Nuclear Magnetic Resonance (NMR) spectroscopy is a powerful analytical technique with a wide range of applications. To support the analysis of diverse and complex samples, various NMR tools and accessories have been created. Three-dimensional (3D) printing is an underutilized production method for NMR hardware, mainly due to the lack of H NMR background-free resins.

Background: Data on atrial fibrillation (AF) ablation using high-power short-duration (HPSD) ablation in patients over 80 years are lacking.
Objective: This study aimed to compare the safety and efficacy of paroxysmal and persistent AF ablation using an HPSD (60-90 W/4-8 sec) vs conventional ablation (30-40 W/30 sec) in a propensity score-matched cohort of patients older than 80 years.
Methods: Overall, 232 consecutive patients aged over 80 years undergoing AF ablation were included.

Tailoring surface characteristics is key to guiding scaffold interaction with the biological environment, promoting successful biointegration while minimizing immune responses and inflammation. In cardiac tissue engineering, polyvinylidene fluoride (PVDF) is a material of choice for its intrinsic piezoelectric properties, which can be enhanced through electrospinning, also enabling the fabrication of nanofibrous structures mimicking native tissue. However, the inherent hydrophobicity of PVDF can hinder its integration with biological tissues.

Radiofrequency electromagnetic radiation (RF-EMR) is ubiquitous in daily life, and the complexity of the electromagnetic environment continues to increase. Nevertheless, research on the biological effects of compound radiofrequency radiation-particularly its influence on lipid metabolism under realistic exposure scenarios-remains limited, and the underlying mechanisms are not yet fully elucidated. To investigate the impact of compound radiofrequency radiation on lipid metabolism, multi-frequency radiation exposure model both normal and obese mice were established.

In order to understand Idiopathic Environmental Intolerance attributed to Electromagnetic Fields (IEI-EMF), it has been argued that it is crucial to test for effects of radiofrequency electromagnetic fields (RF-EMF) on biomarkers, given that they can be more objective than symptom reports. While no clear evidence links RF-EMF exposure to biomarker changes, research remains limited and largely speculative due to the lack of known bioeffect mechanisms. However, there is in vitro evidence that cortisol is affected by heating, which, as RF-EMF causes heating, raises the possibility that RF-EMF exposure may increase cortisol via thermally mediated processes.
