[Vocal fold paralysis in the Medical University of Warsaw's Ambulatory of Phoniatry in years 2000-2011].

Introduction: Vocal fold paralysis it is an important problem in Phoniatrics' Ambulatory. There are a lot of difficulties in estimation a precise incidence of vocal fold paralysis in the population. As many as 50% of cases with paralysis might present nonspecific symptoms.

[The complications after CO2 laser endoscopic surgery for early glottic cancer].

Introduction: CO(2) laser endoscopic surgery, introduction in the treatment of early glottic malignancies in the early seventies is the method has been well studied in such cases, and its utility for these lesions is well-established. Transoral resection with the CO(2) laser, open partial laryngectomy and radiotherapy are the main options for treatment of early laryngeal cancer. As all the therapies are all equally effective in controlling an early glottic cancer the choice of treatment must consider such factors as possible complications, functional outcome and patient compliance.

Cloning and characterization of a region responsible for the maintenance of megaplasmid pTAV3 of Paracoccus versutus UW1.

Using cointegrate formation, we constructed a basic replicon of the megaplasmid/mini-chromosome pTAV3 of Paracoccus versutus UW1. It is composed of two adjacent modules, responsible for plasmid replication (rep) and partitioning (par). Functional analysis of the par region identified a determinant of incompatibility (inc2), whose presence is crucial for proper partitioning (the partitioning site).
