Filter by:Remote ischemia precondition could protect the liver from ischemia reperfusion injury in patients undergoing hepatectomy.
Vocal stimulation may encourage spontaneous breathing in patients dependent on mechanical ventilation. The study will include 30 patients on mechanical ventilation that will be intervened by the vocal stimulation and 30 patients on mechanical ventilation will serve as the control group.
The aim of the present study is to investigate safety and efficacy of intramyocardial implantation of allogeneic mesenchymal stem cells in patients with ischemic cardiomyopathy .
1. Cardiopulmonary bypass and cardioplegic arrest could regulate expression of microRNAs in patients undergoing double valve replacement (aortic and mitral). 2. The modulation of myocardial microRNAs by cardiopulmonary bypass and cardioplegic arrest may be rescued by ischemic postconditioning. 3. Downstream effectors would also be affected.
The investigators expect to find higher levels of both classical and minor antiphospholipid (APL) antibodies among the stroke cases. Furthermore, the investigators expect to find not only classical APLA but also minor antibodies. The investigators believe that minor antibodies have a major role in the hypercoagulability state.
Using autologous bone marrow mononuclear cells (BM-MNC) to treat patients with chronic limb ischemia has been proved safe and effective. However, processing bone marrow by Ficoll density gradient centrifugation is not only time consuming but also expensive. Manually processing of bone marrow also results in large variation in therapeutic cell quantity and quality which directly leads deviation of safety and efficacy of the cell therapy. This study is aiming to compare an automated bone marrow processing system with a conventional manual method in term of safety and efficacy.
The purpose of the study is to determine the safety and possible effectiveness of brain transplants of CD34+ stem cells obtained from umbilical cord blood (UCB) to treat stroke.
Previous research has shown there wasn't inevitable relationship between mismatch area and infarct growth according to Volumetric-subtraction mismatch volume.The recently published on Stroke paper has proposed Coregistration mismatch to calculate the mismatch to replace ischaemic penumbra, and it reignites hope for clinical application of the PWI/DWI mismatch. But the correlation between the mismatch, calculated by Coregistration mismatch method,and the clinical outcome of the patients with acute ischemic stroke is still unknown. so the investigators plan to conduct a prospective observational cohort study.
This will be a randomized, double-blind, placebo-controlled, multi-center, multi-national, escalating dose, pilot study comparing two doses of THR-18 to placebo when administered to patients suffering acute ischemic stroke and treated with Tissue Plasminogen Activator (tPA). The study hypothesis is that THR-18 will be safe and well tolerated in subjects suffering acute ischemic stroke and treated with Thrombolysis.
The aim of this study is to evaluate the effects of remote ischemic preconditioning on cognitive function in patients undergoing off-pump coronary artery bypass graft.
