Effects of marine pollution on the expression of hepatic HSP60 and HSP70 protein in Sebastiscus marmoratus

摘要 热应激蛋白(HeatShockProteins，HSPs)是一种生物体内普遍适用并高度存在的应激蛋白，在外界污染影响下，HSPs的表达量发生变化，能快速保护细胞对抗外源性或内源性应激的攻击，提高细胞的修复能力并增强细胞对付应激的耐受程度。HSPs的诱导被认为是反映环境污染状况最灵敏的生物学反应之一，本文着重研究海洋鱼类HSP60和HSP70蛋白对常见海洋污染物的响应规律，探讨作为生物标志物的可行性。 本研究利用蛋白印迹法测定不同浓度石油水溶性成分(watersolublefraction,WSF)(20μg•L-1、40μg•L-1、80μg•L-...Abstract Heat Shock Proteins (HSPs) is a universal stress proteins in vivo. Under the environmental pollution, changes in the expression of HSPs can quickly protect the cells against exogenous or endogenous stress through increasing the repair capacity of cells and enhancing the tolerance of cell to stresses. Induction of HSPs is considered to be one of the most sensitive biological responses to ...学位：理学硕士院系专业：环境与生态学院_环境科学学号：3312012115165

Measurement of integrated luminosity of data collected at 3.773 GeV by BESIII from 2021 to 2024

We present a measurement of the integrated luminosity e+e- of collision data collected by the BESIII detector at the BEPCII collider at a center-of-mass energy of Ecm = 3.773 GeV. The integrated luminosities of the datasets taken from December 2021 to June 2022, from November 2022 to June 2023, and from October 2023 to February 2024 were determined to be 4.995±0.019 fb-1, 8.157±0.031 fb-1, and 4.191±0.016 fb-1, respectively, by analyzing large angle Bhabha scattering events. The uncertainties are dominated by systematic effects, and the statistical uncertainties are negligible. Our results provide essential input for future analyses and precision measurements
