Light Scattering Spectroscopy to Determine Brain Tumors

This study will use light scattering spectroscopy (LSS) to analyze brain tissue removed from patients during brain surgery to determine if this new technology can be used to differentiate between normal and cancerous cells. LSS focuses light on cells or tissues, and the way that light is reflected back from the tissues provides information about the size of cells and the density of the cell nuclei (the part of the cell that contains the genes). Patients between 18 and 7...

Transcranial Pulse Near-Infrared Light in Generalized Anxiety Disorder: a Placebo-Controlled Study

Transcranial Light Therapy involves non-invasive and invisible beams of light that increase energy metabolism in the brain. Transcranial light therapy has been found to promote brain metabolism which may help people with anxiety. The research team proposes a novel approach to treating anxiety by using transcranial light therapy.

Age of Exposure and Immunity to Malaria in Infants

The overall objective is to evaluate the effect of exposure to Plasmodium (P.) falciparum erythrocytic stage antigens during different periods of infancy on the development of naturally acquired immunity (NAI). Hypothesis: Exposure to P. falciparum prior to 5 months of age does not result in the development of NAI, while exposure to P. falciparum after 5 months of age leads to the development of NAI. The risks of clinical malaria and anaemia during the second year of life ...

Clinical Trial of Light Therapy for Epilepsy

This study is designed to investigate whether light therapy may be an effective treatment for some people with epilepsy. Light treatment is already an established treatment for depression. The chemical systems in the brain that are disrupted when someone becomes depressed, overlap with some of those that can be affected during some epileptic seizures. The investigators have designed this study to see whether light therapy may also lead to a decrease in seizures in people who ha...

PET Imaging Study of Recovered Anorexics

Several studies in the past suggest that individuals who have or had anorexia nervosa may have alterations in brain serotonin. Serotonin seems to play an important role in regulating anxiety, mood, and other symptoms found in anorexia nervosa. We will be using a technology called Positron Emission Tomography (PET), which is a method used to take pictures of the body, in this case, the brain. Study participants will undergo two baseline PET scans on the first day of the study. T...

Light Therapy in Disorders of Consciousness: Behavioral, Neuroimaging and (Neuro)Physiological Assessments.

In this randomized, double-blind, placebo controlled project, the investigators would like to assess the effect of a specific light, as compared to placebo light, on wakefulness (circadian rhythms, homeostasy, sleep-wake cycle), awareness (perceptual and self consciousness), cognition (attention, memory) and underlying brain activity (electrophysiology and neuroimaging)

The "Light for the Brain" Study

Cognitive impairment (such as memory problems) due to cancer and its treatment can interfere with quality of life and can linger long after treatment has ended, yet research examining cognitive rehabilitation approaches has produced limited clinical benefit. The proposed study will provide information about systematic light exposure for the treatment of cognitive impairment in hematopoietic stem cell transplant (HSCT) survivors and will investigate how it works. This study woul...

Effects of Dietary Interventions on Serum and Macrophage Atherogenicity

While previous atherosclerosis-related studies have focused mainly on the atherogenicity of lipids, the proposed study aims to investigate the effects of other dietary factors, i.e. monosaccharides, disaccharides, amino acids, or artificial sweeteners, on the atherogenicity of serum or macrophages. Findings from the current proposed study may shed light on yet unknown mechanisms by which the above dietary factors could affect atherosclerosis development and CVD risk and hence c...

Magnetic Resonance Imaging of Brain Development in Attention Deficit Hyperactivity Disorder

The primary purpose of this study is to investigate brain whether ADHD represents a disruption or a delay of brain development. Children and adolescents both with and without ADHD are asked to participate in several MRI sessions, two years apart. This will allow us to chart brain development over time, both in typical development and ADHD, and therefore to address whether ADHD represents a disruption or a delay of typical brain development.

Influence of Light Exposure on Cerebral MAO-A in Seasonal Affective Disorder and Healthy Controls Measured by PET

This study aims to assess differences in monoamine oxidase A (MAO-A) distribution in the brain between seasonal affective disorder patients and healthy controls using positron emission tomography. In addition the investigators aim to demonstrate the impact of light therapy on MAO-A distribution.

Effects of Red Light LED Therapy on Body Contouring

The purpose of this study is to determine whether red light therapy using LED 650nm red light for body contouring of the waist, hips and thighs is as effective as red light therapy using Laser 635nm red light.

Magnetic Resonance Imaging of Brain Development in Autism

The purpose of this study is to investigate brain development in autism by longitudinally assessing children with autism, as well as typically developing controls, using advanced MR techniques. We will use longitudinal diffusion tensor imaging (DTI) measures to investigate the protracted development of long-range white matter fibers in autism. In addition, we will investigate the effect of autism risk genes on brain development.

