Abordagem cognitiva da construção deverbal x-dor: contribuições para o ensino do português

This work analyzes deverbal nominalizations with the sufix dor in Brazilian Portuguese, under the perspective of Cognitive Linguistics, more specifically, the Construction Grammar. The aim is to determine the general features of interpretation that characterize this deverbal construction and its use in formal writing. Based on the cognitive assumption that grammatical structure is motivated, explained, and determined by the structure of cognitive patterns, created from our experience in the world, and by the communicative function of language, the dor deverbal is treated as a polysemic grammatical construction. In the composition of V+dor, the relation rootsuffix is focused, through a characterization of the syntactic-semantic nature of the verb and the values of the suffix. Among the different values conventionally related to the XDOR construction, the agentive is considered as the prototypical sense. The relation between the other values and the prototype is explained by cognitive abilities and discourse motivations. The deverbal construction X-DOR is also interpreted as a valency noun that, like an action nominal, retains the argument structure of the deriving predicate. It is also intended to demonstrate the textual function of this deverbal construction, as a device of information condensing and anaphoric recovery. The data were taken from Veja magazine and the approach is qualitative (explicative), with quantitative support

Análise textual dos discursos: responsabilidade enunciativa no texto jurídico

This investigation aims at describing, analyzing and interpreting the Commitment in Initial Petitions, which is a genre circumscribed in the judicial domain. For this purpose, we have chosen sections, facts as found and relevant law , sections of the petition, with the understanding that, in this way, respectively, the narration of events, which gives margin to the propositioning to the judicial action, and the exposition of the law that upholds the author s intention. We base our discussion on the field of Linguistics, more precisely, Textual Discourse Analysis (TDA), whose theoretical basis is derived from Textual Linguistics (TL) and Enunciative Linguistics. We foreground, particularly, the way in which the author of texts, objects of analysis, use discursive strategies that evidence ER. The relevance of this study, then, is in the formation of a critique of the judicial text, as it conceives of a dialogical approach to the point of view, raising not only questions about the way in which a linguistic instance conceives an object of discourse, but also considering questions of language inherent to technical writing and, in this aspect, contributing to the work of those operating in Law about the many ways ER is formed in the body of a petition. We selected two categories to analyze that, according to Adam (2011), characterize the degree of ER in the textual material of the propositional enunciations: the different types of representation of speech and the indications of profile of mediators. In this sense, with this task as an objective, we base our study regarding point of view on Rabatel (2003, 2009a, 2010) with relation to the enunciative approach, including the study of PDV in polyphonic and dialogical theoretical framework to study the ER from different types of speech representations that conceive forms of transmission of discourse and the role of the enunciating subject, mainly the responsibility and the prerogative by the propositional contents. In the same way, intending to study the indications of the mediator profiles, we observed the postulations of Guentchéva (1994, 1996), which develop the notion of mediative grammatical categories, of which permit the linguistic marking of distance and engagement of the enunciator with regard to the information expressed. The methodology we adopted was based on qualitative research, of an interpretive and introspective nature, in light of the fact that his study focuses on processes and strategies underlying language use. The corpus of the research is comprised of Initial Petitions, which gave rise to actions originating in the Civil Court of Currais Novos County RN. The data analysis shows that an object of discourse is always perspective oriented and presents the point of view of one or more enunciators. Consequently, the producer of a text, using the PDV of other enunciators, influences and establishes the argumentative orientation of the text. In the same way, it evidences the relevance of the use of mediated constructions in the judicial text, as they function as strategies attenuated to the responsibility of the producer of the text with what is said, and at the same time points to a discourse of authority through the entrance of the sources of law. Moreover, it reveals the documental and international importance of this practice, at the same time that it exposes the compositional and normative difficulties with regard to legal and linguistic aspects

Da emergência da personagem social do homosexual à cultura gay: uma leitura a partir de Michel Foucault

