A metáfora fundamental do discurso de John Dewey

This work aims to identify the rootmetaphor of John Dewey’s philosophical and educational discourse, by means of rhetorical analyses parameters. This methodology is founded in Aristotle and in the works of Chaïm Perelman and other contemporary authors involved in the revision of Aristotelian philosophy. The article examines the essays “The philosophical work of Herbert Spencer” and “The influence of darwinism on philosophy”, published by John Dewey respectively in 1904 e 1909. They were written in the early years of Dewey in Columbia University, which intellectual environment was not dominated by Pragmatism, and for this reason they can be considered seminal in the structuring of the author’s arguments. The analysis reveals that Dewey is favorable to Darwinian evolutionism thesis and opposite to Spencer’s one. This positioning suggests that Dewey’s discourse is bound to the metaphor “undetermined route” because it situates evolution as a process devoid of previously listed purposes at a pre-determined plan, subject only to the relations that are established, so unpredictable, between organisms and the environmental conditions that surround. Analyzing Dewey’s ideas about education, the article concludes that “undetermined route” is the rootmetaphor of Dewey’s discourse, hypothesis that can contribute to discuss Dewey in the context of contemporary philosophy.

Por uma educação dos sentidos: as realizações artísticas do diretor Luiz Fernando Carvalho

Director Luiz Fernando Carvalho’s artistic performances, specially the miniseries Hoje é dia de Maria (2005), A Pedra do Reino (2007) and Capitu (2008), target a true setting of commitment, preoccupation and conciliation towards its spectator’s education. And the purpose of this text is to talk about such reeducation of senses explored by Carvalho’s artistic performances.

Replantation as treatment for extrusive luxation

In the treatment of extrusive luxation cases, it is important that the repositioning of extruded tooth in the socket is done as soon as possible. If this does not occur, periapical clot becomes organized and makes replantation difficult reposition. In this article the patient referred to the Clinics for dental trauma sustaining extrusive luxation of the maxillary right central incisor. The patient reported having suffered a bicycle accident 12 days before, which caused traumatic tooth injuries. The repositioning was attempted without success and an alternative form of treatment was necessary to solve the case. Intentional tooth replantation, which is the deliberate extraction of the tooth and its replantation, was indicated. This technique allows clot removal and correct repositioning of the extruded tooth. Care should be taken as endodontic treatment is required for the prevention of subsequent infection-related resorption. Intracanal dressing with calcium hydroxide was used for 30 days before final root filling. Splint, systemic antibiotics and avoidance of further damage to the root surface is also important. After 49 months, showed clinical and radiographic characteristics of normality and demonstrates the availability of this technique to adversity in trauma.

Control Methods and Evaluation of Bacterial Growth on Fresh and Cooled Stallion Semen

The penis and prepuce of the stallion have a high bacterial load on its surface, forming a natural microbial flora that contaminates the semen during ejaculation. Bacterial growth in semen may cause a decline on sperm quality, viability, and fertility and predisposes the occurrence of endometritis in inseminated mares. Thus, the aim of this study was to evaluate the effect of penile wash before semen collection, the addition of different commercial skim milk-based extenders containing antibiotics (BotuSemen and INRA96), and the removal of seminal plasma by filtration on the quality, viability, and bacterial proliferation on fresh and cooled stallion semen. Animals that were never submitted to penile wash before semen collection tended to have lower bacterial contamination in the ejaculate. Semen samples extended in BotuSemen showed superiority in total motility, progressive motility, average path velocity, and rapid sperm and lower bacterial contamination in relation to semen samples extended in INRA96 after 24 hours of cooling. No difference was found in these parameters between the storage temperatures (5 degrees C and 15 degrees C). Furthermore, the removal of seminal plasma by filtration reduced the bacterial load in semen after cooling. In conclusion, the penile wash before semen collection tended to reduce the bacterial growth in fresh semen. The use of a semen extender with appropriate antibiotics and removal of seminal plasma by filtration were effective in reducing the bacterial contamination and preserved the quality of cooled stallion semen.

Spermatic and testicular damages in rats exposed to ethanol: Influence of lipid peroxidation but not testosterone

Chronic consumption of ethanol causes morphological and physiological changes in the reproductive system of mammals. Vitamin C has an antioxidant role in organisms by neutralizing the ROS (reactive oxygen species) produced by oxidizing agents and this vitamin has an important function in the male reproductive system. The aim of this study was to evaluate whether vitamin C could prevent or attenuate the alterations in the male reproductive system caused by ethanol consumption. To test this hypothesis, male rats were divided into three experimental groups and treated by gavage for 63 days. The ethanol (E) and ethanol +vitamin C (EC) groups received 2 g/kg of ethanol (25% v/v) daily. In addition to ethanol, the EC group received vitamin C at a dose of 100 mg/day, diluted in water. The control group (C) received only the vehicle. On the 64th experimental day, the animals were anesthetized and euthanized, and blood was collected for plasmatic hormonal analysis. The testis, epididymis, vas deferens, and seminal vesicles were removed and weighed. Sperm from the vas deferens was submitted to morphological and motility analysis. The testis and epididymis were used for oxidative stress and histopathological analysis, sperm count, morphometric analysis of the testis, and stereological analysis of the epididymis. The results showed that vitamin C has a protective effect in the testes of adult male rats, entirely normalizing the parameters of sperm count, spermatogenesis kinetics, lipid peroxidation levels, and sperm motility, as well as partially normalizing the histopathological damage in the testis, epididymis, and sperm morphology. Thus, we concluded that lipid peroxidation is a major mechanism by which ethanol affects the testes and sperm, whereas no plasmatic testosterone alterations were found.
