This study examined the accumulation and tissue distribution of radioactive cesium nuclides in Japanese Black beef heifers raised on roughage contaminated with radioactive fallout due to the accident at the Fukushima Daiichi Nuclear Power Station on March 2011. Radiocesium feeding increased both 134Cs and 137Cs levels in all tissues tested. The kidney had the highest level and subcutaneous adipose had the lowest of radioactive cesium in the tissues. Different radioactive cesium levels were not found among parts of the muscles. These results indicate that radiocesium accumulated highly in the kidney and homogenously in the skeletal muscles in the heifers.

A water-soluble and low-molecular-weight fraction (SB) was obtained from tomato paste. The effects of SB on the formation of advanced glycation end-products (AGE) in protein glycation were studied by the methods of specific fluorescence, ELISA and a Western blot analysis, using the anti-AGE antibody after incubating protein with sugar. The results suggest that SB had strong inhibitory activity, in comparison with aminoguanidine as a positive control, and that the inhibitory mechanism of SB differed from that of aminoguanidine to involve trapping of reactive dicarbonyl intermediates in the early stage of glycation. SB contained an antioxidant, rutin, which showed potent inhibitory activity. The results also suggest that rutin chiefly contributed to inhibiting the formation of AGE, and that other compounds in SB may also have been related to the activity.

The effects of the administration of molecular hydrogen-saturated drinking water (hydrogen water) on hepatic gene expression were investigated in rats. Using DNA microarrays, 548 upregulated and 695 downregulated genes were detected in the liver after 4 weeks of administration of hydrogen water. Gene Ontology analysis revealed that genes for oxidoreduction-related proteins, including hydroxymethylglutaryl CoA reductase, were significantly enriched in the upregulated genes.

Acetic acid (AcOH), a main component of vinegar, recently was found to suppress body fat accumulation in animal studies. Hence we investigated the effects of vinegar intake on the reduction of body fat mass in obese Japanese in a double-blind trial. The subjects were randomly assigned to three groups of similar body weight, body mass index (BMI), and waist circumference. During the 12-week treatment period, the subjects in each group ingested 500 ml daily of a beverage containing either 15 ml of vinegar (750 mg AcOH), 30 ml of vinegar (1,500 mg AcOH), or 0 ml of vinegar (0 mg AcOH, placebo). Body weight, BMI, visceral fat area, waist circumference, and serum triglyceride levels were significantly lower in both vinegar intake groups than in the placebo group. In conclusion, daily intake of vinegar might be useful in the prevention of metabolic syndrome by reducing obesity.

Maillard reaction inhibitors could be useful therapeutics for diabetes and other age-related diseases. We isolated for the first time 4-O-demethylsilvaticol (1) and (−)-mitorubrin (2) as Maillard reaction inhibitors from Paecilomyces sp. 3193B. Among the isolated inhibitors, 2 showed most potent inhibitory effect by an SDS–PAGE assay on cross-linked protein formation and by a fluorescent assay on AGE formation.

We evaluated the cytotoxicity of surfactants in human cells. Synthetic surfactants showed different cytotoxicity levels depending on their structures. The cytotoxicity of commercial washing products was determined mainly by the contents of surfactants. All of them induced premature senescence in normal cells, but not in tumor-derived or immortalized cells, under sublethal conditions. Residual surfactants might be a risk factor for skin aging.

Elderberry (Sambucus nigra L.) has traditionally been used for treating influenza and colds. We evaluated the antiviral effect of concentrated juice of elderberry (CJ-E) on the human influenza A virus (IFV). CJ-E had a relatively strong effect on IFV-infected mice, although its anti-IFV activity was weak in a cell culture system. The in vivo anti-IFV activities of the fractions were determined after separating CJ-E by ultrafiltration and anion-exchange chromatography. Oral administration of the high-molecular-weight fractions of CJ-E to IFV-infected mice suppressed viral replication in the bronchoalveolar lavage fluids (BALFs), and increased the level of the IFV-specific neutralizing antibody in the serum, as well as the level of secretory IgA in BALFs and feces. Fr. II from high-molecular-weight fraction HM, which contained acidic polysaccharides, showed relatively strong defense against IFV infection. We conclude that CJ-E had a beneficial effect by the stimulating immune response and preventing viral infection.

