1. Superior Capsular Reconstruction with Fascia Lata Allograft for Irreparable Supraspinatus Tendon Tears
Resumo A reconstrução da cápsula superior é um procedimento descrito recentemente para o tratamento das roturas irreparáveis do tendão do músculo supraespinal. Como opções de enxerto podemos citar o uso de fáscia lata autógena e enxerto dermal acelularizado. Nenhum estudo foi publicado com o uso de aloenxerto de fáscia lata. O objetivo desta nota

2. Horizontal Bone Reconstruction on sites with different amounts of native bone: a retrospective study
Abstract: The lack of guidelines for bone augmentation procedures might compromise decision making in implantology. The objective of this study was to perform a retrospective study to verify the outcomes of horizontal bone reconstruction in implant dentistry with different types of materials and amounts of native bone in the recipient bed to allow for a new

3. Prostate cancer in renal transplant recipients
ABSTRACT As patients with end-stage renal disease are receiving renal allografts at older ages, the number of male renal transplant recipients (RTRs) being diagnosed with prostate cancer (CaP) is increasing. Historically, the literature regarding the management of CaP in RTR's is limited to case reports and small case series. To date, there are no standardiz

5. Associated Clinical and Laboratory Markers of Donor on Allograft Function After Heart Transplant
Abstract Introduction: Primary graft dysfunction is a major cause of mortality after heart transplantation. Objective: To evaluate correlations between donor-related clinical/biochemical markers and the occurrence of primary graft dysfunction/clinical outcomes of recipients within 30 days of transplant. Methods: The prospective study involved 43 donor/rec

6. Lyophilized allografts without pre-treatment with glutaraldehyde are more suitable than cryopreserved allografts for pulmonary artery reconstruction
Various methods are available for preservation of vascular grafts for pulmonary artery (PA) replacement. Lyophilization and cryopreservation reduce antigenicity and prevent thrombosis and calcification in vascular grafts, so both methods can be used to obtain vascular bioprostheses. We evaluated the hemodynamic, gasometric, imaging, and macroscopic and micro

7. An outcome analysis and long-term viability of cryopreserved cultured epidermal allografts: assessment of the conservation of transplantable human skin allografts
PURPOSE: To assess the viability of cultured epithelium and preserved by freezing for periods varying from one month to one year. METHODS: Samples of cultured epithelium were incubated in cryoprotectant medium (Group A), packed in aluminum envelopes and packed in polystyrene boxes. The boxes were subjected to a temperature of-70ºC. After freezing for a peri

8. Experimental diabetes exacerbates skin transplant rejection in rats
PURPOSE: To investigate the effect of chronic experimental diabetes on skin allografts in rats as a simple model that could clarify some basic aspects and mechanisms involved in transplant rejection in diabetes compared to normal animals. METHODS: Skin grafting was performed with fragments of tail skin from sex matched non diabetic Wistar rats engrafted onto

9. Comparative study and histomorphometric analysis of bone allografts lyophilized and sterilized by autoclaving, gamma irradiation and ethylene oxide in rats
PURPOSE: To compare three sterilization methods (autoclave, gamma irradiation and ethylene oxide) over non demineralized lyophilized bone allografts. METHODS: Bone allografts were implanted on paravertebral muscles of 21 rats. After 30 days animals were sacrificed and grafts underwent comparative analysis regarding histomorphometric and macroscopic parameter

10. Vias efetoras pelas quais a Hsp70 de Mycobacterium tuberculosis inibe a rejeição aguda em um modelo de aloenxerto cutâneo
Transplantation of solid organs has emerged as a viable therapeutic modality for the treatment of a variety of disorders. Rejection of solid organ allografts is the result of a complex range of interactions involving coordination between both the innate and adaptive immune system. Therewith, a major goal of clinical organ transplantation is to induce a donor

11. Efficacy of a combination of simvastatin and poly(DL-lactic-co-glycolic acid) in stimulating the regeneration of Bone Defects
The proper healing of bone defects requires a bone graft or bone substitute and synthetic materials have been developed as alternatives to autografts and allografts. Poly(DL-lactic-co-glycolic acid) (PLGA) is a synthetic polymer widely used for bone healing because of its biocompatibility and biodegradability. PLGA scaffolds have also been used in drug deliv

12. Early outcomes of laparoscopic donor nephrectomy with multiple renal arteries
PURPOSE: We evaluated our experience with laparoscopic donor nephrectomy in patients with multiple renal arteries, comparing operative outcomes and early graft function with patients with a single renal artery. MATERIALS AND METHODS: From January 2003 to February 2009, 130 patients underwent laparoscopic donor nephrectomy at our institution, 108 (83%) with a
