We investigated whether low arterial oxygen tension ([Formula: see text]) or hypoxia-induced plasma volume (PV) contraction, which reduces central blood (BV) and atrial distension, explain reduction in circulating natriuretic peptide (ANP) after prolonged hypoxic exposure. Ten healthy males were exposed for 4 days to hypobaric hypoxia corresponding an altitude of 3,500 m. PV changes determined ...

Postnatal response of the gall bladder to feeding was studied in 28 preterm infants (gestational age 24-37 weeks) by ultrasonography immediately before feeding and one hour after feeding. Nineteen of the infants were studied once during the first week of life, and nine infants were studied weekly from a postconceptional age of 27-31 until a postprandial gall bladder contraction was seen. A cont...

Cardiac dyssynchrony is divided into electrical dyssynchrony and mechanical dyssynchrony. Electrical dyssynchrony is associated with a prolonged conduction time in the ventricles resulting in a prolonged QRS duration [1]. Mechanical dyssynchrony presents the mechanical discoordination that is most often related to simultaneous contraction and stretch in different segments of the left ventricle ...

This study evaluated the effects of the light curing methods and resin composite composition on composite polymerization contraction behavior and resin composite adaptation to the cavity wall using μCT-3D visualization analysis and dye penetration test. Cylindrical cavities were restored using Clearfil tri-S Bond ND Quick adhesive and filled with Clearfil AP-X or Clearfil Photo Bright composite...

PURPOSE To compare urodynamic characteristics in patients with idiopathic detrusor overactivity (IDO) with those of an age matched cohort with diabetes mellitus (DM) and detrusor overactivity (DO). Secondly, to determine whether urodynamic features could help distinguish these two groups of patients. MATERIALS AND METHODS Urodynamic data was collected on 58 female patients; 29 with IDO and 29...

This research assesses the relative contribution of splenic contraction and fluid shifts out of the vascular compartment to the increases in packed cell volume associated with Agility exercises. It also aims to evaluate the changes in the concentrations of electrolytes and markers of hydration state. Fifteen dogs of both sexes were subjected to an Agility exercise of an approximate duration of ...
