Researchers in our laboratory have previously shown that ghrelin, a gastric peptide hormone, may regulate mesenchymal cell differentiation into adipocytes and myocytes. Here we show that ghrelin promotes osteogenesis of intramembranous bone and improves the repair of calvarial bone defects in rats. Rats with a 9 mm full-thickness calvarial bone defect(More)
Much research has focused on developing vascular endothelial growth factor (VEGF) delivery systems to enhance angiogenesis in wound repair and in tissue engineering. Collagen can be used as a delivery system because of its biocompatibility, but its fast degradation rate and limited affinity with growth factors are disadvantageous for maintaining a(More)
In RNA-Seq studies, there are still many challenges for reliably assembling transcripts. Both genome-guided and de novo methods always produce too many false transcripts because of known and unknown factors. Therefore, the postassembly quality filtering is necessary before performing downstream analyses. Here, we present an automatic and efficient tool of(More)
Due to the phenotype-based artificial selection in domestic cattle, the underlying functional genes may be indirectly selected and show decreasing diversity in theory. The growth hormone receptor (GHR) gene has been widely proposed to significantly associate with critical economic traits in cattle. In the present study, we comparatively studied the genetic(More)
PURPOSE The aim of this 1-year prospective study was to evaluate, in patients with severe periodontitis, the clinical performance of implants placed immediately after extraction of remaining teeth or in healed sockets and immediately loaded for prosthetic oral rehabilitation, and to compare the clinical outcomes for implants placed in fresh extraction(More)
It is widely acknowledged that transcriptional diversity largely contributes to biological regulation in eukaryotes. Since the advent of second-generation sequencing technologies, a large number of RNA sequencing studies have considerably improved our understanding of transcriptome complexity. However, it still remains a huge challenge for obtaining(More)
The transcript assembly is essential for transcriptome studies trom next-generation sequencing data. However, there are still many faults of algorithms in the present assemblers, which should be largely improved in the future. According to the requirement of reference genome or not, the transcript assembly could be classified into the genome-guided and de(More)
There has been considerable focus in investigations on the delivery systems and clinical applications of bone morphogenetic protein‑2 (BMP‑2) for novel bone formation. However, current delivery systems require high levels of BMP‑2 to exert a biological function. There are several concerns in using of high levels of BMP‑2, including safety and the high cost(More)
Collagen scaffolds are frequently employed for applications in regenerative medicine. In previous studies, we affirmed that Traut's reagent (2-Iminothiolane hydrochloride) and Sulfo-SMCC (4-(N-Maleimidomethyl) cyclohexane-1-carboxylic acid 3-sulpho-N-hydroxysuccinimide ester sodium salt) could covalently bind growth factors on collagen scaffolds. We also(More)
PURPOSE Intrasinus new bone formation (BF) has been observed after no-grafting osteotome sinus augmentation, and it is hypothesized to be influenced by the dimensions of the maxillary sinus. The aim of this clinical trial is to evaluate the influence of lateral-medial sinus width (SW) on no-grafting osteotome sinus augmentation outcomes using cone-beam(More)
