Although donor-specific anti-human leukocyte antigen (HLA) antibodies (DSAs) are frequently found in recipients after lung transplantation (LT), the characteristics of DSA which influence antibody-mediated rejection (AMR) in LT are not fully defined. We retrospectively analyzed 206 consecutive LT patients of our center (2010-2013). DSAs were detected by using luminex single antigen beads assay ...
BACKGROUND AND PURPOSE Clinical trials have shown that carotid endarterectomy reduces stroke risk in symptomatic individuals with severe internal carotid artery (ICA) stenosis. As a result of these trials, digital subtraction angiography (DSA) became a standard of reference for ICA stenosis diagnosis. Newer 3D techniques provide a larger number of views than DSA, which may influence the estimat...
This paper proposes an adaptive microphone array using blind deconvolution. The method realizes an signal enhancement based on the combination with beamforming using blind deconvolution, synchronized summation and DSA method. The proposed method improves a performance of estimation by the iterative operation of blind deconvolution using a cost-function base on the coherency function.
Introduction: Stent-treatment is a common option for carotid atherosclerosis patients, and the level of carotid stenosis, typically measured by digital subtraction angiography [DSA]), is the standard criteria to decide on stenting. There are, however, many patients who suffer repeated cerebral ischemia due to carotid atherosclerosis although their level of stenosis excludes them from stenting. ...
This study aimed to compare the clinical value of carotid ultrasound and digital subtraction angiography (DSA) for artery stenosis in patients with cerebral infarction. Sixty infarction underwent DSA. Carotid stenosis, degree (mild, moderate, severe, occlusion), plaques were recorded compared. rate was 96.67 % (58/60) 91.67 (55/60) on DSA ultrasound, respectively, difference not statistically s...
Ti/SnO2-Sb electrode, which is one of the dimensionally stable anode (DSA) electrodes, offers high specific conductivity, excellent electrocatalytic performance, and great chemical stability. For these reasons, electrode has been extensively studied in fields wastewater treatment. This review covers essential research work about advanced oxidation technology related DSA electrodes. It gives an ...
Affymetrix Human Gene 1.0-ST arrays were used to assess the gene expression profiles of kidney transplant patients who presented with donor-specific antibodies (DSAs) but showed normal biopsy histopathology and did not develop antibody-mediated rejection (AMR). Biopsy and whole-blood profiles for these DSA-positive, AMR-negative (DSA +/AMR-) patients were compared to both DSA-positive, AMR-posi...
Dynamic Spectrum Access (DSA) network is envisioned as a promising candidate to significantly improve the spectrum utilization. Due to its specific features of the DSA, however, this network is more vulnerable to security attacks than the traditional wireless networks. And channel jamming is a one of main threats to DSA networks. So far, limited works have been done in mathematical and formal m...
In this paper, we consider multi-stage stochastic optimization problems with convex objectives and conic constraints at each stage. We present a new stochastic first-order method, namely the dynamic stochastic approximation (DSA) algorithm, for solving these types of stochastic optimization problems. We show that DSA can achieve an optimal O(1/ǫ4) rate of convergence in terms of the total numbe...
PURPOSE OF REVIEW To summarize the evidence concerning human leukocyte antigen (HLA) epitope mismatch analysis as a means to predict donor-specific antibody (DSA) development and allograft survival. RECENT FINDINGS HLA epitope mismatch analysis outperforms traditional whole molecule antigen mismatch for predicting the risk of de-novo DSA development. By analyzing the number of epitope mismatc...
