An orthopedic bone bank's creation and management is a challenging procedure where medical organization and legal requirements interact. There are no formal regulations for the management and organization of an orthopedic bone bank in the Netherlands or any other nation in Europe. The recently revised "law of security and quality for utilizing human materials in the Netherlands establishes guidelines for the technical and administrative elements of using human tissue and cells. The bone bank's processes involve a rigorous questionnaire for choosing donors, a complete bacteriological, histological, and serological examination, as well as industry-standard, practices for registering, processing, preserving, distributing, and storing bone allografts. This article explains how an approved bone bank is run, and it may be used as a suggestion for formal regulation or as a model for additional orthopedic bone banks in Europe. Osseous graft manufacture, testing, packing, storage, and transportation are all handled by bone banks. Their primary responsibility is to guarantee the transplants' biological characteristics and microbial cleanliness by legal and quality criteria. All orthopedic surgeons face the challenge of reconstructing bone defects; to address this issue, there are several methods, including the use of autografts, allografts, and bone substitutes to enhance and speed bone recovery. Although autografts have superior biological qualities, their volume is constrained and they are linked to donor site morbidity. Allografts are readily accessible, however, there are still worries about the possibility of infections, and they lack osteosarcoma qualities.

Human Tissue Banks (BTH) must validate the storage of collected/processed tissues ensuring physical integrity, sterility, and microbial protection for up to 5 years. (1) Is it safe to use bone tissue for transplants collected by a BTH after 5 years of storage? (2) Do the packaging of stored tissues present physical integrity, sterility, and microbial protection after 5 years? (3) What are the morphological results of bone tissues after 5 years?. 20 femoral heads were used with a storage time of between 9 and 10 years at -80 °C.

We aimed to evaluate the efficacy and safety of sotrovimab in the RECOVERY trial, an investigator-initiated, individually randomised, controlled, open-label, adaptive platform trial testing treatments for patients admitted to hospital with COVID-19.
Methods: Patients admitted with COVID-19 pneumonia to 107 UK hospitals were randomly assigned (1:1) to either usual care alone or usual care plus a single 1 g infusion of sotrovimab, using web-based unstratified randomisation.

Active mechanical metamaterials have the potential to revolutionize material capabilities, by switching between different properties. The active mechanical metamaterial presented here can be remotely programmed to switch between compressive and shear deformation modes that cause stark changes in stiffness. The considered metamaterial uses controlled instabilities to change the buckling mode of electro-thermally activated beams.

Background: Mesenchymal stem/stromal cells (MSCs) or MSC-derived extracellular vesicles (MSC-EVs) are considered potential modulators of the immune system in type 1 diabetes (T1D) therapy. On the other hand, preconditioning MSCs with inflammatory agents is a promising strategy to improve the therapeutic effects of these cells. Therefore, we performed various direct preconditioning regimens (IFN-γ, poly(I: C), LPS, and hypoxia) on clonal MSCs (cMSCs), and for indirect preconditioning regimens, the same regimens were applied to peripheral blood mononuclear cells (PBMCs).

Small round cell sarcomas (SRCS) are highly aggressive tumors in soft tissues and bone of mostly children and young adults. Despite being different in many aspects, including genetics, possible cell-of-origin, and pathology, patients with any of these entities all receive the same therapeutic regimen. Although several pre-clinical models of Ewing sarcoma have been established, such as cell lines and patient-derived tumor xenografts, few models exist for other SRCS.
