Purpose: Despite convergent evidence indicating a wide range of advantages for computed tomography angiography (CTA) for evaluating vascular anatomy prior to laparoscopic complete mesocolic excision (CME), the operative effects of CTA remain to be determined. In this study, we investigated alterations in operative outcomes caused by preoperative CTA. Methods: Based on CTA, arterial and venous v...

BACKGROUND AND PURPOSE Reversed shoulder arthroplasty may be used for severe arthropathy where conventional prostheses cannot restore the function sufficiently. We analyzed the medium-term results and potential complications of the reversed prostheses, and also the influence of etiology on the result. METHODS; 52 women and 7 men, average age 70 (60-82) years, were followed for mean 4 (2-7) year...

The prospective study included 54 asymptomatic high-risk patients who underwent coronary CT angiography (CTA) and regadenoson-induced stress CT perfusion (rsCTP). Diagnostic accuracy of significant stenosis (≥50%) determination was evaluated for CTA alone and CTA + rsCTP in 27 patients referred to ICA due to the positive rsCTP findings. Combined evaluation of CTA + rsCTP had higher diagnostic a...

In their recent topical review, Nabavi and Siddiqui (Meas. Sci. Technol. 2010 21 042002) recommended the use of hot-wire anemometry for velocity measurements in pulsating flows, especially at high frequency. This recommendation is misleading. The procedures invoked by these authors are valid only for small-amplitude fluctuations, which are of little interest for pulsating flows. When large-ampl...

UNLABELLED Sequential testing by coronary CT angiography (CTA) and myocardial perfusion SPECT (MPS) obtained on stand-alone scanners may be needed to diagnose coronary artery disease in equivocal cases. We have developed an automated technique for MPS-CTA registration and demonstrate its utility for improved MPS quantification by guiding the coregistered physiologic (MPS) with anatomic CTA info...

We report a room-temperature photoinitiated polymerization-induced self-assembly (photo-PISA) of 2hydroxypropyl methacrylate (HPMA) in the presence of silica nanoparticles using a poly(ethylene glycol) methyl ether (mPEG) macromolecular chain transfer agent (macro-CTA). Hybrid vesicles loaded with silica nanoparticles were obtained by this one-pot approach. The solids content of the polymer ves...
