In the given article the existing technologies of hulled oats grain processing into groats products were analyzed. The possibilities of using new breeding varieties of oats to improve existing technologies were analyzed. Advantages using naked oat varieties for the production of groats and flakes were considered. Results of research influence intensity of pearling and water heat treatment on yield of pearled groats and its quality indicators were shown. The high efficiency of use naked oats for the production of pearled groats with regulated quality indicators was determined. It was found that the technologically expedient moisture content of naked oats before pearling is 12-12.5 %. In the pearling the grain with this humidity depending on the duration of pearling yield of groat estimated to range between 78 94 %. Use as raw materials naked oats increase yield of pearled groats at 1.4-1.6 times in compared to processing of conventional varieties. Modes of preparation of pearled groats for flaking was investigated, feature their influence on the yield and qualities of flaked groats were determined. Analyses of the physical properties of the obtained flaked products were conducted. It was found that the technologically expedient moisture content of pearled naked oats groats before steaming is 17-17.5 %. After steaming groats with this moisture yield of flaked groat estimated to range between 84,3 93,6 %. The main stages of processing naked oats into groats products were determined. The technological scheme of processing naked oats for producing groats and flakes were developed. The technological scheme of processing hull-less barley and naked oats for producing groats, flakes, mixtures of groats and flakes were developed. Technology includes grain cleaning stage, grain water heat treatment, pearling, sorting of pearling products, pearled groat water heat treatment, mixing, flaking, drying, and control of end products.

Among the many types of grinding machines used in enterprises of grain processing, food and other industries, an important place belongs to hammer crushers. This is explained by the possibility of their use for grinding materials of various origins (plant, animal, mineral, as well as various wastes of food production), various particle size distribution (lumpy, briquetted, granular, fibrous), having different strength properties (hard, medium hard, soft, brittle, viscous), capable of being crushed once or requiring double sequential crushing. In addition, hammer crushers are characterized by relative simplicity of design, and most importantly - they destroy materials in the most rational way - by impact loading as a result of two successive strokes: a hammer on a particle and particles on the surface of the deck. The execution of these attacks at right angles creates the conditions for the intensification of the destruction process. However, the wear of the hammers leads to a rounding of their impact faces, which makes the angles of attack in the active zone of the hammers significantly different from the direct one. Under the influence of shock-frictional loads, their working surfaces quickly wear out, which leads to a decrease in productivity and crushing efficiency, to an increase in energy consumption, a disturbance in the balance of hammer rotors, an increase in the vibroacoustic activity of crushers, and other negative consequences The invention of the “Hammer of the crusher” provides for the use of ring-shaped multi-toothed hammers, the durability of which, when using traditional materials and conventional heat treatment, is increased by 4...5 times, eliminates the need for periodic rearrangement of hammers, stabilizes the operation of crushers. The possibility of self-sharpening ring-shaped multi-toothed hammers after reversing the hammer rotor simplifies the maintenance of crushers, eliminates personnel errors when replacing worn hammers. If multi-toothed hammers are subjected to liquid non-electrolysis boration and heat treatment using an optical quantum generator, then their durability can increase by more than ten times.

Interleukin-6 (IL-6) has been identified as a 26-kD secreted protein that stimulates B cells to produce antibodies. Later, IL-6 was revealed to have various functions that overlap with other IL-6 family cytokines and use the common IL-6 signal transducer gp130. IL-6 stimulates cells through multiple pathways, using both membrane and soluble IL-6 receptors. As indicated by the expanding market for IL-6 inhibitors, it has become a primary therapeutic target among IL-6 family cytokines. Here, we revisit the discovery of IL-6; discuss insights regarding the roles of this family of cytokines; and highlight recent advances in our understanding of regulation of IL-6 expression.

Gold-based metallodrugs have been used for a wide variety of medical–related applications. Although none of them have reached clinical trials, many compounds show potential for a plethora of possible applications. Platinum compounds, on the other hand, are the leading class of metallodrugs used for the treatment of cancer, with successful representatives worldwide, such as cisplatin, carboplatin and oxaliplatin. In this minireview, we will briefly present the development of metallodrugs based on such metals throughout the year of 2017.
