The Myelin Disorders Biorepository Project (MDBP) seeks to collect and analyze clinical data and biological samples from leukodystrophy patients worldwide to support ongoing and future research projects. The MDBP is one of the world's largest leukodystrophy biorepositories, having enrolled nearly 2,000 affected individuals since it was launched over a decade ago. Researchers working in the biorepository hope to use these materials to uncover new genetic etiologies for various leukodystrophies, develop biomarkers for use in future clinical trials, and better understand the natural history of these disorders. The knowledge gained from these efforts may help improve the diagnostic tools and treatment options available to patients in the future.

open study

This phase III trial compares the effect of adding lomustine to standard chemotherapy with temozolomide and radiation therapy versus temozolomide and radiation therapy alone in shrinking or stabilizing newly diagnosed MGMT methylated glioblastoma. MGMT methylated tumors are more likely to respond to temozolomide chemotherapy. Temozolomide is in a class of medications called alkylating agents. It works by damaging the cell's DNA and may kill tumor cells and slow down or stop tumor growth. Lomustine is a chemotherapy drug and in a class of medications called alkylating agents. It damages the cell's DNA and may kill tumor cells. Radiation therapy uses high energy x-ray photons to kill tumor cells and shrink tumors. Adding lomustine to standard chemotherapy with temozolomide and radiation therapy may shrink or stabilize glioblastoma.

The purpose To determine the diagnostic potential of various biological markers in blood and cyst fluid aspirates from patients with Pancreatic Cystic Lesions (PCLs). Research design This is a 10-year prospective cohort and pancreatic cyst fluid repository study enrolling all patients diagnosed with pancreatic cyst and undergoing the cyst aspiration. Procedures to be used Blood Sample Cyst Fluid Sample Data Collection: Medical Record Number Demographics (age, sex, gender, race) Contact information History of alcohol use and IV and other recreational drugs and narcotics use/abuse Medication history Past hospitalizations, diagnoses, and treatment Physical examination findings Imaging data of abdominal and chest regions, including and not limited to ultrasonography, magnetic resonance imaging (MRI), computed tomography (CT) Future admissions, diagnoses, treatment including histopathological findings of resected specimens and blood reports End of study data: clinical progression of disease, cyst size, wall thickening, calcification, communication with pancreatic duct, string sign, cytology, immunohistochemical findings, assay levels of lipase, amylase CEA (carcinoembryonic antigen), carbohydrate antigen19-9 (CA 19-9), and other biomarkers.

The purpose of the study is to test the hypothesis that functionally navigated repetitive TMS stimulations to the prefrontal cortex (PFC) modulate aberrant cortical electrical activities at PFC circuitry. The TMS location of the PFC site will be individually localized by the symptom-related functional connectivity between PFC and symptom related areas (such as the auditory and language processing cortex). The investigators predict that such modulation will correct abnormal activities in patients with schizophrenia, reduce symptoms, especially auditory hallucination, and improve working memory/sustained attention performance.
