Background: As alcohol consumption increases, ethanol impacts ulcers as a factor that causes stomach mucosal invasion, which leads to stomach ulcers. Alcohol damages the stomach through a number of processes, including increased gastric secretion, the release of pro-inflammatory cytokines, and ethanol induces a variety of pathogenic events as it is associated with the formation of stomach ulcers.Objective: The goal of this study was to see if gum Arabic as a functional food could protect albino rats against ethanol-induced stomach damage.Materials and Methods: Six groups of 30 female albino rats were formed: normal control, ulcer control, omeprazole + ethanol, and groups 4, 5, and 6, which were given GA at 7.5, 12, 25 g/ kg/ day (bw), then lab rat were given 5 mL/kg /day (bw) ethanol orally for 30 days to cause stomach mucosal damage.Results: GA suppressed gastric inflammation by lowering TNF-α and IL-6 levels while increasing IL-10 levels. GA also improved HDL, total protein, albumin, and globulin levels while lowering cholesterol, triglycerides, VLDL-C, LDL-C, and phospholipids.Conclusion: These findings demonstrate that GA plays a protective role toward gastric mucosal injury in rats induced by ethanol, which in turn reduced the inflammatory response, and significantly reduced the hemorrhagic gastric lesions and the pH of the gastric contents. Keywords: Functional food, Alcoholic, polysaccharides, soluble fiber, tumor necrosis factor alpha, oxidative stress 
背景:随着饮酒量的增加,乙醇会影响溃疡,成为导致胃黏膜侵袭的因素,从而导致胃溃疡。酒精通过许多过程损害胃,包括胃分泌增加、促炎细胞因子的释放,以及乙醇诱导各种致病事件,因为它与胃溃疡的形成有关。目的:本研究的目的是观察阿拉伯树胶作为一种功能性食品是否能保护白化大鼠免受乙醇诱导的胃损伤。材料和方法:30只雌性白化大鼠分为6组:正常对照组、溃疡对照组、奥美拉唑+乙醇组,第4组、第5组和第6组,分别给予7.5、12、25 g/kg/天(bw)的GA,然后给实验大鼠口服5 mL/kg/天(bw)的乙醇,持续30天,造成胃粘膜损伤。结果:GA通过降低TNF-α和IL-6水平,同时增加IL-10水平来抑制胃炎症。GA还能提高高密度脂蛋白、总蛋白、白蛋白和球蛋白水平,同时降低胆固醇、甘油三酯、极低密度脂蛋白胆固醇、低密度脂素胆固醇和磷脂。结论:GA对乙醇诱导的大鼠胃黏膜损伤具有保护作用,从而减轻炎症反应,显著降低胃出血性病变和胃内容物的pH值。关键词:功能性食品,醇类,多糖,可溶性纤维,肿瘤坏死因子α,氧化应激

Background: The nutritional composition of the bran layer of rice (RB), a globally available product of the rice milling process, has attracted attention as a nutraceutical food source. However, to capitalize on RB’s nutritional properties for humans, it is necessary to achieve a level of bioavailability that increases the efficacy needed to impact the nutritional well-being of lactating mothers and their breastfed infants. To accomplish this, a hydrolyzed enzymatic extract (RBEE) with increased protein, vitamin, carbohydrate, and antioxidant bioactivity has been developed.Objective: To determine the impact of RBEE on the nutritional status of lactating mothers (LM) and the growth of their exclusively breastfed (EBF) infants, living in food-insecure environments in rural Guatemala. Methods:  A RBEE daily ration was consumed by post-puerperium LM for 4.5 months of the EBF period. The nutritional impact on LMs was determined by body mass index (BMI). Anemia prevalence and packed cell volume (PCV) were obtained via hematocrit (HCT). Infant growth was determined monthly following World Health Organization (WHO) guidelines, including weight-for-length (WHZ), weight-for-age (WAZ), length-for-age (LAZ), BMI-for-age (BAZ) and head circumference-for-age (HCZ). Initial, midterm and final growth indicators were analyzed by Student t-test for independent samples. Results: While no significant differences were found between the initial and final BMI in LMs, anemia prevalence was significantly reduced from 12.1% to 4%. HCT results in LMs showed a significant increase (p<0.05) in PCV by the study’s end, from 40.55% to 41.42%. Following a student t-test analysis, infant growth indicators WHZ, WAZ and BAZ showed a highly significant (p<0.01) increase. A significant (p<0.05) improvement was detected in WAZ, while LAZ scores improved from -1.9 to -1.76.Conclusions: The dietary supplementation of lactating mothers with an RBEE during the EBF period significantly impacted the mother-infant dyad, with improved growth of the exclusively breastfed infants and a reduction in anemia prevalence in mothers. Further research will include the quantity and quality of the putative increased maternal milk synthesis.  Keywords: rice bran, bioactive, bioavailability, enzyme-treated extract, functional food, infants, exclusive breastfeeding, lactating mothers, anemia, chronic, acute, malnutrition, Guatemala, growth, nutrition, children.
