Abstract:
When fabricating a small diameter arterial prosthesis, the performance requirements include controlling dimensions, maintaining a uniform structure, ensuring superior mechanical properties as well as excellent biocompatibility. Material selection and fabricating methods can influence these factors. In this study, three 100% polyester prostheses, three bicomponent polyester/silk prostheses and three 100% silk prostheses were woven into seamless tubular prototype prostheses with three different basic weaves. After degumming/scouring they met the target inner diameter of 3.83 ± 0.30 mm which demo

Abstract:
In the market for products for the needs of cardiovascular surgery, there is still no effective vascular prosthesis with a diameter of less than 4 mm, despite the continuous increase in the incidence of atherosclerosis and the increase in the number of surgical operations to restore blood flow in the affected arteries. At the same time, vascular tissue engineering has diverse methodological approaches for the development of effective functionally active small-diameter vascular prostheses suitable for adaptive growth and regeneration in situ. An important aspect is the possibility of personaliz

Oral rehabilitation with fully ceramic implant-supported prostheses is one of the treatment options that presents clinical longevity and patient satisfaction. However, complications regarding the chipping are reported in the literature. To reduce these problems, the use of monolithic zirconia is constantly suggested. Another option, not so reported, are the modifications in the final configuration of the cover ceramic. The design of the chosen materials is discussed.

Abstract:
Regenerative grafts for myocardial reconstruction are often mechanically not stable enough to withstand the left ventricle’s high blood pressure. Hence, decellularized pericardium may serve as a stabilizing structure for biological myocardium prostheses. The efficacy of detergent- and enzyme-based protocols to decellularize porcine pericardium was compared. Then, the decellularized pericardium was employed for a primary cover of a transmural left ventricular defect in minipigs (n = 9). This pericardium patch was applied to mitigate the high-pressure load on an autologous stomach tissue, which

Such preoccupation calls into larger question what really is at the core of human identity. As protagonist Martin Howe adjusts to the r

Abstract:
In prosthesis-based breast reconstruction, surgeons select the sub-muscle layer for implant placement, but the pectoralis major muscle is not sufficient to cover the implant. The pectoralis major muscle does not reach the inframammary sulcus line, so the muscle pockets for implant inevitably have defects. From 2016 to 2019, we performed direct-to-implant (DTI) breast reconstruction for 123 patients, during which the implant was placed partially under the muscle plane and the inferior-lateral portion was placed directly underneath the skin flap.

This study has been carried out in two stages to carefully examine how the implant's fit, the bone's structure, and vibrations are all connected. In the first stage, which this paper covers, a straightforward computer model of the femur was used.
