Cell-Free Fetal DNA and Non-Invasive Prenatal Diagnosis of Chromosomopathies and Pediatric Monogenic Diseases: A Critical Appraisal and Medicolegal R…
2022
Cell-free fetal DNA (cffDNA) analysis is a non-invasive prenatal diagnostic test with a fundamental role for the screening of chromosomic or monogenic pathologies of the fetus. Its administration is performed by fetal DNA detection in the mother’s blood from the fourth week of gestation. Given the great interest regarding its validation as a diagnostic tool, the authors have set out to undertake a critical appraisal based on a wide-ranging narrative review of 45 total studies centered around such techniques. Both chromosomopathies and monogenic diseases were taken into account and systematically discussed and elucidated. Not surprisingly, cell-free fetal DNA analysis for screening purposes …
Living on the edge: Meoneura obscurella in the ‘Wieliczka’ Salt Mine (southern Poland) exhibits the first case of lecithotrophic ovoviviparity in the…
2021
During the studies on the invertebrate fauna of the subterranean part of the “Wieliczka” Salt Mine in Wieliczka, Poland, the presence of many specimens of the dipteran species Meoneura obscurella (Fallén 1823) was observed. Organic remains and faeces related to the presence of mice (Mus musculus) were indicated as a potential food source for the insects. M. obscurella displays lecithotrophic viviparity (ovoviviparity), which has developed due to extremely harsh abiotic conditions and a lack of food. This is the first documented case of lecithotrophic viviparity within the fly family Carnidae. Based on the ability of this species to inhabit and reproduce in the conditions of the subterranean…
The identity of the tropical African
2016
Abstract Polichne mukonja Griffini, 1908 from Cameroon was hitherto known only from the holotype preserved at the Royal Belgian Institute of Natural Sciences, Brussels. This was probably due to the fact that the genus Polichne Stål, 1874 distributed only in Australia and Papua New Guinea. In view of this distribution, the tropical African species was therefore overlooked in the African literature. The recent discovery of two specimens at the Naturhistorisches Museum, Vienna, now provides us with a better understanding of the identity of this taxon, which is related to the African genus Catoptropteryx Karsch, 1890. Polichne mukonja is here transferred to a new genus Griffinipteryx and both t…