Bisphenol A (BPA), a putative endocrine disruptor, may be taken up by humans via the diet and have adverse effects on human health. In this study, we evaluated whether the probiotics, Bifidobacterium breve strain Yakult (BbY) and Lactobacillus casei strain Shirota (LcS), could exert a protective effect against dietary exposure to BPA. A group of rats fed on a diet containing 5% BbY or 5% LcS showed three advantageous effects compared to the control group; (i) the area under the blood concentration-time curve of BPA after its oral administration was significantly decreased, (ii) the amount of BPA excreted in the feces was significantly greater (2.4 times), and (iii) the percentage of BPA bound to the sediment fraction of the feces was significantly higher. These results suggest that BbY and LcS reduced the intestinal absorption by facilitating the excretion of BPA, and that these probiotics may suppress the adverse effects of BPA on human health.

The edible purple laver, Porphyra yezoensis, contained 51.49±1.51 μg of vitamin B12 compounds per 100 g dry weight of the laver (mean±SEM, n=4). A vitamin B12 compound was purified from the lyophilized purple laver and partially characterized. The silica gel 60 TLC and reversed-phase HPLC patterns of the purified pink-colored compound were identical to those of authentic vitamin B12, but not to those of vitamin B12 analogues inactive for humans.

A lowered subjective evaluation of the taste and flavor of beer due to staleness or to the addition of an unpleasant taste and flavor was found to be closely correlated with the urination rate. Beer in the same lot was compared immediately after shipment from the brewery and after leaving at room temperature for 1 month or 5 months. Each beer sample was given to volunteers at the rate of 3 ml/kg/15 min for 2 hours, and the urine volume was measured every 30 minutes. The urination rate was highest from the volunteers who drank fresh beer and lowest from those who drank 5-month-old beer. The subjective evaluation of both the taste and drinkability of 5-month-old beer was significantly lower than that of fresh beer. Beer samples with various unpleasant taste and flavor substances added lowered the urination rate. The results suggest that the perception of an unpleasant taste and off-flavor would lower the urination rate.

We have reported an inhibitory effect of Lactobacillus gasseri OLL2809 (OLL2809) on the growth of mouse endometrial tissue in the abdominal cavity. The present study aimed to investigate the efficacy of Lactobacillus gasseri OLL2809 (OLL2809) on pre-existing endometriosis implanted on the abdominal wall in diestrus Wistar-Imamichi female rats. One week after implantation, the volume of the endometrial tissue was measured after laparotomy. OLL2809 and dienogest were administered for 4 weeks. OLL2809 significantly enhanced the decrease in the volume (p<0.01) as compared with control. Complete healing was observed in two of nine rats, but in none of the control group. Dienogest did not show significant efficacy. These findings suggest that OLL2809 is useful not only in therapy of pre-existing endometriosis but also in the prevention of the growth of endometrial tissue.

Based on the broad-spectrum antiviral effect of green tea catechins, we established an experimental skin contact model for influenza virus transmission and evaluated the use of a green tea solution as a first-hand disinfectant. The infectivity of the virus on the skin cell layer became obsolete when washed with the green tea solution. The skin contact model could be applied to develop non-pharmaceutical intervention measures for reducing human transmission of the influenza virus.

A Bacillus subtilis plasmid encoding a green fluorescence protein gene (gfp) was constructed. The fluorescence of B. subtilis colonies having this plasmid on agar plates was so high that they could be readily discerned visually under UV light. The fluorescence could be effectively expressed in three ways (i) through use of a strong bsr promoter (blasticidin S resistance gene), (ii) by efficient translation with the bsr translation system, and (iii) through increase in the copy number per cell. The high stability of the GFP plasmid was demonstrated by using more complicated growth conditions without any antibiotic for selection.

The water-soluble fraction of kale (Brassica oleracea L. var. acephala DC.) had immunoglobulin (Ig) production stimulating activity in human hybridoma HB4C5 cells and human peripheral blood lymphocytes. The biochemical and physical properties of the main active substance in kale were found to be a heat-stable protein with a molecular weight higher than 50 kDa. The Ig production-stimulating factors were assumed to act on the translational and/or secreting processes of Igs. This Ig production-stimulating effect was also observed in lymphocytes from the mesenteric lymph node and Peyer’s patches of mice that had been administered with the kale extract for 14 d. The partially purified kale extract was analyzed by LC-ESI-MS/MS, the result indicating ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) as an active substance. Rubisco from spinach indeed exhibited Ig production-stimulating activity in HB4C5 cells. These findings provide another beneficial aspect of kale as a health-promoting foodstuff.

