Here we present the Transcription Factor Encyclopedia (TFe), a new web-based compendium of mini review articles on transcription factors (TFs) that is founded on the principles of open access and collaboration. Our consortium of over 100 researchers has collectively contributed over 130 mini review articles on pertinent human, mouse and rat TFs. Notable features of the TFe website include a high-quality PDF generator and web API for programmatic data retrieval. TFe aims to rapidly educate scientists about the TFs they encounter through the delivery of succinct summaries written and vetted by experts in the field.

In 1939 the total world production of crude chromite was approximately 1,167,000 metric tons; of which the United States produced only 3,672 metric tons and imported over 317,500 metric tons. Imports came mostly from the Philippine Islands, Cuba, South Africa, and Rhodesia.

Energy drinks have become very popular over the past few years with over half the student population in colleges and universities consuming them at least once a month (Malinauskas et al., 2007). It has been reported that the most common reasons why students consume energy drinks are to maintain alertness, reduce symptoms of hangover, increase energy, to help with driving and to prevent sleepiness (Attila and Cakir, 2011; Malinauskas et al., 2007). Previous research has suggested that energy drinks enhance sensorimotor speed, behaviour, and reduce levels of fatigue (Alford et al., 2001; Horne and Reyner, 2001; Howard and Marczinski, 2010; Kennedy and Scholey, 2004; Smit et al., 2004). The two key ingredients found in energy drinks are caffeine and glucose which have been examined together and alone, which have indicated enhanced reaction times, improvement in both verbal memory and sustained attention and more recently there is evidence to show that expectancy may play a key role in predicting intentions of future consumption (Adan and serra-Grabulosa, 2010). According to Kirsch (1997) people have specific expectations when they consume psychoactive substances that trigger physiological and psychological reactions, which tend to be independent of the psychoactive substance ingested. The concept of expectancy effects can be unambiguous especially when the information provided to the participants prior to the experimental study is specific to a possible outcome response. This thesis investigated the extent of expectancy effect on cognition and mood when psychoactive drinks containing caffeine and glucose were consumed in comparison to non-psychoactive drinks. The investigation commenced with examining the independent effects of caffeine and glucose, followed by the combination of caffeine and glucose as an energy drink on mood and cognition. The investigation advanced by comparing drink presentation effects (i.e., consuming the experimental drink from a branded bottle versus from a glass) irrespective of drink content on mood and cognition. Finally, the investigation lead to exploring what factors may predict expectancy effects when participants’ consumed psychoactive drinks among healthy adults. This was done by applying the Theory of Planned Behaviour model (TPB) (Azjen, 1991) to explore the contribution of specific attitudes, subjective norms and perceived behavioural control to the extent of expectancy effects as well as to behavioural intention, with additional variables including; beliefs, habits, past-behaviour, selfidentity. Self-identity representing someone who drinks energy drinks regularly. The level of internal consistency for Cronbach’s alpha was conducted for each variable within the TPB model and for the additional variables included for test reliability. This thesis consisted of four studies, which found that consumption of caffeine and glucose independently and also in combination resulted in psychoactive effects on mood and cognition. Experiment 2 was the only study, which indicated an expectancy effect for immediate verbal recall task and the mood subscale tension. Conversely, for experiment 4 there was a reverse effect found for the immediate verbal recall task. However, there were significant expectancy and psychoactive effects found for mood subscales throughout the four studies. It was also found that the TPB model had two significant variables past-behaviour and self-identity predicted intentions suggesting that participants who regularly consume psychoactive beverages have salient beliefs about consuming psychoactive drinks and the TPB model can be utilised to predict their intentions. Furthermore, the Theory of planned behaviour model found that habit and self-identity significantly predicted participants’ expectancy effects on the vigour. Indicating consumers of energy drinks are familiar with expected outcome response. This model was unsuccessful in predicting expectancy response for cognitive performance. Thus, overall the findings from the four studies indicated that caffeine and glucose have cognitive enhancing properties, which also positively improve mood. However, expectancy effects have been identified for mood only, whereas the overall findings within this thesis were unable to identify significant predictors of expectancy effect and response.

No Brasil as parasitoses intestinais continuam sendo um grave problema de saúde pública, assim como no restante dos países em desenvolvimento. São causadas principalmente pela falta de saneamento básico, precárias condições de sobrevida e outros fatores sociais, econômicos e políticos. A esquistossomose no município de Igreja Nova, Alagoas, incide principalmente em agricultores que trabalham diretamente no cultivo do arroz, pescadores e pessoas que se banham em águas contaminadas. Nesse sentido, este plano de intervenção tem como objetivo realizar ações educativas voltadas para prevenção da esquistossomose no município. Para subsidiar a construção do plano foram utilizadas informações disponíveis na Secretaria Municipal de Saúde de Igreja Nova (relatórios de gestão), informações obtidas dos profissionais de saúde da UBS, além de textos disponíveis na Biblioteca Virtual do Programa Ágora (Núcleo de Educação em Saúde Coletiva, NESCON; Faculdade de Medicina, UFMG). Por sua vez, foram consultados os bancos de dados da Vigilância Epidemiológica do município, utilizando-se os descritores de busca: "Doenças infecciosas e parasitárias"; "Parasitologia humana"; "Bases de parasitologia médica"; "Vigilância epidemiológica e controle da Esquistossomose: normas e instruções" entre outros. A construção da revisão bibliográfica sobre o tema Esquistossomose foi realizada por meio de busca de artigos em periódicos, consultas em livros textos, e publicações disponibilizadas pelo Ministério da Saúde. As atividades serão direcionadas para trabalhadores da agricultura, pescadores e toda a comunidade que de uma forma ou de outra entra em contato com águas estagnadas contaminadas. As ações educativas contarão com reuniões, capacitações e oficinas educativas. Ao se trabalhar com este plano de intervenção focado em educação para saúde devemos pensar nas articulações que deverão ser feitas. Neste caso, além da participação da população, os órgãos responsáveis pela qualidade da água e do ambiente no município, e outros setores deverão ser envolvidos nesta atividade.
