We read with interest the important prospective natural history study of respiratory virus infections (RVI) in lung transplant recipients by Bridevaux et al. Although the authors were unable to find an association between acute rejection and RVI, they acknowledge the possibility that RVI might predispose to chronic rejection, bronchiolitis obliterans syndrome (BOS). The association between BOS ...

Background: Right ventricular infarction (RVI) is frequently associated with inferior wall myocardial infarction (MI). Methods: This study was designed to identify the burden of RVI in patients presenting with inferior wall MI (n=50) by right precordial electrocardiogram (ECG) and comparing it with echocardiography (ECHO). Results: Their mean age was (54.5 ± 11.9 years); there were 42 males. ST...

Tritrichomonas foetus was shown to undergo a regulatory volume increase (RVI) when it was subjected to hyperosmotic challenge, but there was no regulatory volume decrease after hypoosmotic challenge, as determined by using both light-scattering methods and measurement of intracellular water space to monitor cell volume. An investigation of T. foetus intracellular amino acids revealed a pool siz...

Hypertonicity is a stressful stimulus leading to cell shrinkage and apoptotic cell death. Apoptosis can be prevented if cells are able to activate the mechanism of RVI (regulatory volume increase). This study in mIMCD3 cells presents evidence of a permissive role of the EGFR (epidermal growth factor receptor) on RVI, achieved for the most part through the two main EGFR-triggered signalling chai...

This paper explores some of the issues in the improvement of the performance of Real−Valued Indexed (RVI) arrays using dynamic load balancing. RVI arrays are a possible extension to FORTRAN which allow the programmer to express spatial problems in an intuitive manner allowing the compiler and run−time environment flexibility in the actual storage layout of the data. While RVI arrays in general ...

To test the sensitivity and specificity of hemodynamic criteria for acute right ventricular infarction (RVI), two groups of patients with anatomically proved acute myocardial infarction and hemodynamic monitoring were studied. Group A included 22 patients acute RVI and group B, 38 with infarction confined to the left ventricle. In both groups, the closest relation between right atrial and pulmo...

OBJECTIVES We assessed the role of late enhancement cardiovascular magnetic resonance imaging (LE-CMR) for the diagnosis of right ventricular infarction (RVI). BACKGROUND Right ventricular infarction occurs in about one-half of patients with inferior myocardial infarction (MI). It is associated with an unfavorable prognosis, but established methods often lack the diagnostic accuracy to detect...

Apoptosis is a stochastic, physiological form of cell death that is characterized by unique morphological and biochemical properties. A defining feature of apoptosis in all cells is the apoptotic volume decrease or AVD, which has been considered a passive component of the cell death process. Most cells have inherent volume regulatory increase (RVI) mechanisms to contest an imposed loss in cell ...

OBJECTIVES This study assessed the prognostic impact of right ventricular involvement (RVI) in streptokinase-treated patients with inferior acute myocardial infarction (AMI) stratified for small or large AMI. BACKGROUND Only scant data exist from small studies about the impact of reperfusion therapy on survival in patients with RVI during inferior AMI. METHODS Right ventricular involvement ...
