BACKGROUND The present study aimed to investigate the relationship between Left Atrial Volume (LAV), a marker of diastolic dysfunction, and the frequency of malignant ventricular arrhythmia in the patients with left ventricular dysfunction and a previously implanted Implantable Cardioverter Defibrillator (ICD) device. METHODS This cross-sectional study was conducted on 32 patients with ischem...

Letter to the editor It is well established that heart transplantation can improve patients’ quality of life, exercise capacity and survival [1,2]. Despite of the improvement in exercise performance after heart transplant, it still remains subnormal when compared with healthy subjects [3]. Cardiac causes as chronotropic incompetence [4] and diastolic dysfunction [5] have been proposed to be rel...

OBJECTIVES We hypothesized that reductions in left atrial volume (LAV) with a cardiac resynchronization therapy-defibrillator (CRT-D) would translate into a subsequent reduction in the risk of atrial tachyarrhythmias (AT). BACKGROUND There is limited information regarding the effect of CRT-D on the risk of AT. METHODS Percent reduction in LAV at 1 year following CRT-D implantation (pre-spec...

Purified streptococcal mitogens (SMs) including erythrogenic exotoxin were compared with phytohemagglutinin (PHA) for their ability to sustain lymphadenopathy-associated virus (LAV) replication after the stimulation of normal human peripheral blood mononuclear cells and purified CD4+ and CD8+ T cells infected with LAV. Both SM and PHA supported LAV production in peripheral blood mononuclear and...

Currently, there are two main basic approaches to data integration: Global-as-View (GaV) and Local-as-View (LaV). However, both GaV and LaV have their limitations. In a GaV approach, changes in information sources or adding a new information source requires revisions of a global schema and mappings between the global schema and source schemas. In a LaV approach, automating query reformulation h...

Introduction and Summary The use of regression analysis relies on the choice of a criterion in order to estimate the coefficients of the explanatory variables. Traditionally, the least squares (LS) criterion has been the method of choice. However, the least absolute value (LAV) criterion provides an alternative. LAV regression coefficients are chosen to minimize the sum of the absolute values o...

Patients with acquired immunodeficiency syndrome (AIDS) and AIDS-related complex (ARC) have hyperimmunoglobulinemia and increased numbers of circulating immunoglobulin-secreting cells. In this paper, we studied the basis for this B cell hyperactivity. Limiting dilution studies of B cells from seven patients with ARC and four with AIDS revealed that some B cells spontaneously produced antibodies...

This paper presents a new approach to data integration which combines the previous approaches of local as view LAV and global as view GAV into a single method we term both as view BAV Our method is based on the use of reversible transforma tion sequences and combines the re spective advantages of GAV and LAV In particular in common with GAV querying processing on a global schema is simply a mat...

OBJECTIVES We studied left atrial volume (LAV) as an index of atrial size. BACKGROUND Increased left atrial dimension (LAD) measured by M-mode echocardiography is a risk factor for atrial fibrillation, stroke, and death. METHODS A random sample of residents of Olmsted County, Minnesota, age 45 years (n 2,042) underwent Doppler echocardiography with assessment of LAD and LAV. A subgroup of the p...

Peripheral blood mononuclear cells (PBMNC) from healthy donors immune to the soluble antigens tetanus toxoid (TT) and/or keyhole limpet hemocyanin (KLH) were exposed to infectious human T lymphotropic virus, type III/lymphadenopathy-associated virus (HTLV-III/LAV) with and without prior activation by TT or KLH. After exposure to the virus, PBMNC that had been activated by antigen were 10 to 100...
