Tissue transplantation is more common than organ transplantation. Legislative changes in 1996 transformed tissue banking and conditions for tissue transplantation in Sweden. After an initial decrease in donated tissue, heart valves are now available in sufficient numbers, but there is sometimes a shortage of valves the right size for pediatric cardiac surgery. Since the new transplantation legislation was implemented there has been an increase in the number of valves from neonatal donation and after sudden infant death. The number of donated corneas does not correspond to the number required for transplantation. A number of tissue coordinators have been established throughout the country and recently some new tissue banks were founded to increase the amount of tissue available for transplantation. The organization of the tissue bank in Lund is described. There is a lack of knowledge about tissue transplantation and donation among health professionals as well as the general public, and more education is warranted.

Long-term, immunosuppression-free allograft survival has been induced in human and nonhuman primate (NHP) kidney recipients after nonmyeloablative conditioning and donor bone marrow transplantation (DBMT), resulting in transient mixed hematopoietic chimerism. However, the same strategy has consistently failed in NHP heart transplant recipients. Here, we investigated whether long-term heart allograft survival could be achieved by cotransplanting kidneys from the same donor.

Purpose: Optimal management of retroperitoneal soft tissue sarcoma (RPS) often requires extensive tumor resections, frequently involving gastrointestinal organs. The impact of these procedures on the nutritional status and hemoglobin (Hb) levels of RPS patients remain unexplored. In this study, we aimed to evaluate preoperative nutritional status as well as the prevalence of anemia in RPS patients, and to investigate longitudinal changes throughout the disease course in order to identify potential strategies for prehabilitation.

Objectives: To study the clinical effect of the L-shape technique combined with concentrated growth factor on the horizontal bone defects of maxillary anterior teeth.
Methods: Twenty-five implants from 25 patients who underwent single maxillary anterior tooth implantation with simultaneous bone grafting were selected as the study subjects. Based on the bone grafting techniques, the patients were divided into a test group (L-shaped technique with guided bone regeneration combined with concentrated growth factor, 11 cases) and a control group (traditional guided bone regeneration combined with concentrated growth factor, 14 cases).

Cell-instructive polymer hydrogels are instrumental in tissue engineering for regenerative therapies. Implementing defined and selective responsiveness to external stimuli is a persisting challenge that critically restricts their functionality. Addressing this challenge, this study introduces a versatile, modular hydrogel system composed of four-arm poly(ethylene glycol)(starPEG)-peptide and glycosaminoglycan(GAG)-maleimide conjugates.

Objective: To discover the potential association between diminished intraoperative average SctO levels and postoperative neurodevelopmental delays among patients after pediatric living-donor liver transplantation.
Study Design: Patients undergoing living-donor liver transplantation were recruited for this trial. The neurodevelopment status of patients was assessed using the Ages Stages Questionnaires.
