Mass Spectrometry of Collagen-Containing Allogeneic Human Bone Tissue Material.

The current paper highlights the active development of tissue engineering in the field of the biofabrication of living tissue analogues through 3D-bioprinting technology. The implementation of the latter is impossible without important products such as bioinks and their basic components, namely, hydrogels. In this regard, tissue engineers are searching for biomaterials to produce hydrogels with specified properties both in terms of their physical, mechanical and chemical properties and in terms of local biological effects following implantation into an organism.

3D Bioprinting of Hyaline Articular Cartilage: Biopolymers, Hydrogels, and Bioinks.

The musculoskeletal system, consisting of bones and cartilage of various types, muscles, ligaments, and tendons, is the basis of the human body. However, many pathological conditions caused by aging, lifestyle, disease, or trauma can damage its elements and lead to severe disfunction and significant worsening in the quality of life. Due to its structure and function, articular (hyaline) cartilage is the most susceptible to damage.

Adjuvant effect of high-frequency hyperthermia of the abdominal cavity on the course of transplanted leukemia in AKR mice.

The adjuvant effect of high-frequency hyperthermia of the abdominal cavity was studied in 2-month-old mice of highly leukemic AKR strain treated with cyclophosphamide. Weights of organs, parameters of the peripheral blood, and cytological imprints of organs were compared in experimental and control animals. A more pronounced antitumor effect was observed in animals exposed to hyperthermia.

Dependence of pathogenic properties of leptospires on animal subspecies.

1. Leptospires of mozdok serotype of the Pomona serogroup possessed specific pathogenic properties for a definite subspecies of Apodemus agrarius. They caused carriership in rodents of a European population, but were unable to cause such a process in Far East mice.
