Free iron could easily be chelated with phosphate moiety in biomembrane surface and reduced enzymatically by certain membrane components or non enzymatically by ascorbate.A model membrane lipid peroxidation induced by iron-adriamycin or iron-glycated peptide was discussed. Most probable active species for their lipid peroxidations could be iron oxygen complexes, such as FeV= O and Fe IV=O type compounds. Heme-compounds, hemoglobin, cytochrome P-450 and hematin could mainly act to decompose lipid hydroperoxides to their corresponding alkoxy radicals and hydroperoxy radicals, by which lipid peroxidation should be promoted.

Stress is a part of everyday life, but excessive stress can be related to diverse diseases. Recently, oral intake of a non-centrifuged cane sugar, Kokuto, was reported to produce potential anti-stress effects in humans. However, the molecular components associated with the anti-stress property of Kokuto remain mostly unknown. Therefore, we focused on the non-sugar component (NSC) fractions of Kokuto, and investigated how serum corticosterone level (used as a stress marker) and antioxidant activity were affected in restraint-stressed mice treated with NSC fractions obtained from the elusion on HP-20 resin with 25%, 50%, 75%, and 100% aqueous methanol (MeOH) solutions. Among the four NSC fractions, the 50% MeOH fraction showed a high content of phenolic compounds and high antioxidant activity. Moreover, oral administration of the 50% MeOH fraction suppressed both corticosterone secretion into the serum and reduction of antioxidant activity in serum and liver in restraint-stressed mice. Component analysis of the 50% MeOH fraction identified five antioxidative phenolic compounds: p-hydroxybenzaldehyde, p-hydroxyacetophenone, schaftoside, isoschaftoside, and p-coumaric acid. Phenolic compounds detected in the NSC fractions of Kokuto might contribute to the anti-stress property of Kokuto. In addition, this research provides more understanding of potential health benefits offered by the constituents of Kokuto.

The surface properties and the tactile texture of human hair are important in designing hair-care products. In this study, we evaluated the temporal changes of friction and temperature during the drying process of wet human hair containing water, silicone oil, or oil-in-water (O/W) emulsion. The wet human hair including water or O/W emulsion have a moist feel, which was caused by the temperature reduction of approximately 3-4°C. When human hair is treated with silicone oil, more than 60% of the subjects felt their hair to be slippery and smooth like untreated hair. Treating hair with O/W emulsion after drying made the subject perceive a slippery feeling because the surfactant reduced friction on the hair surface. These results indicated that both friction and thermal properties of the hair surface are important to control the tactile texture of the human hair.

The role of fish oil, primrose oil and their mixture in ameliorating the changes in Alzheimer’s like model was evaluated in rats. Primrose oil and primrose/fish oil mixture fatty acids composition was assessed by gas chromatography. The rat experiment consisted of 5 groups; the first fed on balanced diet as control normal (CN); the other four groups treated with intraperitoneal aluminum lactate and consumed dyslipidemic diet; one group served as control Alzheimer’s like disease (CA) while the other three groups (test groups) received daily oral dose from primrose oil, fish oil and primrose/fish oil mixture separately for 5 weeks. Results showed primrose oil and primrose/ fish oil mixture to contain gamma linolenic acid as 9.15 and 4.3% of total fatty acids, respectively. Eicosapentaenoic and docosahexaenoic were present as 10.9 and 6.5 %, respectively in the oil mixture. Dyslipidemia and increased erythrocyte sedimentation rate (ESR), plasma butyrylcholinesterase (BChE), brain malondialdehyde (MDA) and NO with decrease in plasma magnesium, brain catalase, reduced glutathione, body weight gain and brain weight were demonstrated in CA compared to CN. Brain histopathology and immuno-histochemistry showed neuronal degeneration and neurofibrillary tangles with elevated myeloperoxidase and nuclear factor-kappa B in CA compared to CN. The tested oils demonstrated neuro-protection reflected in the variable significant improvement of biochemical parameters, immuno-histochemistry and brain histopathology. Primrose/fish oil mixture was superior in reducing ESR, brain MDA, plasma activity of BChE and brain histopathological changes along with elevating plasma magnesium. Primrose/fish oil mixture and fish oil were more promising in improving plasma high density lipoprotein cholesterol (HDL-C) than primrose. Fish oil was the most efficient in improving plasma total cholesterol (T-C), low density lipoprotein cholesterol and T-C /HDL-C. Primrose/fish oil mixture and primrose oil were superior in elevating brain catalase compared to fish oil. Other parameters were equally improved by the different oil treatments. Primrose oil, fish oil and their mixture reduced the progression of Alzheimer’s disease in rats with superiority to primrose/fish oil mixture.

