Ultrasound Measurements, Physico‐Chemical Characterization and Biological Evaluation of Magnesium Hydroxyapatite for Biomedical Applications

Macromolecular Symposia, EarlyView.
ABSTRACT In this study, 15MgHAp (xMg = 0.15) was synthesized by an adapted method, lyophilized, and characterized to evaluate its physicochemical and biological properties. The ultrasound measurements (US) evaluated the stability of the resulting MgHAp gel. Complementary surface information was obtained using a scanning ultrasonic microscope (SUM). The

Ultrasound Evaluation and Biological Assessment of Zinc‐Doped Hydroxyapatite for Antimicrobial Applications

Macromolecular Symposia, EarlyView.
ABSTRACT In this study, undoped and zinc‐doped hydroxyapatite (xZn = 0; 0.4; H‐LF and 4ZH‐LF) were synthesized by an adapted method (and dried by lyophilization) and characterized through a series of analytical techniques in order to evaluate their stability, morphological, and biological properties.

Is redo percutaneous mitral balloon valvuloplasty (PMV) indicated in patients with post-PMV mitral restenosis?

Journal of the American College of Cardiology, 1999
The purpose of this study was to assess the immediate and long-term outcome of repeat percutaneous mitral balloon valvuloplasty (PMV) for post-PMV mitral restenosis.Symptomatic mitral restenosis develop in 7% to 21% of patients after PMV. Currently, most of these patients are referred for mitral valve replacement.

Methodologies for Dataset Analysis in Regard to Obtaining Material Characteristics Using Lamb Waves

Macromolecular Symposia, EarlyView.
ABSTRACT Nondestructive testing has been a fundamental technique in material characterization for an extended period, offering the distinct advantage of preserving the integrity of the tested specimen. Among the conventional methodologies, the pulse‐echo technique has been widely employed for the determination of the Young's modulus and Poisson's ratio

Notes on the Calculation of the PMV Index by Means of Apps

Energy Procedia, 2016
Abstract In this work, all existing smartphone and web applications for the calculation of the PMV index running on different platforms for mobile devices have been compared with a reference software compliant with ISO 7730 Standard. Unfortunately, only four apps take into account all the six variables responsible for the thermal sensation (air ...

Dynamics of a Rod Attached to a Rotating Hinge

Macromolecular Symposia, EarlyView.
ABSTRACT The dynamics of a rod attached to a rotating hinge, also interpreted as a physical pendulum in a rotating frame, provide a valuable mechanical model for analyzing the complex oscillatory behavior of helicopter rotor blades. This simplified system captures essential features of blade flapping and in‐plane motions influenced by inertial and ...

Plasmepsins as Antimalarial Drug Targets—Then, Now, and the Future

Medicinal Research Reviews, EarlyView.
ABSTRACT Malaria is a devastating disease caused by Plasmodium parasites. Plasmodium parasites express ten cathepsin D‐like aspartyl proteases, called plasmepsins (PMs). These PMs have diverse roles fulfill diverse functions throughout the parasite's lifecycle, though several exhibit functional redundancies. Among them, PMV, PMIV, and PMX are essential
