BACKGROUND: Liver X receptor α (LXRα) and ATP-binding cassette transporter A1 (ABCA1) as a lipid transporter play an important role in cholesterol efflux from cells. OBJECTIVE: This study was aimed to determine the effect of kiwifruit supplementation on LXRα and ABCA1 gene expressions in liver and intestine of hamsters fed with high-fat diet (HFD). METHODS: 36 Golden Syrian male hamsters were divided into 6 groups (n = 6) including, group 1 received chow diet (control normal), group 2 and 3 received chow diet plus 1.86 and 3.73 g/kg kiwifruit, group 4 received HFD, group 5 and 6 received HFD plus 1.86 and 3.73 g/kg kiwifruit for 8 weeks. RESULTS: ABCA1 gene expression were significantly decreased in the liver (p <  0.01) and the intestine (p <  0.05) of HFD group compared with control normal. The gene expression levels of ABCA1 from liver and intestine were increased in HFD treated with kiwifruit compare to untreated HFD group (p <  0.05). LXRα gene expression of intestine was increased in all of the kiwifruit treated groups compared with untreated groups (p <  0.05). CONCLUSIONS: Consumption of kiwifruit in in hamsters receiving HFD can improve cholesterol efflux from liver and intestine by increase the gene expression of ABCA1 and LXRα.

BACKGROUND: Obesity, as a medical condition, results from interactions between environmental and genetic factors. The rs17782313 polymorphism, located 188kb downstream of the Melanocortin 4 Receptor (MC4R) gene, is one of the essential candidate genetic markers that has shown the highest association with obesity in different populations. OBJECTIVE: This study aimed to investigate the possible associations of rs17782313 polymorphism near the MC4R gene with obesity/overweight, body mass index (BMI), and hedonic hunger among women from the Iranian Azeri ethnic group. METHODS: Five hundred sixty-three women, composed of 396 patients with obesity/overweight and 167 unrelated healthy controls, were genotyped for the rs17782313 polymorphism by applying the polymerase chain reaction-restriction fragment length polymorphism (PCR–RFLP) method. RESULTS: This population was in Hardy-Weinberg equilibrium (P = 0.878). The study confirmed a significant association of rs17782313 with obesity, where subjects carrying the C/C genotype had higher odds of obesity (OR = 2.681, P = 0.005, 95%CI:1.340–5.365). Also, C allele carriers have statistically significantly higher BMI scores than those carrying the T allele (P = 0.029). However, no significant associations were found among PFS scores and genotypic/allelic groups of rs17782313 polymorphism (P = 0.368). CONCLUSIONS: Our findings suggest that rs17782313 polymorphism is strongly associated with obesity and BMI but not with hedonic hunger among Northwest Iran women. Moreover, the sequencing data analysis in several homozygous and heterozygous carriers of the C allele led to identifying a novel frameshift variant with TCT deletion (rs534212081) in the 166 upstream of rs17782313, which has not been reported so far.