This present research aims to understand the concept of homosexuality as a social creation that comes permeated by the discourses of sexuality devices. It discusses the issue of homosexuality with a focus on works of Michel Foucault, in special The History of Sexuality, where the author emphasizes that homosexuality as a social construct that manifests itself during the nineteenth century. From the Foucauldian discourse, it is proposed to understand and analyze the creation of the concept of homosexuality, which is built around the subordination of the individual as a social agent, or the creation of homosexuality does not refer to sexual intercourse between individuals of the same sex, but a social subject and the position it takes in society. So along with the birth of the homosexual individual, there is also the construction of the individual as a social subject, as being, homosexuality and homosexual subject are products of overlapping powerculture. When addressing this theme, it breaks the hegemony that seeks to characterize naturalized of sexuality and, consequently, homosexuality, born with the original speeches on medical and psychiatric couches, in which one perceives the role of power in the discourses deploying the truths aimed at sexuality. With this, there has been an argument that seeks to refute the eugenics that includes sexuality as something natural, instituting a homosexual as a guy born hostage to a bad genetic and abnormal who should be treated for their disease, and understand this individual as a product of social discourse

Grau de conhecimento de pacientes sobre o acidente vascular cerebral e a necessidade do uso de cartilha educativa para orientação fisioterapêutica

Stroke is a neurological dysfunction of vascular origin that causes physical impairments and disabilities. Brazil leads the statistics stroke mortality among Latin American countries, demonstrating still be a neglected disease in this country. The incidence is related to risk factors and still is great misinformation in our country about stroke, treatment and prophylaxis. The aim of this study was to assess the degree of knowledge about stroke and patients need to use educational booklet for physiotherapy. The sample consisted of 53 patients, 22 females and 31 males, mean age 56.2 ± 10.9 years. Patients were evaluated by completing questionnaires, observing the socio-demographic and clinical aspects, neurological assessment, functional assessment, knowledge of pathology and presenting educational booklet. The data were analyzed using the chi-square test. According to the results, it was observed that the patients had not enough knowledge about the terminology, complications and warning signs of stroke, were not aware and did not perform the proper positioning of the limb and transfers, however, were aware and performed the stretching maneuvers. This reveals the need to implement policies that lead to information about stroke population. Following discharge from outpatient physical therapy using educational booklets with guidelines on positioning, stretching exercises and transfer is important in functional rehabilitation and encouraging independence of the individual affected by stroke

Análise do sono e da utilização de cartilhas educativas em pacientes com acidente vascular cerebral

O AVC é uma grande causa de mortalidade e uma das principais causas de incapacidade entre adultos. O presente estudo visa analisar o estado do sono e da utilização de cartilhas educativas em pacientes com AVC. No primeiro estudo foram abordados os fatores associados com os horários de dormir/acordar e no segundo estudo foi analisado o conhecimento e prática quanto às orientações sobre os hábitos de sono e estimulação cognitiva. No estudo 1 foram avaliados 50 pacientes sendo 28 homens, de faixa etária entre 25 e 90 anos que durante uma semana completaram um diário do sono e o registro de atividades através do Social Rhythm Metric (SRM) e do Indice de Nível de Atividades (ALI) e aplicação do questionário de cronotipo (MEQ). Utilizado o teste de correlação de Spearman verificou-se correlação significativa entre os horários de dormir/acordar com cronotipo e entre os horários de dormir/acordar com SRM e o ALI. No segundo estudo foram abordados 40 pacientes com idade média 56,1 ± 11,9 anos, sendo 15 homens e 25 mulheres; como instrumentos foram utilizados National Institute Health Stroke Scale (NIHSS) e em seguida os pacientes observaram cartilhas educativas sobre hábitos de sono e estimulação cognitiva respondendo se conheciam e se praticavam as orientações apresentadas. A análise estatística realizada através do teste de Fisher obteve como resultado, que das 10 orientações apresentadas sobre os hábitos de sono, 6 foram citadas como conhecidas e apenas 4 foram praticadas. Das 6 orientações cognitivas, não houve diferença significativa entre os que conheciam e não conheciam, mas em 5 delas a maior frequência foi dos pacientes que não praticaram. Os resultados dos estudos indicam a importância de avaliar o cronotipo antes do planejamento de reabilitação, e a necessidade de se estimular o ritmo social a fim de contribuir para a melhoria dos padrões de sono de pacientes. Verificou-se também que em relação ao conhecimento e prática de orientações apresentadas muitos pacientes não conheceram ou não praticaram orientações importantes a respeito de hábitos de sono e de estimulação cognitiva, mesmo na fase crônica da patologia, sugerindo que mais políticas de educação em saúde devem ser implementadas com intuito de causar mudança nos hábitos de vida dos pacientes com AVC

