Bone tissue exhibits viscoelastic behavior, and stress relaxation analysis provides valuable insight into its time-dependent mechanical performance. This study aimed to evaluate the effects of allicin supplementation on the mechanical and viscoelastic properties of tibial bone in Bovans Brown laying hens. Tibiae of 68-week-old hens were subjected to three-point bending tests to determine quasi-static mechanical properties, as well as stress relaxation tests conducted at three deformation velocities (0.1, 1, and 10 mm/s). Stress relaxation behavior was described using a five-parameter generaliz

Background : The collection of microorganisms that colonize the human genital and urinary tract is referred to as the genitourinary microbiome. Urinary tract infections (UTIs), which predominantly affect women, are linked to alterations in the genitourinary microbiome. Cranberries ( Vaccinium oxycoccos ), rich in proanthocyanidins, and ascorbic acid (vitamin C), known for their urinary acidification properties, are commonly used for UTI prevention. However, their effects on the genitourinary microbiome remain inadequately characterized. This pilot study assesses the genitourinary microbiome co
