DNA- and MNAzymes are nucleic acid-based enzymes (NAzymes), which infiltrated the otherwise protein-rich field of enzymology three decades ago. The 10-23 core NAzymes are one of the most widely used and well-characterized NAzymes, but often require elevated working temperatures or additional complex modifications for implementation at standard room temperatures. Here, we present a generally applicable method, based on thermodynamic principles governing hybridization, to re-engineer the existing 10-23 core NAzymes for use at 23 °C...

Transesophageal echocardiography (TEE) provides real-time information on both morphology and hemodynamics without radiation exposure or contrast media, interruption of surgical procedures, or need for transferring the patient to other division, and thus can be used as intraoperative monitoring as well as diagnostic imaging. TEE is helpful for confirming the adequacy of routine surgical procedures, ruling out an occurrence of unexpected adverse events, or even navigating the manipulations of cannulae and catheters...

Perovskite light-emitting field-effect transistors (PeLEFETs) provide a versatile device architecture to control transport and electroluminescence properties of hybrid perovskites, enabling injection of high charge carrier density and spatial control of the radiative recombination zone. Ionic screening and organic cation polarization effects typical of metal-halide perovskites, however, critically affect PeLEFET efficiency and reliability. In this work, we demonstrate a new device operation mode based on high-frequency modulation of the applied voltages, which allows significant reduction of ionic drift/screening in methylammonium lead iodide light-emitting transistors...

Symptomatic aortic stenosis remains a surgical disease, with aortic valve replacement resulting in symptom reduction and improvement in survival. For patients who are deemed a higher surgical risk, Transcatheter aortic-valve replacement (TAVR) is a viable, less invasive and increasingly common alternative. The study compares early outcomes in patients treated within one year of the commencement of TAVR program in a community hospital against outcomes of TAVR patients from nationwide reported data (Society of Thoracic Surgeons/ American College of Cardiology TVT registry)...

The fabrication of high-performance solid-state silicon quantum-devices requires high resolution patterning with minimal substrate damage. We have fabricated room temperature single-electron transistors (SETs) based on point-contact tunnel junctions using a hybrid lithography tool capable of both high resolution thermal scanning probe lithography and high throughput direct laser writing. The best focal z-position and the offset of the tip- and the laser-writing positions were determined in-situ with the scanning probe...

Hierarchical SnO₂ nanocrystallites aggregates (NAs) were prepared with a simple room temperature⁻based aqueous solution method followed by simple freeze-drying treatment. The as-prepared SnO₂ NAs were subsequently combined with SnO₂ nanosheet⁻based structures from the viewpoint of a function-matching strategy, and under an optimized condition, a power conversion efficiency (PCE) of 5.59% was obtained for the resultant hybrid photoanode, a remarkable 60% enhancement compared to that of dye-sensitized solar cells (DSCs) fabricated with bare SnO₂ NAs architecture...

BACKGROUND: Acute care surgery (ACS) was proposed to address a general surgery workforce crisis; however, the ACS workforce composition is unknown. A national survey was conducted to determine the differences in the emergency general surgery (EGS) workforce between ACS and non-ACS hospitals. METHODS: The American Hospital Association (AHA) Annual Survey of Hospitals database was queried to identify acute care general hospitals. A hybrid mail/electronic survey was sent to 2811 acute care hospitals that met the inclusion criteria of hospitals that care for adult patients (≥18 years old) with an emergency room (ER), ≥ 1 operating room (OR), and 24-h ER access...

The hybrid emergency room (hybrid ER) system was first established in 2011 in Japan. It is defined as an integrated system including an ER, emergency computed tomography (CT) and interventional radiology (IVR) rooms, and operating rooms. Severe trauma patients can undergo emergency CT examinations and therapies (surgeries) without being transferred. The hybrid ER system is attracting attention because trauma resuscitation using this system has been reported to potentially improve the mortality rate in severe trauma patients...

BACKGROUND: Preoperative computed tomography (CT)-guided dye localization is essential for the surgical treatment of small lung nodules and is mostly performed by radiologists in the CT room. Several studies reported their early experiences of preoperative localization in the hybrid operating room. A comparison between localization in the CT and hybrid rooms has not been reported. Therefore, we compared the outcomes of preoperative localization in the hybrid and CT rooms. METHODS: This study included patients who underwent preoperative CT-guided dye localization for thoracoscopic lung tumor surgery in the hybrid operation (n=25) and CT (n=283) rooms at our institute...

OBJECTIVE: Dural arteriovenous fistulas (dAVFs) are abnormal direct shunts between the occipital or meningeal artery and a meningeal vein or dural venous sinus. Treatment strategies include endovascular, microsurgical, stereotactic radiosurgical, or combined interventions. With few previous reports focused on dAVF treatment in a hybrid operating room (hOR), the authors reviewed their 6-year experience in this unique setting for these complex fistulas. METHODS: Patients with complex cerebral dAVFs underwent endovascular and microsurgical treatment in the hOR...

An accessory middle cerebral artery (AMCA), which mainly acts in the collateral circulation of the middle cerebral artery (MCA), is a rare anatomic malformation. Similar to other intracranial vessels, cerebrovascular disease can occur in the AMCA. However, the development of an arteriovenous malformation (AVM) in the AMCA is very rare, especially in conjuction with developmental venous anomalies (DVAs). Here, a rare case of an AMCA combined with an AVM and a DVA was reported. The patient was a 47-year-old female with intracranial hemorrhage at symptom onset...

Improvements in endovascular technologies and development of custom-made fenestrated and branched endografts currently allow clinicians to treat complex aortic lesions such as thoraco-abdominal and aortic arch aneurysms once treatable with open repair only. These advances are leading to an increase in the complexity of endovascular procedures which can cause long operation times and high levels of radiation exposure. This in turn places pressure on the vascular surgery community to display more superior interventional skills and radiological practices...
