The number of organ donors in Sweden is not enough to cover the need of tissues for transplant purposes. Other sources have to be defined. Young and healthy potential donors can be identified within DFM. Without precise written agreements and a well-educated and trained organization those donations will not be realized. With the purpose to evaluate national efforts to establish close cooperation between tissue establishments and DFM, two surveys were conducted at two time periods, 2011-13 and 2014-16. A total of 2118 pieces of tissue were retrieved within 6 years, 1799 for transplant purposes and 319 for research or education. Most common tissues were heart valves and cornea but also skin and ear bones were collected. 23% of all retrieved tissue from deceased donors in Sweden came from DFM. In the first period 19 % of all transplanted tissue came from DFM and in the latter period it had increased to 26%. Education and national courses for employees in DFM as well as logistic and economical support from national authorities are important factors for building a stable organization and for sustainable progress.

The identification of immune environments and cellular interactions in the colon microenvironment is essential for understanding the mechanisms of chronic inflammatory disease. Despite occurring in the same organ, there is a significant gap in understanding the pathophysiology of ulcerative colitis (UC) and colorectal cancer (CRC). Our study aims to address the distinct immunopathological response of UC and CRC.

We herein report a microwave-assisted Buchwald-Hartwig double amination reaction to synthesize potential thermally activated delayed fluorescence compounds, forming C(sp)-N bonds between donor and acceptor units. Our approach reduces reaction times from 24 h to 10-30 min and achieves moderate to excellent yields, outperforming conventional heating methods. The method is compatible with various aryl bromides and secondary amines, including phenoxazine, phenothiazine, acridine, and carbazole.

Background: The possibility of future parenthood is a highly relevant issue for patients of reproductive age facing oncologic treatment. This study aimed to investigate how fatherhood was achieved in a patient cohort of adolescents and young adults (AYAs) banking semen at time of cancer diagnosis and to determine the effectiveness of cryopreservation aimed at fertility preservation in the cohort.
Materials And Methods: Observational cohort study examining AYAs with a cancer diagnosis who underwent semen banking for fertility preservation at Karolinska University Hospital 1988-2020, as part of the Stockholm regional fertility preservation program.

Background: Several countries have either developed or are developing national induced pluripotent stem cell (iPSC) banks of cell lines derived from donors with HLA homozygous genotypes (two identical haplotypes) prevalent in their local populations to provide immune matched tissues and cells to support regenerative medicine therapies. This 'haplobank' approach relies on knowledge of the HLA genotypes of the population to identify the most beneficial haplotypes for patient coverage, and ultimately identify donors or cord blood units carrying two copies of the target haplotype.
Aims: A potentially more efficient alternative to a national bank approach is to assess the haplotypes required to provide global patient coverage and to produce a single, global haplobank.

Background: Transplantation of cells, tissues, and organs enables many patients to regain impaired organ function, promoting healing or prolonging life and improving overall quality of life.
Objective: The aim of this study was to assess the knowledge and attitudes of students in Federation of Bosnia and Herzegovina regarding organ donation and transplantation of organs.
Methods: A cross-sectional study was carried out with 255 students from four different faculties in Federation of Bosnia and Herzegovina, with the majority enrolled in either the Faculty of Medicine or the Faculty of Health Sciences.
