Vascular endothelial cell specification in health and disease.

Angiogenesis 2021 Apr 12. Epub 2021 Apr 12.

Department of Cell Biology, University of Virginia School of Medicine, Charlottesville, VA, 22908, USA.

There are two vascular networks in mammals that coordinately function as the main supply and drainage systems of the body. The blood vasculature carries oxygen, nutrients, circulating cells, and soluble factors to and from every tissue. The lymphatic vasculature maintains interstitial fluid homeostasis, transports hematopoietic cells for immune surveillance, and absorbs fat from the gastrointestinal tract. Read More

Current Status of Angiogenic Cell Therapy and Related Strategies Applied in Critical Limb Ischemia.

Int J Mol Sci 2021 Feb 26;22(5). Epub 2021 Feb 26.

Biomedicine, Biotechnology and Public Health Department, Cádiz University, 11519 Cadiz, Spain.

Critical limb ischemia (CLI) constitutes the most severe form of peripheral arterial disease (PAD), it is characterized by progressive blockade of arterial vessels, commonly correlated to atherosclerosis. Currently, revascularization strategies (bypass grafting, angioplasty) remain the first option for CLI patients, although less than 45% of them are eligible for surgical intervention mainly due to associated comorbidities. Moreover, patients usually require amputation in the short-term. Read More

Drug-eluting embolic microspheres: State-of-the-art and emerging clinical applications.

Expert Opin Drug Deliv 2021 Mar 22;18(3):383-398. Epub 2021 Jan 22.

Center for Interventional Oncology, Radiology and Imaging Sciences, Clinical Center, National Institutes of Health, Bethesda, MD, USA.

Introduction: Drug-eluting embolic (DEE) microspheres, or drug-eluting beads (DEB), delivered by transarterial chemoembolization (TACE) serve as a therapeutic embolic to stop blood flow to tumors and a drug delivery vehicle. New combinations of drugs and DEE microspheres may exploit the potential synergy between mechanisms of drug activity and local tissue responses generated by TACE to enhance the efficacy of this mainstay therapy.

Areas Covered: This review provides an overview of key drug delivery concepts related to DEE microspheres with a focus on recent technological developments and promising emerging clinical applications as well as speculation into the future. Read More

Pulmonary sequestration: What the radiologist should know.

Clin Imaging 2021 May 3;73:61-72. Epub 2020 Dec 3.

Diagnostic and Interventional Radiology, Department of Translational Research, University of Pisa, Via Roma, 67, 56126 Pisa, Italy.

Pulmonary sequestration consists of a nonfunctioning mass of lung tissue, either sharing the pleural envelope of the normal lung (intralobar) or with its own pleura (extralobar), lacking normal communication with the tracheobronchial tree and receiving its arterial supply by one or more systemic vessels. It is the second most common congenital lung anomaly according to pediatric case series, but its real prevalence is likely to be underestimated, and imaging plays a key role in the diagnosis and treatment management of the condition and its potential complications. We will give a brief overview of the pathophysiology, clinical presentation and imaging findings of intra- and extralobar pulmonary sequestration, with particular reference to multidetector computed tomography as part of a powerful and streamlined diagnostic approach.

Limits and pitfalls of indirect revascularization in moyamoya disease and syndrome.

Neurosurg Rev 2020 Sep 21. Epub 2020 Sep 21.

Department of Neurosurgery, IRCCS Istituto Giannina Gaslini, Via Gerolamo Gaslini, Genoa, Italy.

Moyamoya vasculopathy is a rare chronic cerebrovascular disorder characterized by the stenosis of the terminal branches of the internal carotid arteries and the proximal tracts of anterior and middle cerebral arteries. Although surgical revascularization does not significantly change the underlying pathogenic mechanisms, it plays a pivotal role in the management of affected individuals, allowing to decrease the risk of ischemic and hemorrhagic complications. Surgical approaches may be direct (extracranial-intracranial bypass), indirect, or a combination of the two. Read More

Authors:
Takuya Watanabe

Vasa 2021 Apr 14;50(3):165-173. Epub 2020 Sep 14.

