In this study, we introduced a simple method to determine the moment of inertia using a dynamometer. In order to evaluate the developed method, one male was required to test for his forearm including the hand on a dynamometer. In the process of finding moment of inertia, three different passive speeds, i.e. 240°/s, 270°/s, and 300°/s, were performed to confirm whether the calculated values at t...

Data errors in electronic health records have been shown to have the potential to adversely impact the conclusions drawn from clinical research. We prospectively studied the efficacy of a new alert to infer errors in previously stored data and to decrease the frequency of data entry errors, in an attempt to improve the quality of data for clinical trials. For the purpose of this study, we monit...

Almost all available sets of height growth reference values are constructed in a cross-sectional manner, except for a few studies in which longitudinal sampling was used. Such reference values are, however, flawed because of considerable individual variation in the timing of puberty, especially among children with early or late pubertal maturation. An additional complicating factor is that the ...

Measurement of glycated proteins can be of use in diagnosis and monitoring of diabetic dogs. Its use in monitoring can be facilitated by comparison of results with a reference interval derived from levels in normal dogs. In this study, a commercial immunoturbidometric assay was used to measure glycosylated haemoglobin in 15 normal dogs over a 5-week period. Following statistical analysis of the...

BACKGROUND Improvement in reference interval estimation using a new outlier detection technique, even with a physician-determined healthy sample, is examined. The effect of including physician-determined nonhealthy individuals in the sample is evaluated. METHODS Traditional data transformation coupled with robust and exploratory outlier detection methodology were used in conjunction with vari...

Foreword Technology allows the monitoring of ever denser and longer serial biological and physical environmental data. This in turn allows the recognition of time structures, chronomes, including, with an ever broader spectrum of rhythms, also deterministic and other chaos and trends. Chronomics1 thus resolves the otherwise impenetrable “normal range” of physiological variation and leads to new...

BACKGROUND A reference interval (RI) for the circulating concentration of anti-dsDNA antibody is essential for clinicians to interpret laboratory results and make clinical decisions. Therefore, we aimed to establish the RI for anti-dsDNA antibody in the Chinese Han population. METHODS This study was designed and carried out in accordance with guideline C28-A3, which is proposed by the Interna...

OBJECTIVES To measure urine concentrations of sulfated glycosaminoglycans (GAGs), determine optimal storage conditions for urine samples, establish a reference range, and determine whether there is correlation between 24-hour total urine GAG excretion and the GAG-to-creatinine ratio (GCR). ANIMALS 14 healthy adult dogs. PROCEDURE Single urine sample GAG concentrations and GCRs were measured...

The basic requirement for a good calibration is representative data. This paper outlines techniques for selecting samples from an existing population. The concept of factorial designs is explained, and three ways of applying experimental design to generate representative data are described. These are: to vary the experimental conditions; focus on some of the parameters of interest directly (ref...

AIM Limited data are available about the use of Doppler myocardial imaging (DMI) in small animals. We intend to provide reference values for velocity, strain and strain rate in a large group of healthy rats and studied the reproducibility and repeatability of these parameters. METHODS AND RESULTS A total of 33 male Wistar rats (503+/-41g) underwent baseline transthoracic echocardiography with...
