Enhancing renewable energy utilization and energy management strategies for new energy yachts.

Hydrogen energy, due to its clean and efficient nature, has shown great potential during the current transition period in the shipbuilding industry. However, the application of hydrogen energy in ship energy systems is influenced by variations in operational load and the integration of new energy sources during actual navigation. To address these issues, this paper focuses on optimizing and scheduling the operation of ships under various navigation conditions, considering the distributed nature of hydrogen energy.

[Single Center Experience in Surgical Treatment of Extracranial Supra-Aortic Aneurysms].

Objective To evaluate the effect of surgical treatment on extracranial supra-aortic aneurysms and summarize the experience. Methods The clinical data of 10 patients undergoing surgical treatment of extracranial supra-aortic aneurysms from May 2019 to November 2023 in the Department of Vascular Surgery of Beijing Tiantan Hospital affiliated to Capital Medical University were collected.The 10 patients included 5 patients with internal carotid artery aneurysm,2 patients with subclavian artery aneurysm,2 patients with vertebral artery aneurysm,and 1 patient with internal carotid artery aneurysm combined with ipsilateral subclavian artery aneurysm.

[Clinical Effect of Surgical Reconstruction of Extracranial Vertebral Artery].

Objective To evaluate the effect of surgical reconstruction of extracranial vertebral artery and to summarize the experience. Methods The clinical data of 15 patients undergoing surgical reconstruction of extracranial vertebral artery from September 2018 to June 2022 were collected.The operation methods,operation duration,intraoperative blood loss,operation complications,and relief of symptoms were retrospectively analyzed.

Ablation and Inhibition of the Immunoproteasome Catalytic Subunit LMP7 Attenuate Experimental Abdominal Aortic Aneurysm Formation in Mice.

Low-molecular mass protein 7 (LMP7) is a proteolytic subunit of the immunoproteasome that is involved in regulating inflammatory responses. However, the role of LMP7 in the pathogenesis of abdominal aortic aneurysm (AAA) remains unknown. In this study, ApoE knockout (KO) or LMP7/ApoE double KO (dKO) mice were infused with angiotensin II (Ang II, 1000 ng/kg per minute) for up to 28 d.

Role of Family with Sequence Similarity 3A in High Glucose-induced Oxidative Damage of Human Umbilical Vein Endothelial Cells.

Objective To investigate the role of family with sequence similarity 3A(Fam3A) in high glucose-induced damage of human umbilical vein endothelial cells (HUVECs). Methods HUVECs were divided into control group and high glucose group, which were cultured in endothelial cell medium (ECM) containing 5.5 mmol/L of glucose and ECM containing 33.

GLP-1 and Ghrelin Attenuate High Glucose/High Lipid-Induced Apoptosis and Senescence of Human Microvascular Endothelial Cells.

Background/aims: GLP-1 and ghrelin are common appetite-regulating hormones. Both have multiple functions beyond metabolic regulation. However, the effects of GLP-1 and ghrelin on endothelial biology are not fully understood.
