Results Following Stent-Graft Coverage of the Hypogastric Artery in the Management of Aortoiliac Aneurysms in Endovascular Aneurysm Repair.

<b><br>Aim:</b> The aim of our study was to assess the outcomes of stent-graft coverage of the hypogastric artery in the management of aortoiliac aneurysms with endovascular aneurysm repair (EVAR).</br> <b><br>Material and methods:</b> From January 2013 to March 2017, a total of 93 patients with aortoiliac aneurysms were treated with EVAR, which required occlusion of one or both of the hypogastric arteries. The patients of the Department of General, Vascular, Endocrine and Transplant Surgery were included in the study continuously and all procedures were elective.

Rapid Formation and Hybrid Treatment of a Large Superior Mesenteric Artery Aneurysm.

BACKGROUND Superior mesenteric artery (SMA) aneurysms account for about 5.5% of all visceral aneurysms, and are most commonly secondary to infectious causes or dissection. They tend to expand and rupture.

Towards More Efficient Rényi Entropy Estimation.

Estimation of Rényi entropy is of fundamental importance to many applications in cryptography, statistical inference, and machine learning. This paper aims to improve the existing estimators with regard to: (a) the sample size, (b) the estimator adaptiveness, and (c) the simplicity of the analyses. The contribution is a novel analysis of the generalized "birthday paradox" collision estimator.

Mutational analysis and glycosylation sensitivity of restrictive XPR1 gammaretrovirus receptors in six mammalian species.

Most viruses infect only a few hosts, but the xenotropic and polytropic mouse leukemia viruses (X/P-MLVs) are broadly infectious in mammalian species. X/P-MLVs use the XPR1 receptor for cell entry, and tropism differences are due to polymorphisms in XPR1 and the viral envelope. To characterize these receptor variants and identify blocks to cross-species transmission, we examined the XPR1 receptors in six mammalian species that restrict different subsets of X/P-MLVs.
