Crystal structure of a dimeric oxidized form of human peroxiredoxin 5.

its reduced form. Here, a new crystal form of human peroxiredoxin 5 is described at 2.0 A resolution. The asymmetric unit contains three polypeptide chains. Surprisingly, beside two reduced chains, the ...

Virologic versus cytologic triage of women with equivocal Pap smears: a meta-analysis of the accuracy to detect high-grade intraepithelial neoplasia.

Pap smear. METHODS: Data were extracted from articles published between 1992 and 2002 that contained results of virologic and cytologic testing followed by colposcopically directed biopsy in women with an ...

Assessment of the clinical and virological protection provided by a commercial inactivated bovine viral diarrhoea virus genotype 1 vaccine against a BVDV genotype 2 challenge.

carried out to determine the cross-protective efficacy of a commercial inactivated vaccine containing a BVDV-1 strain. A group of five BVDV-free calves was vaccinated twice and a second group of five calves ...

Prevalence of human erythrovirus B19 DNA in healthy Belgian blood donors and correlation with specific antibodies against structural and non-structural viral proteins.

positive despite the presence of IgG antibodies), as suggested by their low viral loads (< 10(4) IU /ml). Fifteen out of 36 major pools contained one or more contaminated donations. Among these, 12 tested ...

Detection and characterization of verotoxigenic Escherichia coli by a VTEC/EHEC multiplex PCR in porcine faeces and pig carcass swabs36718

causes oedemic disease in young pigs, four strains contained the hlyA gene and 19 the eaeA gene. All strains isolated were further identified with an enterotoxigenic E. coli (ETEC) multiplex PCR developed ...

Optimization and validation of a micellar electrokinetic chromatographic method for the analysis of several angiotensin-II-receptor antagonists

parameters permitted the separation of the six ARA- II s, which was best carried out using a 55-mM sodium phosphate buffer solution (pH 6.5) containing 15 mM of sodium dodecyl sulfate. The same system can also ...

Mapping of murine Th1 helper T-Cell epitopes of mycolyl transferases Ag85A, Ag85B, and Ag85C from Mycobacterium tuberculosis.

peptides of the three Ag85 proteins, and the epitope repertoire was broader than in infected mice. Despite pronounced sequence homology, a number of immunodominant regions contained component specific ...

Tetraponera ants have gut symbionts related to nitrogen-fixing root-nodule bacteria.

examined the ultrastructure of these bacteria and have amplified, cloned and sequenced ribosomal RNA-encoding genes, showing that the ant pouch contains a series of close relatives of Flavobacteria and ...

Use of the pAL5000 replicon in PAH-degrading mycobacteria: application for strain labelling and promoter probing.

pyrene, respectively, were successfully electroporated with pAL5000-based plasmids containing the green fluorescent protein (gfp) gene of Aequoria victoria under the control of the hsp60 promoter of ...
