Uso de variáveis relacionadas com a produção embrionária, em camundongos, como fatores preditivos

Mouse embryo production by superstimulation is a multifactorial process. To minimize the number of sacrificed animals and to maximize the results of the superstimulatory treatment, it should be possible to predict the risk of do not get embryos from such a treated animal. This work aimed to evaluate if the variables - hormone concentration and the timing of its administration, the copulatory plug presence and individual male used to mating – could be predictive factors on the mouse embryo production. Females were distributed in four groups (cross-over design) related to scheduled superstimulation treatment (1300h or 1700h) and eCG/hCG administered concentration (5 or 10IU). After the hCG treatment, females were put to mate. On the next morning it was verified the presence of a copulatory plug (D0.5). Embryo recovery was performed from D2.5 to D4.5 by flushing the oviducts and uterine horns. Total structures recovered (TSR) and the viable embryos (VE) were classified by its morphology. Viability rate (VR) was calculated with VE in relation to TSR (x100). Group comparison was analyzed with 5% of significance. There were no significant differences among groups, even when only main effects were analyzed (hormone concentration and timing of its administration). There was significant difference in VR from animals with or without plug and from the worst and best males used. It was concluded that neither the hormone concentration nor timing of its administration - or their association – was significant as predictive factors for the embryo production. However, the plug presence was related to higher VR.

Variação sazonal das variáveis físicas e químicas em riachos de duas bacias da região centro-sul do estado do Paraná, sul do Brasil

The present study was developed in two streams from the two different drainage basins located in the mid-southern region of Paraná state. In each stream were evaluated some physical and chemical parameters in open (without streamside vegetation) and shaded (with streamside vegetation) segments. Monthly samplings were carried out from January to December 2007. The following limnological parameters were measured: water temperature, specific conductance, oxygen saturation, pH, turbidity and current velocity. In the same stream were not observed differences among segments from the drainage basins, and nominal values and seasonal pattern have been very similar between open and shaded ambient. A Principal Component Analysis (PCA) showed small divergence between streams and segments, with separation of groups with base sampling dates. The results suggest that the region is homogeneous according to physical and chemical water conditions, therefore, stronger influenced for time factor, and diverging seasonal periods associated a climatic region condition.

The objective of this research study was quantify the power, force of vertical impulse, jumping height and the relation of the power output during the execution of the layup in basketball, by variables associated to anthropometric data. The study was carried with seven basketball players, university students, male, from the Universidade Estadual Paulista Julio Mesquita Filho (Unesp) basketball team, from Bauru City. The players were an age of 20,7 ± 2,4 years old, body weight of 77,1 ± 9,4 kg, body fat of 14,7 ± 3,6%, lean mass of 65,5 ± 6,2 kg and height of 180,0 ± 5,0 cm. Each player did the ability of the layup three times, with a previous time to adapt. The kinetic and kinematic values was obtained from the data of a system that consists of photocells and a contact carpet from a system called JumpSystemâ (CEFISE), using after that equations of UVRM and impulse. The photocells was dispose to capture the previous run-up, as well the speedy in the time of two steps of the layup, and it was also synchronized with the contact carpet in the last step, to preserve the exactly time of the propulsion of jump. In this way, the values and the kinetic variables found was vV (2,94 ± 0,3 m's-1), vH (11,3 ± 3,4 m's-1), vI (11,8 ± 3,2 m's-1), time of contact (0,214 ± 0,2 s), angle of jump (15,9 ± 6,26 graus) and H (44,3 ± 8,9 cm). The variables and the kinematic values found was FimpV (974,9 ± 119,03 N, PP (3112,9 ± 633,9 W) and PM (1556,4 ± 316,9 W). To better understand the ability of layup in basketball, as the kinetic variables, kinematic variables and anthropometrics that determine the performance, the study did correlations between dV (H) with vV, vH, vI, angle, FimpV, PP e PM; FimpV, PP e PM com with the kinetic variables of vV, vH, vI, angle, and anthropometric variables of PC and height, and correlations of PP e PM with %G and MM. So, significant results was found between the correlations of dV with FimpV (R2 = 0,81)...

Perfil hematológico de cabras Saanen e mestiças (1/2 Saanen e 1/2 Anglo-nubiana) criadas em clima tropical do Ceará

