There is limited evaluation of the impact of reducing unhelpful perfectionism in adolescents but no evaluation in children. The aim of the current pilot study was to investigate whether perfectionism could be manipulated in children aged 10-12 years. C...

Genetically different Atlantic herring Clupea harengus spawning waves

Putative spawning waves of Atlantic herring Clupea harengus were collected from 4 locations and genetically compared using 9 microsatellite loci. Shelf-scale (100s km) spatial differences were measured (max FST = 0.01, p < 0.001) and 1 sub-annual temporal difference (FST = 0.0058, p = 0.001) was revealed between spawning fish (predominantly comprising the same year-class) collected, 6 d apart, ...

I-4: Is It Time Now to Cancel Fresh EmbryoTransfer

The implantation of embryo depends on the quality of the embryo and the receptivity of the endometrium. While the factors affecting embryo quality were optimized, the implantation rates did not reach the desirable levels. This directs the blaming for endometrial receptivity which already has been affected by supra-physiological levels of hormone, namely estradiol, in controlled ovarian hypersti...
