Substitution of mandibular defects resulting from injuries and inflammatory bone diseases as well as surgical interventions for tumors is an important medical and scientific problem. The article presents the results of surgical treatment of 8 patients with the use of combined endoprosthesis of the mandible consisting of individual titanium metal structure and titanium silk. This solution provides the possibility for reliable fixation of the soft tissue structures of the lower face region by suturing, including facial and masticatory muscles, improving the biological integration of the endoprosthesis. The combined design shows high efficiency of restoration of both aesthetic and functional characteristics of the mandible, as well as good long term survival rate.

Advancements in cryo-EM have stimulated a revolution in structural biology. Yet, for membrane proteins near the cryo-EM size threshold of approximately 40 kDa, including transporters and G-protein coupled receptors, the absence of distinguishable structural features makes image alignment and structure determination a significant challenge. Furthermore, resolving more than one protein conformation within a sample, a major advantage of cryo-EM, represents an even greater degree of difficulty.

To evaluate the safety and efficacy of cataract extraction combined with multifocal intraocular lens (IOL) optic implantation in Berger space in school-age children with cataracts. It was a prospective study. The clinical data of school-age children with cataract who underwent cataract extraction combined with multifocal IOL implantation at Qingdao Eye Hospital of Shandong First Medical University from January 2019 to June 2023 were collected.

Purpose: This study aims to investigate the suitable surgical strategies for applying TaBw01 porous tantalum rod across different stages of osteonecrosis of the femoral head (ONFH).
Methods: TaBw01 tantalum rods were fabricated using type FTaY-1 tantalum powder via the foam impregnation-sintering method. Mechanical testing with the Instron 8801 universal testing machine and finite element analysis (FEA) assessed single tantalum rod implantation and impaction bone grafting combined with rod implantation.

Vaginal reconstruction is necessary for various congenital and acquired conditions, including vaginal aplasia, trauma, tumors, and gender incongruency. Current surgical and non-surgical treatments often result in significant complications. Decellularized vaginal matrices (DVMs) from human tissue offer a promising alternative, but require effective sterilization to ensure safety and functionality.
