Study of Placental Function in Healthy and Pathological Pregnancies
The purpose of this study is to establish a tissue and data repository consisting of samples of human placentas, umbilical cord blood, and maternal blood, collected at the time of delivery. Specimens will be used in cellular, molecular, and functional studies to learn more about changes in placental structure and …
ctDNA Methylation Application in Postoperative Relapse and Adjuvant Chemotherapy Efficacy Evaluation
In this study, the investigators aimed to apply their previously developed multi-locus blood-based assay targeting circulating tumor DNA methylation to monitor postoperative relapse and evaluate adjuvant chemotherapy efficacy in resected stage I and stage II (without high risk) colorectal cancer after radical resection.
Factors Affecting the Quality of Life After Ischemic Stroke in Young Adults
Despite a generally favourable 3-month functional outcome and a very low mortality, young ischemic stroke (IS) patients face to reduced quality of life associated with a complexity of problems or "invisible dysfunctions" after IS. Better identification and understanding to these factors may improve stroke rehabilitation and stroke self-management programmes, wich …
Proteomics Study of Mild Cognitive Impairment and Alzheimer's Disease
This study intends to adopt standardized and rigorous cross-sectional research, collect biological specimens (including blood, feces, urine, saliva and tongue coating) from eligible subjects, and use liquid chromatography/mass spectrometry (LC-MS/MS) technology to explore early warning indicators of protein in patients with mild cognitive impairment and Alzheimer's disease
Japanese CTO PCI Expert Registry
The purpose of this study is to establish a consensus of treatment strategy of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) through patient registry of PCI for CTO performed by Japanese certified operators.
The Impact of Anti-thrombosis on Cerebral Microbleeds and Intracranial Hemorrhage in Ischemic Stroke Patients
The purpose of this prospective cohort study is to investigate whether antithrombotic therapy in the secondary prevention of ischemic stroke increases the risk of the emerging CMBs and whether the change is associated with an increased risk of intracranial hemorrhage, providing an imaging evidence for individualized antithrombotic therapy in such …
