Relationship between the Levels of mRNA Expression for Protein Phosphatase 1B and Proteins Involved in Cytoskeleton Remodeling in Squamous Cell Carcinoma of the Larynx and Hypopharynx.

We analyzed the expression of genes encoding proteins involved in cytoskeleton remodeling (RND3, SNAI1, vimentin, cofilin, adenylate cyclase-associated protein 1, ezrin, and profilin) depending on the level of expression of protein phosphatase 1B (PPM1B) mRNA on the example of squamous cell carcinoma of the larynx and hypopharynx. Against the background of a high level of PPM1B expression, a significantly high level of profilin expression was noted. Metastasis correlated with the level of snai1 expression, while relapse after combination treatment was negatively associated with the level of vimentin expression.

[Chemoradiotherapy in combination with local hyperthermia for patients with non-small cell lung cancer].

Short-term treatment outcomes for 15 patients with stage IB-III non-small cell lung cancer (NSCLC) were present- ed. The patients were treated with thermochemoradiothrapy (TCRT). Hyperfractionated radiation therapy at a total dose of 40 Gy (1.

[Background Level of γH2AX Foci in Human Cells as a Factor of Individual Radiosensitivity].

The paper analyzes the effects of spontaneous level of yH2AX and 53BP1 foci on a frequency of radiation-induced centromere-negative and centromere-positive micronuclei in peripheral blood lymphocytes of 54 healthy individuals after exposure to 2 Gy of ionizing radiation in vitro. An inverse correlation was found between the level of spontaneous yH2AX foci and the frequency of centromere-negative micronuclei after irradiation. The corresponding correlations between the spontaneous level of protein 53BP1 foci and the frequency of centromere-negative micronuclei were not statistically significant.

[Fast neutrons 6.3 MeV in the combined treatment of patients with local recurrence of breast cancer].

The article is devoted to the problem of treatment of patients with locally advanced breast cancer recurrences as well as a study of neutron therapy influence on normal tissues and various critical organs. The use of fast neutrons of 6.3 MeV in these patients is often the only treatment option.

[Ozone therapy for radiation reactions and skin lesions after neutron therapy in patients with malignant tumors].

The article discusses the problem of radiation complications from normal tissues in patients after therapy with fast neutrons of 6.3 MeV. The methods of treatment using ozone technologies in patients with radiation reactions and skin lesions on the areas of irradiation after neutron and neutron-photon therapy have been worked out.

Cytogenetic effects of neutron therapy in patients with parotid gland tumors and relapse of breast cancer.

Aim: To assess the frequency and spectrum of chromosome aberrations and micronuclei in peripheral blood lymphocytes of patients with parotid salivary gland tumors and relapse of breast cancer during the course of neutron therapy.

Materials And Methods: Samples of peripheral blood were obtained from 9 patients with parotid salivary gland tumors (T3N0-3M0) and 8 patients with relapse of breast cancer before, after first fraction and at the end of neutron therapy. The treatment course specified 5.
