Presença de detritos na região apical de dentes de cães apos o preparo biomecánico com ou sem o emprego de substância auxiliar cremosa.

The subject of this work is to observe if the employment of a cream (ENDO-PTC) during the root canal preparation contributes or not to the condensation of debris in the apical region. Twenty root canals of dogs teeth were divided into two experimental groups: in the first one, the biomechanical preparation was carried out up to the n. 50 Kerr file by using irrigation and aspiration with sodium hypochlorite. In the second experimental group the canal negotiation was done in the same way but using a cream (ENDO-PTC) with sodium hypochlorite as a lubrication substance. A final irrigation and aspiration with sodium hypochlorite was also done in this group. The animal was killed and the pieces prepared for histological analysis. The histological results show us that the employment of a cream during the negotiation of the root canal contributes to a higher condensation of debris in the apical area.

Emprego da imunofluorescência direta no estudo das alterações de mucosa de palato, compatíveis com candidíase atrófica crônica, em indivíduos portadores de próteses dentárias totais muco-suportadas.

Histopathology by hematoxilin-eosin (HE) and periodic acid Schiff (PAS), concomitant direct immunofluorescence (DI) against total human immunoglobulins and against Candida albicans, was effectuated in 25 persons dentures wearers. In 5 persons without chronic athrofic candidiasis (CAC) clinical signals in the palate the HE showed wise inflammatory elements in the connective tissue and the PAS marked the continuous basal layer, the intra-cellular grains of granular layer and the uniform parakeratin on epithelial surface. In 20 others, with palatal signals of CAC, in the HE was frequent the features encountered in Candida infected and PAS revealed, beside descontinuous lamina basal and epithelial surface covered by tide and discontinuous parakeratin, the presence of round bodies few largers that presents in the granular layer, casually isolated in the medial portion of ret pegs and connective papillae. In the first 5 persons the DI against total human immunoglobulins not showed signals of the humoral immunologic phenomena, the same was valid to others 20 patients with CAC clinical aspects. However the DI with conjugate against C. albicans in the 20 cases with CAC signals revealed suitable aspects of the structures assumed by Candida in tissues. Cultures of samples obtained of the persons with CAC signals was positive in 100% to Candida, 70% presumptively albicans, against 80% of positiviness to generus Candida, 67% presumptively albicans, in the persons without CAC signals.

Emprego do reagente de fenton como agente coagulante na remoção de substâncias húmicas de água por meio da flotação por ar dissolvido e filtração

Fenton 's reagent was used as coagulant agent to treat water with high true color (100 ± 5 HU) caused by the introduction of humic substances extracted from peat, using dissolved air flotation. The pair value of coagulant dosage x coagulation pH was optimized to posterior construction of coagulation diagrams, reaching apparent color removal efficiency slightly superior to 60%. It was tried to simulate a treatment with complete cycle, carrying out an experiment with sand filtration after flotation, obtaining an effluent with excellent quality, presenting remnant apparent color, turbidity and absorbance of 253.7 nm less or equal to 2 HU, 0.40 TU and 0.009 cm -1, respectively, and residual total iron < 0.005 mg/L and DOC < 0.001 mg/L.

O emprego de hormônio luteinizante recombinante associado ao hormônio folículo-estimulante recombinante nos protocolos de estimulação ovariana com antagonista do GnRH

The purpose of this investigation was to verify the efficacy of recombinant LH supplementation for controlled ovarian stimulation in GnRH-antagonist protocol for assisted reproductive technologies cycles. Search strategies included on-line surveys of databases from 1990 to 2006. In this review and meta-analysis, the observed advantages for the LH supplementation protocol were a higher serum estradiol levels on the day of hCG administration and a higher number of mature oocytes. However, there were no differences observed in the total amount of r-FSH administered, days of stimulation, number of oocyte retrieved, the clinical pregnancy rate per oocyte retrieval, the implantation rate and miscarriage rate. This result demonstrates that the association of r-LH with r-FSH may prevent any decrease in estradiol after antagonist administration and a significant higher number of mature oocytes was obtained. Nevertheless, additional randomized controlled trials are needed confirm these observations.

Emprego da sondagem elétrica vertical com o método da eletroresistividade no estudo do lixão de Macapá-Ap

Vertical electrical soundings using eletroresistivity method were carried out in the public waste landfill in Macapá - AP, having as a goal to investigate the geoelectrical and hidrogeologic characteristics of the ground. The results of geophysics interpretation allowed obtaining a model of five geoelectrical layers until the depth of 14,6 m. This model is correlated to a sedimentary sequence of clay-silt-sandy with laterite. The main flow of the water table, also determined, is concordant to the topographical gradient.

Emprego do imageamento elétrico no estudo da contaminação por cemitérios

Due to lack of environmental protection with which the process of burying the corpses was conducted over the decades, many cemeteries have become areas contaminated by organic and inorganic substances and pathogenic microrganisms. This paper presents the results of electrical imaging in delineation of areas potentially contaminated by necrochorume in the municipal cemetery of Vila Rezende, Piracicaba - SP. The results indicate a depth of water table among 3,1 and 5,1 m, with two flow directions, being one to SW and another to SE. So the probable contamination plume, that has the same directions of underground flow, as for the conductive anomalies verified at the geoelectrics sections confirm the suspicions of contamination in the area. The probable plume the SE is prolonged to out of the cemetery. The location of the conductive anomalies and likely contamination plumes demonstrated that the contamination is linked with the depth of water table level and the burial time.
