Creating teaching and learning in Europe: promoting a new paradigm

The tides of globalization and the unsteady surges and distortions in the evolution of the European Union are causing identities and cultures to be in a state of flux. Education is used by politicians as a major lever for political and social change through micro-management, but it is a crude tool. There can, however, be opportunities within educational experience for individual learners to gain strong, reflexive, multiple identities and multiple citizenship through the engagement of their creative energies. It has been argued that the twenty-first century needs a new kind of creativity characterized by unselfishness, caring and compassion—still involving monetary wealth, but resulting in a healthy planet and healthy people. Creativity and its economically derived relation, innovation, have become `buzz words' of our times. They are often misconstrued, misunderstood and plainly misused within educational conversations. The small-scale pan-European research study upon which this article is founded discovered that more emphasis needs to be placed on creative leadership, empowering teachers and learners, reducing pupils' fear of school, balancing teaching approaches, and ensuring that the curriculum and assessment are responsive to the needs of individual learners. These factors are key to building strong educational provision that harnesses the creative potential of learners, teachers and other stakeholders, values what it is to be human and creates a foundation upon which to build strong, morally based, consistent, participative democracies.

Selected topics in probiotics and prebiotics: meeting report for the 2004 international scientific association for probiotics and prebiotics

On August 2931, 2004, 84 academic and industry scientists from 16 countries gathered in Copper Mountain, Colorado USA to discuss certain issues at the forefront of the science of probiotics and prebiotics. The format for this invitation only meeting included six featured lectures: engineering human vaginal lactobacilli to express HIV inhibitory molecules (Peter Lee, Stanford University), programming the gut for health (Thaddeus Stappenbeck, Washington University School of Medicine), immune modulation by intestinal helminthes (Joel Weinstock, University of Iowa Hospitals and Clinics), hygiene as a cause of autoimmune disorders (G. A. Rook, University College London), prebiotics and bone health (Connie Weaver, Purdue University) and prebiotics and colorectal cancer risk (Ian Rowland, Northern Ireland Centre for Food and Health). In addition, all participants were included in one of eight discussion groups on the topics of engineered probiotics, host-commensal bacteria communication, 'omics' technologies, hygiene and immune regulation, biomarkers for healthy people, prebiotic and probiotic applications to companion animals, development of a probiotic dossier, and physiological relevance of prebiotic activity. Brief conclusions from these discussion groups are summarized in this paper.

Right hemisphere language functions and schizophrenia: the forgotten hemisphere?

This review highlights the importance of right hemisphere language functions for successful social communication and advances the hypothesis that the core deficit in psychosis is a failure of segregation of right from left hemisphere functions. Lesion studies of stroke patients and dichotic listening and functional imaging studies of healthy people have shown that some language functions are mediated by the right hemisphere rather than the left. These functions include discourse planning/comprehension, understanding humour, sarcasm, metaphors and indirect requests, and the generation/comprehension of emotional prosody. Behavioural evidence indicates that patients with typical schizophrenic illnesses perform poorly on tests of these functions, and aspects of these functions are disturbed in schizo-affective and affective psychoses. The higher order language functions mediated by the right hemisphere are essential to an accurate understanding of someone's communicative intent, and the deficits displayed by patients with schizophrenia may make a significant contribution to their social interaction deficits. We outline a bi-hemispheric theory of the neural basis of language that emphasizes the role of the sapiens-specific cerebral torque in determining the four-chambered nature of the human brain in relation to the origins of language and the symptoms of schizophrenia. Future studies of abnormal lateralization of left hemisphere language functions need to take account of the consequences of a failure of lateralization of language functions to the right as well as the left hemisphere.

Effect of Short-term High-Dose Creatine Supplementation on Measured GFR in a Young Man With a Single Kidney

It currently is unknown whether creatine supplementation is safe for people with or at risk of kidney disease. We report on the short-term effects of creatine supplementation on kidney function in a young man with a single kidney and mildly decreased glomerular filtration rate (GFR). A 20-year-old man who had undergone unilateral nephrectomy and presented with mildly decreased GFR without kidney damage underwent a trial with 35 days of creatine supplementation (20 g/d for 5 days followed by 5 g/d for the next 30 days) and had his kidney function monitored. After the intervention, (51)Cr-EDTA clearance (pre, 81.6 mL/min/1.73 m(2); post, 82.0 mL/min/1.73 m(2)), proteinuria (protein excretion: pre, 130 mg/d; post, 120 mg/d), and electrolyte levels were unchanged. Albuminuria, serum urea level, and estimated creatinine clearance were decreased (pre, 4.6 mg/d; post, 2.9 mg/d; pre, 37 mg/d; post, 28 mg/dL; and pre, 88 mL/min/1.73 m(2); post, 71 mL/min/1.73 m(2), respectively), whereas serum creatinine level was slightly increased (pre, 1.03 mg/dL; post, 1.27 mg/dL), falsely suggesting kidney function impairment. This prospective report suggests that short-term creatine supplementation may not affect kidney function in an individual with a single kidney, mild decreased GFR, and ingesting a high-protein diet (ie, 2.8 g/kg/d). This finding has great relevance considering that creatine-induced kidney disease has been a growing concern, even for healthy people. Am J Kidney Dis 55: e7-e9.

