in this work, several machine learning techniques are presented for nanofiltration modeling. according to the results, specific errors are defined. the rejection due to nanofiltration increases with pressure but decreases with increasing the concentration of chloride ion. methods of machine learning represent the rejection of nanofiltration as a function of concentration, ph, pressure and also ...

background: the innate immunity plays an important role in the host response to transplantation by toll-like receptors and results in development of acute allograft rejection. the aim of this study was to evaluate the association of tlr2 and cd14 (co-receptor) gene polymorphisms with acute rejection in kidney transplant recipients.   methods : the study was conducted in a population of 239 subj...

Abstract In this paper, a miniaturized size UWB 4-element MIMO antenna with band rejection feature is introduced. The four elements have rectangular radiator curved edges and partial ground plane an etched slot to enlarge the bandwidth of suggested structure operate from 3 up 12 GHz S 11 ≤ − 10 dB. high isolation between was achieved by forming antennas orthogonally without adding decoupling si...

background: human cornea expresses functional fas-ligand capable of killing fas+ activated lymphocytes. fas expression is partly regulated by -670 a/g polymorphism in the promoter region of fas gene. objective: the aim of the present study is to determine the association between fas-670a/g polymorphism and survival of corneal transplantation. methods: in 276 graft recipients who mainly underwen...

The main objectives of this study were to remove surface-active agents and to predict the adsorption rejection models.  The effects of surfactant concentration and PAC amount on the adsorption were determined. For both surfactants, It was found that the adsorption values also increased when PAC amount increased. It was observed that the rejection values are different for the adsorption of C...

This article describes a method of isolating high-resolution digitizers that have common ground between channels. Isolation enables the to be used simultaneously measure multiple points in circuit without short-circuiting via ground. The isolators, when switch formation, provide cancel out phase angle errors measuring difference angles Various tests are reported, which assess performance isolat...

for monitoring of renal transplant function, serum b2m was evaluated in 23 recipients. according to clinical diagnosis the patients were in four groups: 1) successful renal transplant the mean concentration of sb2m pretransplantation was 73.1±26.1 mg/l but decreased to nearly normal level (4.43±1.17 mg/l) within 24-48h and then reached to 3.1 mg/l duting 20 days after transplantation. 2) renal ...

introduction: acute rejection of renal transplant is a serious and common systemic inflammatory disorder which leads to decreasing half-life of transplant organ. current diagnoses method is an invasive biopsy procedure on allogtraft kidney. therefore, applying a novel and noninvasive diagnostic method such as granzym b level in acute renal transplantation could help patients and improves surviv...
