Early in the development of the heart, the single heart tube consists of the inner and outer tubes,the endocardium, and myocardium, respectively, which are separated by an extracellular matrix secretedby the myocardial cells and termed cardiac jelly. This extracellular matrix promotes the tubularlumen during contraction and acts as a site for the deposition of inductive factors from the myocardialcells which can modify the differentiation of specific endocardial cells...

The Caspian miniature horse is one of the rare small breeds in the north of Iran.  In the present study, the position of the heart and its valves were determined  topographically in 4 miniature horses....

Double outlet right ventricle (DORV) is a complex group of abnormal ventriculoarterial  connections where both the aorta and  pulmonary artery rise from the  right ventricle morphologically. It is a rare condition affecting 1–1.5% of patients  with congenital heart disease.  The patient’s cardiac measurements were taken by two-dimensional echocardiography...

The incidence of primary malignant tumor of the heart is extremely low: about 0.02% in a series of autopsies [1, 2]. The incidence among the general population varies between 0.001% and 0.03% [3]...

Coronary artery disease is a leading cause of death worldwide. The main pathological manifestation of coronary artery disease is myocardial damage due to ischemia-reperfusion injury [1]. Clinically, myocardial ischemia-reperfusion relates to conditionssuch as myocardial infarction, coronary angioplasty, thrombolytic therapy, coronary revascularization and heart transplantation [2]...

Sudden unexpected death in epilepsy (SUDEP) is defined as sudden, unexpected, witnessed or unwitnessed, non-traumatic and non-drowning deaths in patients with epilepsy, with or without evidence of a seizure and excluding documented status epilepticus, in which a post-mortem examination does not reveal a toxicological or anatomical cause of death [1]. The incidence of SUDEP has been estimated from 0.5–1.4/1,000 person-years in people with treated epilepsy, and 9/1,000 person-years in candidates for epilepsy surgery [2]...

Populacja pacjentów z przewlekłą chorobą nerek (CKD, chronic kidney disease) charakteryzuje się wysokim ryzykiem zachorowania na schorzenia układu krążenia oraz wysoką śmiertelnością w ich następstwie. Analiza przebiegu i rokowania CKD wskazuje również na fakt, że istnieje ścisły związek między zaawansowaną chorobą nerek i wielkością ryzyka powikłań sercowo-naczyniowych, prowadzący do sytuacji, w której ryzyko to wzrasta w miarę pogłębiania się uszkodzenia nerek...

Although the septomarginal trabecula is a well-known anatomical structure, there continue to be different ways of studying it. In this study, we dissected the muscle bundles that form it, and this has enabled us to present a new classification based on the origin, path, and termination of these bundles...

The aim of the study was to organise an assessment of the physical strains and environmental exposure to hydrocarbon derivatives in persons involved in shoreline clean-up of heavy oil products, in order to investigate the dangers of oil spill clean-up.

Knowledge of morphometric quantities of coronary arteries in infants is an increasingly vital component in managing congenital and acquired heart disease. Because of considerable heterogeneity of coronary vasculature, what is considered atypical and aberrant or insignificant anatomy is often unclear.
