Endocrine disruptors can affect the endocrine system without directly interacting with receptors, for example, by interfering with the synthesis or metabolism of steroid hormones. The aromatase that converts testosterone to 17-estradiol is a possible target. In this paper we describe an assay that simultaneously detects aromatase inhibition and estrogenicity. The principle is similar to that of other MCF-7 estrogenicity assays, but with a fixed amount of testosterone added. The endogenous aromatase activity in MCF-7 cells converts some of the testosterone to 17-estradiol, which is assayed by quantifying differences in the expression level of the estrogen-induced pS2 mRNA. Potential aromatase inhibitors can be identified by a dose-dependent reduction in the pS2 mRNA expression level after exposure to testosterone and the test compound. Using this assay, we have investigated several compounds, including synthetic chemicals and phytoestrogens, for aromatase inhibition. The phytoestrogens, except genistein, were aromatase inhibitors at low concentrations 1 M ; but estrogenic at higher concentrations 1 M ; , resulting in U-shaped doseresponse curves. None of the tested synthetic chemicals were aromatase inhibitors. The lowdose aromatase inhibition distinguished phytoestrogens from other estrogenic compounds and may partly explain reports about antiestrogenic properties of phytoestrogens. Aromatase inhibition may play an important role in the protective effects of phytoestrogens against breast cancer.

Prostate cancer is thus a major medicosocial problem comparable with that of breast cancer in women. In fact, it was predicted that 30 350 men will die from prostate cancer in the USA in 2005.

Baseline characteristics, past medical history, and medication profiles at the time of enrollment into the SOLVD trials were obtained from the SOLVD databases. Fasting plasma glucose FPG ; was not collected for research purposes in the SOLVD trials. However, the follow-up of our patients in SOLVD involved regular blood samples, including FPG, at almost every research visit. Accordingly, the medical file of each patient was reviewed, and FPG results were collected. Chart reviewers were blinded to treatment allocation. A diagnosis of new onset diabetes during the follow-up period was defined according to the American Diabetes Association criteria13 as a FPG 126 mg dL 7.0 mmol L ; at 2 different visits. For the purpose of the present study, we did not include the visits in which FPG 126 mg dL occurred during infection, trauma, or acute myocardial infarction. Participants with diabetes at baseline history of diabetes or FPG 126 mg dL at screening visit ; were excluded. We further divided our study population among patients with impaired FPG at baseline 110 mg dL [6.1 mmol L] FPG 126 mg dL [7.0 mmol L] ; and those with normal FPG at baseline FPG 110 mg dL.

For Salmonella, we are able to relate serotype with specific pathogenic properties and host specificity and apathogenic serotypes can also be recognised. Not so for C. jejuni. Although many serotypes have been identified, these do not correlate to host specificity or pathotype, and, at present, apathogenic C. jejuni strains have not been identified partly due to the lack of a suitable animal model ; . Similar findings are obtained when genetic variation, rather than phenotypic serotyping, is considered. Every genotyping method applied to C. jejuni has indicated a wide variety in genotypes. Yet, in contrast to the situation with Salmonella, in very few cases a correlation was found between genotype and serotype. Cluster analysis does not group out serotypes and a correlation between genotypes and host specificity, or between genotype and pathotype, is. Introduction The androgen receptor AR ; is a member of the family of steroid receptors. Functional ARs are required for development of the male gender Cunha et al., 1987 ; . In addition, ARs play a role in growth of prostate cancer Feldman and Feldman, 2001; Trapman, 2001 ; . Therefore, metastasized prostate cancers are frequently treated with antiandrogens, such as flutamide or bicalutamide Casodex ; Small and Vogelzang, 1997 ; . However, despite initial success, all patients eventually show tumour relapse. There may be several causes of therapy resistance, including changes in cell signalling pathways, AR overexpression and mutation of the AR Feldman and Feldman, 2001; Trapman, 2001 ; . The latter may lead to activation of the AR by ligands other than the androgens testosterone and 5 -dihydrotestosterone DHT ; , including estrogens, glucocorticoids and adrenal androgens Veldscholte et al., 1992; Brinkmann and Trapman, 2000; Zhao et al., 2000; Mizokami et al., 2004 ; . Therapy also selects for AR mutants that are activated by the applied antiandrogens Veldscholte et al., 1990; Hara et al., 2003 ; . One of the AR mutations most frequently found in antiandrogen-treated patients is a mutation in codon 877, resulting in the replacement of threonine by alanine AR T877A ; Veldscholte et al., 1990; Taplin et al and zovirax. Is still unclear how PI 3-kinase regulates the system of neurotransmitter release. Yang et al. 65 ; have shown that both PI 3-kinase and phospholipase C- pathways which induces the release of Ca2 from intracellular stores ; were necessary and sufficient to mediate neurotrophin-3-induced synaptic potentiation MAPK was not necessary ; . Furthermore, Amino et al. 66 ; showed the necessity of both PI 3-kinase and the MAPK pathways in nerve growth factor-enhanced dopamine release. All these findings including our study ; suggest the possibility that activations of several pathways are required for the potentiation of transmitter release. In the present study, we found that estradiol potentiated the release of glutamate induced by HK stimulation through the up-regulation of exocytotic machinery and that the concentration of estradiol is critical for this phenomenon. Does estrogen actually regulate synaptic transmission in vivo? As an example, the neuronal physiology of the female rat is known to fluctuate across the estrous cycle 6769 ; . In male rats, estradiol is synthesized from testosterone by aromatase P450 70 ; , which is expressed in various regions of the brain 71 ; , implying that estradiol was also effective in male brain. Sex steroids influence spatial memory, fear-related memory, and emotional behavior. For instance, it has been demonstrated that estrogen exerts energizing and antidepressant effects 72 75 ; , and progesterone, in contrast, inhibits kindling and seizure activity 46, 7678 ; . Furthermore, estrogen facilitates working memory in the radial-arm maze test and water maze task 79, 80 ; . Thus, although further examination is required, all these findings, including our own, indicate that ovarian steroids are an important factor in learning, memory, and emotional behavior.
