OBJECTIVE
Myocardial ischemia is accompanied by a rapid activation of adenosine-monophosphate-activated protein kinase (AMPK). However, it is unclear whether this represents a potentially beneficial or detrimental event in the course of ischemic injury. The role of AMPK activation in the
The aim of the present study was to assess the effect of post ictal administration of the pyrrolopyrimidine lipid peroxidation inhibitor, U-101033E, on infarct volume and neuronal and astrocytic metabolism in rats with transient middle cerebral artery occlusion (MCAO). Rats were subjected to 120 min
To investigate the effect of Yiqihuoxue prescription (YQHX) from Traditional Chinese Medicine (TCM) on myocardial glucose and lipid metabolism after myocardial infarction via the cross talk between the liver kinase B1 (LKB1)-dependent Notch1 and adenosine 5'-monophosphate OBJECTIVE
Myocardial infarction (MI) is a cause of high morbidity and mortality in the world. Sodium tanshinone IIA sulphonate (STS) has been well used in Oriental medicine for treating cardiovascular diseases, however, the underlying mechanisms remain unclear. Alterations of circulating lipid
BACKGROUND
Diabetes increases the morbidity/mortality of ischemic heart disease, but the underlying mechanisms are incompletely understood. Deficiency of both AMP-activated protein kinase (AMPK) and adiponectin occurs in diabetes, but whether AMPK is cardioprotective or a central mediator of
Abnormally high rates of fatty acid metabolism is an important contributor to the severity of ischemic heart disease. During and following myocardial ischemia a number of alterations in fatty acid oxidation occur that result in an excessive amount of fatty acids being used as a fuel source by the
BACKGROUND
Overeating and obesity are major health problems in developed countries. Caloric restriction (CR) can counteract the deleterious aspects of obesity-related diseases and prolong lifespan. We have demonstrated that short-term CR improves myocardial ischemic tolerance and increases
Unacylated ghrelin (UAG), the most abundant form of ghrelin in circulation, has been shown to exert cardioprotective effect in experimental cardiopathies. The present study aimed to investigate the cardioprotective effect of a linear bioactive fragment of UAG against myocardial ischemia-induced
AMP-activated protein kinase (AMPK) protects various tissues and cells from ischemic insults and is activated by many stimuli including mechanical stretch. Therefore, this study investigated if the activation of AMPK is involved in stretch-induced cardioprotection (SIC). Intraventricular balloon and
BACKGROUND
Propionic acidaemia (PA) results from deficiency of Propionyl CoA carboxylase, the commonest form presenting in the neonatal period. Despite best current management, PA is associated with severe neurological sequelae, in particular movement disorders resulting from basal ganglia
Punicalagin (PUN), a major bioactive component in pomegranate juice, has been proven to exert neuroprotective effects against cerebral ischemia/reperfusion (I/R) insult via anti-oxidant properties. This study aims to investigate whether PUN provides cardioprotection against myocardial I/R (MI/R)
It was previously shown that total saponins extracted from Aralia taibaiensis (sAT) have potent antioxidant activities for treating diabetes mellitus and attenuate d-galactose-induced aging. Since diabetes mellitus and aging are closely associated with cardiac dysfunction, particularly ischemic
Obesity is a critical risk factor for various diseases including type II diabetes, cerebral infarction, cardiovascular diseases, and various cancers. Acrylamide (ACR) is present in wide range of foods, including fried potato products, root vegetables, bakery products, chips, cakes, cereals, and
Chronic heart failure affects myocardial energy metabolism and cardiac function. Puerarin has been reported to improve cardiac function through regulation of energy metabolism in mice with myocardial infarction. The aim of the current study was to determine whether puerarin can improve body weight
UNASSIGNED
A longevity gene, Sirtuin 1 (SIRT1) and energy sensor AMP-activated protein kinase (AMPK) have common activators such as caloric restriction, oxidative stress, and exercise. The objective of this study is to characterize the role of cardiomyocyte SIRT1 in age-related impaired ischemic