背景:肥胖作为一种医学状况,是环境和遗传因素相互作用的结果。rs17782313多态性位于黑色素皮质素4受体(MC4R)基因下游188kb,是不同人群中与肥胖相关性最高的重要候选遗传标记之一。目的:本研究旨在探讨伊朗-阿塞拜疆族女性MC4R基因附近rs17782313多态性与肥胖/超重、体重指数(BMI)和享乐饥饿的可能关联。方法:采用聚合酶链式反应-限制性片段长度多态性(PCR-RFLP)方法对563名女性(包括396名肥胖/超重患者和167名无关健康对照)的rs17782313多态性进行基因分型。结果:该群体处于Hardy-Weinberg平衡状态(P = 0.878)。该研究证实rs17782313与肥胖显著相关,其中携带C/C基因型的受试者肥胖的几率更高(OR = 2.681,P = 0.005,95%CI:1.340-5.365)。此外,C等位基因携带者的BMI评分在统计学上显著高于携带T等位基因的人(P = 而rs17782313多态性在PFS评分和基因型/等位基因组之间无显著相关性(P = 0.368)。结论:我们的研究结果表明,rs17782313多态性与伊朗西北部女性的肥胖和BMI密切相关,但与享乐饥饿无关。此外,对C等位基因的几个纯合和杂合携带者的测序数据分析导致在rs17782313上游166处鉴定出一种新的TCT缺失的移码变体(rs534212081),该变体迄今尚未报道。

COVID-19, first reported in Wuhan, China in December 2019 quickly spread worldwide leading to serious health, social and economic consequences. A crucial role in the pathogenesis of severe disease has been attributed to the inflammatory status, that in more severe cases may evolve in an overproduction of pro-inflammatory cytokines (“cytokine storm)” and fatal outcome. Non-communicable diseases, nutritional disorders and advanced age, conditions associated with a low-grade systemic inflammation and immune function alterations, have been identified as major risks for severe COVID-19. General recommendations for fighting COVID-19 highlighted the paramount importance of adopting a healthy plant-based dietary pattern and healthy lifestyle. The Mediterranean dietary pattern is considered as one of the healthiest dietary patterns, and its benefits are supported by a large body of evidence. Furthermore, it is considered as a sustainable lifestyle model. The aim of this research was to update the multiple benefits of the Mediterranean dietary pattern on physical and mental health, focusing on the effects that it may have in combating COVID-19. The potential effects and mechanisms of action of the main bioactive components of Mediterranean diet were also analyzed. Considering its effects in modulating inflammation and oxidative stress and supporting the immune system, the Mediterranean dietary pattern may be considered the most promising dietary approach to combat COVID-19.
2019年12月在中国武汉首次报告的新冠肺炎在全球迅速传播,导致严重的健康、社会和经济后果。炎症状态在严重疾病的发病机制中起着至关重要的作用,在更严重的情况下,炎症状态可能会演变为促炎细胞因子的过度产生(“细胞因子风暴”)和致命结果。非传染性疾病、营养障碍和高龄、与低级别全身炎症和免疫功能改变相关的疾病已被确定为严重新冠肺炎的主要风险。抗击新冠肺炎的一般建议强调了采用健康的植物性饮食模式和健康生活方式的极端重要性。地中海饮食模式被认为是最健康的饮食模式之一,其益处得到了大量证据的支持。此外,它被认为是一种可持续的生活方式模式。这项研究的目的是更新地中海饮食模式对身心健康的多重益处,重点关注其在抗击新冠肺炎方面可能产生的影响。还分析了地中海饮食中主要生物活性成分的潜在作用和作用机制。考虑到其在调节炎症和氧化应激以及支持免疫系统方面的作用,地中海饮食模式可能被认为是对抗新冠肺炎最有前途的饮食方法。

Synbiotic supplementation can improve metabolic disorders. The aim of this study was to assess the impact of synbiotic supplementation on the levels of asprosin, lipid profile, glucose, and insulin resistance in pregnant rats fed a high-fat diet (HFD). Rats were divided into three groups: control group (fed base chow), HFD group, and HFD + synbiotic group. Levels of blood glucose, total cholesterol, triglyceride (TG), low-density lipoprotein (LDL), high-density lipoprotein (HDL), insulin, and asprosin levels were measured. Birth weight of offspring in the HFD + synbiotic group was significantly lower than in the HFD group. Similarly, serum asprosin, insulin, insulin resistance, TG and total cholesterol levels in the HFD + symbiotic group were significantly lower than in the HFD group. Asprosin levels had a significant and positive correlation between food intake in the first ten days of the experiment and gestation period, fasting blood sugar (FBS), TG, and homeostatic model assessment (HOMA) index. Moreover, asprosin levels had a significant and negative correlation with HDL and insulin levels. Results showed, synbiotic supplementation has beneficial effects on obese animals and improves weight gain during pregnancy, pup birth weight, FBS, insulin resistance and lipid profile. These advantages of synbiotic supplementation could be mediated by reducing serum asprosin levels.