背景:米糠层的营养成分作为一种营养保健食品来源已引起人们的关注,它是一种全球可用的碾米加工产品。然而,为了充分利用RB对人类的营养特性,有必要达到一定程度的生物利用度,以提高影响哺乳期母亲及其母乳喂养婴儿营养健康所需的功效。为了实现这一目标,已经开发出一种具有增加蛋白质,维生素,碳水化合物和抗氧化生物活性的水解酶提取物(RBEE)。目的:确定RBEE对生活在危地马拉农村粮食不安全环境中的哺乳期母亲(LM)营养状况及其纯母乳喂养(EBF)婴儿生长发育的影响。方法:在4.5个月的EBF期间,产后LM每天食用RBEE定量饲料。通过体重指数(BMI)确定营养对LMs的影响。通过红细胞压积(HCT)获得贫血发生率和堆积细胞体积(PCV)。根据世界卫生组织(WHO)的指导方针,包括体重与身高(WHZ)、体重与年龄(WAZ)、身高与年龄(LAZ)、体重与年龄(BAZ)和头围与年龄(HCZ),每月测定婴儿生长。独立样本的初始、中期和最终生长指标采用学生t检验进行分析。结果:虽然LMs的初始和最终BMI没有显著差异,但贫血患病率从12.1%显著降低到4%。研究结束时,LMs的HCT结果显示PCV显著增加(p<0.05),从40.55%增加到41.42%。经学生t检验分析,婴儿生长指标WHZ、WAZ和BAZ均呈极显著升高(p<0.01)。WAZ评分显著提高(p<0.05), LAZ评分从-1.9分提高到-1.76分。结论:在EBF期间,母乳喂养的母亲在饮食中添加RBEE显著影响了母婴双体,改善了纯母乳喂养婴儿的生长,降低了母亲贫血的患病率。进一步的研究将包括假定增加的母乳合成的数量和质量。关键词:米糠,生物活性,生物利用度,酶处理提取物,功能食品,婴儿,纯母乳喂养,哺乳期母亲,贫血,慢性,急性,营养不良,危地马拉,生长,营养,儿童。

Background: Excessive ingestion of fructose can lead to obesity and related diseases. Eucalyptus leaf extract (ELE) contains oenothein B, which inhibits intestinal fructose absorption.Objective: The antiobesity effects of ELE containing oenothein B were evaluated in healthy Japanese whose body mass index (BMI) was ≥ 23 and < 30 kg/m2.Methods: A randomized, placebo-controlled, double-blind, parallel-group study was performed to evaluate the effect of ELE consumption, for 12 weeks at a 3.38 mg/day dose of oenothein B, on the abdominal visceral fat area (VFA) as the primary outcome. Results were compared to those of a placebo group.Results: Of the 721 individuals who underwent screening, 198 were randomly allocated into two groups. A total of 95 subjects in the placebo group and 94 in the intervention group were established as the per-protocol set. VFA in the intervention group significantly decreased compared to that in the placebo group 12 weeks after initiating intervention. This reduction in VFA was considered to have clinical significance. Among the secondary outcomes, VFA, waist circumference, and muscle mass after 8 weeks, as well as body weight and BMI after 12 weeks, were significantly lower in the intervention group compared to the placebo group.Conclusion: ELE containing oenothein B may be effective against obesity and related diseases by reducing VFA levels. Keywords: human trial; Eucalyptus globulus; oenothein B; polyphenol; hydrolyzable tannin; ellagitannin; dietary fructose consumption; dietary survey; Calorie and Nutrition Diary; glucose transporter 5

