INTRODUCTION Atrial fibrillation (AF) frequently coexists with other cardiovascular diseases. OBJECTIVES The aim of this study was to assess the prevalence of AF in outpatients with stable coronary artery disease (CAD) and to determine clinical and laboratory parameters associated with the higher prevalence of this arrhythmia. In addition, we compared the indications for antithrombotic treatm...

Multi-particle Markov chains L(N) are stochastic systems consisting of M(N) noninteract-ing particles moving according to the law of some \one-particle" nite Markov chain K(N). Our goal is to nd the convergence time to equilibrium T(N) 1, 2] for the sequence of Markov chains L(N) in the situation when the number of particles M(N) tends to innnity and the \size" of the one-particle chain K(N) gr...

Increasingly sophisticated technologies, such as On-Line Analytical Processing (OLAP) and Geospatial Information Systems (GIS), are being leveraged for conducting community health assessments (CHA). Little is known about the usability of OLAP and GIS interfaces with respect to CHA. We conducted an iterative usability evaluation of the Spatial OLAP Visualization and Analysis Tool (SOVAT), a soft...

The Community Health Agent (CHA) has traditionally been linked to doctors and nurses, being considered exclusive 'property' of these professionals. Historically, oral health tended to operate isolated, disconnecting the mouth from the rest of the body and the individual from his environment. The Family Health Program (FHP) points to important changes in the organization of services as well as i...

A composting experiment was carried out to assess the best parameters as indicators for degree of compost maturity and to determine humification indices for practical use. The effect of humic acids extracted on soil microorganisms growth was also simultaneously investigated in vitro under axenic conditions. The parameters used were oxidizable carbon (Co), alkaline-extractable carbon (Cex), humi...

For long-term culture, murine adipose-derived stromal cells (mADSCs) at latter passages demonstrated a marked decline in proliferative activity, exhibited senescent morphology and reduced differentiation potentials, particularly osteogenesis. To extend the lifespan of mADSCs, two culture conditions containing hyaluronan (HA) was compared in our study, one as a culture medium supplement (SHA), a...

We have searched for close and faint companions around T Tauri stars in the Chamaeleon star forming region. Two epochs of direct imaging data were taken with the VLT Adaptive Optics instrument NaCo in February 2006 and March 2007 in Ks band for the classical T Tauri star CT Cha together with a Hipparcos binary for astrometric calibration. Moreover a J band image was taken in March 2007 to get c...

Antllocyanin-rich crops have attracted attention in recent years because of their health benefits, and anthocyanin-rich tea is one of these crops. 'F95181' (Camellia sinensis) was developed for breeding anthosyanin-rich tea cultivars and registered as a new parental line 'Cha Chuukanbohon Nou 6' (C. sinensis) in 2004. 'F95181' was selected from an interspecific cross betweell C. taliensis (a wi...

Cryodynamic hand angiography (CHA) with angiograms done before, just after, and during rewarming following hand immersion in ice water was performed in 39 patients with Raynaud's syndrome and eight volunteers without it. The normal response to cold stimulus was angiographically evident as mild, transient digital arterial constriction. Most of the patients with Raynaud's syndrome, in addition to...

Hemosuccus pancreaticus, hemorrhage from the papilla of Vater via the pancreatic duct, is a rare entity. It is the least frequent cause of upper gastrointestinal bleeding (1 in 5000) and is usually caused by chronic pancreatitis, pseudo-aneurysm, or pancreatic tumors [1]. Only 2% of HP involves the hepatic arteries [2]. HP is difficult to diagnose because the bleeding is intermittent and not al...