Caracterização dos genes scMUTM1 e scMUTM2 de cana-de-açúcar

Plants are organisms sessile and because of this they are susceptible to genotoxic effects due to environmental exposure such as light [including ultraviolet (UV)], heat, drought and chemicals agents. Therefore, there are differents pathways in order to detect a lesion and correct. These pathways are not well known in plants. The MutM/Fpg protein is a DNA glycosylase that is responsible for detect and correct oxidative lesions. In the sugarcane genome, it was found two possible cDNAs that had homology to this protein: scMUTM1 and scMUTM2. The aim of this work was to characterize the role of these cDNAs in plants. In order to do this, the expression level after oxidative stress was evaluated by semiquantitative RT-PCR. Another point analyzed in order to obtain the full-length gene, it was to use a sugarcane genomic library that was hybridized with both cDNAs as a probe. It was found two clones that will bought and sequenced. The promoter region was also cloned. It was obtained sequences only for scMUTM2 promoter region. The sequences obtained were divided into six groups. It was found regulatory motifs such as TATA-box, CAAT-box, oxidative stress element response and regulatory regions that response to light. The other point analyzed was to characterize the N-terminal region by PCR constructs. These constructs have deletions at 5 region. These sequences were introduce into Escherichia coli wild type strain (CC104) and double mutant (CC104mutMmutY). The results showed that proteins with deletions of scMUTM1 N-terminal region were able to complement the Fpg and MutY-glycosylase deficiency in CC104 mutMmutY reducing the spontaneous mutation frequency

Patrimônio, Memória e Espaço: a construção da paisagem açucareira do Vale do Ceará-Mirim

This work aims to understand how the installation of sugar culture along the river Ceará-Mirim defined the spatial organization of the Valley, and thus setting the landscape. This space has begun to be defined only in the second half of the nineteenth century, when the sugarcane growth had atarted on land located on the banks of the river Ceará-Mirim. The passage of this period of great prosperity can be seen through the heritage material which is still presented in the region. Walking through the Valley, we found a considerable number of architectural buildings, many in ruins, linked to this historical moment. This perception, caused by these buildings, will take us on a trip to the past, back to a time characterized by great-houses, mills, sugarcane plantations, planters, slaves, etc. The references that lead us to consider the sugar mills located along the valley of Ceará Mirim as a patrimony, which carry an entire historical baggage, guide us to the first half of the twentieth century. During this period, the role of intellectuals from the Rio - Sao Paulo through the modernist movement will be decisive in the formation of a national identity. The heritage material identified along the valley of Ceará Mirim defined its current spatial organization, setting the landscape. But we must conceive this landscape into two ways: first, as a material representation of social practices carried out in this space, where social, cultural, economic and environmental aspects have interacted to their training; as well as a landscape that carries a whole historical baggage which was built throughout the twentieth century

Contando o passado, tecendo a saudade: a construção simbólica do engenho açucareiro em Jose Lins do Rego (1919-1943)

