Objectives: Hochst, belonging to the family, is known for its ethnomedicinal values, particularly in treating various diseases in Africa. This study aimed to investigate the antibacterial, antioxidant, and cytotoxic properties of stem bark extracts, with a specific focus on assessing their bioactive potential and identifying active compounds via TLC bioautography.
Methods: The antimicrobial activity was assessed using the agar well diffusion method against selected clinical strains.
In vitro characterization of lactic acid bacteria and bifidobacteria from wild and domestic pigs: probiotic potential for post-weaning piglets.

Veterinary Research Institute, Hudcova 296/70, Brno, 621 00, Czech Republic.
Background: Gastrointestinal diseases in weaned piglets are a frequent cause of high morbidity and mortality in domestic pigs. The use of antibiotics is problematic due to increasing antibiotic resistance in bacterial populations, for which reason the use of suitable probiotics is highly recommended to maintain animal health and welfare.
Results: In this study, 57 strains of biologically safe lactic acid bacteria (LAB) and bifidobacteria originating from the gastrointestinal tract (GIT) of pigs were identified and characterized in terms of their probiotic properties for potential use in weaned piglets.
Mechanical and optical properties of additively manufactured denture base resin in different colors modified with antimicrobial substances: An in vitro study.

Associate Professor, Department of Restorative, Preventive and Pediatric Dentistry, School of Dental Medicine, University of Bern, Switzerland; and Adjunct Professor, Division of Restorative and Prosthetic Dentistry, The Ohio State University, Columbus, OH.
Statement Of Problem: Acrylic denture base resins are subject to colonization by oral and nonoral bacteria, contributing to the onset of denture stomatitis. However, how the addition of antimicrobial substances affects the mechanical and optical properties of additively manufactured denture base resin remains unclear.
Purpose: The purpose of this in vitro study was to investigate the surface roughness, color stainability, and flexural strength of antimicrobial-modified, additively manufactured polymethyl methacrylate (PMMA) denture base resin in tooth and gingiva colors.
Regulatory role of the mTOR signaling pathway in autophagy and mesangial proliferation in IgA nephropathy.

Department of Nephrology, Second Xiangya Hospital, Central South University, Changsha 410011.
Objectives: IgA nephropathy (IgAN) is the most common primary glomerular disease in China, but its pathogenesis remains unclear. This study aims to explore the regulatory role of the mammalian target of rapamycin (mTOR) signaling pathway in autophagy and mesangial proliferation during renal injury in IgA.
Methods: The activity of mTOR and autophagy was evaluated in kidney samples from IgAN patients and in an IgAN mouse model induced by oral bovine serum albumin and carbon tetrachloride (CCl4) injection.
