Morphological aspects of spermatogenic cells at different stages of sexual maturation in black isogenic C57BL/6/Uni mice

In order to study the morphological changes that occur in cells of the testes of isogenic black mouse C57BL/6/Uni into three periods during spermatogenetic used 15 mice divided into 3 groups of 5 animals with 40,50 and 60 days of age. The mice were sacrificed and weighed. Testicles were weighed and measured, and histologically processed and stained with HE, PAS and Masson Massom-H and evaluated under light microscopy. It was observed that group I with 40 days of age in the seminifcrous tubules had a lumen with sparse small amount of interstitial tubular cells. In the seminiferous epithelium type A spermatogonia, intermediate and B were identified, which occupied the compartment adbasal and intermingled with these cells in spermatocytes I in Pachytene and leptotene was observed, whereas in the adluminal compartment Golgi phase spermatids we observed the presence of acrosomal granule. In group II, the cells of the seminiferous epithelium were developed and it was observed in round spermatids cephalic hood phase plus many elongated spermatids in acrosome phase and Sertoli cells. In Group III, 60 days old, it was found that seminiferous epithelium which was of the tubules had elongated spermatids in acrosome phase and maturation, with elongated nuclei and acrosomal system typical of spermiation in the presence of sperm and residual bodies near the tubular lumen. Therefore morphological evolution of germ cell testicular spermatids can be checked and recognized in its four phases: Golgi, cap, acrosome and maturation over the age of the animal.

Os sentidos da cirurgia estética: utilidade, futilidade, agência e/ou incorporação

This article aims to reflect on the growth of the practice of plastic surgery for cosmetic purposes and its relationship with the contemporary consumer culture. In other words, we discuss how this practice expresses the values and principles for consumer culture and configures itself differently in different contextsin, as the cities of Sao Paulo and London, where he held field work involving the collection of information in press materials, data files, interviews and observation in clinical aes‐ thetic.

Projetos de lei sobre medicalização da educação: biopolítica, controle e resistência na contemporaneidade

At present, the processes of medicalization of childhood have reached the school spaces where diagnostic labeling accompanied of prescription of psychotropic drugs proliferate. The present work aims to study through the Foucauldian genealogical approach, the process of medicalization of education, with a special attention to analysis of Brazilian bills which serve to the medicalization logics and to the study of resistance movements which emerged with the purpose of denouncing psychopathology-causing strategies. It is considered that the school spaces, subject to the disciplining processes and standardization of bodies, have gained through bills, new devices of support to the psychiatric discourses. These, by appropriating of the childhood considered problem, have spawned diagnoses and psychopharmacological drugs, process that has been faced by resistance movements identified with proposals for enhancement of the plurality of life.

Os limites do corpo: modificações corporais

El cuerpo presenta rastros de la historia y cultura de las sociedades por toda la historia de la humanidad. El presente estudio quiere, através de pesquisas sobre el cuerpo, entender como las modificaiones corporales han acompañado la historia del hombre, de las tribus antiguas hasta la atualidad y como son hoy los procedimientos de cambiar la forma física. Através de trabajo de campo conocer profisionales que hacen algunos tipos de modificaciones corporales y gente que las tienen en sus cuerpos, entender las razones para que cambien sus cuerpos permanentemente - en la mayoria de los casos - y como la idea de individualidad surge cuando se hace una marca personal en el cuerpo. Además, compreender el porque esas prácticas se están convirtiendo cada vez mas común en nuestra sociedade actual

Avaliação das áreas de conflito de uso em APP da microbacia do alto água fria, Bofete (SP)

The misuse of land by man and is causing serious problems to the environment, resulting in ecological imbalance and depletion of natural resources, especially when it comes to areas of permanent preservation, that ecosystems are essential for balance and water conservation importance . Conflicts of land use is a major cause of silting of rivers and water bodies, causing significant losses in soil and decaying natural water resources both in quantity and in quality. Within this scenario, the planning becomes essential for the control of environmental impacts to the environment factor. This study aimed to evaluate land use conflicts in permanent preservation areas of the stream Água Fria watershed, Bofete (SP) using Geographic Information System and satellite image of LANDSAT - 5 of 2010, scale 1:50000. The results show that 51.16% of the permanent preservation areas of the watershed are conflicting, especially for pasture (88.94%) and reforestation with eucalyptus (11.06%). The GIS IDRISI Selva and Cartalinx along with GIS techniques demonstrated speed and efficiency in identifying, measuring and editing maps of land use, preservation and ongoing conflicts in areas of permanent preservation.
