Pregnancy outcome after cervical conisation: A 2nd retrospective cohort study in the Leuven University Hospital.
Abstract: OBJECTIVE: To evaluate whether the dimensions of the cones removed during large loop excision of the transformation zone have decreased over time. Secondly, whether these changes were associated ...
Hepatitis E virus serology and PCR: does the methodology matter?
(Altona RealStar®), and two optimized in-house real-time RT- PCR assays (according to Jothikumar et al., 2006 and Gyarmati et al., 2007). In addition, all three PCR assays were performed on 16 external ...
Migrant's access to preventive health services in five EU countries.
non- EU countries, were found to have poorer access to PHS s. The overall risk of not reporting a screening test or a flu vaccination ranged from a minimum of 1.8 times (colorectal cancer screening), to ...
Improved Metrological Traceability of Particle Size Values Measured with Line-Start Incremental Centrifugal Liquid Sedimentation.
Because several of the input quantities of the Stokes equation cannot be easily determined for this case of a rotating disc, the disc- CLS approach relies on calibrating the sedimentation time scale with ...
Influence of apixaban on commonly used coagulation assays: results from the Belgian national External Quality Assessment Scheme.
a survey to assess the effect of the direct oral anticoagulant apixaban on the coagulation assays prothrombin time (PT), activated partial thromboplastin time (aPTT), fibrinogen and antithrombin as performed ...
Laboratory validation of two real-time RT-PCR methods with 5'-tailed primers for an enhanced detection of foot-and-mouth disease virus.
and Specificity Sheep Swine Abstract: The 3D and 5UTR real-time RT- PCR assays (RT-qPCR) from Callahan et al. (2002) and Reid et al. (2002) are commonly used reference methods for the detection of ...
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.
2 panels of well-characterized serum and milk samples. Sixteen ELISA s from 9 different manufacturers, available on the Belgian market at the time of our study, were assessed for their diagnostic and ...
Brucella abortus is Prevalent in Both Humans and Animals in Bangladesh.
human sera and all animal samples were screened by Brucella genus-specific real-time PCR (RT- PCR), and positive samples were then tested by IS711 RT- PCR to detect B. abortus and B. melitensis DNA. Only ...
Specific antibody-mediated immunity in the reproductive tract of laying chickens immunized against Newcastle disease with conventional attenuated and inactivated vaccines.
and poor shell quality. Few published studies investigated local NDV-specific immune response in the reproductive tract after ND vaccination of hens. The present study investigated, for the first time ...
Augmented and doubly robust G-estimation of causal effects under a Structural nested failure time model.
Publication Type: Peer reviewed scientific article Authors: Karl Mertens; Vansteelandt, Stijn Source: Biometrics (2017) Abstract: Structural nested failure time models (SNFTM s) are models for the ...