The water sorption kinetics of dried pasta were measured in the 20–90 °C range in 1.83 mol/L of NaCl and at 80 °C in 1.83 mol/L of LiCl, KCl, NaBr and NaI solutions in order to elucidate the role of salt in the kinetics. At the temperatures higher than 70.8 °C, the change in the enthalpy of sorption, ΔH, in the 1.83 mol/L NaCl solution was 33.1 kJ/mol, which was greater than the ΔH value in water, and the activation energy for the sorption, E, in the salt solution was 25.6 kJ/mol, which was slightly lower than the E value in water. The Hofmeister series of ions was an index for their effect on the equilibrium amount of the sorbed solution of pasta. The apparent diffusion coefficient of water into pasta was not correlated with the crystal radius of the salts, but was with the Stokes radius of the hydrated ions. Equations were formulated to predict the amount of sorbed solution under any condition of temperature and NaCl concentration.

The <I>Saccharomyces cerevisiae</I> gene <I>GTS1</I> is pleiotropic. <I>GTS1</I> induction produces a variety of biological phenomena represented by heat tolerance. To clarify the interaction partners of Gts1p, tandem affinity purification and immunoprecipitation were performed. Ssa1p and Ssa2p, members of the 70-kDa heat-shock protein family, were identified. Co-expression of <I>SSA1</I> or <I>SSA2</I> inhibited Gts1p nuclear import. As compared to the wild type, the <I>SSA1</I> and <I>SSA2</I> double-deletion mutant showed enhancement of Gts1p-mediated heat tolerance in the stationary phase, although neither of the single deletions affected heat tolerance, irrespective of <I>GTS1</I> induction. These results indicate that the heat tolerance function of Gts1p is regulated by Ssa1p and Ssa2p. Furthermore, time-dependent production of Ssa1p and Ssa2p revealed that Gts1p controls the production of Ssa1p and Ssa2p, and that the total amounts of Ssa1p and Ssa2p are important in inhibiting the unique function of Gts1p.

The effects of dietary Yamabushitake mushroom (Hericium erinaceus) on lipid metabolism were examined. C57BL/6J mice were fed a high-fat diet containing hot-water extract (HW-E) and an ethanol extract (EtOH-E) of Yamabushitake mushroom. Administration of HW-E or EtOH-E with a high-fat diet for 28 d resulted in a significant decrease in body weight gain, fat weight, and serum and hepatic triacylglycerol levels. Our in vitro experiments indicated that EtOH-E acts as an agonist of peroxisome proliferator-activated receptor α (PPARα). Quantitative analyses of hepatic mRNA levels revealed that EtOH-E administration resulted in up-regulation of mRNA for a number of PPARα-regulating genes in spite of the fact that the gene expression of PPARα did not change. These results suggest that EtOH-E improves lipid metabolism in mice fed a high-fat diet, and that these effects were mediated by modulation of lipid metabolic gene expression, at least in part via activation of PPARα.

An antitumor antibiotic, ascofuranone, selectively inhibited succinate- and NADPH-dependent O_2 uptake activity of the mito-chondria from Hansenula anomala, suggesting its interaction with the ubiquinone-reduction site of succinate dehydrogenase and external NADPH-dehydrogenase reactions. The action of ascofur-anone on the mitochondria is clearly different from that of antimycin A, the Q_i site inhibitor.

Focusing on a functional component of Momordica charantia, saponin, we investigated its effects on serum glucose and neutral fat levels. Saponin was extracted as a butanol-soluble fraction (saponin fraction) from hot blast-dried Momordica charantia powder. The disaccharidase-inhibitory activity and the pancreatic lipase-inhibitory activity of the saponin fraction were measured, and in vivo sugar- and lipid-loading tests were performed. The saponin fraction inhibited disaccharidase activity and elevation of the blood glucose level after sucrose loading. The fraction also markedly inhibited pancreatic lipase activity and elevation of the serum neutral fat level after corn oil loading. Based on these findings, the main active component related to the anti-diabetic effect of Momordica charantia is present in the butanol fraction, and it may be saponin. The blood glucose and serum neutral fat-lowering effects of Momordica charantia were closely associated with its inhibitory activity against disaccharidase and pancreatic lipase.
