BACKGROUND Age-related balance impairments, particularly in mediolateral direction (ML) may cause falls. Sufficiently sensitive and reliable ML balance tests are, however, lacking. This study is aimed to determine (1) the effect of age on and (2) the reliability of ML balance performance using Center of Mass (CoM) tracking. METHODS Balance performance of(More)
BACKGROUND One in every 1000 units of platelets is bacterially contaminated, which puts patients at risk for transfusion-associated sepsis and death. However, there is currently no screening test in place to detect contaminated units. The use of commercially available multiple-reagent urine dipsticks for this purpose was evaluated.

We report on the MR appearance of acute myocardial infarction in a 61-year-old man with Ehlers-Danlos syndrome using motion-independent, T2-weighted echo train spin echo and immediate post-gadolinium three-dimensional gradient echo imaging performed as an MRI angiographic study of the aortic arch. The region of acute infarction was of high signal intensity(More)
In this study, three techniques for measuring the free fractions of phenobarbital and phenytoin were compared: equilibrium dialysis, ultrafiltration, and the Hummel and Dreyer method for gel permeation chromatography. In their therapeutic range (15-40 and 10-20 mg/L, respectively) the free fractions of phenobarbital and phenytoin were independent of the(More)
