Chronotherapy of 5-Aminosalicylic Acid in Ulcerative Colitis

The hypothesis of this study is that appropriate time of day of administration of oral, once daily 5-ASA therapy in alignment with the host circadian rhythms will improve subclinical inflammation and microbial structure/function and increase mucosal 5-ASA levels. All subjects will be randomized to once daily 5-ASA medications at two …

Near-infrared Spectroscopy and Electroencephalography to Assess Cortical Activation During Motor Tasks in Infants and Toddlers With and Without Cerebral Palsy

Background New ways to study the brain as people move include near-infrared spectroscopy (NIRS) and electroencephalography (EEG). NIRS uses laser light shone through the scalp to look at blood flow in the brain which increases with movement. EEG records electrical activity in the brain. Little is known about brain activity …

Effect of HSD3B1 (1245C) Gene Mutation on Treatment of Stage I-III Breast Cancer

This stage IV trial examines how a mutation in HSD3B1 (1245C) gene affects treatment of stage I-III breast cancer. This trial may help researchers determine if mutations in HSD3B1 decreases the efficacy of aromatase inhibitor therapy such as letrozole. Letrozole may stop the growth of cancer cells by blocking some …
