Hair bundles, the mechanically sensitive organelles of hair cells in the auditory and vestibular systems, are elastic structures that are deflected by sound or acceleration. To examine rapid mechanical events associated with mechanoelectrical transduction, we stimulated individual hair bundles with flexible glass fibers and measured their responses with a(More)
Efficient transduction by acousticolateralis organs requires that a stimulus force principally deflect hair bundles, rather than flex other structural elements. Hair bundles might therefore be expected to provide a large fraction of the impedence to shear motions of otolithic membranes and other accessory structures. We measured the stiffness for shear(More)
Comparison was made of the mental function and physical growth of 21 children in whom liver disease occurred in the first year of life with 15 patients with late (17 months of age to 12 years of age) manifestation of liver disease. Ages (mean +/- SD) at testing for the two groups was 8 +/- 3 years for the early group and 11 +/- 5 years for the late group.(More)
A prospective study in healthy infants predefining both diet fatty acid and cholesterol, from birth to age 1 year, compared response of cholesterol fractions in three groups: random assignment to 1) monounsaturated-(Hi-Mono) (n = 20), or 2) polyunsaturated-(Hi-Poly) (n = 22) fatty acid-enriched diets, or 3) non-randomized selection to breast feeding (Human(More)
We measured intellectual and motor function, social competence, and growth in 29 children (mean age 4 years 7 months) before liver transplantation and 1 year later. We used either the Bayley Scales, the Stanford-Binet Intelligence Scale, and the Minnesota Child Development Inventory (MCDI), Motor Age Quotient, or the Wechsler Scales, depending on the age of(More)
From September 1, 1984 to March 1, 1988, 201 patients were evaluated for liver transplantation. Ninety-one orthotopic liver transplants were performed on 80 children ranging in age from 3 months to 15 years. The average waiting time for a transplant was 5 months, with children less than 10 kg in weight waiting a disproportionately long time. The average(More)
The most common hepatic complications of cystic fibrosis (CF) are steatosis, fibrosis, biliary cirrhosis, atretic gallbladder, cholelithiasis, and sclerosing cholangitis. Cholestatic liver disease is a slow progressive disorder, but will stabilize for many patients. CF patients may suffer from the consequences of their liver disease and without liver(More)
We compared mental function and growth in 10 children (ages: 5-13 yrs) with end stage liver disease whose onset was in the first year of life (x age onset 0.3 yrs; range 1-12 months). Five children had chronic cholestasis: bilirubin 27±8 mg/dl, vitamin E 0.8±0.7 μg/ml, albumin 2.9±.5 g/dl; the other five were not cholestatic: bilirubin 1.5±.8 mg/dl, vitamin(More)
