Article Abstract
High-fat diets (HFD) adversely affect organ systems. Several studies have examined HFD-related disorders in animals but only in a few organs and time points. Herein, we evaluated disease development with time-dependent HFD-induced pathological, cardiovascular, and morphological changes in rabbits with lipid metabolism similar to that in humans for 9 weeks. The body weights and waist ratio of the HFD group were higher than those in the control group. HFD significantly increased the total cholesterol, low-density lipoprotein, high-density lipoprotein, and phospholipid levels after 3 weeks. Liver enzyme levels increased with hepatomegaly, steatosis, and fibrosis after 3 or 6 weeks. RBCs and hemoglobin decreased, while platelets increased in the HFD group with atherosclerosis and inflammatory cell infiltration in the aorta after 6 weeks. Ejection fraction and fractional shortening values decreased in the HFD group after 9 weeks. Creatinine increased with glomerulosclerosis in the kidneys of the HFD groups after 3 weeks, indicating renal dysfunction. Lipid accumulation was found in the pancreas after 9 weeks. Lipid accumulation and hypertrophy were observed in the adrenal glands after 3 weeks. Overall, our findings provide global reference data on the time-dependent effects of HFD on the body and may serve as a guide for future HFD risk prevention.

Type 2 diabetes mellitus (T2DM) is a a complex metabolic disorder that poses a serious threat to human health. Although polyphenol extract from rapeseed meal (RMP) has demonstrated inhibitory activity against α-glucosidase, the alleviating effects on T2DM and the underlying molecular mechanisms remain largely unexplored in T2DM. In this study, the antidiabetic effects of RMP were investigated using a T2DM mouse model induced by a high-fat diet (HFD) combined with streptozotocin (STZ) administration.

Background: Obesity is associated with hormonal imbalance, increased oxidative stress, and inflammation in the testis. These conditions adversely affect sperm quality, leading to impaired male fertility. Therefore, therapeutic interventions to counteract the adverse effects of obesity are crucial.

Objectives: Recent evidence suggests that the gut may be a primary site of metformin action. However, studies on the effects of metformin on gut microbiota remain limited, and its impact on gut microbial metabolites such as short-/medium-chain fatty acids is unclear. This study aims to investigate the effects of metformin on gut microbiota, short-/medium-chain fatty acids, and associated metabolic benefits in high-fat diet rats.

Objectives: To investigate the therapeutic effect of electroacupuncture (EA) at Zusanli (ST36) acupoint on hyperlipidemia in mice and explore the underlying mechanisms.
Methods: Thirty C57BL/6J mice were equally randomized into normal diet group, high-fat diet (HFD) group, and EA group. The changes in blood lipids and serum malondialdehyde (MDA) content of the mice were evaluated, and histopathological changes and lipid accumulation in the liver were observed using Oil red O staining (ORO).
