Promoting Angiogenesis/Osteogenesis by a New Copper/Magnesium Hydroxide Hybrid Nanoparticle: In Vitro and In Vivo Investigation.
J Biomed Mater Res A
January 2025
Marquette University School of Dentistry, Milwaukee, Wisconsin, USA.
In this study, a new hybrid nanoparticle composed of magnesium hydroxide and copper oxide (Mg(OH)/CuO) with an optimized ratio of magnesium (Mg) to copper (Cu) was designed and incorporated into a 3D-printed scaffold made of polycaprolactone (PCL) and gelatin. These hybrid nanostructures (MCNs) were prepared using a green, solvent-free method. Their topography, surface morphology, and structural properties were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS).

Methods: a cross-sectional study in Brazil between August/2020 and March/2021. We utilized the EPI-APS COVID-19 instrument and its adapted version for resident professionals.
Follow-up of immediate postpartum intrauterine device insertion: a scoping review protocol.
BMJ Open
December 2024
Obstetrics & Gynecology, University of Campinas, Campinas, São Paulo, Brazil.
Introduction: The intrauterine device (IUD) inserted immediately after delivery is a safe and effective measure for preventing unplanned pregnancies. Despite exhibiting a higher expulsion rate compared with later insertions, it proves cost-effective due to the high rate of continuity of the method. There is still a gap in the literature regarding the optimal strategy for monitoring these patients, whether it should be through clinical examination, ultrasound or both.

Division of Pediatric and Adult Congenital Cardiac Surgery, Maria Fareri Children's Hospital, Department of Surgery, Westchester Medical Center, New York Medical College, Valhalla, NY, USA.
Mitral annular calcifications have been known to increase complexity during mitral valve replacement (MVR). Standard procedure requires decalcification followed by reconstruction of the mitral annulus prior to placing the prosthesis. While this is the ideal technique, it is not feasible in every patient due to the associated risks.
