DEFINITION Preservation is the set of processes that maintain the authenticity, integrity, and chain of custody of records for long periods of time. Authenticity is defined as the management of provenance information about the creation of the record. Integrity is defined as the ability to create an authentic copy. Chain of custody tracks all processing done to the record, including migration to...

Relatively few large-scale faecal DNA studies have been initiated due to difficulties in amplifying low quality and quantity DNA template. To improve brown bear faecal DNA PCR amplification success rates and to determine post collection sample longevity, five preservation methods were evaluated: 90% ethanol, DETs buffer, silica-dried, oven-dried stored at room temperature, and oven-dried stored...

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...

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...
