A method is described for the enzymatic synthesis of 5’-adenylyl imidodiphosphate labeled with a2P at the a! position (AMP-PNP-cx-~~P), an analogue of ATP containing nitrogen substituted for oxygen between the terminal phosphates. The nucleotide is only slowly hydrolyzed during incubation with rat liver plasma membranes and is a substrate for adenyl cyclase(More)
Mitotane is considered to be the drug of choice for patients with inoperable, recurrent and metastatic adrenocortical carcinoma, although a favourable effect of this drug on survival has never been documented. We evaluated the efficacy of mitotane treatment of 96 patients with adrenocortical carcinoma followed up in our department between 1959 and 1992.(More)
OBJECTIVE To compare steroids and their associations in men with type 1 diabetes and healthy control subjects. RESEARCH DESIGN AND METHODS We studied 52 adult men with type 1 diabetes without microvascular complications, compared with 53 control subjects matched for age and BMI. Steroids and their binding globulins were assessed in a single venous blood(More)
Short-term exposure of tissues to pulses of insulin generally leads to an enhancement of insulin action. We have investigated the possible beneficial effects of long-term near-physiological continuous vs pulsatile intravenous insulin treatment of insulin-deficient streptozotocin (70 mg/kg) diabetic rats on blood glucose control, in vivo insulin action and(More)
In type II diabetes mellitus the altered hormonal state after menopause may represent an additional cardiovascular risk factor. Estrogen replacement therapy (ERT) is associated with a decreased cardiovascular risk, at least in nondiabetic postmenopausal women. We studied the effect of ERT on plasma lipids and lipoproteins and on LDL oxidation in 40(More)
Type 2 diabetes mellitus is frequently accompanied by hypercoagulability and hypofibrinolysis. Both are related to increased cardiovascular risk, but possibly with endothelial injury as well. Studies with nondiabetic persons indicate that unopposed oestrogen replacement therapy (oERT) decreases cardiovascular risk, possibly mediated in part by effects on(More)
Oestrogen replacement therapy is associated with a decreased risk of cardiovascular disease in postmenopausal women. Patients with non-insulin-dependent diabetes mellitus (NIDDM) have an increased cardiovascular risk. However, oestrogen replacement therapy is only reluctantly prescribed for patients with NIDDM. In a double blind randomized placebo(More)
The objective of this study was to present the long-term results of total adrenalectomy for Cushing's disease. Forty-four patients undergoing total adrenalectomy for Cushing's disease between 1953 and 1989 at Leiden University Medical Center, The Netherlands, were studied retrospectively. Remission was achieved in 42 patients (95%), with a mean duration of(More)
Amylin, also called islet amyloid polypeptide (IAPP), or diabetes-associated peptide (DAP) is a recently discovered 37 amino acid polypeptide which has been shown to be co-secreted with insulin from the pancreatic beta-cell. The peptide turned out to be the major constituent of pancreatic amyloid deposits which are frequently found in the pancreas of type(More)
