background in the living donor liver transplant setting, the preoperative assessment of potential donors is important to ensure the donor safety. objectives the aim of this study was to identify causes and costs of living liver-donors rejection in the donation process. materials and methods from june 2010 to june 2012, all potential living liver donors for 66 liver transplant candidates were sc...

stem cell research has obtained much prominence in recent years for its therapeutic potential in dealing with serious diseases, many of which are essentially incurable by routine therapies. mesenchymal stem cells with pluripotency and immunomodulatory properties are suitable candidates for tissue engineering and regenerative medicine. today, nanofibrous scaffolds are widely used in tissue engin...

human adipose tissue represents an abundant, practical and appealing source of donor tissue for autologous cell replacement. recent findings have shown that stem cells within the stromalvascular fraction of adipose tissue display a multilineage developmental potential. adipose tissue-derived stem cells can be differentiated towards adipogenic, osteogenic, chondrogenic,myogenic and neurogenic li...

AMONG THE PROBLEMS presented by the chronic uraemie patient, the anaesthetist is particularly concerned with anaemia, a-3 acid-base and electrolyte upsets, and impaired renal excretion of drugs. When such patients are on chronic haemodialysis programs, they frequently present for surgical creation or revision of arteriovenous shunts and fistulae. Usually, these procedures are done under local o...

A simple and sensitive spectrophotometric assay for quaternary ammonium compounds (QACs) based on Dragendorff's reagent is described. Although not specific for a particular QAC, the assay allows for rapid survey of tissue for QAC content. A separation method for QACs in halophyte tissue containing high levels of cations was developed using ion exchange resins and ninhydrin to remove the amino a...

D. Carasso, G. Navon School of Chemistry, Tel Aviv University, Tel Aviv, Israel Introduction An image with a good contrast between coagulated and non-coagulated tissue can assist in improving the accuracy and the reliability of thermal ablation of tumors and of uterine fibroids. As was recently reported (1), the rate of magnetization exchange between macromolecules and water in the tissue depen...

The objective of the present study is to evaluate the pharmacodynamic properties of polymerized porcine hemoglobin (pPolyHb) in an exchange transfusion model. Each of two groups of rats received a volume of pPolyHb or hetastarch that equalled 120-140% of estimated total blood volume (70 ml/kg) exchange transfusion. The results showed pPolyHb retained hemodynamic stability and exhibited superior...

Gas exchange occurs in the alveolus where the thin laminar blood flow and inspired air are separated only by a thin tissue layer. Gas exchange takes 0.25 seconds or 1/3 of the total transit time of a red cell. The entire blood volume of the body passes through the lungs each minute in the resting state, that is 5 liters per minute. The total surface area of the lung is about 80 meters square, e...

severe hepatic failure accounts for many deaths and raises medical costs each year worldwide. currently, liver transplantation is the most common therapeutic option for patients with end-stage chronic liver disease. due to decrease in the number of organ donors, many in need of transplantation continue to remain on the waiting list. hepatic tissue engineering is a step toward alleviating the ne...
