Improved Metrological Traceability of Particle Size Values Measured with Line-Start Incremental Centrifugal Liquid Sedimentation.

uncertainties were estimated according to the Guide to the Expression of Uncertainty in Measurement. The results indicate that the modal Stokes diameter and effective particle density that are assigned to the ...

Evaluation of 16 commercial antibody ELISAs for the detection of bovine viral diarrhea virus-specific antibodies in serum and milk using well-characterized sample panels.

animals included in the panel. AS e was also better for iELISAs; DS p was >95% for all but 2 ELISA s. Repeatability, expressed as coefficients of variation (CV) of optical densities, was generally good, ...

Characterization of two recombinant HVT-IBD vaccines by VP2 insert detection and cell-mediated immunity after vaccination of specific pathogen-free chickens.

and more effective vaccination approaches, including the use of the recombinant turkey herpesvirus vaccine expressing the immunogenic structural VP2 protein of IBDV (recombinant HVT (rHVT)- IBD). The ...

Zona pellucida gene mRNA expression in human oocytes is related to oocyte maturity, zona inner layer retardance and fertilization competence.

p.292-303 (2017) Abstract: STUDY QUESTION: Do the mRNA expression levels of zona pellucida (ZP) genes, ZP1, 2, 3 and 4 in oocyte and cumulus cells (CC) reveal relevant information on the oocyte? SUMMARY ...

The role of methylation, DNA polymorphisms and microRNAs on HLA-G expression in human embryonic stem cells.

p.118-127 (2017) Abstract: The human leukocyte antigen (HLA)-G gene seems to play a pivotal role in maternal tolerance to the fetus. Little is known about HLA-G expression and its molecular control during in ...

Brain Stem Cytokines DNA, Viral Female Gene Expression Herpesvirus 1, Suid Olfactory Bulb Pseudorabies Swine Swine Diseases Trigeminal Ganglion virulence Abstract: The severity of clinical symptoms ...

Letter to the editor: New metrics to monitor progress towards global HIV targets: using the estimated number of undiagnosed HIV-infected individuals as denominator.

testing programmes when it is compared with the yearly number of new diagnoses. This comparison may be expressed as the ratio of yearly number of new diagnoses to the estimated number of undiagnosed ...

DLL4 expression is a prognostic marker and may predict gemcitabine benefit in resected pancreatic cancer.

potential therapeutic target to improve outcome for patients with pancreatic ductal adenocarcinoma (PDAC). METHODS: Using immunohistochemistry (IHC) and tissue microarray (TMA), we assessed the expression ...

Cost-effectiveness analysis in melanoma detection: A transition model applied to dermoscopy.

Effectiveness was expressed in quality-adjusted life years (QALY s), a composite measure depending on melanoma-related morbidity and mortality. Costs included costs of treatment and follow-up as well as costs of ...
