The alternations of sedimentogenic and asedimentogenic belts on the continental shelf and slope are distinctive features in the East Asia marginal *** sedimentogenesis characteristics areconditioned by the terrigenous material supply and their distribution patterns. Facial analysis of the marginal basins reveals a number of typical facial models which are comparablewith the geosynclinal and subplatform formations of the ancient basins. The paragenetical situation and simultaneous coexistence of these facial models in the modern margi-nal seas indicate that the ancient formation could be deposited in the same way,at the same time andeven in the same basin.

The capacities of phagocytes of subpopulation P1 (F) and morula cells (MC) of holothurian Eupentacta fraudatrix to modulate apoptosis of each other as well as cytokine-dependent mechanisms and hormonal regulation of these cells’s interaction were studied. The 18-h treatment of F with supernatants, obtained after centrifugation of MC preincubated for 3 h with phosphate buffered saline (PSB) at the temperature of 22℃?(SMC3) resulted in a significant growth of apoptosis level. A 30-min incubation of F with supernatants of MC, preincubated for 24 h (SMC24), on the contrary, reduced the apoptosis level and increased the level of interleukine-1α (IL-1α)-like substances, and 24-h incubation did not influence apoptosis and reduced level of IL-1α-like substances. Thus, proapoptotic effects of MC’s supernatants in F inversely depended on time of their preincubation with PSB and directly on time of incubation with F. Additionally, this effect was opposite to variations in the level of IL-1α-like substances. The level of apoptosis declined after 30 min of incubation but elevated after 24 h at the inverse treatment of MC with supernatant, obtained after preincubation of F during 24 h (SF24). The level of IL-1α-like substances dropped after 30 min and insignificantly decreased after 24 h. Hence, SF24 proapoptotic effect directly depended on time of incubation with MC and did not correspond to variations in the level of IL-1α-like substances. 100 μM dexamethasone stimulated apoptosis in F and MC in an inverse time-dependent manner during 24-h preincubation, and supernatants of cell suspensions obtained after such preincubations, stimulated apoptosis and reduced the IL-1α-like substances level in target cells at both types of interaction. IL-1α-like substances are?supposed to be mediators for MC’s effects in F, but not for F’s action on MC. In holothurians, steroid hormones apparently may participate in the regulation of the immune response and cell cooperation.

In view of increasing lead pollution(Pb^(2+)) of coastal waters, the compensatory abilities of holothurians need to be assessed. The goal of the work is to clarify the functional and phenotypical differences between two types of phagocytes(P1 and P2) in Eupentacta fraudatrix exposed to Pb(NO_3)_2. It has been shown that 2 mg L^(-1) lead exposure for 48 h increases the number of P2 phagocytes as compared to P1 cells, does not significantly affect cell viability in both P1 and P2 phagocyte fractions, and significantly enhances chromatin condensation in P2 but not in P1 phagocytes. A lead concentration of 4 mg L^(-1) increases the number of P1 phagocytes compared to that of P2 type, and does not change cell viability and chromatin condensation in P1 phagocytes. In the P2 type, it decreases cell viability and does not influence the level of apoptosis. The protection against lead-induced apoptosis is apparently mediated by the activities of antioxidant enzymes, especially glutathione S-transferase. The differences in labeling cell surface receptors of P1 and P2 phagocytes by plant lectins also indicate the specific phenotypic properties of these cells. The results clarify the potential and GSH-dependent mechanisms of immune adaptation in holothurians that have been shortly exposed to lead at concentrations close to the maximum environmentally relevant level in coastal waters. Additionally, P1 and P2 phagocytes are first shown to have different functions and phenotypes during the response to lead, which indicates the complexity of the phagocytic system in holothurians and contributes to understanding the immunity evolution.

The practical significance of the established generalized differential formula-tion of the first law of thermodynamics (formulated for the rotational coor-dinate system) is evaluated (for the first time and for the mesoscale oceanic eddies) by deriving the general (viscous-compressible-thermal) and partial (incompressible, viscous-thermal) local conditions of the tidal maintenance of the quasi-stationary energy and dissipative turbulent structure of the mesoscale eddy located inside of the individual fluid region of the ther-mally heterogeneous viscous (compressible and incompressible, respective-ly) heat-conducting stratified fluid over the two-dimensional bottom topog-raphy characterized by the horizontal coordinate x along a horizon-tal axis X. Based on the derived partial (incompressible) local condition (of the tidal maintenance of the quasi-stationary energy and viscous-thermal dis-sipative turbulent structure of the mesoscale eddy) and using the calculated vertical distributions of the mean viscous dissipation rate per unit mass and the mean thermal dissipation rate per unit mass in four regions near the observed mesoscale (periodically topographically trapped by nearly two-dimensional bottom topography h(x) eddy located near the northern region of the Yamato Rise in the Japan Sea, the combined analysis of the energy structure of the eddy and the viscous-thermal dissipative structure of turbulence is presented. The convincing evidence is presented of the tidal mechanism of maintenance of the eddy energy and viscous-thermal dissipa-tive structure of turbulence (produced by the breaking internal gravity waves generated by the eddy) in three regions near the Yamato Rise subjected to the observed mesoscale eddy near the northern region of the Yamato Rise of the Japan Sea.
