Fasciola spp. found in Asian countries are diversified in nature, and they should therefore be characterized by spermatogenesis, ploidy and genetic differentiation as well as morphology. The present study showed that spermic diploid and aspermic triploid forms of Fasciola occurred in Vietnam. The spermic diploid specimens were accurately identified as F. gigantica, while the aspermic triploids could not be identified on the basis of their morphology by the ratio of body length and width and DNA ...

High quality ZnO films have been obtained by utilizing buffer layers fabricated via nitrogen mediated crystallization (NMC), where sputtering method is employed for preparation of both buffer layers and ZnO films. The crystal grain size of ZnO:Al (AZO) films with NMC-buffer layers is about 3 times larger than that of conventional films, which is considered to be due to the low nuclei density of NMC-buffer layers. As a result, the resistivity of AZO films drastically reduces from 4.76 m Ωcm for the ...

The characterization of energy influxes from plasma to substrate during sputter deposition of ZnO films is presented and discussed. Measurements were carried out in a triple rf magnetron sputter deposition system using calorimetric probes in various Ar/N2 and Ar/H2 mixtures at typical substrate positions. By variation of the probe bias the different contributions originating from the kinetic energy of charge carriers, the recombination of charge carriers (electrons and ions) at the surface as well ...

New drugs for multiple myeloma (MM) have dramatically improved patients' overall survival (OS). Autologous stem cell transplantation (ASCT) remains the mainstay for transplant-eligible MM patients. To investigate whether the post-ASCT prognosis of MM patients has been improved by new drugs, we undertook a retrospective observational analysis using the Transplant Registry Unified Management Program database in Japan. We analyzed 7323 patients (4135 men and 3188 women; median age, 59 years; range 16-77 ...

Anoikis, apoptosis because of loss of cell anchorage, is crucial for tissue homeostasis. Fibronectin not only provides a scaffold for cell anchorage but also harbors a cryptic antiadhesive site capable of inducing β1-integrin inactivation. In this study, this cryptic antiadhesive site is implicated in spontaneous induction of anoikis. Nontransformed fibroblasts (NIH3T3) adhering to a fibronectin substratum underwent anoikis during serum starvation culture. This anoikis was caused by proteolytic exposure ...

The acquisition of drug resistance mediated by the interaction of tumor cells with the extracellular matrix (ECM), commonly referred to as cell adhesion-mediated drug resistance (CAM-DR), has been observed not only in hematopoietic tumor cells but also in solid tumor cells. We have previously demonstrated that a 22-mer peptide derived from fibronectin, FNIII14, can inhibit cell adhesion through the inactivation of β1 integrin; when coadministered with cytarabine, FNIII14 completely eradicates acute ...

Unified synthesis of FD-891 analogs and their structure-activity relationship are described. By using stereoselective allylation/crotylation and Evans aldol chemistry, six side-chain fragments having different length and terminus were synthesized. These fragments were coupled with a macrolactone fragment, improved synthesis of which was also developed here, to generate FD-891 and five truncated analogs. These synthetic compounds as well as three analogs obtained from fermentation of gene-disrupted ...

Abstract The Glasgow Prognostic Score (GPS) has been established as a useful resource to evaluate inflammation and malnutrition and predict prognosis in several cancers. However, its prognostic significance in patients with heart failure (HF) is not well established. To investigate the association between the GPS and mortality in patients with HF, we assessed 870 patients who were 20 years old and more and had been admitted for acute decompensated HF. The GPS ranged from 0 to 2 points as previously ...

A variety of optically active carboxylic esters are produced by the kinetic resolution of racemic α-substituted carboxylic acids using achiral alcohols, aromatic or aliphatic carboxylic anhydrides, and chiral acyl-transfer catalysts. The combination of 4-methoxybenzoic anhydride (PMBA) or pivalic anhydride with the modified benzotetramisole-type catalyst ((S)-β-Np-BTM) is the most effective for promotion of the enantioselective coupling reaction between racemic carboxylic acids and a novel nucleophile, ...

ATP-binding cassette transporter A1 (ABCA1) is predicted to be involved in the control of apolipoprotein AI-mediated cholesterol efflux: biosynthesis of high-density lipoprotein (HDL). However, the effects of HMG-CoA reductase inhibitors (statins) on ABCA1 in the liver and the precise mechanisms of their actions have been obscure. The aims of this study were to determine whether statins (atorvastatin (Ato) and pitavastatin (Pit)) affect hepatic ABCA1 expression and to clarify the mechanisms of their actions ...

An 86-year-old woman had a pacemaker implanted into a subfascial pocket. After four months, the generator became exposed, and the pacemaker was removed. She exhibited a lack of prepectoral tissue. We therefore performed reimplantation in collaboration with plastic surgeons. We placed the leads via the extrathoracic subclavian venous approach, and plastic surgeons created a subpectoral pocket from the low lateral side of the pectoralis major muscle. General cardiologists rarely create subpectoral ...

A narrow-beam has been realized in a 1.3 μm Fabry-Perot laser diode monolithically integrated with a tapered waveguide lens. The beam divergences in the perpendicular and horizontal directions are reduced down to 12/spl deg/ and 11/spl deg/ by a selective area epitaxial growth technique. The threshold current has been kept as low as 14 mA comparable to the conventional ones. Neither kinks in the L-I curves nor changes of far-field patterns are observed in the wide temperature range from -40 to 80/ ...

Fasciolosis is an economically important disease of livestock caused by Fasciola hepatica, Fasciola gigantica, and aspermic Fasciola flukes. The aspermic Fasciola flukes have been discriminated morphologically from the two other species by the absence of sperm in their seminal vesicles. To date, the molecular discrimination of F. hepatica and F. gigantica has relied on the nucleotide sequences of the internal transcribed spacer 1 (ITS1) region.
