Cosmeceuticals are preparations that are described in numerous scientific and popular science works as combining the features of a drug and a cosmetic. They are cosmetics, but unlike the traditional ones, they contain a high concentration of active ingredients, usually plant-based, obtained with the use of modern pharmacy, biotechnology and molecular biology techniques. The aim of the study was to present, based on scientific literature, cosmeceuticals as multi-ingredient products and their impact on human skin. Active substances contained in cosmeceuticals cause their more intense action than traditional cosmetics. Therefore, they should be used based on the professional advice of a cosmetologist, pharmacist or doctor.

An interest in plants of Amelanchier genus is stimulated by the necessity of search for plant sources rich in biologically active substances and possessing the ability to influence different physiological processes in a human organism. The article gives information about places of growth of different species of Amelanchier (Amelanchier Medic) and about the fact that its fruits contain high concentration of free sugars, relatively low level of organic acids, sufficient amounts of various vitamins and provitamins and a complex of mineral substances. Nutritive and biological value of Amelanchier fruits in complex may produce a beneficial effect on different biochemical and physiological processes of normal vital activity of a human organism. The data are given about a positive influence of enteral introduction of polysaccharides isolated from Amelanchier fruits, on different physiological processes that enhance adaptational reserves of an organism of experimental animals. In particular, it was shown that watersoluble polysaccharide complex (WSPC) of Amelanchier fruits activates erythropoiesis increasing the amount of erythrocytes and hemoglobin in blood of experimental animals and raises concentration of iron. WSPC improves physical working capacity and increases the body mass of experimental animals. Addition of watersoluble polysaccharide complex of Amelanchier fruits to blood of a healthy donor increases thermal, osmotic and peroxide resistance of erythrocyte membranes thus protecting cells against damage under action of adverse factors in the experiment. Fruits of plants of Amelanchier genus may be recommended to be used as a food additive or a product in dietary and prophylactic therapy.

Abstract Homogenate is a source of a huge amount of biologically active substances. However, it is produced in a small number of apiaries, since the cultivation of drone brood negatively affects honey productivity. This paper aimed to study the influence of rearing drone larvae on the power and honey productivity of bee colonies since these issues are not widely addressed in scientific literature. Three groups (control, experimental 1, and experimental 2) of 10 bee colonies were formed by the method of pairs-analogs. One brood frame was placed in the bee colonies of the first experimental group, and two frames were placed in the colonies of the second experimental group. The brood frames were placed on June 12, the clipping was done on June 30, and the honey was collected on July 12. The power of colonies was taken into account after wintering (in March) and at the end of the pre-wintering season (in November). As a result of the research, it was revealed that the homogenate of drone brood can be obtained in apiaries of the Primorsky Krai. It was proved that when adding one brood frame to obtain a homogenate, the main production of the apiary - honey, does not decrease, and a negative effect on honey productivity was observed when adding the second brood frame.

This article deals with the phytochemical, morphological and anatomical investigation of ethanol-based extracts derived from the leaves and stems of the Aegopodium alpestre. The vegetative organs of A. alpestre were conserved according to Strasburger-Fleµming method using a 1:1:1 mixture of alcohol-glycerin-water. A total of 1200 ethanol-based extracts (2 from leaves and 2 from stem tissues per plant) were prepared using the Soxhlet extractor. All extracts were used to identify organic and inorganic compounds in the leaves and stems of the studied plant. Contents of biologically active substances, microelements, vitamins and amino acids were determined. This article is the first paper to display very high concentration and diversity of vitamins (6 types), micronutrients (5 types), and aminoacids (13 types) in the leaves and steams of A. alpestre. Findings conclude that identification of biologically active substances in the above the ground vegetative organs of A. alpestre may be a common practice in the future. Considering the study results, A. alpestre may be used as a medicinal plant on a large scale. For this, the cultivation practice needs to be scaled up.

Face aging is a challenging work in image processing and computer animation field. In this paper, a novel local image Laplacian differential method is proposed to learn this complex face transformation. Firstly, together with the facial feature points correspondence, we extract the aging facial details from example face and apply to the target one by a global and a local Laplacian skin aging model respectively, and the latter makes the results more realistic in our experiment. Then, the skin color and hair style adjustments are carried out to simulate the aging process completely, making the results look more competitive and natural. Our experiment shows that our method is robust and appreciable.
