The content of heavy metals, non-etherified and anionic forms of fatty acids, and also fatty acids of common lipids in honeycomb cells, obtained from hives placed in areas with high, medium and low levels of technogenic loading is investigated. The hives were located at the educational apiary of Lviv National University of Veterinary Medicine and Biotechnologies named after S.Z. Gzhytskyj (area with very heavy traffic and industrial activity) and in private beekeeping farms in the town Vynnyky and the village Chyzhyky, Pustomyty district, Lviv region (areas with lower intensity of traffic and industrial activity). Our research has shown that the newly-built honeycomb cells obtained from hives placed in the territory with medium and low levels of technogenic loading contain a lower quantity of such heavy metals as iron, zinc, cuprum, chromium, nickel, lead and cadmium. The total amount of non-etherified fatty acids with even and odd number of carbon atoms in the chain, monounsaturated fatty acids of n-7 and n-9 families and polyunsaturated fatty acids of n-3 and n-6 families was higher in these honeycombs. However, the total concentration of anionic forms of fatty acids with even and odd number of carbon atoms in the chain, monounsaturated fatty acids of n-7 and n-9 families and polyunsaturated fatty acids of n-3 and n-6 families was lower in these honeycombs. Due to the above-mentioned monounsaturated and polyunsaturated fatty acids the amount of fatty acids of common lipids rises. It leads to increase in the antibacterial and antifungal properties of honeycomb cells and reduction of fragility of their walls. The greatest changes in concentration of heavy metals, non-etherified and anionic form of fatty acids, and also fatty acids of common lipids occur in the newly built honeycomb cells in the territory with low technogenic loading on the environment.

Breastmilk is very much needed to meet the needs of babies in every way because it contains important nutrients, carbohydrates in the form of lactose, and fatty acids in the form of polyunsaturated fatty acids. Research on fatty acid content in breastmilk with a lactation period of 9 months is needed to provide information to the public related to fatty acid content of breastmilk during 9 months lactation. The study is to analyze fatty acid content in the form of saturated fatty acids or unsaturated fat contained in breast milk. Breastmilk taken in the study was as much as 50 ml in a 250 ml erlenmeyer solution. To the sample 50 ml of concentrated, HCL concentration was added as much as 5 m and then the solution was beat for 15 minutes and was exposed ultrasonic therapy for 1 hour. The solution was then extracted using n-hexane and aquabidest solution until the milk oil solution was separated. Milk oil was extracted by adding 50 ml of Na2SO4 1 m then deciphere was performed. The breastmilk milk extraction oil was weighed 0.1 gram in a Teflon-filled reaction tube. A 15% BF3 solution in methanol was added 0.5 ml and then was heated in an air bath with a temperature of 45 ° C for 30 minutes. After cooling, solution of 0.2 ml of n-hexane was added to form two layers. The upper layer which was fatty acid methyl ester was taken by using syringe and then was injected in GC-MS. In this study, the total saturated fatty acid was 42.54% and the total unsaturated fatty acid was 57.17%. Saturated fatty acids consisted of lauric, myristic, palmitate, and stearate. Omega-6 fatty acids and monounsaturated fatty acids consisted of omega-9 fatty acids. In Mother's Milk with 9 months lactation period there are various fatty acid content of both saturated fatty acids, monounsaturated fatty acids (omega-9) and polyunsaturated fatty acids (omega-6).

<p>Tabriz is a large and industrial city in the north west of Iran which suffers from severe air pollution due to being surrounded by mountains. Considering lack of official reports about the levels of heavy metals in Tabriz air, two zones of the city were selected for measurement of heavy metals in the air of this city. One of the two zones was located in a very heavy traffic zone of the city center, while the other was situated in a zone with relatively low levels of pollution. Three metals of lead, cadmium, and mercury were measured in these two zones. Among the three measured metals, lead with a concentration of 662 ng m<sup>-3</sup> had the highest concentration, followed by cadmium and mercury with concentrations of 92 and 8 ng m<sup>-3</sup> respectively. The concentrations of lead and cadmium in cold seasons were 30-50% greater than in warm seasons, whereas no significant correlation was observed between the concentration of mercury and the ambient temperature. No significant difference was observed between the concentrations of these metals in the two sampling sites; the levels of lead in winter in the city center were 20% greater than that in the countryside.</p>

