Development of a Protocol for Obtaining a Homologous Cell Product of Animal Origin Intended for Preclinical Studies of Antitumor Vaccine CaTeVac.

When developing a program of preclinical studies of human cell-based drugs intended for adoptive immunotherapy of cancer patients, the biological effect should be substantiated by data describing their immunological action. Administration and study of human autologous dendritic cell vaccine to immunocompetent animals are not adequate in terms of immunological compatibility. It is possible to use immunocompromised, knockout, or transgenic animals or to obtain a homologous cellular product, namely, a preparation based on animal cells using a technology similar to obtaining the original preparation for clinical practice in humans.

Artificial intelligence for early diagnosis of lung cancer through incidental nodule detection in low- and middle-income countries-acceleration during the COVID-19 pandemic but here to stay.

Although the coronavirus disease of 2019 (COVID-19) pandemic had profound pernicious effects, it revealed deficiencies in health systems, particularly among low- and middle-income countries (LMICs). With increasing uncertainty in healthcare, existing unmet needs such as poor outcomes of lung cancer (LC) patients in LMICs, mainly due to late stages at diagnosis, have been challenging-necessitating a shift in focus for judicious health resource utilization. Leveraging artificial intelligence (AI) for screening large volumes of pulmonary images performed for noncancerous reasons, such as health checks, immigration, tuberculosis screening, or other lung conditions, including but not limited to COVID-19, can facilitate easy and early identification of incidental pulmonary nodules (IPNs), which otherwise could have been missed.

[Staged treatment of patients with lymphedema of the lower extremities].

At examination of 120 patients with lymphedema of the lower extremities, in 70% of them, structure and function of lymphangion were preserved. State of lymphangion is of great importance in substantiation of the tactics of treatment. In preserved morphofunctional properties of lymphangion, the operation of lymphovenous shunting is effective in 83% of the patients.

[Relation between interleukin-2 production and the time of irradiation and mitogenic lymphocyte activation].

The effect of radiation on the production of interleukin 2 by activated lymphocytes was shown to be a function of time interval between irradiation and mitogen stimulation of cells. The most intensive production of interleukin 2 was noted in cells exposed 24 h following the effect of the mitogen. The enhancing effect of in vivo irradiation was less pronounced.
