This study looks at whether eating 1.5 ounces of pistachios every day for six months can lower inflammation and increase lean body mass in active adults aged 40 to 60. Participants will be randomly assigned to eat pistachios or avoid them while keeping their usual diet and exerci…

This study tests whether a gentle ultrasound beam aimed at the brain can reduce anxiety. 44 people with high or low anxiety will receive either real or fake ultrasound while their reactions to stressful tasks are measured. The goal is to see if this noninvasive technique can damp…

This study explores whether low-intensity focused ultrasound (LIFU) can temporarily change brain activity to reduce chronic pain. Eighty adults with moderate-to-severe pain lasting at least 3 months will receive brain scans, pain tests, and questionnaires over 10 weeks. The goal …

This study looks at whether two common artificial sweeteners, saccharin and acesulfame potassium, affect blood sugar control in older adults with prediabetes. Researchers will monitor 30 participants over 8 weeks using continuous glucose monitors and oral glucose tolerance tests.…

This study explores whether low-intensity focused ultrasound (LIFU) aimed at specific brain regions can influence how the body controls automatic functions like heart rate and blood pressure. Researchers will apply LIFU or a sham (fake) version to 80 volunteers and measure change…

This study aimed to understand how a person's socioeconomic status (like income and education) affects their recovery from substance use disorder. Researchers planned to follow adults in early recovery for up to 3 years, measuring changes in social functioning, quality of life, a…

This study explores whether gentle sound waves aimed at the head can temporarily change brain activity and improve memory. Researchers will use MRI and CT scans to map each participant's brain, then apply low-intensity focused ultrasound or a sham (fake) treatment. Participants w…

This study follows 117 young adults (ages 23–28) who were part of a previous study since adolescence. Researchers use brain scans and surveys to understand how changes in the brain relate to smoking, drinking, and drug use. No treatment or medication is involved—only observation …

This study looks at whether imagining positive future events (Episodic Future Thinking) and using low-intensity focused ultrasound on the brain can help people with both chronic pain and alcohol use disorder. Ten adults will try these interventions and report changes in pain, cra…

This long-term study follows 733 adults with alcohol use disorder to learn what helps people recover and what leads to relapse. Participants complete surveys and tasks about their drinking, emotions, and daily life over time. The goal is to find patterns that could guide future p…

This study is testing how different pressure levels of low-intensity focused ultrasound (LIFU) affect brain activity related to pain. Researchers will use EEG and fMRI to measure brain responses in 25 healthy adults before and after ultrasound. The goal is to understand how LIFU …

This study aimed to test a new brain imaging technique called transcranial functional ultrasound (tFUS) and compare it with standard functional MRI. Researchers planned to see if tFUS could detect brain activity changes during tasks or during low-intensity focused ultrasound stim…
