Electron energy-loss spectra of VO 2 have been measured from perfect single crystalline areas of 100–180 nm diameter in the metallic and insulating phases. A sharp peak has been observed at 1.2 eV in the valence electron excitation spectra of the metallic phase but not in those of the insulating phase. We assign the peak to an interband transition or d - d transition by inspecting the dielectric function derived from the present loss function with the help of an energy band diagram already given, ...

Electron energy-loss spectra of V 2 O 3 of the paramagnetic metallic (PM) and antiferromagnetic insulating (AFI) phases have been measured by a high-resolution transmission electron energy-loss spectroscopy (EELS) technique. An excitation at about 1 eV was previously observed in both the PM and AFI phases by an optical measurement and assigned to the excitation of a free-carrier plasmon. A sharp peak has, however, been observed at 1.1 eV in our EELS spectra of the PM phase but not in those of the AFI ...

Electron energy-loss spectra of (V 1- x Cr x ) 2 O 3 ( x =0.012) at the antiferromagnetic insulating (AFI), paramagnetic metallic (PM) and paramagnetic insulating (PI) phases have been measured using a high-resolution transmission electron energy-loss spectroscopy (EELS) microscope. The changes in the EELS spectra at the transition from the PM phase to the AFI phase are interpreted in a similar manner to the case of V 2 O 3 [Jpn. J. Appl. Phys. 37 (1998) 584]. The change in the electronic structure at the transition ...

Objective: Despite multiple and repeated exposures to HIV-1, some individuals possess no detectable HIV genome and show T-cell memory responses to the viral antigens. HIV-1-reactive mucosal IgA detected in such uninfected individuals suggests their possible immune resistance against HIV. We tested if the above HIV-1-exposed but uninfected status was associated with genetic markers other than a homozygous deletion of the CCR5 gene. Methods: Based on our mapping in chromosome 15 of a gene controlling ...

Lifestyle-related chronic illnesses, such as metabolic syndrome, type 2 diabetes, cancer, and dementia are rising at an alarming, epidemic rate. In this modern world of increasing lifespan, we are actually decreasing our health span, placing an undue burden on healthcare costs to society. Modern medicine has largely gotten away from addressing key issues to prevent or even reverse some of these chronic conditions. Yet the evidence for successful interventions in four key areas – nutrition, sleep, ...

Abstract We evaluated the effect of YM175 on bone in ovariectomized beagles fed a calcium-restricted diet for 18 months. Groups 1 (n = 6) and 2 (n = 6) underwent sham operation, and groups 3–6 were ovariectomized at the age of 21 months. Group 1 was fed standard dog chow (calcium: 1.4%), and groups 2–6 were given a low calcium diet (0.14%). Groups 3 (n = 7), 4 (n = 7), 5 (n = 7), and 6 (n = 7) were given YM175 orally at doses of 0, 0.01, 0.1, and 1.0 mg/kg/day, respectively. At the end of the experimental period, bone ...

To promote the functional restoration of the nervous system following injury, it is necessary to provide optimal extracellular signals that can induce neuronal regenerative activities, particularly neurite formation. This study aimed to examine the regulation of neuritogenesis by temperature-controlled repeated thermal stimulation (TRTS) in rat PC12 pheochromocytoma cells, which can be induced by neurotrophic factors to differentiate into neuron-like cells with elongated neurites. A heating plate ...

In the N-terminal region of the α-helix of the c-type lysozymes, two Asx residues exist at the 18th and 27th positions. Hen lysozyme has Asp18/Asn27 (18D/27N), and we prepared three mutant lysozymes, Asn18/Asn27 (18N/27N), Asn18/Asp27 (18N/27D), and Asp18/Asp27 (18D/27D). The stability of the wild-type (18D/27N) lysozyme supported the existence of a hydrogen bond between the side chain of Asp18 and the amide group at the N1 position in the α-helix, while the stability of the 18N/27D lysozyme supported ...

