Effects of environmental enrichment on GLUT expression in the visual cortex of amblyopic rats.

Objective: To investigate the potential changes of glucose metabolism and glucose transporter protein (GLUT) in the visual cortex of formally deprived amblyopic rats, as well as the effects of enriched environments on the levels of nerve conduction and glucose metabolism in the visual cortex of amblyopic rats.

Methods: 36 rats were randomly divided into three groups: CON + SE (n = 12), MD + SE (n = 12) and MD + EE (n = 12). The right eyelids of both MD + SE and MD + EE groups were sutured.

Recent-year variations in O pollution with high-temperature suppression over central China.

By analyzing environmental and meteorological monitoring data over recent years of 2015-2022, the Twain-Hu Basin (THB) in central China was identified as a regional O pollution center over China with the highest increasing trend at 1.10 %⸱yr in interannual variations of O concentrations with deteriorating O pollution over recent years. We explored the spatiotemporal variations in O pollution in the THB with ozone suppression (OS) under high air temperature over metropolitan, small urban, and mountainous areas.

Interannual variations in ozone pollution with a dipole structure over Eastern China associated with springtime thermal forcing over the Tibetan Plateau.

The Tibetan Plateau (TP) is essential in modulating climate change in downstream Eastern China (EC). As a meteorology-sensitive pollutant, changes in ozone (O) in connection with the TP have received limited attention. In this study, using climate analysis of the China High Air Pollutants O product and ERA5 reanalysis data of meteorology for 1980-2020, the effect of springtime TP thermal forcing on the warm season (April-September) O pollution over EC was investigated.

Seasonal changes in the recent decline of combined high PM and O pollution and associated chemical and meteorological drivers in the Beijing-Tianjin-Hebei region, China.

China suffers from combined air pollution (CAP) comprising dual high O and PM, particularly in the Beijing-Tianjin-Hebei (BTH) region, which is an urban agglomeration in the North China Plain. To characterize the seasonal changes in regional CAP, 82 CAP days were identified during the study period from 2015 to 2019 with the co-occurring pollution of O and PM in the BTH. It is found that CAP seasonality has undergone distinct changes with a declining trend in the interannual variations in CAP over recent years.
