To enable the practical application of lithium metal batteries, it is crucial to address the challenges of dendrite growth and volume expansion in lithium metal anodes. A 3D framework offers an effective solution to regulate the lithium plating/stripping process. In this work, we present a 3D mixed ion-electron conducting (MIEC) framework as a lithium metal anode, achieved by conformally coating carbon nanotubes (CNTs) onto LiLaTiO (LLTO) particles.

Objectives: Ascending aortic length has recently been recognized as a novel predictor of adverse events in aortic diseases, but its prognostic value in type A intramural haematoma is unknown. We aimed to evaluate the association between ascending aortic length and outcomes in patients with type A intramural haematoma initially managed medically.
Methods: We retrospectively analysed patients with acute type A intramural haematoma.
Polycarbonate/acrylonitrile butadiene styrene (PC/ABS) blends are widely used as engineering plastic alloys; however, they have a low fire safety level. To improve the flame-retardant property of PC/ABS, a zirconium-based metal-organic framework material (UiO-66) was synthesized with zirconium chloride and terephthalic acid and used as a flame-retardant cooperative agent. Its flame-retardant performance and mode of action in the PC/ABS blends were carefully investigated.

Hydrogen (H) has emerged as a highly promising energy carrier owing to its remarkable energy density and carbon emission-free properties. However, the widespread application of H fuel has been limited by the difficulty of storage. In this work, spontaneous electrochemical hydrogen production is demonstrated using hydrazine (NH) as a liquid hydrogen storage medium and enabled by a highly active Co catalyst for hydrazine electrooxidation reaction (HzOR).

However, simultaneously boosting the ionic conductivity (σ) and lithium-ion transference number (t) of liquid electrolyte confined in porous matrix remains challenging. Herein, we report a novel Janus MOFLi/MSLi QSEs with asymmetric porous structure to inherit the benefits of both mesoporous and microporous hosts.

Methods: After admission (before surgery), attending surgeons were asked to rate the mortality on a scale of 1 to 10, with 1 to 3 representing unlikely, 4-6 possible, and 7-10 very likely.
Background: The weekend effect refers to the mortality difference for patients admitted/operated on weekends compared to those on weekdays. The study aimed to provide new evidence on the impact of the weekend effect on acute type A aortic dissection (ATAAD).
Methods: Primary endpoints were operative mortality, stroke, paraplegia, and continuous renal replacement therapy (CRRT).
Sodium-ion batteries (SIBs) are promising candidates for large-scale energy storage. Increasing the energy density of SIBs demands anode materials with high gravimetric and volumetric capacity. To overcome the drawback of low density of conventional nanosized or porous electrode materials, compact heterostructured particles are developed in this work with improved Na storage capacity by volume, which are composed of SnO nanoparticles loaded into nanoporous TiO followed by carbon coating.

Objectives: Isolated abdominal aortic dissection (IAAD) is extremely rare, with its optimal treatment and intervention timing remaining poorly understood. We aimed to study the natural history of IAAD and facilitate better clinical decision.
Methods: Consecutive patients admitted to our institution from January 2016 to April 2021 were enrolled and followed up prospectively.
Objective: The right axillary artery is currently recommended for arterial cannulation in surgery for acute type A aortic dissection. However, the feasibility of cannulation on a dissected right axillary artery remains undetermined. The objective was to examine the feasibility of cannulation on a dissected right axillary artery.

Mesoporous silicas tethered with anions were developed as quasi-solid electrolytes for Li-metal batteries. The high grafted density of trifluoromethylsulfonyl (-NTf) groups and their uniformly distributed negative charge endow MCM41-NLiTf with a room temperature single Li-ion conductivity of up to 2.4 × 10 S cm, which enables stable cycling of LFP‖Li batteries.

Methods: From January 2016 to January 2021, 895 consecutive patients with ATAAD received surgical treatment at our hospital. After applying our exclusion criteria, 508 patients were included in this research.
Objective: The aim of the study was to investigate surgical modalities and outcomes in patients with type A aortic dissection involving arch anomalies.
Method: Patients with type A aortic dissection who underwent surgical treatment at our center between January 2017 and 31 December 2020 were selected for this retrospective analysis. Data including computed tomography (CT), surgical records, and cardiopulmonary bypass records were analyzed.
Micro-/macroangiopathy, neuropathy and prolonged inflammation are common in diabetic wound, however, traditional wound dressing cannot treat these problems in the same time. Herein, we developed a multifunctional hydrogel with promoted angiogenesis, cell proliferation and anti-inflammation ability to treat diabetic wound. The hydrogel was composed of natural polymers, including gelatin and chitosan, which have excellent biocompatibility.

Open arch repair under hypothermic circulatory arrest with selective antegrade cerebral perfusion (HCA/sACP) is safe and efficient but associated with inevitable hypothermia and ischemia-reperfusion injury. The aortic balloon occlusion (ABO) technique is shown to be organ protective by allowing higher temperature and shorter circulatory arrest time.

This study examined the incidence, management, and outcomes of patients with CM secondary to ATAAD and proposes a modified Neri classification. Methods: Between 2015 and 2020, out of 1018 patients who underwent surgical repair for ATAAD, 137 presented with CM, including 68 (49.

Injectable natural polymer hydrogels with conductivity ability are highly desirable as cell delivery vehicles to repair infarct myocardium and restore the cardiac function. In this work, we developed a hydrogel system based on gelatin methacrylate (GelMA) and oxidized dextran (ODEX) as cell delivery vehicles for MI.

To further investigate the role of GATAD2B in cell fate determination of human ESCs, we generated two GATAD2B homozygous knockout human ESC lines by CRISPR/Cas9 technology. The cell line exhibits normal karyotype and typical stem cell morphology, following the high expression of pluripotent genes and differentiation potential in vitro.

For patients with acute type A aortic dissection, strongly suspected of having concomitant severe coronary artery disease (CAD), preoperative or intraoperative coronary angiography has been recommended. However, conventional selective coronary angiography in this setting may extend the dissection or aortic rupture. We present the use of intraoperative open-heart coronary angiography in a patient with acute type A aortic dissection.
