Hematological and biochemical changes in a Phrynops geoffroanus (Schweigger, 1812) population in response to environmental stressors

Turtles are among the most endangered vertebrate groups, and the main threats to populations are environmental pollution and habitat degradation. The species Phrynops geoffroanus, popularly known as “Geoffroy’s side-necked turtle”, has proliferated in polluted environments, where adverse conditions could influence their living habits and physiological condition. Studies that monitor the effects of environmental pollution are key to understanding the species’ biology and designing effective conservation strategies. Thus, the analysis of hematological and biochemical parameters has been shown to be important in assessing the health of wild animals and risks for the animal and ecosystem. This study aimed to assess the environmental influence on the physiology of a P. geoffroanus population through the evaluation of antioxidant status and responses to environmental stressors, compared to specimens from a place under controlled conditions. Blood samples of 60 specimens were collected, 30 from the Felicidade Stream, polluted environment, within the city of São José do Rio Preto, and 30 from the “Reginaldo Uvo Leone” breeding farm, Tabapuã, SP, a place under controlled conditions, whose samples constituted the control group. They were evaluated by hemogram and by determining thiobarbituric acid reactive species (TBARS), Trolox-equivalent antioxidant capacity (TEAC) and the activities of the antioxidant enzymes catalase and glucose-6-phosphate dehydrogenase (G6PDH). There was a wide variation in hematological parameters of P. geoffroanus from the urban environment. The red blood cell count and hemoglobin values were significantly less than those observed in animals from the breeding farm (P = 0.0004; P = 0.0371, respectively). There was a significant increase in the number of thrombocytes (P < 0.0001) and leukocytes (P < 0.0001) in the animals from Felicidade Stream. The stress indices were similar between the two groups (P = 0.4077). TBARS levels showed the cytotoxic potential of compounds in the urban environment, whose animals had elevated levels of lipid peroxidation (P < 0.0001), despite showing a response to environmental damages with increase in antioxidant capacity, as demonstrated by the TEAC assay (P = 0.0207). The lower catalase enzyme activity noted in individuals from the urban environment (P = 0.000184) could be due to the presence of inhibitory compounds. On the other hand, G6PDH activity was higher (P = 0.002962), where this enzyme acts in the generation of NADPH, which is used in several detoxification pathways. We conclude that environmental contamination can increase oxidative damages and generate physiological changes in this species. These data are very useful for the conservation of P. geoffroanus and turtles in general, and confirm that these techniques are effective in monitoring natural regions and that P. geoffroanus can serve as an environmental contamination bioindicator.

Do nobre ao patético: o herói de Victor Hugo e o anti-herói de Machado de Assis

This article analyses how Victor Hugo embodied his heroes and Machado de Assis his anti-heroes. Three Assis´s short stories and three Hugo´s novels are compared: “O caso da Vara” and the chapter “L‟affaire Champmathieu” from the book Les Misérables; “Noite de Almirante” and Les Travailleurs de la Mer; “Um incêndio” and Quatre-Vingt-Treize. These texts present similar situations, but each author shows an outcome that reveals their literary proposal. For this reason, Comparative Literature and Intertext had been used as base of reflection for this article.

Victor Hugo: sobretudo, poeta

Victor Hugo was one of the most important writers of the French litterature. He publishied novels and plays, but he dedicated himself especially to the poetry. This article aims to describe the poetic journey of Victor Hugo and analyses how the History of France, the life of the writer and the discussions about Romantism combined and formed a work that traverses the century.

A recepção crítica das peças de Victor Hugo na França e no Brasil

Les premières pièces de Victor Hugo ont été les responsables d'une véritable révolution dans l'histoire de las Litterature Française, mais elles n'ont pas eu une acceptation immédiate de la part de la critique, qui s'est partagée entre les partidaires des romantiques et, par conséquent, de nouvelles idées diffusées par le Cénacle et les classiques, les adversaires des jeunes écrivains qui ont embrassé les concepts hugoliens, Au Brésil, la réacrion a été postérieure, mais identique. Qualqu'on ne trouve pas dans les journaux des discussions à propos de la nouvelle école, des nouvelles idées ont été, au début, rejetées par les intellectuels brésiliens et, quelque temps plus tard, adoptées par les écrivains désirant créer un théâtre national basé sur les prinipes défendus par Victor Hugo, le porte-parole du mouvement romantique.
