OBJECTIVE We evaluated the effect of endovascular treatment (EVT) for acute ischemic stroke in patients over 80 years of age. MATERIALS AND METHODS The records of 156 acute stroke patients aged over 80 years who were considered as candidates for EVT were analyzed. Fifty-six patients (35.9%, EVT group) underwent EVT and 100 patients (64.1%, non-EVT group) did not. Outcomes, in terms of functio...
BACKGROUND AND PURPOSE It is often thought that elderly patients in particular would benefit from endovascular aneurysm treatment. The aim of this analysis was therefore to compare the efficacy and safety of endovascular coiling (EVT) with neurosurgical clipping (NST) in the subgroup of elderly SAH patients in the International Subarachnoid Aneurysm Trial (ISAT). METHODS In the ISAT cohort 27...
Heat shock protein (HSP27) is expressed in human placentae. Previously, we showed that HSP27 is expressed in the villous cell column of first trimester placental explants and in extravillous trophoblast (EVT) cells. EVT differentiation is accompanied by increased motility, matrix metalloproteinase (MMP) activity, decreased proliferation and expression of specific markers such as HLAG and CD9. H...
BACKGROUND Vascular smooth muscle cells (VSMCs) migration is a critical process during human uterine spiral artery (SpA) remodeling and a successful pregnancy. Extravillous trophoblast cells (EVT) interact with VSMC and enhance their migration, however, the mechanisms by which EVT remodel SpA remain to be fully elucidated. We hypothesize that exosomes released from EVT promote VSMC migration. ...
BACKGROUND AND PURPOSE Standard operating procedures (SOP) incorporating plasma levels of rivaroxaban might be helpful in selecting patients with acute ischemic stroke taking rivaroxaban suitable for IVthrombolysis (IVT) or endovascular treatment (EVT). METHODS This was a single-center explorative analysis using data from the Novel-Oral-Anticoagulants-in-Stroke-Patients-registry (clinicaltria...
In this paper we discuss the limitations of and the precautions to account for when using Extreme Value Theory (EVT) to compute upper bounds to the execution time of programs. We analyse the requirements placed by EVT on the observations to be made of the events of interest, and the conditions that render safe the computations of execution time upper bounds. We also study the requirements that ...
BACKGROUND Uterine natural killer (uNK) cells are a major source of cytokines and angiogenic growth factors (AGFs), with AGF levels decreasing and cytokine levels increasing with gestational age. The factors that regulate AGF and cytokine secretion are unclear but may involve interactions between uNK cells and extravillous trophoblast (EVT) cells. We hypothesize that uNK cell interaction with E...
This paper introduces a conditional extreme value volatility estimator (EVT) based on highfrequency returns. The relative performance of the EVT is compared with the discrete-time GARCH and implied volatility models for 1-day and 20-day-ahead forecasts of realized volatility. This is also a first attempt towards detecting any time-series variation in extreme value distributions using high-frequ...
BACKGROUND It is unclear whether 16-detector row CT angiography (CTA) can replace digital subtraction angiography (DSA) to assess the feasibility of endovascular treatment (EVT) in the acute phase after aneurysmal subarachnoid hemorrhage. METHODS We studied 80 consecutive patients with aneurysmal subarachnoid hemorrhage, who underwent both CTA and DSA. Two interventional neuroradiologists ind...
OBJECTIVE This study was designed to investigate our long-term experience with combined iliac endovascular therapy (EVT) and infrainguinal bypass to treat critical limb ischemia (CLI) and compare outcomes to those of patients who underwent surgery for aortoiliac lesions. MATERIALS AND METHODS From April 2000 to June 2013, 57 patients (58 limbs) underwent an infrainguinal bypass combined with ...
