To assess whether distance runners displaying uneconomical freely chosen step lengths (FCSL) could be trained to shift FCSL toward a more optimal setting, six males and three females who exhibited uneconomical FCSL [mean optimal step length (OSL) = -9.81% of leg length from FCSL; mean change in oxygen uptake (VO2) (FCSL - OSL) = 1.46 ml.kg-1.min-1](More)
The purpose of this study was to quantify daily intra-individual variability in mean step length, a basic descriptor for the running pattern. Following 60 minutes of treadmill accommodation, nine trained male subjects (X age = 34.2 yrs +/- 7.2, X VO2max = 57.0 +/- 4.8 ml.kg-1.min-1) performed daily (Mon-Fri) 6-minute treadmill runs at three submaximal(More)
PURPOSE To report the clinical outcomes with 24-month follow-up of transepithelial cross-linking using a combination of a D-alpha-tocopheryl polyethylene-glycol 1000 succinate (vitamin E-TPGS)-enhanced riboflavin solution and abbreviated low fluence UV-A treatment. METHODS In a nonrandomized clinical trial, 25 corneas of 19 patients with topographically(More)
Purpose: a time-dependent mathematical model of UV-A absorption and of riboflavin consumption During cross-linking treatments, the intensity of the UV-A shaft that exits from the rear side of a treated cornea generally varies with time. Therefore, a time-dependent mathematical model is necessary to describe cross-linking treatments. Wherein:  R A (z,t):(More)
PURPOSE To determine the cross-linking effect of a riboflavin ultraviolet-A (UV-A) corneal cross-linking treatment that is both shorter and has lower energy than the Dresden protocol. METHODS In a first experiment, 12 human corneas were presoaked with riboflavin and then irradiated with UV-A at 3 mW/cm after clearing the surface of riboflavin, with no(More)
INTRODUCTION Abdominal angina occurs in patients affected by mesenteric artery obstruction, causing postprandial episodes of visceral pain. The conventional treatment consists of vessels revascularization, but sometimes this is not applicable. CASE REPORT The authors report a case of a patient with severe abdominal angina caused by mesenteric ischemia,(More)
