The independence of adaptations: the metanarrativity and metafictionality of Ian McEwan´s Atonement adapted for the cinema

Conceiving of cinematographic adaptations as being independent of their source material has come to be the standard approach for most specialists in this area. The stress on fidelity has made way for many other approaches, such as those focused on intertextuality, on the dilemma of form v. content, or on questions of genre and gender. The objective of this article is to present an overview of the principal theories which have been developed in the area as from 2000 in order to support this notion of independence, which will be exemplified by an exposition of the strategies used to adapt the metafictional and metanarrative elements in Atonement (2001) for the cinema.

Análise da frequência de micronúcleos frente á utilização de colutório bucal com base alcoólica em indivíduos fumantes e não fumantes

Micronuclei (MN) originate from chromosome fragments or whole chromosomes that lag behind at anaphase during cell division can occur due to excessive exposure to harmful agents, defects in mitosis and / or DNA repair process. The study evaluated the frequency of micronuclei in cytological samples after daily use of alcohol -based mouthwash mouth in smokers and non-smokers. We assessed 30 subjects, aged between 17-42 years and established as exclusion criteria: alcohol consumption; periodontal disease; systemic diseases that may interfere with the integrity of the oral mucosa; individuals with medical or pharmacological history that affect the performance of the study, family history of malignancies. For smokers the inclusion criterion was a minimum consumption of 20 cigarettes / day, and the contrast required for non-smokers. The sample was divided into 02 experimental groups: Group 1 Smokers and Group 2 Non-Smokers, both groups performed mouthwash (alcohol 21,6%) with Listerine® Defense of Teeth and Gums for 04 weeks cytological collection were performed on buccal mucosa and portion median border of the tongue, one for initial, week 0 control, and subsequent three weeks with continued use of mouthwash. The collected material was stained by specific staining Feulgen / Fast Green. The analysis of 3000 cells / individual was performed by light microscopy statistics used Kruskal- Wallis and Mann-Whitney tests for frequency MN. The frequency of micronuclei in buccal mucosa was 1.6 ± 1.75 and 1.46 ± 2.06 for the site language to Group 1 Smokers of showing a slight increase compared with Group 2 Non-smoking, which showed a variation of 1.2 ± 1.53 for the buccal mucosa site and 0.86 ± 1.41 for the site language. However, this difference was not statistically significant. The results suggest that alcohol-based mouthwash tested is not an inducer of genotoxic changes, thus not changing the frequency...

Estudio histológico del processo de reparación alveolar después de la aplicación tópica de la solucioón anestésica prilocaína 3 % con felipressina o,o3 ui/ml

The aim of this study was to evaluate the local anesthetic solution, composed by Prilocaine 3% and felipressin 0,03 UI/ml, influence on the alveolar repair process in rats after dental extraction. This research was previously approved by the Ethic Committee in Research of the Masters Degree Program in Oral and Maxillofacial Surgery of the Marília University (UNIMAR), Marília, São Paulo, Brazil. It was an experimental, randomly controlled study, with bifactorial analysis (group control versus experimental group, in function of the postoperative times (2 X 4)). For the accomplishment of this study 32 rats were used (Rattus norvegicus, albinus, Wistar), males, adults, weighing between 280 and 320 grams. The animals were selected and divided into Group I (control) and Group II (Citocain 3%® - Prilocaine 3% with felipressin 0,03UI/ml) with 16 rats each; being four animals of the Group I and four of the Group II, destined to the euthanasia in the postoperative periods of 3rd, 7th, 15th and 24th days. The histological analysis with base in the developed methodology, allowed us to conclude that the anesthetic solution of Citocain 3%® applied with gauze compress on the surgical dental wound, produced tissue events that committed the basic biological principles, that are responsible for the regeneration of the gingival epithelium and the alveolar process repair in rats. The Group I presented better results in the alveolar repair when compared to the Group II.

