Distribution of Sprattus sprattus phalericus (Risso, 1827) and zooplankton near the Black Sea redoxcline.

Understanding what environmental drivers influence marine predator-prey relationships can be key to managing and protecting ecosystems, especially in the face of future climate change risks. This is especially important in environments such as the Black Sea, where strong biogeochemical gradients can drive marine habitat partitioning and ecological interactions. We used underwater video recordings in the north-eastern Black Sea in November 2013 to observe the distribution and behaviour of the Black Sea sprat (Sprattus sprattus phalericus, Risso 1827) and its zooplankton prey.

[Standardization of di-chlor-di-para-xylilene, di-bromine-di-para-xylilene and di-para-xylilene].

Studied were the new components of dielectric coatings: di-para-xylilene, di-bromine-di-para-xylilene, dichlor-di-para-xylilene, which manifested themselves as low-toxicity compounds free from irritating, sensitizing and fibrogenous effects. The acute action thresholds for aerosols of the paraxylilenes were established at 10 mg/m3 (with regard to general and embryotoxicity), at 5 mg/m3 for the maximal inactive concentrations.

[Characteristics of the response of animals of different typological groups to the action of electromagnetic irradiation in the high and superhigh frequency ranges].

Peculiarities in the response of male rats of various typological (e.g. high- and low-entropy) groups to the effect of electromagnetic radiation of high and superhigh frequencies have been investigated.

[Effect of discontinuous short-wave electromagnetic field irradiation on the state of the endocrine glands].

A study was made of the effect of interrupted EMF SW of 500 and 250 V/m on endocrine glands of male rats. The following changes were noted: activation of neurosecretion in hypothalamus, inhibition of adrenocorticotropic and gonadotropic functions of hypophysis and adrenal cortex, degenerative and dystrophic changes in testes. The observed disorders were aggravated as the intensity of the field and duration of exposure increased.

[Pathogenetic therapy of cobalt-induced cardiomyopathies].

The pathogenesis of damage to the heart muscle caused by exposure to the effect of cobalt compounds is demonstrated. Agents with various mechanisms of action were tested in the experiment. The most effective pharmacological agents (beta-adrenergic blocking agents, anabolic steroids) are recommended for testing in the clinic.
