Adjuvants have been used for decades to enhance the immune response to vaccines, in particular for the subunit-based adjuvants. Physicochemical properties of the adjuvant-protein antigen complexes, such as size, morphology, protein structure and binding, influence the overall efficacy and safety of the vaccine. Here we show how to perform an accurate physicochemical characterization of the nanoaluminum–ovalbumin complex. Using a combination of existing techniques, we developed a multi-staged characterization strategy based on measurements of increased complexity. This characterization cascade has the advantage of being very flexible and easily adaptable to any adjuvant-protein antigen combinations. It will contribute to control the quality of antigen–adjuvant complexes and immunological outcomes, ultimately leading to improved vaccines.

Pre-harvest sprouting (PHS) severely reduces rice grain yield, significantly affects grain quality, and leads to substantial economic loss. In this study, we aimed to characterize the physicochemical properties and processing quality of the Garumi 2 flour rice variety under PHS conditions and compare them with those of the Seolgaeng, Hangaru, Shingil, and Ilpum rice varieties and the Keumkang wheat variety. Analysis of the molecular structure of starch revealed uniform starch granules, increased proportions of short-chain amylopectin in DP 6–12 (51.0–55.3%), and enhanced crystallinity (30.7–35.7%) in rice varieties for flour compared with the Ilpum cooking rice variety. PHS significantly altered the starch structure and gelatinization properties of Garumi 2. It also caused surface pitting and roughness in Garumi 2 starch granules and decreased their crystallinity. Collectively, the findings of this study provide important novel insights into the effects of PHS on the physicochemical properties of Garumi 2 floury rice for flour.

In this study, two sites from tea and apple growing sites were collected from Pyay village and Nine Mile village, Mindat district, Chin state of West Myanmar under a humid subtropical climate. The results of physicochemical properties of observed soils were neutral pH, favorable moisture, silty clay loam texture, very high content of organic carbon, organic matter and total nitrogen. However, the tea growing soil was very poor in phosphorus and potassium content. Moreover, both soils lack of available potassium. The content of heavy metals in both soils was not varied from each other and followed the order: Fe (iron) > Cu (copper) >Zn (zinc) > Pb (lead) > Cr (chromium) and was below the maximum allowed concentrations (MAC). Therefore, the studied soils are generally favorable for cultivation under the condition of application of phosphorus and potassium fertilizers. However, due to the regular application of fertilizers and pesticides, it is necessary to monitor these soils for PTE levels. Further research is recommended, which must include analyses of the physicochemical properties of soils to a two depths of 0-30 and 30-60 cm, especially for the area where fruit plants are grown. In addition, higher density of soil samples and sub-samples are necessary to produce a reliable dataset that will allow proper statistical analysis.

В условиях двухлетнего полевого опыта на растениях льна-долгунца исследовано влияние внекорневой подкормки боросодежащими хелатными комплексонами на продуктивность и качество льнопродукции. Изучено действие борат-иминодисукцината (В-ИДЯК) и борат-этилендиаминдисукцината (В-ЭДДЯК) в сравнении с борной кислотой и борат-этилендиаминтетраацетатом (В-ЭДТУК). Исследования выполнили в 2019–2020 гг. в однофакторном полевом опыте. Установлено, что наиболее эффективное и экологически безопасное влияние оказывает внекорневая подкормка посевов льна-долгунца хелатным комплексом В-ЭДДЯК. При внекорневой подкормке часть препарата, попадая в почву, мобилизует также другие микроэлементы, тем самым оказывая стимулирующее действие на растения. Полученные результаты показали, что внекорневая подкормка боросодержащими соединениями существенно повлияла на накопление биомассы льна-долгунца. Выявлена положительная динамика влияния боросодержащих комплексов на прохождение фенологических фаз во второй половине вегетации. Внекорневая подкормка растений ускорила цветение льна, которое наступало раньше на 2–3 дня по сравнению с контролем. Применение подкормки хелатными боросодержащими комплексонами способствует росту урожайности растений, повышению качества продукции, в части улучшения физико-химических свойств льноволокна. Прибавка урожая к контролю составила: по льносоломе – 8,3–15,7% (3,2–6 ц/га), семенам – 38,4–56% (1,2–1,9 ц/га). Техническая длина соломы была выше у всех вариантов опыта на 8,5–10,4% по сравнению с контролем. При этом увеличивались: выход луба, прочность, пригодность и номер льносоломы. Увеличение содержания луба составило от 1,6 до 4,5%. Under the conditions of two-year field test, the effects of foliage application with boron-containing chelate complexones on the productivity and quality of flax products were investigated on long-stalked flax plants. The effect of borate-iminodisuccinate (B-IDSA) and borate-ethylene diamin-disuccinate (B-EDDSA) in comparison with boric acid and borate-ethylene diamintetraacetate (B-EDTAA) was studied. The researches were conducted in 2019–2020 in a single-factor field test. It has been found that the most effective and environmentally safe influence is exerted by foliage application of long-stalked flax sowings with the chelate complex B-EDDSA. In foliage application part of the preparation falling into the soil also mobilizes other trace elements, thereby exerting a stimulating effect on plants. The obtained results showed that foliage application with boron-containing compounds had a significant impact on the accumulation of long-stalked flax biomass. Positive dynamics of boron-containing complexes influence on phenological phases passage in the second half of growing season has been revealed. Foliage application of plants accelerated flax flowering, which occurred earlier by 2–3 days compared to control. The use of top-dressing with chelated boron-containing complexones contributes to the growth of plant yields, an increase in the quality of products, in terms of improving the physicochemical properties of flax fiber. The increase in the yield to control was: according to linen straw – 8.3–15.7% (3.2–6 c/ha), seeds – 38.4–56% (1.2–1.9 c/ha). The technical length of the straw was 8.5–10.4% higher in all experience variants compared to the control. At the same time the output of the bast, the strength, suitability and number of the linen straw have been increased. The increase in bast content ranged from 1.6 to 4.5%.

The study was conducted to investigate the possibility of enhancing the quality of cultured snakehead fish (Channastriata) protein, especially used in the processing of sausage products, by treatment with protease from its viscera. The change in physicochemical properties (expressed by water holding capacity, emulsifying capacity of protein, texture characteristics and whiteness index) of snakehead fish paste related to various protease activity (0, 3, 6, 9, 12, 15 U/L) and washing time (20, 30 and 40 min) were determined. In addition, protease treatment conditions were fixed at ambient temperature (30 ± 2 °C) and the ratio of minced fish and protease solution was 1:1(w/v). The results showed that physicochemical properties, gel quality and sensory properties of sausage significantly improved from soaked minced fish in protease solution at 9 U/L for 30 minutes.
