Background: Moderate to severe acne scars pose a therapeutic challenge and often require multimodal treatments. Ablative fractional laser (AFL) and fractional microneedling radiofrequency (FMR) are commonly used, but their alternating application has not been fully studied.
Patients And Methods: In this prospective, randomized, single-blind, split-face trial, 20 patients (Fitzpatrick III-IV) received four treatments at 4-week intervals: one facial side underwent alternating FMR (sessions 1, 3) and AFL (sessions 2, 4), while the contralateral side received AFL alone.

ObjectiveRecurrent varicose veins (RVVs) following open surgical procedures are common and present significant treatment challenges. Redo open surgery (rOS) presents risks leading to a need for alternative treatment options. This study compares the safety and efficacy of ultrasound-guided foam sclerotherapy (UGFS), used to treat recurrent reflux and remove neovascular and tributary venous networks in the thigh, to redo open surgery (rOS) for the treatment of C2r.

Aim To compare the long-term effectiveness of cryoballoon ablation (CBA) and radiofrequency ablation (RFA) in patients with atrial fibrillation (AF).Material and methods This retrospective single-site study included 597 patients with AF who had undergone CBA (n=241) or RFA (n=356) between 2016 and 2024. The study participants included 355 men (59.

Background: In catheter-based radiofrequency ablation (RFA), energy is delivered to heterogeneous thin-walled tissues to induce therapeutic heating. Variations in electrical and mechanical properties of tissue contents have a great effect on outcomes.
Purpose: The objective of this study is to develop models that replicate tissue heterogeneity and visualize ablation zones for effective evaluation and optimization.

Biomolecular dynamics in the microsecond-to-millisecond (µs-ms) timescale are linked to various biological functions, such as enzyme catalysis, allosteric regulation, and ligand recognition. In solution state NMR, Carr-Purcell-Meiboom-Gill (CPMG) relaxation dispersion experiments are commonly used to probe µs-ms timescale motions, providing detailed kinetic, thermodynamic, and mechanistic information at the atomic level. For investigating conformational dynamics in high-molecular-weight biomolecules, methyl groups serve as ideal probes due to their favorable relaxation properties, and C CPMG relaxation dispersion is widely employed for characterizing dynamics in selectively CH-labeled samples.
