BK Polyomavirus in Respiratory Specimens of Patients with Respiratory Disease

Background and Aims: The role of BK and JC polyomaviruses (BKV and JCV) in the causation of respiratory disease and the natural route of transmission has not well been established. The aim of study was to determine the prevalence of BK and JC viruses in 280 respiratory samples and evaluate their contribution to respiratory disease. Materials and Methods: PCR was used to screen specimens for BK...

Extended Simple Colored Petri Nets: a Tool for Plant Simulation

Extended Simple Colored Petri Nets (ESCP-nets) are a new class of High-level Petri Nets conceived as a good trade-off between Petri Nets (P-nets) and Colored Petri Nets (CP-nets), to be used in plant simulation. ESCP-nets, while being much more convenient and compact than P-nets, are fairly simpler than CP-nets, thus being more easily implemented and more amenable to formal analysis. Furthermor...

Autoclaving as an aid in the clearing of plant specimens.

Numerous recipes exist for the clearing of plant tissues prior to examination as whole mounts (see annotated bibliography by Lersten 1967). Broadly speaking, these methods may be classified into 3 groups; mild, drastic and very drastic procedures, depending upon the severity with which the tissue is extracted by the clearing procedure. For some purposes mild procedures are all that are needed f...
