Radiation-induced heart disease (RIHD) is a potentially severe side effect of radiotherapy of thoracic and chest wall tumors if all or part of the heart was included in the radiation field. RIHD presents clinically several years after irradiation and manifestations include accelerated atherosclerosis, pericardial and myocardial fibrosis, conduction abnormalities, and injury to cardiac valves. T...
Extracellular ATP acts on purinergic receptors as a potent agonist for a variety of different cell types, including cardiomyocytes and nodose ganglia. P2X3 receptor is the most abundant P2X-receptor subtype in heart and nodose ganglia. This study wants to observe the role of P2X3 receptor in myocardial ischemic injury and nociceptive transmission via nodose ganglia. The serum lactate dehydrogen...
The zebrafish has the capacity to regenerate its heart after severe injury. While the function of a few genes during this process has been studied, we are far from fully understanding how genes interact to coordinate heart regeneration. To enable systematic insights into this phenomenon, we generated and integrated a dynamic co-expression network of heart regeneration in the zebrafish and linke...
background: accidents are the second reason for mortality and morbidity in iran. among them, brain injuries are the most important damage. clarification of the effects of brain injuries on different body systems will help physicians to prioritize their treatment strategies. in this study, the effect of pure brain trauma on the cardiovascular system and lungs 24 hours post trauma was assessed. m...
To mimic ischemic heart disease in humans, several animal models have been created, mainly in rodents by surgically ligating their coronary arteries. In the present study, by simply inducing burn injuries on the bullfrog heart, we reproduced abnormal ST segment changes in the electrocardiogram (ECG), mimicking those observed in ischemic heart disease, such as acute myocardial infarction and ang...
BACKGROUND Neurodevelopmental delays in motor skills and white matter (WM) injury have been documented in congenital heart disease and after pediatric cardiac surgery. The lack of a suitable animal model has hampered our understanding of the cellular mechanisms underlying WM injury in these patients. Our aim is to identify an optimal surgical strategy for WM protection to reduce neurological in...
BACKGROUND The factors contributing to chronic Chagas' heart disease remain unknown. High nitric oxide (NO) levels have been shown to be associated with cardiomyopathy severity in patients. Further, NO produced via inducible nitric oxide synthase (iNOS/NOS2) is proposed to play a role in Trypanosoma cruzi control. However, the participation of iNOS/NOS2 and NO in T. cruzi control and heart inju...
