[The structure of stroke and the effect of somatic and addiction diseases on its appearance and course in patients with HIV infection].

Objective: To study the contribution of somatic and addiction diseases to the formation and course of acute cerebrovascular accidents in people with HIV infection.

Material And Methods: The study included 123 patients with HIV infection, aged 27 to 86 years, who were treated in the primary vascular departments of hospitals in the Tyumen region in the period from 2013 to 2019. The patients were divided into two groups corresponding to the typology of stroke.

A QCM-based rupture event scanning technique as a simple and reliable approach to study the kinetics of DNA duplex dissociation.

Rupture Event Scanning (REVS) is applied for the first time within an approach based on dynamic force spectroscopy. Using model DNA duplexes containing 20 pairs of oligonucleotides including those containing single mismatches, we demonstrated the possibility of reliable determination of the kinetic parameters of dissociation of biomolecular complexes: barrier positions, the rate constants of dissociation, and the lifetime of complexes. Within this approach, mechanical dissociation of DNA duplexes occurs according to a mechanism similar to unzipping.

Clinical case of successful treatment of internal carotid artery dissection during aneurysm embolization in acute period of subarachnoid hemorrhage.

Artery dissection during embolization of an intracranial aneurysm is not a frequent complication. In most cases, the tactics of treatment are limited to the appointment of anticoagulants or balloon angioplasty. We present a clinical case of successful treatment of a woman of 47 years.

Simultaneous internal carotid artery stenosis and ipsilateral anterior communicating artery saccular aneurysm treatment: a case report.

The presence of ipsilateral aneurysm in the stenosis of the internal carotid artery is determined by computed tomography angiography in 1.8%-3.2% of cases.
