background: anti-hla-antibodies are known to affect the allograft survival in transplant recipient patients. objective: the aim of this study was to evaluate the association between anti-hla antibodies and kidney allograft outcomes, particularly in recipients with concur-rent donor bone marrow cell infusion (dbmi). methods: between june 2006 and may 2007, forty living unrelated donor kidney tra...

background: perioglasâ (pg) is an alloplastic material used for grafting periodontal osseous defects since 1995. in animal models, it has been proven that pg achieves histologically good repair of surgically created defects. in clinical trials, pg was effective as an adjunct to conventional surgery in the treatment of intrabony defects. because the molecular events due to pg that are able to al...

the gamma irradiation has been used for end sterilization of allograft bones and its effects with a 25 kgy dosage on the osteoinductive properties of demineralized bone allograft powder was studied. this work carried out using an experimental method in an animal model. in this study the demineralized bone allograft powder which had been sterilized and prepared with gamma irradiation in a 25 kgy...

BACKGROUND Allograft survival among black recipients is poorer than among whites. Delayed allograft function is associated with a significant reduction in renal allograft survival. The relationship between delayed allograft function and black race is incompletely specified and was the focus of this investigation. METHODS A non-concurrent study of 325 recipients of cadaveric allografts followe...

Background: The Presence of donor leukocytes in recipients of organ allograft has been shown even several years after transplantation. However, it remains unclear whether this donor cell microchimerism plays an effective role in allograft acceptance or is simply a consequence of immunosuppressive conditions in recipients. Objective: To study microchimerism in a group of kidney transplant recipi...

Background: Correlations between bone marrow, heart, kidney, liver, skin and lung transplant rejection or survival with human cytokine gene polymorphisms have been described. There are also reports about the role of cytokines and Tumor Necrosis Factors-Alpha (TNF-α) on corneal transplant in animal models. Further studies are needed to clarify the role of cytokines in corneal allograft rejection...

Despite progress made in tuberculosis control worldwide, the disease burden and treatment outcome of multidrug-resistant tuberculosis (MDR-TB) patients have remained virtually unchanged. In 2016, the World Health Organization released new guidelines for the management of MDR-TB. The guidelines are intended to improve detection rate and treatment outcome for MDR-TB through novel, rapid molecular...

BACKGROUND Obtaining intraoperative cultures of allograft bone just before use in orthopedic procedures is standard practice in many centres; however, the association between positive cultures and subsequent surgical infections is unknown. Our study had 3 goals: to determine the prevalence of positive intraoperative allograft culture and subsequent infection; to determine if, in cases of subseq...
