• inhalation
  • Nonetheless, clinical syndromes consistent with chronic bronchitis or airway obstruction, in particular among persons experiencing heavy organic dust inhalation, were also well described throughout the 19th century (1, 2). (cdc.gov)
  • epithelial
  • To determine if relaxation responses caused by hypertonic solutions involved airway epithelial cell shrinkage, IPT were challenged intraluminally with isotonic mannitol, urea, NMDG, Glu or NaCl. (cdc.gov)
  • eosinophils
  • Eosinophils in the airways were detected using enzyme histochemistry and quantified using computer-assisted image analysis. (cdc.gov)
  • However, TDI-GSA challenge did not result in an elevation of eosinophils in the airways, compared with control animals. (cdc.gov)
  • mechanism
  • In addition, the resistance is caused by arterioles, because the rim has two sets of arterioles, constituting the main mechanism to vary the blood flow. (hubpages.com)
  • relaxation
  • Delivery of modified Krebs-Henseleit solution (MKHS) of raised osmolarity (added NaCl or KCl) to the lumen of methacholine (MCh)-contracted IPT results in a relaxation response of the airway smooth muscle that is mediated by epithelium-derived relaxing factor (EpDRF). (cdc.gov)
  • pressure
  • The airway resistances of newly commercialized PanjeTM Low Pressure devices could not be distinguished from those calculated for previously commercialized, Regular Pressure Voice Button devices. (asha.org)
  • Airway resistances of Blom-Singer® Low Pressure devices increased systematically as a function of flow rate. (asha.org)
  • The RBF is directly proportional to the pressure gradient between the renal arteries and veins, and is inversely proportional to the resistance of the renal vessels. (hubpages.com)
  • But blood flow remains constant, because the extent to which blood pressure rises or lowers, renal resistance has to increase or decrease proportionally. (hubpages.com)
  • Ten subjects underwent treadmill exercise at 5.6 km/h over one hour while wearing each of three identical appearing, cup-shaped, prototype filtering facepiece respirators that differed only in their filter resistances (3 mm, 6 mm, and 9 mm H2O pressure drop). (cdc.gov)
  • therefore
  • Therefore, resistance is greatest at the bronchi of intermediate size, in between the fourth and eighth bifurcation. (wikipedia.org)
  • Therefore, filtering facepiece respirators with filter resistances at, or below, this level may not impact the wearer differently physiologically or subjectively from those with filter resistances only slightly above this threshold at low-moderate work rates over one hour. (cdc.gov)
  • flow
  • The flow energy loss (head loss) through a cast of canine central airways is found to be nearly independent of flow direction. (asme.org)
