Background And Objectives: Breast cancer is the second leading cause of death and one of the most common malignancies among women in the world. The aim of this study was to investigate the preventive effects of postbiotic consisting of sonicated cells on triple negative breast cancer.
Materials And Methods: Thirty-six female BALB/c mice aged 5-7 weeks were randomly divided into 3 groups (n=12): Ctrl-, healthy mice; Ctrl+, mice with breast cancer with no treatment; and Postbiotic, mice with orally gavage postbiotic before and after 4T1 cell line transplantation. Cancer progress and the effects of postbiotic were assayed by histological, immunohistochemical and gene expression quantification.
Results: The histological results showed that administration postbiotic consisting of significantly decreased carcinogenesis in terms of tumor incidence, multiplicity and volume. The tumor progress was suppressed by oral intake of as showed by p53 and Ki-67 expression. Furthermore, Oral intake of postbiotic resulted in extended survival of mice and inhibited sever weigh loss.
Conclusion: Pretreatment with sonication killed as a postbiotic, inhibited breast cancer progress and malignancy.

Growing interests in replacing conventional preservatives and antibiotics in food and pharmaceutical industries have driven the exploration of bacterial metabolites, especially those from strains with generally recognized as safe (GRAS) status, such as lactic acid bacteria (LAB). In this study, a supernatant cocktail derived from multiple LAB strains was prepared and its bioactivities-antimicrobial, antibiofilm, antioxidant, cytotoxicity, and stability-were thoroughly investigated. The cocktail's main components were identified using thermal and protease treatments, gas chromatography coupled to mass spectrometry (GC-MS), and flame ionization detection (GC-FID).

Background: Since the gut microbiota is important for athlete health and performance, its optimization is increasingly gaining attention in sports nutrition, for example, with whole fermented foods. Sauerkraut is a traditional fermented food rich in pro-, pre-, and postbiotics, which has not yet been investigated in the field of sports nutrition.
Methods: To determine whether sauerkraut could be used for gut microbiota optimization in sports nutrition, a proof-of-concept study was conducted.

Obesity is a global epidemic and a significant risk factor for various diseases. Obesity and dysbiosis are associated, drawing attention to the mechanisms that regulate the gut microbiota. In this study, we focused on the postbiotic effects of rice kefiran (Kef), a functional product of cultured in a rice-based medium, on obesity and its complications.

Preeclampsia (PE) is a serious complication of pregnancy linked to endothelial dysfunction and an imbalance in the gut microbiota. While (AKK) has shown promise in alleviating PE symptoms, the use of live bacteria raises safety concerns. This study explored the potential of pasteurized (pAKK) as a safer alternative for treating PE, focusing on its effects on endothelial function and metabolic regulation.

The Eurasian wild boar () is a key wildlife host for tuberculosis (TB) in central and southwestern Spain, posing a challenge to TB eradication in livestock. New strategies, including the use of beneficial microbes, are being explored to mitigate wildlife diseases. This study evaluated the effect of oral supplementation with postbiotic antimycobacterial metabolites produced using Ingulados' lactic acid bacteria (LAB) collection on TB development in wild boar.
