The formation of covalent isopeptide cross-links between cell surface protein molecules by the enzyme transglutaminase C influences cell adhesion and morphology. Retinoid-inducible cross-linking activity associated with this enzyme is present in the developing rat cerebellar cortex [Perry M. J. M. et al. (1995) Neuroscience 65, 1063-1076]. A monoclonal(More)

A young patas monkey was run on a treadmill for 15-20 min at speeds in excess of 15 km times h-1 over a range of laboratory air temperatures from 0 to 55 degrees C. Cost of locomotion for the monkey was 83% that predicted for a running mammal of similar weight, 4 kg. At the highest steady-state running of speeds, the patas monkey's energy expenditure was 11(More)
A prospective study was undertaken to compare the diagnostic accuracy of clinical evaluation, ultrasound, computed tomography, and technetium 99m-HIDA or -PIPIDA biliary scans in distinguishing between intrahepatic and extrahepatic jaundice. A final diagnosis was established in each of the 50 patients who completed the study, among whom 29 had intrahepatic(More)
Covalent cross-linking of cell surface proteins by the calcium-dependent enzyme transglutaminase C may be implicated in cell-cell interactions and growth regulation. We demonstrate the presence of the enzyme in rat cerebellar cortex during postnatal development. Transglutaminase C was induced in cerebellar granule neurons in culture by retinoic acid,(More)
Midkine is a prominent acyl donor substrate for the protein cross-linking enzyme transglutaminase type 2 in rat brain neurons. Transglutaminase type 2 and midkine immunoreactivity are regionally colocalized in developing cerebellar cortex. Monomeric midkine is present in the embryonic dorsal rhombic lip which gives rise to the cerebellar cortex. A(More)
Hypoglycemia in fulminant hepatic failure and hyperinsulinemia in cirrhosis are well-described phenomena. A patient with alcoholic cirrhosis who developed fasting hypoglycemia with an extremely high immunoreactive insulin level and a mildly elevated C-peptide level is reported. An insulinoma was excluded by detailed radiological imaging of the pancreas and(More)
