Surgical Repair of a Rare Variant of Common Arterial Trunk, With Considerations of its Significance for Morphogenesis.

We present a successful surgical repair of a rare variant of the common arterial trunk with unusual arrangement of the pulmonary arteries. The variant was not readily classified using either of the popular classifications for the common arterial trunk. It is appropriately described as a common arterial trunk showing aortic dominance, but with extrapericardial origin of the pulmonary arteries from the underside of the truncal arch.

Retained bullet in the neck after gunshot wounds to the chest and arm in combat patient injured in the war in Ukraine: A case report.

Introduction And Importance: A gunshot wound is the most common injury in armed conflicts, resulting in severe trauma and increased morbidity usually due to damage to major vessels. Gunshot injury could be associated with the projectile location in one anatomical area, but the initial inlet place in another.

Presentation Of Case: A 33-years old male patient received gunshot injuries to the left axillary area of the chest and left upper extremity in the battlefield area near Kyiv (Ukraine).

An Alternative Approach for a High Partially Anomalous Pulmonary Venous Connection to the Superior Vena Cava: "A Drawbridge Technique".

We present an alternative technique for the repair of a high partially anomalous pulmonary venous connection to the superior vena cava.

Nanomechanical and Nanotribological Properties of Nanostructured Coatings of Tantalum and Its Compounds on Steel Substrates.

The present paper addresses the problem of identification of microstructural, nanomechanical, and tribological properties of thin films of tantalum (Ta) and its compounds deposited on stainless steel substrates by direct current magnetron sputtering. The compositions of the obtained nanostructured films were determined by energy dispersive spectroscopy. Surface morphology was investigated using atomic force microscopy (AFM).

Comparison of LPO-AOS Indices and Biochemical Composition of Animal Blood in Biogeochemical Provinces with Different Levels of Selenium.

The paper aims to compare parameters of lipid peroxidation and antioxidant defense system, as well as blood biochemical composition in infertile cows from groups that differ in terms of selenium content in agrocoenosis. Forty-five black-motley and red-motley breeds in each region were selected for the experiment; the groups were formed on the basis of the pathology, 15 animals each. The level of microelements in the blood of animals from all groups in the selenium-deficient biogeochemical province is significantly reduced by 38.
