Objective: To investigate the relationship between serum 25(OH) vitamin D and liver fat content in nonalcoholic fatty liver disease (NAFLD).
Methods: A total of 120 patients with NAFLD admitted in our hospital between June and August, 2017 were enrolled and divided into 4 groups with different serum 25 (OH) vitamin D levels: >75 nmol/L (group A, =25), 50-75 nmol/L (group B, =35), 25-50 nmol/L (group C, =32), and < 25 nmol/L (group D, =28). For all the patients, serum 25 (OH) vitamin D level was measured by ELISA, and liver fat content was determined using in-phase opposed-phase TWI sequences. The measurement data were compared among the 4 groups to assess the association between serum 25(OH) vitamin D level and liver fat content.
Results: The liver fat content appeared to be higher in group B (28.66±6.45%) and group C (38.74±11.47%) than in group A (22.79 ± 6.10%), but the difference was not statistically significant (>0.05); the liver fat content in group D (54.79 ± 5.28%) was significantly higher than that in the other 3 groups (>0.05). Liver fat content increased significantly as serum 25(OH) vitamin D level decreased, showing an inverse correlation between them in these patients ( < 0.05, =-0.125).
Conclusions: In patients with NAFLD, a decreased serum 25(OH) vitamin D level is associated with an increased liver fat content, suggesting the value of serum 25(OH) vitamin D as a predictor of NAFLD.

Aims/hypothesis: Fat deposition in the pancreas is implicated in beta cell dysfunction and the progress of type 2 diabetes. However, there is limited evidence to confirm the correlation and explore how pancreatic fat links with beta cell dysfunction in human type 2 diabetes. This study aimed to examine the spatial relationship between pancreatic fat and islets in human pancreases.

Aim: Aging decreases the metabolic rate and increases the risk of metabolic diseases, highlighting the need for alternative strategies to improve metabolic health. Heat treatment (HT) has shown various metabolic benefits, but its ability to counteract aging-associated metabolic slowdown remains unclear. This study aimed to investigate the impact of whole-body HT on energy metabolism, explore the potential mechanism involving the heat sensor TRPV1, and examine the modulation of gut microbiota.

Carotenoids are natural micronutrients found in plants and microorganisms, but not synthesized by animals. Carotenoids show various biological activities, including antioxidant properties, regulation of cell growth, and modulation of gene expression and immune responses. The rising global incidence of fatty liver disease (FLD) and obesity highlights the importance of carotenoids in chronic progressive conditions.

Despite the high frequency of pregnancies complicated by abnormal glucose metabolism associated with obesity, methylmercury (MeHg) metabolism in pregnant women with abnormal glucose metabolism is unclear. We aimed to elucidate the MeHg tissue distribution in obese female mice with abnormal glucose metabolism and their fetuses. Female C57BL/6J mice were fed a high-fat diet (HFD) or a standard diet (Ctrl) for 12 weeks and mated.