In this work I have searched the symbolical sense of a specific place. I have started from the theoretical assumption that places are social relations resulting from material and symbolical conditions developed in a certain time and by certain factors. In this sense, I have analyzed the symbolical aspect of sugar plantation from some literary works created by the writer José Lins do Rego from the state of Paraíba. I intend to analyze the symbolical dimension senses, values and images used by this writer to show the sugar plantation. Giving special attention to the works from the named cycle of sugar plantation , I have searched for the senses and meanings used in José Lins do Rego literary discourse to create a fictional sugar plantation, showing this place in a specific way. Based in cultural history, I have used several sources: literary works, prefaces of books, memory works, journalistic works, letters written by intellectual men and history books. My time of analysis is from 1919 the beginning of José Lins do Rego s intellectual activity - until 1943 publication of Fogo Morto, last literary work that I have analyzed. In symbolical terms, what is sugar plantation, this place that has totally touched José Lins do Regos life and literary work? That was the structural question that has determined the present research

Comprovação da real comunicação entre o endodonto e o periodonto através do canal cavo inter-radicular e sua prevalência em molares inferiores humanos

The neurovascular system of the pulp and of the periodontium is interconnected and among the possible intercommunications between these two tissues, there is the cavo inter-radicular canal. It is a small canal that goes through any inter-radicular dentine and arises in the furca region of the multi-radicular teeth. Its predominance has been studied in the literature, by several methodologies, with divergent results. The objective of this work was to establish, in vitro, the predominance of the cavo inter-radicular canal, in human lower molars, through the diaphanization technique and dye leakage. For this research, 140 teeth (100 first and second 40 lower molars) were selected, extracted due to different reasons, belonging to a teeth bank of the Endodontics discipline of the Dentistry College at Federal University of Rio Grande do Norte. The teeth were preserved in formol until the moment of use and immersed in physiological solution. Had the endodontic access fulfilled and the whole external surface, except for the furcation, sealed with two layers of nail enamel. The cleaning of the pulpar chamber floor was carried out with sodium hypochlorite solution 5%, being this solution renewed every 5 minutes, during 1 hour. The teeth were immersed in Indian dye and, after drying of the dye, they had their crowns split up in the amelo-cemental junction. Then, they were examined in a stereomicroscope, where marks of the coloring were observed in the furcation and on the pulpar floor. After this recording, the sample was diaphanized and with the transparent teeth, it was possible to observe in the stereomicroscope, the true inter-radicular canals. As a result of this experiment, the presence of these canals was observed in 13 % of the first and 7, 5 % of the second evaluated molars. The study showed that both the presence of the cavo inter-radicular canal is real and the diaphanization and dye leakage is an efficient method for this type of research

Expressão imuno-histoquímica metaloproteinase -1, -2 e -9 em ameloblastoma sólido e tumor odontogênico adematóide

Ameloblastoma and adenomatoid odontogenic tumor are odontogenic tumors arising from the odontogenic epithelium with distinct clinical behavior. In attempt to comprehend the interaction between the odontogenic tumor cells and the extracellular matrix, the present work evaluated and compared the immunohistochemical expression of the matrix metalloproteinases-1 (MMP-1), -2 (MMP-2) and -9 (MMP-9) in 20 cases of ameloblastoma and 10 adenomatoid odontogenic tumor. MMP-1 exhibited exuberant expression in the parenchyma and in the stroma of both studied tumors, while the MMP-2 showed varied expression with about of 80% and 60% of the neoplastic cells exhibiting positivity in the ameloblastoma and adenomatoid odontogenic tumor, respectively. With relation to the MMP-2 expression by the mesenchymal cells, it was observed that 65% of the ameloblastoma and 80% of the adenomatoid odontogenic tumor were positive. The immunoreactivity of MMP-9 was detected in all studied cases, although its expression had occurred predominantely in less than 50% of the parenchyma cells of the ameloblastoma, while in about of 60% of the adenomatoid odontogenic tumor more than 50% of cells were positive. The mesenchymal cells were positive to MMP-9 in 65% of the ameloblastoma and in 80% of the adenomatoid odontogenic tumor, respectively. Statistically significant difference was observed to the MMP-1 expression with relation to MMP-2 and MMP-9 in the ameloblastoma (p < 0.001). It was not possible to perform statistical analysis to the cases of adenomatoid odontogenic tumor, however there was a tendency toward a differential expression of the MMP-1 with relation to other studied MMPs. These results suggest that MMP-1, - 2 and -9 are implicated in the growth and progression of both tumors analyzed as well as the more pronounced participation of the stroma in the ameloblastoma could together to be related to the higher clinical aggressiveness