Correlation of Volumetric Brain Analysis With Development at 18 Months

The study will correlate the volumes of the brain obtained from magnetic resonance imaging (MRI) scans done at term gestation for infants born prematurely who weighed less than 1000 grams at birth with their corresponding development at 18 months corrected age.

A Study of the Genetic Analysis of Brain Disorders

A study of the complex genetics of brain development will be undertaken with an emphasis on those genes that cause the most common structural brain anomaly in humans called holoprosencephaly (HPE). This malformation of the brain can result from either environmental or genetic causes, and it is the aim of these investigations to determine the genes responsible for both normal and abnormal brain development through the study of patients with this disorder. Mutations in one such...

Daily Light Exposure for Sleep Disturbance, Fatigue, and Functional Outcomes in Acute Brain Injury

The purpose of this study is to assess the safety and efficacy of daily morning exposure to colored light in patients receiving acute inpatient rehabilitation services for stroke, traumatic brain injury, or non-traumatic brain injury with sleep disturbances such as poor nighttime sleep and/or excessive daytime sleepiness.In a two-arm randomized placebo-controlled study with pre-exposure and post-exposure assessments, we are comparing the effects of daily morning exposure to eit...

A Retrospective Analysis of the Effects of Red Light Therapy on Body Contouring

The purpose of this study is to determine whether red light therapy using LED 635nm red light for body contouring of the waist, hips and thighs is as effective as red light therapy using Laser 635nm red light.

Influence of Oxytocin on Romantic Jealousy

The aim is to evoke romantic jealousy between couples and investigate whether oxytocin has effect on it.

High Light and Low Light Dose PDT in Glioma

RATIONALE: Photodynamic therapy uses a drug, such as porfimer sodium, that becomes active when it is exposed to a certain kind of light. When the drug is active, tumor cells are killed. Giving photodynamic therapy after surgery may kill any remaining tumor cells. PURPOSE: This randomized clinical trial is studying two different light doses of photodynamic therapy using porfimer sodium to compare how well they work in treating patients who are undergoing surgery for recurrent m...

Brain Development Research Program

Dr. Elliott Sherr and his collaborators at University of California, San Francisco (UCSF) are studying the genetic causes of disorders of cognition and epilepsy, in particular disorders of brain development that affect the corpus callosum, such as Aicardi syndrome, as well as two additional brain malformations, polymicrogyria and Dandy-Walker malformation. The goal of the investigators' research is to use a better understanding of the underlying genetic causes as a foundation t...

Effects of Different Colors of Light on Human Physiology

This study will determine which color of light is most effective in stimulating a range of biological functions in humans including activation of sleep-wake regulatory system (alertness, performance, microsleeps, brain activity), activation of the nervous system (heart rate, temperature, blood pressure, breathing rate), and shifting the timing of the internal 24-hour (circadian) pacemaker.

Seasonal Affective Disorder and Visual Impairment

As a subtype of major depressive disorder, seasonal affective disorder (SAD) or winter depression causes severe reductions in both quality of life and productivity and results in high morbidity and frequent sick leave (1). SAD is a prevalent disorder with rates as high as 3-5% in central European countries and 8-10% in Scandinavian countries. In our recent screening survey among persons with severe visual impairment or blindness (visual acuity < 6/60), we found a strikingly hig...

Research Study of Treatment for Winter Depression With Different Colors of Light

The specific aim of this study is to test the hypothesis that light stimuli concentrated around 468 nm will evoke a significantly stronger therapeutic response in SAD patients compared to light stimuli concentrated around 654 nm at an equal photon density. The secondary objective of this study is to determine the efficacy of different colors and levels of light in order to optimize therapeutic benefit, while also minimizing side effects and maintaining safety of light exposure...

The "PC-LIGHT" Study

Fatigue due to cancer and its treatment (for example, radiation therapy) can interfere with quality of life and can linger long after treatment has ended, yet research examining preventative approaches has produced limited clinical benefit. The proposed study will provide information about systematic light exposure for the prevention of fatigue in prostate cancer patients undergoing radiation therapy and will investigate how it works. This study would facilitate the development...

Comparison of Abnormal Cortical Development in Brain Malformations on Postmortem Imaging With Autopsy

Examination of the fetal brain at autopsy is technically challenging because of marked fragility of the brain tissue. Studies have found postmortem fetal MR to be particularly useful in examining gross structural abnormalities in fetal brain and spine. We have recently included postmortem MR as part of the radiological studies for fetal autopsy workup. Using the same MR data, the development of normal layering of the brain, also called laminar organization, can also be assessed...

Light Exposure to Treat Sleep Disruption in Older People

The purpose of this study is to test whether shifts in the timing of the biological clock to a later hour (phase delay shifts of the human circadian system) can be produced in response to four successive evenings of light exposure, and whether that phase shift will result in greater evening alertness and greater nighttime sleep efficiency. Three different light sources will be compared: 1) standard fluorescent light; 2) blue-enriched light; 3) incandescent fluorescent light.
