Introduction: Reactive oxygen species (ROS) have been suggested to play an important role in the myocardial damage induced by ischemia – reperfusion. One element believed to be activated by ROS and to contribute to the reduction of ROS production, is the uncoupling protein-2 (UCP2). The objective of this investigation was to explore the effect of myocardial ischemia reperfusion on cardiac UC...

today, with emphasis on the mechanical heart and heart transplantation from one human to another andone species to another, a knowledge of the anatomy of the bird’s heart could contribute to theseaccomplishments. eight male adult ostriches were used to study the heart macroscopically. this studyrevealed that the ostrich heart has some different features from the other birds. in the ostrich, fib...

an experiment was conducted in which 30 broiler chickens were selected based on their ecg and designated as healthy or subclinical ascites. subsequently, blood samples were collected and assayed for hemoglobin, hematocrit and differential leukocyte count. finally, all the birds were euthanized and their hearts harvested for the ventricle cuts. results indicated that broilers with subclinical as...

Endocardial fibroelastosis in neonates with hypoplasia of the left ventricle is usually associated with severe aortic stenosis or atresia. In this study three hearts were examined, in which severe hypoplasia of the left ventricular cavity with myocardial hypertrophy and endocardial fibroelastosis were associated with small but non-stenotic subaortic outflow tracts and aortic valves. These featu...

A 12-lead ECG was obtained soon after the birth of a pair of omphalo-thoracopagus (Figure 1) conjoined twins. Before birth, they had been diagnosed with two separate hearts that shared a wide communication through the independently defined right atria. Other anomalies including a common liver with two gallbladders and two stomachs with common jejunum and ileum beyond the duodenum were also note...

OBJECTIVE.Our goal was to determine whether the third ventricle is significantly enlarged among neonates with trisomy 21, compared with infants without clinical signs of trisomy 21. This enlargement might be related to hypoplasia of the structures surrounding the third ventricle. These structures participate in cognitive development, and hypoplasia in this area may be responsible for some of th...

Premature closure or restriction of foramen ovale (PCFO) is a rare congenital anomaly that can lead to a wide spectrum of cardiac malformations. This spectrum of secondary malformations appears to depend on the gestational timing of closure of the foramen ovale and to the degree of restriction. Earlier in the gestation, closure of the foramen has been associated with severe hypoplasia of the le...
