BACKGROUND Accumulating evidence has shown that chronic cerebral ischemia (CCI) is one of the major causes of vascular dementia (VD) characterized by dysregulated cholesterol homeostasis and lipoprotein disturbances. Positive value of lipid-lowering agents has been widely evaluated for the treatment of VD. In the present study, we investigated whether(More)
Bacillus acidopullulyticus pullulanase (BaPul13A) is a widely used debranching enzyme in the starch industry. A few details have been reported on the heterologous expression of BaPul13A in Escherichia coli (E. coli). This study compares different E. coli expression systems to improve the soluble expression level of BaPul13A. When pET22b(+)/pET28a(+) was(More)
We report here the draft genome sequence of Paenibacillus polymyxa KF-1, which exhibits excellent antimicrobial activity. It encodes the synthase of bacitracin, kalimantacin, bacillomycin, iturin, fusaricidin, tridecaptin, and pelgipeptin and biosynthetic pathways of antiviral curldan and levan polysaccharides. Also, a novel prophage is involved in this(More)
BACKGROUND Cervical vertigo has been a controversial diagnosis for several years, and the lack of a diagnostic test is a critical problem. Musculoskeletal ultrasound (MSUS) is a real-time dynamic approach that is used to investigate the musculoskeletal and vascular systems. MATERIAL/METHODS In this study, MSUS was used to examine whether there is a(More)
—In order to reduce energy-consumption and hardware investment in wireless sensor networks, an improved DV-Hop localization algorithm based on energy-saving non-ranging optimization is proposed. In this algorithm, only one anchor node broadcasts its position coordinate information to other node, thus greatly reducing the energy consumption of the node.(More)
