To evaluate the failure rate and performance of cell-free DNA (cfDNA) testing, mainly in terms of detection rates for trisomy 21, performed by 2 laboratories using different analytical methods.
This article was published in the following journal.
Name: Fetal diagnosis and therapy
This study was undertaken to evaluate a novel method for stabilizing and preserving the original proportion of cell-free fetal DNA (cffDNA) in maternal blood for extended periods of time without using...
Telomere length at birth sets the baseline for telomere shortening and may influence adult disease risk like cancer. Telomere length is heritable, but may also be a marker of exposures in utero, inclu...
Fetal-maternal hemorrhage (FMH) occurs when fetal red blood cells (RBC) pass into the maternal circulation as a result of obstetric- or trauma-related complications to pregnancy. Their detection in th...
Cord blood (CB) is an alternative stem cell source for allogeneic haematopoietic stem cell transplantation (HSCT). The unique advantages with CB as a stem cell source lies in a degree of permissibilit...
Studies have examined the association between parental body mass index (BMI) and autism spectrum disorder (ASD) in offspring, with inconsistent results, especially regarding maternal obesity, overweig...
Combined first-trimester screening represents the gold standard of risk assessment for the presence of trisomy 21, 18, and 13. The concept is based on the age risk, the measurement of feta...
The purpose of this study is to determine whether, in a high risk population (placenta praevia and previous caesarean or prenatal suspicion of morbidly adherent placenta (MAP)), the concen...
This is a multi-centre prospective study in which blood samples will be taken from 1500 male patients aged between 21-80 scheduled for prostate biopsy. Analysis of cell-free cancer DNA ext...
In January 2007, the American Congress of Obstetricians and Gynecologists (ACOG) revised its guidelines that now recommend physicians are ethically obligated to fully inform all pregnant w...
Cell free fetal DNA might predict abnormal placental invasion
A principle of estimation in which the estimates of a set of parameters in a statistical model are those quantities minimizing the sum of squared differences between the observed values of a dependent variable and the values predicted by the model.
Meta-analysis of randomized trials in which estimates of comparative treatment effects are visualized and interpreted from a network of interventions that may or may not have been evaluated directly against each other. Common considerations in network meta-analysis include conceptual and statistical heterogeneity and incoherence.
A fractionated cell extract that maintains a biological function. A subcellular fraction isolated by ultracentrifugation or other separation techniques must first be isolated so that a process can be studied free from all of the complex side reactions that occur in a cell. The cell-free system is therefore widely used in cell biology. (From Alberts et al., Molecular Biology of the Cell, 2d ed, p166)
Separation of one or more kinds of cells from whole blood with the return of other blood cell constituents to the patient or donor. This is accomplished with an instrument that uses centrifugation to separate the cells into different layers based on the differences in cell density (displacement) or drag coefficients in a current (elutriation). The procedure is commonly used in adoptive transfer to isolate NK cells, lymphocytes, or monocytes.
Reduction of blood viscosity usually by the addition of cell free solutions. Used clinically (1) in states of impaired microcirculation, (2) for replacement of intraoperative blood loss without homologous blood transfusion, and (3) in cardiopulmonary bypass and hypothermia.
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
