General information and anthropometric and blood biochemical indices were recorded, including gender, age, body mass index, mid-arm muscle circumference, albumin, intact parathyroid hormone, and Ca and P product (Ca×P). The severity of vascular calcification was graded. The correlation between the severity of vascular calcification in patients and each of the clinical indicators was analyzed. The diagnostic value of Ca and P metabolism and microinflammatory factors for vascular calcification in malnourished uremic patients was assessed. All enrolled patients were divided into a non-vascular calcification group (n=42) and a vascular calcification group (n=36) according to coronary artery calcification (CAC) scoring, and the probability of vascular calcification was 46%. The dialysis duration, Ca×P, P, hypersensitive C-reactive protein (hs-CRP), and interleukin 6 (IL-6) levels were significantly higher in the vascular calcification group than in the non-vascular calcification group. hs-CRP, IL-6, Ca×P, and P had predictive potency for vascular calcification in patients. CAC scores were correlated positively with hs-CRP, IL-6, Ca×P, and P. Malnourished uremic patients have a higher incidence of vascular calcification. hs-CRP, IL-6, Ca×P, and P are all independent risk factors for vascular calcification in uremic patients, and are positively correlated with the severity of vascular calcification.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"71 2","pages":"148-154"},"PeriodicalIF":0.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144014298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The transient receptor potential melastatin 8 (TRPM8) channel, a cold receptor, plays a critical role in cold perception and thermoregulation. Menthol, which activates TRPM8, has been shown to promote the \"browning\" of white adipocytes, enhancing thermogenesis. However, its effect on autonomic thermoregulation has remained unclear. To address this, the present study examines the influence of dietary menthol intake on autonomic thermoregulation in mice, with a focus on body temperature regulation under cold conditions. In this experiment, mice were fed diets containing 0.25% and 0.5% menthol for either 2 or 4 wk. The results indicated that the 0.5% menthol diet significantly reduced food intake, body weight, and visceral fat. In contrast, the 0.25% menthol diet showed no significant impact on these factors. Notably, mice treated with the 0.25% menthol diet for 4 wk suppressed the decrease in rectal and interscapular brown adipose tissue (IBAT) temperatures in a cold environment under anesthesia. Additionally, TRPM8 gene expression in IBAT was upregulated after 4 wk of 0.25% menthol diet consumption. These findings suggest that dietary menthol, especially at low concentrations, improves autonomic thermoregulation by activating TRPM8 without significantly affecting food intake or body weight.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"71 2","pages":"173-179"},"PeriodicalIF":0.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144022600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While some studies suggest that elevated acylcarnitine levels are linked to cardiovascular events, limited data are available on the relationship between free carnitine levels and clinical outcomes in heart failure patients. This study aimed to investigate the association between free carnitine levels and clinical outcomes in patients hospitalized for heart failure. This retrospective study included 271 consecutive patients admitted to our hospital for their first episode of acute heart failure. Patients were divided into four quartiles based on free carnitine levels (quartile 1: <37.0 μmol/L, n=69; quartile 2: 37.0-49.7 μmol/L, n=68; quartile 3: 49.7-58.9 μmol/L, n=67; quartile 4: ≥58.9 μmol/L, n=67). The primary endpoints were 1-y cardiac mortality, rehospitalization due to heart failure, and its composite endpoint. The incidence of cardiovascular events was compared among the quartiles. Creatinine levels were significantly higher in quartile 4 than in other groups. There were no significant differences in age or BNP among the four groups. Additionally, the 1-y mortality rate was significantly higher in both quartile 1 and quartile 4, while the rehospitalization rate for heart failure within 1 y post-discharge was significantly higher in quartile 4. In summary, the relationship between free carnitine levels and mortality in heart failure patients showed a J-curve pattern, with both low and high levels associated with worse outcomes. Thus, extreme free carnitine levels may serve as potential risk factors for adverse clinical outcomes in this population.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"71 2","pages":"140-147"},"PeriodicalIF":0.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143996629","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Accordingly, this pilot study aimed to investigate the effects of pterostilbene on blood biochemistry and blood miRNA expression levels and the safety of continuous intake at doses of 10 or 100 mg/d over 12 wk. A double-blind, placebo-controlled parallel-arm comparison trial was conducted with 30 healthy men.

Following OVA sensitization, the mice received 5% Kes and Inu, either individually or a combined 2.5% dose of each, for 4 wk. We assessed allergy-related markers, such as OVA-specific serum IgE (OVA-sIgE) levels, in the blood and monitored changes in the gut microbiome. The intake of fructans ameliorated allergic symptoms and stabilized rectal temperatures, with a significant reduction in OVA-sIgE levels only in the combined Kes and Inu group (Kes+Inu), p<0.05. Gut microbiota diversity analysis revealed significant differences in beta diversity between the groups not receiving fructans and those receiving Kes, Inu, or Kes+Inu (p<0.01 each). Specifically, in the Kes+Inu group, the abundance of the genus UBA7173 belonging to the family Muribaculaceae significantly increased. Additionally, acetate levels were significantly elevated only in the Kes+Inu group and correlated positively with the presence of the genus UBA7173. These findings indicated that the combined intake of Kes and Inu improves allergic outcomes, positively affects the gut microbiome, and enhances the production of acetate.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"71 3","pages":"238-247"},"PeriodicalIF":0.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144528342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the occurrence of diabetes in KK-Ay mice, a model for type 2 diabetes, the most common form of diabetes, remains unclear. Although this mouse can synthesize AsA, understanding its level changes during diabetes progression could help in analyzing AsA's effects on type 2 diabetes. Therefore, the present study investigated the relationship between hyperglycemia and AsA concentrations in the blood and organs of KK-Ay mice, and discussed the findings in relation to those observed in STZ-diabetic mice. Male KK-Ay mice were examined at different stages of diabetes (pre-diabetic, early onset, and hyperglycemic maintenance). STZ-diabetic mice were generated by administering STZ to ICR mice. AsA concentrations were measured in plasma, blood mononuclear cells, and tissues, along with hepatic L-gulonolactone oxidase (GLO) activity and mRNA expression levels. Unexpectedly, AsA concentrations in KK-Ay mice increased under hyperglycemic conditions, while they decreased in STZ-diabetic mice. A consistent relationship was not observed between organ AsA concentrations and hyperglycemia. GLO activity and mRNA expression levels increased in KK-Ay mice, but decreased in STZ-diabetic mice, suggesting an innate defense mechanism against hyperglycemia in KK-Ay mice. These results indicate that different diabetes models exhibit distinct changes in AsA concentrations and hepatic GLO activity under hyperglycemic conditions, highlighting the importance of considering endogenous AsA when evaluating the antioxidant properties of dietary components in KK-Ay mice.","PeriodicalId":16624,"journal":{"name":"Journal of nutritional science and vitaminology","volume":"71 2","pages":"101-109"},"PeriodicalIF":0.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144005723","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
