Tercera edad empoderada y cultura urbana expulsiva en Latino America
No full textIn this paper are presented one reflection about how some authors study the social tissue and the urban culture, and how this last one is articulated with the themes of inclusion or exclusion in the latin american ageing. It also takes into account social situations that allow further assume the existence of integration processes with other expulsive. Both of them, with a high level of complexity and heterogeneity, especially since the Latin-American reality. One group especially vulnerable to policies of expulsion is of aging, who are in a swing between a situation of vulnerable not-citizenship and a renewal of their agenda of citizen and participatory rights
Surgical anatomy for the treatment of ocular cancer by Antonio Scarpa (1752-1832)
Get PDFAntonio Scarpa (1752-1832) (Fig.1) was one of the most famous anatomists during the second half of 18th and the early 19th century, being a professor of anatomy at the Universities of Modena and Pavia. He is considered as the “Father of Italian ophthalmology”, because he wrote the first study for ocular diseases in Italian. His studies on ocular cancer did not offer only a detailed analysis of the disease but also a description of a unique surgical technique for its treatment based on the surgical and clinical anatomy of this disease
Comparative morphology of the visual and auditory reflex centres in the African grasscutter (Thryonomys swinderianus – Temminck, 1827)
Get PDFThe African grasscutter is a nocturnal rodent, currently bred as a minilivestock, and research model. The present study was aimed at describing the structure of the auditory and visual reflex centres, with a view to understanding the nocturnal behaviour of the rodent. The rostral and caudal colliculi of the mesencephalic tectum were harvested from neonate, juvenile and adult African grasscutters and subjected to basic neuro-anatomical techniques. On each postnatal period, the corpora quadrigemina was bound rostrally by the 3rd ventricle and caudally by the 4th ventricle, and the caudal colliculus was grossly bigger than the rostral colliculus. The heights of the rostral and caudal colliculi in the neonates were 6.38 ± 0.28 mm and 8.78 ± 0.08 mm, respectively, and the difference was significant (P < 0.05). The values in the juveniles were 5.94 ± 0.21 mm and 11.45 ± 0.17 mm, respectively, and the difference was significant (P < 0.05). The values in the adults were 8.08 ± 0.35 mm and 16.16 ± 0.30 mm, respectively, and the difference was also significant (P < 0.05). The relative weight of rostral colliculus in the adult was significantly (P < 0.05) higher than that of the neonates, but not the juveniles. The relative weight of the caudal colliculus in the adults was significantly (P < 0.05) higher than that of the juveniles. In conclusion, the relatively bigger caudal colliculi, than the rostral colliculi, observed at all postnatal periods studied, suggests a more acute auditory than visual ability in the African grasscutter
