1. Hairy Tongue: Differential Diagnosis by Use of Widefield Optical Fluorescence
Resumo A língua pilosa é uma patologia benigna, caracterizada clinicamente por placas hiperqueratinizadas na face dorsal da língua, semelhante a pelos, cuja coloração varia de despigmentada, esbranquiçada, amarelada, verde, acastanhada a preta. O diagnóstico é clínico, e em casos de placas esbranquiçadas, pode ser difícil diferenciar entre leucopl

2. Gestão do Conhecimento e World Class Manufacturing: uma aproximação inicial a partir da revisão de literatura
RESUMO Este artigo apresenta resultado parcial de pesquisa em andamento sobre a proposta de uma metodologia para a integração entre a Gestão do Conhecimento (GC) e o World Class Manufacturing (WCM). A investigação inicial de natureza teórico-conceitual visa desenvolver uma visão abrangente e atual sobre a GC, o WCM, e como (ou “se”) esses construt

3. Characterisation and microleakage of a new hydrophilic fissure sealant - UltraSeal XT® hydro™
ABSTRACT Objectives The aim of this study was to characterise the new hydrophilic fissure sealant, UltraSeal XT® hydro™ (Ultradent Products, USA), and to investigate its in vitro resistance to microleakage after placement on conventionally acid etched and sequentially lased and acid etched molars. Material and Methods The sealant was characterised by

4. Pulsed ultrasound therapy accelerates the recovery of skeletal muscle damage induced by Bothrops jararacussu venom
We studied the effect of pulsed ultrasound therapy (UST) and antibothropic polyvalent antivenom (PAV) on the regeneration of mouse extensor digitorum longus muscle following damage by Bothrops jararacussu venom. Animals (Swiss male and female mice weighing 25.0 ± 5.0 g; 5 animals per group) received a perimuscular injection of venom (1 mg/kg) and treatment

5. Avaliação da viabilidade da quimiluminescência como fonte de luz em terapia fotodinâmica para controle microbiano. / Evaluation of the viability of the chemiluminescence as a PDT light source for microbial control
A terapia fotodinâmica é a combinação do agente fotossensibilizador, da fonte de luz e do oxigênio que pode resultar na oxidação de biomoléculas e gerar danos celulares. Esta técnica é aplicada em diversas situações, desde o controle microbiológico até o tratamento de câncer. A maioria dos estudos utiliza as fontes de luz tradicionais, ou seja

6. Avaliação dos efeitos promovidos pela radiação azul na remineralização do esmalte dentário in vitro / EFFECTS OF BLUE LIGHT IRRADIATION ON DENTAL ENAMEL REMINERALIZATION IN VITRO
This study aimed to investigate the effects of blue radiation on dental enamel remineralization. In addition, a methodology of analysis was developed to evaluate alterations of enamel mineral content by optical coherence tomography. Artificial lesions were formed in bovine dental enamel slabs by immersing the samples in undersaturated acetate buffer (2 mL/mm

7. Avaliação da microdureza e desgaste por escovação simulada de uma resina composta, em função de diferentes fontes de luz e energias de ativação / Influence of different light sources and energy densities on a resin composite microhardness and wear resistance after simulated toothbrushing abrasion test
This in vitro study evaluated comparatively, the superficial microhardness and wear of a resin composite, FiltekTM Z-250 (3M/ESPE) under the influence of different light sources (LED Ultrablue IS/DMC, LED Ultralume 5/Ultradent and halogen VIP/BISCO); with power (300, 600 and above 800mW/cm2) and energy density (6, >8, 12, >16, 24, >32J/cm2) variations.

8. Chaves optoeletronicas de alta tensão a semicondutor
In this work we have studied a semiconductor optoelectronic device to switch high-voltage electrical pulses ( >500 V). The semiconductors used were semi-isolant GaAs and InP that show high-resistivity (>107 W.cm) To switch activation we have built a nitrogen laser that gives pulses of 337.1 nm radiation and duration of 2 ns. We have studied the effects of la

9. Nanoshell-mediated near-infrared thermal therapy of tumors under magnetic resonance guidance
Metal nanoshells are a class of nanoparticles with tunable optical resonances. In this article, an application of this technology to thermal ablative therapy for cancer is described. By tuning the nanoshells to strongly absorb light in the near infrared, where optical transmission through tissue is optimal, a distribution of nanoshells at depth in tissue can

10. In vitro studies of interaction of rickettsia and macrophages: effect of ultraviolet light on Coxiella burnetii inactivation and macrophage enzymes.
The inactivation of Coxiella burnetii in suspension or in cultures of guinea pig peritoneal macrophages by ultraviolet (UV) light was studied. The effect of UV treatment on the activity of macrophage organelle marker enzymes and their subsequent equilibration in linear sucrose gradients was also determined. It was shown that UV treatment of 600 mu W/cm2 for

11. Regular multicharged transient soft matter in Coulomb explosion of heteroclusters
Nanointerfaces of mobile, thin spherical shells of light ions that expand on the femtosecond time scale, can be produced by Coulomb explosion of extremely ionized molecular heteroclusters consisting of light and heavy ions, e.g., (D+Iq+)n (q = 7-35), which are generated in ultraintense laser fields (intensity, I, = 1016 to 1020 W·cm-2).

12. Bacterial Stress Responses to 1-Megahertz Pulsed Ultrasound in the Presence of Microbubbles
Members of a panel of stress-responsive biosensors have been used to study the effect of megahertz frequency ultrasound on Escherichia coli. Insonification causes acoustic cavitation, the collapse of oscillating microbubbles in solution, which can damage bacterial cells. A focused 1-MHz ultrasound transducer, capable of generating a spatial peak pulse averag