In our previous study, the health benefits of the 1975 Japanese diet were shown to be the highest, since the diet suppressed visceral and liver fat accumulation, and hyperglycemia. In addition, the 1975 Japanese diet promoted maintenance of learning memory ability and a lengthened life span. However, the effect of the 1975 Japanese diet has not been ascertained in humans. In the current study, a diet with the characteristics of the 1975 Japanese diet was prepared to examine if this diet is beneficial for human health. The purpose of this randomized controlled trial was to determine effects of the 1975 Japanese diet (JD) in comparison with a modern Japanese diet (MD). Subjects aged 20~29 years old were randomly assigned to the MD (n=16) and JD (n=16) groups. Each subject consumed the diet three times a day for 28 days. Changes in physical conditions, including body composition and blood biochemistry, from before to after the study period were evaluated. As a result, body weight (p < 0.05), body fat percentage (p < 0.05), body fat mass (p < 0.05), serum triglyceride level (p < 0.05), and serum low-density lipoprotein cholesterol level (p < 0.05) were significantly decreased and serum high-density lipoprotein cholesterol (p < 0.05) and serum magnesium levels (p < 0.05) were significantly increased in JD group. These results showed that a diet with the characteristics of the 1975 Japanese diet has a beneficial effect on lipid metabolic parameters.

This study aimed to determine the efficiency of ultraviolet (UV)-LED cold light treatment on the degradation of aflatoxin (AF)B1 in peanut oils. The peanut oil samples obtained from different places in China and abroad were determined for AFB1 degradation efficiency of the UV-LED cold-light irradiation method. The degradation products were analyzed by ultra-high performance liquid chromatography coupled to quadrupole orbitrap high-resolution mass spectrometry (UPLC-Q-Exactive MS). The results indicated that the AFB1 content in all peanut oil samples decreased rapidly after 5 min of irradiation. Four main photodegradation products (C18H16O7, C17H14O7, C17H14O7, and C17H14O8) were identified using the established LC-MS method. Their chemical structures were postulated based on the LC-MS data. Also, the degradation pathways were proposed based on the data obtained. Oxidation and reduction reactions were mainly responsible for AFB1 decomposition. The reactions occurred at the furan and lactone rings. These findings demonstrated that UV-LED cold-light irradiation was an effective method for treating AFB1-contaminated peanut oil.

The purpose of this study is to determine whether the complexing hydroalcoholic extract of Cuscuta reflexa (HECR) with phosphatidyl choline increases its bioavailability. As a result, a novel phytosomal delivery system for the HECR-soya lecithin complex was developed (HECR-phytosome). The HECR-phytosome complex was synthesized and characterized as phytovesicles. The formulation was prepared using a variable concentration of soya lecithin (1:1-1:3 percent w/v), a temperature range of (45-65°C), and sonication time (4-8 min). Optimization of HECR-loaded phytosomal formulations was performed using Design Expert software. A three-factor, three-level Box-Behnken design was used to optimize this HECR delivery system, as dependent variables, vesicular size and entrapment efficiency were evaluated using a Box Behnken factorial design. Further characterization of the optimized formulation included vesicle size, PDI, zeta potential, entrapment efficiency, FTIR, DSC, TEM, and in vitro release. Vesicle sizes ranged from 173.5±6.17 nm to 215.9±6.53 nm, and response rates for entrapment efficiency ranged from 52.9±1.65 to 77.2±1.1%. The uniform structure and spherical shape were demonstrated by transmission electron microscopy. Among the drug release kinetic models, the formulation followed the Higuchi model (R2 = 0.9978), releasing 96.3±3.7% of the polyphenol and flavonoids phytoconstituents from HECR-loaded phytosomes in 12 hours, compared to 49.3±2.5% in the plain extract. In addition, the optimized formulation passes the stability test. Therefore, the results demonstrated that phytosomal nanocarriers have the potential to increase the bioavailability of Cuscuta reflexa extract.

The friction characteristics of foaming body cleansers determine skin physical irritation, as well as the usability of the products. In this study, the friction of foam formed by a commercial body cleanser was evaluated using a sinusoidal-motion friction evaluation system. The friction profile of the foam was a hydrodynamic stable pattern, where the friction force increased with increasing velocity. In addition, soapbased cleansers, containing polyols, showed large friction coefficients. These properties suggest that the mechanical properties of the interfacial film and viscosity of the cleanser bulk affect friction properties. These findings assist in controlling the texture of body cleansers.

Current experimental techniques for estimation of the cell surface tension by contact angle measurements were reviewed. It is shown that in the process of measuring the contact angles of drops of water or air bubbles at biological surfaces, transfer of natural surface active materials to the air/water interface occurs with a consequent reduction in the surface tension. The estimation of cell surface tensions from contact angles based on theoretical calculations in which the air/water tension of pure water is used are in error. The adhering bubble method is preferable for contact angle determinations in biological systems.

