| metabolism of [5-t]fructose by isolated liver cells. | glucose formed from [5-t]fructose in rat hepatocytes contains about 10 to 30% tritium. this does not appear to be due to fructose metabolism via hexokinase since neither the initial presence of glucose, nor wide variations in the original fructose concentration, have much effect on the relative labeling of glucose versus water from [5-t]fructose. comparison of the t:14c ratios in glucose produced from [u-14c, 5-t]fructose and d-[u-14c, 2-t]glyceraldehyde indicate that there is tritium retention ... | 1975 | 1184583 |
| effects of cholera toxin on adenylate cyclase. studies with guanylylimidodiphosphate. | similarities exist between the properties of adenylate cyclase after stimulation by cholera toxin and after stimulation by guanylylimidodiphosphate (gpp-(nh)p). thus a strong stimulation is achieved by both agents, the stimulation is essentially irreversible, the action of certain hormones is enhanced and the enzyme can be solublized with lubrol px in the activated state. because of these similarities the interaction of cholera toxin and gpp(nh)p on adenylate cyclase was examined. it was found t ... | 1975 | 1184756 |

| selective inhibition of cholera toxin- and catecholamine-stimulated lipolysis by blocking agents. | vibrio cholerae enterotoxin stimulates lipolysis in rat epididymal fat cell suspensions. like hormones this toxin increases adenylate cyclase activity, raising levels of cyclic adenosine 3',5'-monophosphate (camp), which activates a cellular lipase. using specific blocking agents, we studied the responses to the adrenergic lipolytic hormones epinephrine, norepinephrine, and isoproterenol, and to cholera toxin. all stimulators were used at 100 x threshold dose. propranolol (34 mum), a beta blocki ... | 1975 | 1193734 |
| malignant teratoma arising within a lipomeningocele. case report. | the authors report the case of an 11-year-old, neurologically normal girl, followed since birth for lipomeningocele, who developed a malignant teratoma within the lymbosacral lesion and presented with metastases to the lungs and groin. this rare occurrence is discussed from an embryological and management viewpoint. | 2005 | 1194945 |