Análise quantitativa das células CD4 e sua importância no diagnóstico de lesões orais em pacientes HIV positivos

The oral manifestations due to HIV infection are, a lot of times, the first clinical signs of the disease. These injuries may also function as beepers and sentries of the curse and progression of the HIV infection and AIDS. The objective of this work was to evaluate the prevalence of the oral injuries in HIV positive patients, relating them with the CD4+ cells counting and the viral load in patients from the Hospital of Infected contagious Gizelda Trigueiro in Natal-RN. One hundred and one patients were evaluated, where after the clinical exam of the oral cavity, these ones were conducted to the peripheral blood collection for the counting of CD4+ lymphocytes. We observed a prevalence of 25,6%, that is, 31 cases. The Oral Candidiasis was the most commum injure, followed by Oral Hairy Leukoplakia, linear gingival erytema, lips herpes, gingivitis and periodontitis - HIV. The average counting of cells CD4+ of the injury carrying patients was of 250 cells/mm3. We did not observe relation between the presence of injuries and the viral load of the individuals

Estudo da angiogênese pelo CD105 e FvW no carcinoma epidermóide oral e sua relação com o estadiamento clínico do tumor

The purpose of this study was to assess the immunohistochemical expression of CD105 and FvW antibodies in the angiogenesis of oral epidermoid carcinoma (OEC), correlating it with the TNM clinical staging system, seeking a better understanding of its biological behavior and use as an indicator of prognosis.The sample consisted of 30 epidermoid carcinoma (EC) cases, 10 of the floor of the mouth, 10 of the retromolar region and 10 of the tongue, in addition to 10 cases of pyogenic granuloma, which made up the control group. The results showed that mean microvessel counts (MVC) were correspondingly higher in the pyogenic granuloma group (CD105 = 57.26 vessels and FvW = 39.64) than in the EC group (CD105 = 10.09 and FvW = 12.20) and that the differences were statistically significant between the groups for each of the angiogenic biomarkers (p = 0.002 for CD105 and p< 0.001 for FvW). CD105 had better positivity in the pyogenic granuloma group (mean = 57.26 vessels) and for EC, FvW had the highest expression (mean = 12.20 vessels). With respect to EC, the most affected age group was between 51 and 70 years (n = 14; 46.7%), with a representative MVC for both markers. No statistically significant difference was found between the sexes for any of the markers (p = 0.967 for CD105 and p = 0.744 for FvW). Mean CD105 levels were much higher in patients with stage T3 and T4 (17.13) and lower in those with stage N+ (6.36). Mean FvW levels were higher in the patients with stage T1 and T2 (12.23) and lower in patients with T3 and T4 (12.10), but without a statistically significant difference. In regard to anatomic location, a statistically significant difference was observed between FvW sites, with a statistically significant difference between floor of the mouth cases and those located in the retromolar region (p =0.013). Therefore, this study suggests that CD105 expression in OEC angiogenesis, in contrast to other types of malignant neoplasias, may not be correlated with prognosis and tumor aggressiveness, whereas FvW was a more effective antibody for staining this lesion

Expressão imuno-histoquímica dos marcadores angiogênicos CD105 (endoglina) e CD34 em hemangiomas e granulomas piogênicos orais

