OBJECTIVES To perform a meta-analysis of clinical trials and investigate the effect of stem cell therapy on dilated cardiomyopathy. METHODS A systematic literature search was carried out between May 2012 and July 2013 in PubMed, Medline, Cochrane Library, and Excerpta Medica Database (EMBASE). The study took place in the Department of Cardiology, Renmin Hospital of Wuhan University, Wuhan, Ch...

One of the major obstacles for knowledge management remains MultiWord Terminology (MWT). This paper explores the difficulties that arise and describes real world solutions implemented as part of the Parmenides project. Parmenides is being built as an integrated knowledge management package that combines information, MWT and ontology extraction methods in a semi-automated framework. The focus of...

Quality of life is an important outcome measure in patients with end-stage heart failure waiting for heart transplantation. The purpose of this study was to investigate the relationship between aspects of quality of life and physiological and psychosocial variables in patients with end-stage heart failure. A total of 123 patients participated in the study. The functional status was assessed wit...

Mallory-Weiss tears (MWTs) are mucosal lacerations caused by forceful retching and are typically located at the gastroesophageal junction. Reported cases of MWT with serious complications seen in esophagogastroduodenoscopy are limited. We report MWT in an 81-year-old woman who presented with gastric perforation by esophagogastroduodenoscopy. We discuss and indicate that hiatal hernia, atrophic ...

AbstractThe Researchers uses Satellite images for their Research work in many fields. The Satellite images have issues with their resolution. So, the images which loses their high frequency contents. And they appeared as blurred image. This paper proposes a resolution enhancement technique called Multi Wavelet Transform (MWT). This technique obtains the interpolation of high frequency sub bands...

background knee osteoarthritis (oa) is a common joint disease and several different physiotherapy protocols have been recommended to provide pain relief and improve disability in patients with knee oa. objectives in order to find the effectiveness of local vibration application on knee oa complications, a randomized controlled clinical trial was designed to assess the changes in muscle torque, ...

In this paper, we examine robust feature extraction methods for automatic speech recognition (ASR) in noise-distorted environments. Several perceptual experiments have shown that the range between 1 and 10 Hz of modulation frequency band is important for ASR. Combining the coefficients of multi-resolutional Fourier transform to split the important modulation frequency band for ASR into several ...

Automatic Multi-Word Term (MWT) extraction is a very important issue to many applications, such as information retrieval, question answering, and text categorization. Although many methods have been used for MWT extraction in English and other European languages, few studies have been applied to Arabic. In this paper, we propose a novel, hybrid method which combines linguistic and statistical a...

MOTIVATION In searching for differentially expressed (DE) genes in microarray data, we often observe a fraction of the genes to have unequal variability between groups. This is not an issue in large samples, where a valid test exists that uses individual variances separately. The problem arises in the small-sample setting, where the approximately valid Welch test lacks sensitivity, while the mo...

BACKGROUND To assess in a laboratory setting the ability to stay awake in a sample of workers of an Italian hospital and to investigate the association between that ability and the risk of occupational injury. METHODS Nine workers at the University Hospital of Udine who reported an occupational injury in the study period (cases), and seven noninjured workers (controls) underwent a polysomnogr...
