The main goal of the NA48 experiments at the CERN SPS has been the search for direct CP violation (CPV) in kaon decays. In this paper results from NA48 and NA48/2 are presented. The direct CPV parameter Re(ε′/ε) has been measured by NA48 from the decay rates of neutral kaons into two pions: combining the results from data collected in 1997, 98, 99 and 2001, an overall value of Re(ε′/ε) = (14.7 ...

Concerns about the changing environment and fossil fuel depletion have prompted much controversy and scrutiny. One way to address these issues is to use concentrating photovoltaics (CPV) as an alternate source for energy production. Multijunction solar cells built from III–V semiconductors are being evaluated globally in CPV systems designed to supplement electricity generation for utility comp...

Canine parvovirus (CPV) appears to be endemic in almost all populations of wild and domesticated dogs. It causes serious contagious enteric disease. The VP2 protein of CPV is a major capsid protein and plays an important role in the host immune response. In the present study, the recombinant VP2 was expressed in Escherichia coli (E. coli) using the pBAD expression system. Virus DNA from the inf...

The VP2 structural protein of parvovirus can produce virus-like particles (VLPs) by a self-assembly process in vitro, making VLPs attractive vaccine candidates. In this study, the VP2 protein of canine parvovirus (CPV) was expressed using a baculovirus expression system and assembled into parvovirus-like particles in insect cells and pupae. Electron micrographs of VLPs showed that they were ver...

The study reported here investigated the efficacy of two commonly used modified-live virus vaccines to induce seroconversion against canine parvovirus (CPV) in 213 Rottweiler and Doberman pinscher pups with various titers of maternally derived CPV antibody. Beginning at 6 to 8 weeks of age, pups were given a subcutaneous vaccination every 21 days (range, 18-24 days) in the dorsal region of the ...

Background: The importance of viral protein-2 (VP2) of canine parvovirus (CPV) in binding to human cancer cells, production of veterinary vaccines and diagnostic kits has motivated several researches on producing this protein.Objectives: Our purpose was to construct recombinant bacmid shuttle vectors expressing VP2 of CPV using Bac-to-Bac baculoviral expr...

The canine parvovirus (CPV) empty-capsid structure has been determined and refined to 3.0 A resolution in the tetragonal space group P4(3)2(1)2 with cell dimensions a = b = 254.5 and c = 795.0 A. The successful structure determination shows that reasonably good diffraction data were obtained in spite of the very long c axis. The structure was solved by molecular replacement using the electron d...

Canine papillomaviruses (CPVs) have been identified in various benign and malignant neoplastic skin disorders. The most frequent manifestations of CPV infections are classical warts and pigmented plaques. Although the etiology of canine oral papillomatosis is well established, knowledge about CPVs role in the development of pigmented plaques remains vague. Indeed, as CPV DNA may frequently be f...

Abstract: Finding CP violation (CPV) in 1964 produced a real revolution in the fundamental dynamics, although the community did not understand it right away. The paper by Kobayashi & Maskawa [1] appeared in 1973 to describe CPV in classes of three (or more) families of quarks, non-minimal Higgs' dynamics and/or charged right-handed currents. The Standard Model is now with three families of quar...

The protective effect of immunoglobulins derived from chicken egg yolk (IgY) against infection by Canine parvovirus 2 (CPV-2) was evaluated in 10 beagle dogs orally challenged with a strain of the virus. The 2-mo-old dogs were divided into 3 groups and treated with powders containing CPV-2 IgY or normal egg yolk for 7 d after the challenge. The 4 dogs receiving normal egg yolk (control group) d...
