Alzheimer's disease is a devastating neurodegenerative disease characterized by accumulation of clumps (also called plaques) and bundles of fibers (also called tangles) in the brain, for which there is currently no cure. Sirolimus is an FDA-approved medication which may improve the blood flow to the brain. Part I: This study is designed to see if sirolimus treatment improves MRI blood flow to the brain in individuals with and without a genetic predisposition to Alzheimer's disease. Part I of this study is complete and no longer enrolling participants. Part II: Ongoing research will expand the genetic predisposition cohort and further explore the drug's impact on the lung perfusion via hyperpolarized xenon-129 gas MRI and the brain-vascular connection. Only subjects who are APOE4 carriers will be enrolled in Part II. Hyperpolarized xenon-129 gas MRI is a non-invasive technique in which a subject inhales a bolus of hyperpolarized xenon-129 gas which can be directly imaged by the MRI as it physiologically distributes itself throughout the lung interior and within tissue and red blood cells. It thus allows for direct imaging and quantification of regional lung function: ventilation, gas-exchange, and perfusion. The relationship between pulmonary vascular function and brain perfusion is largely unstudied. We hope to investigate the relationship between pulmonary vascular function and cerebral blood flow by quantifying both lung and brain perfusion before and after the administration of Sirolimus.

Earlier detection of disease recurrence will enable greater treatment options and has strong potential to improve patient outcomes. This project is translational and has the potential to lead to future translational research opportunities, including interventional trials in which therapeutic escalation is offered at the early circulating tumor DNA (ctDNA) molecular residual disease (MRD) detection timepoint. Ultimately, the integration of ctDNA into the clinical workflow has the potential to enhance cancer diagnosis, treatment, surveillance, and prognosis, and guide clinical decision-making in this era of personalized precision medicine.

Epstein Barr virus (EBV) is a virus which can cause infectious mononucleosis and is associated with certain kinds of cancer and multiple sclerosis. Researchers are looking for new ways to prevent disease related to EBV and have developed a new study vaccine (V350A and V350B). The main goal of this study is to learn about the safety and tolerability of V350A and V350B in healthy adults. Read Less

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

Within few years the peritoneal membrane of adult peritoneal dialysis (PD) patients undergoes substantial morphological transformation, including progressive fibrosis, vasculopathy and neoangiogenesis. Ultrafiltration capacity steadily declines and ultimately results in PD failure. In children, peritoneal biopsies demonstrating PD associated alterations have not yet been obtained. They, however, should be particularly informative, since secondary tissue and vascular pathology related to ageing or diabetes is absent. An international, prospective peritoneal membrane biopsy study in children on PD will therefore be performed. Biopsies will be obtained at time of PD catheter insertion, on occasion of intercurrent abdominal surgery (e.g. hernia repair, catheter exchange) and at time of renal transplantation. Quantitative histomorphometry and tissue protein expression analyses will be correlated with time integrated PD treatment modalities and functional characteristics as well as inflammatory and cardiovascular comorbidity surrogate parameter. Blood will be obtained during clinical routine sampling. Biopsies will be obtained during clinically indicated operations, without substantially increasing operation time and associated surgical risks. The detailed histomorphometry of the PD membrane will give additional information, potentially impacting on the individual PD regime. 3/2018: The analyses of the pediatric PD biopsy demonstrated early and major transformation of the peritoneal membrane with neutral pH low GDP fluids, and significant vasculopathy already in children with CKD stage 5, further progressing with PD. The underlying mechanisms are partly understood, only. In view of these major findings and the numerous open questions, collection of biosamples will be continued in children and also in adult PD patients. The following questions will be addressed: Molecular counterparts of peritoneal semi-permeability, solute and water transport (beyond AQP1), pathomechanisms and molecular and functional impact of peritoneal transformation with low and high GDP fluids, and the respective pathomechanisms and molecular and functional impact of vascular disease in CKD and with different PD fluids. The impact of renal transplantation following PD will be assessed in a subgroup of patients with tenckhoff catheter removal several weeks after transplantation and a functioning graft. Read Less

This is a 3-part study that includes a Part A, Part B, and Part C. Part A will study the safety and tolerability of the study drug known as LY3537031 in participants who are overweight and obese. Part B and Part C will study the safety and tolerability of LY3537031 in healthy participants. Part C will contain only Japanese and Chinese healthy participants. Blood tests will be performed to check how much LY3537031 gets into the bloodstream and how long it takes the body to eliminate it. Body weight will be measured. The study will last approximately 20 weeks excluding a screening period. Read Less

The main purpose of this study is to see how much of orforglipron (study drug) gets into the bloodstream and how long it takes the body to get rid of it when given as capsules compared to tablets in healthy overweight and obese participants. The safety and tolerability (side effects) of orforglipron when given as capsules and tablets will also be evaluated. The study will be conducted in two parts, with part A and B lasting up to approximately 25 and 22 weeks each respectively, including the screening period. Read Less

The goal of this study is to evaluate the role of transcription factor EB (TFEB) in adipose (fat) tissue macrophages (ATM) in regulating adipose tissue and systemic metabolic function in obesity. The investigators will assess the differences in ATM lipid metabolism in people with metabolically abnormal obesity and lean individuals. Both groups will have: * screening visit * imaging (body composition testing - dual-energy x-ray absorptiometry (DEXA) scans, magnetic resonance imaging \[MRI\] and magnetic resonance spectroscopy \[MRS\] scans) * Overnight visit with intravenous infusion (IV), muscle, and fat tissue biopsies Read Less

The goals of this research study are to: 1) understand why some people with obesity are protected from developing conditions such as type 2 diabetes and cardiovascular disease while others are more likely to develop obesity-related conditions; 2) assess the effect of small extracellular vesicles (sEVs also called exosomes), obtained from human participants, on metabolic function in cultured cells and in mice.

Patients with sleep apnea are at increased risk of developing cardiovascular disease - with women at potentially greater risk than men. Contributing mechanisms are not well understood, but may be related to how women respond to low oxygen and, given over 70% of patients with sleep apnea are obese, the impact of obesity. This project seeks to increase our understanding of mechanisms that may contribute to sex differences in the cardiovascular response to low oxygen with the hope that this knowledge will improve the efficacy of current therapies and support the discovery of novel therapeutics.