Angiogenesis, a fundamental mechanism in tumor development, is used for differential diagnosis and prognosis purposes in various neoplasias of the head and neck. This study proposes to assess angiogenic activity using immunohistochemical expression by anti-CD105 and anti-CD34 antibodies in 20 cases of hemangiomas and 20 cases of oral pyogenic granulomas, in addition to determining the usefulness of these markers as one of the differential diagnosis resources for these two oral lesions. The results showed no statistically significant difference between microvascular count (MVC) means determined by anti-CD105 (p = 0.803) and anti-CD34 (p = 0.279) antibodies. The mean number of vessels obtained by MVC in the oral hemangiomas immunostained by anti-CD105 and anti-CD34 was 18.75 and 59.72, respectively, whereas in the oral pyogenic granulomas, the mean number was 20.22 and 48.09 respectively. It was also shown that CD34 was more effective than CD105 in identifying blood vessels. However, it must be pointed out that the anti-CD105 antibody seems to be more related to vascular neoformation. Overall, this assay reinforces the role of angiogenic factors in the etiopathogenesis of hemangiomas and oral pyogenic granulomas, but the results showed that angiogenesis quantification cannot be used as a differential diagnosis parameter between the two lesions analyzed

Imunoexpressão das claudinas -1 e -7 em ameloblastomas e germes dentais humanos

We investigated the immunohistochemistry expression of claudins -1 and -7 in ameloblastoma and in human dental germs on the pattern of distribution (focal, regional or diffuse), the cells that expressed (if central or peripheral) and the location of that expression in the cell components recital membrane, cytoplasm and nucleus. Among the 29 cases of ameloblastoma, 24 were type solid and 6 unicystic. In 7 mandibular specimens of human fetuses found dental germs from the stage of bud to the crown. We note that the pattern of expression in the dental germs was variable for claudinas studied according to the cell type and stage of differentiation and was invariate only in the cells of stellate reticulum. In epithelium internal of enamel organ, claudin-1 has been decreasing with the progression of differentiation as to claudina-7 that was found in the cells of the peripheral papilla. For ameloblastoma the expression was more significant than that observed in dental germs. Fisher s exact test no found association between the expression of claudinas cells in central and peripheral and the type of ameloblastoma (solid or unicystic). Thus, in general the claudin-1 was positive in the central cell of 93,1% of the cases and in peripheral cells of 51,7%. The claudin-7 was expressed in the cells of all cases central and peripheral cells from 89,7%. For both claudins the distribution was predominantly diffuse cells both in central and peripheral cells. Given our findings it is suggested that the expression of claudins may be indicative of the involvement of these molecules in morphogenetics events culminating with the dental development and that possibly influence the development of neoplastic ameloblastoma

Expressão Imuno-histoquímica da triptase em mastócitos nos Fibromas de Células Gigantes e Hiperplasias Fibrosas de Mucosa Oral

The giant cell fibroma is a benign neoplasm characterized by the presence of mono, bi or multinucleate cells, which can have a connection to the presence of mast cells. This research aims to analyze, descriptively and comparatively, the immunohystochemistry expression of the tryptase in mast cells of the giant cell f ibroma, f ibrous hyperplasia and samples of the normal oral mucosa. Thirty cases of giant cell fibroma, ten cases of fibrous hyperplasia and ten cases of normal oral mucosa were selected for the analysis of the immunohistochemistry expression, determination of the number of present mast cells, as well as their location and shape. It could be stated that there was a statistically signif icant difference (p<0,001) in relation to the quantity of mast cells among other samples analyzed where the giant cell f ibroma presented lesser quantity of mast cell and the hyperplasia showed higher concentration of this cellular type. Although the oral mucosa has presented a higher quantity of mast cells when compared to the giant cells fibroma, these were found in usual locations in the connective tissue in normal tissues. There could be noticed a statistically significant difference in relation to the number of non-granulated mast cells (p<0,001). On the areas of fibrosis, we could observe a statistically signif icant difference (p<0,006) among the samples. In relation to the present mast cells in perivascular location, no statistically signif icant difference was found. On the morphological analysis there was a predominance of oval mast cells. It was concluded that despite of the fact there was a lesser quantity of mast cells present in cases of giant cell f ibroma, they appeared to have a stronger relation to the present giant fibroblasts in this lesions, around 59,62%, being also evidenced a strong relation between these cells and the fibrosis areas in both cases of giant cell f ibroma and f ibrous hyperplasias and samples of normal oral mucosa, used as control group in our study, confirming, this way, the role of the mast cells as fibrinogenous inductor
