Taken together, this investigation indicates the potent neuroprotective and antioxidative efficiencies of Camellia sinensis against arsenic-induced oxidative threat.
Theoretical investigations on the micellization of mixtures of (i) amino acid‐based anionic surfactants [AAS: N‐dodecyl derivatives of aminomalonate, −aspartate, and ‐glutamate] and (ii) hexadecyltrimethylammonium bromide (HTAB), were carried out at different mole ratios. Variation in the theoretical values of critical micelle concentration (CMC), mole fraction of surfactants in the micellar phase (X), at the interface (Xσ), interaction parameters at the bulk/interface (βR/βσ), ideality/nonideality of the mixing processes, and activity coefficients (f) were evaluated using Rubingh, Rosen, Motomora, and Sarmoria‐Puvvada‐Blankschtein models. CMC values significantly deviate from the theroretically calculated values, indicating associative interaction. With increasing mole fraction of AAS (αAAS), the magnitude of the (βR/βσ) values gradually decreased, considered to attributable to hydrophobic interactions. With increasing αAAS, the micellar mole fraction of HTAB (X2) decreased insignificantly and X2 values were higher than those compared to AAS for all combinations, due to the dominance of HTAB in micelles. Micellar mole fraction at the ideal state of AAS (X1ideal) differed from micellar mole fraction of AAS (X1), indicating nonideality in the mixed micellization process. Gibbs free energy of micellization (
∆Gm) values are more negative than the free energy of micellization for ideal mixing (∆Gmideal), indicating the micellization process is spontaneous. With increasing αAAS, the enthalpy of micellization (ΔHm) and entropy of micellization (ΔSm) values gradually increased, which indicates micellization is exothermic. The different physicochemical parameters of the mixed micelles are correlated with the variation in the spacer length between the two carboxylate groups of AAS.
Reduction in plasma low-density lipoprotein is a fundamental treatment for the prevention of acute coronary syndromes (ACS). Oxidization of low-density lipoprotein (LDL) particles leads to formation of atherosclerotic lesions and increased risk of cardiovascular disease (CVD) via a complex cascade of biochemical events occurring mostly within the arterial wall. The major advantage of drug those are treating with hypertension, hyperglycemia and hyperlipidemia to reduce the CVD morbidity and mortality are well established. However, the epidemiological evidences support that ingestion of certain foods in regular diet chart results to a reduction in of myocardial infarction markers and other CVD. Many reviews supported that the dietary antioxidants pertained to LDL oxidation and to vascular endothelial dysfunction. Polyphenol consumption is beneficial to maintain the plasma LDL level. This short commentary emphasising on health aspect depending on the published literature, which may provide some guidance for researchers in further investigations of cardiovascular health agents.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
