PURPOSE To evaluate the epigenetic risk linked to assisted reproductive technology (ART) at single-embryo level by analyzing the methylation status of imprinted H19, PEG1, and KvDMR1 in human preimplantation embryos. METHODS A total of 254 human day 3 embryos produced by ART procedures were collected. All embryos were normally fertilized but unsuitable for transfer or freezing due to poor qua...
Dynamic mass redistribution (DMR) represents a novel, label-free, biosensor technology promising to translate GPCR signaling into complex optical “fingerprints” in real time and living cells. Herein, we present a strategy to frame cellular mechanisms that define label-free responses and compare DMR technology with traditional second messenger assays currently state of the art in GPCR drug disco...
CTG repeat expansion in DMPK, the cause of myotonic dystrophy type 1 (DM1), frequently results in hypermethylation and reduced SIX5 expression. The contribution of hypermethylation to disease pathogenesis and the precise mechanism by which SIX5 expression is reduced are unknown. Using 14 different DM1-affected human embryonic stem cell (hESC) lines, we characterized a differentially methylated ...
BACKGROUND Countries worldwide recommend women planning pregnancy to use daily 400 microg of synthetic folic acid in the periconceptional period to prevent birth defects in children. The underlying mechanisms of this preventive effect are not clear, however, epigenetic modulation of growth processes by folic acid is hypothesized. Here, we investigated whether periconceptional maternal folic aci...
BACKGROUND Recent studies have revealed relative frequency and characteristic phenotype of two major causative factors for Silver-Russell syndrome (SRS), i.e. epimutation of the H19-differentially methylated region (DMR) and uniparental maternal disomy 7 (upd(7)mat), as well as multilocus methylation abnormalities and positive correlation between methylation index and body and placental sizes i...
This article presents a brief overview of label-free optical biosensor-based cell assay technologies. Theoretical analysis suggests that a resonant waveguide grating (RWG) biosensor detects ligand-induced dynamic mass redistribution (DMR) within the bottom portion of an adherent cell layer. Pharmacological studies suggest that the DMR signal can serve as a novel physiological readout for monito...
خسارت‌هایی که دارواش‌های پاکوتاه به جنگل‌های سوزنی‌برگ و صنعتی جهان وارد آورده‌اند، محققان سراسر دنیا را بر آن داشته تا روش‌هایی برای ارزیابی شدت آلودگی و به تصویر کشیدن پراکنش مکانی و فضایی دارواش‌ها جهت مدیریت جنگل، حفظ حیات وحش و تنوع زیستی و افزایش دقت مطالعات دارواش ایجاد کنند. دو روش بررسی شدت آلودگی DMR و BVRکه از متداول‌ترین روش‌های مطالعه ابتلا به دارواش در جهان است و نسبت به سایر روش...
Emerging cyber-physical systems (CPSs), such as in the domains of automotive, robotics, and industrial automation, often run complex functions with different criticality levels on a heterogeneous distributed architecture. The ever stronger interactions between cyber components physical environment lead to dynamic irregular release these functions. This article investigates scheduling mixed-crit...
In this article, an end-to-end system was proposed for the challenge task of disease named entity recognition (DNER) and chemical-induced disease (CID) relation extraction in BioCreative V, where DNER includes disease mention recognition (DMR) and normalization (DN). Evaluation on the challenge corpus showed that our system achieved the highest F1-scores 86.93% on DMR, 84.11% on DN, 43.04% on C...