The aim of this study was to determine the influence of climatic conditions on the hematological profile of Saanen and mixed-breed (1/2 Saanen x 1/2 Anglo-Nubian) goats, as well as to define reference values for these animals bred in Ceara, Brazil. Thirty goats were utilized and blood samples were collected monthly during the rainy (February to May) and dry (August to November) periods to obtain an erythrogram a leukogram. The averange were compared by the t-Student test and Mann Whitney test, with parametric and non-parametric distribution of the data, respectively, where p<0.05 was considered significant. A study was carried out of simple Pearson correlations of the hematological parameters with environmental and physiological variables. The number of red blood cells (RBCs) was higher in the Saanen goats and in the rainy period, while the hematocrit was higher in the dry period (p<0.05). The leukocytes and lymphocytes were higher in the 1/2S1/2 AN goats in the two periods (p<0.05). In the two genotypes, the leukocytes and lymphocytes were higher in the dry season and the segmented neutrophils higher in the rainy season (p<0.05). The other parameters did not differ (p>0.05). The RBCs and segmented neutrophils displayed a negative correlation with air temperature, but positive with relative humidity and rectal temperature (p<0.05). The hematocrit positively correlated with air temperature and respiratory rate (p<0.05). The leukocytes and lymphocytes showed a negative correlation with rectal temperature (p<0.05). It was therefore concluded that Saanen females are more affected by climatic variations and that the rainy season has a greater negative impact on hematological parameters. The values obtained could serve as a reference for these genotypes in Ceara.

Variáveis de impacto na queda da mortalidade infantil no Estado de São Paulo, Brasil, no período de 1998 a 2008

This is an ecological, analytical and retrospective study comprising the 645 municipalities in the State of Sao Paulo, the scope of which was to determine the relationship between socioeconomic, demographic variables and the model of care in relation to infant mortality rates in the period from 1998 to 2008. The ratio of average annual change for each indicator per stratum coverage was calculated. Infant mortality was analyzed according to the model for repeated measures over time, adjusted for the following correction variables: the city's population, proportion of Family Health Programs (PSFs) deployed, proportion of Growth Acceleration Programs (PACs) deployed, per capita GDP and SPSRI (Sao Paulo social responsibility index). The analysis was performed by generalized linear models, considering the gamma distribution. Multiple comparisons were performed with the likelihood ratio with chi-square approximate distribution, considering a significance level of 5%. There was a decrease in infant mortality over the years (p < 0.05), with no significant difference from 2004 to 2008 (p > 0.05). The proportion of PSFs deployed (p < 0.0001) and per capita GDP (p < 0.0001) were significant in the model. The decline of infant mortality in this period was influenced by the growth of per capita GDP and PSFs.

Desidratação e balanço hídrico de um anfíbio anuro (Rhinella schneideri)

A manutenção do balanço hídrico ou de água é particularmente desafiadora para os anfíbios em virtude de seu tegumento altamente permeável e o risco associado de perda evaporativa de água. Neste sentido, anuros terrestres exibem uma grande diversidade de mecanismos que atuam na diminuição da perda evaporativa de água e contribuem para a manutenção de um balanço hídrico adequado. Ademais, algumas espécies de anuros são conhecidas por tolerar altos níveis de desidratação e por engajar-se em atividades de rotina na natureza, ainda que sob níveis variáveis de desidratação. Finalmente, o próprio nível de desidratação pode acarretar alterações nos fatores envolvidos na manutenção do balanço de água dos anuros, aspecto muito pouco explorado em espécies terrestres neotropicais. Dessa forma, no presente estudo, mensuramos as taxas de perda evaporativa de água (PEA), reidratação a partir de água livre (Re) e calculamos a resistência da pele a desidratação (RP) em indivíduos adultos de Rhinella schneideri submetidos experimentalmente a diferentes níveis de desidratação (99%, 90%, 80% e 70% da massa corpórea inicial). Ademais, medimos as alterações causadas pela desidratação na osmolalidade plasmática (Osm), hematócrito (Htc), concentração de hemoglobina no sangue ([Hb]) e massa percentual dos órgãos viscerais. O objetivo central deste estudo foi avaliar os efeitos potenciais de diferentes níveis de desidratação sobre indicadores e repostas fisiológicas relevantes para a manutenção do balanço hídrico em uma espécie de anfíbio anuro terrestre. Nossos resultados mostram que quanto mais desidratados os animais, maiores a RP, a Re, a Osm, o Htc e a [Hb], e menores a PEA, e a massa percentual do fígado e do rim. O aumento da Osm, Htc e [Hb] indicam uma diminuição do compartimento aquoso do sangue, o que pode estar relacionado ao aumento da Re. A relação entre diminuição da PEA e aumento da...

Ocorrência de reabsorção radicular no tratamento ortodôntico: revisão crítica da literatura

The root resorption is one of the possible sequels of greater complexity to the orthodontist, the difficulty of detection and be asymptomatic. The presence, during the orthodontic treatment, is linked to a multifactorial origin, a complex combination of biological activities, anatomical, physiological, genetic variables and mechanical forces. Thus, the aim of this study was perform to critical literature review related to root resorption in orthodontic movement. Were included articles published between 2004 to 2014, indexed in the PUBMED database. Used descriptors contained in the Mesh, being adopted as inclusion criteria: clinical trials in humans, only articles that had clear ideas and objective, articles with English language. The search strategy used resulted in 24 articles and after applied the inclusion and exclusion criteria, 11 articles remained. Based on the results of this study it was concluded that heavy forces of intrusion, inclination and torque leads to a greater degree of root resorption; its etiology is multifactorial, the periodic radiographic control during treatment is needed and further studies are suggested to identify more specifically the causes and risk factors for root resorption.
