Effect of differences in proximal neck angles on biomechanics of abdominal aortic aneurysm based on fluid dynamics.

Background: This study aimed to analyze the effect of proximal neck angulation on the biomechanical indices of abdominal aortic aneurysms (AAA) and to investigate its impact on the risk of AAA rupture.

Methods: CT angiography (CTA) data of patients with AAA from January 2015 to January 2022 were collected. Patients were divided into three groups based on the angle of the proximal neck: Group A (∠β ≤ 30°), Group B (30°<∠β ≤ 60°), and Group C (∠β > 60°).

Manipulating Surface Band Bending of III-Nitride Nanowires with Ambipolar Charge-Transfer Characteristics: A Pathway Toward Advanced Photoswitching Logic Gates and Encrypted Optical Communication.

The operational principle of semiconductor devices critically relies on the band structures that ultimately govern their charge-transfer characteristics. Indeed, the precise orchestration of band structure within semiconductor devices, notably at the semiconductor surface and corresponding interface, continues to pose a perennial conundrum. Herein, for the first time, this work reports a novel postepitaxy method: thickness-tunable carbon layer decoration to continuously manipulate the surface band bending of III-nitride semiconductors.

Lycium barbarum glycopeptide targets PER2 to inhibit lipogenesis in glioblastoma by downregulating SREBP1c.

Lycium barbarum polysaccharide (LBP) is a substance with various biological activities extracted from Lycium barbarum. LbGPs are peptidoglycans with a short peptide backbone and a complex, branched glycan moiety, which is further extracted and isolated from LBPs. Previous studies have shown that LbGP can inhibit cancer cell growth, but its specific mechanism is not completely clear.

Achieving Record-High Photoelectrochemical Photoresponse Characteristics by Employing CoO Nanoclusters as Hole Charging Layer for Underwater Optical Communication.

The physicochemical properties of a semiconductor surface, especially in low-dimensional nanostructures, determine the electrical and optical behavior of the devices. Thereby, the precise control of surface properties is a prerequisite for not only preserving the intrinsic material quality but also manipulating carrier transport behavior for promoting device characteristics. Here, we report a facile approach to suppress the photocorrosion effect while boosting the photoresponse performance of n-GaN nanowires in a constructed photoelectrochemical-type photodetector by employing CoO nanoclusters as a hole charging layer.

Anisotropic photoresponse behavior of a LaAlO single-crystal-based vacuum-ultraviolet photodetector.

Nowadays, vacuum-ultraviolet (VUV) photodetectors (PDs) have attracted extensive attention owing to their potential applications in space exploration, radiation monitoring, and the semiconductor industry. Benefiting from its intrinsic ultra-wide band-gap, chemical robustness, and low-cost features, LaAlO shows great promise in developing next-generation compact, cheap, and easy-to-fabricate VUV PDs. In this work, we report the unique anisotropic photoresponse behavior of LaAlO single crystals for VUV photodetection applications.

Intraluminal Diverticular Duodenal Duplication With Recurrent Abdominal Pain: A Case Report.

Duodenal duplication is a rare congenital anomaly and may manifest as pancreatitis, gastrointestinal bleeding, abdominal pain, perforation, and obstruction. Here, we present a case of intraluminal diverticular duodenal duplication (IDDD) in a child with recurrent abdominal pain caused by a large hole-like structure in the duodenal bulb. This condition has rarely been reported.

Is percutaneous access superior to cutdown access for endovascular abdominal aortic aneurysm repair? A meta-analysis.

Objective: The objective is to investigate whether percutaneous access (pEVAR) is superior to cutdown access (cEVAR) in terms of safety and efficacy during endovascular repair of abdominal aortic aneurysms (AAAs).

Methods: We searched PubMed, Embase, and Cochrane Library from January 1999 to December 2020 for studies reporting on the comparison between percutaneous and cutdown techniques for endovascular repair of AAAs. Outcomes evaluated were technical success rates, access site-related complications and operative time, and hospital stay.

Endovascular Repair of an Aneurysm Arising from a Celiomesenteric Trunk.

Celiac axis (CA) aneurysm is a rare vascular condition, consisting of only 3.6-4% of visceral artery aneurysms but is frequently life threatening and can result in death. A celiomesenteric trunk (CMT) is an anatomic anomaly in which the celiac and superior mesenteric arteries arise from a common trunk.

Multiple domains of bacterial and human Lon proteases define substrate selectivity.

The Lon protease selectively degrades abnormal proteins or certain normal proteins in response to environmental and cellular conditions in many prokaryotic and eukaryotic organisms. However, the mechanism(s) behind the substrate selection of normal proteins remains largely unknown. In this study, we identified 10 new substrates of F.
