Redox Epiphospholipidome in Programmed Cell Death Signaling: Catalytic Mechanisms and Regulation.

A huge diversification of phospholipids, forming the aqueous interfaces of all biomembranes, cannot be accommodated within a simple concept of their role as membrane building blocks. Indeed, a number of signaling functions of (phospho)lipid molecules has been discovered. Among these signaling lipids, a particular group of oxygenated polyunsaturated fatty acids (PUFA), so called lipid mediators, has been thoroughly investigated over several decades.

Resolving the paradox of ferroptotic cell death: Ferrostatin-1 binds to 15LOX/PEBP1 complex, suppresses generation of peroxidized ETE-PE, and protects against ferroptosis.

Hydroperoxy-eicosatetraenoyl-phosphatidylethanolamine (HpETE-PE) is a ferroptotic cell death signal. HpETE-PE is produced by the 15-Lipoxygenase (15LOX)/Phosphatidylethanolamine Binding Protein-1 (PEBP1) complex or via an Fe-catalyzed non-enzymatic radical reaction. Ferrostatin-1 (Fer-1), a common ferroptosis inhibitor, is a lipophilic radical scavenger but a poor 15LOX inhibitor arguing against 15LOX having a role in ferroptosis.

Polymorphism of the Oxytocin Receptor (OXTR) Gene Affects the Circulating Oxytocin Receptor Levels in Late-Term Pregnancy in a Turkish Population.

Introduction: Postterm and late-term pregnancies still remain a serious health problem, and underlying exact mechanisms are not fully elucidated. These mechanisms are influenced by many factors.

Objective: The aim of this study was to investigate the relationship between plasma oxytocin and oxytocin receptor levels and oxytocin receptor polymorphisms in term and late-term pregnant women.

Is endocan a biochemical marker for asymptomatic target organ damage in hypertensive patients?

Objective: Identification of the asymptomatic target organ damage (AOD) helps to stratify the overall risk of cardiovascular (CV) diseases and guides a treatment decision in hypertensive patients without a symptomatic CV or renal disease. The endothelial-cell-specific molecule 1 (endocan) is regarded as a novel marker of endothelial dysfunction. Its release is increased in hypertensive patients, especially those with symptomatic CV and renal disease.

The correlation of serum asymmetric dimethylarginine and anti-Müllerian hormone in primary dysmenorrhea.

In this study, we aimed to investigate the association of serum asymmetric dimethylarginine (ADMA) and anti-Müllerian hormone (AMH) levels in primary dysmenorrhea patients. The study employed a cross-sectional design. Eighty-nine female university students with primary dysmenorrhea were included in the study.
