Donor specific antibodies made easy - Renal Fellow Network
2022年3月12日 · Donor specific Antibodies (DSA) are one of the established biomarkers for predicting antibody mediated rejection (ABMR). This blog is a short synopsis on DSA and their complex characteristics in kidney transplantation. DSA may be preformed (before transplantation) or de-novo (developing after transplantation).
Donor-Specific Antibodies in Kidney Transplant Recipients
Binding of DSA to antigen expressed on allograft endothelial cells can activate classic complement pathway, a key pathologic process of acute antibody-mediated rejection phenotypes (4,11). Even in absence of complement activation, some DSAs can cause graft damage through antibody-dependent cellular cytotoxicity.

DSA在颅脑疾病中的应用 - 知乎 - 知乎专栏
数字减影血管造影 (digital subtraction angiography，DSA)是电子计算机与传统的血管造影相结合的一种新的检查方法，它是在1981年布鲁塞尔国际放射学会上正式推出。 此后世界各大厂商相继展出各种样机。 十余年来，DSA机器种类、减影方式、成像速度、图像质量等方面得到明显的改进和发展。 传统的X线检查是将X线球管产生的X线，穿过被检人体后，其衰减后的X线投射荧光屏或X线片上，从而得到X线图像。 后来有人研制了一种影像增强装置，其输出增益可较普通的荧 …
