13. Sobre anorexias e bulimias: concepções e suposições etiológicas na perspectiva dos profissionais de Saúde
Anorexias e bulimias são síndromes graves que requerem um manejo cuidadoso. A prática clínica e a literatura mostram, entretanto, que sua abordagem é, muitas vezes, inadequada. Neste estudo, interessou-nos conhecer o discurso dos profissionais de Saúde acerca da caracterização e etiologia desses quadros. Foram realizadas entrevistas semiestruturadas

14. Tomato seed image analysis during the maturation
Resumo: O potencial fisiológico das sementes está diretamente relacionado à normalidade do processo de formação delas, sob ponto de vista morfológico, estrutural e funcional. Deste modo, o objetivo deste trabalho foi avaliar a morfologia interna de sementes de tomate, híbrido BRS Nagai, em diferentes estádios de maturação, por meio da análise de i

15. Hyaluronic acid accelerates bone repair in human dental sockets: a randomized triple-blind clinical trial
Abstract This study evaluated the effects of hyaluronic acid (HA) on bone repair of human dental sockets. Thirty-two lower first premolars were extracted from 16 patients (2 per patient) for orthodontic reasons. Following the extractions, one socket was randomly filled with 1% HA gel, while the other was allowed to naturally fill with blood clot. After 30 an

16. Evaluation of bulk-fill systems: microtensile bond strength and non-destructive imaging of marginal adaptation
Abstract The objective of this study was to investigate microtensile bond strength (MTBS) and interfacial adaptation (IA) of bulk-fill restorative systems bonded to dentin in Class-I-preparations. Box-shaped preparations (4-mm-long, 3-mm-wide, 2-mm-high) made in extracted molars, and Teflon matrix with the same dimensions positioned over the occlusal surface

17. Structural, Optical and Thermal Characterizations of PVA/MAA:EA Polyblend Films
Films of polyvinyl alcohol (PVA), Methacrylic Acid - Ethyl Acrylate (MAA:EA) copolymer and their blends PVA:MAA:EA of composition 80:20, 60:40, 50:50, 40:60, 20:80 (wt %) were prepared by using the solution cast technique. The prepared films were investigated by structural, optical and thermal studies. X-ray diffraction (XRD) scans revealed the semicrystalli

18. Effects of platelet-rich plasma on human gingival fibroblast proliferation and migration in vitro
Abstract Objective This study evaluated the influence of platelet-rich plasma (PRP) on the behaviour of human gingival fibroblasts (hGFs), including fibroblast proliferation, migration and colony formation. Methods PRP was obtained from the human peripheral blood of a healthy volunteer and then was diluted into platelet concentrations of 1%, 2% and 5%. T

19. Photoacoustic-based thermal image formation and optimization using an evolutionary genetic algorithm
Abstract Introduction For improved efficiency and security in heat application during hyperthermia, it is important to monitor tissue temperature during treatments. Photoacoustic (PA) pressure wave amplitude has a temperature dependence given by the Gruenesein parameter. Consequently, changes in PA signal amplitude carry information about temperature varia

20. Discusión de la aproximación paraxial y análisis numérico de la aberración de esfericidad
Textbooks intended to undergraduate students discuss image formation by mirrors and lens based on paraxial approximation. This conventional approach has ambiguities and lacks which induce students to conceptual mistakes. This paper points out those ambiguities and demonstrates that a basic proposition of paraxial approximation has a very limited scope. Furth

21. Generation of a triple-fluorescent mouse strain allows a dynamic and spatial visualization of different liver phagocytes in vivo
ABSTRACT Resident and circulating immune cells have been extensively studied due to their almost ubiquitous role in cell biology. Despite their classification under the “immune cell department”, it is becoming increasingly clear that these cells are involved in many different non-immune related phenomena, including fetus development, vascular formation,

22. Mujeres delincuentes e imaginarios. Criminología, cine y nota roja en México, 1940-1950
ABSTRACT The political and economic modernization promoted by the governments in the aftermath of the Mexican Revolution created opportunities of development for women outside the domestic sphere. The specialization of criminology and the professionalization of the media, linked to an entrenched conservatism, were instrumental in the formation of a notorious

23. Occurrence of dermoid cyst in the floor of the mouth: the importance of differential diagnosis in pediatric patients
Abstract Lesions in the floor of the mouth can be a challenging diagnosis due to the variety of pathological conditions that might be found in this area. Within a broad range of lesions, attention has to be addressed to those that require specific management, such as a dermoid cyst (DC) and a ranula. Especially in pediatric patients, in whom the failure of d

24. Role of 1% alendronate gel as adjunct to mechanical therapy in the treatment of chronic periodontitis among smokers
Abstract Objective Alendronate (ALN) inhibits osteoclastic bone resorption and triggers osteostimulative properties both in vivo and in vitro, as shown by increase in matrix formation. This study aimed to explore the efficacy of 1% ALN gel as local drug delivery (LDD) in adjunct to scaling and root planing (SRP) for the treatment of chronic periodontitis a
