Solidão de náufrago: a poética de Claudia Roquette-Pinto nos jardins de Corola

A obra Corola, de Claudia Roquette-Pinto (2000), apresenta um projeto poético consistente advindo do emprego de recursos expressivos metalinguísticos e da coesa estrutura da obra. O recurso à intratextualidade favorece a unidade e as reflexões metalinguísticas dos 48 poemas que compõem a obra. O diálogo com a tradição literária é simultâneo à consciência dos enunciadores de que a poesia de Corola é intervalar e físsil. Os 47 primeiros poemas sem título de Corola constroem forte relação de continuidade e interdependência reveladora da presença de uma “teoria” do fazer poético baseada em intempéries. O lirismo de Corola não apresenta marcas de autocomiseração em relação à situação de náufrago anunciada no último poema da obra. Os adjetivos exausto, roto, desacreditado, atribuídos ao eu poético, fazem com que ele se desdobre em outro, apreciador crítico de seus próprios ruídos poéticos e refém consciente de um tempo lacunar e intermitente que favorece a construção de uma poética da paciente espera pelo resgate da poesia e do desdobramento em leitor-espectador de si mesmo e do texto poético. Analisaremos alguns procedimentos metalingüísticos e as inquietações compositivas anunciadas pelos eus poéticos de Corola, além da recorrente figura do jardim como espaço poético.

Aspecto radiológico e macroscópico de matriz óssea mineralizada heteróloga fragmentada e polimetilmetacrilato autoclavados em falha óssea de tíbia de coelho

A segmental defect of 6mm diameter was performed in the medial metaphyseal region of the tibia of 12 rabbits. For the bone defect reconstruction there was implanted a combination of micro and macro fragments of heterologous fragmented cortical bone matrix preserved in glycerin (98%) and polymethylmethacrylate, both autoclaved. Radiological and macroscopic evaluation was performed at 30, 60, 90 and 120 days. Adhesion in relation to time of the micro and macro composites to the recipient bed was observed in 100% of the cases. This showed that this implant is biologically biocompatible, since it promoted bone defects repair, with no signs of infection, migration and/or rejection. In this way, this implant can be classified as one more option of substitute to fill large bone defects.

Produção de anticorpos monoclonais murinos dirigidos contra células-tronco mesenquimais de coelho

Mesenchymal stem cells (MSCs) are a heterogeneous population of cells that proliferate in vitro as plastic-adherent cells, have fibroblast-like morphology and can differentiate into bone, cartilage and fat cells. Therapeutic potential of MSCs have been studied in experimental models, such as rabbit, in Laboratory of Cell Engineering of Botucatu. However, no specific markers have been reported for expanded rabbit MSCs, which hampers the isolation of pure MSC populations by immunophenotypic characterization. Thus, the objective of this study was to produce monoclonal antibodies (mAbs) to rabbit MSCs. MSCs derived from rabbit bone marrow (BM) were isolated, cultured, expanded ex vivo, and immunized into three BALB/c mices, and spleen cells subsequently harvested were used to generate hibridoma cell lines secreting antibodies against MSCs. Hybridoma cells were screened by flow cytometry and antibody-producing cells were subjected to subsequent rounds of retests. MSC1-160 obtained the best positivity for IgG expression and was cloned by limiting dilutions and micromanipulation. Ascitic fluid from ten best clones was purified by affinity chromatography in Protein A-sepharose CL-4B column and purification control was performed by electrophoresis in agarose gels. The purified IgG were tested against rabbit MSCs, obtaining high positivity by flow Cytometry. In conclusion, we developed 10 mAbs, MSC1-160 A20, A30, A41, A47, A55, A60, A63, A69, A81, and A82, that recognize rabbit MSC cell surface antigens showing potential for immunophenotypic characterization of rabbit MSC cell lines

Comunicação pública e acesso à cultura: um estudo de caso da Oficina Cultural Glauco Pinto de Moraes sob a ótica das Relações Públicas

