Anemia resulting from cancer or its treatment is an important clinical problem increasingly treated with the recombinant hematopoietic growth factor erythropoietin. To address uncertainties regarding indications and efficacy, the American Society of Clinical Oncology and the American Society of Hematology developed an evidence-based clinical practice(More)
PURPOSE To update the American Society of Clinical Oncology/American Society of Hematology (ASCO/ASH) recommendations for the use of epoetin. The guideline was expanded to address use of darbepoetin and thromboembolic risk associated with these agents. METHOD An Update Committee ("Committee") reviewed and analyzed data published since 2002 through July(More)
DNA Surveillance is a Web-based application that assists in the identification of the species and population of unknown specimens by aligning user-submitted DNA sequences with a validated and curated data set of reference sequences. Phylogenetic analyses are performed and results are returned in tree and table format summarizing the evolutionary distances(More)
PURPOSE To update American Society of Clinical Oncology/American Society of Hematology recommendations for use of erythropoiesis-stimulating agents (ESAs) in patients with cancer. METHODS An Update Committee reviewed data published between January 2007 and January 2010. MEDLINE and the Cochrane Library were searched. RESULTS The literature search(More)
BACKGROUND & AIMS Although viral quasi-species evolution may be related to pathogenesis of disease, little is known about this in hepatitis B virus (HBV); consequently, we aimed to evaluate the evolution of HBV quasi-species in patients with well-characterized clinical phenotypes of chronic hepatitis B. METHODS Four cohorts of well-defined clinical(More)
The tethered-nematode technique was adapted for use with second-stage juveniles of Meloidogyne incognita. The data demonstrate that M. incognita exhibits the same patterns of behavior as adults of the free-living nematode, Caenorhabditis elegans. The principal differences are that M. incognita is slower and less regular in its behavior than C. elegans. The(More)
Eleven microsatellite loci were isolated from an enriched genomic library from the tiger rattlesnake Crotalus tigris. Average observed heterozygosities in two populations were 0.456 and 0.427, respectively, and mean number of alleles were 7.54 (range 2-14) and 4.72 (range 2-13) respectively. No evidence of linkage disequilibrium was found across pairs of(More)
Models of nucleotide or amino acid sequence evolution that implement homogeneous and stationary Markov processes of substitutions are mathematically convenient but are unlikely to represent the true complexity of evolution. With the large amounts of data that next generation sequencing promises, appropriate models of evolution are important, particularly(More)
