Purpose We performed a qualitative study to understand psychosocial factors associated with perceived success of upper-extremity vascularized composite allotransplantation (VCA). interviewed transplant recipients and their primary caregivers. Methods recruited 4 VCA caregivers for 3 them. conducted semistructured face-to-face interviews using guide that explored participants’ transplantation ex...

PURPOSE: Developing novel treatment concepts to minimize/avoid immunosuppression by induction of immune tolerance represents the prime task in the field of transplantation. In the clinic to date, this was achieved in highly selected patients in clinical trials of kidney transplantation combined with concomitant stem cell or bone marrow transplantation. Vascularized composite allotransplantation...

Vascularized composite allotransplantation for the forearm is a complex surgical procedure, requiring multidisciplinary collaboration. It is important to provide optimal blood flow to the grafts, effective immunosuppression, and early rehabilitation for graft survival and good functional outcomes. As ischemia-reperfusion injury and substantial but unquantifiable blood loss are inevitable in thi...

Several andrological diseases require surgical repair or reconstruction of tunica albuginea, which envelops the corpora cavernosa penis. Despite intense research efforts involving a variety of biological materials, such as skin, muscle aponeurosis, human dura mater, tunica vaginalis, and pericardium, engineered tunica albuginea suitable for graft use is yet to be obtained. The study investigate...

Vascularized Composite Allotransplantation (VCA) such as hand and face transplants represent a viable treatment option for complex musculoskeletal trauma and devastating tissue loss. Despite favorable and highly encouraging early and intermediate functional outcomes, rejection of the highly immunogenic skin component of a VCA and potential adverse effects of chronic multi-drug immunosuppression...

The occurrence of Syagrus inajai (Spruce) Becc., popularly known as pupunha palm, among other names, has been registered in the Guianas and in the North of Brazil in areas of terra firme (non-flooding) and gallery forests. In order to characterize the inflorescence and further knowledge of this family, a morphoanatomical study was carried out of the palm S. inajai in a green area of the Campus ...

Acute skin rejection in vascularized composite allotransplantation (VCA) is the major obstacle for wider adoption in clinical practice. This study utilized computational modeling to identify biomarkers for diagnosis and targets for treatment of skin rejection. Protein levels of 14 inflammatory mediators in skin and muscle biopsies from syngeneic grafts [n = 10], allogeneic transplants without i...

THE ultimate test of viability of separated human islets is functional activity after transplantation into a diabetic recipient. Morphologic identification of insulin-containing transplanted islets could provide important correlative data and eventually confirm the functional results. The present report describes identification of intrahepatic islet tissue following human islet allotransplantat...

This is an original research of penis allotransplantation. The paper presents an experiment allogenic penis transplantation model in Beagles, with a focus on recovery of blood supply and changes in tissue architecture. Twenty adult Beagles were allocated to 10 pairs for penile transplantation. After operation, the skin and glans were observed. If adverse symptoms occurred, the transplanted peni...
