E-sharing: development and use of learning objects repository

— In the new learning environments, built width digital technologies, the need to promote quality of education resources, commonly known as Learning Objects, which can support formal and informal distance learning, emerge as one of the biggest challenge that educational institutions will have to face. Due to the fact that is expensive, the reuse and sharing became very important issue. This article presents a Learning Object Repository which aims to store, to disseminate and maintain accessible Learning Objects.

Terminologia e b-learning; o regresso de Humpty Dumpry

Este estudo tem por objectivo reflectir sobre o papel da Terminologia na organização conceptual e linguística das áreas de especialidade. Defender-se-á que, pela sua natureza hermenêutica, organizadora, harmonizadora e heurística, esta área científica poderá reduzir a complexidade e a fragmentação lexical e conceptual que impera no domínio dos modelos de educação para o Ensino Superior, permitindo ajudar a clarificar a filiação ideológica das várias visões de ensino, levando deste modo a que o debate seja epistemologicamente transparente. Será focado o caso particular do Blended-Learning, enquanto exemplo de um sub-domínio ainda instável, do ponto de vista da sua organização ontológica e da sua materialização linguística e terminológica.

A B-learning strategy for Therapeutics at the Bachelor Level

Background Information:The incorporation of distance learning activities by institutions of higher education is considered an important contribution to create new opportunities for teaching at both, initial and continuing training. In Medicine and Nursing, several papers illustrate the adaptation of technological components and teaching methods are prolific, however, when we look at the Pharmaceutical Education area, the examples are scarce. In that sense this project demonstrates the implementation and assessment of a B-Learning Strategy for Therapeutics using a “case based learning” approach. Setting: Academic Pharmacy Methods:This is an exploratory study involving 2nd year students of the Pharmacy Degree at the School of Allied Health Sciences of Oporto. The study population consists of 61 students, divided in groups of 3-4 elements. The b-learning model was implemented during a time period of 8 weeks. Results:A B-learning environment and digital learning objects were successfully created and implemented. Collaboration and assessment techniques were carefully developed to ensure the active participation and fair assessment of all students. Moodle records show a consistent activity of students during the assignments. E-portfolios were also developed using Wikispaces, which promoted reflective writing and clinical reasoning. Conclusions:Our exploratory study suggests that the “case based learning” method can be successfully combined with the technological components to create and maintain a feasible online learning environment for the teaching of therapeutics.

Novel potentiometric sensors of molecular imprinted polymers for specific binding of chlormequat

Molecularly imprinted polymers (MIP) were used as potentiometric sensors for the selective recognition and determination of chlormequat (CMQ). They were produced after radical polymerization of 4-vinyl pyridine (4-VP) or methacrylic acid (MAA) monomers in the presence of a cross-linker. CMQwas used as template. Similar nonimprinted (NI) polymers (NIP) were produced by removing the template from reaction media. The effect of kind and amount of MIP or NIP sensors on the potentiometric behavior was investigated. Main analytical features were evaluated in steady and flow modes of operation. The sensor MIP/4-VP exhibited the best performance, presenting fast near-Nernstian response for CMQover the concentration range 6.2×10-6 – 1.0×10-2 mol L-1 with detection limits of 4.1×10-6 mol L-1. The sensor was independent from the pH of test solutions in the range 5 – 10. Potentiometric selectivity coefficients of the proposed sensors were evaluated over several inorganic and organic cations. Results pointed out a good selectivity to CMQ. The sensor was applied to the potentiometric determination of CMQin commercial phytopharmaceuticals and spiked water samples. Recoveries ranged 96 to 108.5%.

Cholesterol 24S-Hydroxylase overexpression inhibits the liver X receptor (LXR) pathway by activating small guanosine triphosphate-binding proteins (sGTPases) in neuronal cells