Introduction: Undenatured type II collagen, derived from chicken sternum cartilage, is a novel functional ingredient, which has been demonstrated to improve joint health, flexibility and mobility, and enhancing motor functions. Undenatured type II collagen has been commercially available as functional dietary supplement worldwide for many years. Research studies demonstrated its broad-spectrum safety and clinical efficacy. Undenatured type II collagen requires very small amount to exhibit clinical efficacy and hence can be easily consumed over a long period of time as compared to the other joint care functional ingredients such as glucosamine and chondroitin. Since undenatured type II collagen is effective in relatively small amount, its accurate measurement in various dosage forms such as tablets and capsules become crucial to provide consumers optimal cost and joint-health benefits. Objective: In the present study, we modified the previously used Enzyme-Linked Immunosorbent Assay (ELISA) method to determine the active constituents precisely and accurately in formulations to affirm broad spectrum safety and clinical efficacy. Methods: Improved precision ELISA methodology was utilized to determine the amount of undenatured type II collagen extracted from chicken sternum cartilage. A commercially available Chondrex Collagen Detection Kit was used to determine the number of epitope (antigenic determinant) sites on the three-dimensional tightly-folded structured collagen. Time and temperature were set at ≥16 h or preferably within the range of 16 h to 24 h and at room temperatureResults: The results obtained from this improved ELISA method strongly supported the accuracy and validity, which correlates very well with the results of our earlier clinical studies, revealing the efficacy of undenatured type II collagen concentrations used. Furthermore, the modified ELISA method, designed by our team, revealed consistent and reproducible results on the basis of counting the epitope sites in undenatured type II collagen (NEXT-II®) of commercial batchesConclusion: Using this precisely modified ELISA method gave 8% of undenatured type II collagen in NEXT-II®, resulting in 3.2 mg in 40.0 mg of NEXT-II®. It also confirmed that administration of 3.2 mg of undenatured type II collagen a day, both in open-label and randomized clinical trials, was safe and efficacious for joint pain, flexibility and mobility, and motor function. Keywords: Undenatured type II collagen, NEXT-II®, ELISA method, Pepsin
简介:来源于鸡胸骨软骨的未变性II型胶原是一种新型功能成分,已被证明可以改善关节健康、灵活性和灵活性,并增强运动功能。未变性的II型胶原作为功能性膳食补充剂已在世界范围内商业化多年。研究表明其具有广谱安全性和临床疗效。与其他关节护理功能成分如葡糖胺和软骨素相比,未变性的II型胶原需要非常少量才能发挥临床功效,因此可以很容易地在很长一段时间内消耗掉。由于未变性的II型胶原蛋白的有效量相对较小,因此准确测量片剂和胶囊等各种剂型的胶原蛋白对于为消费者提供最佳成本和关节健康益处至关重要。目的:在本研究中,我们修改了以前使用的酶联免疫吸附法(ELISA),以准确准确地测定制剂中的活性成分,从而确认广谱安全性和临床疗效。方法:采用改良精密ELISA法测定鸡胸骨软骨中未变性Ⅱ型胶原的含量。使用市售Chondrex胶原检测试剂盒测定三维紧密折叠结构胶原上的表位(抗原决定簇)位点的数量。时间和温度设置为≥16小时,或优选在16小时至24小时的范围内,并在室温下。结果:从这种改进的ELISA方法获得的结果有力地支持了准确性和有效性,这与我们早期的临床研究结果非常相关,揭示了所用未变性II型胶原浓度的有效性。此外,我们团队设计的改良ELISA方法在计算商业批次的未变性II型胶原(NEXT-II®)中的表位位点的基础上,显示了一致且可重复的结果。它还证实,在开放标签和随机临床试验中,每天服用3.2毫克未变性的II型胶原,对关节疼痛、灵活性和灵活性以及运动功能都是安全有效的。关键词:未变性II型胶原,NEXT-II®,ELISA法,胃蛋白酶

