Cross-sectional difference in BMI between senior and junior students predicts prospective change in BMI at the school level

Poster Presentation: abstract no. 1196The Conference abstracts's website is located at http://www2.kenes.com/apccn/scientific/Pages/ListofAbstracts.aspxOBJECTIVES: To examine whether cross-sectional BMI difference between senior and junior secondary school students was correlated with prospective changes in BMI at the school level. BACKGROUND: Schools are known to exert prospective influences on adolescent BMI. The school effects may also be reflected in cross-sectional BMI differences between senior and junior students in each school. Schools could quickly be identified for weight-control interventions if such cross-sectional differences could predict prospective changes in BMI. METHODS: In the Hong Kong Student …postprin

Exposure to particulate air pollution at different living locations and respiratory symptoms in Hong Kong-an application of satellite information

Respiratory ill-health effects due to particulate air exposure at different geographical locations in Hong Kong that aggregate individual living locations were estimated based on satellite information. We assessed the presence of respiratory symptoms of a frequent cough or sputum in school students aged 11-20 years old (n=9,881). Daily particulate air pollution levels at students' living locations were derived from the surface extinction coefficients measured by satellite and measurements from the air pollutant monitoring stations at ground level. Adjusted odds ratio (OR) [95% CI] of respiratory symptoms was 1.047 [1.005, 1.091] per 10 g m-3 increase in PM10 concentration. Specificity tests showed that adjusted OR of having other symptoms is not significant (p=0.20-0.94). Exposures to PM10 at different geographical locations is associated with increased odds of having respiratory symptoms (cough or sputum) but not with other symptoms unrelated to air pollution. © 2010 Taylor & Francis.postprin

Contributos do Ensino - Aprendizagem do Inglês, nos 3º e 4º anos do Ensino Básico, para os resultados obtidos pelos alunos na disciplina de Inglês, no 5º ano do Ensino Básico, no distrito de Évora.

O presente artigo dá conta da investigação que verificou a relação entre a frequência da Atividade de Enriquecimento Curricular (AEC) de Inglês, pelos alunos dos 3º e 4º anos do Ensino Básico, dos agrupamentos de escolas do distrito de Évora, no biénio 2005-2007 e os resultados obtidos, pelos mesmos, no final do ano letivo 2007/2008, na disciplina de Inglês, no 5º ano do Ensino Básico, nos agrupamentos de escolas do distrito de Évora que frequentaram. Dá, ainda, conta das relações entre esses resultados, a assiduidade, as retenções, o desenvolvimento cognitivo e o género desses mesmos alunos, nos resultados observados no referido 5ºAno

Cyclodextrin-PEI-Tat Polymer as a Vector for Plasmid DNA Delivery to Placenta Mesenchymal Stem Cells

This study aims to modify a cyclodextrin-PEI-based polymer, PEI-β-CyD, with the TAT peptide for plasmid DNA delivery to placenta mesenchymal stem cells (PMSCs). By using the disulfide exchange between the SPDP-activated PEI-β-CyD and TAT peptide, the TAT-PEI-β-CyD polymer was fabricated and the success of this was confirmed by the presence of characteristic peaks for PEI (at δ 2.8-3.2 ppm), CyD (at δ 5.2, 3.8-4.0 and 3.4-3. 6 ppm) and TAT (at δ 1.6-1.9 and 6.8-7.2 ppm) in the 1H NMR spectrum of TAT-PEI-β-CyD. The polymer-plasmid-DNA polyplex could condense DNA at an N/P ratio of 7.0-8.0, and form nanoparticles with the size of 150.6±5.6 nm at its optimal N/P ratio (20/1). By examining the transfection efficiency and cytotoxicity of TAT-PEI-β-CyD, conjugation of the TAT peptide onto PEI-β-CyD was demonstrated to improve the transfection efficiency of PEI-β-CyD in PMSCs after 48 and 96 hours of post-transfection incubation. The viability of PEI-β-CyD-treated PMSCs was shown to be over 80% after 5 h of treatment and 24 h of post-treatment incubation. In summary, this study showed that the TAT-PEI-β-CyD polymer as a vector for plasmid DNA delivery to PMSCs and other cells warrants further investigations. © 2011 The Author(s).published_or_final_versionSpringer Open Choice, 21 Feb 201

Split-Drain Magnetic Field-Effect Transistor Channel Charge Trapping and Stress Induced Sensitivity Deterioration

Session EB: Materials for ApplicationsThis paper proposed an analytical model on the deterioration of magnetic sensitivity of sectorial split-drain magnetic field-effect transistors (SD-MAGFETs). The deterioration is governed by the trap fill rate at the channel boundary traps, which is geometric dependent. Experimental results are presented which show good consistency with the analytical derivation. The deterioration is the most severe at a sector angle of 54.6°, which shows a design tradeoff with sensing hysteresis. Design guidelines for sectorial SD-MAGFET to obtain high sensitivity hysteresis and slow sensitivity deterioration are also presented which provide important information for efficient design. © 2013 IEEE.published_or_final_versio
