    Monografia (graduação)—Universidade de Brasília, Instituto de Artes, Departamento de Artes Cênicas, 2013.O presente trabalho é o resultado monográfico do curso de Bacharelado em Interpretação, que busca apontar o teatro como manipulador-político social da (re)interpretação de uma realidade cotidiana, ampliando o olhar para a problemática racial, levantando temas como racismo, mito da “democracia racial”, e o processo de construção identitária do corpo negro. Para isso, defendo a construção do espetáculo “Pentes” como uma expressão da linguagem do teatro negro e busco refletir a sua estética e “forma” de (re)interpretação social como arte política. Divido esta pesquisa em três capítulos que refletem a minha trajetória de vida e também a escolha da linha dramatúrgica do presente espetáculo; sendo eles: a negação, transição e afirmação. Desta maneira, nos dois primeiros, busco levantar algumas negações e transições da problemática racial no país, para assim, chegar ao último capítulo que dedico à afirmação da construção da cena “Pentes”, na qual busco colocar a importância da afirmação dos cabelos crespos como forma de resgate de identificação. Todo esse estudo está embasado nos conhecimentos dos Estudos Culturais, que tem um histórico de questionamento sobre o estabelecimento de hierarquias e alteridades entre as formas e práticas culturais. Essa linha de pesquisa dialoga diretamente com os meus anseios teatrais, pois ela busca instrumentalizar o saber conquistado em prol de uma nítida intervenção na esfera político social

    Research on cancer stem cells (CSCs) has greatly increased in the field of medicine and pathology; however, some conceptual misunderstandings are still present among the public as well as within the general scientific community that is not yet familiar with the subject. The very first problem is the misinterpretation of CSCs as a synonym of their normal counterparts, the well-known stem cells (SCs). Particularly in Dentistry, another common mistake is the misinterpretation of oral CSCs as normal tooth-derived SCs. The present review aims to clarify important concepts related to normal SCs and CSCs, as well as discuss the relevance of CSCs to the development, metastasis and therapy resistance of oral squamous cell carcinoma

    Anxiety in dental patients is a problem for both dental surgeons and patients. Thus, therapies that aim to control this anxiety and thus favor the patient's collaboration during treatment become factors frequently studied in search of the best alternative for this purpose. Therefore, the objective of this work is to review in the literature the use of herbal medicines in the control of dental anxiety. The bibliographic search was carried out in the databases ScienceDirect, Web of Science, Scielo, Pubmed, The Cochrane Library. 57 articles were included in this study. Research evidence points to Valeriana officinalis and Passiflora incarnata as the most studied herbal medicines for controlling anxiety and adverse effects. Studies prove the relative safety in the use of these drugs, as well as their effectiveness, low cost, less concentration of active ingredients with better effects and lesser side effects when compared to benzodiazepines. However, the use of these medicinal plants requires further clarification as to their real effectiveness, correct dosage and side effects in conscious sedation in Dentistry.La ansiedad en los pacientes dentales es un problema tanto para los cirujanos dentales como para los pacientes.

    Radiation-related caries are one the most undesired reactions manifested during or after head and neck radiotherapy. Fluoride application is an important strategy to reduce demineralization and enhance remineralizaton. Objective: To evaluate the effect of the topical application of fluoride during irradiation on dental enamel demineralization. Material and Methods: Thirty molars were randomly divided into three groups: Non-irradiated (NI), Irradiated (I), Irradiated with fluoride (IF). Each group was subdivided according to the presence or absence of pH-cycling (n=5). In the irradiated groups, the teeth received 70 Gy. The enamel’s chemical composition was measured using Fourier Transform Infrared Spectrometry (organic matrix/mineral ratio – M/M and relative carbonate content - RCC). Vickers microhardness (VHN) and elastic modulus (E) were evaluated at three depths (surface, middle and deep enamel). Scanning electron microscopy (SEM) was used to assess the enamel’s morphology. Results: The FTIR analysis (M/M and RCC) showed significant differences for irradiation, pH-cycling and the interaction between factors (p<0.001). Without pH-cycling, IF had the lowest organic matrix/mineral ratio and relative carbonate content. With pH-cycling, the organic matrix/mineral ratio increased and the relative carbonate content decreased, except for IF. VHN was influenced only by pH-cycling (p<0.001), which generated higher VHN values. ANOVA detected significant differences in E for irradiation (p<0.001), pH-cycling (p<0.001) and for the interaction between irradiation and pH-cycling (p<0.001). Increased E was found for group I without pH-cycling. With pH-cycling, groups I and IF were similar, and showed higher values than NI. The SEM images showed no morphological changes without pH-cycling. With pH-cycling, fluoride helped to maintain the outer enamel’s morphology. Conclusions: Fluoride reduced mineral loss and maintained the outer morphology of irradiated and cycled enamel. However, it was not as effective in preserving the mechanical properties of enamel. Radiotherapy altered the enamel’s elastic modulus and its chemical composition

    Get PDF
    Xeroderma Pigmentosum is a rare autosomal recessive genetic disorder characterized by defective DNA repair leading to clinical and cellular hypersensitivity to ultraviolet radiation and carcinogenic agents. Important clinical features are: intense cutaneous photosensitivity, xerosis, poikiloderma, actinic keratosis, acute burning under minimal sun exposure, erythemas, hyperpigmented lentiginous macules, and malignant lesions in sun-exposed areas, including basocellular carcinoma, squamous cell carcinoma, and melanoma. There is a great involvement of many parts of the body, especially head and neck. The oral manifestations are mainly related to the occurrence of malignant tumors in the lips, tongue and buccal mucosa. This paper reports a rare case of Xeroderma Pigmentosum in a 41-year-old male presenting mainly dermatological, neurological and ophthalmological involvement. Oral implications such as severe oral pain and mouth opening limitation were present due to perioral scars. In addition, this paper discuss some important aspects concerning the role of the dental professional management of this entity, since XP patients require constant dental care and follow-up in order to control the occurrence of new lesions on the lips or inside oral cavity