This study examined how public relations can work through the implementation of tools for public communication, to seek to ensure a citizen of their rights: access to culture. We chose as case study Oficina Cultural Glauco Pintio de Moraes, located in Bauru (SP), an instrument of policy implementation for the Sao Paulo area, to discuss how the actions are carried out to the community as a whole. We analyzed data pertaining to the activities offered by the workshop and suggested actions for communication and relationship with its public workshop to happen more efficiently

Influence of nicotine and cotinine impregnation on the first step of periodontal regeneration: clot stabilization

This study analyzes the clot stabilization on root surfaces of teeth impregnated with cotinine and nicotine and the influence of the scaling in the adhesion of blood components, observing the influence of new exposition to nicotine and/or cotinine after scaling. Fifteen human teeth extracted due to periodontal disease of non-smokers patients were selected and manually scaled. Four dentin blocks were obtained from each tooth (n = 60). Samples received blood application or reimpregnation with nicotine and/or cotinine, depending on the groups. Group 1: PBS immersion + root scaling + blood; group 2: nicotine + root scaling + blood; group 3: nicotine + root scaling + nicotine reapplication + blood; group 4: cotinine + root scaling + blood; group 5: cotinine + root scaling + cotinine reapplication+ blood; group 6: nicotine and cotinine + root scaling + nicotine and cotinine + blood. Samples were kept in 2 ml of each substance for 24 hours. Each group received a blood drop and was analyzed by SEM. The higher amount of blood components was present in teeth exposed to cotinine and the groups submitted to scaling and blood application in comparison with groups that received reapplication of toxic substances after scaling. The greater toxic effect on root dentin surface was after the exposure to nicotine and cotinine. Results suggest that periodontal healing may be delayed in smokers due to the direct inhibition of clot stabilization on the root surface when nicotine and cotinine are present concomitantly.

Dimensões das furcas de primeiros pré-molares superiores e sua relação com curetas periodontais

The aim of this in vitro study was to comparatively evaluate the mesio and distal furcation entrance measurements of first maxillary premolar. The measurements were compared with different curette blades. A caliper was used by an examinator to acquire the measurements of root trunk (TR); 1 mm (D1) and 2 mm (D2) both below the furcation entrance. For this study Gracey, Mini Gracey, Padua Lima (PL) and Goldman Fox 4 curettes (Millenium) were selected. Measurements of DT - total distance of the active blade length, DI - width of the active blade, DM - width of the medium part of the active blade were obtained for the curettes. The measurements were obtained in both the coronary face and in the lateral face. The data TR, D1 and D2 presented normal distribution and were statistically analyzed by paired t-test. Statistically significant differences were found in the mesial root trunk region (TR) of both premolars. The mean of the measurements was greater than the distal. Mean and standard deviation were obtained, and both Gracey and Mini Gracey showed mean measurements compatible with the closer furcation entrance (D1 - 1 mm). Goldman Fox 4 showed adaptation only in the mesial face, and Padua Lima showed no access to any of the faces. Thereby it is concluded that the access of the furcation is narrow (D1). The mesial face of the root trunk (TR) showed mean measurement greater than distal face. Gracey and Mini Gracey curettes demonstrated to be compatible for both faces, mesial and distal of the first maxillary premolars studied.

Human dental enamel and dentin structural effects after Er:yag laser irradiation

Ideally projected to be applied on soft tissues, infrared lasers were improved by restorative dentistry to be used in hard dental tissues cavity preparations-namely enamel and dentin. This paper evidentiates the relevant aspects of infrared Erbium laser's action mechanism and its effects, and characterizes the different effects deriving from the laser's beams emission. The criteria for use and selection of optimal parameters for the correct application of laser systems and infuence of supporting factors on the process, such as water amount and its presence in the ablation process, protection exerted by the plasma shielding and structural factors, which are indispensable in dental tissues cavity preparation related to restorative technique, are subordinated to optical modifcations caused by the interaction of the energy dissipated by these laser light emission systems in the targeted tissue substrate. Clinical relevance: Differences in the action of infrared Erbium laser system in regard to the nature of the ablation process and variations on the morphological aspects observed in the super-fcial structure of the target tissue irradiated, may be correlated to the structural optical modifcations of the substrate produced by an interaction of the energy propagated by laser systems.
