This study aimed to explore brain activation in patients with cleft lip and palate (CLP) using a Chinese character subvocalization task, which the stimuli were selected from clinical articulation evaluation test. CLP is congenital disability. Individuals usually have disorder caused by abnormal structure. Previous studies showed that primary somatosensory motor areas had significant difference CLP. However, whether was restored normal level after palatoplasty speech rehabilitation not clear....

Human alveolar bone-derived mesenchymal stem cells (hABMSCs) are promising candidates for bone therapies, which have the capacity to differentiate into osteoblasts. Recently, secretion of inducible cytokines and growth factors from (MSCs) has been discovered, we also reported osteogenic effects cell physical stimulation. In this study, investigated hABMSCs-conditioned media (B-CSM) on differentiation hABMSCs in vitro. Furthermore, analyzed B-CSM by proteomics array identify facilitate...

Non-syndromic cleft lip with or without palate (NSCL/P) is a common craniofacial birth defect. Growing evidence has demonstrated the competing endogenous RNA (ceRNA) hypothesis played role in pathogenesis of NSCL/P. Here, we identified important lncRNAs NSCL/P and constructed ceRNA regulatory network to predict their underlying functional mechanism.Total isolated from peripheral blood samples were analyzed by Human Clariom D Affymetrix platform differentially expressed genes (DEGs)...

Nonsyndromic cleft lip with or without palate (NSCL/P) represents a complex condition caused by genetic and environmental factors. The aim of this study was to investigate the relationship between EPHA3 polymorphisms NSCL/P.To five single nucleotide (SNPs) NSCL/P, we selected 180 affected patients 167 normal controls from Chinese Han Population. SNPs (rs7650466, rs1398197, rs17801309, rs1054750, rs7632427) were genotyped using SNaPshot technique; bioinformatic analyses performed determine if...

Non-syndromic clefts of the lip and/or palate (NSCLP) is most common congenital anomaly in craniofacial region. NSCLP a highly gene-associated malformation. We speculate that pregnant women with fetuses (pregnancies NSCLP) may have specific brain changes during pregnancy. To explore characteristic function pregnancies NSCLP, we analyzed resting-state MRI (rs-MRI) data forty-two (21 and 21 normal fetuses) to compare intergroup differences (fractional) amplitude low frequency fluctuations...
