On-line solid-phase extraction with ultra performance liquid chromatography and tandem mass spectrometry for the detection of nicotine, cotinine and trans-3'-hydroxycotinine in urine to strengthen human biomonitoring and smoking cessation studies.
Pollution Abstract: At the time of writing, this work appears to be the first published report on the coupling of on-line solid phase extraction (SPE) with ultra performance liquid chromatography-tandem mass ...
Efficacy of chimeric Pestivirus vaccine candidates against classical swine fever: protection and DIVA characteristics.
a large vaccinated population. For Flc9 vaccinated pigs, the E2 ELISA performed very well, with an expected 0.04% false positive results in a large vaccinated population. Both CP7_E2alf and Flc9 are ...
Investigation into the genotoxicity of water extracts from Hypoxis species and a commercially available Hypoxis preparation.
p.350-6 (2013) Keywords: Comet Assay DNA Damage Humans Hypoxis Mutagenicity Tests Mutagens Plant Extracts Abstract: We performed an in vitro evaluation of the genotoxic potential of water extracts from four ...
Multiple HPV infections with high viral loads are associated with cervical lesions but do not differentiate grades of cervical abnormalities
999 consecutive BD-SurePath liquid-based cervical cytology samples enriched with additional ASC- US (n=100), LSIL (n=100) and HSIL (n=97). HPV genotyping was performed on cytology specimens only using ...
New SYBR®Green methods targeting promoter sequences used for screening of several GM events pending for authorisation in Europe
effective control on food and feed products. This need can be achieved by performing an intensive screening combined with decision support tools like the CoSYPS matrix which permits reducing the number of ...
The APTIMA HPV assay versus the Hybrid Capture 2 test in triage of women with ASC-US or LSIL cervical cytology: a meta-analysis of the diagnostic accuracy.
Capture 2 (HC2) test has consistently been shown to perform better in triage of women with cervical cytology results showing atypical squamous cells of undetermined significance (ASC- US) but often not in ...
What's in a strain? Viral metagenomics identifies genetic variation and contaminating circoviruses in laboratory isolates of pigeon paramyxovirus type 1.
genome sequences was performed. In addition to providing nearly complete paramyxovirus genome sequences, our sequence-independent approach identified the presence of pigeon circovirus (PiCV) sequences in ...
Serological and virological BVDV prevalence and risk factor analysis for herds to be BVDV seropositive in Belgian cattle herds.
Belgium, a cross-sectional study was performed between November 2009 and March 2010. Young stock aged between 6 and 12 months from 773 randomly selected Belgian cattle herds were tested for BVDV-specific ...
Bayesian estimation of the true prevalence, sensitivity and specificity of the Rose Bengal and indirect ELISA tests in the diagnosis of bovine brucellosis.
performance and discriminative ability. The objective of this study was to assess the performance of the Rose Bengal test (RBT) and an indirect ELISA (iELISA) in diagnosing brucellosis in 995 serum samples ...
Scientific opinion on the presence of dioxins (PCDD/Fs) and dioxin-like PCBs (DL-PCBs) in commercially available foods for infants and young children
to decrease the dietary exposure of infants and young children to dioxins and DL- PCB s. The CONTAMP anel did not perform an exposure or risk assessment, but evaluated whether the enforcement of the ...
