BACKGROUND Lejeunea is a largely epiphytic, subcosmopolitan liverwort genus with a complex taxonomic history. Species circumscriptions and their relationships are subject to controversy; biogeographic history and diversification through time are largely unknown. METHODOLOGY AND RESULTS We employed sequences of two chloroplast regions (trnL-trnF, rbcL) and the nuclear ribosomal ITS region of 3...

Merkel cell carcinoma is an unusual, aggressive skin tumour, with a tendency to recur after its surgical extirpation. Five cases of tumours in the cervicofacial region seen at our Centre in the last 5 years are presented, along with a review of the literature, focusing on its etiopathogeneis, approach and treatment.

A remarkable feature of the 2009 pandemic H1N1 influenza virus is its efficient transmissibility in humans compared to that of precursor strains from the triple-reassortant swine influenza virus lineage, which cause only sporadic infections in humans. The viral components essential for this phenotype have not been fully elucidated. In this study, we aimed to determine the viral factors critical...

This paper presents some implementation details of a threephase to three-phase matrix converter prototype. The bidirectional semiconductor switches were built using discrete IGBTs and fast diodes.