补充合成菌可以改善代谢紊乱。本研究的目的是评估合成补充剂对喂食高脂肪饮食(HFD)的怀孕大鼠的asprosin水平、脂质谱、葡萄糖和胰岛素抵抗的影响。将大鼠分为3组:对照组(基础饲料)、HFD组和HFD +合成组。测量血糖、总胆固醇、甘油三酯(TG)、低密度脂蛋白(LDL)、高密度脂蛋白(HDL)、胰岛素和阿斯丁蛋白水平。HFD +合成组子代出生体重显著低于HFD组。同样,HFD +共生组血清asprosin、胰岛素、胰岛素抵抗、TG和总胆固醇水平均显著低于HFD组。Asprosin水平与试验前10 d摄食量、妊娠期、空腹血糖(FBS)、TG、稳态模型评估(HOMA)指数呈显著正相关。此外,asprosin水平与HDL和胰岛素水平呈显著负相关。结果表明,饲粮中添加益生菌对肥胖动物具有有益作用,可改善妊娠期增重、幼畜出生体重、FBS、胰岛素抵抗和血脂。这些优势可能是通过降低血清阿斯丁蛋白酶水平介导的。

BACKGROUND: The food frequency questionnaire (FFQ) is the method of choice for dietary assessment in epidemiological studies. FFQs focusing on mixed-dishes and simple food items are useful where mixed-dishes are an essential part of food consumption. OBJECTIVE: Regarding the fact that the nature of the Iranian diet is mixed-dish, the present study aimed to design and assess the validity and reproducibility of a dish-based semi-quantitative FFQ in the Iranian adult population. METHODS: A list of 302 food items was collected from four geographical areas around Iran. The validation study was conducted on 97 healthy adults. The FFQ was introduced at the beginning of the study and 10 months after; two three-day food records were collected during the study. Also, biomarkers including 24-hour urinary potassium and nitrogen, serum retinol, and alpha-tocopherol were measured. RESULTS: A 142-food-item FFQ was concluded. The correlation coefficient between the second FFQ and the second three-day food record ranged from 0.225 to 0.323 for macronutrients and 0.128 to 0.476 for micronutrients. The percentile agreements (same or adjacent quartile) between the two methods were more than 60%for all nutrients. The intraclass correlation coefficient between FFQs (except for vitamin E) ranged from 0.363 to 0.578. The correlation coefficient between the second FFQ and the second biomarker assessment was 0.241 for protein.
背景:食物频率问卷(FFQ)是流行病学研究中膳食评估的首选方法。当混合菜肴是食物消费的重要组成部分时,关注混合菜肴和简单食品的FFQs是有用的。目的:考虑到伊朗饮食的本质是混合菜肴,本研究旨在设计和评估伊朗成年人群中基于菜肴的半定量FFQ的有效性和可重复性。方法:从伊朗四个地理区域收集302种食品。验证性研究在97名健康成人中进行。FFQ在研究开始时和10个月后引入;研究期间收集了两次为期三天的饮食记录。同时,测量24小时尿钾和尿氮、血清视黄醇和α -生育酚等生物标志物。结果:得出了142个食品项目的FFQ。第二次FFQ与第二次三天摄食记录的相关系数分别为:宏量营养素0.225 ~ 0.323、微量营养素0.128 ~ 0.476。对于所有营养素,两种方法之间的百分位数一致性(相同或相邻四分位数)超过60%。除维生素E外,各ffq的类内相关系数为0.363 ~ 0.578。蛋白质的第二次FFQ与第二次生物标志物评估的相关系数为0.241。

OBJECTIVE: This study evaluated the effect of sardine (SPH) and chickpea protein hydrolysates (CPH) on oxidant stress and inflammatory profile in cholesterol-fed rats. METHODS: The experiment was undertaken for thirty days on 18 cholesterol-fed Wistar rats (220±10 g) divided into three groups and receiving 1 g/kg of body weight either chickpea protein hydrolysate (CPH), sardine protein hydrolysate (SPH) or casein in water (CG). RESULTS: Compared to CG, SPH and CPH treatment reduced cholesterol, hydroperoxide and malondialdehyde contents in serum, lipoproteins, erythrocytes and aorta. These same treated groups showed also lower serum isoprostane levels. However, serum paraoxonase activity and HDL-antioxidant property were improved only by CPH compared to CG. SOD activity of aorta and erythrocytes was higher in CPH but in SPH group, SOD activity was lower in these tissues and remained unchanged in serum. Furthermore, CPH and SPH stimulated glutathione peroxidase and catalase activities of aorta and erythrocytes. In CPH group, nitric oxide levels of serum, erythrocytes and aorta were increased by respectively 1.4- to 1.8-fold compared to CG and SPH. In addition, among the three groups, CPH exhibited the best anti-inflammatory effect by lowering serum C reactive protein, uric acid and albumin concentrations. CONCLUSIONS: SPH and particularly CPH possess antioxidant and anti-inflammatory properties and could be useful as nutraceuticals for health improving and preventing numerous disorders such as cardiovascular diseases.
