Comparative genomics of nucleosome positions provides a powerful means for understanding how the organization of chromatin and the transcription machinery co-evolve. Here we produce a high-resolution reference map of H2A.Z and bulk nucleosome locations across the genome of the fly Drosophila melanogaster and compare it to that from the yeast Saccharomyces(More)
Recent analyses of RNA polymerase II (Pol II) revealed that Pol II is concentrated at the promoters of many active and inactive genes. NELF causes Pol II to pause in the promoter-proximal region of the hsp70 gene in Drosophila melanogaster. In this study, genome-wide location analysis (chromatin immunoprecipitation-microarray chip [ChIP-chip] analysis)(More)
A low-noise amplifier is the first active stage of a CMOS RF receiver. The inductively degenerated common-source LNA (CS-LNA) topology is currently popular because it achieves high gain, low noise figure, etc. The amplifier's performance is reviewed and the optimum Q value that gives the minimum noise figure is derived. It is then compared to the(More)
The resource efficiency and dependability of a trust system are the most fundamental requirements for any wireless sensor network (WSN). However, existing trust systems developed for WSNs are incapable of satisfying these requirements because of their high overhead and low dependability. In this work, we proposed a lightweight and dependable trust system(More)
Germline stem cell lines possess the abilities of self-renewal and differentiation, and have been established from both mouse and human ovaries. Here, we established a new female germline stem cell (FGSC) line from post-natal rats by immunomagnetic sorting for Fragilis, which showed a normal karyotype, high telomerase activity, and a consistent gene(More)
A fully-integrated common-gate UWB LNA employs a stagger-compensated series peaking technique to extend bandwidth, and a capacitor cross-coupled g<sub>m</sub>-boosting technique to reduce NF and power. A simple input matching scheme obviates the use of multiple inductors and complex filters. For two versions in 0.18 mum CMOS, BW extension factors are(More)
BACKGROUND Managing lesions situated in the atrium of the lateral ventricle remains a challenging neurosurgical problem. The purposes of this study were to examine the microsurgical anatomy of the atrium of the lateral ventricle and the optic radiation and to define the differences in the exposure obtained by various surgical approaches. METHODS Fifteen(More)
Increased oxidative stress and circulating free fatty acids (FFA) has been suggested to involve in the pathogenesis of diabetic nephropathy. TRIB3 can inhibit FFA and reactive oxygen species (ROS) stimulated podocyte production of MCP-1. Smoking increases the production of reactive oxygen species, which accelerates oxidative stress under hyperglycemia. To(More)
OBJECTIVE Elevation of the lateral orbital rim and zygomatic arch during an orbitozygomatic craniotomy requires a bone cut across the zygoma, which commonly extends into the lateral edge of the inferior orbital fissure. The zygomaticofacial foramen has been identified as a superficial landmark for the cut that extends into the inferior orbital fissure. This(More)
