Low Back Pain: A Pain That May Not Be Harmless

European Journal of Case Reports in Internal Medicine, 2018
Abdominal aortic aneurysms are defined as vascular dilatations greater than 50% of the normal proximal segment or those that have a maximum diameter above 3 cm.

Diagnosis and Successful Surgical Treatment of Ascending Aorta Valved Conduit Rupture

Вестник рентгенологии и радиологии, 2022
Prosthetic infection is the most common complication after aortic replacement with a synthetic vascular prosthesis or a valved conduit (VC); in this case, aortic valve (AV) rupture occurs in 0.1-1.3% of patients.

Generation of Patient-specific Structured Hexahedral Mesh of Aortic Aneurysm Wall [PDF]

arXiv, 2022
Abdominal Aortic Aneurysm (AAA) is an enlargement in the lower part of the main artery Aorta by 1.5 times its normal diameter. AAA can cause death if rupture occurs. Elective surgeries are recommended to prevent rupture based on geometrical measurements of AAA diameter and diameter growth rate.

Recent Advancements in Lung Cancer Metastasis Prevention Based on Nanostrategies

Advanced Science, EarlyView.
Metastasis is the leading cause of death in patients with lung cancer. Nanomedicine can be used to prepare efficient drug delivery systems owing to their advantages and plays an important role in the synergistic antimetastasis of lung cancer. This comprehensive review summarizes the emerging nanostrategies against lung cancer metastasis based on the ...

Cardiomyocyte‐Enriched USP20 Ameliorates Pathological Cardiac Hypertrophy by Targeting STAT3 Deubiquitination

Advanced Science, EarlyView.
Cardiomyocyte‐enriched USP20 regulates the K63‐linked ubiquitination of STAT3, and the cardiomyocyte‐specific USP20‐STAT3‐CARM1 axis exerts a protective role in cardiac hypertrophy. Targeting USP20 through cardiac‐specific gene therapy presents a promising strategy for the treatment of cardiac hypertrophy.

Chronic contained rupture of abdominal aortic aneurism complicated with aortic occlusion: a case report

Surgical Case Reports, 2019
Background Chronic contained rupture is a subtype of an abdominal aortic aneurysm rupture. Its diagnosis is sometimes difficult due to lack of typical symptoms.

Comparison of existing aneurysm models and their path forward [PDF]

, 2020
The two most important aneurysm types are cerebral aneurysms (CA) and abdominal aortic aneurysms (AAA), accounting together for over 80\% of all fatal aneurysm incidences. To minimise aneurysm related deaths, clinicians require various tools to accurately estimate its rupture risk. For both aneurysm types, the current state-of-the-art tools to evaluate

Pyruvate Carboxylase in Macrophages Aggravates Atherosclerosis by Regulating Metabolism Reprogramming to Promote Inflammatory Responses Through the Hypoxia‐Inducible Factor‐1 Signaling Pathway

Advanced Science, EarlyView.
This study investigates the role of macrophage pyruvate carboxylase (PC) in atherosclerosis (AS) demonstrating that PC upregulation in macrophages promotes metabolism reprogramming to enhance inflammatory responses via the HIF‐1 signaling pathway.

Emergency department point-of-care ultrasound diagnosis of active bleeding into the intraluminal thrombus of an abdominal aortic aneurysm

Radiology Case Reports, 2023
Rupture of an abdominal aortic aneurysm (AAA) is an immediately life-threatening phenomenon with substantial mortality. Although most AAAs are asymptomatic, an impending AAA rupture can be heralded by nonspecific symptoms and imaging findings on CT and ...

Tensile rupture of medial arterial tissue studied by X-ray micro-tomography on stained samples [PDF]

Journal of the mechanical behavior of biological materials (2018), vol 78, 362-368, 2017
Detailed characterization of damage and rupture mechanics of arteries is one the current challenges in vascular biomechanics, which requires developing suitable experimental approaches. This paper introduces an approach using in situ tensile tests in an X-ray micro-tomography setup to observe mechanisms of damage initiation and progression in medial ...
