Diseases associated with point mutations in the mitochondrial DNA (mtDNA) are maternally inherited. We evaluated whether pre-implantation genetic diagnosis, based on polar body mutation load detection could be used to distinguish healthy from affected oocytes. Restriction Fragment Length Polymorphism (RFLP) analysis was used and validated, to determine(More)
Retinoblastoma is a pediatric eye tumor in which bi-allelic inactivation of the Retinoblastoma 1 (RB1) gene is the initiating genetic lesion. Although recently curative rates of retinoblastoma have increased, there are at this time no molecular targeted therapies available. This is, in part, due to the lack of highly penetrant and rapid retinoblastoma(More)
CONTEXT Hashimoto's thyroiditis (HT) and Graves' disease (GD), two autoimmune thyroid diseases (AITD), occur more frequently in women than in men and show an increased incidence in the years following parturition. Persisting fetal cells could play a role in the development of these diseases. OBJECTIVE Aim of this study was to detect and characterize fetal(More)
The (non)differentiation status of human embryonic stem cells (hESCs) is usually analyzed by determination of key pluripotency defining markers (e.g., OCT4, Nanog, SOX2) by means of reverse transcription quantitative polymerase chain reaction (RT-qPCR), flow cytometry (FC), and immunostaining. Despite proven usefulness of these techniques, their destructive(More)
Cell nuclei detection in fluorescent microscopic images is an important and time consuming task in a wide range of biological applications. Blur, clutter, bleed through and partial occlusion of nuclei make individual nuclei detection a challenging task for automated image analysis. This paper proposes a novel and robust detection method based on the active(More)
Velkeniers B, et al. Fetal microchimeric cells in blood of women with an autoimmune thyroid disease. P ersistence of fetal microchimeric cells may result in the development of autoimmune thyroid diseases (AITD) such as Hashimoto thyroiditis (HT) or Graves disease (GD). In women, HT and GD show an increased incidence in the years following parturition.(More)
Autoimmune thyroid diseases (AITD) show a female predominance, with an increased incidence in the years following parturition. Fetal microchimerism has been suggested to play a role in the pathogenesis of AITD. However, only the presence of fetal microchimeric cells in blood and in the thyroid gland of these patients has been proven, but not an actual(More)
Autoimmune thyroid diseases (AITD) are the most prevalent autoimmune disorders affecting up to 5% of the general population. The two most common forms of AITD are Graves disease (GD) and Hashimoto's thyroiditis (HT). Although HT and GD are multifactorial diseases where genes and environmental factors influence the onset and development of the disease, 3(More)
