Dipole charge density mapping integrated in remote magnetic navigation: First-in-human feasibility study

International Journal of Cardiology: Heart & Vasculature, 2022
Aims: Robotic magnetic navigation (RMN) provides increased catheter precision and stability. Formerly, only the CARTO 3 mapping system was integrated with the RMN system (CARTO-RMN).

Serum bile acids as a prognostic biomarker in biliary atresia following Kasai portoenterostomy

Hepatology, EarlyView., 2022
Serum bile acid levels predict outcomes in patients with biliary atresia who achieve normalized bilirubin levels after Kasai portoenterostomy. Abstract Background and Aims In biliary atresia, serum bilirubin is commonly used to predict outcomes after Kasai portoenterostomy (KP).

Facile construction of irinotecan loaded mesoporous nano-formulation with surface-initiated polymerization to improve stimuli-responsive drug delivery for breast cancer therapy

Heliyon, 2023
This work uses rice husk to fabricate mesoporous silica nanoparticles (D-RMN) for breast cancer therapy. The biocompatible dual-responsive (DAN-RMN) was developed by polymerizing acrylic acid (AA) and n-isopropyl acrylamide (NIPAM) on the DV-RMN surface ...

Comparison of the Mid-Term Outcomes of Robotic Magnetic Navigation-Guided Radiofrequency Ablation versus Cryoballoon Ablation for Persistent Atrial Fibrillation

Journal of Cardiovascular Development and Disease, 2022
Introduction: Currently, numerous ablation techniques are available for atrial fibrillation (AF), in addition to manual radio frequency ablation. The aim of this prospective, non-randomized concurrent controlled trial was to compare the mid-term efficacy

Phosphorus NMR analysis of human white matter in mixed non-ionic detergent micelles.

Journal of Lipid Research, 1988
In order to study the lipid composition of human white matter, we have developed a 31P NMR spectroscopy method, which allows the determination and quantitation of the main phospholipids found in biological membranes.

Coalescence of Liquid Drops [PDF]

, 1999
When two drops of radius $R$ touch, surface tension drives an initially singular motion which joins them into a bigger drop with smaller surface area. This motion is always viscously dominated at early times.
