The influence of the lipid complex isolated from the thallus of the red marine algaeAhnfeltia tobuchiensis(LCA) on the metabolic parameters of the blood and liver of rats under a high-fat diet was studied. It was shown that the administration of LCA had a pronounced lipid-correcting and antioxidant effect, which was superior to that of the reference preparation "Omega 3-6-9" in terms of its ability to restore lipid metabolism, the ratio of lipoprotein fractions and the indices of the endogenous antioxidant protection system, as so as prevent the development of hepatosis. The lipid-correcting and anti-oxidant effect of LCA is specified by the action of n-3 polyunsaturated fatty acids, in particular eicosapentaenoic acid, which are the part of the structure of phospholipids and glycolipids of marine origin, which make up the main part of the studied lipid complex.

Supplementation of polysaccharides is a promising gut microbiota-targeted therapeutic method for obesity and metabolic diseases. Biological activities of Cordyceps militaris polysaccharides have been well reported, but the effect of selenium (Se)-rich C. militaris polysaccharides (SeCMP) on obesity and associated metabolic disorder and gut microbiota composition has been rarely studied. This study aimed to investigate the anti-obesity and gut microbiota modulatory effect of crude polysaccharides separated from Se-rich C. militaris on a high-fat diet (HFD)-fed C57BL/6J mice model. Mice were treated with a normal diet (CHOW), HFD alone, HFD plus C. militaris polysaccharides (CMP), or low/medium/high dosage of SeCMP for 8 weeks. Body weight, fat content, serum lipid, appetite hormone, lipid gene expression, inflammation cytokines, thermogenic protein, short-chain fatty acids (SCFAs), and gut microbiota structure of the mice were determined. Compared with HFD-fed mice, the serum triglyceride and low-density lipoprotein cholesterol (LDL-C) in the SeCMP-200 group were decreased by 51.5% and 44.1%, respectively. Furthermore, serum lipopolysaccharide-binding proteins (LBP), adiponectin level, and pro-inflammation gene expression in the colon and subcutaneous fat were inhibited, whereas anti-inflammation gene expression was improved, reflecting SeCMP-200 might mitigate obese-induced inflammation. Meanwhile, SeCMP-200 promoted satiety and thermogenesis of obese mice. It also significantly decreased gut bacteria, such as Dorea, Lactobacillus, Clostridium, Ruminococcus, that negatively correlated with obesity traits and increased mucosal beneficial bacteria Akkermansia. There was no significant difference between CMP and SeCMP-100 groups. Our results revealed a high dose of SeCMP could prevent HFD-induced dyslipidemia and gut microbiota dysbiosis and was potential to be used as functional foods.

Maqui (Aristotelia Chilensis) berry features a unique profile of anthocyanidins that includes high amounts of delphinidin-3-O-sambubioside-5-O-glucoside and delphinidin-3-O-sambubioside and has shown positive effects on fasting glucose and insulin levels in humans and murine models of type 2 diabetes and obesity. The molecular mechanisms underlying the impact of maqui on the onset and development of the obese phenotype and insulin resistance was investigated in high fat diet-induced obese mice supplemented with a lyophilized maqui berry. Maqui-dietary supplemented animals showed better insulin response and decreased weight gain but also a differential expression of genes involved in de novo lipogenesis, fatty acid oxidation, multilocular lipid droplet formation and thermogenesis in subcutaneous white adipose tissue (scWAT). These changes correlated with an increased expression of the carbohydrate response element binding protein b (Chrebpb), the sterol regulatory binding protein 1c (Srebp1c) and Cellular repressor of adenovirus early region 1A–stimulated genes 1 (Creg1) and an improvement in the fibroblast growth factor 21 (FGF21) signaling. Our evidence suggests that maqui dietary supplementation activates the induction of fuel storage and thermogenesis characteristic of a brown-like phenotype in scWAT and counteracts the unhealthy metabolic impact of an HFD. This induction constitutes a putative strategy to prevent/treat diet-induced obesity and its associated comorbidities. ; This study was supported by the Ministerio de Economía y Competitividad (grants AGL2017-82417-R to PFM and DH and AGL2016-75329-R to RML-R), by the Generalitat (grants 2017SGR683 and 2017SGR196), by the Associació Catalana de la Diabetis to JR (grant 600004—Ajut ACD a la recerca en diabetis 2017), Instituto de Salud Carlos III, ISCIII from the Ministerio de Ciencia, Innovación y Universidades (CIBEROBN—AEI/FEDER, UE).

The proposal of this study was to evaluate the role of diets rich in saturated fat and cholesterol in some aspects of periodontal diseases in a lipopolysaccharide (LPS)-induced model of periodontal disease in rabbits and to assess the influence of a periodontal intervention on hyperlipidemia, atherosclerosis, and NAFLD progression to non-alcoholic steatohepatitis. Male rabbits were maintained on a commercial standard diet or a diet rich in saturated fat (3% lard w/w) and cholesterol (1.3% w/w) (HFD) for 40 days. Half of the rabbits on each diet were treated 2 days per week with intragingival injections of LPS from Porphyromonas gingivalis. Morphometric analyses revealed that LPS induced higher alveolar bone loss (ABL) around the first premolar in animals receiving standard diets, which was exacerbated by the HFD diet. A higher score of acinar inflammation in the liver and higher blood levels of triglycerides and phospholipids were found in HFD-fed rabbits receiving LPS. These results suggest that certain dietary habits can exacerbate some aspects of periodontitis and that bad periodontal health can contribute to dyslipidemia and promote NAFLD progression, but only under certain conditions. ; Ministry of Education, Culture and Sport (Spain) ; Spanish Government ; Traslados Temporales FPU (University of Kings College of London)

The article suggests the definition of political humor as based on the stereotypes optimization tool of communication about the political situation in the country and key figures on its political arena. The participants of this communication can be political subjects and their audience and also citizens themselves. Based on the content analysis of the KVN (Club of cheerful and resourceful) games was made a conclusion about the censoring political humor according to the aims of government propaganda; it was revealed that in the political humor of the KVN they actively use the manipulative methods; it was proved that political humor which made V. V. Putin a hero and discredits those disliked by the government political figures and ideas of other countries in the mass consciousness. As a result it provides the support of the internal policy of Russia by the population and at the same time it fixes prejudiced attitude to everything «foreign» in the society. ; В статье предлагается определение политического юмора как основанного на стереотипах средства оптимизации коммуникации между политическими субъектами и их аудиторией, а также между гражданами государства на предмет обсуждения политической ситуации в стране и ключевых фигур на ее политической арене. На основе контент-анализа игр КВН сделан вывод о цензурировании политического юмора в соответствии с целями государственной пропаганды; выявлено, что в политическом юморе КВН активно используются приемы манипуляции; доказан факт героизации В. В. Путина и дискредитации в массовом сознании неугодных для власти деятелей и идей других государств, что обеспечивает поддержку населением внутренней политики России и одновременно закрепляет в обществе предвзятое отношение ко всему западному.
