1. A randomized clinical trial on the sealing of occlusal carious lesions: 3–4-year results
Abstract This randomized clinical trial aimed to assess the efficacy of sealing occlusal carious lesions in permanent teeth. The sample consisted of 54 occlusal carious lesions in permanent molars and premolars of 49 patients aged 8–43 years (median: 19 years). The inclusion criteria comprised the presence of a cavity with no access allowing biofilm contro

2. Effects of lactose-containing stevioside sweeteners on dental biofilm acidogenicity
The aim of this study was to evaluate the effect of a commercial lactose-containing stevioside sweetener on biofilm acidogenicity in vivo. Nine volunteers refrained from brushing their teeth for 3 days in five phases. On the 4th day of each phase, the pH of the biofilm was measured by the “Strip method”. Interproximal plaque pH was measured before and up

3. PREPARAÇÃO, CARACTERIZAÇÃO E ESTUDOS ELETROQUÍMICOS DE ELETRODOS MODIFICADOS COM DIFERENTES MONOCAMADAS AUTOORGANIZADAS
In this work were studied investigated different types of modifiers for the formation of self-assembled monolayers on the gold surface. The monolayers used were formed by different structural arrangements, alkyl chains and functional groups. The thiols groups used were: 3-mercaptopropionic acid (MPA), thiolactic acid (TLA), cystamine (CYS) and 11-mercaptound

4. A eletroforese capilar para a separação das metalotioneínas da cianobactéria (Synechococcus PCC 7942) e de mamíferos / Capillary electrophoresis for the separation of cyanobacterial metallothionein (Synechococcus PCC 7942) and mammals
Metallothioneins (MTs) are low molecular weight proteins, which main functions are the regulation of metals levels in the body and detoxification. The capillary electrophoresis (CE) characterization of MT from Synechococcus cyanobacteria was attained by comparison with commercial standards of horse kidney and rabbit liver MTs. The influence of electrolyte, s

5. Sistema para detecção e notificação de problema com DNS reverso / System for detection and notification of problem with reverse DNS
O propósito desse trabalho é sugerir um modelo de ferramenta, que identifica e, opcionalmente, avisa o administrador do domínio remoto sobre, o problema na configuração de DNS reverso, o qual é um dos maiores responsáveis pela ocorrência de falsos positivos nos sistemas de anti-spam. Dessa forma, foram disponibilizados, no capítulo 2, conceitos que

7. Purinergic central pathways involved in the muscle blood flow regulation during alerting defense behaviours. / Vias centrais purinérgicas envolvidas na regulação do fluxo sangüíneo muscular durante os comportamentos de alerta e defesa
The electrical stimulation (ES) of the hypothalamus in the rat produces a well- defined pattern of cardiovascular adjustments including hypertension, tachycardia and skeletal muscle vasodilation. These hemodynamic responses can also be observed in natural conditions during fight and/or flight behaviors. However the neural pathways and possible neurotransmitt

9. Contribuição ao estudo da deposição fotoeletroquimica de cobre silicio-p
: In this work a selective photoelectrochemical copper deposition was developed. The copper thin films was photodeposited from a standard aqueous plating solutions on p-Si. Copper is a promising candidate for use in electronic packaging and ultra-Iarge scale integrated (ULSI) devices due to its low resistivity. However, the thin film morphology is a very imp

10. ClpX protein of Escherichia coli activates bacteriophage Mu transposase in the strand transfer complex for initiation of Mu DNA synthesis.
During transposition bacteriophage Mu transposase (MuA) catalyzes the transfer of a DNA strand at each Mu end to target DNA and then remains tightly bound to the Mu ends. Initiation of Mu DNA replication on the resulting strand transfer complex (STC1) requires specific host replication proteins and host factors from two partially purified enzyme fractions de

11. The wing of the enhancer-binding domain of Mu phage transposase is flexible and is essential for efficient transposition.
A tetramer of the Mu transposase (MuA) pairs the recombination sites, cleaves the donor DNA, and joins these ends to a target DNA by strand transfer. Juxtaposition of the recombination sites is accomplished by the assembly of a stable synaptic complex of MuA protein and Mu DNA. This initial critical step is facilitated by the transient binding of the N-termi

12. Cloning of the Mutator Transposable Element Mua2, a Putative Regulator of Somatic Mutability of the A1-Mum2 Allele in Maize
The identification of the autonomous or transposase-encoding element of the Mutator (Mu) transposable element system of maize is necessary to the characterization of the system. We reported previously that a transcript homologous to the internal region of the MuA element is associated with activity of the Mutator system. We describe here the cloning of anoth
