Estudo da assimetria da fossa mandibular, em crânios secos de crianças pelo método radiográfico

The Temporomandibular Joint is a noble structure of the complex mandibular, a lot of research was conducted on the to signs and symptoms of the alterations that attack those structures. ln spite of the high incidence of the DTM in children, there's little knowledge about it, wich makes difficult the treatment Desorders Craniomandibulares (DCM) or Desorders Temporomandibulars (DTM). The Temporomandibular Joint is composed basically by three elements: bones, muscles and disk, in relation to bony part, we have the fossae mandibular that is part of the temporary bone and wich houses the condyle mandibular, accomplishing the articulation among the cranium and the jaw (it leaves piece of furniture of the articulation). Our intention in that work was of verifying a possible asymmetry of the fossae mandibular on the left side and of the right side in relation to two straight line: a straight line that coincided with the plane medium sagittal and another perpendicular straight line to the plan medium sagittal. Analyzing, the fossae mandibular in 91 dry craniums of children, with age varying between four months of life intrauterina and five years, in x-rays in that the incidence was cranium-flow, we could end that: in spite of we find statistical significance in relation to that asymmetry, clinic cannot affirm that interferences on occlusion exists for that asymmetry

Pré tratamento dentinário influência do condicionamento ácido, irradiação laser e hipermineralização na resistência ao cisalhamento de sistema adesivo multi uso

The disadvantages generated by the acid etching of the dentin, such as an increase in its permeability, in the surface moisture and in the potential to denature the external dentinal collagen, the formation of a fragility zone and the citotoxicity of the adhesive monomers; which are all aggravated by the depth of the dentin, have stimulated new and different treatment philosophies of the dentin. The purpose of the present study, therefore, was to investigate the effects of three dentin treatments: laser irradiation, acid etching and hypermineralization, in the shear bond strength of the SMP Plus bonding system. Sixty bovine incisors were extracted and randomly selected immediatly alter the animal's death. They were kept frozen (-18°C) for no longer than 14 days. After buccal dentinal surface had been exposed, X-Rays were taken to control the dentin thickness. The specimens were separated into two groups: (1) Control, kept in distilled water at 4ºC; (2) Mineralized, kept in hypermineralized solution at 4°C for 14 days. Each group was divided into three sub-groups according to the type of dentin treatment used: group F - followed the manufacturer instructions (acid-etching + primer + bond), group AL (acid-etching + primer + bond + laser) and group LA (laser + (laser + acid-etching + primer + bond). A composite resin standard cylinder (Z100-3M) was bond to the dentinal surface and the shear bond strength performed on a Universal lnstron machine 4301, with 500 Kg load and at 0,5mm/min. speed. The analysis of variance (ANOVA) determined that the treatments influenced the shear bond strength values (p<0,05) with the following average shearing load at failure: AL (9,96 MPa), F (7,28MPa) e LA (4,87 MPa). The interaction between the two factors analyzed Group (control and mineralized) and treatment (F, AL, LA) also influenced the shear bond strength (p<0,05). The highest values were obtained...

Uso da radioterapia no tumor venéreo transmissível em cães

Since the discovery of x rays, the use of radiation in oncology has advanced remarkably. In Brazil, radiation therapy in animals is limited to some isolated studies in public universities and the procedures performed is still precarious because radiation equipments are expensive and there is still a lack of skilled professionals. The transmissible venereal tumor (TVT) is a contagious neoplasm of spontaneous occurrence, commonly treated with vincristine. This paper describes the positive experience of radiotherapy as an isolated option or as an combined treatment with vincristine in three cases of TVT. It was observed that radiotherapy may be used in routine clinical chemotherapy alone or combined with chemotherapy since suitable sources of radiation are provided.

Radioterapia em medicina veterinária: princípios e perspectivas

This work presents a brief historical about the use of ionizing radiations in Veterinary Medicine, instructing the physical beginnings and techniques wrapped in the realization of the proceedings of radiotherapy in animals, illustrating some treated cases, highlighting the difficulties and pointing to the perspectives and importance of the acting of the medical physics in this kind of therapeutic still little used in the national scenery.

Perda de carga em reduções concêntricas de PVC

In the pumping pipelines the located load losses are very important since they have direct influence on hydraulic design of an irrigation system, especially regarding the concentric reducers used in the distribution lines. Hence this work was conducted in the Laboratório de Hidráulica do Centro Federal de Educação Tecnológica de Uberaba. We analyzed 03 concentric reducers PVC 75 x 50 mm, 50 mm and 35 x 35 x 1 "operating at different flow rates. The performance of the tests with the variation of flow in every situation possible to obtain equations to estimate the loss. The equation models presented a high setting, thus enabling the determination of the localized head loss in a situation closer to field reality. For the reduction of 75 x 50 x 35 mm and 50 mm at a flow rate 16.97 m³ h-1 the pressure drop reduction was obtained respectively 0.9263 and 2.7408 mca. To the reduction of 35 x 1 "at a flow rate of 6.02 m³ h-1 was obtained 2.9304 mca pressure drop reduction. The located losses produced by these reductions are relatively high and should be considered with great discretion in hydraulic design of the irrigation system.

Efeito de fungos contaminantes na produtividade de dois isolados de Agaricus blazei em duas formulações de composto

The effect of the contaminant fungi Trichoderma sp. and Chaetomium olivacearum on the cultivation of the ABL 99/30 and ABL 04/49 isolates of A. blazei in two compost formulations made up with tyfton (Cynodom dactylon) and oat (Avena sativa) was evaluated. The experimental design was a totally randomized 2 x 2 x 3 factorial design with 6 repetitions. The experimental unit consisted of 12-12.5 kg of wet compost. During the spawning, 150 g of Trichoderma sp. and C. olivacearum were added to the compost. The experiment was carried out in a climatized room, with humidity between 75-90% and temperature of 28º C. The productivity averages of the ABL 99/30 isolate of A. blazei were higher than those of ABL 04/49 and Trichoderma sp. and C. olivacearum negatively influenced the production of A. blazei. The different composts (based on tyfton and oat straw) did not influence the production of basidiomata.
