title: Polyurethane derived from Ricinus Communis as graft for bone defect treatments

description: Abstract This work evaluated polyurethane (Polyquil®) as a graft for treatment of bone defects. Bone defects of 1.5 × 0.5 cm were made in the calvaria of 16 rabbits. Eight animals had their defects treated with Polyurethane (Treated) and 8 of them had their defects filled with blood clot (Control). In the second experiment, segmental defects of 0.5 cm were performed at the zygomatic arch of 16 rabbits. Eight animals were treated by guided bone regeneration, using a latex membrane, associated to grafting of polyurethane while the others were not treated (Control). The bone tissue morphometry in the craniotomy experiment resulted in a higher bone volume in the Treated group at 60 days (p &lt;0.05, t student test). Microscopic and radiographic images demonstrate the formation of a bone bridge in the segmental defect, 60 and 120 days after surgery in the Treated group, different from the Control group with incomplete healing.

title: Ovine epididymal spermatozoa preservation in liquid state with or without seminal plasma epididimários ovinos

description: ABSTRACT: Preservation and use of spermatozoa that have been recovered after death can extend the use of genetically superior animals. The objective of this study was to evaluate the maximum period for which ovine spermatozoa could be successfully stored in refrigerated dilution medium post-mortem, with or without added seminal plasma. Three samples of spermatozoa collected in an artificial vagina from 10 rams, or from the tails of four epididymes from the same rams at the time of death (G0) and six (G6), twelve (G12), twenty-four (G24) and forty-eight (G48) hours after death were used. After recovery, the spermatozoa were refrigerated at 5°C in either control medium (CM) or control medium plus 20%homologous seminal plasma (SP) and evaluated for 72 hours from the start of refrigeration. The G48 samples had a lower(P &lt;0.05) total motility (TM) and plasma membrane integrity in the hyposmotic test (HOST) than the other groups evaluated at all analyzed times. The TM decreased (P &lt;0.05) after 24 hours of cooling in semen collected in AV, at G0 and G24 and after 48 hours of refrigeration in G6 and G12. The TM and HOST integrity and sperm morphology did not differ between samples refrigerated in CM or SP. In conclusion, it is possible to collect epididymal spermatozoa up to 24 hours after death. Sperm viability can be prolonged fora further 48 hours by refrigeration. However, total motility decreases from 24 hours after refrigeration and the supplementation of 20% seminal plasma to the extender has no effect on spermatozoa longevity.

title: Students’ knowledge of metabolic syndrome after educational intervention

description: ABSTRACT Objective: To analyze the knowledge of children and adolescents about risk factors for metabolic syndrome (MS) before and after educational interventions. Method: A quasi-experimental, comparative, prospective and intervention study conducted in 2015 and 2016 with 43 students in the city of Picos (state of Piauí-PI). Five health education meetings were held. For the knowledge analysis, was applied a questionnaire at three different moments. Results: Participants’ mean age was 12.6 years (± 2.1), of which 60.5% were female. The ‘More than good’ level of knowledge went from 20.9% to 55.8% after interventions. When evaluated late, students maintained a higher level of knowledge compared to before the interventions. Most said they were able to change their lifestyle after educational meetings. Conclusion: The educational intervention promoted increase of knowledge and stimulated changes in attitudes related to risk factors associated with MS.

title: Direct, indirect and simultaneous selection as strategies for alfalfa breeding on forage yield and nutritive value

description: ABSTRACT Alfalfa breeding aimed at trait improvement for livestock feed takes longer periods of time, if compared to many other crops. Therefore, better selection methods are necessary for the success of alfalfa breeding programs. Although knowing about selection methods is quite important, there is a notable lack of information, as regards successful solutions. This study aimed to use direct, indirect and simultaneous selection methods for selecting alfalfa cultivars, based on yield traits and nutritive value. The evaluated traits were subdivided into two groups: forage yield and nutritive value. Selection gains were estimated by direct, indirect and simultaneous selection for each group, considering the selection of the 25 % best cultivars. Direct and indirect selections among genotype averages are not efficient to provide the desirable responses to the whole set of traits. The results for simultaneous selection, using the Tai index, provided a more balanced gain distribution to the set of traits in all cuts. The simultaneous selection allowed the identification of the 5681 and Verdor cultivars in the first cut, as well as ProINTA Patricia in the second cut, as superior in the two groups of evaluated traits.

title: Agronomic characterization and heterosis in watermelon genotypes

description: ABSTRACT In order to increase the yield of vegetables of agronomic interest, heterosis has been studied in view of the superiority of hybrids, if compared to genotypes obtained by free pollination. This study aimed to estimate the relative heterosis in watermelon hybrids, regarding the most important agronomic traits, in order to develop future cultivars. The genotypes 'JNY', 'ORA', 'KOD', 'SOL', 'CHG', 'PEA' and all hybrids among them were used, totaling 36 treatments. A randomized block design, with three replications and five-plant plots, was used. The genotypes 'ORA', 'SOL', 'CHG' and 'PEA' were promising for the development of watermelon hybrids with higher weight, whereas 'JNY' and 'KOD' provided combinations with lower fruit weight and smaller seeds, indicating their potential for the development of cultivars of the 'ice box' type. The hybrids 'CHG x ORA' and 'ORA x CHG' were promising to meet the market demand for larger fruits, while 'KOD x JNY' and 'JNY x KOD' could be targeted to the market of smaller fruits.

