TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['The aim of this study was to assess the protective effects of vitamin A in a rat model of colitis to elucidate a possible mechanism of action.', 'Male rats were fed for 21\xa0d with either a normal diet or high vitamin A diet (5000 IU/d). On day 22, colitis was induced with 2,4,6-trinitrobenzenesulfonic acid (TNBS). Rats were sacrificed after 24\xa0h and colonic tissue was removed for evaluation.', 'Morphologically, in the supplemented group preservation of tissue architecture, no vasculitis or necroses were detected. Biochemically, decreased myeloperoxidase activity and protection of the mitochondria as evaluated by preserving tissue oxygen consumption, mitochondrial DNA, and expression of cytochrome c, was observed. Vitamin A supplementation also increased the levels of nuclear respiratory factor (NFR)-1 and mitochondrial transcription factor-A (TFAM) in normal colon tissue and in colon tissue under inflammatory conditions.'] Does vitamin A exert its antiinflammatory activities in colitis through preservation of mitochondrial activity?
OUTPUT:

agent
yes
