[MALIGNANT NEOPLASMS OF THE REPRODUCTIVE SYSTEM IN MEN AND THEIR CONNECTION WITH THE HUMAN PAPILLOMAVIRUS. (REVIEW)].

The issue of malignant tumor occurrence associated with viral infections is a particularly significant one. Approximately 15-20% of tumors have some connection with various viral infections. An extensive amount of data has been gathered on neoplasms of the female reproductive system linked to the human papillomavirus (HPV).

Pressure-tuning of α-RuCl towards a quantum spin liquid.

The layered material α-RuCl is a promising candidate to realize the Kitaev quantum spin liquid (QSL) state. However, at ambient pressure, deviations from the perfect Kitaev geometry prevent the existence of the QSL state at low temperatures. Here we present the discovery of a pressure-induced high-symmetry phase in α-RuCl, which creates close to ideal conditions for the emergence of a QSL.

Use of Adjuvant Compositions Based on Squalene Ensures Induction of Neutralizing Antibodies against SARS-CoV-2.

Squalene-based adjuvant compositions that can provide effective induction of specific humoral immune response have been developed. Recombinant receptor-binding domain (RBD) of surface S-protein of SARS-CoV-2 was used to evaluate the properties of the composition. Immunization of mice with the developed squalene-based compositions in combination with RBD allows obtaining high titers of specific antibodies: from 10 to 2×10.

Ubiquitous Order-Disorder Transition in the Mn Antisite Sublattice of the (MnBiTe)(BiTe) Magnetic Topological Insulators.

Magnetic topological insulators (TIs) herald a wealth of applications in spin-based technologies, relying on the novel quantum phenomena provided by their topological properties. Particularly promising is the (MnBiTe)(BiTe) layered family of established intrinsic magnetic TIs that can flexibly realize various magnetic orders and topological states. High tunability of this material platform is enabled by manganese-pnictogen intermixing, whose amounts and distribution patterns are controlled by synthetic conditions.

Significance of Hypoalbuminemia in the Development of Thromboembolic Complications in Severe Cases of SARS-CoV-2 Coronavirus Infection.

Background: The course of coronavirus disease 2019 (COVID-19) is associated with the progression of a wide range of complications, among which thrombosis and thromboembolism are of particular importance. The significance of hypoalbuminemia in the development of thromboembolic complications (TECs) in patients with a severe course of COVID-19 is currently under active discussion. The objective of our study was to evaluate the significance of hypoalbuminemia in the development of TECs in patients with severe SARS-CoV-2 coronavirus infection.
