Breathing at very low lung volumes might be affected by decreased expiratory airflow and air trapping. Our purpose was to detect expiratory flow limitation (EFL) and, as a consequence, intrinsic positive end-expiratory pressure (PEEPi) in grossly obese subjects (OS). Eight OS with a mean body mass index (BMI) of 44 +/- 5 kg/m2 and six age-matched normal-weight control subjects (CS) were studied...

Expiratory flow limitation (EFL), which promotes dynamic hyperinflation and increased work of breathing, often occurs in chronic obstructive pulmonary disease (COPD). The purpose of this study was to assess the effect of bronchodilators on EFL and end-expiratory lung volume in patients with moderate-to-severe COPD. EFL was assessed by applying negative expiratory pressure (NEP) at the mouth dur...

Achieving communicative competency in English classes has been a key goal in contexts where English is taught as a foreign language (EFL). During this process, however, integrating the difficulty and complexity of real life tasks into classroom teaching has often been disregarded. Lack of opportunities for authentic language use often results in learners’ gaining extensive knowledge about the t...

As arecognized psychological construct, anxietyplays aninfluential role in the invaluable experience of learning English as a Foreign Language (EFL).

Critical literacy is widely practiced in classrooms in many countries and across levels of education. Research that explores critical literacy in English as a second language (ESL) and English as a foreign language (EFL) classrooms, however, remains scarce. The few studies that do exist focus on development of critical literacy without explicit attention to development of language skills (see, ...
