It has been shown that mutations in the SLC26A4 gene are involved in syndromic deafness characterized by congenital sensorineural hearing impairment and goitre (Pendred's syndrome), as well as in congenital isolated deafness (DFNB4), both of which are associated with enlarged vestibular aqueduct (EVA). The prevalence of SLC26A4 mutations in Pendred's(More)
Creating high-quality multimedia presentations requires much skill, time, and effort. This is particularly true when temporal media, such as speech and animation, are involved. We describe the design and implementation of a knowledge-based system that generates customized temporal multimedia presentations. We provide an overview of the system’s(More)
Waardenburg syndrome (WS) is a rare disorder characterized by distinctive facial features, pigment disturbances, and sensorineural deafness. There are four WS subtypes. WS1 is mostly caused by PAX3 mutations, while MITF, SNAI2, and SOX10 mutations are associated with WS2. More than 100 different disease-causing mutations have been reported in many ethnic(More)
OBJECTIVE We examined whether implantation of autologous bone marrow mononuclear cells (BM-MNC) can augment neovascularization and bone regeneration in steroid-induced osteonecrosis of the femoral head. METHODS Sixty-five 28-week-old male New Zealand white rabbits were divided into group I (left untreated, N=20), group II (core decompression, N=20) and(More)
Dicer cleaves double-stranded RNAs (dsRNAs) or precursor microRNAs (pre-miRNAs) to yield ≈ 22-nt RNA duplexes. The pre-miRNA structure requirement for human Dicer activity is incompletely understood. By large-scale in vitro dicing assays and mutagenesis studies, we showed that human Dicer cleaves most, although not all, of the 161 tested human pre-miRNAs(More)
microRNAs (miRNAs) are a large family of approximately 22-nucleotide-long RNAs that regulate gene expression. They are first transcribed as long, primary transcripts, which then undergo a series of processing steps to generate the single-stranded, mature miRNAs. Here, we showed that Drosha cleaved hundreds of human primary miRNA transcript substrates with(More)
iNOS plays an important role in mediating inflammation. In this study, we found that iNOS-derived NO was increased 2.4-fold in the serum samples of 101 patients infected with influenza A virus in comparison with samples of 105 healthy individuals. In A549 human lung epithelial cells, infection with influenza A virus or stimulation with poly(I:C)+IFN-gamma(More)
Chordomas are primary malignant tumors of the notochord that are resistant to conventional chemotherapy. Expression of programmed cell death ligand 1 (PD-L1), prevalence of tumor-infiltrating lymphocytes (TILs), and their clinical relevance in chordoma remain unknown. We evaluated PD-L1 expression in three chordoma cell lines and nine chordoma tissue(More)
