Eusocial insects are distinguished by their elaborate cooperative behavior and are sometimes defined as superorganisms. As a nest-bound superorganism, individuals work together to maintain favorable nest conditions. Residing in temperate environments, honey bees (Apis mellifera) work especially hard to maintain brood comb temperature between 32 and 36 °C.(More)
BACKGROUND Patients with juxtarenal aortic aneurysms who are unfit for open repair may be considered for fenestrated endovascular repair (fenEVAR). We report our initial experience with fenEVAR. METHODS We reviewed the data on all our patients receiving fenEVAR for juxtarenal aortic aneurysms. RESULTS Eight patients, average age 75 years, underwent(More)
HYPOTHESIS The antegrade access (AA) for percutaneous arterial interventions is associated with a higher complication rate than is the retrograde access (RA). DESIGN Retrospective case review. SETTING A statewide consortium for peripheral vascular interventions consisting of 13 Michigan hospitals collecting data on their endovascular procedures. (More)
BACKGROUND An increasing number of elderly patients present for elective and emergent vascular procedures. The purpose of this study was to analyze the 30-day and long-term outcome of patients in their 10th decade of life undergoing vascular procedures. METHODS We reviewed the outcomes of all patients in the 10th decade of life included in our registry.(More)
– This paper introduces an XML-based generic Context Request Language (CRL), whose construction is part of a long-term programme to build a web services framework in the domain of mobile context sensing. The paper describes an implementation of the technique that is in accordance with the formal mathematical representational model, using first-order(More)
OBJECTIVE To study the outcomes of three different types of arteriovenous fistula (AVF) transpositions (forearm cephalic vein transposition [FACVT], upper arm cephalic vein transposition [UACVT], and upper arm basilic vein transposition [UABVT]) for dialysis patients in a single center. METHODS A 6-year retrospective review, from 2006 to 2012, was(More)
OBJECTIVE Endothermal heat-induced thrombosis (EHIT) is a known complication of endothermal venous ablation procedures. EHIT can lead to deep vein thrombosis/pulmonary embolism, which cause significant disability and, rarely, death. Other studies have evaluated risk factors for EHIT. There is an accepted grading system for EHIT, but there is no consensus on(More)
BACKGROUND Patients with thoracic aorta injuries (TAI) present a unique challenge. The purpose of this study was to review the outcomes of thoracic endovascular aortic repair (TEVAR) in patients with TAI. METHODS A retrospective chart review of all patients admitted for TEVAR for trauma was performed. RESULTS In a 5-year period, 19 patients (6 women and(More)
Endovascular treatment of aneurysmal disease has become the predominant form of repair for all aneurysms. Some areas continue to pose specific challenges to stay within the general tenets of successful repair, mainly achieving adequate seal without sacrificing other arterial pathways. Following aortic aneurysm repair, the common iliac arteries can continue(More)
