Black chokeberry ( L.) is rich in polyphenols with various physiological and pharmacological activities. However, the relationship between the modulation effect of black chokeberry polyphenols on obesity and the alteration of lipid metabolism is not clearly understood. This study aimed to investigate the beneficial effects of the black chokeberry polyphenols (BCPs) treatment on the structure of gut microbiota, lipid metabolism, and associated mechanisms in high-fat diet (HFD)-induced obese rats. Here, we found that a high-fat diet promoted body weight gain and lipid accumulation in rats, while oral BCPs supplementation reduced body weight, liver, and white adipose tissue weight and alleviated dyslipidemia and hepatic steatosis in HFD-induced obese rats. In addition, BCPs supplementation prevented gut microbiota dysbiosis by increasing the relative abundance of , and and decreasing the relative abundance of and . Furthermore, 64 lipids were identified as potential lipid biomarkers through lipidomics analysis after BCPs supplementation, especially PE (16:0/22:6), PE (18:0/22:6), PC (20:3/19:0), LysoPE (24:0), LysoPE (24:1), and LysoPC (20:0). Moreover, our studies provided new evidence that composition of gut microbiota was closely related to the alteration of lipid profiles after BCPs supplementation. Additionally, BCPs treatment could ameliorate the disorder of lipid metabolism by regulating the mRNA and protein expression of genes related to the glycerophospholipid metabolism signaling pathway in HFD-induced obese rats. The mRNA and protein expression of PPARα, CPT1α, EPT1, and LCAT were significantly altered after BCPs treatment. In conclusion, the results of this study indicated that BCPs treatment alleviated HFD-induced obesity by modulating the composition and function of gut microbiota and improving the lipid metabolism disorder the glycerophospholipid metabolism signaling pathway.

Background And Aims: Oral microbiota may contribute to the development of upper gastrointestinal (UGI) disorders. We aimed to study the association between the microbiome of saliva, subgingival and buccal mucosa, and UGI disorders, particularly precancerous lesions. We also aimed to determine which oral site might serve as the most effective biomarker for UGI disorders.

Increasing evidence suggests that dysbiosis of gut microbiota exacerbates chronic kidney disease (CKD) progression. Curcumin (CUR) has been reported to alleviate renal fibrosis in animal models of CKD. However, the relationship between CUR and gut microbiome in CKD remains unclear.

Introduction: Pulmonary fibrosis (PF) is a chronic and irreversible interstitial lung disease characterized by a lack of effective therapies. Mesenchymal stem cells (MSCs) have garnered significant interest in the realm of lung regeneration due to their abundant availability, ease of isolation, and capacity for expansion. The objective of our study was to investigate the potential therapeutic role of umbilical cord-derived MSCs (UC-MSCs) in the management of PF, with a focus on the alterations in the gut microbiota and its metabolites during the use of UC-MSCs for the treatment of pulmonary fibrosis, as well as the possible mechanisms involved.

Objectives: The aim of the study was to explore the alteration of microbiota and SCFA in gut and inflammation in acute exacerbation chronic obstructive pulmonary disease (AECOPD) patients, and to test the hypothesis that a disorder of gut microbiota will lead to the alteration of SCFA, which will aggravate inflammation in AECOPD patients.
Methods And Results: 24 patients with AECOPD and 18 healthy volunteers were included in the study. Gut microbiota were analyzed by 16S rDNA and serum was used to detect levels of inflammatory factors by ELISA.

Purpose: Previous researches have suggested an important association between gut microbiota (GM) and vascular pathologies such as atherosclerosis. This study aimed to explore the association between 196 GM taxa and retinal vein occlusion (RVO).
Methods: This study used Mendelian randomization (MR), linkage disequilibrium score regression (LDSC), and polygenic overlap analysis.
