— The detection of direct causality, as opposed to indirect causality, is an important and challenging problem in root cause and hazard propagation analysis. Several methods provide effective solutions to this problem when linear relationships between variables are involved. For nonlinear relationships, currently only overall causality analysis can be(More)
Cell differentiation involves widespread epigenetic reprogramming, including modulation of DNA methylation patterns. The differentiation potential differences in DNA methylation patterns might function in pluripotency restriction, while tissue-specific differences might work in lineage restriction. To investigate the effects of neuronal induction on(More)
OBJECTIVE To investigate the modulation of microRNAs (miRNAs) upon the neuronal differentiation of mesenchymal stem cells (MSCs) through targeting RE-1 Silencing Factor (REST), a mature neuronal gene suppressor in neuronal and un-neuronal cells. METHODS Rat bone marrow derived-MSCs were induced into neuron-like cells (MSC-NCs) by DMSO and BHA in vitro.(More)
Small-diameter (<4 mm) vascular constructs are urgently needed for patients requiring replacement of their peripheral vessels. However, successful development of constructs remains a significant challenge. In this study, we successfully developed small-diameter vascular constructs with high patency using our integrally designed computer-controlled(More)
While many studies have examined the pregnancy and health-related outcomes of delayed motherhood for women, less is known concerning the potential consequences for their children. This study aims to investigate the effect of delayed motherhood on the hippocampus at the whole genome level. Sprague–Dawley rat females, either at the age of 3 or 12 months, were(More)
PURPOSE The literatures show that photodynamic therapy (PDT) and intravitreal ranibizumab (IVR) have their own specific advantages in treating polypoidal choroidal vasculopathy (PCV). Using a meta-analysis, we want to provide some suggestions for the clinical application of the two treatments to PCV patients through a comparison of the functional outcomes(More)
— Detection of causality is an important and challenging problem in root cause and hazard propagation analysis. A new information theory-based measure, transfer 0-entropy, is proposed for causality analysis on the basis of the definitions of 0-entropy and 0-information without assuming a probability space. For the cases of more than two variables, a direct(More)
BACKGROUND Recent studies showed that inappropriate expression of microRNAs (miRNAs) is strongly associated with tumor-related processes in humans (2-9,11-17). OBJECTIVE To understand the changes of miRNAs in endometriosis. MATERIALS AND METHODS With real-time RT-PCR, we investigated the miR-143 and miR-145 expression in eutopic (EU, n=2) and ectopic(More)
