Hyperlipidemia has become a prevalent disease in the global epidemic, posing a threat to human health. This study aims to investigate the mechanism by which fermented juice (RRFJ) can prevent lipid deposition induced by a high-fat diet in mice. The results showed that mice in the RRFJ intervention group had significantly reduced body weight as well as lower levels of serum and liver lipid indicators compared to the high-fat diet group. Metagenomic analysis revealed that the RRFJ intervention reversed the decrease in intestinal flora and genes in mice fed a high-fat diet. Liver metabolomics showed that the RRFJ prevented liver dyslipidemia by modulating the biosynthesis of phenylalanine, tyrosine, tryptophan, and phenylalanine metabolism. RRFJ is effective in preventing dyslipidemia through the 'gut-liver axis', which regulates the imbalance of intestinal flora and improves hepatic metabolic profiles. This provides a new intervention strategy for the prevention and treatment of hyperlipidemia.

Background: Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are common bariatric procedures that lead to substantial and sustained weight loss. Although both procedures induce hormonal and physiological effects, RYGB includes both a restrictive and malabsorptive component due to anatomical rerouting, whereas SG is considered primarily restrictive. This study aimed to quantify differences in energy and fat absorption between both procedures using near-infrared spectroscopy (NIRS).

Obesity is a multifactorial disease characterized by excessive accumulation of adipose tissue, resulting from an imbalance between energy intake and expenditure. Mouse models have emerged as invaluable tools for elucidating the complex genetic, environmental, and physiological mechanisms driving to obesity. This chapter provides an overview of the methodologies employed to establish and study obesity in mice, highlighting their relevance to human disease.

Young females have higher circulating docosahexaenoic acid (DHA) levels than males, though the metabolic basis remains incompletely understood. Building on previous findings demonstrating higher hepatic synthesis of the DHA precursor, docosapentaenoic acid (DPAn-3) in males, this study extends the investigation to n-3 PUFA turnover in extrahepatic tissues of male and female C57BL/6N mice using compound-specific isotope analysis (CSIA). Animals were fed a 12-week diet enriched in either α-linolenic acid (ALA), eicosapentaenoic acid (EPA), or DHA, starting with a 4-week phase containing low carbon-13 (δC)-n-3 PUFA, followed by an 8-week phase with high δC-n-3 PUFA (n = 4 per diet, time point, sex).

Introduction: Metabolic dysfunction-associated steatotic liver disease (MASLD) represents an increasing global health problem in association with obesity and insulin resistance without approved pharmacotherapy. Previous studies revealed malic enzyme 1 (ME1) as a susceptibility gene for metabolic disorders in humans. However, the role and mechanisms of ME1 in regulating hepatic lipid metabolism remain largely unclear.

The gut microbiota and its products are recognized as pivotal contributors to the pathogenesis of metabolic-associated fatty liver disease (MAFLD). Shenling Jianpiwei formula (SLJPW), a prescription renowned for its protective effects in intestinal disorders, demonstrates efficacy against MAFLD. However, its underlying mechanisms and chemical composition remain unclear.
