Methods Thirty-seven patients with HCC treated by RFA were evaluated. Lesion number, size and segmental location, T2-weighted (w), arterial, portal-venous and venous contrast-phase, b600 diffusion-w imaging (DWI) and delayed phase contrast-enhanced imaging pattern were assessed at MRI. The separate imaging patterns as well as pretreatment clinical variables were correlated with outcome (disease...

A new index for analysis of single-case research data was proposed, Tau-U, which combines nonoverlap between phases with trend from within the intervention phase. In addition, it provides the option of controlling undesirable Phase A trend. The derivation of Tau-U from Kendall's Rank Correlation and the Mann-Whitney U test between groups is demonstrated. The equivalence of trend and nonoverlap ...

BACKGROUND Methamphetamine is a neurotoxic agent. Its chronic abuse may result in cognitive impairment with negative consequences for patients' treatment and rehabilitation. The aim of the study was to compare Wisconsin Card Sorting Test profiles of Czech subjects dependent on methamphetamine with healthy individuals. SUBJECTS AND METHODS Forty-three hospitalized Czech Caucasian patients incl...

Difficulties associated with resolving the human-chimpanzee-gorilla trichotomy demonstrate the need to assess the robustness of phylogenetic hypotheses. For distance data, such as those derived from DNA-DNA hybridization and immunological techniques, taking account of measurement error constitutes a special problem when assessing the reliability of best-fit trees. Several different methods, mos...

AIM To compare the 2-stage and 4-stage basic life support teaching technique. The second aim was to test if students' self-evaluated knowledge was in accordance with their actual knowledge. METHODS A total of 126 first-year students of the Faculty of Medicine in Ljubljana were involved in this parallel study conducted in the academic year 2009/2010. They were divided into ten groups. Five gro...

In this study, we compared the Student's t-test, Welch's and Mann-Whitney U test, in terms of their type I error rate statistical power when assumptions parametric tests are violated different situations. Materials used consisted random numbers generated using Numpy library Python programming language. All were from a normal distribution with N (0, 1) parameters. Balanced unbalanced experimenta...

A program for neuronal activity analysis is described. The applied computational techniques are standard in the field of digital processing, but the program is particular in its field of application and mode of data selection. The program, written in Turbo Pascal for the IBM-PC and compatibles, statistically compares (Mann-Whitney U-test) two sets of graphically selected data, and establishes w...

This research aims to determine the use of project-based learning (PjBL) in achievement students' mathematical problem-solving abilities. The variables this were PjBL and instrument was a description test abilities, which analyzed by testing hypothesis using Mann Whitney U test. results showed that average value students higher than conventional models. show is effective improving

STATEMENT OF THE PROBLEM The expression of minichromosome maintenance-3 (MCM3) proteins and their diagnostic value in oral mucosal dysplasia and squamous cell carcinoma (SCC) is not well known. PURPOSE This study was conducted to evaluate the usefulness of minichromosome maintenance 3 (MCM3) as a biomarker for diagnosis of oral premalignant lesions and SCC. MATERIALS AND METHOD In this stud...