目的:本研究评估沙丁鱼(SPH)和鹰嘴豆蛋白水解物(CPH)对胆固醇喂养大鼠氧化应激和炎症的影响。方法:采用胆固醇喂养的Wistar大鼠18只(220±10 g),随机分为3组,分别饲喂1 g/kg体重鹰嘴豆蛋白水解物(CPH)、沙丁鱼蛋白水解物(SPH)和水中酪蛋白(CG),为期30 d。结果:与CG相比,SPH和CPH降低了血清、脂蛋白、红细胞和主动脉中胆固醇、过氧化氢和丙二醛的含量。这些治疗组也显示出较低的血清异前列腺素水平。然而,与CG相比,CPH仅提高了血清对氧磷酶活性和hdl抗氧化性能。CPH组主动脉和红细胞SOD活性升高,但SPH组SOD活性降低,血清中SOD活性不变。此外,CPH和SPH刺激主动脉和红细胞谷胱甘肽过氧化物酶和过氧化氢酶活性。CPH组血清、红细胞和主动脉一氧化氮水平较CG和SPH组分别升高1.4 ~ 1.8倍。此外,CPH通过降低血清C反应蛋白、尿酸和白蛋白浓度,在三组中表现出最好的抗炎作用。结论:SPH,特别是CPH具有抗氧化和抗炎作用,可作为保健品用于改善健康和预防心血管疾病等多种疾病。

BACKGROUND: Aging is a process that does not refer only to the accumulation of damage in a human being over time but rather to individual changes determined by genetic, lifestyle, social and environmental factors. Aging is one of the greatest known risk factors for most human diseases. An older person in good health has a good level of independence, weighs less on the national health system and plays a productive and active role in his/her community; thus, the concept of “healthy aging”, reflecting older adult-environment fit should be promoted. The interactions between lifestyle, including nutrition, and health play a fundamental role in the aging process; eating habits and eating behaviours are recognized as important modifiable factors potentially leading to a healthy “phenotype”. OBJECTIVE AND METHODS: A multidisciplinary consortium with three Italian universities (the University of Milano-Bicocca, University of Pavia and University of Calabria) and Italian Small-Medium Enterprises proposed the Food Social Network (Food NET) project. Food NET overall outcome is to achieve target-specific guidelines and exact technologies for accessible functional foods, aimed at improving the quality of life and nutritional status of citizens (aged>65) of the Metropolitan City of Milan (Italy). CONCLUSIONS: This project is part of the “Smart Living” and food-related strategies aimed at responding to the needs of this target population, developing new food products, appropriate to meet the specific requirements and ensuring and promoting sustainable diets for healthy aging by effective food policy approaches.
