Abstract
The time of stress exposure relative to the moment of immunization affects the direction of the immunoregulatory effect of stress. In case of stress exposure preceding immunization, rotation stress stimulated the production of antibodies, while immobilization depressed it. After antigen injection, these types of stress had no significant effect on the formation of antibody-producing cells. Acute cold stress did not affect the number of antibody-forming cells before immunization, but stimulated the humoral response after it. At the same time, the effect of stress on the production of antibodies was leveled by blockade of opioid receptors with naloxone for rotation and immobilization, but was not canceled for acute cold stress. A similar pattern was revealed when analyzing the effect of stress exposure on cytokine production. Cold stress before antigen administration to mice had almost no effect on the production of IL-2, IL-4, IFNγ, while rotational and immobilization stress naloxone-dependently modulated the synthesis of IL-2 and IL-4. On the contrary, in animals subjected to stress after antigen administration, only cold stress significantly modulated the production of IL-2 and IL-4.

Abstract
Photodynamic therapy (PDT) in oncology is characterized by low invasiveness, minimal side effects, and little tissue scarring. Increasing the selectivity of PDT agents toward a cellular target is a new approach intended to improve this method. This study is devoted to the design and synthesis of a new conjugate based on meso-arylporphyrin with a low-molecular-weight tyrosine kinase inhibitor, Erlotinib. A nano-formulation based on Pluronic F127 micelles was obtained and characterized. The photophysical and photochemical properties and biological activity of the studied compounds and their nano-formulation were studied. A significant, 20-40-fold difference between the dark and photoinduced activity was achieved for the conjugate nanomicelles. After irradiation, the studied conjugate nanomicelles were 1.8 times more toxic toward the EGFR-overexpressing cell line MDA-MB-231 compared to the conditionally normal NKE cells. The IC50 was 0.073 ± 0.014 μM for the MDA-MB-231 cell line and 0.13 ± 0.018 μM for NKE cells after irradiation for the target conjugate nanomicelles.

Abstract
Model membranes formed from 1,2-dihexadecyl-, 1,2-dipalmitoyl-, 1,2-ditetradecyl- or 1,2-dimyristoyl-rac-glycero-3-phosphocholine, deuterium-labelled at choline groups, in an excess of water were compared using 2H-NMR spectroscopy. The dynamics and conformation of the labelled choline segments were estimated based on spin-lattice relaxation time and residual quadrupole splittings. The trimethylammonium group of dialkyl phosphatidylcholine was shown to be more distant from the bilayer surface as compared with that of the diacyl analogues.
