Thyroid-stimulating hormone (TSH) increased within 1 mm the adenyl cyclase activity of bovine and canine thyroid homogenate. A similar effect was also found when adenyl cyclase activity was measured in thyroid slices. In experiments in vivo, adenyl cyclase activity was augmented within 3 min after TSH injection, but this effect did not persist for 60 min after the injection. Despite the transie...

The effects of pancreatic hormones and cyclic AMP on the induction of ketogenesis and long-chain fatty acid oxidation were studied in primary cultures of hepatocytes from fetal and newborn rabbits. Hepatocytes were cultivated during 4 days in the presence of glucagon (106 M), forskolin (2 x 10'M), dibutyryl cyclic AMP (10-' M), 8-bromo cyclic AMP (10-' M) or insulin (10-' M). Ketogenesis and fa...

palladium nanoparticles supported on multi-walled carbon nanotubes (pd/mwcnts) have been synthesized using a modified polyol reduction method and its performance in methanol oxidation reactions has evaluated. the morphology of palladium on mwcnts was characterized by scanning electron microscopy (sem) and transmission electron microscopy (tem). the catalytic performance of synthesized catalyst ...

In this paper, the synergistic effects of stress rupture and cyclic loading on the strain response of fiber-reinforced ceramic-matrix composites (CMCs) at elevated temperature in air have been investigated. The stress-strain relationships considering interface wear and interface oxidation in the interface debonded region under stress rupture and cyclic loading have been developed to establish t...
