Hemodynamics Monitoring During Lower Body Negative Pressure (LBNP) Induced Controlled Hypovolemia
To monitor the changes in central and peripheral monitors/waveforms during gradual hypovolemia induced by lower body negative pressure in healthy volunteers.
A Multi-center Study on Human Microecology Assisted Diagnosis of Colorectal Cancer
As for this research，we want to find whether the intestinal microecology (flora, peptidoglycan fragments) have certain distribution characteristics in colorectal diseases; whether it can predict the development of disease/as a prognostic indicator.
The Gut and Skin Microbiome in Vitiligo Disease Progression
Investigators plan to perform a pilot study that aims to characterize the microbiome of human vitiligo patients with both active and stable disease and compare this to the microbiome of age and sex matched controls. The investigators aim to answer the question whether the gut and skin microbiome of patients …
Metabolic Inflexibility is Related to Elevated Muscle Anaerobic Glycolysis
The focus of this proposal is on overweight (25>BMI<30 kg/m2) subjects, as these individuals exhibit a high risk of becoming obese and/or developing metabolic diseases. We hypothesize that in some overweight individuals there is a "metabolic program" in skeletal muscle which predisposes them to the development of obesity. Findings may …
Use of Blood Biomarkers for the Early Diagnosis of Hepatocellular Carcinoma (HCC)
The objective of this observational study is to evaluate the clinical utility of the combined assay of 3 biomarkers: α-FP, α-FP-L3 and DCP (simultaneously measured by µTASWakoTM i30 automated in vitro diagnostic system) in high-risk subjects to develop this neoplasm. In particular, it aims to: Evaluate the clinical utility of …
MRI Study of Blood-brain Barrier Function in CADASIL
Diffusion prepared pseudo-continuous ASL (DP-pCASL) is a newly proposed MRI method to noninvasively measure the function of blood-brain barrier (BBB). The investigators aim to investigate whether the water exchange rate across the BBB, estimated with DP-pCASL, is changed in patients with CADASIL, and to analyze the association between BBB water …
Performances on Cognitive Functions and Brain Function and Follow-up After Different Treatments in Patients With Autonomous Cortisol Secretion: a Single-center, Prospective, Observational Study
This is a single center, prospective, observational study to explore and evaluate the differences on cognitive function and brain function by functional-MRI in autonomous cortisol secretion patients, and the different treatments methods on the cognitive function and brain function in patients with autonomous cortisol secretion
Differences in Characteristics of Headache Patients With a Positive or Negative FRT: a Cross-sectional Comparison.
An observational study will be conducted to evaluate the differences in headache characteristics between a subgroup of cervicogenic headache patients with a positive and negative flexion-rotation test at the C1-C2 level. Differences may guide future treatment allocation and the use of more individualized treatment options.
A Longitudinal Study of Familial Hypereosinophilia (FE): Natural History and Markers of Disease Progression
Eosinophils are a type of white blood cell. Elevated eosinophil levels can damage the heart, nerves, and other organs, in the syndrome known as hypereosinophilic syndrome (HES). Some individuals have a hereditary form of HES known as familial eosinophilia (FE). More research on the causation and mechanisms of HES is …
Multi Center Observation of Sentinel Skin Graft for Detecting Acute Rejection After Renal Transplantation
The purpose of this study was to explore the accuracy of sentinel skin grafts from the same donor source in diagnosing renal allograft rejection, and to provide new ideas and options for the later clinical diagnosis of renal allograft rejection. Further, try to provide timing guidance for early immunization intervention.
