OBJECTIVE To validate the psychometric properties of the questionnaire on hand function assessment in leprosy. METHODS Study conducted with a convenience sample of 101 consecutive patients in Brasília (Central-Western Brazil), from June 2008 to July 2009. The individuals were adults affected by leprosy, with impairment of the ulnar, median and radial nerves. Interobservers and intraobserver r...

We evaluated the effect of initial spacing on distribution Eucalyptus grandis x urophylla tree diameters in a Nelder wheel design. The study area was west-central Brazil. A design with three repetitions used. This provides 432 planting spots per plot/repetition. Planting density varied from 0.50 m² to 41.25 m². diameter at breast height measured for all plants every four months until 36 age, to...

BACKGROUND Using computational fluid dynamics (CFD) to compute the hemodynamics in cerebral aneurysms has received much attention in the last decade. The usability of these methods depends on the quality of the computations, highlighted in recent discussions. The purpose of this study is to investigate the convergence of common hemodynamic indicators with respect to numerical resolution. METH...

OBJECTIVE To compare oxygen saturation index (rSO2) obtained simultaneously in two different brachial muscles. DESIGN Prospective and observational study. SETTING Intensive care unit. PATIENTS Critically ill patients with community-acquired pneumonia. INTERVENTIONS Two probes of NIRS device (INVOS 5100) were simultaneously placed on the brachioradialis (BR) and deltoid (D) muscles. VA...

BACKGROUND Invalid information on dietary intake may lead to false diet-disease associations. This study was conducted to examine the relative validity of the food frequency questionnaire (FFQ) used to assess dietary intake in the Leiden Longevity Study. METHODS A total of 128 men and women participating in the Leiden Longevity Study were included in the present validation study. The performa...

Perfusion measurements using conventional laser Doppler techniques are affected by the variations in tissue optical properties. Differences in absorption and scattering will induce different path lengths and consequently will alter the probability that a Doppler shift will occur. In this study, the fraction of Doppler shifted photons and the Doppler broadening of a dynamic medium, are measured ...

On the basis of 2200 small (10-100) samples obtained from four random number populations, it is shown that the rank correlation coefficient, p, is 88 adequate a measure of concordance 88 the Pearson product-moment correlation, T. The samples were obtained by using pseudo-random linear and normal number generators for bivariate populations with expected correlation cC'efficientB, r~, of 0.0 and ...

The Pearson correlation coefficient (PCC) and the Mander's overlap coefficient (MOC) are used to quantify the degree of colocalization between fluorophores. The MOC was introduced to overcome perceived problems with the PCC. The two coefficients are mathematically similar, differing in the use of either the absolute intensities (MOC) or of the deviation from the mean (PCC). A range of correlate...
