The most recent taxonomic revision in Trichinella genus included 10 taxa. Trichinella spiralis (Ts) is a thoroughly studied species but most of the isolates came from the Europe or American continents. Few information is available from China about the Trichinella isolates and their diversity. In this report two Chinese isolates were characterized and(More)
We report 2 cases of familial multiple endocrine neoplasia type 1 syndrome (MEN 1) in related Malaysian Chinese individuals: the son had simultaneous primary lesions in the pancreatic tail, parathyroid, adrenal gland, and hypophysis, with metastatic tumors in the left lung, mediastinum and spine; his mother had simultaneous primary lesions in the pancreatic(More)
The purpose of this study was to compare a dual-freeze protocol with a triple-freeze protocol for pulmonary cryoablation in a porcine lung model. Five dual- (10-5-10-5) and five triple-freeze (5-5-5-5-10-5) cryoablations were performed on an exposed operation field in normal porcine lung. Changes in the temperature of the cryoprobes and the diameter of the(More)
The purpose of this study was to compare a dual-freeze protocol with a triple-freeze protocol for hepatic cryoablation in a porcine model. Eighteen cryoablations were performed over an exposed operation field in nine normal porcine livers, using dual- (10-5-10-5) and triple-freeze (5-5-5-5-10-5) protocols. Changes in the temperature of the cryoprobes and(More)
A scheme for positioning swimmers using underwater acoustic networks is proposed. The design and the performance of such a network are presented. Owing to its high accuracy, the spherical interpolation approach is employed as the positioning algorithm. The configuration of the network, namely, the arrangement of anchor nodes in the swimming pool, is(More)
In this paper, a methodology of employing a set of uniform circular arrays to localize the 3D position of a target in sensor networks is presented and the theoretical framework is given. Simulation results demonstrate the validity of the method and illustrate the effect of the element pattern on the accuracy of direction of arrival (DoA) estimation and(More)
• Cryosurgery is an old as well as new technique, and has gone through a long-term process of development. The history of " modern " cryosurgery is relatively short and is closely intertwined with developments in low-temperature physics, engineering, and instru-mentation that were made during the last century. • The cryosurgical probes developed in the(More)
A novel wireless positioning method employing an array of sensors which are capable of doing range estimates is proposed. Collectively, all the sensors in the sensor array can produce the direction of arrival (DoA) and the range information of mobile targets. To improve the positioning accuracy, it is proposed to introduce co-operations between the sensor(More)
