RSBO , 2010,
Abstract: Introduction: Nutritional and development variables both at birth and early age can predict the number of erupted teeth that children will have in their oral cavity. Objective: This study aimed to report the time and sequence of eruption of deciduous teeth in children from Itajaí city, comparing data regarding to teeth, gender, age, socioeconomic level,and breast-feeding. Material and methods: A cross-sectional study was performed with 1297 children divided by gender and age. In order to test the hypothesis that tooth eruption varies between males and females, t-test was comparatively applied. Results: It was observed an earlier male eruption time of tooth #61 (left upper central incisor), starting at 10.6 months and finishing at 30.9 months, with tooth #65 (left upper second molar). Female eruption time started with tooth #71 (left lower central incisor), at 12 months and finished at 31.55 months with tooth #85 (right lower second molar). The analysis of mean eruption values by t-test showed a contrast between genders for the following teeth: #63, #72, #73, and #83. Total male and female mean eruption time was 20.30 months and 19.95 months, respectively. It was observed that children who had been exclusively breastfed for over than six months, showed non-statistically significant greater mean eruption times Conclusion: Such values predict that both sequence andmean eruption time would be genetically determined. Environmental influences as breast-feeding type do not necessarily alter the eruption time means.

Abstract: depression is a disorder that may affect patient's weight because of specific factors of the disease, such as changes in appetite and in the level of physical activity, as well as because of the use of antidepressant medications. the objectives of this paper are to analyze studies that discuss the effect of antidepressant medications on the patients' weight. medline, lilacs and cochrane databases were searched for relevant studies using the words 'antidepressant' and 'weight'. publications regarding antidepressant drugs commonly used in health services in brazil and their effects on body weight in depressive patients were selected. the studies indicated that weight changes related to antidepressant therapies are still controversial, influenced by factors such as length and dosage of antidepressant use, limited power of the studies, among others. thus, more powerful studies focusing on how antidepressant medications affect weight in depressive patients are still needed.

DELTA: Documenta??o de Estudos em Lingüística Teórica e Aplicada , 2010, DOI: 10.1590/S0102-44502010000300009
Abstract: this work aims at presenting some results of the research developed in the project named metaphor, discursive genre and argumentation (mgda) which has the purpose of describing linguistic expressions that materialize conceptual metaphors in several discursive genres, searching for the identification of the semantic-discursive function(s) of such expressions. the researches were done by my students and me and the present results reveal some discursive functions not seen in the literature so far: the presence of metaphorical expressions that materialize conceptual metaphors with the function of approaching the advertiser to the interlocutor in publicity and linguistic expressions that literalize the everyday life conceptual metaphor, producing laughter in humor, among other semantic-discursive functions.
