Twenty-four isolates of Actinobacillus seminis were typed by PCR ribotyping, repetitive extragenic palindromic element (REP)-based PCR, and enterobacterial repetitive intergenic consensus (ERIC)-based PCR. Five types were distinguished by REP-PCR, and nine types were distinguished by ERIC-PCR. PCR ribotyping produced the simplest pattern and could be useful for identification of A. seminis and ...

While almost all collision detection algorithms have been linked to a particular object representation scheme, few attempts have been made using hybrid methods to exploit the advantages of multiple representations of objects. In this paper we present a collision detection algorithm based on a dual b-rep/CSG representation of concave polyhedra initially represented in b-rep. Our method naturally...

Rab GTPases require special machinery for protein prenylation, which include Rab escort protein (REP) and Rab geranylgeranyl transferase (RGGT). The current model of Rab geranylgeranylation proposes that REP binds Rab and presents it to RGGT. After geranylgeranylation of Rab C-terminal cysteines, REP delivers the prenylated protein to membranes. The REP-like protein Rab GDP dissociation inhibit...

Repetitive-element PCR (rep-PCR) fingerprinting is a promising molecular typing tool for Escherichia coli, including for discriminating between pathogenic and nonpathogenic clones, but is plagued by irreproducibility. Using the ERIC2 and BOXA1R primers and 15 E. coli strains from the ECOR reference collection (three from each phylogenetic group, as defined by multilocus enzyme electrophoresis [...

introduction: p. aeruginosa is an important multi-drug resistant (mdr) opportunistic pathogen in hospital-acquired infections. several methods based on dna analysis have been used for investigating genetic diversity of p. aeruginosa isolates. among them, rep‑pcr typing has been introduced as a rapid, low cost method with high discriminatory power. the aims of this study were to investigate geno...

BACKGROUND We describe the use of a conceptual framework and implementation protocol to prepare effective health services interventions for implementation in community-based (i.e., non-academic-affiliated) settings. METHODS The framework is based on the experiences of the U.S. Centers for Disease Control and Prevention (CDC) Replicating Effective Programs (REP) project, which has been at the ...

In order to study the epidemiology of Salmonella Enteritidis outbreaks and determine the source of contamination so that a recurrence can be avoided, detailed characterization is necessary. Thus, the purpose of this study was to verify whether rep-PCR was able to discriminate among Salmonella Enteritidis isolates. Phage typing, detection of virulence genes and antimicrobial resistance testing w...

Retail energy providers (REPs) can employ different strategies such as offering demand response (DR) programs, participating in bilateral contracts, and employing self-generation distributed generation (DG) units to avoid financial losses in the volatile electricity markets. In this paper, the problem of setting dynamic retail sales price by a REP is addressed with a robust optimization techniq...

Got a beef with servery food? A formalization of the college food representative job description aims to make students ' requests, comments and complaints regarding the serveries more easily heard, as well as help new students deal with their personal dietary restrictions. The revisions, drafted by Nutrition & Body Image Specialist Maria Tsakalis, will standardize the food rep position across t...
