Magnetic fluid hyperthermia (MFH) is considered a promising therapeutic technique for the treatment of cancer cells, in which magnetic nanoparticles (MNPs) with superparamagnetic behavior generate mild-temperatures under an AC magnetic field to selectively destroy the abnormal cancer cells, in detriment of the healthy ones. However, the poor heating efficiency of most NMPs and the imprecise experimental determination of the temperature field during the treatment, are two of the majors drawbacks for its clinical advance. Thus, in this work, different MNPs were developed and tested under an AC magnetic field (~1.10 kA/m and 200 kHz), and the heat generated by them was assessed by an infrared camera. The resulting thermal images were processed in MATLAB after the thermographic calibration of the infrared camera. The results show the potential to use this thermal technique for the improvement and advance of MFH as a clinical therapy.

This commentary considers the implementation of the Alternative Investment Fund Managers Directive (AIFMD) by the European Commission. The AIFMD creates an internal market for asset management and as an endeavour to develop market-based finance is an important piece of legislation for the European economy. The author, Mirzha de Manuel Aramendía, considers the implementation of some of the provisions that raised concern among industry participants. He finds that, on balance, a practical and flexible approach to implementation has been followed that should help secure the success of the framework, which at present is still uncertain. The commentary also considers the remuneration guidelines adopted recently by the European Securities and Markets Authority (ESMA). It encourages EU and national authorities to commit to the success of the AIFMD framework, as part of a broader effort to develop capital markets and reduce the historical reliance of the European economy on bank finance.