A high-fat diet is believed to be a risk factor for hypertension through inducing obesity. It has been reported that variants of the fat mass and obesity-associated (FTO) and beta-3 adrenergic receptor (B3AR) genes are associated with obesity and blood pressure. The purpose of this study was to investigate the effect of dietary fat on blood pressure with or without the variant of the FTO and B3AR genes. A total of 227 healthy Japanese women aged 18 to 64 years were recruited for measurement of nutrient intake and blood pressure. The single nucleotide polymorphism rs9939609 of the FTO gene and rs4994 of the B3AR gene were genotyped. Spearman’s rank correlation coefficient was applied to investigate the relationship between fat intake and blood pressure. A hierarchical multiple regression analysis was performed to determine whether the genotype interacts with fat intake to affect blood pressure. No significant correlations were found between fat intake and either systolic or diastolic blood pressure. A significant negative correlation was found between fat intake and both blood pressures in the FTO-gene-variant group, but not in the normal-FTO-gene group. In hierarchical multiple regression analysis, the interaction of fat intake and the gene variant showed significance, and the change in coefficient of determination (R2) was significantly increased with increases of the interaction variable. These results indicate that the effect of fat intake on blood pressure may be modified by the variant of the FTO gene such that a high-fat diet intake may be associated with a decrease of systolic and diastolic blood pressure in healthy Japanese women with the FTO variant. Our results did not support the hypothesis that a high-fat diet increases blood pressure.

Precision nutrition, also referred to as personalized nutrition, focuses on the individual to determine the individual’s most effective eating plan to prevent or treat disease. A precision nutrition for infants requires the determination of the profile of human milk. We compared the lipid profiles of the foremilk (i.e., the initial milk of a breastfeed) and hindmilk (the last milk) of six Japanese subjects and evaluated whether a human milk lipid profile is useful for precision nutrition even though the fat concentration fluctuates during lactation. We detected and quantified 527 species with a lipidome analysis by liquid chromatography-tandem mass spectrometry. The fat concentration in hindmilk (120.6 ± 66.7 μmol/mL) was significantly higher than that in foremilk (68.6 ± 33.3 μmol/mL). While the total carbon number of fatty acids in triglyceride (TG) was highest in C52 for all subjects, the second or third number differed among the subjects. Both the distribution of total carbon number of fatty acids included in TG and the distribution of fatty acids in TG classified by the number of double bonds were almost the same in the foremilk and hindmilk in each subject. The lipids levels containing docosahexaenoic acid and arachidonic acid in total lipids of the foremilk and the hindmilk were almost the same in each subject. Among the sphingolipids and glycerophospholipids, the level of sphingomyelin was the highest in four subjects’ milk, and phosphatidylcholine was the highest in the other two subjects’ milk. The order of their major species was the same in each foremilk and hindmilk. A clustering heatmap revealed the differences between foremilk and hindmilk in the same subject were smaller than the differences among individuals. Our analyses indicate that a human-milk lipid profile reflects individual characteristics and is a worthwhile focus for precision nutrition.

Medium-chain triglycerides (MCT) are useful for increasing fat utilization during exercise. The highest rate of fat oxidation during submaximal exercise tends to precede the lactate threshold in untrained adults. In our previous study, blood lactate concentration was more than 4 mmol/L (onset of blood lactate) in recreational athletes during exercise at a workload corresponding to 60% peak O2 uptake (V・o2), which was below ventilation threshold. In the present study, we investigated the effect of 2 week of ingestion of food containing 6 g MCT on substrate oxidation during moderate-intensity (50% peak V・o2) exercise and high-intensity (70% peak V・o2) exercise in recreational athletes. For comparison, two experimental trials were conducted after participants had been administered isoenergic test foods (MCT-supplemented food with mainly maltodextrin-containing carbohydrate (MCT + CHO) or CHO) for 2 weeks, with a washout period between trials. Participants were instructed to perform cycle ergometer exercise at a workload corresponding to 50% peak V・o2 for 40 min followed by a workload corresponding to 70% peak V・o2 until exhaustion. Fat oxidation was significantly increased in the MCT + CHO trial (13.3 ± 2.7 g/40 min, mean ± SD, p < 0.05) during moderate-intensity exercise and the duration was extended significantly (23.5 ± 19.4 min, p < 0.05) during subsequent high-intensity exercise, compared with that observed in the CHO trial (fat oxidation; 11.7 ± 2.8 g/40 min, duration; 17.6 ± 16.1 min). In conclusion, continuous ingestion of 6 g MCT with maltodextrin could increase fat oxidation during moderate-intensity exercise and extend the duration of subsequent high-intensity exercise in recreational athletes, compared with the ingestion of isoenergic maltodextrin alone.
