Diseases and injuries can cause significant bone loss, leading to increased medical expenses, decreased work efficiency, and a decline in quality of life. Bone tissue engineering (BTE) is gaining attention as an alternative to autologous and allogeneic transplantation due to the limited availability of donors. Biomaterials represent a promising strategy for bone regeneration, and their design should consider the three key processes in bone tissue engineering: osteogenesis, bone conduction, and bone induction.

Multiple sclerosis (MS) is a severe autoimmune disorder that wreaks havoc on the central nervous system, leading to a spectrum of motor and cognitive impairments. There is no cure, and current treatment strategies rely on broad immunosuppression, leaving patients vulnerable to infections. To address this problem, our approach aims to induce antigen-specific tolerance, a much-needed shift in MS therapy.

Background: Ulcerative colitis (UC) is a chronic inflammatory condition requiring continuous treatment and monitoring. There is limited pharmacokinetic data on vedolizumab during maintenance therapy and the effect of thiopurines on vedolizumab trough concentrations is unknown.
Aim: To investigate the exposure-response relationship of vedolizumab and the impact of thiopurine withdrawal in UC patients who have achieved sustained clinical and endoscopic remission during maintenance therapy.

Introduction: Inflammatory bowel disease patients are exposed to frequent procedures and hospital admissions as well as recurrent need for radiological examinations with a high risk of exposure to radiation and contrast.
Aim: Our objective was to evaluate the role of a combination of both intestinal ultrasound (IUS) and colour Doppler with different parameters for monitoring changes in inflammation over time and to reveal their potential role in the assessment of response to biologic therapy in inflammatory bowel disease (IBD) patients.
Material And Methods: Before the induction of biological therapy, IUS together with colour Doppler of the intestine was conducted.
