Unveiling the Neural Mechanisms of 5-HT7 in Sleep Apnea Induced by Arousal Dysregulation
Obstructive sleep apnea (OSA), recognized as a highly prevalent sleep breathing disorder with severe complications, features a complex etiology. Poor understanding of disease pathogenesis limits the overall efficacy of interventions. Studies have found that upregulation of 5-HT7 expression in the lateral hypothalamus (LH) could reduce arousal threshold (ArTH) and induce …
Dynamic Hormone Profiling and Multimodal Data Capture in Primary Aldosteronism
This study is a observational study applying 24-hour microdialysis methodology to perform dynamic multisteroid adrenal hormone profiling of patients with suspected or confirmed PA. Simultaneous registration of blood pressure, tissue glucose, sleep pattern, activity level and food intake registration may be performed. The overall objective is to develop a novel, …
In Situ Exploration of Vascular Function in Vasoplegic Shock Following Cardiac Surgery With Cardiopulmonary Bypass
The goal of this observational study is to assess in situ vascular function, glycocalyx and microcirculation in postoperative vasoplegic shock following cardiac surgery with cardiopulmonary bypass. The main question is to investigate the relationship between NO-dependent vasomotor reserve and the presence of vasoplegic shock following cardiac surgery with cardiopulmonary bypass. …
Multimodal Imaging Assessment After Revascularization in Patients With Acute Myocardial Infarction
This prospective cohort study will enroll 20 patients clinically diagnosed with first-time acute myocardial infarction (AMI) who underwent interventional procedures (including percutaneous coronary intervention [PCI] and balloon angioplasty) at the Affiliated Hospital of Qingdao University. Patient data, including routine blood and urine tests, blood biochemistry, electrocardiograms (ECG), imaging studies, and …
A Point-of-care Electrochemical-based Device for Rapid Detection of Fibrinogen on Type A Aortic Dissection Surgery
This study compares the results of the existing fibrinogen concentration monitoring technology to the Electrochemical-based device, a point-of-care and rapid method,using a small amount of extra blood obtained in Type A Aortic Dissection Surgery.
NMR Based Metabolomic Study of Serum Biomarkers in Patients With Parkinson's Disease and Atypical Parkinsonian Syndrome
At present, the diagnosis of Parkinsons disease(PD) mainly relies on clinical symptoms and is easily confused with atypical Parkinsonian syndrome(APS) in the early stages. There is an urgent need for reliable biomarkers. This project aims to use metabolomics technology based on proton nuclear magnetic resonance spectroscopy to study the metabolomic …
Observation of the Response to Ovulation Triggering on the Day of Intrauterine Insemination and Correlation Between Progesterone Level and Pregnancy Rate (OVUL-IIU)
Intrauterine inseminations (IUI) are a commonly used technique in assisted reproductive technology (ART) to help women conceive, whether within a couple or as single individuals. However, national success rates remain modest, with an average live birth rate of 10% per cycle, which leads many ART centers to favor in vitro …
Clinical Application of PET Imaging Targeting MSLN in Malignant Tumors
The project aims to perform integrated PET/MR or PET/CT visualization of patients with clinically suspected or confirmed pancreatic cancer, ovarian cancer, lung adenocarcinoma and other malignant tumors with high MSLN expression and healthy volunteers, using targeted MSLN-specific imaging agents (taking [68Ga]Ga-NOTA-MSLN antibody fragment as an example), to achieve the following …
Efficacy of Neoadjuvant Subcutaneous Trastuzumab-Pertuzumab in Algerian Women With Locally Advanced HER2 Positive Breast Cancer
This study aims to find out how effective and well-tolerated the subcutaneous form of trastuzumab-pertuzumab (known as Phesgo) is when given before surgery (neoadjuvant treatment) to Algerian women with early stage, HER2-positive breast cancer. The study will take place in three oncology centers in Algeria (Blida, Aïn Defla, Médéa) and …
German Registry of Alzheimer's Disease Treated With Transcranial Pulse Stimulation
This study will primarily investigate the safety and secondarily the effect and applicability of Transcranial Pulse Wave Stimulation (TPS) for the treatment of Alzheimer's disease in the context of a PMCF study (Post-Market Clinical Follow-up). The multicenter, prospective data collection should help to optimize the stimulation protocol, as well as …
