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

Cyberloafing is the use of (e.g. smartphones, tablets, laptops, and the Internet) for purposes other than work related reasons during work hours. Although cyberloafing in the workplace has been widely investigated, there is relatively a small number of studies on cyberloafing behaviors in educational settings, which refer to students' tendencies to use technology for non-class-related purposes during lectures. The goal of the current study is to determine how frequently and for what purposes speech and language therapy (SLT) students at Biruni University engage in cyberloafing during lectures.

The acute form of unexpected drop in platelet count in children calls for treatment with medications such as corticosteroids, intravenous immunoglobulin (IVIg), and Rho(D) immunoglobulin (anti-DIG). Most of the previous studies have accordingly compared short-term therapeutic outcomes of steroids with those of IVIg. In some cases, IVIg has led to better results. However, there are few studies on the long-term treatment effects of both medicine categories. Ob
