The extraction was carried out with water or ethanol at room temperature or by heating as well as following exposure to ultrasound. The extracts of the four seasons obtained with the four extraction methods were compared for their contents in carbon, nitrogen (N), sulfur (S), potassium (K), betulin, betulinic acid, potassium, flavonoids, and polyphenols. The antiradical effect as well as the photoprotective effects of all extracts were also investigated. The results show that there is no difference between the quantities extracted from the extracts of the 4 seasons. The results show a significant difference between the mass of the extracts obtained with water and ethanol. Betulinic acid was found to be more abundant in the extracts obtained with water while betulin was more abundant in the extracts obtained with ethanol. The mushroom and the extracts had high C contents, but low N and S contents, typical of protein-poor and carbohydrate-rich materials. Extracts were particularly rich in potassium, five times more than bananas. Heating favors the extraction of polyphenols and flavonoids. The aqueous extracts of chaga harvested in winter had the highest antiradical capacity. With a Sun Protection Factor (SPF) higher than 30 in the UVB wavelength, chaga extracts might be used as sunscreen. Extracts obtained with water had the highest SPF in general. The analysis of this mushroom further highlights this local product that deserves more attention for its potential benefits as a functional food/nutraceutical product. In addition to its nutritional values, this mushroom can also be used for its cosmetic qualities as it can be used as a sunscreen.","PeriodicalId":93800,"journal":{"name":"Nutraceuticals","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43136414","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}

The phenolic antioxidant 3,5-dihydroxy-4-methoxybenzyl alcohol (DHMBA) prevents oxidative stress as radical scavenging in cells. However, the role of the disorder as a pharmacologic factor has been poorly understood. This study elucidates the regulatory effects of DHMBA on adipogenesis in mouse 3T3-L1 adipocytes in vitro. The 3T3-L1 preadipocytes were cultured in DMEM containing 10% calf fetal serum in the presence of DHMBA. Culturing with DHMBA repressed the growth of 3T3-L1 preadipocytes cultured in a medium without differentiation factors. Interestingly, when 3T3-L1 preadipocytes were cultured in a medium including differentiation factors containing insulin, DHMBA did not affect the number of cells with the differentiation process of adipogenesis. Culturing with DHMBA (1, 10, or 100 μM) inhibited lipid accumulation in adipocytes and repressed adipogenesis in 3T3-L1 cells. The potent inhibitory effects of DHMBA on adipogenesis were seen at the later stage of culture. Adipogenesis was inhibited by the presence of wortmannin, PD98059, or Bay 11-7082, which are inhibitors of pathways related to insulin signaling pathway. Notably, the suppressive effects of DHMBA on adipogenesis were expressed by the presence of these inhibitors. DHMBA treatment declined the levels of PPARy and C/EBPα related to preadipocyte differentiation and PI3 kinase 100α, Akt, MAPK, phosphor-MAPK, and mTOR implicated in the insulin signaling pathway, leading to adipogenesis promotion. Thus, DHMBA may inhibit adipogenesis via regulating diverse signaling pathways, providing a new strategy for the therapy of obesity.","PeriodicalId":93800,"journal":{"name":"Nutraceuticals","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44757304","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}

This literature mostly emphasises the ability of PCs to enhance the adaptive upregulation of antioxidant enzymes (AEs), which reduces exercise-associated oxidative stress, but there are several other mechanisms of benefit that this narrative review addresses. These mechanisms include; protecting joints and tendons from physical trauma during exercise; mitigating delayed-onset muscle symptoms (DOMS) and muscle damage; improving muscle and tissue oxygenation during training; cultivating a healthy gut microbiome hence lowering excess inflammation; cutting the incidence of upper respiratory tract viral infections which disrupt training programmes; and helping to restore circadian rhythm which improves sleep recovery and reduces daytime fatigue, which in turn elevates mood and motivation to train.","PeriodicalId":93800,"journal":{"name":"Nutraceuticals","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49603398","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}

