels of water salinity using HNMR method
Abstract In the present study, 180 Persian sturgeon fries at releasing weight with average weight of 1.8 ± 0.6 g were exposed to three different salinity levels including 0 (fresh water), 6 and 12 ppt in 96-hour and 10-day periods for measuring their gill metabolites by H-NMR based metabolomics. The results showed that changes in salinity caused changes in the metabolites involving in osmotic ...
