2. Chronic Obstructive Pulmonary Disease: The Role of Myocardial Deformation Indices and Right Ventricle Three-Dimensional Echocardiography
Abstract Background: Right ventricular dysfunction is a major complication in chronic obstructive pulmonary disease (COPD) and, despite its prognostic implications, is rarely considered in routine clinical analysis. Objectives: To compare RV function variables with standard and advanced echocardiographic techniques in patients with stable COPD and controls

4. Three-dimensional reconstruction and intraoperative ultrasonography: Crucial tools to safely approach highly complex renal masses
ABSTRACT Purpose: Robot-assisted partial nephrectomy (RAPN) is rapidly increasing its role in the nephron-sparing surgery setting (1). The recent introduction of technological advancements is leading more experienced surgeons to approach complex renal mass with a conservative intent (2, 3). In particular, three-dimensional reconstruction and the use of intr

8. Three-Dimensional Printing: is it useful for Cardiac Surgery?
Abstract Introduction: The medical use of three-dimensional (3-D) images has been a topic in the literature since 1988, but 95% of papers on 3-D printing were published in the last six years. The increase in publications is the result of advances in 3-D printing methods, as well as of the increasing availability of these machines in different hospitals. Thi

9. Risk Factors for Mortality in Pediatric Cardiac Intensive Care Unit
The present study investigated the activity of pyrimidine derivatives against Aedes aegypti. Two compounds, 3c and 3d showed excellent larvicide activity. Additionally, quantitative structure-activity relationship (QSAR) models were built using multiple-linear regression and partial least squares with descriptors generated from Dragon and VolSurf+ software,

11. Multistage Phase Decomposition Behavior and Kinetics for Zr65Ni30Pd5 Ternary Amorphous Alloy
We have examined heating-induced phase decomposition and its kinetics for Zr65Ni30Pd5 amorphous alloy in an argon atmosphere. The amorphous phase decomposes through three stages in the order of amorphous → icosahedral quasicrystal (I-Q) + amorphous → approximant cubic Zr2(Ni,Pd) → tetragonal Zr2Ni + tetragonal Zr2Pd phases. The approximant crystalline
