OBJECTIVE Prolonged air leak (PAL) after pulmonary surgery is a frequent occurrence and is reported to cause increased length of stay (LOS) and hospital costs although the costs directly attributable to PAL have never been published. The present study aims to compare the prevalence of pulmonary complications (atelectasis, pneumonia and pleural empyema) in patients with or without PAL and to qua...

Objective To examine the impact of acute classroom movement break (CMB) and physically active learning (PAL) interventions on physical activity (PA), cognition, academic performance and classroom behaviour. Design Systematic review. Data sources PubMed, EBSCO, Academic Search Complete, Education Resources Information Center, PsycINFO, SPORTDiscus, SCOPUS and Web of Science. Eligibility cr...

Previously, we found that phenolic content and antioxidant capacity (AOX) in carrots increased with wounding intensity. It was also reported that UV radiation may trigger the phenylpropanoid metabolism in plant tissues. Here, we determined the combined effect of wounding intensity and UV radiation on phenolic compounds, AOX, and the phenylalanine ammonia-lyase (PAL) activity of carrots. Accordi...

PURPOSE Sedentary habits are strongly associated with increase of cardiovascular risk factors. The present study aimed to verify the role of accelerometry in identifying sedentary behavior, and the possible short term positive effect of this intervention on some anthropometric variables in a group of patients with cardiovascular risks factors. METHODS To quantify daily Spontaneous Motor Activ...

The prevalence of overweight and obesity in children has risen greatly worldwide. Diet and poor physical activity are the two risk factors usually examined, but epidemiological evidence exists suggesting a link between sleep duration and overweight/obesity in children. The aim of this study was to describe the relationship among body mass index (BMI), diet quality, physical activity level, and ...

While the mechanisms underlying quantitative resistance of plants to pathogens are still not fully elucidated, the Pathogen-Associated Molecular Patterns (PAMPs)-triggered response model suggests that such resistance depends on a dynamic interplay between the plant and the pathogen. In this model, the pathogens themselves or elicitors they produce would induce general defense pathways, which in...

Several compounds have been identified that display low-efficacy, "partial substrate" activity. Here, we tested the hypothesis that the mechanism of this effect is a slower rate of induced neurotransmitter efflux than that produced by full substrates. Biogenic amine transporter release assays were carried out in rat brain synaptosomes and followed published procedures. [(3)H]1-methyl-4-phenylpy...

OBJECTIVES In an innovative therapeutic exploitation against antibiotic-resistant Streptococcus pneumoniae, here we have evaluated the in vitro activity of a purified bacterially-encoded cell wall lytic enzyme, LytA (the major pneumococcal autolysin), and compared it with those of Cpl-1 and Pal (pneumococcal phage lytic enzymes) and two antibiotics versus four pneumococcal strains. METHODS Tw...

A heterologous probe encoding phenylalanine ammonia-lyase (PAL) was used to identify PAL clones in cDNA libraries made with RNA from young leaf tissue of two Populus deltoides x P. trichocarpa F1 hybrid clones. Sequence analysis of a 2.4-kb cDNA confirmed its identity as a full-length PAl clone. The predicted amino acid sequence is conserved in comparison with that of PAL genes from several oth...

The recombinant plasmid pAL-A3 bears a (poly ManA) alginate lyase-encoding gene that originates from the marine bacterium ATCC 433367 (Brown et al., Appl. Environ. Microbiol. (1991) 57, 1870-1872). The alginate lyase produced by Escherichia coli TC4 harbouring pAL-A3 was purified to protein homogeneity and the corresponding gene sequenced, giving access to the first known primary structure of a...
