Pulsed electric field (PEF)-resistant and PEF-sensitive Listeria monocytogenes strains were sublethally treated with electric pulses at 15 kV/cm for 29 micro s and held at 25 degrees C for 5 to 30 min prior to protein extraction. The levels of the molecular chaperones GroEL, GroES, and DnaJ were determined by immunoblotting. After 10 to 20 min after sublethal PEF treatment, a transient decrease...
PURPOSE Adolescents are often cited as having poor rates of compliance with medical regimens and research protocols. We quantified compliance in a cohort of urban adolescents participating in a complex research protocol in which measures were obtained without direct supervision by research personnel. METHODS A total of 54 early adolescents ages 10-13 were asked to wear a vest containing a per...
BACKGROUND Little information is available on the possible association between hourly short-term air pollution and peak expiratory flow (PEF) in asthmatic children. METHODS PEF was measured twice daily, from October through December, 2000, in 17 children aged 8 to 15 years hospitalized with severe asthma. A total of 1198 PEF measurements were made at 7 a.m. and 1175 at 7 p.m. Measurements wer...
background and objectives: pulsed electric field (pef) is a novel emerging technology which is believed to have the potential to substitute conventional thermal pasteurization (htst). in the current study pef was compared with htst based on microbial inactivation and quality attributes. materials and methods: juice was prepared by extracting it from semirum apples. they were chilled to 4ºc over...
BACKGROUND Objective measures are required that may be used as a proxy for exacerbations in asthma. The aim was to determine the sensitivity and specificity of electronic diary data to detect severe exacerbations (SEs) of asthma. A secondary aim was to identify phenotypic variables associated with a higher risk of exacerbation. METHODS In the BIOAIR study, 169 patients with asthma (93 severe ...
BACKGROUND Different lung function equipment and different respiratory manoeuvres may produce different Peak Expiratory Flow (PEF) results. Although the PEF is the most common lung function test, there have been few studies of these effects and no previous study has evaluated both factors in a single group of patients. METHODS We studied 36 subjects (PEF range 80-570 l/min). All patients reco...
The management of heart failure with reduced ejection fraction (HF-REF) has improved significantly over the last two decades. In contrast, little or no progress has been made in identifying evidence-based, effective treatments for heart failure with preserved ejection fraction (HF-PEF). Despite the high prevalence, mortality, and cost of HF-PEF, large phase III international clinical trials inv...
Hypertension, a common risk factor for cardiovascular disease, is usually diagnosed and treated based on blood pressure readings obtained in the clinic setting. Blood pressure may differ considerably when measured inside versus outside of the clinic setting. Over the past several decades, evidence has accumulated on the following 2 approaches for measuring blood pressure outside of the clinic: ...
Home blood pressure monitoring Shah and colleagues found patients with heart failure who lived in areas of socioeconomic deprivation were less likely than those in more affluent areas to be treated with recommended beta blockers. 1 We recently investigated use of home blood pressure (BP) monitoring in stroke patients registered at a deprived inner city general practice in Lambeth. In March 2008...