    Genes encoding Shiga toxin and the intimin receptor detected in faecal samples collected from wild canids

    Background: Enteropathogenic Escherichia coli (EPEC) and Shiga toxin-producing E. coli (STEC) are diarrheagenic E. coli that can cause disease in humans. The pathotype EPEC leads to the attaching and effacing lesion, causing damage to the microvilli following to diarrhea. STEC pathotypes produces cytotoxins, which in humans are responsible for hemorrhagic colitis or hemolytic uremic syndrome. Animals are the reservoirs of these pathotypes, especially ruminants. However, other animal’s species can be associated as carriers of EPEC and STEC strains. The aim of this study was to analyze wild canid crab-eating fox (Cerdocyon thous) as potential natural carriers of STEC and EPEC E. coli. Materials, Methods & Results: Seven fecal samples were analyzed from the crab-eating fox of free-living, captured in a peri-urban area. Samples were collected from the rectal ampulla, and the animals were clinic evaluated, being considered healthy at the captured moment. The feces were inoculated on medium MacConkey agar, and then the plates were incubated at 37°C for 24 h. All colony forming units (CFU) were collected by plate washing with ultrapure water (2 mL) and posterior freezing at -20°C. The total bacterial DNA from the CFU collected was extracted, followed by PCR assay to search for three genes: stx1, stx2 (responsible for the synthesis of the Shiga toxin) and tir, which encodes the translocated intimin receptor, related to the A/E lesion formation. Three samples were detected as positive, being one animal detected as carrier of the stx2 gene (STEC strain), while two animals were identified as carrier of the tir gene (EPEC strains).The stx1 gene was not identified on the samples. Also, in the samples, only the presence of one gene studied at a time was observed. Therefore, we have found out that the crab-eating fox can act as reservoirs of STEC and EPEC strains. Discussion: The carrier’s animals of STEC and EPEC strains do not have receptors for the Shiga toxin, serving as asymptomatic vehicle. The wild canids collected and positives to STEC and EPEC E. coli strains analyzed here, did not shown any clinical signs, wherefore they have the potential of being a source of pathogens to other animals and even humans. The observation of this additional wild species, the crab-eating fox, as carriers of STEC and EPEC reinforces the importance of monitoring wild species and the need for caution because of the potential zoonosis. Nevertheless, there are other species of wild animals that were described as rarely-carriers of these pathogens, like deer, wild ruminants and birds. These E. coli pathotypes, potentially foodborne zoonotic pathogens, are acquired by humans from food and water contaminated, by oral-fecal route, or by direct contact with carries animals and their feces. The human contact with wild animals is getting ordinary; because of that, wild animals, like wild canids, may constitute a considerable risk to animal and humans health, mostly by the transmission of these bacteria strains to the environment. In conclusion, the identification of genes encoding Shiga toxin and the intimin receptor in wild canids feces highlight that STEC and EPEC pathogens could be spread by these wild animals. We reinforce that STEC and EPEC pathogens could be naturally carried by wild animals, such as the crab-eating fox, and therefore, is needed further research for better understanding their potential effect, and also the interaction between the pathogen and the host

    As patologias ovarianas são um grupo heterogêneo de doenças e incluem um grande percentual de alterações benignas e um número menor de neoplasias malignas, que apresenta a maior taxa de letalidade entre todos os tumores ginecológicos, e representam 30% dos cânceres ginecológicos no Brasil. O estudo configura-se como observacional, analítico e transversal e avalia o percentual de neoplasias malignas, benignas e borderline nos resultados histopatológicos de biópsias de ovário analisadas em um laboratório de referência em patologia, em Brasília, entre 2015 e 2020, descrevendo o perfil etário das pacientes e os subtipos de tais neoplasias, resultando na seleção de 3.348 pacientes. Entre elas, observou-se que a maioria possuía entre 20 e 49 anos, totalizando 61,70% dos casos. Em relação às neoplasias malignas, das 1.174 amostras, 64,4% eram de pacientes com mais de 50 anos. A origem das pacientes foi predominantemente do sistema particular, sendo apenas 21 (0,63%) provenientes do serviço público; dessas, seis (28,6%) obtiveram diagnóstico de neoplasias malignas, caracterizando maior percentual de número de casos malignos provenientes do setor público. Mais da metade dos resultados das biópsias ovarianas foi normal (58,24%). Entre as patologias ovarianas, as neoplasias benignas foram as mais frequentes (21,23%); dessas, o teratoma cistico maduro representou a maioria (40,37%). Os casos de endometrioma e endometriose abrangeram 12,27% do total das biópsias. Os tumores malignos (7,38%) e borderline (2,27%) de ovário representaram 9,65% dos casos analisados no período, no total de 323 casos. O tipo histológico epitelial representou 62,35% das neoplasias malignas, e, entre essas, o adenocarcinoma seroso foi o mais comum (47,4% dos casos). Curiosamente, os tumores do cordão sexual foram mais frequentes do que os de células germinativas nesta pesquisa (31,58 % x 6,07%), especialmente pelo número de tumores de células estromais da granulosa (72 casos no período). Metade das metástases para ovário foi originada no intestino. O câncer de ovário é um tema de extrema relevância na ginecologia, seja pela dificuldade de rastreio e diagnóstico precoces, seja pela alta prevalência na população feminina. É necessário maior desenvolvimento científico e pesquisa nesse campo da ciência. Esse estudo é uma tentativa de resumir dados epidemiológicos regionais que contribuirão na construção de futuros projetos
