Retrotransposons represent the most labile fraction for genomic rearrangements ...

Understanding how increased genome size and diversity within polyploid genomes impacts plant evolution and breeding continues to be challenging. Although historical studies by McClintock suggested the importance of transposable elements mediated by polyploidisation on genomic changes, data from plant crosses remain scarce. Despite the absence of a conclusive proof regarding autonomous retrotransposon movement i...

Clinical Dilemma in the Treatment of a Patient with Microangiopathic Haemolytic...

While haemolytic uraemic syndrome in children is predominantly associated with Shiga toxin -producing Escherichia coli (typically 0157:H7), some cases occur without associated diarrhoea, or as the manifestation of an underlying disorder other than infection. Haemolytic uraemic syndrome is characterised by microangiopathic anaemia, thrombocytopaenia and renal failure, on occasion accompanied by severe hypertensi...

Distribution patterns of phosphorylated Thr 3 and Thr 32 of histone H3 in plant...

Cell cycle dependent phosphorylation of conserved N-terminal tail residues of histone H3 has been described in both animal and plant cells. Through cytogenetic approaches using different plant species we show a detailed description of distribution patterns of phosphorylated histone H3 at either threonine 3 or threonine 32 in mitosis and meiosis. In meristematic cells of the large genome species Secale cereale, ...

Full-scale measurements for evaluation of coal dust release from train wagons w...

The paper describes a full-scale study performed to evaluate the amount of coal dust released by eolian erosion from partly covered train wagons over runs of 350 km. The experimental setup designed for this study is described along with the effectiveness assessment of two types of dust collectors. Airflow statistics are reported for the region immediately above the top level of the wagons. Visualisation tests f...

Daytime sleepiness and academic performance in medical students

This report presents an analysis of the complaints of increasing daytime sleepiness as well as a study on their possible effects on the academic performance of medical students at the University of Brasilia. The Epworth Sleepiness Scale was applied to 172 medical students, at the beginning of August 1997 and at the end of November 1997. Academic performance was measured by analyzing the number of SS grades (fro...
