13. Ca alginate as scaffold for iron oxide nanoparticles synthesis
Recently, nanotechnology has developed to a stage that makes it possible to process magnetic nanoparticles for the site-specific delivery of drugs. To this end, it has been proposed as biomaterial for drug delivery system in which the drug release rates would be activated by a magnetic external stimuli. Alginate has been used extensively in the food, pharmac

14. The effects of variable interval schedule on preference and liquid consumption by rats subjected to chronic mild stress / Efeitos do esquema de intervalo variável na preferência e no consumo de líquidos apresentados por ratos submetidos ao chronic mild stress
The Chronic Mild Stress (CMS) is an experimental animal model of depression induced by the exposure of rats to a set of moderate and uncontrollable aversive stimuli in a long and uninterrupted period of time. The purpose of this study was to investigate the relationship between performance in variable interval schedule of behavior and exposure to the protoco

15. Efeitos de diferentes histórias experimentais sobre o comportamento de seguir regras em participantes classificados de flexíveis e inflexíveis / Effects of diferent experimental histories on the rule-following behavior in participants classified as flexible and unflexible
The present study investigated wether the maintenance or not of the behavior of following discrepant rules of programmed contingencies of reinforcement in an experimental situation depends more on the listeners experimental history or his pre-experimental history, inferred by his answers to a questionnaire about unflexibility. Sixteen college students previo

16. Laboratory and field evaluation of an oviposition trap for Culex quinquefasciatus(Diptera: Culicidae)
An ovitrap (BR-OVT) based on physical and chemical stimuli for attracting gravid Culex quinquefasciatus (Diptera: Culicidae) females was developed and evaluated under laboratory and field conditions. Attractants were assayed using alternative chamber bioassays prior to being used in the BR-OVT oviposition trap. A significant preference of gravid females for

17. Evaluation of desensitizing agents effectiveness in the treatment of dentinal hypersensitivity / AvaliaÃÃo da eficiÃncia de agentes anti-hiperestÃsicos no tratamento da hiperestesia dentinÃria
Dentinal hypersensitivity is a complex sensorial condition which can cause considerable concern in the dental office. Despite the large number of different proposed kinds of treatment, there is no product or therapy reported in literature that could be considered ideal to eliminate this uncomfortable situation. The aim of this study, comprised by two manuscr

18. Variabilidade da atividades cerebral em resposta a estímulos vestibular e ocolomotor avaliada por fMRI / Variability of cerebral activity in response to vestibular and oculomotor stimuli evaluated by fMRI
Assessing inter-variability of functional activations is of practical importance in the use of functional magnetic resonance imaging (fMRI) in clinical context. The main objective of this study is to analyze the variability of cerebral activation of the vestibular and oculomotor systems through an optokinetic horizontal, a pursuit and saccadic eye movement s

19. Identificando comportamentos pré-requisitos para o ensino da adição e da subtração / Identifying prerequisite behaviors to the teaching of addition and subtraction
The educator can carry out the teaching starting by the behaviors already established in the students repertoire, which reminds us the importance of developing instruments to assess this repertoire of the student.. The purpose of the present research was to construct a sequence of prerequisite behaviors to the teaching of addition and subtraction, to constru

20. PRODUCT DEVELOPMENT TO CREDIT CARDS INDUSTRY: A CONJOINT ANALYSIS APPLICATION / DESENVOLVIMENTO DE PRODUTOS PARA A INDÚSTRIA DE CARTÃO DE CRÉDITO: UMA APLICAÇÃO DE ANÁLISE CONJUNTA
The new product development and correct market segmentation are fundamental to define marketing strategy in order to provide a competitive advantage. To do this, the perfect understanding of customer needs is essential, too. In this research, the conjoint analysis theory is used with the objective of showing the group of characteristics understood as desirab

21. Regulação da expressão e ativação do fator de transcrição C-JUN no miocardio de ratos submetido a sobrecarga pressora aguda
The early expression of immediate early genes is a fundamental feature of myocardial hypertrophy. The immediate early gene c-jun codifies a transcription factor that has been assigned to be an important regulator of the hypertrophic response in cardiac myocytes. In the present study we investigated whether pressure overload or phenylephrine treatment stimula

22. Apical localization of K+ channels in taste cells provides the basis for sour taste transduction.
Previous studies have shown that mudpuppy taste receptor cells respond to sour taste stimuli (weak acids) with depolarizing receptor potentials or action potentials that are blocked by the K+ channel blocker tetraethylammonium. Voltage-clamp recordings from isolated taste cells indicated that taste receptor cells exhibit a variety of voltage-dependent conduc

23. Computational subunits of visual cortical neurons revealed by artificial neural networks
A crucial step toward understanding visual processing is to obtain a comprehensive description of the relationship between visual stimuli and neuronal responses. Many neurons in the visual cortex exhibit nonlinear responses, making it difficult to characterize their stimulus–response relationships. Here, we recorded the responses of primary visual cortical

24. Directional tuning interactions between moving oriented and textured stimuli in complex cells of feline striate cortex.
In sixty-five complex cells recorded from striate cortex of lightly anaesthetized, paralysed cats we investigated directional selectivity for motion of oriented and textured stimuli, both alone and when moving simultaneously in the same direction and at the same velocity. Monocular comparisons were made over a range of velocities for the dominant eye in all
