Epidemiological evidence indicates that environmental air pollutants are positively associated with the development of chronic vascular disease; however, the mechanisms involved have not been fully elucidated. In the present study we examined molecular pathways associated with chronic vascular disease in atherosclerosis-prone apolipoprotein E-deficient (ApoE(-/-)) mice, including markers of vas...
A study on the application of V(2)O(5)/WO(3)/TiO(2) (VWT) as the sensitive material for resistive-type SO(2) sensor was conducted, based on the fact that VWT is a well-known catalyst material for good selective catalytic nitrogen oxide reduction with a proven excellent durability in exhaust gases. The sensors fabricated in this study are planar ones with interdigitated electrodes of Au or Pt. T...
rate. In the USA, the introduction of federal car exhaust emission standards in 1968 did lead to a reduction in deaths from exhaust poisoning (Clarke & Lester, 1987). EC legislation regarding exhaust emissions has now been introduced into the UK, and the use of catalytic converters (which reduce exhaust carbon monoxide content by 80-90%) is becoming more widespread. The case of a failed suicide...
Background & Aim : Endotracheal suctioning is one of the most frequently used methods for airway clearance in patients under mechanical ventilation. Chest physiotherapy techniques such as expiratory rib cage compression before endotracheal suctioning can be used as a means to facilitate mobilizing and removing airway secretions and improving alveolar ventilation. This study was carried out to...
