1. A Selective Gas Chromatography-Selected Ion Monitoring Mass Spectrometry (GC-MS/SIM) Method to Determine Polychlorinated Biphenyls in Fuller’s Earth
Polychlorinated biphenyls (PCBs) are carcinogenic to humans and can be found in Fuller’s earth used for the regeneration of used transformer oil. This work describes a highly selective gas chromatographic-selected ion monitoring mass spectrometric method (GC-MS/SIM) for the simultaneous determination of three Aroclor PCB congener mixtures (1242, 1254, and

3. Influence of the oxidation step on the behaviour and the performances of an oxygen carrier in fixed bed reactor
Chemical Looping Combustion is a promising technology for clean power generation with integrated CO2 capture. In this process the oxygen required for combustion is provided by a metal oxide. This work deals with the development of an experimental procedure to study performances of an oxygen carrier during oxidation/reduction cycles and the influence of the o

4. Terapia laser de baixa intensidade a 808 nm reduz a resposta inflamatória e favorece a regeneração muscular
Muscle regeneration is a complex phenomenon, involving coordinated activation of several cellular responses. During this process, oxidative stress, and consequent tissue damage occur with a severity that may depend on the intensity and duration of the inflammatory response. Among the therapeutic approaches to attenuate inflammation and increase tissue repair

6. Vein graft fulfilled with fat in peripheral nerve repair: a new proposal / Enxerto venoso preenchido com gordura no reparo de nervo periférico: uma nova proposta
With technology advance and the resultant production of more sophisticated equipment, microsurgery has been obtaining more attention in the experimental investigation field referred to peripheral nerves repair. It is know that in case of simple nerve section, without tissue loss, the end-to-side-neurorraphy is the most recommended technique. However, in each

7. Análise de células t regulatórias foxp3+no líquen plano oral
T regulatory cells have the function of controlling immune responses and maintaining self-tolerance. The FoxP3 has been considered the most specific marker for Treg cells. The aiming of this paper was to evaluate the immunoexpression of FoxP3 in the inflammatory infiltrate from oral lichen planus (OLP) and to compare it with the infiltrate in fibrous inflamm

8. The effects of low power laser irradiation on the regeneration of the common fibular nerve in rat submitted to a crush lesion. / Os efeitos da irradiação com laser de baixa potência na regeneração do nervo fibular comum do rato submetido a lesão por esmagamento
Peripheral nerve regeneration is a natural process, which requires a long period to complete, with a few evidences that physical agents including laser, can speed it up. The main objective of this investigation was to analyze the influence of low power laser (AsGaAL) irradiation on nerve regeneration, in a model of crush injury of the common fibular nerve of

9. Mophologic and biochemical evaluation from articular disk of rat s TMJ submitted to low power laser therapy : experimental studies in bearer animals of tempromandibular joint disfunction / Avaliação morfologica e bioquimica do disco articular da ATM de ratos submetidos a terapia com laser de baixa potencia : estudo experimental em animais portadores de disfuncão temporomandibular
Disorders resulting from injury or disease related to TMJ affect the masticatory apparatus as a whole and are characterized as temporomandibular joint disorder (TMJD). It is known that about seven percent of world population requires treatment for the TMJD. Cartilaginous tissues, such as those that constitute the articular disc of the ATM, have a limited cap

10. Study of behavior of copper in systhetic rainwater of São Paulo and Rio de Janeiro and its protection against corrosion by coating and patino exposed to climate action. / Estudo do comportamento de cobre em águas de chuva sintéticas de São Paulo e Rio de Janeiro e sua proteção contra corrosão por revestimentos e pátinas expostos à ação climática.
Copper is one of the metals most widely used to produce metallic artifacts of the artistic and cultural heritage. This is partially due to its great ability to combine with other compounds, forming patinas of different colors. Many of such artifacts are permanently exposed to open air, being thus subjected to the action of atmospheric agents such as rain and

11. Efeito da fototerapia com laser de baixa potência no remodelamento dos colágenos i e iii no processo de regeneração do músculo esquelético de rato. / Effect of the fototerapia with laser of low power in the remodelamento of colágenos i and III in the process of regeneration of the esquelético muscle of rat.
A fototerapia com laser de baixa potência (LBP) tem sido utilizada para estimular a reparação tecidual em diferentes tecidos. Entretanto, seu papel no remodelamento muscular, especialmente sua ação no componente colagênico da matriz extracelular, ainda não está bem esclarecido. O objetivo do presente estudo foi investigar o efeito do laser no remodel

12. Avaliação da regeneração óssea, sob a influência do laser de baixa intensidade, na região da sutura palatina de ratos após expansão da maxila / Evaluation of osseous regeneration, using the low-power laserterapy in the midpalatal suture in rats after maxillary expansion
Rapid maxillary expansion is one of the therapy used in the practice orthodontic to the posterior crossbite correction. Relapsed after expansion treatment required a contention device to guarantee a success therapy. The neoformation suture and the maxilla have maintained in the new position for a period to get the stability. To accelerate the osseous regener
