BACKGROUND: Angioplasty on the radial artery have been performed with good success rates in patients with critical hand ischemia. We sought to assess the feasibility and safety of radial angioplasty on complex radial access in patients undergoing coronary angiography. METHODS/MATERIAL: A prospective series of procedures with complex radial/ulnar access to which radial-ulnar angioplasty (RU-A) was performed. We set goals of efficacy and safety that included the success rate of the procedure (need for ¨Crossover femoral¨) and the existence of radial pulse at one month...

The detailed structure of singularities of ordered field represents a fundamental problem in diverse areas of physics. At the defect cores, the deformations are so strong that the system explores states with symmetry different from that of an undistorted material. These regions are difficult to explore experimentally as their spatial extension is very small, a few molecular lengths in the condensed matter. Here we explore the cores of disclinations in the so-called chromonic nematics that extend over macroscopic length scales accessible for optical characterization...

The radial approach to endovascular procedures has a series of learning curves: diagnostic heart catheterization, low-risk settings and "straightforward" percutaneous coronary intervention, high-risk settings, and complex coronary intervention, and peripheral vascular angiography and intervention. For diagnostic and low-risk interventional procedures, incremental improvements in technical success and safety are observed in the initial 200 procedures for most operators compared to highly experienced operators...

In the last decades, the field of structural health monitoring and damage detection has been intensively explored. Active vibration techniques allow to excite structures at high frequency vibrations which are sensitive to small damage. Piezoelectric PZT transducers are perfect candidates for such testing due to their small size, low cost and large bandwidth. Current ultrasonic systems are based on external piezoelectric transducers which need to be placed on two faces of the concrete specimen. The limited accessibility of in-service structures makes such an arrangement often impractical...

The goal of this study was to describe an internal fixation technique for periprosthetic humeral fractures using a cortical onlay strut allograft stabilized with cerclage wires and to evaluate the preliminary results of this approach. An anterolateral approach was used to direct access the fracture and to protect the radial nerve. The fracture was reduced with two forceps, under visual control. The fracture was surrounded by two hemicylinder tibial allografts, placed around the humerus with no prior reaming to create a "sarcophagus" system...

We compared the clinical outcomes of patients who underwent coronary artery intervention by the transulnar and transradial artery approaches. In this 1 year, single-center study, patients were randomized to either a radial artery (RA) or ulnar artery (UA) group. Of 538 patients, the primary outcome, arterial occlusion of a forearm artery, occurred in 21 of 225 patients in the RA group compared to 6 of 220 patients in the UA group (9.3% vs 2.7%, P = .007). The rate of arterial occlusion was significantly lower following ulnar access compared to radial (odds ratio [OR] = 3...

Same-day discharge after combined percutaneous carotid and coronary stenting in a single session has not been previously reported. Using a transradial approach, we completed both procedures successfully and the 63-year-old patient was discharged home after a few hours. This case illustrates that radial access allows treatment of complex coronary and peripheral lesions in a same setting and could provide clinical and cost benefits if safety is confirmed.

The left ventricular ejection time is routinely measured from a peripheral arterial waveform. However, the arterial waveform undergoes constant transformation as the pulse wave propagates along the arterial tree. Our goal was to determine if the left ventricular ejection time measured peripherally in the arterial tree accurately reflected the ejection time measured through the aortic valve. Moreover, we examined/accessed the modulating influence of hemodynamics on ejection time measurements. Continuous wave Doppler waveform images through the aortic valve and the simultaneously obtained radial artery pressure waveforms were analyzed to determine central and peripheral ejection times, respectively...

Resveratrol (RES) is a kind of polyphenolic compounds discovered from grapes and has become a prominence as a possible contributor to many diseases treatments. Herein, three different types of liposomes were prepared as model cell membranes, and then the influence of the incorporation of RES on their membrane properties was evaluated by utilizing the membrane-binding fluorescent probes. The binding of RES lead the membrane polarities decreased slightly, regardless of the phase states of membrane. While the membrane fluidities decreased only in the case of liquid-disordered phase...
