Unfortunately, the biological ramifications of AN\u2010induced oxidative stress on the brain are largely unknown. Our lab uses the preclinical activity\u2013based anorexia (ABA) paradigm to model symptoms of AN. The goal of the present study was to determine how ABA experience affects oxidative state and its consequences in adolescent female rats.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>We compared systemic glutathione and cysteine plasma concentrations and medial prefrontal cortex (mPFC) mitochondrial fission in ABA animals at maximum weight loss or following 10\u2010days of weight recovery to levels in age\u2010matched sedentary (SED) control rats.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>ABA animals at maximum weight loss had significantly lower plasma levels of cysteine and glutathione compared to SED controls.
