Filter by:Background: - Skin disease can have many causes. It can have widespread consequences, and in rare cases can lead to death. Researchers want to determine the causes of various types of skin diseases and find a way to treat them. Objectives: - To determine the causes of various skin diseases and find ways to treat them. Eligibility: - People ages 2 and older who have: - A skin disease or at risk of developing a skin disease OR - A family member of persons with a skin disease - Healthy volunteers ages 2 and older Design: - Participants will be screened under a separate protocol. - Participants may take a survey about how their skin condition affects their quality of life. - Participants will have a medical history and a physical exam including a detailed skin exam. Pictures will be taken of their skin to document any skin disease. - Participants will have specimens collected. This may include: - Several teaspoons of blood taken at each visit - Stool samples - Nail and body fluid (like saliva) samples - Cheek swabs. The inside of the cheek will be scraped for about a minute in each direction to collect cells. - Collection of skin samples with: - A swab (like a Q-tip) - Gently scraping skin to remove the outer layers of cells - Applying and removing 1-inch pieces of tape - Participants may have up to 4 skin biopsies in 12 months, with 4 separate biopsies taken each time. - An area of skin will be numbed with an injection. - A piece of skin the size of a pencil eraser will be removed using a small instrument. - A flat scar usually develops at the biopsy site.
Sleep deprivation slows reaction time, reduces vigilance and impairs judgment and information processing. Chronic effects include metabolic dysfunction, cardiovascular disease and cancer. Sleep deprivation affects quality of life when it causes errors in judgment, whether these occur behind the wheel of an automobile or in a hospital. Armodafinil, a non-amphetamine wakefulness promoting medication, indicated for excessive sleepiness associated with obstructive sleep apnea, narcolepsy, and shift work sleep disorder is used to mitigate the effects of sleep deprivation. This study will characterize the effect of armodafinil on driving simulator performance. The effects of armodafinil compared to placebo will be studied in a double blind crossover trial involving 10 healthy subjects with serial assessments at baseline and after extensive sleep deprivation. Using simultaneous electroencephalogram (EEG) recording during simulated driving and neurocognitive assessments of vigilance, the relationship between brain activity and cognitive performance will be established.
The family of inflammatory/autoimmune systemic diseases (IAD) form a continuum from pure inflammatory diseases to pure autoimmune diseases, encompassing a large panel of inflammatory diseases with some autoimmune components, and vice versa. Cross phenotyping of patients with IAD should be heuristic and help revise the nosography and the understanding of these diseases.
The purpose of this study is to characterize the safety, tolerability and plasma pharmacokinetic (PK) profile of TAK-915 when administered as single and multiple oral suspension doses at escalating dose levels in healthy participants, including elderly participants.
Comparative PK study after single SC application of Afolia and the reference product (US Gonal-f®). Objective: To demonstrate equivalence within 80%-125% margin of the reference product for the area under the curve (AUC) of Afolia.
The aim of this study is to investigate the effects of Methylphenidate on neural activity underlying inhibitory control and error monitoring in healthy adults. More specifically, the investigators aim to establish the baseline modulatory effect of Mehtlylphenidate on bottom-up and top-down aspects of these cognitive processes. This work will further our understanding of Attention Deficit Hyperactivity Disorder, Methylphenidate, and executive functioning.
In this clinical study, the safety and tolerability of GNbAC1 as a treatment for MS patients will be evaluated in healthy male volunteers.
The purpose of this study was to determine rates of absorption of Ibuprofen and Paracetamol formulations.
The purpose of this study was to evaluate the safety, tolerability, and pharmacokinetics of MLN3126 when administered as a single dose of tablets at escalating dose levels in healthy participants.
Background: - Painful stimuli cause changes in a network of brain regions called the "Pain Matrix." But most of these regions respond to many other stimuli, not just pain. Researchers want to understand how different factors influence pain. They want to test what happens when people expect different levels of pain and receive treatments that can modify pain. They want to see if these factors influence decisions about pain and how the body responds to it. They also want to compare pain with responses like taste and vision. Objectives: - To better understand how pain and emotions are processed and influenced by psychological factors. Eligibility: - Healthy volunteers ages 18-50. Design: - This study requires 1 to 2 clinic visits that last 1 to 3 hours. - Participants will be screened with medical history and physical exam. - Some participants will have one or more magnetic resonance imaging (MRI) scans of their brain. For MRI, participants will lie on a table that slides in and out of a cylinder. The scanner makes loud knocking noises. They will get earplugs. - Participants heart activity will be recorded with electrocardiogram. Their pulse, sweating, and breathing will be monitored. - Some participants will take a taste test. Others may perform simple tasks. Others may receive pain in their arm, leg, or hand. The pain will come from heat or electric shocks. Others may judge pain using a topical pain-relieving cream. Some of these tests may be given during MRI. - Participants will fill out questionnaires. - The study will last 3 years.