Excreção renal de fósforo em cães nefropatas sob estimulação dopaminérgica

A dopamina possui um amplo espectro de ação no sistema urinário. Aumento da taxa de filtração glomerular, do fluxo sanguíneo renal e da excreção fracionada de sódio e fósforo é um efeito renal esperado em indivíduos normais. Este estudo foi realizado com o propósito de testar a hipótese de que a dopamina é capaz de aumentar a excreção fracionada de fósforo em cães nefropatas. Cinco cães sadios e quatro cães nefropatas, com doença predominantemente túbulo-intersticial, foram submetidos à infusão de solução controle (NaCl 0,9%) e solução de dopamina em duas taxas de infusão diferentes (1µg kg-1 min-1 e 3µg kg-1 min-1), sendo realizadas avaliações antes, durante e 30 minutos após a infusão. Os cães sadios apresentaram aumento significativo (P≤0,05) na excreção fracionada e excreção renal de fósforo durante a infusão de 3µg kg-1 min-1, porém a concentração sérica permaneceu sem alterações durante o tratamento. Já os cães nefropatas apresentaram aumento significativo (P≤0,05) na excreção fracionada e excreção renal de fósforo, tanto na dose de 1µg kg-1 min-1, como na de 3µg kg-1 min-1. Além disso, após a infusão de 1µg kg-1min-1, a concentração sérica de fósforo apresentou redução significativa. Os resultados são indicativos de que a dopamina nas doses de 1µg kg-1 min-1 e 3µg kg-1 min-1 podem ser incluídas na terapia de cães nefropatas para melhorar a homeostase de fosfato.

Toxicogenetic monitoring in urban cities exposed to different airborne contaminants

Microparticles found in the air may be associated with organic matter that contains several compounds, such as Polycyclic Aromatic Hydrocarbons (PAHs) and nitro-PAHs, and may pose a significant risk to human health, possibly leading to DNA mutations and cancers. This study associated genotoxicity assays for evaluating human exposure with the atmospheric air of two urban areas in southern Brazil, that received different atmospheric contributions. Site 1 was under urban-industrial influence and the other was a non-industrial reference, Site 2. Organic extracts from the airborne particulate matter were tested for mutagenicity via the Salmonella/microsome assay and analyzed for PAH composition. Cells samples of people residing in these two cities were evaluated using the comet and micronucleus assay (MN).Concentrations of the individual PAHs ranged from 0.01ng/m3 (benzo[a]anthracene) to 5.08ng/m3 (benzo[ghi]perylene). As to mutagenicity analysis of airborne, Site 1 presented all the mutagenic responses, which varied from 3.2±1.22rev/m3 (TA98 no S9) to 32.6±2.05rev/m3 (TA98, S9), while Site 2 ranged from negative to minimal responses. Site 1 presented a high quantity of nitro and amino derivatives of PAHs, and peaked at 56.0±3.68rev/μg (YG1024 strain). The two groups presented very low DNA damage levels without intergroup difference. Although Site 1 presented high mutagenic responses in the air samples, high PAH levels, healthy people exposed to this environment did not show significative damage in their genetic material. However, the evaluation of different environmental and genetic damage in such population is necessary to monitor possible damages. © 2013 Elsevier Inc.

Influência da facilitação neuromuscular proprioceptiva na alteração da fibra do músculo rectus femoris vista através da eletromiografia de superfície e dinamometria analógica

A Facilitação Neuromuscular Proprioceptiva – FNP – é uma técnica que cada vez mais vem sendo utilizada no treinamento muscular de pessoas saudáveis e atletas. Pesquisas vêm mostrando que exercícios de resistência, dentre eles a FNP, são capazes de converter o tipo das fibras musculares treinadas. Esta pesquisa teve como objetivo verificar a eficiência da FNP no acréscimo de força muscular e verificar por métodos não invasivos se haveria indicativo de conversão de tipo de fibra muscular após o treinamento. Um grupo amostral de 22 jovens, universitárias do sexo feminino com idade entre 18 e 25 anos e fisicamente ativas, foi dividido em: grupo controle (GC n=10) e grupo experimental (GE n=12). Foram inicialmente mensurados: I - força da Contração Voluntária Máxima - CVM do músculo quadríceps por dinamometria analógica e root mean square - RMS e II - área de ativação muscular por eletromiografia de superfície (EMG) de todos os sujeitos. Após a primeira coleta de dados o GE realizou treinamento baseado na FNP no membro inferior dominante por 15 sessões em 5 semanas. Ao final, nova mensuração foi feita em todos. Quanto à força muscular, houve acréscimo em ambos os grupos, significativa no GC (p<0,01) e no GE (p<0,05); para RMS e tempo de CVM, houve aumento não significativo no GE, mas a interação Vxt aumentou significativamente para este grupo. Os resultados corroboram a literatura ao mostrar que músculos com predomínio de fibras resistentes (fibras I/ II A) possuem maior tempo de contração com mais ativação elétrica e de que a FNP é capaz fibras tipo II B para II A. Concluiu-se que para a amostra estudada o treinamento foi eficiente no acréscimo de força muscular e os dados EMG apresentados mostram fortes evidências da conversão das fibras do músculo treinado.
