peripherally inserted venous ports fracture with embolization in patients who received chemotherapy is a serious and rare complication,and few cases have been reported in children. we report a successful endovascular technique using a snare for retrieving broken peripherally inserted venous ports in a child for chemotherapy. catheter fragments may cause complications such as cardiac perforation...

Fluidized beds are being used in practice to gasify biomass to create producer gas, a flammable gas that can be used for process heating. However, recent literature has identified the need to better understand and characterize biomass fluidization hydrodynamics, and has motivated the combined experimental-numerical effort in this work. A cylindrical reactor is considered and a side port is intr...

As data communication rates climb toward ten Gbls, clock recovery and synchronization become more dificult, if not impossible, using conventional electronic circuits. We present in this article experimental results of a high speed clock and carrier recovery using a novel device called the photonic oscillator that we recently developed in our laboratory. T h i s device is capable of recovering c...

PURPOSE To report a case of retinal detachment with a macular hole following photodynamic therapy (PDT) using verteporfin and intravitreal bevacizumab injection in the treatment of myopic choroidal neovascularization (CNV). METHODS A 58 -year-old woman was diagnosed with myopic CNV and treated with a combination of PDT with verteporfin and intravitreal bevacizumab injection that same day. She...

evidence acquisition a systematic literature searching of databases medline, embase, and google scholar was done from 1982 and updated in december 2015. search terms were “cholecystectomy”, “laparoscopic cholecystectomy”, “four port laparoscopic cholecystectomy”, “single-incision laparoscopic surgery”. context laparoscopic approach with its several techniques has become the standard method for ...

Access-port (AP) complications after laparoscopic adjustable gastric banding (LAGB) are often seen but seldom reported in literature. AP complications requiring additional surgery is reported in 3.6% to 24% of LAGB patients (Susmallian et al. Obes. Surg, 4:128-131, 2003; Peterli et al. Obes. Surg., 12(6):851-856, 2002; Busetto et al. Obes. Surg., 12:83-92, 2002; Mittermair et al. Obes. Surg., 1...

A port-a-cath was accidentally inserted into an arterial vessel of a 78-year-old woman. Chest X-ray was suggestive for aortic placement (Fig. 1A) being confirmed by computed tomography (Fig. 1B). The patient was immediately scheduled for surgery, which could be performed without cardiopulmonary bypass (Fig. 1C and D). The patient made a swift recovery. Fig. 1. (A) Port-a-cath as shown in the pr...

This paper analyzes the impact of message-ordering, between outgoing messages from a sender to multiple receivers (called multicasts), on the completion time of a program for distributed-memory systems. We study how best to order a set of outgoing messages by taking into account message criticality and architectural issues like multiple injection ports, routing adaptivity, and link contention. ...

The onset of tumour in biological tissues affects their optical properties. In the present study Monte Carlo simulation of the diffuse surface reflectance and transmittance for detection of the inhomogeneities/ tumour in control tissue is carried out. From the isolated heart, spleen and adipose tissues of goat digital phantoms are prepared. The virtual optical probe consists of a photon injecti...

The control of a flexible beam using ionic polymer metal composites (IPMCs) is investigated in this paper. mechanical dynamics are modelled as Timoshenko beam. electric the IPMCs considered model. port-Hamiltonian framework used to propose an interconnected model and IPMC actuator. Furthermore, passive Hamiltonian structure-preserving linear quadratic Gaussian (LQG) controller achieve desired c...
