Since statistical analysis proved the intercorrelation of tissue-gas partition coefficients of chemicals with similar chemical structures, bioavailability is controlled by one parameter dependent on the physicochemical properties of the chemicals and two constants distinguishing the tissues. Oil-gas partition coefficients are suggested to describe the(More)
Heme-oxygenases (HOs) catalyze the conversion of heme into carbon monoxide and biliverdin. HO-1 is induced during hypoxia, ischemia/reperfusion, and inflammation, providing cytoprotection and inhibiting leukocyte migration to inflammatory sites. Although in vitro studies have suggested an additional role for HO-1 in angiogenesis, the relevance of this in(More)
Assessment of the potential health hazard of environmental complex chemical mixtures is one of the most difficult and challenging problems in toxicology. In this article, we describe the development of an innovative computerized system for ranking and predicting potential cancer hazard of chemical mixtures. We take into consideration both the additive risk(More)
beta-adrenergic receptors (beta-ARs) were identified in CG-5 breast cancer cells using a radiometric assay. The total beta-AR concentration was measured using the highly potent beta-adrenergic antagonist (-)[3H]CGP 12177, and the densities of beta-AR subtypes were discriminated in the presence of highly selective unlabelled ligands (CGP 20712A and ICI(More)
Correlations between anti-neoplastic activity of medroxyprogesterone acetate (MPA), on the one hand, and serum prolactin (PRL) levels as well as tumour PRL and insulin receptor content, on the other, were investigated in female rats bearing dimethylbenzanthracene (DMBA)-induced mammary tumours. Changes in liver PRL receptor concentrations were also studied.(More)
In order to gain further knowledge about the possible oestrogen-like activities of clenbuterol (a beta 2-adrenergic drug illegally used as partitioning agent in food producing animals), we treated a hormone dependent human breast cancer cell line (CG-5) with different concentrations of the drug (10(-3) M to 10(-8) M). The effects of clenbuterol and(More)
Biologically and clinically relevant animal models are essential in investigation of the progression of diseases and the elaboration of diagnostic or therapeutic protocols. The several rodent models used for in vivo evaluation for oral cancer employ chemical, transplantation and genetic (knockout and transgenic) induction methods. These models are described(More)