Introduction: In previous work, we have shown the synergistic effects of combinations of vitamins A, D2, and D3 in reducing the proliferation of HCT-116 colon cancer cells. This combination also induced apoptosis and altered gene expression patterns as determined by transcriptomic profiling. Aims: The aims of this study were to investigate the effects of vitamins A and D in HCT-116 Crl:NU(NCr)-Foxn1nu mouse xenographs. Also, to determine potential mechanisms of action using miRNA-seq and correlated these data with results from RNA-seq.Methods: HCT-116 colon cancer cells were cultured and used for the xenograph study. Crl:NU(NCr)-Male Foxn1nu mice were injected subcutaneously with HCT-116-cells (1 X 106 in 100 µl 50% Matrigel and Sterile PBS), and after 7 days, were treated with vitamin A and D in feed for 21 days. The mice were imaged on day 28, sacrificed and the tumors were excised and measured. RNA was isolated from the HCT-116 cells and tumors, and RNA-seq and miRNA-seq were performed.Results: There was a concentration-dependent reduction in the HCT-116 colon cancer cell viability after treatment with vitamin A and D combinations. In Crl:NU(NCr)-Foxn1nu mice injected with HCT-116 colon tumor cells, treatment with vitamin A (25,000 IU) and vitamin D (4,000 IU) or vitamin A (35,000 IU) and vitamin D (5,000 IU) for 21 days significantly reduced tumor growth by ~38% and ~58%, respectively (p < 0.001). In the HCT-116 cells and excised tumors, treatment upregulated the expression of Bim, Bax, p53, and PTEN, and downregulated AXIN2, ID2 and DDX20 mRNAs, all well-known pro-apoptotic proteins, tumor suppressors, and molecules involved in the epithelial-mesenchymal transition. Ingenuity Pathway Analysis of miRNA-seq paired with RNA-seq showed correlations between miRNAs expression and expression of these genes. For example, miRNA-mRNA correlation pairing showed that treatment downregulated miR-30c-3p and miR-125b-3p which was associated with upregulated TP53. Upregulation of the tumor suppressor PTEN was associated with the downregulation of eleven miRNAs, including oncogenic miR17 and miR21.Conclusion: The results suggest that the combinations of vitamins A and D reduced the HCT-116 tumor burden in mice and altered the expression of miRNAs directly associated with genes in the apoptosis, tumor suppression, and epithelial-mesenchymal transition pathways. The data supports the hypothesis that vitamin A and D combinations impact multiple cancer signaling pathways and thus may be more effective in the treatment and prevention of cancer, as well as reducing cancer metastasis.   Keywords: apoptosis, cholcalciferol, colon cancer, DDX20, epithelial-mesenchymal transition, ergocalciferol, p53, RNA-seq, miRNA-seq, PTEN, synergism, transcriptome
