Advanced Science, EarlyView.DECENT is a deep learning method that enhances noninvasive preimplantation genetic testing by accurately reconstructing embryonic copy number variations (CNVs) from cell‐free DNA in spent embryo culture media. By mitigating maternal contamination, DECENT improves diagnostic accuracy, even with high contamination levels, offering a reliable, noninvasive

Future Fertility in Low Fertility Countries [PDF]
, 2014 Chapter 3 is the first of six that present a comprehensive science-based assessment of what we know today about the drivers of future fertility, mortality, migration, and education. This chapter concerns countries with currently low fertility. It presents and justifies assumptions for future fertility trajectories based on an overview of recent ...

Advanced Science, EarlyView.ACLY is vital for early embryo development. IGF‐1 activates AKT to phosphorylate ACLY, driving its nuclear localization and recruitment of HATs (P300/HAT1), boosting acetyl‐CoA production and histone acetylation for transcriptional activation. Conversely, ACLY deficiency (via knockdown, knockout, or AKT inhibition) reduces nuclear acetyl‐CoA, disrupts ...

Tempo-Adjusted Period Parity Progression Measures: [PDF]
In this paper we apply tempo-adjusted period parity progression ratios (Kohler and Ortega 2002) to Sweden, the Netherlands and Spain. These countries represent three distinct demographic patterns in contemporary Europe and are of particular interest for ...

Advanced Science, EarlyView.MYC is a transcription factor (TF) that binds DNA near transcriptional start sites (TSSs) and within enhancer elements. Here, unappreciated sites of MYC binding in the vicinity of transcriptional end sites (TESs) of many genes in multiple cell types in association with numerous other TFs are described previously.

The Fertility Transition Around the World - 1950-2005 [PDF]
In this paper we analyze the distribution of fertility rates across the world using parametric mixture models. We demonstrate the existence of twin peaks and the division of the world's countries in two distinct components: a high-fertility regime and a ...
