Calcination Improves the In Vivo Efficacy of a Montmorillonite Clay to Bind Aflatoxin G1 in Broiler Chickens: A Toxicokinetic Approach.

The goal of this study was to investigate the toxicokinetic characteristics of aflatoxin G1 (AFG1) in broiler chickens and the effect of calcination of a Tunisian montmorillonite clay on the in vivo absorption of AFG1. In this study, broiler chickens were randomly distributed into four groups of 10 animals. Group 1 was administered AFG1 (2 mg/kg body weight (BW)) by single intravenous injection (IV), group 2 received an intra-crop bolus (PO) of AFG1 without any clay, group 3 was dosed AFG1 PO together with an oral bolus of purified clay (CP), and group 4 received AFG1 PO with an oral bolus of calcined clay.

Calcination Enhances the Aflatoxin and Zearalenone Binding Efficiency of a Tunisian Clay.

Clays are known to have promising adsorbing characteristics, and are used as feed additives to overcome the negative effects of mycotoxicosis in livestock farming. Modification of clay minerals by heat treatment, also called calcination, can alter their adsorption characteristics. Little information, however, is available on the effect of calcination with respect to mycotoxin binding.

[Postnatal depression and relationship with the cultural world in Tunisia].

Culture and the human spirit gain structure through their interactions with the cultural system. Indeed, individuals come from a culture which is unique to them and leaves its mark on them. In Tunisian concept, the young mother suffering from postnatal depression is considered to be possessed by the djinn spirit Kattous in-nfâs and treated using traditional rituals.

[Contrast-induced nephropathy after cardiac catheterization: a prospective study of 180 patients].

Background: Contrast-induced nephropathy (CIN) is associated with an increased cardiovascular morbi-mortality. Little is known about the incidence and risk factors of CIN after cardiac catheterization in Tunisian patients.

Aim: To determine the incidence of CIN and its predictors after coronary angiography as well as its prognostic and therapeutic repercussions in a Tunisian patients' cohort.
