Background: Monitoring of phenotypic characteristics of T-lymphocytes in peripheral blood is commonly performed to give the clinical parameters in the management of kidney transplant recipients.   Objective: To predict rejection in renal transplantation by immune parameters. Methods: 16 non-diabetic kidney transplant candidates (4 females and 12 males, age = 20-65 yr, first time transplant) wer...

Random coe cient regression models have been applied in di erent elds and they constitute a unifying setup for many statistical problems. The nonparametric study of this model started with Beran and Hall (1992) and it has become a fruitful framework. In this paper we propose and study statistics for testing a basic hypothesis concerning this model: the constancy of coe cients. The asymptotic be...

A novel voltage reference has been proposed and simulated using a 0.18μm CMOS process in this paper. A near-zero temperature coefficient voltage is achieved in virtue of the bias voltage subcirciut which consists of two MOSFETs operating in the saturation region. The kind of bias voltage subcirciut is used to adjust the output voltage and compensate the curvature. The output voltage is equal to...

early wound excision and grafting of burn wounds is regarded not only as the method of choice in speeding up the healing process in deep burns, but also limits contracture and infection, on the other hand, smoking has generally been implicated in the delay of the healing process in a variety of surgical procedures, in this study we report the outcome of a cross-sectional study of all the 395 me...

corneal transplantation is the most common and successful form of solid organ transplantation with a 2-year survival rate of over 90% in low risk cases. this high success rate may be due to the immune privileged status of the cornea, acaid (anterior chamber associated immune deviation) induction phenomena and secretion of inhibitory molecules by corneal cells such as il1-ra, il-1a and fas ligan...

cyclosporine (csa) is a drug that has been used for prevention of kidney transplant rejection for many years. diltiazem with the inhibition of cyclosporine metabolism and clearance will increase csa concentration and csa dose can be decreased. the aim of this study was the evaluation of diltiazem effect on csa dose adjustment with respect to c2. forty stable renal transplant patients who were r...

background: kidney transplantation is the best alternative treatment for end-stage renal disease. several studies have been devoted to investigate predisposing factors of graft rejection. however, there is inconsistency between the results. the objective of the present study was to utilize an intuitive and robust approach for variable selection, random survival forests (rsf), and to identify im...

results afscs have the potential to be used in tissue repair and regeneration of bladder and kidney injuries, for the treatment of congenital anomalies like tracheal anomalies and spina bifida therapy etc. however, like other treatment, afscs also have some limitations such as low rate of differentiation of transplanted afscs and immune rejection. conclusions afscs have great therapeutic potent...

in this paper, the effect of transmembarne pressure (tmp) at levels of 1, 1.75 & 2.5 bar, process temperature (t) at levels of 30 & 60oc and operation time (t) at levels of 15, 30, 45 & 60 minute on the permeate flux, sugar rejection, non-sugar rejection and fouling as membrane performance indexes investigated. membrane system used in this research was ceramic tubular module and it had effectiv...

background: thymoglobuline (tg), is used for both induction and rejection therapy in kidney transplantation (tx). this study was conducted to compare between adding tg or not to the conventional drugs to evaluate the rate of rejections, infections and costs. methods: in two groups of patients, each of 45 cases group a received conventional drugs (cyclosporine, mycophenolate and prednisolone) an...
