Control of physical properties in BiFeOnanoparticles via Smand Coion doping.

Highly crystalline BiFeO(BFO), BiSmFeO(Sm-BFO) and BiFeCoO(Co-BFO) nanoparticles (NPs) were utilized as potential magnetic hyperthermia agents at two different frequencies in the radiofrequency (RF) range, and the effect of Smand Coion doping on the physical properties of the material was examined. The thermal behaviour of the as-prepared powders disclosed that the crystallization temperature of the powders is affected by the incorporation of the dopants into the BFO lattice and the Curie transition temperature is decreased upon doping. Vibrational analysis confirmed the formation of the R3c phase in all compounds through the characteristic FT-IR absorbance bands assigned to O-Fe-O bending vibration and Fe-O stretching of the octahedral FeOgroup in the perovskite, as well as through Raman spectroscopy.

Toward the Separation of Different Heating Mechanisms in Magnetic Particle Hyperthermia.

Magnetic particle hyperthermia (MPH) is a promising method for cancer treatment using magnetic nanoparticles (MNPs), which are subjected to an alternating magnetic field for local heating to the therapeutic range of 41-45 °C. In this window, the malignant regions (i.e.

Advances in Heart Failure with Preserved Ejection Fraction Management - The Role of Sacubitril-Valsartan, Pirfenidone, Spironolactone and Empagliflozin: Is Success a Series of Small Victories?

Background: Heart failure with preserved ejection fraction (HFpEF) is a syndrome characterized by marked heterogeneity in comorbidities and etiopathology substrates, leading to a diverse range of clinical manifestations and courses. Treatment options have been extremely limited and up to this day, there are virtually no pharmaceutical agents proven to reduce mortality in these patients.

Objective: The primary objective of this narrative review is to critically summarize existing evidence regarding the use of Angiotensin Receptor-Neprilysin Inhibitor (ARNI), spironolactone, pirfenidone and empagliflozin in HFpEF.

Hybrid Stents Based on Magnetic Hydrogels for Biomedical Applications.

Tremendous attention has been given to hydrogels due to their mechanical and physical properties. Hydrogels are promising biomaterials due to their high biocompatibility. Magnetic hydrogels, which are based on hydrogel incorporated magnetic nanoparticles, have been proposed in biomedical applications.

How size, shape and assembly of magnetic nanoparticles give rise to different hyperthermia scenarios.

The use of magnetic nanoparticles (MNPs) to locally increase the temperature at the nanoscale under the remote application of alternating magnetic fields (magnetic particle hyperthermia, MHT) has become an important subject of nanomedicine multidisciplinary research, focusing among other topics on the optimization of the heating performance of MNPs and their assemblies under the effect of the magnetic field. We report experimental data of heat released by MNPs using a wide range of anisometric shapes and their assemblies in different media. We outline a basic theoretical investigation, which assists the interpretation of the experimental data, including the effect of the size, shape and assembly of MNPs on the MNPs' hysteresis loops and the maximum heat delivered.
