HPV Infection Affects Human Sperm Functionality by Inhibition of Aquaporin-8

Cells, 2020
Human sperm cells express different aquaporins (AQPs), AQP3, 7, 8, 11, which are localized both in the plasma membrane and in intracellular structures. Besides cell volume regulation and end stage of cytoplasm removal during sperm maturation, the role of

Analysis of the evolution trends and influential factors of bankfull discharge in the Lower Yellow River

Scientific Reports, 2022
After the Xiaolangdi Reservoir (XLDR) was put into operation, new water and sediment conditions have improved the silting condition of the Lower Yellow River (LYR), but against this background, the flow capacity of the LYR has become more complex.
