Изучено влияние температуры и ультразвука на интенсивность извлечения антоцианового пигмента и пектиновых веществ. Показано, что спектры, описывающие интенсивность извлечения антоцианового пигмента черной смородины, имеют два максимума поглощения при длинах волн 510 и 280 нм. Установлено соответствие максимумов поглощения антоцианового пигмента длине волны 510 нм и пектиновых веществ, ассоциированных с полифенолами, длине волны 280 нм.

Abstract:

The review summarizes studies on the detoxification effects of water-soluble humic substances (HS), which are products of the natural transformation of organic substances in soils and bottom sediments that serve as natural detoxifying agents in water solutions. The detoxifying effects of HS on microorganisms are quite complex: HS neutralize free pollutants (indirect bioeffects) and also stimulate the protective response of organisms (direct bioeffects). Prospects and potential problems of bioluminescent bacteria-based assay to monitor toxicity of solutions in the presence of HS are discussed.

Abstract:

These days, consumers are increasingly “nutritionally aware”. The trend of “clean label” is gaining momentum. Synthetic additives and preservatives, as well as natural ones, bearing the E symbol are more often perceived negatively. For this reason, substances of natural origin are sought tfor replacing them. Essential oils can be such substances. However, the wider use of essential oils in the food industry is severely limited. This is because these substances are highly sensitive to light, oxygen, and temperature. This creates problems with their processing and storage. In addition, they have

Acute myeloid leukemia (AML) remains an insidious neoplasm due to the percentage of patients who develop resistance to both classic chemotherapy and emerging drugs.

This mini-review aims to examine the advantages of using natural substances as P-gp inhibitors, focusing on four molecules: phytol, curcumin, lupeol, and heptacosane, and their mechanism of action in AML.

The goal was to determine the range of biologically active substances that can increase the productivity, organoleptic qualities of fish grown in recirculating aquaculture systems and optimize their living conditions. For this purpose, a complex of biologically active substances was tested, including probiotics, prebiotics, amino acids, and natural sorbents. It was introduced into feed and added to the water of fish tanks. Studies have shown that the developed comple

Abstract:

Extracellular enzymes secreted by Candida albicans are claimed to be virulence factors responsible for penetration of the yeast into host cells. Substances able to inhibit lipolytic and proteinase activities of the fungus might be of therapeutic use in some pathologic conditions caused by C. albicans. In the present work, we have tested the influence of the flavonoid compounds apigenin and kaempferol, the indole alkaloid ibogaine, and the protoberberine alkaloid berberine on the in vitro enzyme activity of C. albicans. The substances showed complex suppressive effects concerning the processes

Abstract The research on effectiveness of microbial consortia with growth-regulating and anti-pathogenic functions on the yield and quality of white cabbage had been carried out in the field conditions for 2 years. It was obtained that under N90P120K150, the use of the experimental biofungicide Tridem promoted an increase in nitrogen-fixing activity in the soil and a decrease in the infectious conditions in the rhizosphere under cabbage hybrids. The use of the experimental microbial complex BIS provided an increase in the mass of heads of cabbage, the accumulation of biologically active substa

Abstract:

Pharmaceutical and diagnostic substances like antibiotics, cytostatics and iodised X-ray contrast media (XRC) are well-known for not being metabolised and are excreted soon after application. As a result, these preparations are difficult to biodegrade and their adsorption behaviour is rather poor. Finally, the refractory properties of these substances are leading to an accumulation in the natural waterbody depending on the hydrological situation. The elimination of contrast media from urine and diluted urine solutions by ozonation was investigated using a bubble column reactor to remove and re

Cadmium diethyldithiocarbamate ([Cd(DDC)2]0) was used as a model lipophilic metal complex and Suwannee River Humic Acid (SRHA) was chosen as a representative aquatic humic acid (6.5 mg C L−1). Under the experimental conditions virtually all the Cd was expected to be present as the lipophilic complex ([Cd]T = 0.38 nM; [DDC] 1 μM; [Cd2+] <10−15 M; pH 7.0, 6.0, or 5.5). Uptake of [Cd(DDC)2]0

Environmental context. Lipophilic metal complexes, because they can readily cross biological membranes, are especially bioavailable. However, in natural waters these complexes do not necessarily exist in a free state, i.e. they may bind to the organic matter (humic substances) that is present in natural waters. It follows that the in situ bioavailability of lipophilic metal complexes will tend to be less than that measured in simple laboratory experiments. Abstract. The ability of dissolved humic substances (HS: fulvic and humic acids) to complex cationic metals is well known, but their intera
