There are no prior reports of totally endoscopic minimally invasive cardiac surgery for combined ventricular septal defect closure and aortic valve replacement. We utilized a periareolar incision as the main access, inserting cardioplegia line, vent tube cross-clamp entirely through this incision. Only three ports (main incision, camera port left-hand port) were used. A three-dimensional endoscope facilitated precise techniques. The type I was approached closed from side using Gore-Tex...
A translation experiment of field-reversed configuration (FRC) plasma is performed on the FIX machine [Shiokawa and Goto, Phys. Fluids B 5, 534 (1993)]. The translated FRC bounces between magnetic mirror fields at both ends a confinement region. loses some its axial kinetic energy when it reflected by field, eventually settles down in In this reflection process, temperature rises significantly. Such rethermalization has been observed OCT-L1 experiments [Ito et al., 30, 168 (1987)], but...
Two digital image processing methods, capable of composing microscope images with increased depth focus and mapping 3-D distribution on the altitude or thick object, are presented: one uses pseudocolor display focal-series images, other considers local variance each images. Experimental results demonstrate usefulness both methods. The high-speed system developed by authors plays an important role in
Tempeh is a traditional Indonesian soybean-fermented food produced by filamentous fungi, Rhizopus sp. and Fusarium We isolated sequenced the genomic gene cDNA clone encoding novel protease (FP) from BLB.

An encoded protein of 250 amino acids. predicted acid sequence FP showed highest homology, 76%, with that trypsin oxysporum. hydrolysis activity toward synthetic peptide higher than any other tested, including Nattokinases. Furthermore,...
We have proposed an experimental methodology which makes it possible to deposit silicon carbide (SiC) films on Si substrates with a low-energy mass-selected ion beam system using hexamethyldisilane (HMD) as gas source. In this study, one of the fragment ions produced from HMD, SiCH4+, was mass-selected. The energy approximately 100 eV. Then, SiCH4+ were irradiated Si(100) substrate. When temperature substrate set at 800 °C during irradiation, X-ray diffraction and Raman spectroscopy...

It found the spreads narrow no energetic produced, suggesting unlikely to cause any significant damage deposited films actual Cat-CVD...
Proteasome assembling chaperone (PAC) 3 acts as a homodimer and plays an important role in proteasome formation. We screened JBIR-22 (1) inhibitor for protein−protein interaction (PPI) of PAC3 from our natural product library using protein fragment complementation assay (PCA) with monomeric Kusabira-Green fluorescent (mKG) vitro found that 1 exhibited potent inhibitory activity against homodimerization. Compound showed long-term cytotoxicity the human cervical carcinoma cell line, HeLa. This...

Surface modification of poly(methyl methacrylate) (PMMA) films by hydrogen-plasma exposure has been studied in the light sputtering resistance polymer-based materials plasma etching processes. measurements PMMA were performed with X-ray photoelectron spectroscopy, Fourier transform infrared Raman and spectroscopic ellipsometry. It found that oxygen atoms are preferentially removed from surface when a film is subjected to exposure, depth being about 40 nm case we examined. Hydrogen-plasma...
A novel, Gram-stain-positive bacterial strain, Mer 29717(T), was isolated from the branchia (gills) of a Japanese codling, Physiculus japonicus, collected bottom waters Suruga Bay in Shizuoka, Japan. Phylogenetic analysis based on 16S rRNA gene sequences indicated that this strain represents distinct lineage within family Dermacoccaceae and related most closely to members genera Demetria Yimella. It shared highest sequence similarity (95.1 %) with Yimella lutea YIM 45900(T). Strain 29717(T)...
We found that the atomic-concentration-ratio of carbon to silicon (C/Si ratio) in carbide (SiC) films formed by thermal chemical vapor deposition (CVD) was much greater than 1 when source gas for CVD dimethylsilane (DMS). Thus, we tried change carbon-inclusion levels film injecting some ion beams into a depositing SiC during process with DMS. Three beams, i.e., Si+, SiCH5+, or C+ ions were injected films.
