Clinical trials

The goal of this clinical trial is to compare how much glucoraphanin and sulforaphane from 3 different versions of broccoli extract supplements is absorbed into the body and excreted in urine. This study involves generally healthy adults age 18-60 years. The supplements contain glucoraphanin and myrosinase enzyme, both naturally occurring in cruciferous vegetables. Once ingested, glucoraphanin is converted to the bioactive compound sulforaphane, which is thought to have numerous health benefits, including cancer prevention. Participants will: * consume 3 different versions of broccoli extract supplements (glucoraphanin will range from 35-70 mg) * complete 3 separate 24 hour study cycles * submit blood and urine samples for 24 hours * follow diet restrictions (no cruciferous vegetables or condiments or phytochemical/herbal supplements for 1 week prior to and during each study cycle)

The goal of this study is to plan for a large scale evaluation of a program called Mindful After Cancer, or MAC. The MAC Program provides training in mindfulness, educational material about sexual health after cancer, and support to cancer survivors experiencing sexual and body image concerns. The main study aims are to: 1. Develop effective plans for recruiting participants across multiple sites 2. Evaluate participation in the program and surveys 3. Develop plans to train and supervise the professionals who will deliver the program. Researchers will compare study recruitment across three sites, aiming to identify the most efficient approach for a larger future trial. Participants who are randomly assigned to receive the MAC program will receive access to the 8-week program delivered by a trained mindfulness coach using videoconference and online materials. They will asked to participate in an interview about their experiences at the end of the program. Participants who are not randomly assigned to the MAC program will receive access to the program's educational materials after completing the final survey. All study participants will be asked to complete 3 online surveys. Participants randomly assigned to the MAC Program will also be asked to complete a one-on-one interview about their experience in the program.

The purpose of this study is to examine the impact of daily consumption of walnuts for 12 weeks on cognitive function, markers of inflammation and oxidative stress, and the gut microbiome in healthy adults age 55 years and older.

The aim of this study is to pilot test a comprehensive, personalized, media-augmented telehealth intervention ("SWISH") designed to improve sleep health among shift workers.
