To explore associations of exposure to ambient and indoor air particulate and bio-aerosol pollutants with cardiovascular and respiratory disease markers, we utilized seven repeated measurements from 48 elderly subjects participating in a 4-week home air filtration study. Microvascular function (MVF), lung function, blood leukocyte counts, monocyte adhesion molecule expression, C-reactive protei...

The size and shape of a surfactant aggregate could be altered by using supersaturation like in crystal growth, rather than applying common laws that drive surfactant aggregate formation.

OBJECTIVE To determine whether use of the click test, a rapid bedside test of surfactant function, results in earlier and more appropriate surfactant administration in ventilated preterm infants than does usual early rescue treatment. STUDY DESIGN Ventilated preterm infants (n = 126) with inspired oxygen >/=25% and mean airway pressure >/=7 cm H(2)O were randomized in gestational strata (<28 ...

BACKGROUND Extensive biochemical and biophysical changes of the pulmonary surfactant system occur in the acute respiratory distress syndrome (ARDS). METHODS The effect of intrabronchial administration of a recombinant surfactant protein C-based surfactant preparation (Venticute) on gas exchange, surfactant composition and function was investigated in 31 patients with ARDS in a randomised cont...

Identifying the vital states of trapped survivors during post-disaster rescue missions can result in improved strategies and provide injury pre-diagnosis information. The most effective method is use bio-radar based non-contact measurements. Presently, techniques focus on detecting locating. Herein, a to identify with an ultra-wideband proposed, while simulating condition Beagle dogs. This inve...

this paper presents density functional theory and non-equilibrium green’s function based first principles calculations to explore the sensing property of adenine and thymine based hetero-junction chins for ammonia and phosphine gas molecules. this modeling and simulation technique plays an important and crucial role in the fast growing semiconductor based nanotechnology field. the hetero-juncti...

Langmuir isotherms and fluorescence and atomic force microscopy images of synthetic model lung surfactants were used to determine the influence of palmitic acid and synthetic peptides based on the surfactant-specific proteins SP-B and SP-C on the morphology and function of surfactant monolayers. Lung surfactant-specific protein SP-C and peptides based on SP-C eliminate the loss to the subphase ...