Efeitos de drogas antiplaquetárias na doença periodontal

The association between platelets, angiogenesis and progression or repair of periodontal disease has been little explored and, consequently, the results are inconclusive. The pathogenic bacteria present in the periodontal pocket release endotoxins that affect the endothelial integrity and are able to induce the production of chemical mediators derived from plasma proteins and blood clotting while altering platelet function. There is great interest in the modulation of platelet activity in vascular disorders, especially cardiovascular diseases. For this reason, antiplatelet drugs, that are commonly used in the prevention of thromboembolic diseases, such as myocardial infarction, ischemic stroke and peripheral arterial disease, have been used. Aspirin is the only non-steroidal antiinflammatory agent with antiplatelet activity. In the periodontium, instead of only reduces levels of inflammatory cytokines, also significantly affects bleeding on probing, suggesting a dose-dependent modulation of periodontitis. In contrast, clopidogrel and ticlopidine are thienopyridine drugs with no known antiinflammatory action, suggesting that this benefit is related to an antiinflammatory effect indirectly correlated to their antiplatelet activity already established. In the literature there is limited information about the effect of these drugs on periodontium and periodontal disease development. Antiplatelet drugs hypothetically can change both the pathogenesis of periodontitis and subsequent periodontal tissue repair by blocking the secretion of chemical mediators which in general are important in modulating inflammation and tissue repair.

Análise histomorfométrica do reparo ósseo em tíbias de ratos castrados submetidos ao efeito do alendronato sódico

This study used histomorphometric analysis to investigate the effect of sodium alendronate, used for the treatment of osteoporosis, on the repair of surgically-induced bone defects in the tibia of castrated rats. Methods: The castrated animals were given subcutaneous injections of sodium alendronate (0.7mg/Kg) diluted in saline once a week; the control animals were given the same dose of saline. At 16, 30 and 44 days after the first injection of sodium alendronate, the animals were sacrificed and the right tibias were removed and processed for histomorphometric analysis. The volumetric bone mineral density was estimated by a reticular grid (25 points) attached to a light microscope. The number of points on the bone tissue was counted in the histological sections, totaling 100 points/animal. Results: The results revealed that sodium alendronate stimulated bone formation in castrated rats in all occasions, mainly at 16 and 30 days. Conclusion: Sodium alendronate affects mineral homeostasis, promoting bone repair.

Análise histomorfométrica da influência do Alendronato sódico no processo de reparo ósseo em tíbia de ratas submetidas a ovariectomia

The sodium alendronate (AS), considered as inhibitor in the osteoclasts- mediated bone resorption, promotes final effect of inhibition of resorption and increases bone mass. The objective of this research was to assess, by histomorphometry, the effect of sodium alendronate in repair bone of ovariectomized rats, in which there was performed a bone defect in the right tibia. The treated rats received a subcutaneous injection of sodic alendronate once a week, at 0.7 mg / kg, diluted with saline solution; the controls received the same volume of saline solution. In the periods of 16, 30 and 44 days after the first dose of AS, the animals were sacrificed, the right tibia was removed and processed for histomorphometric analysis. Four non-serial fields were used for the density volume quantification utilizing an integrative eyepiece with 25 points, totalizing 100 points per animal. Based on the results, the present study concludes that the ovariectomy induced osteoporosis and that the AS stimulated the bone formation. In addition, the ovariectomy decreased the estrogen levels. However, this procedure did not significantly influence the action of sodic alendronate.

Pinos transcorticais e gesso associados à aplicação local de plasma rico em plaquetas no tratamento de fratura do III metatarsiano em potro

In horses less than one year of age fractures of the third metacarpal bone (McIII) or metatarsal bone III (MtIII) are mainly attributed to trauma. Open reduction and internal fixation are the most common treatment method. A Quarter Horse filly with three months of age, which weighed 150kg presented a diaphyseal multifragmentar wedge fracture of right MtIII which was treated with transcortical pins and cast, associated with intralesional application of platelet rich plasma (PRP). After two years of surgery, the animal initiated a training program for racing, and six months later, the patient ran its first official match. The choice of therapeutic methods for treating fractures in horses should be one that provides an earlier repair and minor possibility of complications. Thus, the therapy association which was adopted was considered favorable, since allowed full reestablishment of locomotion of the patient and made possible its return to race.
