Is menstrual cycle-related sialidase activity of the female cervical mucus associated with exosome-like vesicles?
Female cervical mucus contains an endogenous menstrual cycle-related sialidase that could be involved in modifying the rheologic properties of mucus to favor sperm progression at fertilization. Its association with exosome-like vesicles also suggests a role in intercellular communication before and after fertilization.
Complex-protein-free botulinum neurotoxin type A in both dilutions effectively reduced severity of glabellar lines. There was no statistically significant difference in efficacy between the two dilutions.
