Role of Red Blood Cells in Cardiovascular Disease

The risk of myocardial infarction is dependent on cardiovascular risk factors including type 2 diabetes (T2D) but underlying mechanisms are poorly understood. We identified that red blood cells (RBCs) mediate beneficial cardiovascular regulatory effects under hypoxic/ischemic conditions via signaling by nitric oxide (NO) and soluble guanylate cyclase (sGC) in the …

Development of Gastrointestinal Symptoms in Patients With Anorexia Nervosa and Bulimia Nervosa During Weight Rehabilitation Over Time, Depending on the Nutritional Strategy

This prospective observational study investigates the development of gastrointestinal (GI) symptoms in patients with anorexia nervosa (AN) and bulimia nervosa (BN) during multi-week inpatient weight rehabilitation. The study explores how the predominant nutritional strategy-flexitarian, vegetarian, or vegan-relates to changes in GI symptoms over the course of treatment. In addition to …

Metabolic Profile of Bone in Professional Athletes

Physical activity is a key stimulus for bone metabolism through both direct mechanisms (e.g., as a result of the applied load and/or impact) and indirect mechanisms (e.g., the activation of several metabolic pathways and the production of several mediators and effectors that have systemic effects). However, different kinds of physical …

Proof-of-concept Study on Dyspnea Analysis Via GapCO2

Patients presenting to the emergency department with acute dyspnea undergo arterial blood gas measurement and monitoring of transcutaneous capnography using the TCM5 monitor. The aim of this study is to determine whether GapCO2, the difference between transcutaneous and arterial pCO2 (PaCO2 - PtcCO2), is correlated with the congestive or non-congestive …

Natural History Study to Determine Drug Metabolism Phenotype and Appropriate Germline Source DNA in Patients Undergoing Allogeneic Hematopoietic Stem Cell Transplant

Background After an allogeneic hematopoietic stem cell transplant (HSCT), the donor genome is found in the recipient s circulation and tissues. Post-HSCT recipients may receive a medication in which the dosing needs to be adjusted based on genetic variation. While genes in donor genome may influence dosing and administration of …

Development, Application, and Mechanistic Investigation of a Novel Minimally-Invasive Bidirectional Epidural Cerebellar Stimulation Technique for Cerebellar Cognitive Affective Syndrome

Building on previous findings regarding microglial immune function and the immunosuppressive effects of glucocorticoids, this project centers on the cerebellum's role in cognitive science. Using Cushing's syndrome-induced cerebellar atrophy leading to CCAS as a model, we aim to elucidate the pathogenic mechanisms governed by the neuro-adrenal-immune network and to uncover …
