PURPOSE We used what is to our knowledge a new method to estimate volume loss after partial nephrectomy to assess the relative contributions of ischemic injury and volume loss on functional outcomes. MATERIALS AND METHODS We analyzed the records of 301 consecutive patients who underwent conventional partial nephrectomy between 2007 and 2010 with available data to meet inclusion criteria. Perc...

Earlier papers (Allen and Hayes 1985,1986) described a compact axiomatic theory which provided a formal basis for temporal reasoning. This theory makes a sharp distinction between time points and periods of time. We show here, by considering possible models of the theory, that it can be slightly extended to give a better fit to intuition. In particular, the extended theory is preserved under ch...

PURPOSE Renal parenchymal volume decrease after partial nephrectomy is associated with late functional outcomes. We examined the relative effects of resection related and atrophy related volume change on late kidney function. MATERIALS AND METHODS Data were analyzed from a cohort of 187 patients who underwent open, laparoscopic or robotic partial nephrectomy between 2009 and 2011. Total chang...

Better understanding of the mechanisms of ischemia-reperfusion injury, improvement in the technique of lung preservation, and the recent introduction of a new preservation solution specifically developed for the lungs have helped to reduce the incidence of primary graft dysfunction after lung transplantation. Currently, the limitation in extending the ischemic time is more often related to the ...

Introduction: Mitral valve replacement with chordal preservation requires technical skill, long cross clamp time and prolonged ischemic time of myocardium. Materials and Methods: All patients undergoing mitral valve replacement in the Department of Cardiothoracic Surgery, Government Rajaji Hospital during December 2009 to December 2011 were included in the study. Results: All the observations a...

We are concerned in this paper by controlled Linear Time-Invariant (LTI) Multi Input Multi Output (MIMO) systems in continuous-time. We study here the preservation under strictly positive real substitutions (of zero relative degree) of coprime factorizations as well as stabilizing properties in parametrized controllers. We also tackle here both the preservation of well-posedness (of the trackin...

Increasingly, content owners are operating repositories with large, heterogeneous collections. The responsibility to provide access to these collections on the long term requires preservation processes such as planning, monitoring, and actual preservation operations such as migration and quality assurance, which have to be managed and integrated with the repositories. This article presents a su...
