Bile acid-binding agents are known to lower blood cholesterol levels and have been clinically used for the treatment of hypercholesterolemia. We previously showed that tannin-rich fiber from young persimmon (Diospyros kaki) fruits had bile acid-binding properties. In this study, we performed a randomized, double-blind, placebo-controlled trial to investigate the hypocholesterolemic effects of tannin-rich fiber in humans. The subjects (n = 40, plasma total cholesterol levels 180-259 mg/dl) were divided into 3 groups and ingested cookie bars containing 0 g (placebo group, n = 14), 3 g (low-dose group, n = 13), or 5 g (high-dose group, n = 13) of tannin-rich fiber 3 times daily before meals for 12 weeks. Plasma total cholesterol levels decreased significantly in the low-dose (12 weeks, p < 0.005) and high-dose (6 weeks, p < 0.05; 12 weeks, p < 0.001) groups. In addition, plasma low-density lipoprotein cholesterol levels decreased significantly in the high-dose group (6 weeks, p < 0.05; 12 weeks, p < 0.001). These improvements were not accompanied by changes in plasma high-density lipoprotein cholesterol or plasma triglyceride levels. Our findings indicate that tannin-rich fiber from young persimmon fruits is a useful food material for treating hypercholesterolemia. Copyright © 2012 S. Karger AG, Basel. Source

The punchless drawing with Maslennikov's technique was applied to the circular cup drawing of magnesium alloy AZ31B sheet under cold condition. The elastic rubber ring was used instead of the 'hard' punch, where the compressed ring dragged the sheet inward the die cavity. Attainable circumferential strain of the blank was increased by this technique with repetitive drawing operation. Thickness of the rubber pad affected little the attainable strain. The shape appearance became better when a harder rubber was used. The cup forming by single drawing operation was also tested using a small die shoulder radius. The LDR of 1.250 was obtained with the straight cup wall. Further, the computation of the punchless drawing was also conducted for the single drawing operation. The computed deformation pattern was well consistent with the corresponding experimental result. © 2010 American Institute of Physics. Source

A commercially available color scanner was used as an inexpensive input device for convenient, rapid and minute color measurements. Color image analysis was applied to the color measurements of 50 kinds of mono-colored fabrics. The y -correction was applied to transformation from sRGB to XYZ of CIE color system. CIE L*, a*, b*, C*and h were obtained for each pixel (i,j) in the image of mono-colored fabrics, using the CIELAB formula. Averaged values of X, Y, Z , L*, C*and h of all pixels , AVE-X, AVE-Y, AVE-Z, AVE-L*, AVE-C*and AVE-h, respectively were compared with those measured with a color difference meter. A very good linear correlation with the coefficient, 1.0 were obtained between the two measured quantities. The agreements show that color measurements with a scanner can replace the conventional color difference measurements. The former method is convenient, rapid and measurable of the minute color pattern with ca. 0.35mm resolution. The color measurements were also applied to multi-colored patterns of fabrics. Detergency of color patterned fabrics soiled with grape and orange fruit juices, can be evaluated from values of color information parameters such as AVE-L*, AVE-C*and AVE-h. ©2011 Jpn.Res.Assn.Text.End-Uses.

Soy isoflavonoids have many useful properties. However, they are metabolized in vivo, including in humans. The effect of the metabolism of soy isoflavonoids on their properties is not fully understood. We have isolated the bacterial strain SY8519, which has been shown to metabolize daidzein to O-desmethylangolensin and to produce 2-(4-hydroxyphenyl)propionic acid from genistein. According to chiral HPLC analysis, the 2-(4-hydroxyphenyl)propionic acid obtained from the bacterium was optically active. To determine the absolute stereochemistry of the microbial product, we prepared (S)-2-(4-hydroxyphenyl) propionic acid from (S)-2-phenylpropionic and concluded that the microbial product had an R-configuration by chiral HPLC analysis. We also applied the metabolite to mouse adipocytes and found that 2-HPPA was less effective at reducing leptin secretion than the parent compound genistein. Our results suggested that 'O-desmethylangolensin-production' attenuates the effect of soy isoflavonoids by reducing not only the activity of daidzein but also that of genistein. © 2012 Elsevier Ltd.

We have developed a new Si-based anode for lithium secondary batteries consisting of a carbon paper substrate and Si/C composite deposited on it (Si/C/CP electrode). The Si/C composite was formed by pyrolysis of a slurry consisting of Si power and THF solution of PVC as the carbon precursor. The electrode contains no additional conductive carbon and binder, which supports the tight contact among the Si particle, pyrolytic carbon and carbon paper. The Si/C/CP electrode with the three-dimensional carbon fiber framework of the carbon paper was also advantageous to absorb severe volume changes of silicon particles. The electrode performance revealed that the Si/C/CP electrode prepared from the mixture of Si and PVC with the ratio of 10:90 by weight had a quite high initial capacity of 1720 mAh g-1 and initial Coulombic efficiency of 90%, and also exhibited excellent capacity retention with a reversible capacity of 1200 mAh g-1 even after 100 cycles. © 2013 The Authors.