title: Maternal smoking during pregnancy and birth defects in children: a systematic review with meta-analysis

description: This systematic review aimed to investigate the association between maternal smoking during pregnancy and birth defects in children. We performed an electronic search of observational studies in the databases ovid MEDLINE (1950 to April 2010), LILACS and SciELO. We included 188 studies with a total of 13,564,914 participants (192,655 cases). Significant positive associations were found between maternal smoking and birth defects in the following body systems: cardiovascular (OR: 1.11; 95%CI: 1.03-1.19), digestive (OR: 1.18; 95%CI: 1.07-1.30), musculoskeletal (OR: 1.27; 95%CI: 1.16-1.39) and face and neck (OR: 1.28; 95%CI: 1.19-1.37). The strength of association between maternal smoking and birth defects measured by the OR (95%CI) is significantly related to the amount of cigarettes smoked daily (χ2 = 12.1; df = 2; p = 0.002). In conclusion, maternal smoking during pregnancy is associated with congenital malformations in children and this association is dose-dependent.

title: Stormwater source control with infiltration wells under a new conception

description: ABSTRACT The objective of this study was to evaluate a new concept of infiltration well as in loco stormwater drainage source control. This infiltration well, namely P-GHidro, has holes in the wall of the concrete rings, layer of gravel external to the rings in order to improve the water distribution, a geotextile prefilter on the cover, and additional filters on the bottom and on the sides between the gravel and the soil. An infiltration well common in San Carlos (P-SC), São Paulo, Brazil, was used as reference, and its construction uses concrete rings juxtaposed to the soil without side holes or prefilter. Six tests of simulated rain were performed for each design infiltration well. The experimental data of infiltrated water flow were modeled by Puls method. The hydraulic conductivity, constant or variable, was used as a model adjustment parameter to the experimental data, and the adjustment was assessed using the coefficients of determination (R2) and Nash-Sutcliffe (NS). P-GHidro had a better performance in the stormwater infiltration, with stored volume and emptying times smaller than the P-SC. The modeling showed good adjustments to the experimental data for constant hydraulic conductivity (average R2 = 0.92 and NS = 0.56) and even better adjustments for variable hydraulic conductivity (average R2 = 0.97 and NS = 0.97).

title: Indicator of environmental health: formula modifications and indicator applications in Brazil

description: ABSTRACT The Environmental Health Indicator (Indicador de Salubridade Ambiental - ISA) was established in 1999 by the São Paulo’s State Council of Sanitation (Conesan). Although this indicator was created to measure the level of environmental health of the municipalities in São Paulo state, Brazil, ISA has been applied in several other regions of Brazil. Moreover, throughout these 17 years, the original ISA formulation has been altered according with local characteristics, as suggested by the manual that originated it. Thus, this study aimed to evaluate ISA application state of the art in Brazil, by the identification of the progress, gaps, and challenges of its use. An extensive literature investigation was performed in order to find studies available in electronic media that used ISA. We identified and analyzed 60 cases. The Northeast and South regions are those with the greatest number of studies, and the majority of them (41.6%) are result of master’s dissertations. Each study uses an average of six first order indicators, and the literature review is the predominant method for choosing and evaluating them. Finally, we showed that the differences between the ISAs are actually a drawback for this indicator use. Since each study has peculiarities in terms of indicators, weights, and criteria calculation, it is only possible to compare the results from the same study over time, but these differences preclude the comparison between the values obtained in different studies.

title: Microbiological evaluation of water fountains of public and private schools from Santa Rita city (PB), Brazil

description: ABSTRACT The quantity and the quality of drinking water intake are directly related to human health. In order to guarantee the safety and potability of drinking water, a series of steps ranging from treatment to distribution must work properly, and if any of them fails, contamination can occur. Based on this assumption, the aim of the present work was to check the microbiological water quality in drinking fountains from pre-school and elementary public and private schools in the city of Santa Rita, Paraíba, Brazil. The analyzes of total coliforms, thermotolerant bacteria and heterotrophic bacteria were carried out according to the standards and methodologies of the American Public Health Association. Based on the standards from Decree 2,914 of December 12, 2011, from the Brazilian Health Ministry, of the total coliforms, 12 samples (100%) were unfit for consumption, and thermotolerant coliforms were detected in 33.33% of the samples. The heterotrophic bacteria count ranged from 1.5x102 to 1.6x103 CFU.mL-1, and as such, all of the samples were unsuitable for human consumption. Thus, we suggest the implementation of a rigorous maintenance process that monitors and controls hygiene and microbiological contamination in the drinking fountains at these locations. Additionally, we recommend the adoption of preventive and corrective measures such as water treatment, regular cleaning and the maintenance of reservoirs, filters and drinking fountains, in order to provide quality water at these schools.

title: Acoustic radiation force impulse elastography of the eyes of brachycephalic dogs

description: ABSTRACT Eyes from brachycephalic dogs were studied by acoustic radiation force impulse (ARFI) elastography to establish quantitative and qualitative reference values related to the shape and rigidity of some ocular structures. Eighty-four eyes from 42 adult brachycephalic dogs were included in this study. Animals were subjected to physical, laboratory, and ophthalmic examinations. Following confirmation of good health, the dogs were subjected to ultrasonography and ARFI elastography, emphasizing the optic nerve, ciliary body, and lens. On qualitative elastography, homogeneous characteristics were observed on the ciliary body and optic nerve. Aqueous and vitreous humors were visualized as mosaic-like images. Quantitative elastography showed the mean optic nerve shear wave velocity (SWV) was 1.01±0.27m/s, temporal ciliary body was 0.91±0.24m/s, and nasal ciliary body was 0.91±0.3m/s. The SWV of the lens values were out of range, this value was not detectable by this software. Elastography has proved to be a non-invasive procedure and feasible in dogs. The establishmentof the parameters of degree of rigidity of ocular structures will serve as a baseline for animals with eye disorders. Results may be extrapolated to primary research on the applicability of ARFI in the evaluation of ocular bulb in humans.
