Summary: By developing DNAzyme-based fluorescent turn-on sensors, we can selectively visualize either Fe2+ or Fe3+, revealing a decreased Fe3+/Fe2+ ratio during ferroptosis and an increased Fe3+/Fe2+ ratio in Alzheimer's disease mouse brain. The elevated Fe3+/Fe2+ ratio was mainly observed in amyloid plaque regions, suggesting a correlation between amyloid plaques and the accumulation of Fe3+ and/or conversion of Fe2+ to Fe3+. Our sensors can provide deep insights into the biological roles of labile iron redox cycling.

Summary: Iron dysmetabolism is common in heart failure patients, especially those with reduced ejection fraction. Chronic hypertension, a common risk factor for heart failure and death, is associated with iron deficiency. Iron deposition in organs can cause oxidative stress and cell death. In a rat model of cardiac hypertrophy induced by pressure overload, iron chelation with deferiprone reduced inflammation, lipid peroxidation, mitochondrial iron levels, and hypertrophy. This suggests that iron redistribution, particularly in mitochondria, may have beneficial effects in the cardiovascular system.

Summary: Cardiovascular disease (CVD) is a major cause of morbidity and mortality worldwide, with myocardial infarction caused by atherosclerosis being a leading cause of death in CVD. Ferroptosis, a newly identified form of regulated cell death characterized by iron-dependent accumulation of lipid hydroperoxides, appears to play a role in CVD, exhibiting distinct features from apoptosis, necrosis, and autophagy. The review summarized recent progress on ferroptosis in CVD and atherosclerosis, emphasizing the role of free radical lipid peroxidation (LPO) and discussing the evidence and challenges in this field.

Summary: This study suggests that vascular complications in patients with beta-thalassemia are associated with oxidative modification of lipoproteins. The modification of lipid components may alter lipid peroxidation rate and products. Core lipids and cholesteryl esters levels determine the rate and total production of L center dot. Overall, lipoproteins in beta-thalassemia patients are more susceptible to lipid peroxidation.

Summary: This study tested the effect of Cyamopsis tetragonoloba seed extract on the antioxidant activity of several known dietary flavonoids and non-flavonoid phenolics. The results showed that the seed extract could enhance the antioxidant activity of epigallocatechin gallate (EGCG) at lower concentrations, and significantly reduce oxidative stress in cell culture compared to individual phytochemical treatments. Analysis also revealed previously unreported metabolites that may explain the antioxidant-enhancing effect of the seed extract. The findings of this study are important for the development of effective nutraceutical/dietary supplements.

Summary: The molecular self-diffusion coefficients of microcrystalline cellulose in different solvent systems were measured using pulsed field gradient stimulated echo NMR. The results showed that TBA+ ions can bind to cellulose within a certain range and the binding of DMSO, TBAH, and water to cellulose increases with cellulose concentration. This interaction between TBAH and cellulose leads to steric hindrance between cellulose chains.

Summary: Diet plays a crucial role in the health and well-being of livestock animals. The use of valuable feed additives from by-products can promote circular economy and functional diets. Lignin from sugarcane bagasse has been identified as a potential prebiotic additive for chicken feed, showing positive effects on pellet quality and microbial contamination. Particularly, lignin supplementation in mash feed has a higher prebiotic potential for promoting the growth of Bifidobacterium. This study suggests that lignin from sugarcane bagasse can be a sustainable and eco-friendly alternative for chicken feed additives.

Summary: This study evaluated the use of greener precipitating agents (methane sulfonic acid, formic acid, and lactic acid) to produce lignin bioactive extracts from sugarcane bagasse and straw alkaline black liquors, replacing sulfuric acid commonly used in industry. The highest precipitation yield was achieved with lactic acid for sugarcane bagasse. The composition of the extracts varied between sulfuric acid and greener precipitating agents, particularly in terms of sugar content. The results suggest organic acids, especially formic acid, as promising alternatives to recover lignin bioactive extracts instead of conventional sulfuric acid.

Summary: Nanoemulsions can be produced using simple methods and compounds from natural sources. These nanoemulsions have the potential to improve the dispersibility and bioavailability of active ingredients in the skin. In this study, oil-in-water nanoemulsions with and without vitamin E were formulated and evaluated for their stability, microstructure, droplet size, color attributes, encapsulation efficiency, UV photostability, antioxidant activity, and in vitro permeation. The results showed that the nanoemulsions were highly stable, with small droplet sizes. The topical nano cream containing vitamin E demonstrated protective effects against UV degradation and exhibited significant antioxidant activity. Moreover, the formulations efficiently delivered vitamin E into the skin.

Summary: Expenditure isolation of lignin and the understanding of its structural variations during different isolation processes are crucial for the high-value utilization of lignin. This study proposed a green deep eutectic solvent (DES) consisting of choline chloride, ethylene glycol, and 4-chlorobenzene sulfonic acid for rapid lignin separation from poplar. The structural variations of DES lignin and its relationship with alkali pre-extraction of hemicellulose were investigated. The results showed that alkali pretreatment enhanced the DES separation of lignin and promoted the cleavage of specific linkages, resulting in reduced molecular weight and thermal stability of isolated DES lignin. Moreover, DES lignin obtained from integrated utilization displayed higher purity and S/G ratio compared to lignin obtained from direct DES treatment.
