Nanocomposites α-Fe/Fe3B/Y2O3 were prepared by a melt-spun technique, and the electromagnetic wave absorption properties measured in 0.05–20.05 GHz range. Compared with α-Fe/Y2O3 composites, resonance frequency (fr) of shifted to higher range due large anisotropy field (HA) tetragonal Fe3B (∼0.4 MA/m). The relative permittivity (εr=εr′−jεr″) was constantly low over 0.5–10 region, which indicates that composite powders have high resistivity (ρ=∼100 Ω m). effective (reflection loss <−20...
Abstract The CRISPR/Cas system, in which the Cas9 endonuclease and a guide RNA complementary to target are sufficient for RNA-guided cleavage of DNA, is powerful new approach recently developed targeted gene disruption various animal models. However, there little verification microinjection methods generating knockout mice using this approach. Here, we report system. We compared three injection: (1) injection DNA into pronucleus, (2) pronucleus (3) cytoplasm. found that cytoplasm was most...
Monodispersed hollow magnetite spheres with diameter of about 500 nm and a shell thickness approximately 150 were synthesized through simple solvothermal process in ethylene glycol (EG) the presence polyvinyl-pyrrolidone urea for electromagnetic absorption applications. The electron microscopy images showed that obtained are composed small particles size 50–100 nature. A possible formation mechanism was proposed it confirmed by control experiments. exhibited high saturation magnetization...
Fe nanowires with 70–200nm in diameter and 20–50μm length were synthesized by a chemical vapor deposition method for electromagnetic wave absorption application. The frequency dependences of relative permittivity (εr) permeability (μr) strongly dependent on the wires. Compared micrometer wires or flakelike samples, exhibited magnetic resonance (μr″) peak range 1–18GHz, suggesting that have significant effect reducing eddy current loss, therefore, resin compacts 29vol% thicknesses 1.3–4.0mm...
Human CYP2A6, which is predominantly expressed in liver, a key enzyme responsible for the metabolism of nicotine, coumarin, and some pharmaceutical drugs. CYP2A6 also sex steroid-responsive tissues such as breast, ovary, uterus, testis, adrenal grand. In this study, we examined regulation <i>CYP2A6</i> gene by estrogen. Reverse transcription-polymerase chain reaction (RT-PCR) assays revealed that mRNA was induced estradiol estrogen receptor (ER)-positive MCF-7 (2.9-fold) HepG2 (1.3-fold)...
Recently, mathematical analysis clarified that sp;{2} hybridized carbon should have a three-dimensional crystal structure (K4) which can be regarded as twin of the sp;{3} diamond crystal. In this study, various physical properties K4 crystal, especially for electronic properties, were evaluated by first principles calculations. Although is in metastable state, possible pressure induced structural phase transition from graphite to was suggested. Twisted pi states across Fermi level result metallic new
We report a template-free approach to prepare hollow porous cobalt spheres by combining facile solvent-thermal route with chemical reduction process. The synthesized microspheres diameter of approximately 2–4 μm have shell thickness about 150 nm. Co microsphere is built from particle-like ligaments ca. 80–150 nm and there are lot pores size several tens on the shell. exhibited saturation magnetization (Ms) 163.0 emu g−1 large coercivity (Hcj) 307.9 Oe. epoxy resin composites 30 wt% 60 sample...
This article evaluates the suitability of cadavers embalmed by saturated salt solution (SSS) method for surgical skills training (SST). SST courses using have been performed to advance a surgeon's techniques without any risk patients. One important factor improving is specimens, which depends on embalming method. In addition, infectious and cost involved in are problems that need be solved. Six were 3 methods: formalin solution, Thiel (TS), SSS methods. Bacterial fungal culture tests...
[Purpose] This study investigated the effect of forward head posture on upper and lower thoracic shape in adults to better understand relationship between a respiratory function. [Participants Methods] Fifteen healthy males were recruited after obtaining informed consent from all participants. All participants instructed respire both neutral postures while seated. Respiratory function was assessed using spirometry. Thoracic during respiration 23 markers thorax compared 2 postures. [Results]...
Abstract Since the early 1990s, Adschiri and his colleagues have performed research on use of supercritical water in diverse applications, including heavy oil reforming, waste polymer decomposition chemical raw materials recovery, cellulose hydrolysis sugar lignin nanoparticle synthesis. Regarding inorganic synthesis, they invented hydrothermal synthesis for continuous flow metal oxide nanoparticles, which has already found worldwide industrial applications. They proposed a two-fluid mixing...
The saturation magnetization values (Ms) of α-Fe∕Ba3Co1.8Fe23.6Cr0.6O41 nanocomposites prepared by mechanically alloying α-Fe with Ba3Co1.8Fe23.6Cr0.6O41 powders increased increasing the concentration α-Fe. showed higher coercivity than and because effects shape anisotropy exchange bias. resin compacts 33.5 vol % (38, 70, 85 α-Fe) provided good electromagnetic wave absorption performances in ranges 7.5–16.0, 5.4–10.5, 4.3–8.3 GHz over absorber thicknesses 1.3–2.5, 1.6–3.0, 1.7–3.2 mm, respectively.
Polysulfides formed through the breakdown of elemental sulfur or other compounds were found to be reduced H 2 S by hyperthermophilic archaebacterium Pyrococcus furiosus during growth. Metabolism polysulfides organism was dissimilatory, as no incorporation 35 S-labeled detected. However, [ S]cysteine and S]methionine incorporated into cellular protein. Contact between is not necessary for metabolism. The sulfide generated from metabolic reduction dissociates a strong nucleophile, HS − , which...
AbstractVitamin K2 (menaquinone-4: VK2) is a potent inducer for apoptosis in leukemia cells vitro. HL-60bcl-2 cells, which are derived from stable transfectant clone of the human bcl-2 gene into HL-60 cell line, show 5-fold greater expression Bcl-2 protein compared with HL-60neo control transfected vector alone. VK2 induces whereas resistant to induction by but inhibition growth along an increase cytoplasmic vacuoles during exposure VK2. Electron microscopy revealed formation autophagosomes...

Entrapment of the superior cluneal nerve (SCN) in an osteofibrous tunnel space surrounded by iliac crest and thoracolumbar fascia is a cause low-back pain (LBP). Several anatomical surgical reports describe SCN entrapment as LBP, recent clinical study reported that patients with suspected disorder constitute approximately 10% suffering from LBP and/or leg symptoms. However, detailed rare. The purpose this was to investigate courses branches ascertain frequency entrapment.Branches were...
