Peanut sk.ns are regarded as a low economic value by-product of the peanut industry;however, they contain high levels of bioactive compounds including catechins and procyanidins, which are k.own for their health-promoting properties. The in vitro antioxidant activity of peanut sk.n extracts (PSE) has been reported but the associated anti-inflammatory properties have not been widely examined. This study investigated the anti-inflammatory effects of PSE on the pro-inflammatory enzyme, Cyclooxygenase-2 (COX-2) protein expression, on its downstream product, prostaglandin E2 (PGE2), and on nitrous oxide (NO) levels. Defatted peanut sk.ns were extracted using two aqueous solvent mixtures (50% acetone and 90% ethanol), in order to compare the effects of the two solvent systems on antioxidant and anti-inflammatory properties. PSE antioxidant activity was determined by the hydrophilic oxygen radical absorbance capacity (H-ORAC) assay, while total phenolics were determined by the Folin-Ciocalteu assay and flavan-3-ols and procyanidins were quantified by HPLC. Acetone extracted PSE (A-PSE) exhibited numerically, but not statistically higher H-ORAC and total phenolic values than the ethanol extracted PSE (E-PSE) (1836 μmol Trolox/100 g and 67.9 mg GAE/g, and 1830 μmol Trolox/100 g and 51.8 GAE/g respectively). A-PSE also had higher levels of flavan-3-ols and procyanidins than E-PSE. RAW 264.7 cells were pretreated with 1.0%, 2.5% and 5.0% (v/v) of A-PSE or E-PSE and induced with the inflammatory mark.r, lipopolysaccharide (LPS) for 12 hours. COX-2 protein expression, measured by Western blotting was significantly (p 2 and NO levels measured by ELISA, were significantly (p < 0.05) decreased with increasing added levels of A-PSE and E-PSE suggesting that A-PSE and E-PSE not also possess similar antioxidant properties, but also exhibit similar anti-inflammatory effects.

根据《国际卫生条例(2005)》(IHR),世界卫生组织(WHO)宣布将新型冠状病毒肺炎(COVID-19)列为国际关注的突发公共卫生事件。系统性问题导致此次病毒暴发,该疫情全世界大流行对全球政治和社会系统产生了重大影响。虽然过去15年间科学界在提高了公众对于疾病大流行的警觉方面做了大量的工作,但此次疫情依然暴发并已威胁全球人们的健康,影响经济发展。为了更好地应对这一事件,降低风险,有哪些做法可以改进?对政府、学术组织和个人有哪些科学建议?本文探讨在如何保障人民健康安全的同时,降低经济和社会成本,并号召世界科学家参加"未来地球健康领域知识行动网络"计划。
