25. The influence of non-steroidal anti-inflammatory drugs and paracetamol used for pain control of orthodontic tooth movement: a systematic review
ABSTRACT The present study aimed to perform a systematic literature review to determine if there is a non-steroidal anti-inflammatory drug (NSAID) that interferes less within tooth movement. This research was performed according to the PRISMA statement. Articles were searched in eight electronic databases (PubMed, Scopus, Embase, Web of Science, LILACS, SciE

26. Translation and validation of the Mind-Wandering Test for Spanish adolescents
Abstract Background Working memory capacity and fluent intelligence influence cognitive capacity as a predictive value of success. In line with this, one matter appears, that of mind wandering, which partly explains the variability in the results obtained from the subjects who do these tests. A recently developed measure to evaluate this phenomenon is the

27. Soil pretreatment and fast cell lysis for direct polymerase chain reaction from forest soils for terminal restriction fragment length polymorphism analysis of fungal communities
Abstract Humic substances in soil DNA samples can influence the assessment of microbial diversity and community composition. Using multiple steps during or after cell lysis adds expenses, is time-consuming, and causes DNA loss. A pretreatment of soil samples and a single step DNA extraction may improve experimental results. In order to optimize a protocol fo

28. Factors that alter the biochemical biomarkers of environmental contamination in Chironomus sancticaroli (Diptera, Chironomidae)
ABSTRACT Changes in physiology of the nervous system and metabolism can be detected through the activity of acetylcholinesterase (AChE), alpha esterase (EST-a) and beta esterase (EST-ß) in chironomids exposed to pollutants. However, to understand the real effect of xenobiotics on organisms, it is important to investigate how certain factors can interfere wi

29. Development of Sliding Connections for Structural Analysis by a Total Lagrangian FEM Formulation
Abstract In this study a total lagrangian 2D finite element formulation is used to model plane frames developing large displacements and rotations considering sliding connections. This kind of connections is usually called prismatic and cylindrical joints. In order to be self-containing, the steps of the development of a frame finite element of any approxima

30. Cheese yield in Brazil: state of the art
Abstract This literature review discusses the concepts and factors that influence industrial cheese yield and compiles the latest studies conducted in Brazil involving this theme. In seeking to support managerial decision-making, cheese yield can be measured at the end of processing or estimated prior to this. In research and industry, measuring and estimati

31. Entendendo o processo químico de bioativação da sinvastatina por métodos experimentais e computacionais: uma aula prática
Cholesterol is a lipid which in high concentration can be an important risk factor for coronary diseases and atherosclerotic lesions. This lipid presents an endogenous biosynthesis that involves several steps; one of them is modulated by the enzyme 3-hydroxy-3-methylglutaryl coenzyme A reductase (HMG-CoA reductase). HMG-CoA reductase is inhibited by statins,

32. Formation of Aluminum Titanate with Small Additions of MgO and SiO2
The formation of aluminum titanate was investigated by isothermal treatments of samples obtained from equimolar mixtures of alumina and titania, containing small amounts of silica and magnesia. Results of differential thermal analysis and Rietveld refinements of data collected by X-ray powder diffraction (XRPD) showed that additions of silica in amounts used

33. ESTUDO DA GLICOSILAÇÃO DO CICLO-HEXANOL COM DIFERENTES DERIVADOS DE D-GLICOSAMINA E PROMOTORES DE GLICOSILAÇÃO PELO MÉTODO DE KOENIGS-KNORR
We report herein a study on the glycosylation of cyclohexanol with four D-glucosamine-based peracetylated glycosyl chlorides bearing different substituents at C-2 and three glycosylation promoters, silver carbonate, silver triflate and mercury II chloride/mercury II oxide, by the Koenigs-Knorr method. Under the conditions studied, glycosylation was successfu

34. Influence of the Lipid Phase Removal on the Quantification of Cu, Fe and Zn Bound to Proteins from Golden Flaxseed (
Linum usitatissimum L .)The analysis of metals bound to proteins requires careful sample preparation. Experimental procedures involved in this area should be developed aiming to retain the metal species bound to the protein structure. Some pre-fractionation steps are commonly used and in many cases it is necessary to disrupt the lipid-protein interaction by performing lipid remo

35. The influence of Brazilian plant extracts on Streptococcus mutans biofilm
Nineteen plant extracts obtained from plants from the Brazilian Amazon showed activity against planktonic Streptococcus mutans, an important bacterium involved in the first steps of biofilm formation and the subsequent initiation of several oral diseases. Objective: Our goal was to verify whether plant extracts that showed activity against planktonic S. mut

36. Otimização e validação da extração sólido-líquido e purificação em baixa temperatura de HPAs em lodo de esgoto
In this study, a method of solid-liquid extraction and purification at low temperature (SLE-PLT) to determine 16 polycyclic aromatic hydrocarbons (PAHs) in sewage sludge was optimized and validated. The analyses were performed by HPLC-UV. The extraction phase, homogenization procedure, influence of pH, ionic strength and clean-up of the extracts were optimiz
