Introduction Electrical pulmonary vein (PV) isolation is an effective technique that is used to treat patients with paroxysmal atrial fibrillation (AF). In recent years, PV isolation by cryothermal balloon (CB) ablation has been increasingly adopted by electrophysiology laboratories around the world. This technology is associated with more reproducible results and reduced procedural times and m...

PCR-based methods for the analysis of genomic DNA are becoming increasingly common both in research and for routine purposes. A rapid, small-scale DNA isolation method is needed to take full advantage of the speed and automation potential of the PCR technology. We demonstrate the use of Dynabeads DNA DIRECT, a kit for the isolation of PCR-ready genomic DNA from whole blood, bone marrow or cultu...

We describe a method for the specific isolation of representative N-terminal peptides of proteins and their proteolytic fragments. Their isolation is based on a gel-free, peptide-centric proteomics approach using the principle of diagonal chromatography. We will indicate that the introduction of an altered chemical property to internal peptides holding a free alpha-N-terminus results in altered...

Received: December 19, 2016 Revised: February 06, 2017 Accepted: March 20, 2017 Abstract: Introduction: Seismic isolation has been proven to be an efficient approach to seismic retrofitting of structures based on the concept of reducing the seismic forces by lengthening the structural fundamental vibration period. However, superstructures may collide with each other under seismic excitation as ...

An ultra-deep (40–120 μm) keyhole-free electrical isolation trench with an aspect ratio of more than 20:1 has been fabricated. The process combines DRIE (deep reactive ion etch), LPCVD insulating materials refilling and TMAH or KOH backside etching technologies. Employing multi-step DRIE with optimized etching conditions and a sacrificial polysilicon layer, the keyholes in trenches are prevente...

Radiofrequency ablation (RFA) aiming at the electrical isolation of the pulmonary vein (PV) is more effective in controlling the rhythm than drugs, especially in young individuals with symptomatic paroxysmal atrial fibrillation (AF) without structural heart disease.1-3 Electrical isolation is performed with point-by-point RFA around the PV, constituting a complex and lengthy procedure.2,3 Recen...

In view of the development for TD-SCDMA communication system and combine with the miniaturization technology of smart antenna, by using balun feeding structure and consist of splitters and neural networks, this paper proposed a four units of dual polarized and a eight units of +45/-45 polarized antenna array which on the basis of printed dipole antenna. The simulation results show that the isol...

BACKGROUND/AIM This qualitative study formed part of a large-scale, multi-phase study into the delivery of therapy services to people with a disability, living in one rural area of New South Wales, Australia. The study's purpose was to identify the impact of Information and Communication Technology on the workforce practices of occupational therapists' working in a rural area of New South Wales...

The InAlAs/InGaAs metamorphic HEMT (mHEMT) two-stage Ka-band amplifier and DC-30 GHz distributed SPST switch were designed and fabricated using low-k benzocyclobutene (BCB) bridged technology. This fabrication technology takes the advantages of its low dielectric permittivity (2.7), low loss tangent (0.008), low curing temperature, low water up-take, and simple manufacturing process. The MMIC f...
