title: Reviewing the use of IBGE data for research and land planning: reflections on the classification of the urban and rural situation

description: Abstract This article discusses the classification of census tracts, according to their urban or rural situation, proposed by the Brazilian Institute of Geography and Statistics (IBGE). The contributions that this classification brings to urban planning are explored, and the limits and possibilities of the use of these data to map the contemporary urban expansion and to structure the territory beyond the urban-rural divide are emphasized. Users of census information should know the method used by the IBGE to construct cartographic databases utilized during collection. In addition, users should reflect on how IBGE data can be employed in the construction of public policies, highlighting the relevance of the collected information and stressing the role of municipalities in initiatives to develop improved databases in order to obtain better results in the next census.

title: Evaluation of color stability of different temporary restorative materials

description: AbstractIntroductionTemporary restorative materials are widely used, however, little is know about their color stability.Objectiveto evaluate the color stability of the following temporary restorative materials: acrylic and bis-acrylic resins after immersion in pigmenting solutions for different periods of storage.Material and methodFour materials were tested (Dêncor/Clássico, Protemp 4/3M ESPE; Structur 2 SC/Voco; Luxatemp AM Plus/DMG) and 30 test specimens (15 mm in diameter and 2 mm thick) per material were fabricated. They were divided according to the storage medium (artificial saliva, saliva + cola type soda, and saliva + coffee) and storage time intervals (2, 5, 7 and 15 days). Color measurements were made before and after immersions, with use of a spectrophotometer, by means of the CIE L*a*b* system. The data were analyzed by the analysis of variance and the Tukey Test, at a level of significance of 5%.ResultAcrylic resin presented greater color stability in comparison with bis-acrylic resins (p&lt;0.001). When bis-acrylic resins were compared no significant difference was observed between the resins Structur and Luxatemp (p=0.767). As regards solutions tested, coffee showed the highest color change values (p&lt;0.001), and the longer the storage time interval, the greater was the color change in all the temporary restorative materials analyzed (p&lt;0.001).ConclusionAcrylic resin presented greater color stability in comparison with bis-acrylic resins (p&lt;0.001). Coffee caused the greatest color change, and immersion time was determinant in color stability of the temporary materials analyzed.

title: INFLUENCE OF STORAGE CONDITIONS OF INFLUENZA VIRUS ON VIRUS DETECTION BY RT-qPCR AND VIRAL ISOLATION

description: Abstract Influenza virus infection in pigs causes significant losses for the swine industry and concerns for the public health. Therefore, rapid virus detection is important for influenza surveillance in pigs. Storage conditions (such as medium, temperature, and time) of the biological samples are very important for the diagnosis because they can negatively interfere with the viral detection. In this study, influenza virus viability was evaluated in different storage media (UTM commercial medium, "in house" VTM medium, and without storage medium), temperature (4, 23 and 37 °C), and storage time (up to 120 hours). Samples were evaluated by RT-qPCR and isolation in embryonated chicken eggs. Significant effects (p&lt;0.05) were observed for the media and time besides the interaction between the two factors with the viral load. In conclusion, biological samples of pigs sent for influenza diagnosis should be stored, preferably in viral maintenance medium at 4 °C, and the time estimated between the sample collection until the arrival in the laboratory should be less than three days.

title: Patterns evaluation of the labial frenum's morphology and insertion on patients that attended the clinic school of dentistry of the University Center of João Pessoa - PB

description: AbstractIntroductionThe investigation of the structural patterns of labial frenum is important to establish the frequency with which variation occur, whether normal or harmful to the function.ObjectiveTo evaluate the patterns of morphology and insertion of labial frenum of patients attended at the clinical School of Dentistry of the University Center of João Pessoa-PB.Material and methodIt was evaluated 385 patients of both genders that attended the clinic between august 2012 and april 2013. The data was analyzed using SPSS (20.0) software.ResultThe most prevalent morphology was single for both the upper labial frenum (82.6%) and for the lower (100.0%). The insertion most prevalent is the “alveolar mucosa”, both in the upper (75.8%) and the lower (99.0%). There was no difference between males and females for morphology and superior insertion (p= 0.673; p=0.582, respectively), as well as to the lower insertion (p=0.599), and so on for the different skin colors (leucoderma, melanoderma e faioderma) (p=0.343; p=0.269; p=0.134, respectively). There was statistical difference (p=0.011) between the mean age for insertion variants of the upper labial frenum.ConclusionThe most common morphology for both upper labial frenum and for lower is simple, with a higher number of morphological variants to superiors; while the insertion of the alveolar mucosa is most common for both upper and lower frenum; there is no relationship between the morphology and patterns of insertion regarding gender and skin color, but there is relation between the pattern of insertion of the upper labial frenum and age.

