{"title":"Effect of pulse consumption on obesity and the metagenome","authors":"H. Thompson, T. Weir, J. McGinley, E. Neil","doi":"10.3390/iecn2020-07009","DOIUrl":"https://doi.org/10.3390/iecn2020-07009","url":null,"abstract":"Grain legumes, which are commonly referred to as pulses, are staple foods in many parts of the world, but are infrequently consumed in most economically developed countries where the obesity pandemic is prominent. However, even in low pulse consuming countries such as the United States, there are sub-groups of individuals who consume large amounts of pulses. Systematic reviews of population studies indicate that pulse consumers have a lower risk for developing obesity. To determine whether these population-based findings could be modeled in preclinical systems in which such findings can be deconstructed, we used rat and mouse models of dietary induced obesity and reported that lipid accumulation was inhibited. In this study, we examined the relationship between inhibition of fat accumulation and changes in the gut associated microbiome in male C57BL/6 mice fed either a high fat diet with casein as the protein source or that diet formulation in which one of four pulses (chickpea, common bean, dry pea, or lentil) was substituted to provide 70% dietary protein with the remainder provided by casein. The seeds of each pulse were soaked, cooked, and then freeze-dried and milled; the resulting powder was used for diet formulation. Mice were ad libitum fed over the 17-week duration of the feeding trial. Cecal content was obtained at necropsy and immediately snap frozen in liquid nitrogen. Extracted genomic DNA was processed for 16s rRNA sequencing on an Illumina system. Significant differences were observed between each pulse and the high fat control diet in microbial phylogenetic diversity (p < 0.001) and accumulation of lipid in adipose depots (p < 0.01). Differences among pulses were also observed in both metrics. Microbiome alpha and beta diversity metrics, differences in abundance for each detected taxon among treatment groups, and their relationships to changes in lipid accumulation in adipose storage depots are reported.","PeriodicalId":320592,"journal":{"name":"Proceedings of The 1st International Electronic Conference on Nutrients - Nutritional and Microbiota Effects on Chronic Disease","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129977001","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Elateriospermum tapos has the potential as an antioxidant and inhibitor of lipids (pancreatic lipase) and carbohydrates ( α -amylase and α -glucosidase) which are beneficial to combat obesity and diabetes. This study aimed to investigate the effect of E. tapos supplementation in obese rats prior to pregnancy on the dam and male offspring body weight and the level of stress hormones—adrenocorticotropic hormone (ACTH) and corticosterone (CORT). Thirty female Sprague Dawley rats were used in this study. Six rats were assigned to a normal diet (DND) group fed with a standard chow diet. The remaining rats were fed with a high-fat and cafeteria diet (HFCD) to generate obesity for five weeks. The obese rats were further divided into four groups (n = 6/group); dams negative control group (DNC, normal saline), dams positive control group (DPC, 200 mg/kg body weight of orlistat), dams treatment 1 group (DTX1, 200 mg/kg BW of E. tapos seed) and dams treatment 2 group (DTX2, 200 mg/kg BW of E. tapos shell). The treatment was given for six weeks daily before mating. At weaning, male offspring were designated into six groups according to their dam’s group (n = 6/group) and continued with the cafeteria diet except for the control group. The offspring were culled at 12 weeks of age for blood sample collections. DTX2 and their male adult offspring showed significantly lower body weight compared to DNC and their male offspring. Male offspring from DTX2 also showed significantly low ACTH and CORT levels compared to male offspring from the DNC group and a comparable level with the DND group. E. tapos shell supplementation was effective in reducing the development of obesity and suppressed stress through the regulation of ACTH","PeriodicalId":320592,"journal":{"name":"Proceedings of The 1st International Electronic Conference on Nutrients - Nutritional and Microbiota Effects on Chronic Disease","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128264552","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Breast cancer (BC) has the highest incidence and mortality in women worldwide and national; subtype triple negative (TN) is the most aggressive type because it is not susceptible to conventional therapy. Since 2004, the World Health Organization (WHO) approved use of alternative treatments as adjuvants based on evidence of its benefits. Since then, different natural alternatives to treat cancer have been studied, including Origanum vulgare ( Ov ) and carvacrol (Crv), one of its main compounds. However, cytotoxic potential of these products has not been studied in this subtype of BC. The objective of this study was to evaluate the cytotoxic effect of Ov and Crv on TN BC cell line (HCC-70). Lethal dose 50 was determined on control cell line HaCaT through 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assays with Ov and Crv stimulus in different doses and concentrations; the found dose was used on the HCC-70 cell line. The results were evaluated by ANOVA, finding that Ov reduced the proliferation by 94.05% ± 0.11 ( p < 0.001) and Crv by 93.43% ± 0.21 ( p < 0.001) compared to untreated cells. This suggests that both Ov and Crv present a powerful cytotoxic effect against the HCC-70 cell line and are promising options that should receive further study.","PeriodicalId":320592,"journal":{"name":"Proceedings of The 1st International Electronic Conference on Nutrients - Nutritional and Microbiota Effects on Chronic Disease","volume":"262 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121426354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pilla","doi":"10.3390/iecn2020-06982","DOIUrl":"https://doi.org/10.3390/iecn2020-06982","url":null,"abstract":": Metabolic-based therapies such as nutritional ketosis have been proven effective for seizure disorders and various acute and chronic neurological pathologies. In a healthy brain, glucose is the primary metabolic fuel for cells. However, neurodegenerative disorders, such as Alzheimer’s disease (AD), Parkinson’s disease (PD), seizure disorders, and traumatic brain injury (TBI) are associated with impaired glucose transport and metabolism and with mitochondrial dysfunction leading to energy deficit. Therapeutic ketosis can be considered as a form of metabolic therapy by providing alternative energy substrates. In addition, ketosis leads to metabolic adaptations that improve brain metabolism, restore mitochondrial ATP production, decrease reactive oxygen species production, reduce inflammation, and increase the activity of neurotrophic factors. Moreover, the synaptic activity between neurons is also stabilized through the increase of Szent-Györgyi–Krebs cycle intermediates, antioxidant effects, increased GABA-to-glutamate ratio, and activation of ATP-sensitive potassium channels.","PeriodicalId":320592,"journal":{"name":"Proceedings of The 1st International Electronic Conference on Nutrients - Nutritional and Microbiota Effects on Chronic Disease","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126975606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cocoa intake might help in protecting against oxidative damage and impaired immune functioning. The aim of this study was to establish the effect of cocoa and cocoa fibre on the oxidative status and the immunoglobulin (Ig) production of rats following a bout of acute exercise on a treadmill. The production of reactive oxygen species (ROS) by macrophages and the concentration of serum and mucosal Ig was assessed 16 h after the running session. Exercise increased ROS production and decreased the serum IgG concentration and the salivary gland IgM content. A cocoa fibre-enriched diet prevented the increased ROS production and the reduction in salivary IgM induced by exercise, although it decreased the IgA content in serum and the salivary glands. Overall, cocoa, by means of its fibre content, can partially prevent the alterations in ROS and Ig production induced by a single session of intensive running exercise.","PeriodicalId":320592,"journal":{"name":"Proceedings of The 1st International Electronic Conference on Nutrients - Nutritional and Microbiota Effects on Chronic Disease","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115236020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
