Drosophila muller f elements maintain a distinct set of genomic properties over 40 million years of evolution.

The Muller F element (4.2 Mb, ~80 protein-coding genes) is an unusual autosome of Drosophila melanogaster; it is mostly heterochromatic with a low recombination rate. To investigate how these properties impact the evolution of repeats and genes, we manually improved the sequence and annotated the genes on the D.

Hospital-wide assessment of compliance with central venous catheter dressing recommendations.

This hospital-wide assessment of central venous catheter (CVC) site maintenance evaluated a total of 420 CVC sites and found deficiencies in 31%. Internal jugular CVC dressings were the most frequently deficient type (P = 0.001).
