OBJECTIVES To develop a decision analysis based and computerised clinical guidance programme (CGP) that provides patient specific guidance on the decision whether or not to undergo a prophylactic oophorectomy to reduce the risk of subsequent ovarian cancer and to undertake a preliminary pilot and evaluation. SUBJECTS Women who had already agreed to have a hysterectomy who otherwise had no ova...

The beta-adrenergic receptors of isolated human fat cells were identified using a new hydrophilic beta-adrenergic radioligand (+/-)[3H]CGP-12177. The results were compared with those from [3H]dihydroalprenolol binding to fat cells and membranes. [3H]CGP-12177 binding to isolated fat cells showed lower nonspecific binding (less than 15% of total binding) than the lipophilic [3H]dihydroalprenolol...

To characterize the pharmacodynamic properties of CGP 69846A/ISIS 5132, an antisense oligodeoxynucleotide directed against the mitogenic signal transducer Raf-1 kinase, we investigated the elicited biological responses in human coronary artery smooth muscle cells. Cell exposure to CGP 69846A resulted in a reversible time- and concentration-dependent down-regulation of cellular Raf-1 gene expres...

Previous studies have indicated that inorganic and organic cations can markedly affect parameters of the function of the N-methyl-D-aspartate receptor ionophore complex. As these effects may involve modulation of agonist binding, the purpose of our study was to investigate the stimulatory effect of mono- and divalent cations on binding properties of glutamate/N-methyl-D-aspartate recognition si...

To investigate GABA(B) receptors along vagal afferent pathways, we recorded from vagal afferents, medullary neurons, and vagal efferents in ferrets. Baclofen (7-14 micromol/kg i.v.) reduced gastric tension receptor and nucleus tractus solitarii neuronal responses to gastric distension but not gastroduodenal mucosal receptor responses to cholecystokinin (CCK). GABA(B) antagonists CGP-35348 or CG...

BACKGROUND Positron emission tomography (PET) with 11C-labeled CGP-12177 (CGP) has been shown to have the potential to noninvasively measure beta-adrenergic receptor concentration in dog heart. The present study was undertaken to evaluate the clinical value of this technique. METHODS AND RESULTS Eight normal subjects and 10 patients with heart failure related to an idiopathic cardiomyopathy w...

We are reporting on the first human carcinoid cells ever cultured in vitro. These cells, termed CGP, originated from a jejunal carcinoid tumor. Before tumor resection, the 29-year old male patient presented high levels of blood serotonin and histamine and also of urinary serotonin and 5-hydroxyindole-acetic acid; values returned to normal 9 days after resection. CGP cells exhibit a very slow mu...

The archaeon Haloferax mediterranei was selected for production of PHA co- and terpolyesters using inexpensive crude glycerol phase (CGP) from biodiesel production as carbon source. CGP was assessed by comparison with the application of pure glycerol. Applying pure glycerol, a copolyester with a molar fraction of 3-hydroxybutyrate (3HB) of 0.90 mol/mol and 3-hydroxyvalerate (3HV) of 0.10 mol/mo...

Recently, researchers showed that dirty paper coding (DPC) is the optimal transmission strategy for multiple-input multiple-output broadcast channels (MIMO-BC). In this paper, we study how to determine the maximum weighted sum of DPC rates through solving the maximum weighted sum rate problem of the dual MIMO multiple access channel (MIMO-MAC) with a sum power constraint. We first simplify the ...

In this paper, a new approach to synthesize bent Boolean functions by means of Cartesian Genetic Programming (CGP) is proposed. Bent functions have important applications in cryptography due to their high nonlinearity. However, they are very rare and their discovery using conventional brute force methods is not efficient enough. We show that by using CGP we can routinely design bent functions o...
