Then, using the methods of abdominal writhing induced by acetic acid and nociceptive stimulus induced by formalin, it was verified that C. sabulicola presents analgesic activity.

In view of the above, the present study aims to evaluate the influence of maternal body mass index on the serum concentration of vitamin D in pregnant women. A systematic review was carried out with meta-analysis, subsidized by PRISMA norms. To do so, we searched the PubMed / Medline, Web of Science, Scopus, Science Direct, Ovid and Lilacs databases published between December 30, 1990 and June 30, 2018. The descriptors used were: "vitamin D", " "Body mass index", "obesity" and "pregnancy". The eligible articles were read in full, and subsequently collected variable information investigated in a form designed for the collection of the information. According to the eligibility criteria, 2951 studies were identified and 9 were selected to make a systematic review with meta-analysis and a meta-analysis was performed. Pregnant women with obesity and overweight presented a greater chance of vitamin D deficiency and insufficiency, when compared with pregnant women of normal weight. Thus, weight gain during pregnancy needs to be monitored in order to prevent vitamin D deficiency and complications to maternal and neonatal health.</em></p> 2019-07-24T11:21:59-03:00 Copyright (c) 2019 Pesquisare - A Revista Eletrônica da UFOB https://revistas.ufob.edu.br/index.php/pesquisare/article/view/528 Fatores socioeconômicos e prevalência de sintomas depressivos em gestantes do município de Barreiras, Bahia 2019-08-07T09:22:26-03:00 Cristiayne R.

However, in recent years, the use of colorimetric chemosensors for the determination of metal ions has been highlighted. Thus, in this work was demonstrated the applicability of a new Schiff base, 5-bromo-2-salicyliden-beta-alaninate, as a colorimetric chemosensor for spectrophotometric determination of copper(II) in a sample of artisanal cachaça, whose content was 0.53 mg L-1, which is in compliance with current legislation.

F. Silva eles266@eles.br Tânia A. Kuhnen eles267@eles.br <p><em>Based on the theoretical paradigm of ecofeminism, this paper addresses the women social movement called Marcha das Margaridas. Ecofeminists writers, such as Vandana Shiva and Maria Mies, start from a critical perspective of the Western development model, which is dependent on the exploitation and domination of nature. This model reflects the patriarchal paradigm that structures social and political organization in order to subordinate women. Considering the interrelation between nature and women domination, it is possible to remark, on the one hand, that children and women themselves have been more negatively impacted than men by the ecological disasters and by environmental degradation. On the other hand, women were the first one to protest against environmental destruction and to organize themselves to promote alternative development modes based on solidarity and cooperation. The main aim of this work is to analyze the social movement of women Marcha das Margaridas, its foundations and purposes in terms of social development and promotion of autonomy for peasant women, in light of the theoretical assumptions of the ecofeminist paradigm.

With these considerations, we evaluated the turbulence after passing through the turbine. Due to the consideration of the static rotor, we then observe each parameter varying from 0º to 120º (varying each 10º) the clockwise rotation of the turbine.
