Severe tricuspid regurgitation is a debilitating condition that associated with substantial morbidity and often poor quality of life. Decreasing may reduce symptoms improve clinical outcomes in patients this disease.We conducted prospective randomized trial percutaneous transcatheter edge-to-edge repair (TEER) for severe regurgitation. Patients symptomatic were enrolled at 65 centers the United States, Canada, Europe randomly assigned 1:1 ratio to receive either TEER or medical therapy...
van der Waals (vdW) magnets are receiving ever-growing attention nowadays due to their significance in both fundamental research on low-dimensional magnetism and potential applications spintronic devices. The high crystalline quality of vdW is the key maintaining intrinsic magnetic electronic properties, especially when exfoliated down two-dimensional limit. Here, ultrahigh-quality air-stable CrSBr crystals synthesized using direct solid-vapor synthesis method. single crystallinity spatial...
Producing hydrogen by unassisted solar water splitting is one essential step to make direct fuel conversion a viable energy source. To date, however, there has been no demonstration of stable photoelectrodes for high-efficiency photoelectrochemical splitting. In this work, we report that GaInP2/GaAs/Ge triple-junction (3J) photocathode protected multifunctional GaN nanostructures can enable both efficient and relatively A 12.6% solar-to-hydrogen (STH) efficiency measured without any external...
The demand for high-throughput electron tomography is rapidly increasing in biological and material sciences. However, this 3D imaging technique computationally bottlenecked by alignment reconstruction which runs from hours to days. We demonstrate real-time with dynamic tomographic visualization enable rapid interpretation of specimen structure immediately as data collected on an microscope. Using geometrically complex chiral nanoparticles, we show volumetric can begin less than 10 minutes a...
ScAlN is an emerging ultrawide bandgap semiconductor for next-generation radio frequency electronic devices. Here, we show that the material quality of grown by molecular beam epitaxy can be drastically improved alloying with Ga. The resulting quaternary alloy ScAlGaN exhibits a single-phase wurtzite structure, atomically smooth surface, high crystal quality, sharp interface, and low impurity concentration. Most significantly, oxygen incorporation in found to three four orders magnitude...
Measuring the three-dimensional (3D) distribution of chemistry in nanoscale matter is a longstanding challenge for metrological science. The inelastic scattering events required 3D chemical imaging are too rare, requiring high beam exposure that destroys specimen before an experiment completed. Even larger doses to achieve resolution. Thus, mapping has been unachievable except at lower resolution with most radiation-hard materials. Here, high-resolution achieved near or below one-nanometer Au-Fe
Marathon running is presumed to improve cardiovascular risk, but health benefits of high volume are unknown. High-resolution coronary computed tomography angiography and cardiac risk factor assessment were completed in women with long-term marathon histories compare sedentary similar factors.Women who had run at least one per year for 10-25 yr underwent angiography, 12-lead ECG, blood pressure heart rate measurement, lipid panel, a demographic/health survey. Sedentary matched controls...
Angina and no obstructive coronary artery disease (ANOCA) is common. A potential cause of angina in this patient population a myocardial bridge (MB). We aimed to study the anatomical haemodynamic characteristics an MB patients with ANOCA.Using intravascular ultrasound (IVUS), we identified 184 MBs 154 patients. evaluated length, arterial compression, halo thickness. muscle index (MMI) was defined as length×halo Haemodynamic testing performed using intracoronary pressure/Doppler flow wire at...
Although rare instances of cardiac injury or arrhythmias have been reported in acute liver failure (ALF), overall, the heart is considered to be spared this condition. Troponin I, a sensitive and specific marker myocardial injury, may elevated patients with sepsis stroke without underlying coronary syndrome, indicating unrecognized these settings. We sought determine whether subclinical might also occur failure. Serum troponin I levels were measured 187 enrolled US Acute Liver Failure Study...
Abstract Efforts to map atomic-scale chemistry at low doses with minimal noise using electron microscopes are fundamentally limited by inelastic interactions. Here, fused multi-modal microscopy offers high signal-to-noise ratio (SNR) recovery of material nano- and atomic-resolution coupling correlated information encoded within both elastic scattering (high-angle annular dark-field (HAADF)) spectroscopic signals (electron energy loss (EELS) or energy-dispersive x-ray (EDX)). By linking these...
GaN-based nanostructures are increasingly being used for a broad range of electronic as well optoelectronic device applications, and more recently artificial photosynthesis solar fuel generation. We have performed detailed investigation the molecular beam epitaxy characterization Mg-doped p-type InGaN micro-network with lateral dimensions reaching small few nanometers. Mg doping shows clear impact on carrier dynamics photocatalytic performance such nanostructures. The exhibit remarkable...
Background: One-year outcomes of the TRILUMINATE Pivotal trial found that transcatheter edge-to-edge repair (TEER) for treatment severe, symptomatic tricuspid regurgitation (TR) improved quality-of-life compared with medical therapy alone similar rates mortality and heart failure hospitalization (HFH). However, additional follow-up is necessary to determine prolonged benefits TEER. Methods: A total 572 patients TR were randomized either TEER+medical (Device) or (Control). Two-year...
While the surface-bulk correspondence has been ubiquitously shown in topological phases, relationship between surface and bulk Landau-like phases is much less explored. Theoretical investigations since 1970s for semi-infinite systems have predicted possibility of order emerging at a higher temperature than bulk, clearly illustrating counterintuitive situation greatly enriching phase transitions. But experimental realizations this prediction remain missing. Here, we demonstrate...
The aim of this study was to evaluate the risk future variceal bleeding, based on endoscopic ultrasound measurement sum cross-sectional surface area (CSA) all esophageal varices in distal esophagus.Twenty-eight patients with portal hypertension and varices, but no prior history were evaluated using (20-MHz probe, Microvasive, Boston, MA; Olympus, Tokyo, Japan). entire esophagus imaged, an image selected at a point where appeared largest. This digitized, CSA measured (Image Pro Plus, Silver...
Transaxillary access has been the most frequently used nonfemoral route for transcatheter aortic valve replacement (TAVR) with a self-expanding valve. Use of transcarotid TAVR is increasing; however, comparative data on these methods are limited. We compared outcomes following or transaxillary self-expanding, supra-annular valve.The Transcatheter Valve Therapy Registry was queried procedures using and between July 2015 June 2021. Patients received Evolut R, PRO, PRO + (Medtronic) had 1-year...
