The band gap of semiconductors like silicon and silicon carbide (SiC) is the key for their device properties. In this research, the band gap of 6H-SiC and its temperature dependence were analyzed with silicon 2p x-ray absorption spectroscopy (XAS), x-ray emission spectroscopy (XES) and resonant inelastic x-ray scattering (RIXS) allowing for a separate analysis of the conduction-band minimum (CB...

Antioxidants partially ameliorated the negative effects of reactive oxygen species (ROS) produced during cryopreservation. The objective of the present study was to investigate the effect of cysteine and a water-soluble vitamin E analogue on the quality of frozen-thawed epididymal cat spermatozoa. Epididymal spermatozoa were collected from eight male cats and divided into three aliquots; these ...

INTRODUCTION Purpureocillium lilacinum is emerging as a causal agent of hyalohyphomycosis that is refractory to antifungal drugs; however, the pathogenic mechanisms underlying P. lilacinum infection are not understood. In this study, we investigated the interaction of P. lilacinum conidia with human macrophages and dendritic cells in vitro. METHODS Spores of a P. lilacinum clinical isolate we...

We investigate the extent to which price deviations from fundamental values in an experimental asset market are due to the uncertainty of subjects regarding others’ rationality. We do so by comparing the price forecasts submitted by subjects in two market environments: (a) all six traders are human subjects (6H), and (b) one human subject interacts with five profitmaximizing computer traders wh...

OBJECTIVE To study the actions of c-Myc gene fragments in restenosis after coronary artery bypass grafting (CABG). MATERIALS AND METHODS A total of 25 healthy pure breeds New Zealand white rabbits were randomly divided into 5 groups according to weight, 5 in each group. The external jugular vein is placed at ipsilateral common carotid artery and sampling at 6h, 2d, 7d, 14d and 28d. The expres...

The role of the treatment for latent tuberculosis infection (LTBI) has been underscored in the intermediate tuberculosis (TB) burden countries like South Korea. LTBI treatment is recommended only for patients at risk for progression to active TB-those with frequent exposure to active TB cases, and those with clinical risk factors (e.g., immunocompromised patients). Recently revised National Ins...

We report on experimental demonstration of high frequency torsional resonators based on microdisk structures enabled by a “smart-cut” 6H-silicon carbide (6H-SiC) technology. Circular microdisks axially supported by pairs of thin tethers, with diameters of 5–15 lm, exhibit torsional-mode micromechanical resonances with frequency of 1–60 MHz, and quality (Q) factors up to 1280 at room temperature...

Excessive stretch of the cervical facet capsular ligament induces persistent pain and spinal plasticity at later time points. Yet, it is not known when such spinal modifications are initiated following this painful injury. This study investigates the development of hyperalgesia and neuronal hyperexcitability in the spinal cord after a facet joint injury. Behavioral sensitivity was measured in a...
