Special Issue Information

Dear Colleagues,

Oxidative stress is involved in vascular diseases such as hypertension, atherosclerosis, aortic aneurysm, and aortic dissection. Oxidative stress is a state in which reactive oxygen species (ROS) are more than their antioxidant activity. ROS are produced in blood vessels mainly by the mitochondrial electron transfer system, NAD(P)H oxidase, xanthine oxidase, and uncoupling of nitric oxide synthase. ROS act on various tissues, including vascular endothelial, smooth muscle, and perivascular tissues. However, because the half-life of ROS is generally short, it is unlikely that ROS act over a wide area, and local redox balance must be considered. Furthermore, physiological amounts of ROS act as messengers in the signal transduction pathway, and redox signaling regulates gene expression, cell proliferation, migration, and cell death, making the pathogenesis complex and therapeutic intervention difficult. In fact, numerous clinical trials have been conducted to inhibit ROS with the aim of reducing oxidative stress. Still, unfortunately, no evidence of the efficacy of antioxidant therapy has been demonstrated in humans.

This Special Issue aims to stimulate discussion and highlight the latest developments in how oxidative stress acts on vascular disease. A comprehensive understanding of the effects of ROS on blood vessels will assist in developing new therapeutic strategies and drugs for vascular disease. The journal welcomes review articles and original research papers addressing all relevant basic and clinical topics in the above areas.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Antioxidants is an international peer-reviewed open access monthly journal published by MDPI.

Background: Maternal physiological hypercholesterolemia (MPH) occurs in pregnancy for a proper fetal development. When cholesterol increases over the physiological range, maternal supraphysiological hypercholesterolemia (MSPH) is described, a condition underdiagnosed by a lack of evidence showing its biological and clinical relevance.

Background: Maternal physiological hypercholesterolemia (MPH) occurs in pregnancy for a proper fetal development. When cholesterol increases over the physiological range, maternal supraphysiological hypercholesterolemia (MSPH) is described, a condition underdiagnosed by a lack of evidence showing its biological and clinical relevance. Aim: To determine if MSPH associates with maternal vascular dysfunction, along with changes in the composition and function of maternal HDL leading to increased cardiovascular risk. Methods: This study included 57 women at term of pregnancy in which a lipid profile was determined. Results: Maternal total cholesterol (TC) and LDL but not HDL were increased in MSPH women. The isolated HDL from a subgroup of MSPH women had a lower protein abundance and a reduced activity of the antioxidant enzyme PON1; however, an increased antioxidant capacity compared to MPH was observed, along with higher serum levels of α-tocopherol. Moreover, HDL from a subgroup of MSPH women had a lower capacity to induce NO synthesis in endothelial cells compared to MPH. In the circulation, we observed a reduced total antioxidant capacity and augmented levels of soluble VCAM, ApoB, ApoCII, ApoCIII, IL-10, and IL-12p70, as well as the cardiovascular risk ratio ApoB/ApoAI, compared to MPH women. Conclusion: MSPH women present dysfunctional HDL and increased atherogenic cardiovascular risk factors. Full article