背景:衰老是一个过程,不仅是指人体损伤随着时间的积累,而是指由遗传、生活方式、社会和环境因素决定的个体变化。衰老是大多数人类疾病已知的最大危险因素之一。健康状况良好的老年人具有良好的独立性,对国家卫生系统的影响较小,并在其社区中发挥富有成效和积极的作用;因此,应提倡体现老年人与环境契合度的“健康老龄化”理念。生活方式(包括营养)与健康之间的相互作用在衰老过程中起着重要作用;饮食习惯和饮食行为被认为是重要的可改变因素,可能导致健康的“表型”。目的与方法:由意大利三所大学(米兰-比可卡大学、帕维亚大学和卡拉布里亚大学)和意大利中小企业组成的多学科联盟提出了食品社会网络(Food NET)项目。Food NET的总体成果是实现可获得功能性食品的特定目标指南和精确技术,旨在改善意大利米兰大都会(65岁至65岁)公民的生活质量和营养状况。结论:该项目是“智慧生活”和食品相关战略的一部分,旨在响应目标人群的需求,开发适合特定要求的新食品,并通过有效的食品政策方法确保和促进可持续饮食,以促进健康老龄化。

BACKGROUND: Doxorubicin (DOX) is one of most used chemotherapeutic drugs, but it has important adverse effects. Nutrition has a critical role to prevent or minimize chemotherapy side effects. Caloric and nutrient restriction has been widely studied in different health fields showing extensive beneficial effects. Given the importance of these interventions, it is expected that some of them have benefits in patients under DOX chemotherap OBJECTIVE: This review aimed to compile published studies evaluating the effects of different dietary intetrventions based on restriction of calories or certain nutrients against DOX-induced damage and toxicity. RESULTS: Caloric restriction and partial reduction of fat have shown to reduce DOX cardiotoxicity correlating with a reduction of oxidative stress. Reduction of dietary fat was proved to act in the same sense at liver and kidney. Studies in relation to protein reduction is more elevated has focused only on kidneys and bone, and under certain circumstances, these interventions could increase susceptibility to DOX toxicity. CONCLUSIONS: The promising effects of restriction of dietary fat, protein and sodium on differerent organs have been supported by a greater number of studies among all the dietary interventions evaluated. Still, clinical studies are necessary to confirm the potential usefulness of these interventions.
背景:阿霉素(DOX)是最常用的化疗药物之一,但也有重要的不良反应。营养在预防或减少化疗副作用方面起着至关重要的作用。热量和营养限制在不同的健康领域得到了广泛的研究,显示出广泛的有益效果。考虑到这些干预措施的重要性,预计其中一些干预措施对DOX化疗患者有益。目的:本综述旨在汇编已发表的研究,评估基于限制卡路里或某些营养素的不同饮食干预措施对DOX诱导的损伤和毒性的影响。结果:热量限制和脂肪的部分减少显示出与氧化应激减少相关的DOX心脏毒性。研究证明,减少膳食脂肪对肝脏和肾脏也有同样的作用。与蛋白质减少率升高有关的研究只关注肾脏和骨骼,在某些情况下,这些干预措施可能会增加对DOX毒性的易感性。结论:在所有被评估的饮食干预措施中,大量研究支持限制饮食中脂肪、蛋白质和钠对不同器官的有希望的影响。尽管如此,仍有必要进行临床研究来证实这些干预措施的潜在有效性。

BACKGROUND: Nowadays, medicinal plants have attracted great interest in treatment of human diseases. Rosemary is a well-known medicinal plant which has been widely used for different therapeutic purposes. METHODS: This is a narrative review using databases including PubMed, ISI, Scopus, ScienceDirect, Cochrane, and google scholar, the most authoritative articles were searched, screened, and analyzed. RESULTS: Rosemary is a natural antioxidant which removes reactive oxygen species from tissues and increases expression on Nrf2 gene. Rosemary and its metabolites reduce inflammation by inhibiting production of pro-inflammatory cytokines, decreasing expression of NF-κB, inhibiting infiltration of immune cells to inflamed sites, and affecting gut microbiome. Besides, rosmarinic acid in rosemary extract has positive effects on renin-angiotensin-system. Rosemary affects respiratory system by reducing oxidative stress, inflammation, muscle spasm, and also through anti-fibrotic properties. Carnosic acid is able to penetrate blood-brain-barrier and act against free radicals, ischemia and neurodegeneration in brain. Cardioprotective effects include correcting lipid profile, controlling blood pressure by inhibition of ACE, prevention of atherosclerosis, and reduction of cardiac muscle hypertrophy. CONCLUSIONS: Accordingly, rosemary supplementation has potential protective effects against COVID-19 and other cytokine storm associated infections, a conclusion that needs more evaluations in the next clinical trials.
