BACKGROUND Dystonia is a heterogenous group of movement disorders whose clinical spectrum is very wide. At least 13 different genes and gene loci have been reported. While a 3-bp deletion in the DYT1 gene is the most frequent cause of early limb-onset, generalized dystonia, it has also been found in non-generalized forms of sporadic dystonia. An 18-bp(More)
In this paper, we propose a new alternative blind SR to estimate motion, blurring, and higher resolution (HR) image alternatively and iteratively in case the three are all unknown. The related ternary optimization is first divided into two alternate and iterative optimizations, in which the unitary one is about motion estimation and the dualistic one is(More)
Document image binarization is the basis of Optical Character Recognition (OCR). For B.Gatos' adaptive binarization method exists the shortcomings, we propose an improved adaptive document image binarization method which consists of four steps. The first step is dedicated to a denoising procedure using a low-pass Wiener filter based on local statistics. In(More)
Manchurian ash (Fraxinus mandshurica Rupr.) is a valuable hardwood species in Northeast China. In cultures of F. mandshurica, somatic embryos were produced mainly on browned explants. Therefore, we studied the mechanism of explant browning and its relationship with somatic embryogenesis (SE). We used explants derived from F. mandshurica immature zygotic(More)
We developed a shoot multiplication protocol for Syringa reticulata Blume var. mandshurica Hara from in vitro cultured seedlings that derived from in vitro germinated seeds. The shoots could be induced on Murashige and Skoog (MS) medium with proper plant growth regulator combinations of 6-benzylaminopurine (BA) and indole-3-butyric acid (IBA). The better(More)
Korean pine (Pinus koraiensis Sieb. et Zucc.) is an ecologically and economically important tree species in East Asia. Molecular studies of seed development of this species are limited due to the lack of effective RNA extraction protocols. This study aimed to obtain an effective method to extract high-quality RNA from Korean pine seeds. The TRIzol kit and(More)
