Premenstrual steroids?
Article Abstract:
Premenstrual syndrome (PMS) is distinguished by anxiety, depression and mood swings, occurring during the two weeks before menses. The menstrual cycle is linked with fluctuations in certain steroids thought to be involved in PMS. Smith and colleagues have reported on a possible link between the neuroactive steroids and an animal model of PMS. The neuroactive steroid link could prove to be involved in ageing, stress, alcohol abuse and sedative-hypnotic actions.

Psychoactive smoke
Article Abstract:
Chronic decreases in monoamine oxidase B (MAO B) increase dopamine levels, inducing nicotine self-administration or cigarette addiction. Cigarette smokers exhibit a 40% decrease in MAO B levels and reduced risk of developing Parkinson's disease. The smoking-initiated block of MAO B decreases peroxidase synthesis and related oxidative damage. The decrease in MAO B combined with nicotine addiction may generate the epidemiological effects of smoking.
