conclusions the pattern of pretreatment with o2 could change this potential and highly protective strategy against cp-induced nephropathy to an ineffective or even mildly deteriorating one. therefore, o2 administration before cp injection to patients with cancer, for therapeutic purposes or as a preconditioning approach, should be performed and investigated with caution until exact effects of d...
OBJECT Preconditioning with hyperbaric oxygen (HBO2) reduces ischemic brain damage. Activation of p44/42 mitogen-activated protein kinases (p44/42 MAPK) has been associated with preconditioning-induced brain ischemic tolerance. This study investigated if preconditioning with HBO2 protects against intracerebral hemorrhage (ICH)-induced brain edema formation and examined the role of p44/42 MAPK i...
aim and background: remote ischemic preconditioning introduces brief episodes of ischemia and reperfusion which reduces long term ischemia in orthopaedic surgery. the aim of this study was to evaluate hemodynamic and respiratory effects of remote ischemic preconditioning in lower extremity orthopaedic surgeries. methods: in this clinical trial 40 patients scheduled for lower extremity surgery w...
objective(s):this study aimed to examine the hypothesis that an antiarrhythmic effect might be obtained by ischemic preconditioning of the liver, and also to characterize the potential underlying mechanisms. materials and methods: male wistar rats were anesthetized by thiopental sodium (50 mg/kg, ip) followed by iv injection of heparin (250 iu). remote ischemic preconditioning (ripc) was induce...
the ability to optimize muscular power output is considered as a basis for successful performance in the most sports. the aim of this study was to investigate changes in dynamic exercise performance following a sequence of preconditioning isometric muscle actions. twelve nonathlete, active female volunteers (age: 16±1 yr, height: 162±6.34 cm, weight: 60±9.21 kg) participated in the present stud...
The initial discovery of cardiac preconditioning has evolved into an exciting series of practical surgical applications. An enormous amount of evidence demonstrating both the safety and efficacy of ischemic preconditioning is available from animal studies. The challenging premise of intentionally subjecting patients and their organs to transient ischemia has acted as a formidable psychological ...
PURPOSE The objectives of this study were to examine whether preconditioning can decrease ischemic damage to the retina, by electroretinographic assessment of visual function and by histologic examination of retinal structure; to investigate the time course of the effectiveness of preconditioning; and to determine whether protein synthesis is involved. METHODS Retinal ischemia was produced fo...
A taste sensor that uses lipid/polymer membranes can evaluate aftertastes felt by humans using Change in membrane Potential caused by Adsorption (CPA) measurements. The sensor membrane for evaluating bitterness, which is caused by acidic bitter substances such as iso-alpha acid contained in beer, needs an immersion process in monosodium glutamate (MSG) solution, called "MSG preconditioning". Ho...
PURPOSE Brief ischaemic episodes, followed by periods of reperfusion, increase the resistance to further ischaemic damage. This response is called "ischaemic preconditioning." By reviewing the molecular basis and fundamental principals of ischaemic preconditioning, this paper will enable the anaesthetic and critical care practitioner to understand this developing therapeutic modality. SOURCE ...
conclusions our data suggest that preconditioning with 5 μm h2o2 + 0.5% fbs and 10 μm h2o2 + 5% fbs improved cell proliferation and viability. however, the mechanisms related to protective properties of preconditioning and using this strategy in stem cell therapy requires more research. background mesenchymal stem cells (mscs) survival decreased following in vivo injection and its application h...
