Chromosomal aneuploidy is a main cause of human prenatal and postnatal morbidity and mortality, and the most frequent genetic cause of mental retardation. Prenatal testing for trisomies is available to women of advanced maternal age, with ultrasound findings consistent with Down syndrome or with previous fetuses with chromosomal abnormalities. Currently, fetal genetic material is collected through procedures such as amniocentesis and chorionic villous sampling to enable the definitive diagnosis of fetal genetic diseases. These invasive procedures are associated with the risk of fetal loss. <br><br> <strong>Technology</strong><br> The invention relates to non-invasive methods for determining the genetic status of a fetus. Chromosomal aberrations such as fetal aneuploidy, in particular Trisomy 21 (T21) or also known as Down syndrome (DS), may be diagnosed from mother`s blood via evaluation of differential expression of microRNAs (miRNAs).<br><br>

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
In the cells of higher organisms, organelles such as the nucleus or mitochondria perform a range of complex functions necessary for life. In the networks of...

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.
When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...
