BACKGROUND To assess the prevalence of and relation between rupture or tenosynovitis of the Flexor Hallucis Longus (FHL) tendon and range of motion, deformities and joint damage of the forefoot in RA patients with foot complaints. METHODS Thirty RA patients with painful feet were analysed, their feet were examined clinically for the presence of pes planus and range of motion (ROM), radiograph...

Aim of this study was to estimate behavioral changes after cardiac surgery (CS). A questionnaire was sent by mail to 74 women and 122 men during May 2004 and the answers were collected by phone. For statistical analysis, the chi2-test was used. A common unhealthy habits before CS were inappropriate diet (80% of all responders), addictions to alcohol (62%) and nicotine (54%). Significantly fewer...

GPs form an integral part of Irish primary care provision. However, current information concerning general practice structure, staffing and development in Ireland is quite limited. This report provides a profile of General Practice in Ireland in 2010 drawing on a national survey of practices using a standardised questionnaire. On average, there are 2.7 GPs per practice, although one in four pra...

Two CHI genes from Chitinolyticbacter meiyuanensis SYBC-H1 encoding chitinases were identified and their protein 3D structures were predicted. According to the amino acid sequence alignment, CHI1 gene encoding 166 aa had a structural domain similar to the GH18 type II chitinase, and CHI2 gene encoding 383 aa had the same catalytic domain as the glycoside hydrolase family 19 chitinase. In this s...

ÐSince the ChiMerge algorithm was first proposed by Kerber in 1992, it has become a widely used and discussed discretization method. The Chi2 algorithm is a modification to the ChiMerge method. It automates the discretization process by introducing an inconsistency rate as the stopping criterion and it automatically selects the significance value. In addition, it adds a finer phase aimed at fea...

The aim of the study was to determine the differences in sexual behaviour and condom use as a protection against sexually transmitted infections (STI) between the first-year and the last-year students. Data were collected by filling anonymous and consented questionnaire in June of 2011 at University of Josip Juraj Strossmayer in Osijek, Croatia. Out of 857 students in the planned sample, 462 (5...

BACKGROUND The widespread use of nutritional supplements among athletes is poorly understood. The prevalence of supplement intake and users' knowledge have been researched independently leading to useful, but disconnected, information on supplement use. METHODS The 'UK Sport 2005 Drug Free Survey' data (n = 874) were re-analysed using association [chi2] and 'strength of association' tests [ph...

Feature selection is frequently used as a preprocessing step to machine learning. The removal of irrelevant and redundant information often improves the performance of learning algorithms. This paper is a comparative study of feature selection in drug discovery. The focus is on aggressive dimensionality reduction. Five methods were evaluated, including information gain, mutual information, a ch...
