Children and their parents in residences are often protected by insecticides from nuisance and disease-bearing mosquitoes. The annual worldwide consumption of the four major types of residential insecticide products--aerosols, mosquito coils, liquid vaporizers, and vaporizing mats--is in the billions of units. Mosquito coils are burned indoors and outdoors in East Asia and to a limited extent i...

PURPOSE To compare the efficacy and biocompatability of electrolytic and mechanically detachable embolization coils of two metal types. METHODS Experimental saccular aneurysms in pigs were used to assess embolization induced by platinum or tungsten coils. Longitudinal angiographic and histologic studies were performed on treated and untreated (control) aneurysms to compare thrombosis and cell...

A wireless power transfer system via magnetic resonance has been reported by several groups [1-3]. In those reports, two resonance coils work as a transmission coil and a reception coil, respectively. The transfer efficiency between two coils is a function of the distance and the orientation between the coils. When the distance between the two coils is long, the transfer efficiency is small. Wh...

The scleral search coil technique is commonly used for recording eye movements. The goal of this paper is to investigate to what extent the placement of scleral search coils onto the eyes influences the kinematics of saccades. To that end saccadic eye movements of human subjects were recorded with an infrared video system, while they wore coils and we compared the main sequence properties with ...

Introduction: Essure® device malposition is a rare, but clinically significant complication, for which management is idiosyncratic. This case report describes an unusual example of Essure® migration in order to clarify reasonable management options. Case Presentation: A 50-year old G4P2022 underwent hysteroscopi...

BACKGROUND AND PURPOSE This study arose from a need to systematically evaluate the clinical and angiographic outcomes of intracranial aneurysms treated with modified coils. We report the procedural safety and clinical outcomes in a prospective randomized controlled trial of endovascular coiling for ruptured and unruptured intracranial aneurysms, comparing polymer-loaded Cerecyte coils with bare...

Coiled coils is an important 3-D protein structure with two or more stranded alpha-helical motif wounded around to form a “knobs-into-holes” structure. In this paper we propose an SVM classification approach to predict the antiparallel coiled coils structure based on the primary amino acid sequence. The training dataset for the machine learning are collected from SOCKET database which is a SOCK...

BACKGROUND AND PURPOSE Endovascular treatment of intracranial aneurysms is too often associated with aneurysm recurrence due to coil compaction. High packing of coils prevents compaction. To increase the packing attenuation, we sought to evaluate the results of selective embolization of aneurysms with complex-shaped coils alone. METHODS Twenty consecutive patients with an intracranial aneurys...