The tissues of the head of honey bees which are kept in the areas with a medium and low level of technogenic burden demonstrate the decrease in the contents of iron, zinc, copper, chromium, nickel, lead and cadmium in comparison with the tissues of the head of honey bees grown in areas with a high level of technogenic burden. Due to the activity of saturated fatty acids with the even and odd number of carbon atoms in chain, monounsaturated fatty acids of n-7 and n-9 families and polyunsaturated fatty acids of n-3 and n-6 families, the contents of anionic fatty acids, which are inaccessible for the bee body, decreases in the tissues of the head of honey bees which are kept in the areas with a medium and low level of technogenic burden in comparison with the tissues of the head of honey bees grown in areas with a high level of technogenic burden. 3. Monounsaturated fatty acids of n-7 and n-9 families and polyunsaturated fatty acids of n-3 and n-6 families in the tissues of the head of honey bees lead to increase of the total number of easily accessible non-esterified fatty acids for the honey bees which are kept in the areas with a medium and low level of technogenic burden in comparison with the tissues of the head of honey bees grown in areas with a high level of technogenic burden. Furthermore, the intensity of transformations of the non-esterified form of linolenic acid in its more long-chain and more unsaturated derivatives rises in the head tissues of the former. This fact indicates that the reduction of technogenic impact on the area results in the increase of the activity of desaturase in the tissues of the head of honey bees. The contents of heavy metals, anionic and non-esterified fatty acids in the tissues of the head of honey bees which are kept in the areas with low level of technogenic burden undergoes the most significant changes.

Effect Of Age

The aim of the work was to evaluate the effect of age on the proportion of particular fatty acids in the whole bodies of pheasants fattened for up to 118 days of age. In the experiment, 232 chicks of common pheasants (Phasianus colchicus) were used. In the course of the experiment, the required number of pheasants was randomly selected for analysis at regular 10-day intervals. The age of pheasant chicks had a significant effect on the content of all fatty acids. Significant changes in the proportion of fatty acid groups were recorded mainly at 20, 40 and 60 days of age. By 20 days of age the proportion of monounsaturated fatty acids decreased considerably in relation to the increase in the content of polyunsaturated fatty acids, while the n6/n3 ratio decreased markedly. The content of monounsaturated fatty acids increased between day 20 and day 40, causing a simultaneous decrease in polyunsaturated fatty acids. From day 40, the monounsaturated fatty acid content increased gradually till the end of fattening, whereas the reverse trend was observed in the saturated fatty acid content in this period. As for polyunsaturated fatty acids, their presence increased from day 40 to day 60, followed by a gradual decrease till the end of fattening. The results of our work showed the different ability of pheasants to digest and utilize particular fatty acids with varying efficiency throughout their growth. The study brings new findings concerning changes in fatty acid composition of pheasants during fattening.

Abstract. To compare quality traits of longissimus lumborum muscle of three genotypes, 20 White Mangalica (WM), 20 crossbred Duroc  ×  White Mangalica (DWM) and 20 Large White (LW) pigs were allotted to the same indoor rearing and feeding conditions. Crossbred and LW pigs grew faster than WM pigs reaching 150 kg on average 168 and 288 days before WM, respectively. Meat from WM pigs had the highest intramuscular fat content and darkest and reddest colour; crosses were at an intermediate position, with significant differences among all genotypes. In addition, ultimate pH, water-holding capacity and iron content were significantly the highest in meat from WM pigs, compared to the other two genotypes. Crossing WM with Duroc had a significant effect on individual fatty acid content of meat. However, the sum of saturated, monounsaturated and polyunsaturated fatty acids remained unchanged. WM and DWM pigs had significantly more tender meat than LW pigs. Monounsaturated fatty acids (MUFAs) were most abundant, followed by saturated (SFAs) and polyunsaturated fatty acids (PUFAs) in meat from all animals. Meat from WM and DWM pigs had a significantly higher percentage of MUFAs and significantly lower percentage of SFAs than LW pigs.

