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

The aim of the study was to define and compare the quality properties of dry-cured heat-treated meat products from the meat of free-living semi-aquatic wildlife species. Eurasian beaver (Castor fiber) and nutria (Myocastor coypus) are wild animals whose presence in the countryside is regulated in the Czech Republic. Basic chemical, microbiological, sensory analyses, and instrumental measurements of the colour and texture of dry-cured sausages (pork, as a control group with 51% lean pork and experimental groups with 51% lean beaver and nutria meat in fresh state) were performed.

Using an updated and significantly augmented sample of Cepheid and tip of the red giant branch (TRGB) distances to 28 nearby spiral and irregular galaxies, covering a wide range of metallicities, we have searched for evidence of a correlation of the zero-point of the Cepheid period–luminosity relation with H ii region (gas-phase) metallicities. Our analysis, for the 21 galaxies closer than 12.5 Mpc, results in the following conclusions: (1) The zero-points of the Cepheid and TRGB distance scales are in remarkably good agreement, with the mean offset in the zero-points of the most nearby distan
