1. In vitro generation of human monocyte-derived dendritic cells methodological aspects in a comprehensive review
Abstract: Dendritic cells (DCs) initiate and shape both innate and adaptive immune responses. They are specialized in antigen presentation to naive T cells, thereby orchestrating the T cell immune responses. Human peripheral blood and tissues contain several subsets of phenotypically and functionally distinct DCs, which promote interactions between the exter

2. Intrafollicular barriers and cellular interactions during ovarian follicle development
Abstract Follicles are composed of different interdependent cell types including oocytes, cumulus, granulosa, and theca cells. Follicular cells and oocytes exchange signaling molecules from the beginning of the development of the primordial follicles until the moment of ovulation. The follicular structure transforms during folliculogenesis; barriers form bet

3. BINARY CO-CULTURE SELECTION FROM MARINE-DERIVED MICROORGANISMS FOR DIFFERENTIAL PRODUCTION OF SPECIALIZED METABOLITES
Nowadays the discovery of new compounds from microorganisms has substantially decreased. Genomic studies have shown that certain genes are not expressed under standard laboratory conditions. In order to overcome this problem, several methods including microorganism co-culture have been developed. The aim of this work was to select binary co-cultures of marin

4. Sentimentos do Estudante de Medicina quando em Contato com a Prática
RESUMO Com a atual configuração curricular dos cursos de Medicina, desde o primeiro ano do curso o estudante entra em contato com os serviços do Sistema Único de Saúde (SUS) e com a população usuária do sistema, o que costuma ser chamado de “contato precoce” com pacientes. Tal inserção precoce gera emoções diversas nos estudantes, positivas e

5. Functional specialization and phenotypic generalization in the pollination system of an epiphytic cactus
ABSTRACT Plant-pollinator interactions range from obligatory specialists to facultative generalists, and floral morphology and pollination system may not match completely. The floral biology, reproductive system and floral visitors of a species of the tribe Rhipsalideae were investigated with a focus on the consistency between the pollination system and the

6. The Role of Training in Shaping Pre-Service Teacher Cognition Related to L2 Pronunciation
Abstract This study analyzed changes in the pronunciation-related cognitions of undergraduate TESL students from two Canadian universities during their first term in their programs. The students from one university attended a 13-week course in phonology and pronunciation teaching, while those from the other university received no specific training in pronunc

7. The role of condensed tannins in ruminant animal production: advances, limitations and future directions
ABSTRACT Tannins represent one of the most abundant polyphenolic compounds in plants. Tannins exist as a multitude of chemically unique entities in nature. The most commonly occurring tannins are typically divided into two major classes based on chemical structure: hydrolysable (HT) or condensed tannins (CT). Hydrolysable tannins are esters of gallic or ella

8. Follicular helper T cell in immunity and autoimmunity
The traditional concept that effector T helper (Th) responses are mediated by Th1/Th2 cell subtypes has been broadened by the recent demonstration of two new effector T helper cells, the IL-17 producing cells (Th17) and the follicular helper T cells (Tfh). These new subsets have many features in common, such as the ability to produce IL-21 and to express the

9. Variation in plant-animal interactions along an elevational gradient of moist forest in a semiarid area of Brazil
Pollination and dispersal are critical ecological processes that directly affect the reproductive success of plants and are important for understanding the structure of plant communities. We compiled data on pollination and dispersal syndromes of 406 plant species distributed among different elevations in Área de Proteção Ambiental da Serra de Baturité (

10. Physiotherapy: a historical analysis of the transformation from an occupation to a profession in Brazil
ABSTRACTBackground:Analyzing the historical and social path of an occupation using the sociology of professions and the perspective of scientific knowledge promotes an understanding of the origin of physical therapy in Brazil and of discussions of the profession in its contemporary context.Objective: The aim of this paper was to discuss the professionalizati

11. Interações entre Protodiscelis (Colletidae, Neopasiphaeinae) e plantas aquáticas e a importância de odores florais na atração de polinizadores. / Interactions between bees of Protodiscelis (Colletidae, Neopasiphaeinae) and aquatic plants, and the importance of odors to locating flowers.
Abelhas são os principais polinizadores das plantas com flores. Plantas são sésseis e a reprodução sexuada cruzada somente ocorre através de vetores de pólen. Sendo assim, flores zoofílicas provêm pistas para o encontro interespecífico, são polinizadas e fornecem recursos florais aos polinizadores. O principal recurso coletado por abelhas herbívo

12. Mecanismos intraflagelares de transporte e trânsito de proteínas: uma abordagem pós-genômica e computacional de caracterização da virulência flagelar em Leishmania spp. / Intraflagelares mechanisms of transport and transit proteins: a post-genomics and computational characterization of virulence flagellar Leishmania spp.
Leishmania are flagellated protozoa that cause a main neglected diseasease, collectively known as leishmaniases, posing a constant challenge for the control and prevention of the disease due to the wide-world distribution and prevalence of these parasites. As an insinuating pathogen, Leishmania has a specialized organelle for motility, the flagellum, which i
