Levels of glucose and triglycerides in seminal plasma and spermatic motility in guinea pig fed with 10% more in digestible energy

The objective the study was to determine the levels of glucose and triglycerides in seminal plasma of 10 guinea pigs, which were fed for a period of 2 months with a diet containing 10% more ED. The level of glucose found in seminal plasma was 11.59 ± 0.5 mg/dL and triglyceride value was 55.95 ± 3.2 mg/dL, while the motility was 97% on average. We conclude that in guinea pigs the levels both glucose and triglycerides were increased by major level of ED in feed, but the spermatic motility was not.

Bolsa Familia Program and school enrolment: An analysis of the 2010 Brazilian demographic census

The Bolsa Família Program goal is to promote social development and poverty reduction, through the direct transfer of conditional cash, in association with other social programs. This study aims to analyze whether Bolsa Família had an association with children’s school attendance, which is one of the educational conditions of the program. Our main hypothesis is that children living in households receiving Bolsa Família had greater chances of attending school. Data from the Ministry of Social Development and Combating Famine indicated that children living in households with Bolsa Família had greater school enrolment levels. By using data from the 2010 Demographic Census, collected by the Brazilian Institute of Geography and Statistics (IBGE), some descriptive analyzes and binary logistic regression models were performed for different thresholds of household per capita income. These estimates were made by comparing children who lived in households receiving Bolsa Família to those children not receiving the program. We took into consideration characteristics about the household, mothers, and children. The results were clustered by the municipality of residence of the child. In all income thresholds, children benefi ting from Bolsa Família were more likely to be enrolled in school, compared to children not receiving the benefi t.

Primitivismo y Feminismo en el arte contemporáneo

Para la mentalidad colonialista del siglo XIX la raza negra estaba provista de una extraordinaria sexualidad y lujuria. En la metrópolis el equivalente era la mujer sexuada, la prostituta. En los primeros años del siglo XX este tándem, prostituta-colonizado, sirve a los artistas vanguardistas como elemento de confrontación con la moral imperante. Son las artistas mujeres, con una intención feminista, quienes principalmente utilizan el primitivismo asociado a la mujer en su crítica a los estereotipos. Figura pionera en ello es Hannah Höch, especialmente en su serie De un Museo Etnográfico, en el que asocia figuras femeninas y objetos de arte primitivo. En los años 70 del siglo XX, algunas artistas de la performance, como Carolee Schneemann o Ana Mendieta reivindican el cuerpo femenino con el significado de Origen y Fertilidad que tiene en las culturas primitivas. En este mismo contexto puede inscribirse la escultura Maman de Louise Bourgeois. El elemento de crítica social, que está vigente aún en nuestros días, puede verse en las obras de las Guerrilla Girls.
