Summary : We have identified five phytosterols （ Aloe sterols ） obtained from Aloe vera gel as functional ingredients. In this study, we investigated the effects of orally ingested Aloe sterols on skin function, which is impor-tant for body homeostasis. In an in vitro study, the synthesis and production of collagen and hyaluronan by fibroblasts isolated from human skin were stimulated by addition of Aloe sterols. Aloe sterol supplementation in vivo also suppressed UV-induced reductions of skin hydration, elasticity and dermal collagen content signifi-cantly. We then performed a 12 -week double blind, randomized controlled trial of daily oral intake of Aloe sterols, and observed significant increases in skin barrier function, skin moisture, skin elasticity and dermal collagen content. The results of these studies confirmed the usefulness of Aloe sterols as functional food material for maintenance and promotion of skin health.

Summary : Seaweed is a popular and traditional Japanese food rich in various minerals and vitamins, as well as dietary fibre. However, its effects on human lipid metabolism are poorly understood. We aimed to evaluate the effect of wakame, the Japanese name for the brown seaweed Undaria pinnatifida , on postprandial serum lipid responses to consumption of a high-fat diet in humans. In a randomized crossover trial, 10 women with nor-molipidemia or mild hypertriglyceridemia were administered a high-fat diet containing approximately 40 . 6 g of lipid with or without 4 g of dried wakame. Serum lipid levels were measured in the fasting state and 2 , 3 , 4 , 6 hours after consuming the high-fat diet. With reference to the control group, intake of wakame suppressed the elevation of serum remnant like particle-cholesterol (RemL-C) (at 6 hours), and lipoprotein (Origin) (at 4 hours) levels. In conclusion, this trial demonstrated that wakame consumption attenuates the postprandial in-crease in serum TG, RemL-C, and CM levels following a fat load, suggesting its potential role in reducing the risk of arteriosclerotic diseases.

Summary : This study examined the associations between subjective psychosomatic symptoms (SPS) and dietary intake, as well as lifestyle habits, among middle school students by analyzing the results of a cross-sectional survey. Between August 2016 and January 2017 , study participants from 12 middle schools ( n ＝1 , 625 , 813 boys and 812 girls, aged 12-14 years) were recruited from all eligible participants in M-city, Japan. The parents or guardians of the students provided informed consent. School nurses measured the students ʼ body weight and height. Two self-administered questionnaires were used: one to investigate dietary intake (FFQW 82 ) and the other to investigate lifestyle habits, health status, and SPS. The responses of 1 , 465 students were analyzed (response rate 90 . 2％ ). The results showed that daily energy intake (kcal) tended to be larger at dinner than at breakfast; the intake ratio of the 3 main meals, i.e. breakfast, lunch, and dinner, was 2 : 3 : 4 . This suggested that intake at breakfast was insufficient and that at dinner was excessive. Comparison of food groups showed that calorie intake in the meat group was more than double that in the fish and shellfish group, whereas intake in the vegetable group fell below the target value ( 350 g per day). Fewer than half of both boys and girls avoided intake of large amounts of fatty foods ( 34 . 9％ , 34 . 8％ ), and ate both the main dish ( 34 . 3％ , 29 . 9％ ) and vegetables ( 25 . 1％ , 24 . 2％ ) for breakfast. Application of regression models showed that the following factors were significantly associated with a low SPS score for both boys and girls: dietary intake of fiber ( p ＝0 . 011 , p ＜ 0 . 001 ), going to sleep before midnight ( p ＝0 . 006 , p ＜ 0 . 001 ), and sleeping 6 hours or more per day ( p ＜0 . 001 , p ＝0 . 018 ). Conversely, confectionaries/high sugar beverages were significantly associated with a high SPS score for boys and girls ( p ＜0 . 001 , p ＝0 . 001 ). Taken together, these findings suggest that SPS are associated with dietary intake and lifestyle habits in middle school students.
摘要:本研究通过横断面调查分析中学生主观心身症状(SPS)与饮食摄入和生活习惯之间的关系。在2016年8月至2017年1月期间，从日本M-city的所有符合条件的参与者中招募了来自12所中学的研究参与者(n = 1,625,813名男孩和812名女孩，年龄在12-14岁)。学生的家长或监护人提供知情同意。学校护士测量了学生的体重和身高。采用两份自我管理问卷:一份调查饮食摄入(ffqw82)，另一份调查生活习惯、健康状况和SPS。对1465名学生的回答进行了分析(回复率为90。2％ ). 结果表明，晚餐时的每日能量摄入(千卡)往往大于早餐时;早餐、午餐、晚餐三顿主餐的摄入比例为2:3:4。这表明早餐摄入不足，而晚餐摄入过量。食物组的比较表明，肉类组的卡路里摄入量是鱼类和贝类组的两倍多，而蔬菜组的摄入量低于目标值(每天350克)。不到一半的男孩和女孩都避免摄入大量高脂肪食物。9％ , 34 . 8%)，并把主菜都吃了(34%)。3％ , 29 . 9%)和蔬菜(25%)。1％ , 24 . 2%)作为早餐。回归模型的应用表明，以下因素与男孩和女孩的低SPS评分显著相关:膳食纤维摄入量(p = 0.05);011, p < 0。001)，在午夜前睡觉(p =0)。006, p < 0。0.001)，每天睡眠6小时或更长时间(p < 0.05)。001, p =0。018)。相反，糖果/高糖饮料与男孩和女孩的高SPS得分显著相关(p < 0.05)。001, p =0。001)。综上所述，这些发现表明SPS与中学生的饮食摄入和生活习惯有关。

Summary : Staphylococcus aureus is a resident bacterium in healthy humans. However, methicillin-resistant S. aureus (MRSA) is a major causative bacterium of nosocomial infectious diseases. In addition, the enterotoxin produced by S. aureus causes food poisoning. In this study, we searched for components within the juice of aronia ( Aronia melanocarpa ) that would exert antibacterial activity against the growth of S. aureus . To search these active components, we carried out different extraction methods. We found that the water-soluble components of freeze-dried aronia juice had a strong antimicrobial effect against S. aureus strains. To search for the active in-gredients, we carried out fractionation of aronia juice by reverse-phase chromatography and examined the antibacterial effects of fractions eluted with 20-30 % acetonitrile. Mass spectrometry identified some low-molecular-weight compounds ― chlorogenic acid, protocatechuic acid, and gentisic acid ― as components of aronia.
