Int Immunopharmacol 2022 Jun 24;110:108938. Epub 2022 Jun 24.

Department of Cardiology, The Second Affiliated Hospital of Nanchang University, Nanchang, 330006, China. Electronic address:

The immune response is of great significance in the initiation and progression of a diversity of cardiovascular diseases involving pro-and anti-inflammatory cytokines. Interleukin-35 (IL-35), a cytokine of the interleukin-12 family, is a novel anti-inflammation and immunosuppressive cytokine, maintaining inflammatory suppression and regulating immune homeostasis. The role of IL-35 in cardiovascular diseases (CVDs) has aroused enthusiastic attention, a diversity of experimental or clinical evidence has indicated that IL-35 potentially has a pivot role in protecting against cardiovascular diseases, especially atherosclerosis and myocarditis.

miRNA Regulatory Networks Associated with Peripheral Vascular Diseases.

J Clin Med 2022 Jun 16;11(12). Epub 2022 Jun 16.

Chair and Department of Biology and Genetics, Medical University of Lublin, 4a Chodźki St., 20-093 Lublin, Poland.

A growing body of evidence indicates a crucial role of miRNA regulatory function in a variety of mechanisms that contribute to the development of diseases. In our previous work, alterations in miRNA expression levels and targeted genes were shown in peripheral blood mononuclear cells (PBMCs) from patients with lower extremity artery disease (LEAD), abdominal aortic aneurysm (AAA), and chronic venous disease (CVD) in comparison with healthy controls. In this paper, previously obtained miRNA expression profiles were compared between the LEAD, AAA, and CVD groups to find either similarities or differences within the studied diseases. Read More

Gene Expression Profiling in Abdominal Aortic Aneurysms.

J Clin Med 2022 Jun 7;11(12). Epub 2022 Jun 7.

Department of Vascular and Endovascular Surgery, University Hospital of Heidelberg, 69120 Heidelberg, Germany.

Gene expression profiling of abdominal aortic aneurysms (AAA) indicates that chronic inflammatory responses, active matrix metalloproteinases, and degradation of the extracellular matrix components are involved in disease development and progression. This study investigates intra- and interpersonal RNA genome-wide expression profiling differences (Illumina HumanHT-12, BeadCHIP expression) of 24 AAA biopsies from 12 patients using a single gene and pathway (GeneOntology, GO enrichment) analysis. Biopsies were collected during open surgical AAA repair and according to prior finite element analysis (FEA) from regions with the highest and lowest wall stress. Read More

Embolization for Type Ia Endoleak after EVAR for Abdominal Aortic Aneurysms: A Systematic Review of the Literature.

Biomedicines 2022 Jun 18;10(6). Epub 2022 Jun 18.

Department of Vascular and Endovascular Surgery, University Hospital Münster, 48149 Münster, Germany.

(1) Successful endovascular repair for abdominal aortic aneurysms is based on the complete exclusion of the aneurysm sac from the systemic circulation. Type Ia endoleak (ELIA) is defined as the persistent perfusion of the aneurysm sac due to incomplete proximal sealing between aorta and endograft, with a consequent risk of rupture and death. Endoleak embolization has been sporadically reported as a viable treatment for ELIA. Read More

The pulsatile 3D-Hemodynamics in a doubly afflicted human descending abdominal artery with iliac branching.

Comput Methods Biomech Biomed Engin 2022 Jun 21:1-20. Epub 2022 Jun 21.

Department of Cardiology, Institute of Medical Science, BHU, Varanasi, Uttar Pradesh, India.

The study of patient-specific human arterial flow dynamics is well known to face challenges like a) apt geometric modelling, b) bifurcation zone meshing, and c) capturing the hemodynamic prone to variations with multiple disease complications. Due to aneurysms and stenosis in the same arterial network, the blood flow dynamics get affected, which needs to be explored. This study develops a new protocol for accurate geometric modelling, bifurcation zone meshing and numerically investigates the arterial network with abdominal aortic aneurysms (AAA) and right internal iliac stenosis (RIIAS).

[Fenestrated and branched endovascular aortic prostheses : An update].

Radiologie (Heidelb) 2022 Jun 20. Epub 2022 Jun 20.

Abteilung für Kardiovaskuläre und Interventionelle Radiologie, Universitätsklinik für Radiologie und Nuklearmedizin, Medizinische Universität Wien, Währinger Gürtel 18-20, 1090, Wien, Österreich.

Background: Today, complex abdominal aortic pathologies involving the visceral arteries and without an adequate proximal neck can be treated using fenestrated/branched endovascular aortic repair (FEVAR/BEVAR) with similar safety and success rates as infrarenal aortic pathologies treated with tubular EVAR.

Methodical Innovations And Challenges: Fenestrations (if the vessel originates from a nondilated aorta) or branches (if the vessel originates from a dilated aorta) may be used for the visceral arteries. Both types of openings are sealed via bridging stent grafts that connect to the target vessel. Read More
