Perivascular radiofrequency renal denervation lowers blood pressure and ameliorates cardiorenal fibrosis in spontaneously hypertensive rats. [PDF]

PLoS ONE, 2017
BACKGROUND:Catheter-based renal denervation (RDN) is a promising approach to treat hypertension, but innervation patterns limit the response to endovascular RDN and the post-procedural renal artery narrowing or stenosis questions the endovascular ...

Laser ablation loading of a radiofrequency ion trap [PDF]

Applied Physics B 107, 883 (2012), 2011
The production of ions via laser ablation for the loading of radiofrequency (RF) ion traps is investigated using a nitrogen laser with a maximum pulse energy of 0.17 mJ and a peak intensity of about 250 MW/cm^2. A time-of-flight mass spectrometer is used to measure the ion yield and the distribution of the charge states. Singly charged ions of elements

From Basics to Frontiers: A Comprehensive Review of Plasma-Modified and Plasma-Synthesized Polymer Films [PDF]

Polymers (2023), 2023
This comprehensive review begins by tracing the historical development and progress of cold plasma technology as an innovative approach to polymer engineering. The study emphasizes the versatility of cold plasma derived from a variety of sources including low-pressure glow discharges (e.g., radiofrequency capacitively coupled plasmas) and atmospheric ...

Laser ablation production of Ba, Ca, Dy, Er, La, Lu, and Yb ions [PDF]

Appl. Phys. B 123, 99 (2017), 2016
We use a pulsed nitrogen laser to produce atomic ions by laser ablation, measuring the relative ion yield for several elements, including some that have only recently been proposed for use in cold trapped ion experiments. For barium, we monitor the ion yield as a function of the number of applied ablation pulses for different substrates.

Clinical characteristics of patients with atrial flutter before radiofrequency ablation

Journal of V. N. Karazin Kharkiv National University: Series Medicine, 2020
Introduction. Radiofrequency ablation (RFA) is today the method of choice for the ineffective medical treatment of atrial fibrillation (AF), but its course is often complicated by comorbid pathology.
