[Features of detection and interpretation of intravital and postmortem changes according to the results of traditional X-ray and X-ray computed tomography of objects from historical graves and artefacts].

Objective: To study emergence mechanism, physical nature, pattern of intravital and postmortem changes of biological and non-biological objects originated in the period from 1550 to 1918 yr. using traditional X-ray and X-ray computed tomography.

Material And Methods: The relics of Saint Macarius the Roman of Novgorod, the remains of the First Reverend of the Resurrection Novodevichy Convent in Saint Petersburg Mother Superior Theophania, damages on the chair leg on which Tsesarevich Alexey sat during the shooting of Russian Emperor Nicholas II, his family and entourage in 1918 in Yekaterinburg were stidued.

[Endovascular treatment of aneurysms and pseudoaneurysms of visceral arteries].

Aim: The purpose of the study was to demonstrate the possibilities and efficacy of endovascular interventions in patients with visceral artery aneurysms.

Patients And Methods: From 2013 to June 2020, we performed 15 embolizations of visceral artery aneurysms in 15 patients (8 men and 7 women). The technical success rate was 100%.

[Embolization of a pseudoaneurysm of the inferior gastroduodenal artery].

Aneurysms and pseudoaneurysms of visceral arteries are relatively rare clinical entities and their pathogenesis has not yet been fully understood. Aneurysmal rupture appears to be a complication leading to life-threatening internal haemorrhage and is a cause of high mortality. However, advances in endovascular surgery techniques have extended the capabilities of treating aneurysms, allowing microemboli to be delivered even to the hard-to-reach portions of the vascular bed with complicated anatomy.

[Chiari network and pulmonary embolism].

We present the case of a patient with acute pulmonary embolism, Chiari network thrombus, and deep vein thrombosis in lower extremities. Chiari networks are present in the right atrium in a minority of population and are usually of no clinical significance. On the other hand it may be associated with such pathological changes as patent foramen ovale, intraatrial thrombus, or atrial arrhythmias.

[Study of mycobiota in the reclaimed Nazarovo coal mine (Krasnoyarsk Krai)].

This paper presents the results of study of species diversity and certain aspects of macromycete ecology in reclaimed areas of Nazarovo coal mine. A relatively low number of species and ecological groups of fungi on the reclaimed areas were revealed.