title: Effect Of Resistance Training On Myocardial Contractility In Vitro After Sleep Deprivation

description: Abstract Background: Resistance training promotes cardiovascular health benefits that may affected by sleep deprivation. Objective: To evaluate the effect of high-intensity resistance training on myocardial contractility in rats subsequently subjected to paradoxical sleep deprivation. Methods: Forty male Wistar rats were distributed into control group (CTRL), resistance training (REST), 96-hour paradoxical sleep deprivation (PSD96) and resistance training followed by 96-hour paradoxical sleep deprivation (REST/PSD96). The animals underwent high-intensity resistance training for 8 weeks, 5x/week. Twenty-four hours after the last training session, the PSD96 and REST/PSD96 groups were submitted to paradoxical sleep deprivation, which was followed by the in vitro study of isolated papillary muscle contractile mechanics. Results: In comparison with the CTRL group, a lower papillary muscle length and increased cross sectional area were found in PSD96 and RETS/PSD96, which were associated with decreased temporal parameters of contraction force and relaxation. Decreased resting tension and slowing of relaxation time were found in the PSD96 group only. This effect was attenuated by previous resistance training. Conclusion: Resistance training partially prevented contractile changes induced by PSD, minimizing the slowing in relaxation time. Thus, high-intensity exercise seems to not fully protect the cardiac tissue from PSD-induced effects.

title: ANTIMICROBIAL ACTIVITY OF MICROORGANISMS ISOLATED FROM KEFIR GRAINS

description: Abstract Kefir is the product of milk fermentation by kefir grains. These grains contain a mixture of symbiotic bacteria and yeasts embedded in a matrix composed of polysaccharides and proteins. Many human health benefits have been attributed to kefir, including antimicrobial activity against Gram positive and Gram negative bacteria. We studied the antimicrobial activity of sixty bacterial strains isolated from kefir grains compared to Escherichia coli O157:H7, Salmonella enterica subsp. enterica serotypes Typhimurium and Enteritidis, Staphylococcus aureus, and Listeria monocytogenes through antagonism test. We tested the antimicrobial activity of lactic acid bacteria supernatants that were active in the antagonism test. The experiment was repeated using supernatants with neutralized pH. Salmonella Typhimurium and Enteritidis survived for 24 hours in kefir fermentation. E. coli O157:H7, S. aureus and L. monocytogenes were recovered up to 72 hours after the start of fermentation. All isolates showed antimicrobial activity against at least one of the pathogens used in the test of antagonism. Supernatants of 25 isolates showed inhibitory activity, and three maintained this activity with neutralized pH. Pathogenic bacteria studied survived for longer than the time normally used for fermentation of artisanal kefir, characterizing a potential danger to the consumer when the raw material does not provide health security. Lactobacillus isolated from kefir grains exhibit antimicrobial activity against strains of E. coli O157:H7, Salmonella serotypes Typhimurium and Enteritidis S. aureus, and L. monocytogenes in addition to that exerted by the lower pH values.

title: EFFECT OF TYPE OF MILKING AND ENVIRONMENT ON THE RAW MILK QUALITY BASED ON SOMATIC CELLS COUNT

description: Abstract: The objective of this study was to evaluate the effect of the type of milking and the environment on raw milk quality by identification of Somatic Cells Count - CCS in the samples obtained from farms in the mesoregion of south goiano and correlate it with the different types of milk, milk components, and time of year. The research was developed in 229 farms associated with the Catalão Cooperative, divided for types of milking: manual and mechanical. A monthly sample was collected in each property in the expansion tank, totaling 8244 samples. Mechanical milking presented the highest number of samples with CCS &gt; 500.000 cells / mL. There was a positive correlation between CCS and fat and total solids - TS, but there was a negative correlation between CCS and protein and lactose. During the rainy season CCS increased compared to dry season. Also, the rise of temperature and humidity index - THI caused a reduction in fat and TS. In conclusion, hand milking was more feasible to obtain the milk CCS parameters required by the legislation and CCS and milk components suffer interference from the time of the year.

title: PHYSICOCHEMICAL PARAMETERS AND SENSORY ACCEPTANCE OF CHOPPED HAM WITH PEA FIBER AIMING AT COST REDUCTION

description: Abstract This study was developed to evaluate the physicochemical and sensorial characteristics of chopped ham prepared with the addition of pea fiber as a partial substitute of meat. Two treatment samples were processed: Control (C)-commercial production; and Fiber Less Meat (FLM)-reduction of 5% of meat and addition of 1% of fiber and 4% of water. After processing, the products were characterized regarding pH levels, texture, objective color, loss by dripping, centesimal composition, scanning electron microscopy (SEM), and sensorial evaluation (9-point hedonic scale acceptability test). Analyzing the texture, the parameters for firmness and chewy were higher (p&lt;0.05) for the C sample. The sample FLM presented higher L* value (p&lt;0.05) and lower a* and b* values (p&lt;0.05) than sample C. Regarding the sensorial evaluation, the items aroma, appearance, texture, and flavor did not present differences (p&gt;0.05). Regarding general acceptability, the samples differed (p&lt;0.05) and the FLM sample presented higher acceptability compared to the control sample. In conclusion, it is possible to use pea fibers in chopped ham as a partial substitute for meat having a final product with high sensorial acceptability and cost reduction.