In November 2021, the SARS-CoV-2 VoC Omicron emerged and its subvariants BA.1, BA.2 and BA.5 became predominant. Although the protease inhibitor Paxlovid® and the polymerase inhibitors Molnupiravir and Remdesivir were approved as specific antiviral treatment options for COVID-19 patients in the early stages after infection, effective prophylactically acting substances without adverse effects are not available yet. In a recent study, we demonstrated that iota-carrageenan, a sulfated polysaccharide extracted from red seaweed, efficiently inhibits the replication of the SARS-CoV-2 Wuhan Type and the VoCs Alpha, Beta, Gamma and Delta. Now, we extended this study by investigating the antiviral effects of iota-, lambda- and kappa-carrageenans on the VoC Omicron subvariants BA.1, BA.2 and BA.5. Using a VoC Omicron BA.1 spike pseudotyped murine leukemia virus (BA.1 MLVOMVLP) as well as patient-derived SARS-CoV-2 Omicron isolates BA.1, BA.2 and BA.5 (SARS-CoV-2OM BA.1, SARS-CoV-2OM BA.2 and SARS-CoV-2OM BA.5), we demonstrate that iota-carrageenan exhibits similar antiviral activity against all analyzed Omicron subvariants. As with other VoCs shown before, the biologically inert iota-carrageenan was more efficient than kappa- and lambda-carrageenan. Altogether, these results confirm that, independent of the current and potential future variants, the physical barrier provided by iota-carrageenan might be applicable for prophylaxis and early treatment of SARS-CoV-2 infections.","PeriodicalId":93800,"journal":{"name":"Nutraceuticals","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48191048","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}

Techniques used to evaluate and compare the micellar formulations against a non-micellar formula include the following: cryo-SEM to determine morphology; laser diffraction to determine particle size and distribution; zeta potential to determine stability of the particles; solubility assays to determine solubility in water and gastrointestinal media; and Caco-2 cell monolayers to determine intestinal permeability. Results show advantageous features (particle size range in the low micrometres with an average zeta potential of −51.56 ± 2.76 mV), as well as significant improvements in intestinal permeability, in one optimized micellar formula (LipoMicel®).

We provide a descriptive action by which L-serine administration ameliorated the consequences of HFD consumption in relation to weight loss, glucose homeostasis as well as renal mRNA expression of markers of kidney injury. Our results indicated that L-Serine supplementation in drinking water (1%, ad libitum for 12 weeks) in male C57BL/6J mice promoted a significant reduction in body weight, visceral adipose mass (epididymal and retroperitoneal fat pads) as well as blood glucose levels in mice consuming a HFD. In addition, the amino acid significantly reduced the mRNA expression of the Kidney Injury Marker 1 (KIM-1), P2Y purinoceptor 1 (P2RY1), as well as pro-inflammatory cytokines (IL-6 and TNFα). L-serine administration had no effect on mice consuming a standard chow diet.

Microglia senescence was induced by intermittent stimulation of BV2 cells with LPS 500 ng/mL every 72 h for 4 h/day, over a period of 10 days. DKS (100 µg/mL) treatment reduced ß-galactosidase activity and expression, the formation of senescence-associated heterochromatin foci to control levels, and increased cell viability of senescent BV2 (2 folds of control). DSK reduced the expression of Nuclear Factor-kB (NF-kB) (20% lower than control), a key molecule involved in the acquisition of the senescence-associated secretory phenotype (SASP). DKS promoted a neuroprotective effect by increasing the cell viability of SH-SY5Y neuronal cells exposed to the senescent BV2 conditioned medium to values of non-senescent cells. In conclusion, DKS attenuated the senescent microglia phenotype, showing senotherapeutic activity that might be further investigated as adjunctive intervention for obesity and obesity-related neurological disturbances.","PeriodicalId":93800,"journal":{"name":"Nutraceuticals","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45634986","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}
