Polarization-Type Potential-Induced Degradation in Front-Emitter p-Type and n-Type Crystalline Silicon Solar Cells.

For SiO layers underneath the SiN antireflection/passivation layers of front-emitter p-type c-Si solar cells, this paper presents an investigation into their effects on polarization-type potential-induced degradation (PID), in addition to a comparison of polarization-type PID behavior in front-emitter p-type c-Si cells and front-emitter n-type c-Si cells. After PID tests with a bias of +1000 V, p-type c-Si cells without SiO layers underneath the SiN layers showed no degradation, although p-type c-Si cells with approx. 10 nm thick SiO layers showed polarization-type PID, which is characterized by a reduction of the short-circuit current density and the open-circuit voltage.

Bis-pyrene-labeled molecular beacon: a monomer-excimer switching probe for the detection of DNA base alteration.

A new bis-pyrene-labeled oligonucleotide probe (BP-probe) has been designed for the detection of a single base mismatch in single strand (ss) DNA as a target. The sequence of BP-probe was chosen to form stem-loop structure similar to a molecular beacon (MB-probe), yielding bis-pyrene-labeled molecular beacon (BP-MB-probe). Partially double stranded (ds) BP-MB-probes were prepared by complexation with oligonucleotides whose sequences are complementary to the loop segment but not to the stem and exchangeable with the target DNA.

Purpose: We studied the relation between intratumoral hemodynamics and histopathologic characteristics in patients with colorectal carcinoma.

Methods: A series of 82 patients with 28 well-differentiated adenocarcinomas, 40 moderately differentiated adenocarcinomas, 10 poorly differentiated adenocarcinomas, and 4 mucinous adenocarcinomas underwent color Doppler examination and surgical treatment. The waveform of blood flow in the thickened wall of the colon was analyzed by determining the maximum velocity (Vmax) and resistance index (RI).

Effect of controlled zinc release on bone mineral density from injectable Zn-containing beta-tricalcium phosphate suspension in zinc-deficient diseased rats.

The purpose of this study was to evaluate the efficacy of zinc (Zn)-containing beta-tricalcium phosphate (Zn-TCP) in correcting the bone mineral deficiency noted in osteoporosis using ovariectomized rat model. Four rats were used for each of the four experimental groups: D0, D10, D20, and N10. The rats in D0, D10, and D20 groups were ovariectomized, and fed a vitamin D-, Ca-, and Zn-deficient diet, and induced Zn-deficient osteoporoses for 9 weeks.

Sympathetic nervous system mediates cold stress-induced suppression of natural killer cytotoxicity in rats.

The aim of the present study is to investigate the mechanisms of suppression of splenic natural killer (NK) cytotoxicity caused by cold stress, using 6-hydroxydopamine (6-OHDA) as chemical sympathectomy. The NK activity was measured by (51)chromium release assay. Central sympathectomy with intracerebroventricular injection of 6-OHDA significantly reduced the elevation of the plasma corticosterone level, the expression of Fos in hypothalamic paraventricular nucleus and in locus coeruleus, as well as the suppression of NK activity induced by cold stress at 4 degrees C for 4 h.

Fluoroquinolones represent a major class of antibacterial agents with great therapeutic potential. In this study, we designed m-aminophenyl groups as novel N-1 substituents of naphthyridones and quinolones. Among newly synthesized compounds, 7-(3-aminoazetidin-1-yl)-1-(5-amino-2,4-difluorophenyl)-8-chloro-6-fluoro-4-oxo-1,4-dihydroquinoline-3-carboxylic acid (4) has extremely potent antibacterial activities against Gram (+) as well as Gram (-) bacteria.

Morphologic and hemodynamic changes after stent placement for experimental carotid aneurysm.

Stent assisted coil embolization is useful in treating broad neck aneurysms, and there are many kinds of stents that can be applied in the cerebral artery, however their characteristics are not well known. We investigated and compared morphologic and hemodynamic changes before and after stent placement when several different kinds of stents were applied to experimental aneurysms. Experimental aneurysms in eight pig carotid arteries were used.

Sequential acquisition of norfloxacin and ofloxacin resistance by methicillin-resistant and -susceptible Staphylococcus aureus.

The acquisition of ofloxacin resistance by a susceptible clinical Staphylococcus aureus strain was found to be achieved in two sequential steps: the first step was accompanied by 4-fold increases in the ofloxacin MIC and 8- to 16-fold increases in the norfloxacin MIC. The second step was accompanied by further increases in both the ofloxacin and the norfloxacin MICs. A mutation of the gyrA gene resulting in an amino acid substitution was found in the second-step but not in the first-step resistant subclone.
