Considerable interest has been generated for the development of suitable corneal endothelial graft alternatives through cell-tissue engineering, which can potentially alleviate the shortage of corneal transplant material. The advent of less invasive suture-less key-hole surgery options such as Descemet's Stripping Endothelial Keratoplasty (DSEK) and Descemet's Membrane Endothelial Keratoplasty ...
Drusen are extracellular deposits that accumulate below the retinal pigment epithelium on Bruch's membrane and are risk factors for developing age-related macular degeneration (AMD). The progression of AMD might be slowed or halted if the formation of drusen could be modulated. To work toward a molecular understanding of drusen formation, we have developed a method for isolating microgram quant...
OBJECTIVE To evaluate the impact of organ and tissue donation processes on family members of deceased donors and the probability that they would be an organ or tissue donor in the future. METHODS Cross-sectional survey of 69 families of deceased donors of the organ procurement organizations of the Federal University of São Paulo. RESULTS Donors were predominantly men (57% vs 43%) with a med...
OBJECTIVE To evaluate outcomes of limbal allograft transplantation from living-related donors to treat partial limbal deficiency secondary to ocular chemical burns. METHODS Retrospective noncomparative case series comprising 17 patients (17 eyes) with partial limbal deficiency (≤50%) secondary to ocular alkali burns (11 eyes) or acid burns (6 eyes). Recipient eyes were treated by removing the...
results there were 64 women and 936 men in the population under study. the mean ± sd age of the donors was 38 ± 11 years. 80 out of 1000 samples (8%) were found to be positive for hbcab. hbv dna was detected in 50% of hbcab positive specimens. the mean ± sd age of donors without hbv dna was 37.7 ± 10.5 years and for donors with hbv dna was 40.9 ± 11.2 years (p = 0.05). objectives the aim of thi...
Nucleic acid testing (NAT) for HIV, HBV and HCV shortens the time between infection and detection by available testing. A group of experts was selected to develop recommendations for the use of NAT in the HIV/HBV/HCV screening of potential organ donors. The rapid turnaround times needed for donor testing and the risk of death while awaiting transplantation make organ donor screening different f...
1692-P Stress in Beta Cells Obtained with Laser Capture Microdissection from Cadaver Pancreases of Brain Dead Donors AREF EBRAHIMI, MIN-HO JUNG, JONATHAN M. DREYFUSS, HUI PAN, DENNIS C. SGROI, SUSAN BONNER-WEIR, GORDON C. WEIR, Boston, MA Brain death of pancreas donors is thought to lead to the expression of infl ammatory, stress and apoptotic pathways in isolated islets resulting in poor clini...
A new simple method of evaluating specific cytotoxicity to tuberculoprotein in the study of tuberculin hypersensitivity in vitro by comparing cell populations is presented. Utilizing this technic it was possible to reproduce Rich's results (1, 2) using human tissues of reticuloendothelial origin. The demonstration of the specific cytotoxic phenomenon in tuberculin-sensitive human tissues indica...