简介:在之前的工作中,我们已经显示了维生素A、D2和D3的组合在减少HCT-116结肠癌癌症细胞增殖方面的协同作用。这种组合还诱导了细胞凋亡,并通过转录组学分析改变了基因表达模式。目的:本研究旨在研究维生素A和D在HCT-116 Crl:NU(NCr)-Foxn1nu小鼠异种移植物中的作用。此外,使用miRNA-seq确定潜在的作用机制,并将这些数据与RNA-seq的结果相关联。方法:培养癌症HCT-116细胞,进行异种移植研究。Crl:NU(NCr)-雄性Foxn1nu小鼠皮下注射HCT-116细胞(在100µl 50%基质胶和无菌PBS中1 X 106),7天后,用饲料中的维生素A和D处理21天。在第28天对小鼠进行成像,处死并切除肿瘤并进行测量。从HCT-116细胞和肿瘤中分离RNA,并进行RNA-seq和miRNA-seq。结果:维生素a和D组合治疗后,HCT-116结肠癌癌症细胞活力呈浓度依赖性降低。在注射HCT-116结肠肿瘤细胞的Cr:NU(NCr)-Foxn1nu小鼠中,用维生素A(25000 IU)和维生素D(4000 IU)或维生素A(35000 IU)与维生素D(5000 IU)治疗21天,肿瘤生长分别显著降低约38%和约58%(p<0.001)。在HCT-116细胞和切除的肿瘤中,治疗上调了Bim、Bax、p53和PTEN的表达,以及下调的AXIN2、ID2和DDX20 mRNA,所有众所周知的促凋亡蛋白、肿瘤抑制剂和参与上皮-间质转化的分子。miRNA-seq与RNA-seq配对的独创性途径分析显示,miRNAs的表达与这些基因的表达之间存在相关性。例如,miRNA-mRNA相关性配对显示,治疗下调了miR-30c-3p和miR-125b-3p,这与上调的TP53有关。抑癌基因PTEN的上调与11种miRNA的下调有关,包括致癌miR17和miR21,以及上皮-间充质转化途径。该数据支持维生素A和D组合影响多种癌症信号通路的假设,因此在治疗和预防癌症以及减少癌症转移方面可能更有效。关键词:细胞凋亡、cholcalciferol、结肠癌癌症、DDX20、上皮间质转化、麦角钙化醇、p53、RNA-seq、miRNA-seq和PTEN、协同作用、转录组

Also, to determine potential mechanisms of action using miRNA-seq and correlated these data with results from RNA-seq.Methods: HCT-116 colon cancer cells were cultured and used for the xenograph study. Crl:NU(NCr)-Male Foxn1nu mice were injected subcutaneously with HCT-116-cells (1 X 106 in 100 µl 50% Matrigel and Sterile PBS), and after 7 days, were treated with vitamin A and D in feed for 21 days. The mice were imaged on day 28, sacrificed and the tumors were excised and measured. RNA was isolated from the HCT-116 cells and tumors, and RNA-seq and miRNA-seq were performed.Results: There was a concentration-dependent reduction in the HCT-116 colon cancer cell viability after treatment with vitamin A and D combinations. In Crl:NU(NCr)-Foxn1nu mice injected with HCT-116 colon tumor cells, treatment with vitamin A (25,000 IU) and vitamin D (4,000 IU) or vitamin A (35,000 IU) and vitamin D (5,000 IU) for 21 days significantly reduced tumor growth by ~38% and ~58%, respectively (p < 0.001). In the HCT-116 cells and excised tumors, treatment upregulated the expression of Bim, Bax, p53, and PTEN, and downregulated AXIN2, ID2 and DDX20 mRNAs, all well-known pro-apoptotic proteins, tumor suppressors, and molecules involved in the epithelial-mesenchymal transition. Ingenuity Pathway Analysis of miRNA-seq paired with RNA-seq showed correlations between miRNAs expression and expression of these genes. For example, miRNA-mRNA correlation pairing showed that treatment downregulated miR-30c-3p and miR-125b-3p which was associated with upregulated TP53.