Benzalacetone synthase (BAS) is a plant-specific chalcone synthase (CHS) superfamily type III polyketide synthase (PKS) that catalyzes a one-step decarboxylative condensation of 4-coumaroyl-CoA with malonyl-CoA. The diketide forming activity of Rheum palmatum BAS is attributed to the characteristic substitution of the conserved active-site Phe215 with Leu (numbering in Medicago sativa CHS). To further understand the structure and function of R. palmatum BAS, four site-directed mutants (C197T, C197G, ...

A cDNA encoding a novel plant type III polyketide synthase was cloned and sequenced from the Chinese club moss Huperzia serrata (Huperziaceae). The deduced amino acid sequence of Hu. serrata polyketide synthase 1 showed 44–66% identity to those of other chalcone synthase superfamily enzymes of plant origin. Further, phylogenetic tree analysis revealed that Hu. serrata polyketide synthase 1 groups with other nonchalcone‐producing type III polyketide synthases. Indeed, a recombinant enzyme expressed ...

In Bordetella bronchiseptica, the functional type III secretion system (TTSS) is required for the induction of necrotic cell death in infected mammalian cells. To identify the factor(s) involved in necrotic cell death, type III-secreted proteins from B. bronchiseptica were analyzed using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and electrospray ionization tandem mass spectrometry. We identified a 69-kDa secreted protein designated BopC. The gene encoding BopC is ...

β-Carboline alkaloids are naturally occurring plant substances that have a wide spectrum of neuropharmacological, psychopharmacological, and antitumor effects. Recently, we have demonstrated that harmol, a β-carboline alkaloid, induces apoptosis by caspase-8 activation independently from Fas/Fas ligand interaction in human non-small cell lung cancer (NSCLC) H596 cells. Here, we found that harmol induces autophagy and cell death in human NSCLC A549 cells. Although harmol induced cell death in A549 ...

We describe the novel and facile preparation of Pt100− xCox alloy single-crystals and preliminary results on the electrochemical behavior of Pt100− xCox(111) surfaces in 0.1 M HClO4 solution as a function of Co composition. The prepared Pt-Co(111) surfaces were characterized by low energy electron diffraction and scanning tunneling microscopy; the results suggest the thermal formation of a Pt skin layer on the alloy surface. The cyclic voltammograms of the Pt100− xCox(111) electrodes exhibited increasingly ...

The presence of multiple types of β-galactosidases in a commercial enzyme preparation from Bacillus circulans ATCC 31382 and differences in their transgalactosylation activity were investigated. Four β-galactosidases, β-Gal-A, β-Gal-B, β-Gal-C, and β-Gal-D, which were immunologically homologous, were isolated and characterized. The N-terminal amino acid sequences of all of the enzymes were identical and biochemical characteristics were similar, except for galactooligosaccharide production. β-Gal- ...

Abstract Seed dormancy is an adaptive mechanism and an important agronomic trait. Temperature during seed development strongly affects seed dormancy in wheat (Triticum aestivum) with lower temperatures producing higher levels of seed dormancy. To identify genes important for seed dormancy, we used a wheat microarray to analyze gene expression in embryos from mature seeds grown at lower and higher temperatures. We found that a wheat homolog of MOTHER OF FT AND TFL1 (MFT) was upregulated after physiological ...

The arsenic distribution in the arsenic hyper-accumulating fern (Pteris vittata L.) was investigated using a synchrotron X-ray fluorescence microprobe. Fronds of various ages were subjected to XRF imaging analysis, and it was found that the arsenic distribution in the pinnae of fronds changed according to their stage of growth. The focused microbeam (3.5 × 5.5 μm2) produced by Kirkpatrick–Baez optics was applied to the fern in order to determine the elemental distribution in plant tissue and cell levels. ...

This study examined how boiling and drying treatments influenced various physical properties of the tension wood with gelatinous fibers (G-fibers) of a 29-yearold Zelkova branch. By boiling treatment, tension wood with numerous G-fibers contracted considerably in the longitudinal direction and the longitudinal Young’s modulus decreased in spite of the water-saturated condition. The drying treatment caused green tension wood and boiled tension wood with numerous G-fibers to shrink longitudinally and ...
