RAP MUSIC AND HEGEMONY: A HISTORICAL ANALYSIS OF RAP'S NARRATIVES Jamar Montez Wheeler

Renal artery pseudoaneurysm (RAP) is a rare complication of partial nephrectomy, but is usually effectively managed with renal vessel embolisation. We report a particularly challenging case of a patient with chronic kidney disease (CKD) who developed a RAP following a laparoscopic heminephrectomy and was treated using superselective renal vessel coil embolisation with carbon dioxide (CO2) as th...

The large family of Gram-positive quorum-sensing receptors known as the RNPP proteins consists of receptors homologous to the Rap, NprR, PlcR, and PrgX proteins that are regulated by imported oligopeptide autoinducers. Rap proteins are phosphatases and transcriptional anti-activators, and NprR, PlcR, and PrgX proteins are DNA binding transcription factors. Despite their obvious importance, the ...

BACKGROUND Free light chains (LCs) are among the many ligands that bind to cubilin/megalin for endocytosis via the clathrin-dependent endosomal/lysosomal pathway. Receptor associated protein (RAP), is a 39 kDA high-affinity, chaperone-like ligand for megalin that assists in the proper folding and functioning of megalin/cubilin. Although RAP is known to inhibit ligand binding to megalin/cubilin,...

BACKGROUND Although right atrial pressure (RAP) and pulmonary capillary wedge pressure (PCWP) are correlated in heart failure, in a sizeable minority of patients, the RAP and PCWP are not tightly coupled. The basis of this variability in the RAP/PCWP ratio, and whether it conveys prognostic value, is not known. METHODS AND RESULTS We analyzed the Evaluation Study of Congestive Heart Failure a...

Signaling by the B cell antigen receptor (BCR) activates the Rap1 and Rap2 GTPases, putative antagonists of Ras-mediated signaling. Because Ras can activate the Raf-1/ERK pathway and the phosphatidylinositol 3-kinase (PI3K)/Akt pathway, we asked whether Rap activation limits the ability of the BCR to signal via these pathways. To do this, we blocked the activation of endogenous Rap1 and Rap2 by...

The Rap G protein signal regulates Notch activation in early thymic progenitor cells, and deregulated Rap activation (Rap(high)) results in the development of Notch-dependent T-cell acute lymphoblastic leukemia (T-ALL). We demonstrate that the Rap signal is required for the proliferation and leukemogenesis of established Notch-dependent T-ALL cell lines. Attenuation of the Rap signal by the exp...

The overwhelming majority of multimedia streaming applications in today’s Internet employ UDP as their transport layer protocol. However, UDP is quite primitive with only a simple checksum for error detection, but no error recovery and traffic control. UDP flows disregard the fair competition with TCP traffic and probe for more network bandwidth as possible as they can. Extensive deployment of ...

Retinal Arterial Pressure Before and After Surgery for Carotid Artery Stenosis • This is a study of 45 patients who underwent angiography and surgery of one or both carotid arteries (56 surgical procedures). All patients had detailed neuro-ophthalmological evaluations including determination of retinal artery pressure (RAP) and scrutiny for emboli in small vessels. Preoperatively, the absolute ...