Background: Several peptides from seafood have shown effective anticancer activities. Nonetheless, one of the most significant challenges in developing fish peptides as functional food ingredients is proving their efficacy as anticancer agents. This study was aimed to evaluate the anticancer capacity and stability of a purified peptide (H. Met-Gly-Pro-Pro-Gly-Leu-Ala-Gly-Ala-Pro-Gly-Glu-Ala-Gly-Arg.OH) during a simulated gastrointestinal (GI) digestion.Methods: The anticancer activity of the peptide(s) before, during, and after GI digestion was analyzed against colon cancer cells (HT-29). Changes in cell morphology were assessed using an inverted microscope, while the degree of apoptosis was observed using a Muse Cell Analyzer.Results: Results showed little or no hydrolysis of the bioactive peptide by pepsin was observed, indicating the peptide was resistant to digestion in gastric conditions. The growth of HT-29 cells was significantly inhibited (P < 0.05) by the un-digested peptide and peptide(s) present in the digesta that was yielded by gastric and gastrointestinal digestion up to 28.89%, 29.68%, and 38.3%, respectively. HT-29 cells treated with pepsin and pancreatin digested peptides showed the highest cell death (3.54±2.30%).Conclusion: Overall, the findings showed that the purified peptide has the potency to be used in cancer therapy via oral administration and/or incorporation in food(s) applications for the treatment of specific cancer.Keywords: bioactive peptide; digestion; fish by-products; hydrolysis

Introduction: Yogurt is mixed with spinach in some countries. Spinach can be a probable dietary source of Nitrate and Nitrite, and further N-nitrosamine. Methods: The present study aimed to investigate the effect of inoculation of Lactobacillus acidophilus on the level of nitrite and nitrate in “yogurt containing spinach” (YS) during refrigeration in for 21 days. 4 types of yogurts including yogurt (Y), probiotic yogurt (PY), YS, and probiotic YS (PYS) were produced and kept at 4 °C for 21 days. Their nitrite and nitrate levels were measured by HPLC on days 1, 7, 14, and 21. Results: There was no significant difference between the mean concentrations of nitrate and nitrite of Y and PY and between YS and PYS. Although the effect of refrigeration at 4 °C for 21 days was not significant on the nitrate amount of Y and PY, it was close to a significant level in YS and PYS. It also caused a significant increase in the nitrite content of all yogurts. This study showed that Lactobacillus acidophilus bacteria cannot affect the amount of nitrate and nitrite in yogurt or YS at 4°C. Conclusion: Increasing the nitrite content of samples may enhance the possibility of nitrosamine formation. It is suggested that those who are at risk for all malformations caused by nitrites should not keep YS for a long time.  Keywords: nitrate; nitrite; Lactobacillus acidophilus; probiotic yogurt containing spinach; HPLC
简介:在一些国家,酸奶是和菠菜混合在一起的。菠菜可能是硝酸盐和亚硝酸盐以及N-亚硝胺的膳食来源。方法:研究接种嗜酸乳杆菌对冷藏21天的“菠菜酸奶”中亚硝酸盐和硝酸盐含量的影响。生产了4种酸奶,包括酸奶(Y)、益生菌酸奶(PY)、YS和益生菌YS(PYS),并在4°C下保存21天。在第1天、第7天、第14天和第21天通过HPLC测定了它们的亚硝酸盐和硝酸盐水平。结果:Y和PY的硝酸盐和亚硝酸盐的平均浓度与YS和PYS之间没有显著差异。尽管在4°C下冷藏21天对Y和PY的硝酸盐含量没有显著影响,但在YS和PYS中接近显著水平。它还导致所有酸奶的亚硝酸盐含量显著增加。该研究表明,嗜酸乳杆菌在4°C下不会影响酸奶或YS中硝酸盐和亚硝酸盐的含量。结论:增加样品中亚硝酸盐的含量可能会增加亚硝胺形成的可能性。建议那些有亚硝酸盐引起所有畸形风险的人不要长期服用YS。关键词:硝酸盐;亚硝酸盐;嗜酸乳杆菌;含有菠菜的益生菌酸奶;HPLC

