Comparing clinical outcomes of vitamin K antagonists vs non-vitamin K antagonists in anticoagulant therapy for mesenteric venous thrombosis.

Objective: Non-vitamin K antagonist oral anticoagulants have shown similar efficacy and lower bleeding rates than vitamin K antagonists for venous thromboembolism. However, this has not been proven in mesenteric vein thrombosis. This study aimed to compare the clinical outcomes of vitamin K antagonists and non-vitamin K antagonist oral anticoagulants.

Generalized Helmholtz model describes capacitance profiles of ionic liquids and concentrated aqueous electrolytes.

In this work, we propose and validate a generalization of the Helmholtz model that can account for both "bell-shaped" and "camel-shaped" differential capacitance profiles of concentrated electrolytes, the latter being characteristic of ionic liquids. The generalization is based on introducing voltage dependence of both the dielectric constant "ϵr(V)" and thickness "L(V)" of the inner Helmholtz layer, as validated by molecular dynamics (MD) simulations. We utilize MD simulations to study the capacitance profiles of three different electrochemical interfaces: (1) graphite/[BMIm+][BF4-] ionic liquid interface; (2) Au(100)/[BMIm+][BF4-] ionic liquid interface; (3) Au(100)/1M [Na+][Cl-] aqueous interface.

Surgical Strategies and Long-Term Outcomes for Complex Coral Reef Aorta with Multisegmental Involvement: A Case Report.

Coral reef aorta (CRA) is a rare condition characterized by the distribution of rock-hard calcifications in the visceral part of the aorta, leading to potentially life-threatening symptoms, such as hypertension, congestive heart failure, and limb and visceral ischemia. The patient was a 54-year-old female who presented with leg claudication and was diagnosed with CRA using computed tomography. CRA affected the descending thoracic and abdominal aortas, including the visceral portion, leading to reduced perfusion of both limbs and the left kidney.

Case Report: Hybrid approach as a Rescue Treatment in a patient with vascular Ehlers-Danlos Syndrome.

Vascular Ehlers-Danlos Syndrome (vEDS) is a rare connective tissue disorder associated with gene mutation encoding type III collagen. Given the possible fatal prognosis if not treated timely, it is important to suspect and diagnose as soon as possible. Despite advances in endovascular technique, access point complications remain a serious challenge in patients with vEDS.

Outcomes of Isolated Endarterectomy and Patch Angioplasty of the Common Femoral Artery According to Current Inclusion Criteria for Endovascular Treatment.

Purpose: This study aimed to evaluate the outcomes of isolated common femoral endarterectomy with patch angioplasty (IFEA) in the endovascular era.

Materials And Methods: In 2012-2022, 189 limbs underwent femoral endarterectomy with patch angioplasty. Of them, 45 IFEAs were included.

Interference of electrical double layers: Confinement effects on structure, dynamics, and screening of ionic liquids.

Ionic liquids are widely used as electrolytes in electronic devices in which they are subject to nanoconfinement within nanopores or nanofilms. Because the intrinsic width of an electrical double layer is on the order of several nanometers, nanoconfinement is expected to fundamentally alter the double layer properties. Furthermore, in confined systems, a large portion of the ions are interfacial, e.

In silico construction of a flexibility-based DNA Brownian ratchet for directional nanoparticle delivery.

Brownian particles confined in a system with periodic and asymmetric potential can be transported in a specific direction along the potential by repetitively switching the potential on and off. Here, we propose a DNA-based Brownian ratchet for directional transport of positively charged nanoparticles in which nanoparticle delivery follows the path dictated by a single, long, double-stranded DNA. We performed Brownian dynamics simulations to prove its realization using coarse-grained models.

Directional rolling of positively charged nanoparticles along a flexibility gradient on long DNA molecules.

Directing the motion of molecules/colloids in any specific direction is of great interest in many applications of chemistry, physics, and biological sciences, where regulated positioning or transportation of materials is highly desired. Using Brownian dynamics simulations of coarse-grained models of a long, double-stranded DNA molecule and positively charged nanoparticles, we observed that the motion of a single nanoparticle bound to and wrapped by the DNA molecule can be directed along a gradient of DNA local flexibility. The flexibility gradient is constructed along a 0.

Molecular epidemiology of carbapenem-resistant Acinetobacter baumannii isolates from a Korean hospital that carry bla.

To elucidate the epidemicity of carbapenem-resistant Acinetobacter baumannii (CRAB), we investigated the antimicrobial susceptibility, the genetic basis of antimicrobial resistance, and the ability to form biofilms of 147 CRAB isolates collected between 2013 and 2015 from a Korean hospital based on sequence types (STs). Six different STs were identified: ST191 (n=47) and ST208 (n=36) were clones that had already been identified in the study hospital, whereas ST229 (n=28), ST369 (n=18), ST357 (n=17), and ST552 (n=1) were previously unknown. All the CRAB isolates exhibited an extensively drug-resistance.
