RA-PTAS using DEP resulted in 4- to 6-week postintervention renal function results approximating those of surgical revascularization. These data suggest that DEP use may prevent renal function harm during RA-PTAS as a result of atheroembolism and warrant further investigation.

Adaptor proteins have important functions in coupling stimulation through immunoreceptors with downstream events. The adaptor linker for activation of B cells (LAB)/non-T cell activation linker (NTAL) is expressed in various immune cell types and has a similar domain structure as linker for activation of T cells (LAT). In this study we generated a LAB transgenic mouse to compare the functional differences between LAB and LAT. A LAB transgene expressed in LAT-deficient T cells was able to restore T cell development. However, these mice developed severe organomegaly with disorganized lymphoid tissues. Lymphocytes from these transgenic mice were hyperactivated, and T cells produced large amounts of type II cytokines. In addition, these activities appeared to be uncoupled from the TCR. An examination of the signaling capabilities of these T cells revealed that LAB resembled a LAT molecule unable to bind phospholipase C-γ1.

This is the first prospective, population-based estimate of incident RVD and progression of prevalent RVD among free-living elderly Americans. In contrast to previous reports among select hypertensive patients, CHS participants with a low rate of clinical hypertension demonstrated a significant change of RVD in only 14.0% of kidneys on follow-up of 8 years (annualized rate, 1.3% per year). Progression to significant RVD was observed in only 4.0% (annualized rate, 0.5% per year), and no prevalent RVD progressed to occlusion.

In our experience, both P-VCF and R-VCF can be placed safely. Among both permanent and retrievable devices, however, opposed biconical designs seem to be associated with an increased risk for vena cava thrombosis. Although causative factors remain unclear, filter design and resultant flow dynamics may play an important role, because all episodes of vena cava thrombosis occurred in patients with a single-filter design.
