Healthy Clinical Trials in Ann Arbor, MI

The purpose of this study is to assess whether Aquamin®, a multi-mineral natural product from red marine algae, can help reduce halitosis when taken for 90 days. Read Less

This study will explore potential links between atopic dermatitis and food allergy. This information will be useful to determine atopic dermatitis and food allergy share unique biochemical or genetic identifiers useful for diagnosing and treatments in the future. This is a mechanistic study consisting of obtaining blood and skin samples from participants at baseline. Individuals may also undergo a clinically indicated oral food challenge and have blood and skin samples collected at various times during the oral food challenge. This study will create a molecular map of the pathology of atopic dermatitis and food allergy. This information will be deployed to evaluate the hypothesis that atopic dermatitis and food allergy share unique genetic transcriptional signals in which the study team can then further analyze pathological pathways and cell types.

This trial is being completed to learn about how Aquamin® affects gastrointestinal permeability, or the control of material passing from inside the gastrointestinal tract through the gut wall into the rest of the body, in people with ulcerative colitis (UC), Irritable Bowel Syndrome with diarrhea (IBS-D), and in healthy individuals.

This project is being conducted to evaluate the impact of explosive synchronization (ES) and its treatment with non-invasive brain stimulation in fibromyalgia (FM). The study design has three components, however, only 2 aims are enrolling participants. The first part (Aim1) is a cross sectional assessment of brain network explosive synchronization activity, connectivity, and response to pain in healthy controls and age and sex-matched fibromyalgia patients; the third part (Aim 3) is a longitudinal assessment of fibromyalgia patients undergoing one week of sham followed by high-definition transcranial direct current stimulation (HD-tDCS) of the motor cortex (M1) or one week of ES HD-tDCS of a brain region identified from computer modelling (Aim 2).

The iCaRe2 is a multi-institutional resource created and maintained by the Fred & Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies. Read Less

The purpose of this study is to better understand mental illness and will test the hypotheses that while viewing affective stimuli, patient groups will show increased blood oxygenation level dependent (BOLD) signal by fMRI after lorazepam. This study will enroll participants between the ages of 16 and 60, who have a psychotic illness (such as psychosis which includes conditions like schizophrenia, schizoaffective disorder, and mood disorders). The study will also enroll eligible participants without any psychiatric illness, to compare their brains. The study will require participants to have 3-4 sessions over a few weeks. The initial assessments (may be over two visits) will include a diagnostic interview and several questionnaires (qols) to assess eligibility. Subsequently, there will will be two separate functional magnetic resonance imaging (fMRI) sessions in which lorazepam or placebo will be given prior to the MRI. During the fMRI the participants will also be asked to answer questions. Additionally, the participants will have their blood drawn, women of child bearing potential will have a urine pregnancy test, vital signs taken, and asked to complete more qols. Read Less

Repetitive transcranial magnetic stimulation (rTMS) is a powerful tool to non-invasively modulate brain circuits, brain plasticity, and behavior. This proposal will test the hypothesis that controlling behavioral state during focal multi-day rTMS of a brain region involved in grasping movements will enhance the functional specificity of the neuromodulation action among distributed brain regions involved in voluntary motor control and concomitantly improve manual dexterity. Results from this study will be used to optimize rTMS therapy for individuals with neuromotor impairments by controlling behavioral state to improve the efficacy of rTMS treatment. Healthy volunteers that qualify for this study will have motor skill assessments and basic neuromotor testing (using neurophysiology with TMS and functional Magnetic Resonance Imaging (fMRI) scans). Participants will be asked to come in for up to nine sessions that include 1 screening session, 5 consecutive daily rTMS sessions and 3 assessment sessions with resting-state and task-based fMRI, neurophysiology with TMS, and hand motor tasks over the course of 3-4 weeks.

The purpose of this research study is to understand the biological mechanisms of stress vulnerability (being susceptible to stress) and stress resilience (being able to recover readily from stress), obtain biomarkers (a biological indicator) for stress resilience and to devise strategies for prevention and treatment of stress-related disorders.