The neuronal-specific cholesterol 24S-hydroxylase (CYP46A1) is important for brain cholesterol elimination. Cyp46a1 null mice exhibit severe deficiencies in learning and hippocampal long-term potentiation, suggested to be caused by a decrease in isoprenoid intermediates of the mevalonate pathway. Conversely, transgenic mice overexpressing CYP46A1 show an improved cognitive function. These results raised the question of whether CYP46A1 expression can modulate the activity of proteins that are crucial for neuronal function, namely of isoprenylated small guanosine triphosphate-binding proteins (sGTPases). Our results show that CYP46A1 overexpression in SH-SY5Y neuroblastoma cells and in primary cultures of rat cortical neurons leads to an increase in 3-hydroxy-3-methyl-glutaryl-CoA reductase activity and to an overall increase in membrane levels of RhoA, Rac1, Cdc42 and Rab8. This increase is accompanied by a specific increase in RhoA activation. Interestingly, treatment with lovastatin or a geranylgeranyltransferase-I inhibitor abolished the CYP46A1 effect. The CYP46A1-mediated increase in sGTPases membrane abundance was confirmed in vivo, in membrane fractions obtained from transgenic mice overexpressing this enzyme. Moreover, CYP46A1 overexpression leads to a decrease in the liver X receptor (LXR) transcriptional activity and in the mRNA levels of ATP-binding cassette transporter 1, sub-family A, member 1 and apolipoprotein E. This effect was abolished by inhibition of prenylation or by co-transfection of a RhoA dominant-negative mutant. Our results suggest a novel regulatory axis in neurons; under conditions of membrane cholesterol reduction by increased CYP46A1 expression, neurons increase isoprenoid synthesis and sGTPase prenylation. This leads to a reduction in LXR activity, and consequently to a decrease in the expression of LXR target genes.

Mercury, cadmium, lead and arsenic levels in three pelagic fish species from the Atlantic Ocean: intra- and inter-specific variability and human health risks for consumption

Three commonly consumed and commercially valuable fish species (sardine, chub and horse mackerel) were collected from the Northeast and Eastern Central Atlantic Ocean in Portuguese waters during one year. Mercury, cadmium, lead and arsenic amounts were determined in muscles using graphite furnace and cold vapour atomic absorption spectrometry. Maximum mean levels of mercury (0.1715 ± 0.0857 mg/kg, ww) and arsenic (1.139 ± 0.350 mg/kg, ww) were detected in horse mackerel. The higher mean amounts of cadmium (0.0084 ± 0.0036 mg/kg, ww) and lead (0.0379 ± 0.0303 mg/kg, ww) were determined in chub mackerel and in sardine, respectively. Intra- and inter-specific variability of metals bioaccumulation was statistically assessed and species and length revealed to be the major influencing biometric factors, in particular for mercury and arsenic. Muscles present metal concentrations below the tolerable limits considered by European Commission Regulation and Food and Agriculture Organization of the United Nations/World Health Organization (FAO/WHO). However, estimation of non-carcinogenic and carcinogenic health risks by the target hazard quotient and target carcinogenic risk, established by the US Environmental Protection Agency, suggests that these species must be eaten in moderation due to possible hazard and carcinogenic risks derived from arsenic (in all analyzed species) and mercury ingestion (in horse and chub mackerel species).

Relatório de estágio: mestrado em ensino da música

Resumo I - O projecto “Piano e outros Instrumentos/orquestra” consiste na implementação do formato Piano e Orquestra em complemento às aulas individuais e aos ensaios de conjunto. O trabalho foi dirigido a um grupo de três alunos com idades de 9, 12 e 16 anos, do curso de Iniciação, Básico e Secundário da EMNSC (Escola de Música de Nossa Senhora do Cabo). Foram criados momentos distintos em cada fase. Estimulou-se o desenvolvimento de competências musicais e de estratégias metacognitivas visando a evolução dos alunos e a eficácia na realização do estudo individual. O Projecto foi criado com o objectivo de desenvolver as competências musicais, a motivação para realização do estudo individual e de grupo, o espírito e a audição crítica, o controlo dos factores psicológicos, a ansiedade, o aumento da autoconfiança, a aprendizagem, a melhoria da atitude positiva no momento da execução pública e o incremento do interesse pelas actividades relacionadas com a prática musical. A realização deste projecto visou analisar o grau de motivação, o desenvolvimento e a aquisição de competências musicais dos alunos de piano que frequentaram semanalmente aulas individuais, aulas extra de preparação, ensaios com Orquestra “Da Capo”, ensaios com a Orquestra Maior, duos com violoncelo e com canto. Um dos objectivos era comparar o grau de motivação e desenvolvimento dos alunos quando estudam obras nas aulas individuais que constituem o programa curricular e, por outro lado, quando o fazem em peças seleccionadas especificamente para este Projecto. Esta experiência visou proporcionar um conhecimento nos diversos domínios da música, uma visão diferente da funcionalidade do piano em conjunto com os outros instrumentos, a descoberta das sonoridades do piano contrastante e ao mesmo tempo, integrante com outros instrumentos, as formas de funcionamento dos instrumentos de corda, de sopro, dos assuntos relacionados com a afinação e pretendendo-se assim apurar o sentido de fazer parte integrante de um todo.
