Harsh or extreme environmental conditions largely determine the vegetative and reproductive development of plants. In the case of cultivated plants, their growth and yield are clearly diminished if ...they are exposed to severe conditions such as drought, waterlogging, extreme heat or cold, UV radiation, or toxic substances in the soil such as salts, heavy metals and pesticides. Melatonin has been studied for decades as a molecule capable of reducing the negative effects of abiotic stressors by increasing tolerance to these adverse growth conditions. This work presents a review of the most outstanding studies with various plant species in each of the above-mentioned stress situations, including proteomic and post-translational studies. Melatonin mediates plant responses to abiotic stress, generally inducing an antioxidative response, and also regulating a complex gene response adapted to individual stressors. Plants are able to increase their endogenous melatonin levels through the application of exogenous melatonin or through the inductive mechanism of endogenous melatonin biosynthesis. In such ways, plants are able to cope with the stressful situation at hand, accommodating their metabolism, morphology and physiology in order to increase overall survival and induce greater tolerance to stress. The agronomic implications of the use of melatonin are discussed.
The robust safety and efficacy profile associated with the use of biodegradable fillers such as poly-L-lactic acid (PLLA) for facial rejuvenation has resulted in a growing interest in off-label use ...for various aesthetic applications, including gluteal augmentation. The authors describe a novel targeted and individualized technique of PLLA injection into the buttock region.
The technique involves clinical and anatomical evaluations of the gluteal region, and there are three distinct approaches for injecting PLLA in the gluteal region based on the most important factor to be improved: (1) skin quality, (2) contour and lifting, or (3) projection and volume.
This novel technique is associated with favorable patient outcomes in terms of improvements across all key areas of gluteal augmentation; improvement in skin quality and laxity, contour improvement and lifting, and gluteal volume and projection. Since its initiation, this technique has been found to be both cost-effective and clinically efficacious, with demonstratable benefits achieved with a lower volume of PLLA compared to other PLLA injection techniques.
Assessment of patient outcomes with this technique have, to date, been subjective clinical observations, which does not include quantitative outcomes such as patient satisfaction data or safety outcomes.
We describe an optimized and individualized approach for injecting the collagen biostimulator PLLA in the gluteal region according to the needs of each patient.
Long-term unsystematic use of near-settlement pastures in the desert zone of South Kazakhstan had a negative impact on the physic-chemical parameters of Calcisol. Excessive grazing leads to trampling ...of soil and reduction of soil fertility. The aim of the study was to develop a technology to improve the productivity of degraded near-settlement pastures. The tasks of the research are to determine the effect application of environmental safe biostimulator and biofertilizer on microbial communities, the content of carbon and phosphorus in the soil, the effectiveness of biostimulator application on degraded pastures in order to increase green mass. For this purpose, geobotanical, bacteriological and helminthological methods of analysis were used. The result of the used proposed technology is the activation of soil microorganisms, which leads to the prevention of degradation of arid pastures. The results of our research contribute to the introduction of a better technology to increase the productivity of arid near-settlement pastures. Statistical analysis of the experiments showed that all manipulations on soil microorganisms increase the number and green mass of arid plants.
By creating highly productive phytobiomes, selection of new types of biostimulants on the basis of organic substances and microorganism has a decisive role. It could be done by taking into account ...natural and climatic peculiarities of the region. The article described the importance of sugar sorghum and substantiates the introduction of an adaptive variety to increase the productivity of fodder sorghum and the best option of using growth biostimulants. The results of evaluating the effectiveness of growth biostimulants under laboratory conditions on the main nutritional valuable traits were presented. The treatment of optimal parameters of sugar sorghum seeds with biostimulants in the Research laboratory "Industrial biotechnology" of M. Auezov South Kazakhstan University was determined. It was shown that the "Azotofertil" biostimulator has a high efficiency in pre-sowing seed treatment. For comparative evaluation of potentialities of new biostimulant, MERS biostimulant adapted to climatic conditions was chosen. According to research results, both biostimulants showed high efficiency for seed pre-sowing treatment. The best concentration for treatment of planting material was established. Energy of germination, swelling and the number of germination of seeds of sugar sorghum variety Kazakhstan-16 were determined. In evaluating the activity of biostimulants for efficiency, the dynamics of their friendly germination was traced. At 4% concentration and temperature above 14°C, the advantage of "Azotofertil" biostimulator based on Azotobacter chroococcum strain was proven. Seeds of sugar sorghum variety Kazakhstan-16 showed the best results with 96±3% germination.

Safflower oil is a rich source of omega-3 fatty acids that is important for health. Drought stress can severely decrease the productivity and oil quality of safflower. Thus, in order to study the ...effect of hydropriming and melatonin-seed-priming on fatty acid composition and yield of Safflower under water deficit conditions a field experiment was carried out as split-factorial in a randomized complete block design with four replicates during 2017 and 2018 growing seasons. The oil concentration of the safflower seeds was determined by soxhlet extraction method. Fatty acids of safflower’s oilseed were transformed to their methyl esters (FAME), and a gas chromatograph equipped with a flame ionization detector (FID) was used for determination of fatty acids. The results indicated that melatonin-seed priming increased grain yield, HI and oil yield of safflower under drought condition. Drought stress led to a significant decrease in oil yield, and recently harvested seeds had higher oil yield across both years. The highest amount of oil yield was obtained by hydropriming on seeds which had been stored for 8 years, and recently harvested seeds with 576.50 and 645.57 kg.ha
−1
, respectively under no-stress condition. Melatonin-seed-priming improved the oil quality of safflower under drought with an increase of unsaturated fatty acids of safflower especially omega 6 and omega 3. Melatonin-seed priming increased the amount of ∑PUFA, ∑UFA/∑SFA, P/S and DBI across both years in comparison with unprimed seeds. Seed priming improved the quality of oil and productivity in both recently harvested and stored seeds. It can be concluded that melatonin-seed priming improved the productivity, oil content and composition especially in stored seeds and under drought stress.

Introduction
Clinical data on body contouring with injectable poly‐L‐lactic acid are sparsely reported in published literature. This study describes the lead author's clinical experience using ...injectable poly‐L‐lactic acid for body contouring in various anatomic locations.
Methods
Twenty consecutive patients undergoing body contouring treatments with poly‐L‐lactic acid were prospectively followed. All treatments were performed at a single clinic between February 2017 and February 2019. Treatment details such as reconstitution, injection volume and dosage were documented. Treatment response was assessed independently by patients and the treating physician. Adverse events were recorded.
Results
Twenty patients (85% women) received injectable poly‐L‐lactic acid for body contouring treatments such as buttocks volumization, cellulite and skin quality treatment. In most patients (65%), poly‐L‐lactic acid was administered to correct postsurgical soft tissue deformities. Overall, patients had a mean of 5.1 treatment sessions in a mean of 1.4 anatomic locations. The most commonly treated anatomic locations were buttocks (58% of treatment sessions), thighs (20%) and abdomen (9%). Dosage and injection volume varied between patients depending on anatomic location and desired outcome. Most treatment sessions (86%) resulted in improvement of the treated area. Adverse events included bruising, oedema, numbness and tenderness. Nodule formation was recorded for one patient (5%).
Conclusion
According to the lead author's clinical experience, poly‐L‐lactic acid injection is well tolerated and can achieve good aesthetic outcomes when used for body contouring in appropriate patients. Preliminary data suggest that poly‐L‐lactic acid injection may be a viable nonsurgical technique for correcting postsurgical soft tissue deformities.
