This paper proposes a new transformation of arc routing problems into equivalents node routing problems, with emphasis on the transformation of Capacitated Arc Routing Problems (CARP) into Capacitated Vehicle Routing Problems (CVRP). For this last case, an analogue transformation has already been proposed in Pearn et al. [21], where each required CARP arc was mapped onto a triplet of CVRP nodes...

A method for purification of carp serum immunoglobulin (IgM), intended for the production of monoclonal antibodies, was described in the present study. Hybridomas that produce antibodies against IgM heavy chain were selected by ELISA method and Western blotting. Ascitic fluids were prepared and tested by the above mentioned methods, and their typing followed. Monoclonal antibody with the highes...

Carp erythrocytes were fractionated by angle-head centrifugation which yielded fractions with a linear increase in density. Haematological examinations revealed that the heavier red blood cells of carp had greater volumes (MCV), more haemoglobin (MCH) and higher haemoglobin concentrations (MCHC) than light ones. The same experiments with human red cell fractions yielded a decrease in MCV, const...

In the Mississippi River Basin of North America, invasive bigheaded carp (silver carp Hypophthalmichthys molitrix and bighead carp H. nobilis, also referred to as Asian carp) have spread rapidly over the past several decades. In the Illinois River, an important tributary of the Upper Mississippi River, reproduction appears to be sporadic and frequently unsuccessful, yet bigheaded carp densities...

Cyprinid herpesvirus 3 (CyHV-3) infects koi and common carp and causes widespread mortalities. While the virus is a significant concern for aquaculture operations in many countries, in Australia the virus may be a useful biocontrol agent for pest carp. However, carp immune responses to CyHV-3, and the molecular mechanisms underpinning resistance, are not well understood. Here we used RNA-Seq on...

Trypanosoma danilewskyi strain F Cc-1 was isolated from the blood of a laboratory infected juvenile common carp. Trypanosomes (blood stream forms) were first adapted to culture conditions in Tobie’s medium. Ten sterilized glass culture tubes each containing 2 ml of Tobie’s medium solidified in slants and covered with 1 ml Locke-Krebs overlay, were inoculated with 0.1 ml of infected blood contai...

BACKGROUND During the inflammatory process, chemokine CXCL8 plays a pivotal role in recruitment of human neutrophilic granulocytes. A diversity of sequences similar to CXCL8 was reported in fish, but their evolutionary relationships and functional homology with their human homolog remain unclear. PRINCIPAL FINDINGS We screened fish genomes to seek for sequences related to CXCL8. A first linea...

Goussia carpelli causes enteritic coccidiosis in juvenile carp. In nature it affects carp fry (1 to 2 mo old) and fish (3 to 4 mo old) which are subjected to environmental stress. Carp treated with corticosteroids or subjected to temperature stress in the laboratory produced higher numbers of oocysts during the primary infection. Resistance to reinfection via the fecal contamination route, howe...

A widespread grass carp hemorrhagic disease (GCHD) caused by grass carp reovirus (GCRV) has been known in China since 1983. A virulent reovirus strain, HZ08, was isolated from diseased grass carp in Zhejiang Province, China. We sequenced and analyzed the complete genome of strain HZ08 and compared it with published GCRV genome sequences, contributing to the evidence of several genotypes of GCRV...

BACKGROUND Rheumatoid factor (RF), anti-citrullinated protein antibodies (ACPA) and anti-carbamylated protein (anti-CarP) antibodies are rheumatoid arthritis (RA)-associated autoantibodies. Besides their presence in human serum, anti-CarP antibodies have also been described in rodent models of arthritis, while ACPA are not consistently detectable. Data on these RA-associated autoantibodies in p...
