According to the results of FTS the women were categorised into three risk groups: low risk for aneuploidy (<1:300), intermediate risk (1:300-1:50) and high risk (>1:50). They were counselled about the available options for invasive prenatal testing (IPT) and NIPT available at the time of FTS. The nine months before and after the introduction of NIPT were evaluated regarding further

testing after FTS.\n\nRESULTS: In total, 951 women were included: 505 examinations (group 1) were carried out before NIPT became available, 446 (group 2) thereafter. In group 2, 9.0% (40/446) had NIPT. Here, 60.0% (24/40) had a low risk according to FTS. In group 2 there was an increase of 3.6% of additional prenatal tests after FTS. The greatest increase was noted in the intermediate-risk Proteases inhibitor category (10.7%). The number of invasive prenatal tests decreased by 67.4%.\n\nCONCLUSIONS: We observed a notable increase in prenatal testing after the implementation of NIPT. NIPT is an additional test for women who need more reassurance. Since the options for pregnant women become more complex this website and the costs of NIPT are high, prenatal counselling has become more challenging.”
“The extent to which mitochondrial

DNA (mtDNA) variation is involved in adaptive evolutionary change is currently being reevaluated. In particular, emerging evidence suggests that mtDNA genes coevolve with the nuclear genes with which they interact to form the energy producing enzyme complexes in the mitochondria. This suggests that intergenomic epistasis between mitochondrial and nuclear genes may affect whole-organism metabolic phenotypes. Here, we use crossed combinations of mitochondrial and nuclear lineages of the seed beetle Callosobruchus

maculatus and assay metabolic rate under two different temperature regimes. Metabolic rate was affected by an interaction between the mitochondrial and nuclear lineages and the temperature regime. Sequence data suggests that mitochondrial genetic variation has a role in determining the outcome of this interaction. Our genetic dissection of metabolic rate reveals a high level of complexity, encompassing genetic interactions over two genomes, and genotype x genotype x environment Wnt tumor interactions. The evolutionary implications of these results are twofold. First, because metabolic rate is at the root of life histories, our results provide insights into the complexity of life-history evolution in general, and thermal adaptation in particular. Second, our results suggest a mechanism that could contribute to the maintenance of nonneutral mtDNA polymorphism.”
“Analysis of fast chlorophyll fluorescence rise OJIP was carried out to assess the impact of diuron, paraquat and flazasulfuron on energy fluxes and driving forces for photosynthesis in Lemna minor. Results showed that diuron and paraquat treatment produced major changes in electron transport in active reaction centres (RCs).
