BACKGROUND Expiratory flow limitation (EFL), determined by the negative expiratory pressure (NEP) technique, can exhibit overlapping patterns in COPD, obstructive sleep apnea (OSA) and non-OSA obesity. We assessed the ability of a quantitative method to assess EFL to discriminate COPD from obese and OSA patients during NEP (-2 to -3 cm H(2)O) testing. METHODS EFL was quantified by measuring t...

Genes encoding elongation factor-like (EFL) proteins, which show high similarity to elongation factor-1alpha (EF-1alpha), have been found in phylogenetically distantly related eukaryotes. The sporadic distribution of "EFL-containing" lineages within "EF-1alpha-containing" lineages indirectly, but strongly, suggests lateral gene transfer as the principal driving force in EFL evolution. However, ...

Although studies on L2 learning strategies are a major strand of second-language research, recent research interest has focussed on language learners’ metacognitive knowledge or awareness of strategies. Previous research has shed important light on the amelioration in L2 educational practices,but little researchis focused on EFL learners in input-poor environments. This paper reports on a study...

Elderly people commonly suffer from dyspnoea, which may stem from expiratory flow limitation (EFL). The relationship between EFL, as assessed by the negative expiratory pressure method and spirometric indices, was investigated in an elderly French population. Subjects, aged 66-88 yrs, filled in socio-demographic and standardised questionnaires, which dealt with: medical history, smoking status ...

To quantify gene expressions by quantitative reverse transcription-PCR (Q-RT-PCR) in natural diatom assemblages, it is necessary to seek a biomass reference specific to the target species. Two housekeeping genes, TBP (encoding the TATA box-binding protein) and EFL (encoding the translation elongation factor-like protein), were evaluated as candidates for reference genes in Q-RT-PCR assays. Tran...

This paper reports on the experiences of four Australian teachers who provide English as a Foreign Language (EFL) instruction to Indonesian secondary school students in a regional area of Central Java, Indonesia. These four teachers were all native English speakers and experienced qualified teachers, however, the Australian State Department of Education that sent them to Indonesia did not provi...

In Caenorhabditis elegans, EFL-1 (E2F), DPL-1 (DP) and LIN-35 (pRb) act coordinately in somatic tissues to inhibit ectopic cell division, probably by repressing the expression of target genes. EFL-1, DPL-1 and LIN-35 are also present in the germline, but do not always act together. Strong loss-of-function mutations in either efl-1 or dpl-1 cause defects in oogenesis that result in sterility, wh...

We investigated whether expiratory muscle loading induced by the application of expiratory flow limitation (EFL) during exercise in healthy subjects causes a reduction in quadriceps muscle blood flow in favor of the blood flow to the intercostal muscles. We hypothesized that, during exercise with EFL quadriceps muscle blood flow would be reduced, whereas intercostal muscle blood flow would be i...

BACKGROUND Expiratory flow limitation (EFL) during tidal breathing is common in patients with severe COPD, and a major determinant of dynamic hyperinflation and exercise limitation. EFL can be measured by the forced oscillation technique (FOT); however, the relevance to clinical parameters is not fully understood. We hypothesized that emphysema extent and pulmonary function would contribute ind...

Web 2.0 technologies are increasing in popularity, offering huge possibilities, but also bringing new challenges to language learning classes. In the context of ESL and EFL teaching and learning Web 2.0 technologies, specifically blogs and wikis can be used for teaching collaborative process writing. This study investigates previous research on the use of blogs and wikis as tools for collaborat...
