This study investigated the effects of the consumption of 1% or 2% (v/v) ethanol in drinking water for 12 wk on rats fed a high-fat diet. Body weight gain, food intake, and fluid intake were unaffected by ethanol intake. Adipose tissue weight, and serum glucose and lipids were unaffected. Compared to the control (no ethanol), 1% ethanol intake significantly reduced serum levels of alanine aminotransferase (ALT), lactate dehydrogenase (LDH), and ammonia (p<0.05), whereas 2% ethanol intake did so to a lesser extent. Serum urate was significantly lower in both the 1% and 2% ethanol groups than that in the control group (p<0.05). The results suggest a low dose of ethanol has beneficial effects on liver function and serum urate in rats fed a high-fat diet. © 2014, Center for Academic Publications Japan. All Rights Reserved.

We dyed cotton fabric samples using colored clay pigments, which can be recovered from dyehouse effluent and be reused. The Lab color space (CIE L*a*b*) values of both the clay pigments and the fabric samples after dying were measured. The compounds in the pigments, and the compounds adhering to the dyed fabrics, were analyzed using XRF, XRD, SEM and EDS. We then determined which minerals affected the color of the clay pigments and the dyed fabrics and discussed their interrelationships in our analyses.

Cotton woven fabrics were treated with ultrasonic and ultraviolet irradiation to prepare a fabric modified by two types of titanium dioxide (TiO2). The specimens modified by TiO2 were investigated on the wash durability and aesthetic properties. The specimen fabrics prepared by irradiation of ultrasonic and ultraviolet (UV) light increased supporting TiO2 compared to that modified only by ultrasonic irradiation. The prepared cotton fabrics, i.e., TiO2 stably-maintained on the cotton fabric, had a resistance to washing. On the measure of aesthetic properties, untreated cotton fabrics changed their properties to the rougher surface, lager "SHARI" and smaller "FUKURAMI". However, cotton fabrics modified by TiO2 reduced deterioration of aesthetic properties by the effect of UV light. Cotton fabrics modified by anatase TiO2 - SiO2 complex show the less effects on damage of fabrics. In the case that anatase TiO2 fabrics were applied to the degradation system of Orange II dye, the degradation rate of Orange II was 100% under UV light irradiation for 24 hours. © 2011 Jpn.Res.Assn.Text.End-Uses.

Qualitative research focusing primarily on advanced-proficiency second language (L2) learners suggests that online corpora can function as useful reference tools for language learners, especially when addressing phraseological issues. However, the feasibility and effectiveness of online corpus consultation for learners at a basic level of L2 proficiency have been relatively unexplored. The current study of Japanese-L1 (first language) learners in an EFL (English as a foreign language) context (N=117) addresses these gaps in research. A preliminary investigation (Experiment 1) examined EFL learners (n=78) as they used the Corpus of Contemporary American English (COCA: Davies, 2008–) to revise essays. Experiment 2 (n=39) used a within-subjects comparison to determine whether participants attained greater accuracy in supplying the missing word in a gap-fill test when using an electronic dictionary or COCA. The survey results from the two experiments revealed that participants generally found using an online corpus difficult. In Experiment 2, a paired-samples t-test showed that participants, at an alpha of p=.05 two-tailed, were marginally better able to answer test questions when using the online corpus than they were when using an electronic dictionary, p=0.030. The implications of the study within the context of previous research are discussed along with pedagogical recommendations and possible avenues for future research.

The ceramide (Cer) content of skin and glucosylceramide (GlcCer) intake affect skin moisture conditions, but their mutual relation in skin remains unclear. For clarification of that mutual relation, carbon stable isotopes (12C and 13C) are useful as a tracer. However, carbon isotopic measurement has not been applied to the study of clarifying their skin moisturizing effects. Therefore, we used gas chromatography/combustion/isotope ratio mass spectrometry (GC-C-IRMS) to ascertain the appropriate conditions for carbon isotopic measurements using synthesized Cer (SCer) in substitution for very low concentrations of Cer in skin. SCer was derivatized to trimethylsilylated SCer (TMS-SCer) quantitatively using N-trimethylsilylimidazole (TMSI) depending on the amount of SCer. The derivatization rates were 75-85%. Excess TMSI was removed using three cycles of hexane-water distribution. Under these conditions, carbon isotopic measurements of TMS-SCer conducted using GC-C-IRMS showed high repeatability and good inter-day variation (S.D. < 0.3‰). The carbon stable isotope ratio value (δ13C) of SCer calculated using a mass balance equation was compared with δ13C of underivatized SCer, which was regarded as the actual δ13C of SCer obtained using sealed tube combustion method. The difference between the calculated δ13C of SCer and δ13C of the underivatized SCer depended on the TMSI reagent supplier and on the number of hydroxyl groups to be derivatized in SCer. For accurate δ13C of Cer in skin using GC-C-IRMS, the measured δ13C of a target TMS-Cer must be calculated using a correction factor representing the difference in δ13C of underivatized standard SCer from that of TMS-standard SCer having a structure resembling that of the target Cer in skin. In addition, we show that the same lot of TMSI reagent from a specific supplier must be used throughout the experiments. © 2014 by Japan Oil Chemists’ Society.
