This is a pilot research study to investigate the effects of a probiotic supplement (L. acidophilus, strain TW01) on substances found in the stool and bloodstream, gut bacteria composition, body composition, as well as any relationship of these substances with markers of inflammation. Lactobacillus acidophilus is commonly found in a variety of fermented foods, including yogurt, cheese, and kefir, due to its ability to produce lactic acid and other substances. This bacterium is generally well-tolerated in healthy individuals and has a longstanding history of safe use. The investigators are doing this pilot study to see if a particular probiotic, called L. acidophilus (strain TW01) and isolated from fermented coffee grounds, can make a positive difference in human gut and overall health. Specifically, the investigators want to look at how this probiotic affects certain substances in human stool and blood, the makeup of the bacteria in the gut, and aspects of body composition. The investigators are also interested in whether these changes relate to markers of inflammation, which can tell us more about their impact on overall health. This probiotic strain has been shown in other studies to be safe and well tolerated, and the investigators hope our research will help us better understand how it works and whether it might support health in humans.

The purpose of this study is to investigate the effects of consuming grape powder on immune profiles in healthy middle- and older-aged individuals. Specifically, the investigators are interested in evaluating the potential effects of grapes in influencing markers of immune function, inflammation, and metabolism that are known to change with aging. Grapes contain several nutrients and antioxidant polyphenols such as resveratrol, quercetin, vitamin K and fiber, which are known to promote heart and immune health. However, the effects of grapes on altering immune profiles within the context of aging is not well understood. Therefore, this study will explore how daily grape consumption impacts certain markers of immunity in healthy middle- and older-aged adults. The main study procedures include consumption of a freeze-dried grape powder and control powder (which tastes the same but has none of the grape compounds that are being studied) mixed with water as a beverage on a daily basis for 4 weeks each. The investigators will additionally ask that participants avoid eating grapes and certain other antioxidant/grape-related foods and beverages throughout the 13-week study. Participants will additionally be asked to complete surveys about their diet, physical activity, and medical history, as well as provide blood samples and body weight measures throughout the course of the study. Participation in the study is expected to last about 6.25 hours over the course of 13 weeks and will include 7 visits. Read Less

This study aims to examine the effect of cannabidiol (CBD) pre-treatment on brain microglial activation in healthy human subjects. Secondarily, this study aims to examine the effect of cannabidiol (CBD) pre-treatment on central pain-sensitization in healthy human subjects. Read Less

The purpose of this study is to evaluate the safety and tolerability, pharmacokinetics and pharmacodynamics, pH and food effect, and preliminary efficacy of BMS-986470 in healthy volunteers and participants with sickle cell disease. Read Less

The purpose of this study is to learn about the safety of the study medicine called PF-08049820 in healthy adults. The study will also see: * how the body processes the study medicine and * if food affects the amount of study medicine in the blood. The study medicine is developed for the treatment of moderate to severe atopic dermatitis, also known as eczema. People with this condition may have severe itching and rashes on the skin. The study is seeking participants who: 1. Are males or females who can no longer have children. 2. Are 18 to 65 years old. 3. Have a body mass index (BMI) of 16 to 32 kilograms per meter squared and a total body weight of more than 50 kilograms (110 pounds). For group 3 only: 4. Have 4 biological Japanese grandparents who were born in Japan. The study has two parts: Part A and Part B. Part A consists of 3 groups. In groups 1 and 2, there may be up to four dosing periods. During each dosing period, participants will take a single dose of the study medicine or placebo as liquid by mouth with or without food at the study clinic. A placebo does not have any medicine in it but looks just like the medicine being studied. The participants will stay at the study clinic for about 8 days and then can go home. During this time, the study team will observe the participants and take some urine and blood samples to test the level of the study medicine. The participants will return to the study clinic up to three more times to complete up to four dosing periods separated by at least 2 weeks. The participants will take increasing amounts of study medicine during each dosing period. After completion of the final dosing period, the participants will receive a follow-up telephone call about a month later. Group 3 may or may not be needed and will be decided by the study team if needed to collect results from participants who have 4 biological Japanese grandparents who were born in Japan. If group 3 is needed, then there will only be one dosing period as described above. Part B has 4 groups (Groups 4 to 7), each consisting of one dosing period. In all groups, participants will take multiple doses of the study medicine or placebo as tablets by mouth at the study clinic. Participants will be checked as described above and will receive a follow-up telephone call about one month after the last dose of study medicine or placebo. Group 7 may or may not be needed, depending on the results from previous groups, and will be decided by the study team. Read Less

The main purpose of this study is to determine whether hippocampal synaptic vesicle density estimated by hippocampal \[11C\]APP-311/\[11C\]UCB-J binding in individuals diagnosed with cannabis use disorder (CUDs) improves with at least 4 weeks of confirmed abstinence from cannabis, in comparison to healthy controls (HCs). Furthermore, any change in synaptic vesicle density will be placed in functional context by measuring verbal memory, which is sensitive to hippocampal function, before and after at least 4 weeks of confirmed abstinence. Finally, the relationship between hippocampal \[11C\]UCB-J binding in CUDs with measures of cannabis exposure (e.g., age of initiation, cumulative lifetime dose) will be explored. Read Less

The goal of this research study is to examine the endocannabinoid (eCB) function in vivo in individuals with opioid use disorder (OUD) by measuring cannabinoid receptor 1 (CB1R) availability. Read Less

The purpose of this clinical trial is to learn if the study medicine (called PF-07314470) is safe and how it gets in and out of the body in healthy people. Read Less

The aim of this study is to evaluate a new SV2A tracer, \[11C\]APP311, in healthy aging and neuropsychiatric disorders including psychotic disorders and cannabis use disorders. Read Less

In this study, the investigators hypothesize that THC alters the immunogenome in a cell type-specific fashion and alters cytokine production via epigenetic regulatory mechanisms and that these alterations differ between HIV-infected and HIV-uninfected host genomes. Read Less

The goal of this observational study is to characterize the brain processes of pain avoidance learning dysfunctions in individuals with opioid use disorder (OUD). The main questions it aims to answer are: Compared with healthy controls, do those with OUD exhibit impaired avoidance learning in response to pain? What are the brain processes that are associated with this avoidance learning dysfunction? Do these brain processes serve to predict future use or relapse? Researchers will compare those with OUD and healthy controls to determine avoidance learning dysfunction and its relationship with opioid use. Participants will be performing a learning task inside an fMRI scanner. Those with OUD will also be followed up for a year to determine future opioid use. Read Less
