微塑料作为水体中一种普遍存在的污染物已引起社会的广泛关注.为探究微塑料在淡水河流中的时空分布特征及其迁移规律,以长江支流香溪河为例,分别在2020年11月和2021年4月对香溪河表层水体、沉积物和消落带进行取样分析.结果表明,香溪河表层水体中微塑料的平均丰度为(6.64±1.32)n·L^(-1)(平水期)和(5.00±1.07)n·L^(-1)(枯水期),沉积物中微塑料的平均丰度为(0.56±0.13)n·g^(-1)(平水期)和(0.41±0.09)n·g^(-1)(枯水期),消落带中微塑料的平均丰度为(0.53±0.15)n·g^(-1)(平水期)和(0.68±0.18)n·g^(-1)(枯水期),表层水体、沉积物和消落带中微塑料丰度分布存在显著差异性(P<0.05).在表层水体和沉积物中微塑料粒径主要分布在0.1~0.5 mm,消落带中主要分布在1~5 mm;表层水体和消落带中微塑料颜色以透明为主,沉积物中以蓝色为主;香溪河流域微塑料的形态以纤维为主,材质主要是聚乙烯(PE)和聚丙烯(PP).影响微塑料分布的因素较多,分析结果表明,表层水体中微塑料丰度与水体流速呈负相关;沉积物中微塑料丰度与河床底质类型有关,与底质粒径呈负相关.结合各个采样点位的微塑料丰度数据,发现香溪河微塑料在流域空间分布上存在明显迁移过程:沿河纵向主要表现为表层水体中微塑料顺河流方向的纵向迁移,垂直方向上表现为水体与消落带、水体与沉积物的相互迁移.

Neuroprotective Effects of MIP-15 Peptide from Morchella importuna Against Ischemic-Hypoxic Brain Damage in Rats

引用

Food Science and Human Wellness 2024年

作者： Chuan xiong Ping Li Qiang Luo Chia wei Phan Xin Jin Wenli Huang Biotechnology and Nuclear Technology Research Institute， Sichuan Academy of Agricultural Sciences The Second Affiliated Hospital， Chongqing Medical University Department of Anatomy， Faculty of Medicine， Universiti Malaya

Hypoxic-ischemic encephalopathy (HIE) is a prominent cause of neuronal damage and neonatal death， and effective treatment strategies remain limited. In a prior investigation， we purified a novel peptide (designated MIP-15) from the rare mushroom Morchella importuna， demonstrating its notable free radical scavenging activity. Nevertheless， the potential neuroprotective role of MIP-15 in neonatal hypoxic-ischemic brain damage (HIBD) and its underlying mechanism remain elusive. The purpose of this study was to evaluate whether MIP-15 exerts neuroprotective effects by inhibiting the mitochondrial apoptotic pathway after HIBD. A HIBD model in 7-day-old (P7) rats was established by the Rice–Vannucci method to evaluate the effect of MIP-15 on the neurological damage severity and space cognitive ability of rats. Subsequently， an oxygen glucose deprivation/reoxygenation (OGD/R) model was established in rat primary hippocampal neurons to explore the mechanism of MIP-15 action. Both in vivo and in vitro data showed that MIP-15 markedly restored endogenous antioxidative activity， decreased brain water content， and ameliorated pathological abnormalities following HIBD. The spatial cognitive ability and motor function of HIBD rats were also repaired. Moreover， in primary hippocampal neurons after OGD/R， MIP-15 increased cell viability by inhibiting the mitochondrial-dependent apoptosis pathway， as manifested by stabilization of the mitochondrial membrane potential， prevention of the release of cytochrome c， upregulation of Bcl-2/Bax， and reduction in the triggering of caspase proteins. These data indicate that MIP-15 may have the potential to act as a neuroprotective agent.