背景:药用植物在治疗人类疾病方面引起了人们极大的兴趣。迷迭香是一种著名的药用植物,被广泛用于不同的治疗目的。方法:使用PubMed、ISI、Scopus、ScienceDirect、Cochrane和谷歌scholar等数据库,对最权威的文章进行检索、筛选和分析。结果:迷迭香是一种天然抗氧化剂,能清除组织中的活性氧,增加Nrf2基因的表达。迷迭香及其代谢物通过抑制促炎细胞因子的产生、降低NF-κB的表达、抑制免疫细胞向炎症部位的浸润、影响肠道微生物群来减轻炎症。此外,迷迭香提取物中的迷迭香酸对肾素-血管紧张素系统有积极作用。迷迭香通过减少氧化应激、炎症、肌肉痉挛和抗纤维化特性影响呼吸系统。鼠尾草酸具有穿透血脑屏障、抗自由基、抗脑缺血、抗脑神经变性等作用。心脏保护作用包括纠正血脂,通过抑制ACE控制血压,预防动脉粥样硬化,减少心肌肥厚。结论:因此,迷迭香补充剂对COVID-19和其他细胞因子风暴相关感染具有潜在的保护作用,这一结论需要在下一步的临床试验中进行更多的评估。

BACKGROUND: The major component of lemongrass by weight is dietary fibre (DF), but no literature has been reported on its DF components and fermentation products when ingested. OBJECTIVE: This study analysed DF components of lemongrass, investigated the potential of the major product from total DF (TDF) fermentation to inhibit α-amylase and HMG-CoA reductase, key enzymes of diabetes mellitus and hypercholesterolemia, respectively, and determined the serum glucose- and cholesterol-lowering potential of TDF in an animal model. METHODS: Lemongrass DF components were analysed, TDF was fermented in vitro; the major fermentation product was isolated for enzyme inhibitory assays; and postprandial blood glucose- and cholesterol-lowering potential of TDF was determined in Sprague-Dawley rats. RESULTS: TDF in lemongrass was 65.7 g/100g and soluble DF, 2.8 g/100 g. Significant amount of propionate (10.9 mM/g TDF) was produced after TDF fermentation; propionate inhibited 20.4% α-amylase activity, and 13.1 % HMG-CoA reductase activity in vitro. TDF further exhibited antihyperglycemic and cholesterol-lowering potential in an animal model. CONCLUSIONS: DF from lemongrass was shown to reduce hyperglycemia and hypercholesterolemia in an animal model, through mild inhibition of α-amylase and HMG-CoA reductase. Thus, lemongrass DF may have a significant role in mitigating the risk of type 2 diabetes mellitus and hypercholesterolemia.
背景:按重量计算,柠檬草的主要成分是膳食纤维(DF),但尚未有文献报道其膳食纤维成分和食用后的发酵产物。目的:分析柠檬草的DF成分,研究总DF (total DF, TDF)发酵主要产物对糖尿病和高胆固醇血症关键酶α-淀粉酶和HMG-CoA还原酶的抑制作用,并在动物模型中测定总DF的降血糖和降胆固醇作用。方法:分析柠檬草DF成分,体外发酵TDF;分离主要发酵产物进行酶抑制试验;测定了TDF在Sprague-Dawley大鼠餐后降血糖和降胆固醇的潜力。结果:香茅中TDF含量为65.7 g/100g,可溶性DF含量为2.8 g/100g。发酵后的丙酸含量显著(10.9 mM/g TDF);丙酸对α-淀粉酶活性抑制20.4%,对HMG-CoA还原酶活性抑制13.1%。在动物模型中,TDF进一步表现出抗高血糖和降胆固醇的潜力。结论:在动物模型中,柠檬草DF通过轻度抑制α-淀粉酶和HMG-CoA还原酶,显示出降低高血糖和高胆固醇血症的作用。因此,柠檬草DF可能在降低2型糖尿病和高胆固醇血症的风险方面具有重要作用。
