We previously found that mesenchymal stem cells (MSCs) derived from human-induced pluripotent stem cells (iPSCs) exerted immunomodulatory effects on Th2-mediated allergic rhinitis in vitro. However, their contribution to the asthma and allergic rhinitis in animal models remains unclear. In this study, we developed a mouse model of ovalbumin (OVA)-induced(More)
We report an unusual malignant tumour affecting an unusual site. Epithelioid haemangioendothelioma was formerly considered a tumour of intermediate malignancy but has been reclassified as fully malignant. It is important to be aware of this clinical entity as the best hope of cure is timely radical resection. There is a paucity of evidence concerning the(More)
Chondroblastoma of the temporal bone is a rare condition. Chondroblastomas account for less than 1% of primary bone tumors, and those involving the temporal bone represent a tiny fraction of these tumors with most arising from the knee, rib, and pelvis. We present a case series of two patients who presented with chondroblastomas of the temporal bone over a(More)
Results of past studies on the quality problems of LPC speech are reviewed. The causes of the quality problems are found to lie within the basic model assumptions as well as inaccuracies in LPC analysis and errors introduced in pitch and voicing detection and pa rameter quanti zation. Experiments discussed here show that LPC synthesis is generally very(More)