AbstractThe strain SARS-CoV-2, newly emerged in late 2019, has been identified as the cause of COVID-19 and the pandemic declared by WHO in early 2020. Although lipids have been shown to possess antiviral efficacy, little is currently known about lipid compounds with anti-SARS-CoV-2 binding and entry properties. To address this issue, we screened, overall, 17 polyunsaturated fatty acids, monounsaturated fatty acids and saturated fatty acids, as wells as lipid-soluble vitamins. In performing target-based ligand screening utilizing the RBD-SARS-CoV-2 sequence, we observed that polyunsaturated fatty acids most effectively interfere with binding to hACE2, the receptor for SARS-CoV-2. Using a spike protein pseudo-virus, we also found that linolenic acid and eicosapentaenoic acid significantly block the entry of SARS-CoV-2. In addition, eicosapentaenoic acid showed higher efficacy than linolenic acid in reducing activity of TMPRSS2 and cathepsin L proteases, but neither of the fatty acids affected their expression at the protein level. Also, neither reduction of hACE2 activity nor binding to the hACE2 receptor upon treatment with these two fatty acids was observed. Although further in vivo experiments are warranted to validate the current findings, our study provides a new insight into the role of lipids as antiviral compounds against the SARS-CoV-2 strain.

The total lipid content and lipidic profile of seaweeds harvested in the North Coast and purchased in Portugal were determined in this paper. The amount of total lipids in the different species of seaweeds varied between 0.7 ± 0.1% (Chondrus crispus) and 3.8 ± 0.6% (Ulva spp.). Regarding the fatty acid content, polyunsaturated fatty acids (PUFA) ranged between 0–35%, with Ulva spp. presenting the highest amount; monounsaturated fatty acids (MUFA) varied between 19 and 67%; and saturated fatty acids (SFA) were predominant in C. crispus (45–78%) and Gracilaria spp. (36–79%). Concerning the nutritional indices, the atherogenicity index (AI) was between 0.4–3.2, the thrombogenicity index (TI) ranged from 0.04 to 1.95, except for Gracilaria spp., which had a TI of 7.6, and the hypocholesterolemic/hypercholesterolemic ratio (HH) values ranged between 0.88–4.21, except for Gracilaria spp., which exhibited values between 0.22–9.26. The n6/n3 ratio was below 1 for most of the species evaluated, except for Ascophyllum nodosum, which presented a higher value, although below 2. Considering the PUFA/SFA ratio, seaweeds presented values between 0.11–1.02. The polycyclic aromatic hydrocarbons (PAHs) and aliphatic hydrocarbons (AHCs) contamination of seaweeds under study was also quantified, the values found being much lower than the maximum levels recommended for foodstuff.

Abstract In this report, we have compared the fatty acid composition of the endemic Lake Baikal amphipods Ommatogammarus albinus (Dybowsky, 1874) and Parapallasea lagowskii (Dybowsky, 1874). Specimens were sampled using the deep-water manned submersible “Mir” at the oil-methane seeps of Cape Gorevoy Utes and at a hydrothermal vent in Frolikha Bay. High levels of monounsaturated fatty acids and relatively low levels of saturated and polyunsaturated fatty acids were detected in the studied amphipods, with oleic and palmitic acid representing the main fatty acid components. The habitat of the amphipods exerted a profound effect on their fatty acid profile: the amphipods of Gorevoy Utes contained higher levels of linolenic 18:3n3 and arachidonic 20:4n6 acids, while the amphipods of Frolikha Bay contained higher levels of eicosapentaenoic 20:5n3 and docosahexaenoic 22:6n3 acid. Based on these findings, we suggest that the amphipods’ diet in different areas of Lake Baikal determines their fatty acid composition.
