Emerging role of miRNAs in the regulation of ferroptosis
Front Mol Biosci. 2023 Feb 15;10:1115996. doi: 10.3389/fmolb.2023.1115996. eCollection 2023.ABSTRACTFerroptosis is a kind of cell death which has distinctive features differentiating it from autophagy, necrosis and apoptosis. This iron-dependent form of cell death is described by an increase in lipid reactive oxygen species, shrinkage of mitochondria and decrease in mitochondrial cristae. Ferroptosis is involved in the initiation and progression of many diseases and is regarded as a hotspot of investigations on treatment of disorders. Recent studies have shown that microRNAs partake in the regulation of ferroptosis. The im...

Low serum albumin: A neglected predictor in patients with cardiovascular disease
Eur J Intern Med. 2022 May 7:S0953-6205(22)00181-9. doi: 10.1016/j.ejim.2022.05.004. Online ahead of print.ABSTRACTAlbumin, the most abundant circulating protein in blood, is an essential protein which binds and transports various drugs and substances, maintains the oncotic pressure of blood and influences the physiological function of the circulatory system. Albumin also has anti-inflammatory, antioxidant, and antithrombotic properties. Evidence supports albumin's role as a strong predictor of cardiovascular (CV) risk in several patient groups. Its protective role extends to those with coronary artery disease, heart failu...

Comparison of Serum Selenium Levels Between Patients with Newly Diagnosed Atrial Fibrillation and Normal Controls
Biol Trace Elem Res. 2022 May 9. doi: 10.1007/s12011-022-03281-9. Online ahead of print.ABSTRACTAtrial fibrillation (AF) is the most common sustained dysrhythmia in the elderly population. It is estimated to affect more than 30 million people worldwide. AF occurs when abnormal electrical impulses start to activate in the atria and override the heart's natural pacemaker, which can no longer control the heart's rhythm. Since atrial contractility is impaired in AF, blood flow in the atria becomes stasis over time and causes thrombus formation. This thrombus causes the risk of embolism and causes complications such as stroke. ...

Serum albumin and cardiovascular disease: State-of-the-art review.
Abstract Cardiovascular disease is the leading cause of death worldwide. Conceptually, endothelial dysfunction, inflammatory conditions and oxidative stress are at the forefront of the onset and development of most cardiovascular diseases, particularly coronary artery disease and heart failure. Serum albumin has many physiological properties, including in particular antioxidant, anti-inflammatory, anticoagulant and anti-platelet aggregation activity. It also plays an essential role in the exchange of fluids across the capillary membrane. Hypoalbuminemia is a powerful prognostic marker in the general population as ...

Icosapent Ethyl: drug profile and evidence of reduced residual cardiovascular risk in patients with statin-managed LDL-C cholesterol.
Authors: Bazarbashi N, Miller M Abstract INTRODUCTION: Icosapent Ethyl (IPE) is a highly purified (>96%) form of eicosapentanoic acid, a marine-derived omega-3 fatty acid known to reduce serum triglyceride levels. Experimental and human studies also support anti-atherosclerotic properties of IPE including antioxidant, anti-inflammatory, endothelial and plaque stabilizing effects. In the Reduction of Cardiovascular Events with Icosapent Ethyl-Intervention Trial (REDUCE-IT)l),the addition of 4 grams IPE daily resulted in a 25% reduction in cardiovascular events beyond statins and other standard of care therapies. ...

Uric acid and cardiovascular disease
Publication date: September 2018Source: Clinica Chimica Acta, Volume 484Author(s): Gjin NdrepepaAbstractUric acid (UA) is an end product of purine metabolism in humans and great apes. UA acts as an antioxidant and it accounts for 50% of the total antioxidant capacity of biological fluids in humans. When present in cytoplasm of the cells or in acidic/hydrophobic milieu in atherosclerotic plaques, UA converts into a pro-oxidant agent and promotes oxidative stress and through this mechanism participates in the pathophysiology of human disease including cardiovascular disease (CVD). Most epidemiological studies but not all of ...
