OVERVIEW: There is an increased demand for the production of nextgeneration super-high-speed and low-power-consumption CMOS (complementary metal-oxide semiconductor) devices using SOI (silicon on insulator). Major global device manufacturers are actively commercializing this product. In SOI technology, a device is fabricated in a silicon layer (SOI layer) formed on a BOX (buried oxide) film. Al...

Methods We performed intraoperative MRI in 161 patients using a 0.2 Tesla Magnetom Open (Siemes AG, Erlangen, Germany), which is located in the radiofrequency shielded part of our ‘twin’ operating theatre. In brain tumor surgery (n=54) (46 cases of glioma located around eloquent areas and 8 cases of tumors in the lateral or third ventricle e.g. neurocytoma or subependymoma) and in surgery for t...

We investigated the catalytic activity and inhibition of the delta-class carbonic anhydrase (CA, EC 4.2.1.1) from the marine diatom Thalassiosira weissflogii, TweCA. The enzyme, obtained by cloning the synthetic gene, was an efficient catalyst for the CO2 hydration, its physiological reaction, with a kcat of 1.3x105s-1 and a kcat/KM of 3.3x107M-1s-1. A range of inorganic anions and small molecu...

In this study we investigated the anti-inflammatory effects of chronic ethanol (EtOH) treatment on lipopolysaccharide (LPS)-stimulated C6 glioma cells. The cells were chronically treated with 200mM EtOH; coincubation with LPS and EtOH was obtained upon addition of 2μg/ml LPS to the incubation medium in the last 24h of EtOH exposure. We found that EtOH prevented the LPS-induced production of tum...

A 58-year-old man presented with a fully circumferential, granular-type, laterally spreading tumor in the rectosigmoid (●" Fig.1a, ●" Fig.1b), which was diagnosed as an intramucosal cancer using magnifying endoscopy. En bloc resection was accomplished by endoscopic submucosal dissection (ESD) using the pocketcreation method [1]. Three submucosal pockets were created, leaving submucosal tissue b...

Excised shoot tips of sweet potato (Ipomoea babatas L.) were incubated in H2O2 or NaCl aqueous solution for 24h or 48h prior to a 3-day chilling at 2.5°C. Severity of chilling injury was visually observed during a post-chilling 7-day recovery at 21°C, and scored at 0 to 5 (none to most severe injury). In the first experiment, when cv. Purple (PUR) sweet potato shoots were subjected to 3-day chi...

Studies are presented on the influence of polyamines on prostatic chromatin- and non-histone-protein-associated protein kinase reactions involving both exogenous and endogenous substrates. The activities toward the model acidic protein substrate, dephosphophosvitin, were maximal at 160--200mM-NaCl (or -KCl or -NH4Cl). Under these conditions, spermidine and spermine added in concentrations up to...

We have initiated the characterization of the DNA helicases from HeLa cells, and we have observed at least 4 molecular species as judged by their different fractionation properties. One of these only, DNA helicase I, has been purified to homogeneity and characterized. Helicase activity was measured by assaying the unwinding of a radioactively labelled oligodeoxynucleotide (17 mer) annealed to M...

The number of cores which fit on a single chip is growing at an exponential rate while off-chip main memory bandwidth is growing at a linear rate at best. This core count to off-chip bandwidth disparity causes per-core memory bandwidth to decrease as process technology advances. Continuing percore off-chip bandwidth reduction will cause multicore and manycore chip architects to rethink the opti...

Corn stover harvest and transport cost functions were estimated for two harvest operations for a proposed biomass-to-ethanol conversion facility located in southern Minnesota, USA. This work presents an alternative methodology to estimating corn stover quantities and harvest costs at the county level, taking into account county-specific yields, transportation distances, erosion constraints, mac...
