Objectives: To evaluate quantitatively cytokeratin and vimentin staining in glandular and stromal cells of eutopic and ectopic endometrium. DESIGN: The investigation of cytokeratin and vimentin was carried out using the new computerized technology of image analysis. SETTING: University Hospital, Department of Gynecology. PATIENTS: Biopsies were taken from patients undergoing a laparoscopy for infertility (29 endometrial biopsies and 31 biopsies of peritoneal endometriosis). None of them were treated. RESULTS: Cyclic variations of cytokeratin and vimentin staining were noted in eutopic endometrium. The cytokeratin and vimentin staining pattern consistently was lower in ectopic endometrium than in eutopic endometrium. CONCLUSIONS: Endometriotic epithelial and stromal cells undergo a complex program of differentiation giving them histochemical characteristics similar to those observed in endometrium. Such a concomitant expression of antigenicity indicates their close relationship with their mesodermal müllerian origin. [less ▲]

DNA ligases are important enzymes required for cellular processes such as DNA replication, recombination, and repair. NAD(+)-dependent DNA ligases are essentially restricted to eubacteria, thus constituting an attractive target in the development of novel antibiotics. Although such a project might involve the systematic testing of a vast number of chemical compounds, it can essentially gain from the preliminary deciphering of the conformational stability and structural perturbations associated with the formation of the catalytically active adenylated enzyme. We have, therefore, investigated the adenylation-induced conformational changes in the mesophilic Escherichia coli and thermophilic Thermus scotoductus NAD(+)-DNA ligases, and the resistance of these enzymes to thermal and chemical (guanidine hydrochloride) denaturation. Our results clearly demonstrate that anchoring of the cofactor induces a conformational rearrangement within the active site of both mesophilic and thermophilic enzymes accompanied by their partial compaction. Furthermore, the adenylation of enzymes increases their resistance to thermal and chemical denaturation, establishing a thermodynamic link between cofactor binding and conformational stability enhancement. Finally, guanidine hydrochloride-induced unfolding of NAD(+)-dependent DNA ligases is shown to be a complex process that involves accumulation of at least two equilibrium intermediates, the molten globule and its precursor.

First- (L1) and second-language (L2) lexical development has been found to be strongly associated to phonological processing abilities such as phonological short-term memory (STM), phonological awareness and speech perception. Lexical development seems also to be linked to attentional and executive skills such as auditory attention, flexibility and response inhibition. The aim of this four-wave longitudinal study was to determine to what extent L2 vocabulary acquired through the particular school context of early L2 immersion education is linked to the same cognitive abilities. Sixty-one French-speaking 5-year-old kindergartners who had just been enrolled in English immersion classes were administered a battery of tasks assessing these 3 phonological processing abilities and 3 attentional/executive skills. One, two and three school years later, their English vocabulary knowledge was measured. Multiple regression analyses showed that, among the assessed phonological processing abilities, phonological STM and speech perception, but not phonological awareness, appeared to underlie L2 vocabulary acquisition in this context of an early L2 immersion school program, at least during the first steps of acquisition. Similarly, among the assessed attentional/executive skills, auditory attention and flexibility, but not response inhibition, appeared to be involved during the first steps of L2 vocabulary acquisition in such an immersion school context.

Early bilingualism acquired from home or community is generally considered to positively influence cognitive development. The purpose of the present study was to determine to what extent bilingualism acquired through a second-language immersion education has a similar effect. Participants included a total of 106 French-speaking 8-year-old children drawn from two language groups: 53 children enrolled in English immersion classes since the age of 5 (the immersion group) and 53 children enrolled in monolingual French-speaking classes (the monolingual group). The two groups were matched for verbal and nonverbal intelligence and SES. They were administered a battery of tasks assessing attentional and executive skills. The immersion group’s reaction times were significantly faster than those of the monolingual group on tasks assessing alerting, auditory selective attention, divided attention and mental flexibility, but not interference inhibition. These results show that, after only 3 years, a second-language immersion school experience also produces some of the cognitive benefits associated with early bilingualism. [less ▲]

The purpose of this article is to assert the current state of the scientific literature on the issues regarding empathy in alcohol-dependents patients (ADs). We will first explain what the term « empathy » covers and the distinction made between cognitive and emotional empathy. We will describe then the different studies that got interested in the capacities for empathy in ADs patients. These studies concern predominantly one precise aspect of cognitive empathy: the capacity to infer an emotional state on the basis of emotional facial expressions (EFEs). Up to now, the other domain of cognitive empathy –the decoding of affective prosody and of nonverbal mulimodal stimuli and the attribution of intentions and beliefs– and emotional empathy are under-investigated in alcohol-dependence. In this review of the literature, we will identify the consequences that empathy problems could have on interpersonal relationships as well as the domains that still have to be to investigate regarding empathy in ADs patients, and notably the remediation of these deficits.