Background: Daily fatigue is a problem for many people because of its association with other illnesses. Maca has lately attracted considerable attention as a food for recovering from fatigue. Maca is high in benzyl glucosinolate which improves endurance capacity by preventing glycogen depletion. However, its effect on fatigue has not been investigated in clinical trials on humans. Objective: The main objective of this study is to investigate the effects of maca supplements on reducing fatigue.Methods: This study evaluated the effect of the consumption of maca extract containing benzyl glucosinolate (9.6 mg/day) on fatigue in adult women. This randomized, placebo–controlled, parallel–group double–blind study enrolled 60 subjects who were allocated to consume maca extract or placebo for 4 weeks. A visual analogue scale (VAS) for fatigue was used to evaluate the results. Blood variables and adverse events were used to assess safety.Results: In both groups, the VAS of fatigue was decreased after 4 weeks compared with that before consumption. On stratification analysis, in subjects younger than 45 years, the VAS was significantly lower in the maca group, and the change between before and after supplementation was significantly larger in this group. Conclusions: It was suggested that intake of maca extract containing benzyl glucosinolate may have anti–fatigue effects in young women. So, maca supplements containing benzyl glucosinolate represent a food and drug candidate for reducing fatigue. Keywords: maca, Lepidium meyenii, benzyl glucosinolate, daily fatigue, visual analogue scale
背景:日常疲劳对许多人来说是一个问题,因为它与其他疾病有关。玛咖最近作为一种恢复疲劳的食物引起了相当大的关注。玛咖富含苯硫代葡萄糖苷,通过防止糖原消耗来提高耐力。然而,其对疲劳的影响尚未在人体临床试验中进行研究。目的:本研究的主要目的是探讨玛咖补充剂对减轻疲劳的作用。方法:本研究评估了服用含有苄基硫代葡萄糖苷的玛咖提取物(9.6 mg/天)对成年女性疲劳的影响。这项随机、安慰剂对照、平行组双盲研究招募了60名受试者,他们被分配服用玛咖提取物或安慰剂4周。采用视觉模拟疲劳量表(visual analogue scale, VAS)对结果进行评价。血液变量和不良事件用于评估安全性。结果:两组患者4周后疲劳VAS评分均较进食前下降。在分层分析中,年龄小于45岁的受试者中,玛咖组VAS明显较低,且玛咖组补充前后的变化更大。结论:年轻女性服用含苄硫代葡萄糖苷的玛咖提取物可能具有抗疲劳作用。因此,含有苄基硫代葡萄糖苷的玛咖补充剂代表了一种减轻疲劳的食品和药物候选。关键词:玛咖,麦冬草,苄基硫代葡萄糖苷,日疲劳,视觉模拟量表

Background: Banana inflorescence is one of the edible parts of banana. It is well-known to have antioxidants and anti-diabetic potential health benefits. Methods: In this study, the banana inflorescence from Musa (ABB group) Namwa Mali-Ong was prepared using ethanol extraction and investigated for its biochemical compositions and biological activities. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) free radical scavenging, ferric reducing antioxidant power (FRAP), and 2,2’-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) free radical scavenging activity assays were performed. The phytochemical composition of the extract was analyzed using the ultra-high-performance liquid chromatography-electrospray ionization quadrupole time-of-flight mass spectrometry (UHLC-ESI-QTOF/MS) technique. Additionally, the ability of the extract to stimulate glucose in C2C12 myotube was investigated. Results: The ethanolic extract of banana inflorescence contained carbohydrate, protein, phenolic, and flavonoid compounds. The results show that the extract exhibited low-level antioxidant activities.  