Abstract:

Kidney transplants from both living-related (LRD) and living unrelated (LURD) donors have superior function and survival than transplants from cadaver donors. This may be unsurprising as kidneys from living donors are procured under optimal conditions, from healthy donors with minimal ischaemia times. In contrast, cadaver kidneys are obtained from traumatised donors and may experience extended periods of cold ischaemic storage before transplantation. An immunohistochemical analysis has been performed on biopsies obtained before, and immediately after transplantation, to investigate the potenti

Abstract:

Cardiac injury is increased following ischemia-reperfusion. Mitochondria are the “effector organelles” that are damaged during ischemia (ISC) when there is no blood flow. Resumption of metabolism by damaged mitochondria during reperfusion (REP) results in increased cell injury. Current therapeutic interventions to pre-condition and post-condition the heart during ISC are ineffective during certain conditions like aging and diabetes due to defects in the signaling cascades. In contrast, mitochondrial-based strategies are effective in protecting the heart during ISC-REP. Hence direct therapeutic

Abstract:

Introduction: New chemotherapy regimens and improvements in surgical technique have increased the number of patients with liver tumours eligible for curative liver resection. There is a significant risk of bleeding during liver surgery, but this risk can be reduced if the portal inflow is temporarily closed; i.e. the Pringles maneuver (PM). If the PM is used, the liver will suffer from ischemia and reperfusion injury (IRI). If the liver remnant is too small or if the patient has chronic liver disease, the IRI may inhibit the regeneration of the liver remnant. The patient may then die from post

Abstract:

Introduction: During the last two decades, liver surgery has expanded enormously, partly due to improved surgical equipment and techniques as well as new and more powerful chemotherapy agents. As the liver is a very well-vascularized organ, there is an inherent risk of bleeding during liver resection. One of the most popular methods employed to reduce this risk is to close the vascular inflow to the liver using the Pringle’s maneuver (PM). However, this procedure has been recognized to cause ischemia/reperfusion injury (IRI) to the future liver remnant (FLR). In cases of extensive resection wh

Abstract:

Restoring cerebral blood flow using reperfusion treatment is a common method in treating ischaemic stroke. Reperfusion treatment should be given within 4.5 hours from stroke onset. However, reperfusion beyond this time window poses the risk of reperfusion injuries such as intracranial haemorrhage and cerebral tissue swelling. The focus of this thesis is to study the effect of cerebral tissue swelling after reperfusion as it can occur in a few hours after the treatment. Cerebral tissue swelling may cause brain structure movement and cerebral microvessel compression; the latter may then lead to

Abstract:

Coronary artery disease limits myocardial blood flow and results in myocardial infarction. Reperfusion therapies restore coronary flow, but may also cause myocardial ischemia reperfusion injury (MIRI). Multiple critical factors contribute to MIRI and among them, oxidative stress plays an important role. This burst of oxidative stress during reperfusion is caused by a variety of sources which collectively are called reactive oxygen species (ROS). Peroxynitrite is more cytotoxic than other ROSs, which at high concentration serves as a detrimental molecule with a variety of target. Peroxynitrite

Background - Ischaemia/reperfusion accounts for a large proportion of fatalities in the developed world. Even if death is avoided, the patient suffers a deterioration in their quality of life.

Ischemia-reperfusion injury (IRI) is a major cause of acute kidney injury in both native kidneys and renal allografts.

Src kinases are necessary and sufficient for upregulation of EphA2. We have proposed that IRI-induced EphA2 upregulation may serve as a necessary step in renal tubular remodelling.<br>In this study, we have further defined the mechanism of Src kinase-i

CaMKII acts as a second messenger to Ca2+ signals within the cardiac myocyte. Cellular stresses such as ischaemia and subsequent reperfusion perturb the normal physiological oscillations of Ca2+ to cause an escalating concentration which damages the cell. CaMKII has been implicated as an injury signal during such cellular conditions. However, there are discrepancies as to whether CaMKII is a possible mechanism of ischaemic preconditioning as its inhibition can abrogate or improve the protective effect of preconditioning.
