[Identity, culture and psychological discomfort: elements for a metacultural psychotherapy].

The purpose of this article is to offer observations and insights gained during the implementation of a specific Intervention Project and an experience of clinical work devoted to foreign people, including hot topics in the field of psychology and psychoterapy: the psychic discomfort of migrants. Today multiethnic and multicultural society that are urgently in the modern world is a reality that needs a more consistent focus and a complex response from psychiatry, psychology and science territorial similar. In the therapeutic relationship with an "other culture" the operator will adjust and restructure himself with great flexibility and particular sensitivity.

Estrogenic effect of procymidone through activation of MAPK in MCF-7 breast carcinoma cell line.

Procymidone modifies sexual differentiation in vitro and induces estrogenic activity in primary cultured rainbow trout hepatocytes, as shown by an increase in the contents of vitellogenin and heat shock proteins. Since this dicarboximide fungicide is found in human tissues, it was considered of interest to investigate its ability to induce endocrine damage in the MCF-7 human cell line. The mechanism of this estrogenic action was also evaluated.

Study of potential toxic effects on rainbow trout hepatocytes of surface water treated with chlorine or alternative disinfectants.

This study evaluates the effects of disinfection on the formation of toxic compounds in lake water treated with sodium hypochlorite, chlorine dioxide and peracetic acid (a disinfectant not previously used in drinking water processes). Chlorine reacts with the natural organic matter or contaminants in surface waters and produces a complex mixture of disinfection by-products (DBPs), some of which have been shown to be carcinogenic, mutagenic and/or teratogenic in animal studies. To define the potential toxicity on aquatic animals, disinfected drinking waters obtained from a pilot plant fed with water coming from Lake Trasimeno (Perugia) were collected, adsorbed by using silica C18 cartridges, and then eluted in sequence with ethylacetate, dichloromethane and methanol.

Estrogenic activity of procymidone in rainbow trout (Oncorhynchus mykiss) hepatocytes: a possible mechanism of action.

It is known that procymidone modifies sexual differentiation in vivo and in vitro, and that it induces vitellogenin (Vtg) synthesis in primary cultured rainbow trout hepatocytes. The aim of this study was to evaluate the mechanism underlying this latter in vitro estrogenic action. The cells were treated for 24 h with procymidone 150 microM (with 17beta-estradiol [E2] 20 microM as a positive control) combined with an estrogen receptor (ER) antagonist (tamoxifen 20 microM or ICI 182,780 1 microM) or, given the drug toxic action on the production of reactive oxygen species (ROS), a free radical scavenger (alpha-tocopherol 30 microM).
