Webultraviolet-visible (UV-Vis) spectrum. In this paper, the shifts of UV-Vis spectrum of quercetin in aqueous ethanol solution with different pH values were investigated. The UV-Vis spectrum of quercetin in 50% (v/v) aqueous ethanol solution showed two characteristic adsorption bands setting at 374 nm and 256 nm, respectively. When the pH value WebApr 13, 2024 · Prenatal ethanol exposure is associated with neurodevelopmental defects and long-lasting cognitive deficits, which are grouped as fetal alcohol spectrum disorders (FASD). The molecular mechanisms underlying FASD are incompletely characterized. Alternative splicing, including the insertion of microexons (exons of less than 30 …
