Epidemiological studies suggest that acute kidney injury has certain effect on myocardial function. In this study, for the first time, we tested a boron compound namely lithium tetraborate an act as anti-oxidant and anti-inflammatory agent in ischemia-reperfusion injury. For this, employed vivo rat model with ischemia reperfusion to evaluate cardiac clarify mechanisms of tetraborate. The evalua...

BACKGROUND AND PURPOSE Remote ischemic preconditioning is a phenomenon by which a short period of sublethal ischemia to an organ protects against subsequent ischemia in another organ. We have recently demonstrated that remote ischemic conditioning by transient hind limb ischemia delivered during ischemia and before reperfusion can provide potent cardioprotection, a phenomenon we termed per-cond...

Background Oxidative stress and autophagy both play key roles in continuous cardiomyocyte death and cardiac dysfunction after reperfusion therapy for acute myocardial ischemia-reperfusion injury. Coenzyme Q10 (CQ10), which is a fat-soluble quinone antioxidant, is involved in the pathophysiological processes of neurodegenerative diseases, cancer, diabetes, heart failure, and other diseases. Our ...

BACKGROUND AND PURPOSE Thrombolytic therapy is not recommended in patients with CT changes of recent major infarction, which has been defined as reduced attenuation or cerebral edema involving >33% of the middle cerebral artery territory (European Cooperative Acute Stroke Study [ECASS] criteria). Diffusion-weighted imaging (DWI) is more sensitive than CT in detecting acute ischemia, and the com...

Normobaric hyperoxia (NBO) and cilostazol (6-[4-(1-cyclohexy-1H-tetrazol-5-yl)butoxyl]-3,4-dihydro-2-(1H)-quinolinone) (a selective inhibitor of phosphodiesterase 3) have each been reported to exert neuroprotective effects against acute brain injury after cerebral ischemia in rodents. Here, we evaluated the potential neuroprotective effects of combination treatment with NBO and cilostazol again...

A fundamental aspect of acute renal ischemia is energy depletion, manifest as a falling level of ATP that is associated with a simultaneous rise in AMP. The energy sensor AMP-activated protein kinase (AMPK) is activated by a rising AMP-to-ATP ratio, but its role in acute renal ischemia is unknown. AMPK is activated in the ischemic heart and is reported to phosphorylate both endothelial nitric o...

The data from this study document that dobutamine is a powerful inotropic agent in anesthetized dogs with acute myocardial ischemia and in awake, unsedated ones with chronic myocardial infarction. Dobutamine significantly increases heart rate at relatively small doses in anesthetized dogs with acute myocardial ischemia but considerably larger amounts of dobutamine are required to significantly ...

Male and female, arteriosclerotic (breeder) and nonarteriosclerotic (virgin), Sprague-Dawley rats were made severely diabetic with alloxan. Two weeks later experimental animals had both carotid arteries ligated to induce a state of acute cerebral ischemia. After six weeks of cerebral ischemia either with or without severe diabetes the animals were killed. Animals which survived either the acute...

BACKGROUND AND OBJECTIVES Mesenteric ischemia which can be acute or chronic depending on the rapidity of compromised blood flow produces bowel ischemia, infarction, bacterial transmigration, endotoxemia, multisystem organ failure and death. High altitude can precipitate thrombosis because of hypobaric hypoxia and its effect on coagulation system. The objectives of this study are to determine th...

Introduction. Severe acute respiratory syndrome coronavirus 2 infection-induced coagulopathy may be the underlying cause of limb ischemia, a sudden decrease in perfusion. The aim this study was to present case series ischemia associated with severe infection. Material and Methods. This unicentric, observational cohort evaluated incidence, risk factors, clinical, laboratory radiological findings...
