Ethnopharmacological Relevance: Panax notoginseng (Burkill) F.H.Chen(P. notoginseng) has been widely used as an herbal medicine for reducing swelling, relieving pain, promoting blood circulation and stopping bleeding, with notable therapeutic effects on obesity, liver diseases, colitis, Alzheimer's disease, chronic kidney disease and other diseases.
Aim Of The Study: This review highlighted the close link and bidirectional effects between P. notoginseng and gut microbiota, with the ultimate aim of providing new insights into the potential mechanisms of pharmacological effects of P. notoginseng in the treatment of different diseases and PNS transformation.
Materials And Methods: By means of some reputable databases (PubMed, China National Knowledge Infrastructure (CNKI), Google Scholar, etc.), we screened the published articles related to P. notoginseng from 1998 to 2024, including original research, clinical trials and review on raw materials and chemical constituents of P. notoginseng. Then, we employed the keywords "gut microbiota", "intestinal microbiota", "gut biotransformation" and "intestinal" to exclude the articles that do not in line with our topic. Plant information was obtained from www.worldfloraonline.org using "Panax notoginseng (Burkill) F.H.Chen" as the keyword.
Results: P. notoginseng elevated certain probiotics including Lactobacillus, Bifidobacterium and Akkermansia, while simultaneously reducing pathogenic bacteria such as Prevotellaceae, Enterococcus, Enterobacter and Helicobacter, to fight various diseases. Meanwhile, considering to the low oral bioavailability and degradable properties of Panax notoginseng saponin (PNS), gut microbiota converted it into protopanaxatriol(PPT) and protopanaxadiol(PPD) mainly through deglycosylation reactions to enhance the bioactivity.
Conclusion: Increasing evidences suggest that gut microbiota may play a vital role for P. notoginseng exerting on beneficial effects on the prevention and treatment of metabolic disorders, liver diseases, neurological diseases, chronic kidney diseases, vascular diseases, colitis, and other diseases, as well as for biotransformation of P. notoginseng.

Dietary profiles of wild carnivores and Blastocystis occurrence: The case of the endangered Iberian lynx (Lynx pardinus) and systematic review.

Recent molecular and metagenomic studies have revealed that the obligate anaerobic protist Blastocystis is found more prevalently and with higher subtype diversities in herbivore species than in carnivore species. However, information on wild carnivore species is scarce. Here, we investigated the presence of Blastocystis by molecular methods in fecal DNA samples of free-ranging and captive Iberian lynxes from Spain (n = 243) and Portugal (n = 30).

In this study, male Sprague-Dawley (SD) rats were exposed to bisphenol S (BPS) at environmentally relevant concentrations to investigate its reproductive toxicity and evaluate its effects on the gut-blood-testicular axis. After 28 days of exposure to BPS (0.05 and 20 mg/kg), the results showed a reduction in weight gain and the induction of reproductive toxicity in male rats, including decreased sperm parameters, lower sperm viability, and increased abnormal sperm density and mortality.

Background: Presently, the mitigation and governance of obesity have surfaced as significant public health dilemmas on a global scale. A wealth of studies indicated that the host gut microbiota is instrumental in regulating the interplay between high-fat diet (HFD) intake and the pathogenesis of obesity. Physiological premature fruit drop, a major byproduct of citrus, is rich in a variety of bioactive constituents, yet its potential has remained underutilized for an extended period.

Background: Among all gynecological cancers, ovarian cancer is the leading cause of death. Epithelial ovarian cancer (EOC) accounts for over 85 % of ovarian cancer cases and is characterized by insidious onset, early metastasis, and a high recurrence rate. Alterations in gut microbiota, often as a consequence of chemotherapy, can promote cancer development and exacerbate the disease.

Indole-3-propionic acid (IPA), a metabolite produced by gut microbiota through tryptophan metabolism, has recently been identified as playing a pivotal role in bone metabolism. IPA promotes osteoblast differentiation by upregulating mitochondrial transcription factor A (Tfam), contributing to increased bone density and supporting bone repair. Simultaneously, it inhibits the formation and activity of osteoclasts, reducing bone resorption, possibly through modulation of the nuclear factor-κB (NF-κB) pathway and downregulation of osteoclast-associated factors, thereby maintaining bone structural integrity.