Department of Internal Medicine, Ushioda General Hospital/Clinic, Yokohama, Japan.

This review provides an updated overview of the emerging roles of neopterin derivatives in atherosclerosis. Neopterin, a metabolite of guanosine triphosphate, is produced by interferon-γ-activated macrophages and is expressed at high levels in atheromatous plaques within the human carotid and coronary arteries as well as in the aorta. Plasma concentrations of neopterin are higher in patients with carotid, cerebral, and coronary artery diseases as well as aortic aneurysm. Read More

Department of Hand and Reconstructive Microsurgery, National University Health System, Level 11, Tower Block 1E Kent Ridge Road, Singapore 119228, Singapore. Electronic address:

The vascular supply of the hand and wrist is derived from the radial and ulnar arteries. This forms a complex network of vessels on the palmar and dorsal surfaces of the hand. Anastomoses and branching patterns of vessels at the level of the carpals, metacarpals, and phalanges form the basis of old and new flap designs. Read More

The cingulate cortex in neurologic diseases: History, Structure, Overview.

Authors:
Brent A Vogt

Handb Clin Neurol 2019 ;166:3-21

Cingulum Neurosciences Institute, Manlius, NY, United States; Department of Anatomy and Neurobiology, Boston University School of Medicine, Boston, MA, United States.

A brief review of the history of key observations of cingulate organization, particularly in the limbic system framework, is presented from 1907 to the present. The reasons why it has not played a significant role in neurology reflect the fact that its arterial supply is complex and no cingulate syndrome has been identified. A flat map of its eight subregions and areas is presented as a basis for many subsequent chapters in this volume. Read More

MicroRNAs in Uteroplacental Vascular Dysfunction.

Cells 2019 10 29;8(11). Epub 2019 Oct 29.

Lawrence D. Longo MD Center for Perinatal Biology, Division of Pharmacology, Department of Basic Sciences, Loma Linda University School of Medicine, Loma Linda, California 92350, USA.

Pregnancy complications of preeclampsia and intrauterine growth restriction (IUGR) are major causes of maternal and perinatal/neonatal morbidity and mortality. Although their etiologies remain elusive, it is generally accepted that they are secondary to placental insufficiency conferred by both failure in spiral artery remodeling and uteroplacental vascular malfunction. MicroRNAs (miRNAs) are small no-coding RNA molecules that regulate gene expression at the post-transcriptional level. Read More

Current management strategies for visceral artery aneurysms: an overview.

Surg Today 2020 Jan 16;50(1):38-49. Epub 2019 Oct 16.

Department of Surgery, Keio University School of Medicine, 35 Shinanomachi, Shinjuku-ku, Tokyo, 160-8582, Japan.

Visceral artery aneurysms (VAAs) are rare and affect the celiac artery, superior mesenteric artery, and inferior mesenteric artery, and their branches. The natural history of VAAs is not well understood as they are often asymptomatic and found incidentally; however, they carry a risk of rupture that can result in death from hemorrhage in the peritoneal cavity, retroperitoneal space, or gastrointestinal tract. Recent advances in imaging technology and its availability allow us to diagnose all types of VAA. Read More

Klinik für Innere Medizin III, Kardiologie, Angiologie und Internistische Intensivmedizin, Universitätsklinikum des Saarlandes, Saarland University, Homburg/Saar, Germany.

Arterial hypertension is associated with increased cardiovascular morbidity and mortality. Although blood pressure-lowering therapies significantly reduce the risk of major cardiovascular events, blood pressure control remains unsatisfactorily low. Several device-based antihypertensive therapies have been investigated in patients with treatment-resistant hypertension and in patients unable or unwilling to adhere to antihypertensive medication.
