- Comparative analysis of multiple genomes in a phylogenetic framework dramatically improves the precision and sensitivity of evolutionary inference, producing more robust results than single-genome analyses can provide. The genomes of 12 Drosophila species, ten of which are presented here for the first time (sechellia, simulans, yakuba, erecta, ananassae, persimilis, willistoni, mojavensis, virilis and grimshawi), illustrate how rates and patterns of sequence divergence across taxa can illuminate evolutionary processes on a genomic scale. These genome sequences augment the formidable genetic tools that have made Drosophila melanogaster a pre-eminent model for animal genetics, and will further catalyse fundamental research on mechanisms of development, cell biology, genetics, disease, neurobiology, behaviour, physiology and evolution. Despite remarkable similarities among these Drosophila species, we identified many putatively non-neutral changes in protein-coding genes, non-coding RNA genes, and cis-regulatory regions. These may prove to underlie differences in the ecology and behaviour of these diverse species.

- Here we report a high-quality draft genome sequence of the domestic dog (Canis familiaris), together with a dense map of single nucleotide polymorphisms (SNPs) across breeds. The dog is of particular interest because it provides important evolutionary information and because existing breeds show great phenotypic diversity for morphological, physiological and behavioural traits. We use sequence comparison with the primate and rodent lineages to shed light on the structure and evolution of genomes and genes. Notably, the majority of the most highly conserved non-coding sequences in mammalian genomes are clustered near a small subset of genes with important roles in development. Analysis of SNPs reveals long-range haplotypes across the entire dog genome, and defines the nature of genetic diversity within and across breeds. The current SNP map now makes it possible for genome-wide association studies to identify genes responsible for diseases and traits, with important consequences for human and companion animal health.

Closing gaps in the human genome using sequencing by synthesis

- The most recent release of the finished human genome contains 260 euchromatic gaps (excluding chromosome Y). Recent work has helped explain a large number of these unresolved regions as 'structural' in nature. Another class of gaps is likely to be refractory to clone-based approaches, and cannot be approached in ways previously described. We present an approach for closing these gaps using 454 sequencing. As a proof of principle, we closed all three remaining non-structural gaps in chromosome 15.

Ionospheric plasma density irregularities measured by stimulated electromagnetic emission

- It is well known that ionospheric plasma turbulence can be conveniently generated by controlled injection of powerful high-frequency radio beams from the ground. Irradiation of the ionosphere with such radio waves leads to the formation of plasma density structures, striations, and the generation of secondary electromagnetic radiation, a phenomenon known as stimulated electromagnetic emission (SEE). In this paper we present experimental results of the dependence of SEE on decreasing excitation levels of the striations. In the experiments the frequency of the injected radio beam was varied near the fifth harmonic of the local ionospheric electron gyro frequency. We use the SEE measurements to obtain transverse length scales of the striations involved in the generation of the SEE. Our results show that different spectral features of the SEE display different temporal dynamics, suggesting that they are related to striations with different transverse length scales (1 less than or similar to L-perpendicular to less than or similar to 25 m).

- Objectives: Seventy-five centers from many countries have applied for a login code to the WAA apheresis registry. Fifteen centers from 7 countries have been actively entering data at the internet site from 2003 until 2007. We report on data from the registry so far. Methods: This is a web-based registry. A link is available from the WAA homepage (www.worldapheresis.org). So far data from 2013 patients (12,448 procedures) have been included. A median of 6 treatments have been performed (range 1140). Mean age 51 years (range 1-94 years; 45% women). Seven percent of the patients were <= 21 years and 4% were <= 16 years. Results: The purpose of the apheresis procedure was therapeutic in 67% and retrieval of blood components in 33% Main indications: neurological and hematological diseases, lipid apheresis and stemcell collection (autologous, and some allogeneic). Blood access: peripheral vessels (71%), central dialysis catheter through jugular (6.5%) or subclavian veins (6.7%), femoral vein (8%) and AV fistula (4%). ACD was used for anticoagulation in 73% of the procedures. Albumin was mainly used as replacement fluid. Adverse events (AE) were registered in 5.7% of the procedures. AE was graded as mild (2.5%), moderate (2.7%) or severe (0.5%). No death occurred due to treatment. The procedures were interrupted in 2.6%. Most frequent AEs were blood access problems (29%), tingling around the mouth (20%), hypotension (18%), and urticaria (9%). There were significant differences between the centers regarding mild and moderate AEs. Data indicate that centers using continuous infusion of calcium had fewer AEs. Conclusion: There was a limited number of severe AEs. Centers use various standard procedures for apheresis. By learning from the experience of others the treatment quality will improve further. In the near future, an update of the registry will enable more extensive evaluation of the data.
