Brain white matter abnormalities associated with copy number variants.

White matter (WM) signal abnormalities are demonstrated in various neurodevelopmental disorders on brain magnetic resonance imaging (MRI). The pattern of WM abnormalities can aid in the diagnostic process. This study aims to characterize the WM changes found in microdeletion/microduplication syndromes.

Mating-increases trypsin in female Drosophila hemolymph.

Male-derived accessory gland proteins (Acps) are transferred to the female reproductive tract during mating and affect female reproductive maturation and behavior. Some Acps subsequently enter the female hemolymph. We hypothesized that humoral proteases are the primary effectors of Acp bioactivity by processing (activating) and/or degrading them.
