PURPOSE To test the association of the X-chromosome regions (Xp21.1-q21.2 and Xq25-27.2) with Leber hereditary optic neuropathy (LHON) in Chinese patients. METHODS One hundred and seventy-five male LHON patients with the G11778A mutation and 100 unrelated normal males participated. Twelve microsatellite markers and four single-nucleotide polymorphisms(More)
In this paper, we propose a method combining visual local features and depth image information to recognize cooking gestures. We employ the feature calculation method[2] which used extended FAST detector and a compact descriptor CHOG3D to calculate visual local features. We pack the local features by BoW in frame sequences to represent the cooking gestures.(More)
Cognitive radio (CR) is a typical technology to allow secondary users use the licensed spectrum resource dynamically. Spectrum sensing is one of the important technics in CR. In this paper, optimal threshold for dual-stage spectrum sensing is researched. Two-threshold energy detection (ED) and one-threshold cyclostationary feature detection (CFD) are chosen(More)
PURPOSE Hepatoma-derived growth factor (HDGF) is a mitogen that promotes endothelial proliferation and neuronal survival. Using a unique technology of ligandomics, we recently identified HDGF as a retinal endothelial binding protein. The purpose of this study is to examine the role of HDGF in regulating ocular vasculature and the expression of HDGF in the(More)
Leucine zipper-EF-hand-containing transmembrane protein1 (LETM1) is located in the mitochondrial inner membrane and is defective in Wolf-Hirschhorn syndrome. LETM1 contains only one transmembrane helix, but it behaves as a putative transporter. Our data shows that LETM1 knockdown or overexpression robustly increases or decreases mitochondrial Ca(2+) level(More)
