Oral N-acetylcysteine attenuates the rat pulmonary inflammatory response to antigen.

2003

Oxidative stress is involved in the pathophysiology of inflammatory airway diseases including asthma; therefore, antioxidants might be of clinical benefit in asthma treatment. In the present study, the effects of N-acetylcysteine on sensitised brown Norway rats were examined. N-Acetylcysteine (3 mmol kg body weight(-1) administered orally) was given daily for 1 week before challenge and various antigen-induced pulmonary responses were studied. Antigen exposure increased lipid peroxidation in bronchoalveolar lavage fluid (BALF) and oxidised glutathione levels in lung tissue 2 h after challenge. Lung nuclear transcription factor-KB-binding activity was increased 2 h after challenge, and BALF …

Clinical implications of airway hyper-responsiveness in COPD

2006

COPD represents one of the leading causes of mortality in the general population. This study aimed at evaluating the relationship between airway hyperresponsiveness (AHR) and COPD and its relevance for clinical practice. We performed a MEDLINE search that yielded a total of 1919 articles. Eligible studies were defined as articles that addressed specific aspects of AHR in COPD, such as prevalence, pathogenesis, or prognosis. AHR appears to be present in at least one out of two individuals with COPD. The occurrence of AHR in COPD is influenced by multiple mechanisms, among which impairment of factors that oppose airway narrowing plays an important role. The main determinants of AHR are reduct…

Deep inspiration-induced bronchoprotection is stronger than bronchodilation

2000

We have previously shown that in healthy subjects, deep inspiration (DI) has not only a bronchodilatory but also a bronchoprotective effect that is absent in asthmatic subjects. We conducted the study reported here to test the hypothesis that the bronchoprotective effect is stronger than the bronchodilatory effect, and to determine the extent to which these two effects are related. Ten healthy subjects underwent provocations in which single doses of methacholine, previously shown to reduce FEV(1) by 10% to 20% (Dose 1) and by 20% to 40% (Dose 2) were administered after a 20-min period devoid of DI. To measure the bronchodilator effect, DIs were performed immediately after the first spiromet…

A simple method of bronchoprovocation using a valved holding chamber.

2004

This study was undertaken to ascertain whether the use of a valved holding chamber (VHC) during bronchial provocation testing might increase lung deposition and repeatability of the test relative to the tidal breathing method. The 2-min tidal breathing results were compared to five inhalations from a VHC device in patients using the Pari-provoII nebulizer (MMD = 2.1mkm). Lung and mouth deposition, losses though the exhaled air and losses before aerosol delivery to the patient's mouth were measured in patients using a radiolabeled 99Tc-DTPA solution and gamma camera. The study revealed that lung deposition was 67% with the VHC method, and losses with exhaled air were 29% of the inhaled amoun…

INVESTING IN SKILLS AND INNOVATION – NEW STRATEGIC TASKS FOR PUBLIC ADMINISTRATIONS

2014

Evidence shows that in the labour market the most demanded specialists are those with high-level vocational skills, implying also their competence for innovation. The latest EU policy initiatives explicitly call for innovation in vocational education and training (VET) systems. This is a relatively new VET policy development. At the same time, it is not yet sufficiently discussed how innovation in VET systems could be best translated in practical terms. Traditionally innovation has been related to the research and development domain, and little routine practices exist regarding the VET system. The present paper will explore the opinions and estimations by public administrators and experts r…

Propuesta de indicadores del proceso de enseñanza/aprendizaje en la formación profesional en un contexto de gestión de calidad total

2014

Se propone una batería de indicadores del proceso de enseñanza-aprendizaje diseñados para la práctica cotidiana de la evaluación interna de un centro de formación profesional que permita valorar la eficacia del proceso de E/A y el desarrollo de los factores que influyen en él. Al mismo tiempo, se proponen fórmulas para ajustar algunos indicadores globales que permitan valorar la eficacia del funcionamiento del centro con independencia de los factores externos más relevantes. Los indicadores propuestos pretenden obtener información diferenciada que permita tomar decisiones para mejorar de forma continua el funcionamiento del centro, detectando los factores que actúan como limitantes de los b…

Recurrence Quantification Analysis as a Methodological Innovation for School Improvement Research

2021

Contains fulltext : 240653.pdf (Publisher’s version ) (Closed access) School improvement and educational change can be facilitated by learning through reflection, as this allows teachers to discover ways to develop and adapt to change. Higher levels of engagement in reflection have been found to be beneficial, but it is unclear from which everyday routine in engagement in reflection higher levels arise, and thus whether occasions to make knowledge explicit should be organized with a certain constancy. In this study, we therefore used a conceptualization of teacher learning through reflection as a situated and dynamic process in which available environmental information, learning activities,…

El tiempo en las clases de programación: ''Hacés y hacés y no te importa si tocó el timbre''

2021

A través de un estudio de caso en tres escuelas secundarias técnicas con orientación en programación se realizó una investigación cualitativa de corte etnográfica en la que se registraron los modos en que las y los estudiantes resuelven tareas de programación y organizan sus momentos de descanso. Recuperando las experiencias estudiantiles, se pudo observar cómo vivencian el tiempo cuando hay proyectos con desafíos cognitivos interesantes, en donde los cortes en su jornada escolar están fuertemente vinculados a la resolución de actividad escolar propuesta en vez de la estructura del horario escolar. Los recreos se ligan al sentido de la tarea, donde los descansos se vinculan a tres momentos …

Ethics and economics, friends or foes? An educational debate

2004

This paper reviews an ongoing debate about moral standards for vocational education in German speaking countries. At the centre of the controversy is the question of universalistic versus domain‐specific moral orientations, namely the question of whether business people ought to develop different moral points of view in different situations (such as ‘private’ versus ‘professional’). Of pivotal importance in this context is also a prominent ethical approach (by Karl Homann, a philosopher in the tradition of liberal economists) which serves as a foundation for those who advocate domain specificity and which is strongly criticized by their counterparts. This approach is also presented, since t…
