Epicatechin Influence on Biochemical Modification of Human Erythrocyte Metabolism and Membrane Integrity.

Red blood cells (RBCs) are the main cells of the blood, perform numerous functions within the body and are in continuous contact with endogenous and exogenous molecules. In this context, the study aims to investigate the effect of epicatechin (EC) (flavan-3-ols) on the erythrocytes, analyzing the protective effect of the molecule and the action exerted on metabolism and RBC membrane. The effect of EC on RBC viability has been evaluated through the change in hemolysis and methemoglobin, assessing caspase 3 activity and performing a cytofluorometric analysis.

Novel Bioplastic Based on PVA Functionalized with Anthocyanins: Synthesis, Biochemical Properties and Food Applications.

Over the last ten years, researchers' efforts have aimed to replace the classic linear economy model with the circular economy model, favoring green chemical and industrial processes. From this point of view, biologically active molecules, coming from plants, flowers and biomass, are gaining considerable value. In this study, firstly we focus on the development of a green protocol to obtain the purification of anthocyanins from the flower of , based on simulation and on response surface optimization methodology.

Mechanisms Underlying the Effects of Chloroquine on Red Blood Cells Metabolism.

Chloroquine (CQ) is a 4-aminoquinoline derivative largely employed in the management of malaria. CQ treatment exploits the drug's ability to cross the erythrocyte membrane, inhibiting heme polymerase in malarial trophozoites. Accumulation of CQ prevents the conversion of heme to hemozoin, causing its toxic buildup, thus blocking the survival of Plasmodium parasites.

A case report on the physiological responses to extreme heat during Sicily's July 2023 heatwave.

July 2023 has been confirmed as Earth's hottest month on record, and it was characterized by extraordinary heatwaves across southern Europe. Field data collected under real heatwave periods could add important evidence to understand human adaptability to extreme heat. However, field studies on human physiological responses to heatwave periods remain limited.
