13. Ultrasound assessment of normal hemidiaphragmatic movement: relation to inspiratory volume.
BACKGROUND--Traditionally the radiological assessment of diaphragmatic movement has relied on fluoroscopy. Ultrasound scanning has recently been shown to be a sensitive and reproducible method of assessing hemidiaphragmatic movement in normal subjects. A study was undertaken to examine how movement of the diaphragm measured by ultrasound scanning relates to

14. Influence of the thyroid state on left ventricular tension-velocity relations in the intact, sedated dog
The mechanical properties of left ventricular contraction were described in terms of tension, velocity, length, and time in closed-chest, sedated normal, hypothyroid, and hyperthyroid dogs. Heart rate was controlled at 150 beats/min, and instantaneous contractile element velocity was calculated from left ventricular pressure and its first derivative during i

15. Fatal Bilateral Chylothorax in Mice Lacking the Integrin α9β1
Members of the integrin family of adhesion receptors mediate both cell-cell and cell-matrix interactions and have been shown to play vital roles in embryonic development, wound healing, metastasis, and other biological processes. The integrin α9β1 is a receptor for the extracellular matrix proteins osteopontin and tenacsin C and the cell surface immunoglob

16. Idiopathic scoliosis. Mechanical properties of the respiratory system and the ventilatory response to carbon dioxide.
The aims were to examine the effects of scoliosis (angle), and age on lung volumes, elastic properties of the respiratory system, and the ventilatory response to CO2. The mean age of the 55 patients was 25.4 plus or minus SEM 2.5 yr, and the mean angle was 80 plus or minus SEM 4.2. The mean plus or minus SEM percent predicted lung volumes were vital capacity

17. Left ventricular function in experimental aorto-caval fistula with circulatory congestion and fluid retention
The mechanical properties of left ventricular contraction were described in terms of tension, velocity, length, and time in closed-chest, sedated dogs in which a large aorto-caval fistula had resulted in circulatory congestion, and the results were compared with those in normal dogs. Instantaneous contractile element velocity was calculated from left ventric

18. Pulmonary function in chronic renal failure: effects of dialysis and transplantation.
Many possible pulmonary complications of renal disease have been described, but little is known of their physiological importance or the effects on them of different forms of renal replacement therapy. Four groups were recruited, each containing 20 patients. The groups consisted of patients with chronic renal failure before dialysis (group 1); patients recei
