Abstract
Abstract
This is an account on the training of dental managers in a Social Welfare, not-for-profit, non-governmental institution present in all Brazilian states. Given the continental dimension of Brazil, its regional inequalities and the need for uniformity in the management conduct, as well as in the planning and evaluation of services, it is understood that developing managers' skills and competences is fundamental. Bearing in mind that the model adopted by the company is based on collective health, and its structure is organized in Primary Care, this proposal can be applied by other organizations that offer services of a similar nature. The aim of this study is to describe the training of oral health managers (n = 54) on the themes of sustainability, practices based on evidence/health economics and social determinants - themes that were requested by the managers themselves. Using problem-based learning, active and distance-learning methodologies, three working groups were set up among the managers to go through the contents of the training program, which aimed at training mentors and identifying successful service experiences for sharing. This process peaked at a face-to-face session with all participants where a specialist and their respective mentors presented each topic. The products obtained were: (1) three scientific-economic studies for decision making on the incorporation of hard technologies; (2) a guide to sustainable practices in dentistry and (3) a set of criteria for prioritizing access based on social determinants. In the evaluation of the training, 89% of managers were very satisfied, 8.98% were satisfied and 1.79% were dissatisfied. It is concluded that the methodology used in this process significantly contributed to the development of the company's regional service managers and such improvement stemmed from the empowerment, engagement and alignment of these managers, to which action plans were directed, with measures for monitoring and evaluation.
Key messages
Active methodologies in training contributes to the empowerment, engagement and alignment of dental managers before epidemiological, economic and social challenges faced in the management of services. Trainings where the participants are protagonists in all stages of the educational processes, are those that produce the best results and the highest degree of satisfaction among employees.

Abstract
The silverside (Odontesthes humensis) is a very interesting model for toxicological studies due its high sensitivity and need for good water quality. The aim of this study was to evaluate the effects of Roundup on spermatozoa of O. humensis, after acute exposure. The fish were exposed to 0 and 7.8 mg L-1 (a.e.) of glyphosate, respectively. Through computer-assisted sperm analysis, a significant decrease in concentration, total and progressive motility, average path distance, straight line distance, path average velocity, curved line velocity, straight line velocity linearity, wobble, amplitude of lateral head displacement, cross beat frequency, and motility period of silverside spermatozoa exposed to Roundup was observed. Also, increase in membrane fluidity, ROS production and lipid peroxidation and a decrease in the mitochondrial functionality was observed in spermatozoa of Roundup exposed silversides. It was demonstrated that Roundup exposure in a concentration that can be achieve in natural water bodies soon after its application in fields is able to cause losses in several sperm quality parameters, consequently decreasing the fertilization potential of O. humensis spermatozoa.

Abstract
Some mammalian reference genes, which are widely used to normalize the qRT-PCR, could not be used for this purpose due to its high expression variation. The normalization with false reference genes leads to misinterpretation of results. The silversides (Odontesthes spp.) has been used as models for evolutionary, osmoregulatory and environmental pollution studies but, up to now, there are no studies about reference genes in any Odontesthes species. Furthermore, many studies on silversides have used reference genes without previous validations. Thus, present study aimed to was to clone and sequence potential reference genes, thereby identifying the best ones in Odontesthes humensis considering different tissues, ages and conditions. For this purpose, animals belonging to three ages (adults, juveniles, and immature) were exposed to control, Roundup®, and seawater treatments for 24 h. Blood samples were subjected to flow-cytometry and other collected tissues to RNA extraction; cDNA synthesis; molecular cloning; DNA sequencing; and qRT-PCR. The candidate genes tested included 18s, actb, ef1a, eif3g, gapdh, h3a, atp1a, and tuba. Gene expression results were analyzed using five algorithms that ranked the candidate genes. The flow-cytometry data showed that the environmental challenges could trigger a systemic response in the treated fish. Even during this systemic physiological disorder, the consensus analysis of gene expression revealed h3a to be the most stable gene expression when only the treatments were considered. On the other hand, tuba was the least stable gene in the control and gapdh was the least stable in both Roundup® and seawater groups. In conclusion, the consensus analyses of different tissues, ages, and treatments groups revealed that h3a is the most stable gene whereas gapdh and tuba are the least stable genes, even being considered two constitutive genes.

Abstract
O estudo foi realizado com objetivo de avaliar os parâmetros fisiológicos de poedeiras alojadas em diferentes densidades de alojamento e períodos. Foram utilizadas 150 poedeiras Dekalb White com 20 semanas de idade alojadas em um galpão convencional com gaiolas metálicas com duas subdivisões de 50x45x40 cm2 e distribuídas em três tratamentos: 8 aves por gaiola (562,5 cm2/ave); 10 aves por gaiola (450 cm2/ave) e 12 aves por gaiola (375 cm2/ave), com cinco repetições cada. Avaliaram-se parâmetros fisiológicos (frequência respiratória, temperatura cloacal e temperatura superficial) e condições ambientais (temperatura ambiente e umidade relativa) durante três ciclos de 28 dias. Adotou-se um delineamento inteiramente casualizado com arranjo fatorial 3x3 (três densidades de alojamento e três períodos). Os resultados demonstraram que a densidade de alojamento não prejudicou a frequência respiratória e a temperatura superficial, porém, a temperatura cloacal diferiu significativamente, sendo superior às 16 horas e a densidade de alojamento com 10 aves/gaiola permaneceu intermediário às outras densidades. Os parâmetros voltados à busca do conforto térmico evidenciaram que nos horários mais quentes do dia (até as 16:00 horas), independente da densidade, as aves apresentaram temperaturas maiores que na parte da manhã.

Abstract
BACKGROUND AND AIMS Shining a laser onto biological material produces light speckles termed biospeckles. Patterns of biospeckle activity reflect changes in cell biochemistry, developmental processes and responses to the environment. The aim of this work was to develop methods to investigate the biospeckle activity in roots and to characterize the distribution of its intensity and response to thigmostimuli. METHODS Biospeckle activity in roots of Zea mays, and also Jatropha curcas and Citrus limonia, was imaged live and in situ using a portable laser and a digital microscope with a spatial resolution of 10 μm per pixel and the ability to capture images every 0.080 s. A procedure incorporating a Fujii algorithm, image restoration using median and Gaussian filters, image segmentation using maximum-entropy threshold methods and the extraction of features using a tracing algorithm followed by spline fitting were developed to obtain quantitative information from images of biospeckle activity. A wavelet transform algorithm was used for spectral decomposition of biospeckle activity and generalized additive models were used to attribute statistical significance to changes in patterns of biospeckle activity. KEY RESULTS The intensity of biospeckle activity was greatest close to the root apex. Higher frequencies (3-6 Hz) contributed most to the total intensity of biospeckle activity. When a root encountered an obstacle, the intensity of biospeckle activity decreased abruptly throughout the root system. The response became attenuated with repeated thigmostimuli. CONCLUSIONS The data suggest that at least one component of root biospeckle activity resulted from a biological process, which is located in the zone of cell division and responds to thigmostimuli. However, neither individual cell division events nor root elongation is likely to be responsible for the patterns of biospeckle activity.