For example, the half-maximal inhibitory concentration (IC50) in the DPPH and ABTS assays was at 27.89 ± 0.054 and 21.33 ± 0.87 mg/mL, respectively. Although the extract possesses low-level antioxidant activities, it stimulated glucose uptake in C2C12 myotubes in a dose- and time-dependent fashion. Consistently, the UHLC-ESI-QTOF/MS analysis in both positive and negative electrospray ionization modes reveals several components in the extract such as phytosphingosine and α-linolenic acid that have previously been shown to exhibit an anti-diabetic activity.Conclusion: The results show that the inflorescence ethanolic extract possesses antioxidant and anti-diabetic activities and may potentially be developed into a health-promoting product such as an anti-diabetic drug. Keywords: antioxidant activity; banana inflorescence; glucose uptake; anti-diabetic; C2C12 myotubes
背景:香蕉花序是香蕉的可食用部分之一。众所周知,它具有抗氧化剂和抗糖尿病的潜在健康益处。方法:采用乙醇提取法制备了芭蕉Namwa Mali-Ong的花序,并对其生化成分和生物活性进行了研究。测定2,2-二苯基-1-吡啶肼基(DPPH)自由基清除能力、铁还原抗氧化能力(FRAP)和2,2 ' -氮唑(3-乙基苯并噻唑-6-磺酸)(ABTS)自由基清除能力。采用超高效液相色谱-电喷雾电离四极杆飞行时间质谱(UHLC-ESI-QTOF/MS)技术对提取物的植物化学成分进行分析。此外,我们还研究了提取物对C2C12肌管中葡萄糖的刺激能力。结果:香蕉花序乙醇提取物中含有碳水化合物、蛋白质、酚类化合物和黄酮类化合物。结果表明,该提取物具有较低的抗氧化活性。例如,DPPH和ABTS试验的半最大抑制浓度(IC50)分别为27.89±0.054和21.33±0.87 mg/mL。虽然提取物具有低水平的抗氧化活性,但它以剂量和时间依赖性的方式刺激C2C12肌管的葡萄糖摄取。与此一致的是,UHLC-ESI-QTOF/MS分析在正、负电喷雾电离模式下都揭示了提取物中的几种成分,如植物鞘苷和α-亚麻酸,这些成分先前已被证明具有抗糖尿病活性。结论:红花醇提物具有抗氧化和抗糖尿病活性,有开发成抗糖尿病药物等保健产品的潜力。关键词:抗氧化活性;香蕉的花序;葡萄糖吸收;抗糖尿病;C2C12肌管

Background: Almond skins are the byproduct of the almond industry that are rich in dietary fibers and polyphenols. Recently, there has been an increasing interest in utilizing the phenolic compounds from almond skins for their functional benefits. Galloylated catechins activate diacylglycerol kinase α (DGKα) which is involved in the amelioration of diabetic nephropathy. Therefore, in this study, we investigated whether almond skin polyphenol extracts can also induce the activation of DGKα.Methods: Phenolic contents in the almond skin polyphenol extracts were identified by liquid chromatography (LC)-time of flight mass spectrometry (TOFMS). Using confocal microscopy, the translocation of green fluorescent protein (GFP)-DGKα to the cell membrane was observed upon stimulation with almond skin polyphenol extracts. To check the involvement of 67 kDa laminin receptor (67LR), pre-treatment of anti-67LR antibody was used.Results: We identified that naringenin and flavanone (2,3-dihydroflavone), which are among the phenolic contents in the almond skin polyphenol extracts identified, can also induce the activation of DGKα. In addition, we also investigated whether the pathway involves the same receptor as that of epigallocatechin-3-gallate (EGCg); the 67LR. Naringenin stimulated through the 67LR, while flavanone mainly used the 67LR-independent pathways.Conclusion: These findings were additional function of almond skin polyphenol extracts and may implicate the benefits of the intake of nuts in daily diets. Polyphenols can be extracted from almond skins as an inexpensive source. The various health benefits of polyphenols can be applied to functional foods and supplements.Keywords: flavonoid, lipid kinase, imaging, catechin, vitamin E, diabetic nephropathy
背景:杏仁皮是杏仁工业的副产品,富含膳食纤维和多酚。最近,人们对利用杏仁皮中的酚类化合物的功能效益越来越感兴趣。没食子酸儿茶素激活二酰基甘油激酶α (DGKα),参与糖尿病肾病的改善。因此,本研究探讨了杏仁皮多酚提取物是否也能诱导DGKα的活化。方法:采用液相色谱(LC)-飞行时间质谱法(TOFMS)鉴定杏仁皮多酚提取物中酚类物质的含量。用共聚焦显微镜观察了绿色荧光蛋白(GFP)-DGKα在杏仁皮多酚提取物刺激下向细胞膜的易位。为了检测67kda层粘连蛋白受体(67LR)的参与情况,采用抗67LR抗体预处理。结果:我们鉴定出杏仁皮多酚提取物中的酚类成分柚皮素和黄酮(2,3-二氢黄酮)也能诱导DGKα活化。此外,我们还研究了该途径是否涉及与表没食子儿茶素-3-没食子酸酯(EGCg)相同的受体;67 lr。柚皮素通过67LR刺激,而黄酮主要通过67LR非依赖性途径刺激。结论:这些发现是杏仁皮多酚提取物的额外功能,可能暗示日常饮食中摄入坚果的益处。从杏仁皮中提取多酚是一种廉价的原料。多酚的各种健康益处可以应用于功能性食品和补充剂。关键词:类黄酮,脂激酶,成像,儿茶素,维生素E,糖尿病肾病
