Filter by:New biomarkers that predict the development of renal dysfunction in patients with aortic surgery are urgently needed. The investigators investigate whether urinary (TIMP-2)x(IGFBP7) predicts postoperative Acute Kidney Injury and/or need for Renal Replacement Therapy (RRT) in patients after aortic surgery (including EVAR).
The aim of the study is to test the feasibility of four-drug, interval-compressed regimen in osteosarcoma. Primary objective is to explore the toxicity and mortality related to treatment. Secondary objectives are to examine tumor necrosis rates after neoadjuvant chemotherapy, and to evaluate the usefulness of circulating cell-free DNA, survivin, or transforming growth factor-beta1 levels as well as programmed cell death ligand 1 expression in tumor specimen as a predictive or prognostic biomarker in osteosarcoma patients.
The study is to investigate the efficacy and safety of apatinib for the first-fine treatment in elderly patients with locally advanced or metastatic adenocarcinoma of stomach or gastroesophageal junction, unable or unwilling to chemotherapy, through progression-free survival (PFS). Apatinib will be given to patients with an efficacy assessment of stable disease (SD), partial response (PR), or complete response (CR) every 2 cycles. Patients were assigned to 500 mg/d apatinib continually until disease progression or intolerable toxicity or patients withdrawal of consent. The dose of apatinib may be decreased to 250 mg/d following the occurrence of a clinically significant adverse event (AE). Treatment will be discontinued if the subject is unable to tolerate a daily dose of 250 mg, and the sample size is about 30 individuals. Tumor tissue samples will be collected from each enrolled subjects before the start of treatment, and detected using next generation sequencing (NGS)-based comprehensive genomic profiling. The potential biomarkers in predicting apatinib efficacy or safety will be explored.
This study aims to develop the quantitative biomarker to establish the individualized strategy in stroke rehabilitation. Brain-derived neurotrophic factor (BDNF) acts on certain neurons of the central nervous system (CNS) helping to support the survival of existing neurons, and encourage the growth and differentiation of new neurons and synapses. BDNF in CNS can be assessed by analysing serum BDNF. The final objective of this study is to demonstrate a role of biomarker of BDNF in stroke rehabilitation to establish the individualized strategy.
DNA biomarkers in urine are important diagnostic and prognostic indicators for bladder cancer. Many genetic alterations have been identified in the urinary DNA. However, not all bladder tumors harbor mutations in the most commonly altered oncogenes. Thus, to reach satisfactory sensitivity and specificity a new diagnostic test should include multiple biomarkers. The investigators will conduct a prospective evaluation of a panel of mutations in urine-DNA test for the detection of urothelial bladder carcinoma in patients with gross hematuria for cystoscope.
The purpose of this study is based on the Flutemetamol-PET senile plaque imaging to investigate the peripheral blood biochemical and brain MRI imaging biomarkers and to research completely independent intellectual property rights neuropsychological test tool for the MCI due to AD. At the same time, the investigators will study the efficacy and safety of early treatment of MCI due to AD by Huperzine A in 52 weeks.
Efforts to identify circulating factors that predict severity of acute lung injury/acute respiratory distress syndrome（ALI/ARDS） patients is unrevealing. The primary purpose of this study is to verify our hypothesis that soluble CD74 might be a potential novel ALI/ARDS biomarker.
The aim of this project is therefore to explore on the clinical significance of analyzing surrogate markers combined with conventional diagnostics in the ICU setting. BAL, blood and biopsy samples will be subjected to a combined analysis of GM, BDG, Aspergillus specific PCR assays in addition to conventional diagnostics (Microscopy, Culture,Histology) for ICU pts with pulmonary infiltrates. As GM and BDG are not species-specific, three established and repeatedly published species specific PCR-based assays (nested PCR, real time PCR assay, multifungal DNA Array)developed by our group will be investigated in combination with the serological tests in a multicenter prospective clinical diagnostic trial.
COACT registry is a multicenter registry of consecutive patients undergoing coronary stent implantation at 8 centers in the Catholic University of Korea to evaluate the real world management of patients with coronary artery disease and to assess their in-hospital, medium and long-term outcomes.
The purpose of this study is to assess the safety and tolerability of multiple doses of VB-201 administered for 4 weeks and its efficacy on biomarkers.
