 “For the primary time, we will see that nicotine works to shuts down the estrogen manufacturing mechanism within the mind of girls. We had been shocked to see that this impact could possibly be seen even with a single dose of nicotine, equal to only one cigarette, displaying how highly effective the consequences of smoking are on a girl’s mind. This can be a newly-discovered impact, and it’s nonetheless preliminary work. We’re nonetheless unsure what the behavioural or cognitive outcomes are; solely that nicotine acts on this space of the mind, nonetheless we observe that the affected mind system is a goal for addictive medicine, similar to nicotine”.

The researchers, from Uppsala College in Sweden, labored with a gaggle of ten wholesome feminine volunteers. The ladies got a commercially accessible nicotine dose intranasally, and on the identical time had been injected with a radioactive tracer connected to a molecule which binds to the enzyme aromatase: aromatase, also called estrogen synthase, is the enzyme accountable for the manufacturing of estrogen. MRI and PET mind scans enabled the researchers to visualise each the amount of aromatase and the place it was situated within the mind. The researchers discovered {that a} single dose reasonably diminished the quantity of aromatase within the mind. Learn extra right here.
