The environmental health citizen interview tool: towards an inclusive qualitative environmental wellbeing approach in support of planetary health.

Background: Nature-based Solutions (NbS) are vital for addressing climate change and biodiversity loss, yet their benefits are often unequally distributed. This study introduces the Environmental Health Citizen Interview Tool, aiming to inclusively capture diverse perspectives on environmental wellbeing using qualitative research methods. The principles of epistemic justice and planetary health are central to its development.

[PHOSPHOLIPIDS, FATTY ACIDS AND HEMOGLOBIN OF ERYTHROCYTES IN RAT BLOOD UNDER STRESS CONDITIONS (SWIMMING AT A LOW TEMPERATURE)].

The phospholipid and fatty acid content of erythrocytes in rat blood was studied after exposure to stress - swimming up to drowning. This stress was found to increase the content of phospholipids cha- racteristic for the membrane outer layer (phosphatidilcholine by 13 % and sphingomyelin by 23 %). At the same time a decrease in the content of acid phospholipids belonging to membrane inner layer was ob- served (phosphatidylethanolamine by 16 %, phosphatidyl serine by 14 % and monophosphoinositide by 23 %).

[PHOSPHOLIPIDS AND FATTY ACIDS IN ERYTHROCYTES OF THE LAMPREY LAMPETRA FLUVIATILIS DURING AUTUMN PRESPAWNING PERIOD AND THE ABSORPTION SPECTRUM OF THEIR LIPID EXTRACT].

The content of some classes of phospholipids and their fatty acid composition in erythrocytes of the lamprey Lampetrafluviatilis during the autumn period of its prespawning migration are investigated. It is found that the phospholipid spectrum of erythrocytes of the lamprey, the oldest representative of vertebrates, is similar to that of many mammals. A four-fold prevalence of phosphatidilcholine content over sphingomyelin content as well as prevalence of (ω3-acids over ω6-acids indicates the <> of lamprey's erythrocyte membranes - an important indicator of deformational ability of lamprey's erythrocytes.

[Fatty acid composition of phospholipids of erythrocytes of lamprey, frog, rat, and absorption spectra of their lipid extracts].

The work deals with study of content and fatty acid composition of phospholipids as well as of absorption spectra of lipid extracts of blood erythrocytes poikilothermal and homoiothermal animals of different evolutionary levels. Objects of study were poikilothermal lamprey (Lampetra fluviatilis) consuming oxygen from water and the common frog (Rana temporatia) consuming it both from water and from air. Homoiothermal animals were white rats (Rattus rattus) inhabiting in the air medium.

[Effect of stress actions on some hematologic and biochemical parameters of rat blood and on energetic intermolecular interactions in lipid extract under effect of light radiation].

Comparative study has been carried of effect of the three-day long starvation, running, and their combination on morphological parameters of rat blood, lipid metabolism, and activity of blood Na,K-ATPase. Different effect has been shown of these stress factors on the blood erythrocyte composition. Starvation is accompanied by the most pronounced release of stored erythrocyte into blood, which results in a significant decrease both of the total amount of reticulocytes and the complete absence of reticulocytes of the I stage of maturity (the youngest).

[Bounds of change in unsaturation index of fatty acid composition of phospholipids at adaptation of molluscs to biogenic and abiogenic factors of external medium].

Comparative study of fatty acid composition of total phospholipids, as well as of phosphatidylcholine and phosphatidylethanolamine from hepatopancreas and leg muscle was performed on several representatives of gasteropods (Gastropoda) molluscs and bivalve (Bivalvia) mussel (Mytilus edulus). The objects of our study were marine litorins (Littorina saxsatilis) adapted to different temperature conditions of White Sea and Barents Sea, freshwater lymnaea (Lymnaea stagnalis) infested by Trematoda and mussels from White Sea and Black Sea. It was shown that depending on the existence conditions of studied tissue or lipid, the maximal change is observed in the percentage of saturated acids (4-83 %), the percentage of unsaturated acids was less expressed (1-14 %) and the changes in unsaturation index (UI) did not exceed 20 % on average.

[Effect of total hypothermia on the fatty acid composition of blood phospholipids of rats and sousliks and light irradiation on chemical processes in lipid extract].

Effect of hypothermia on the fatty acid composition of rat and souslik blood phospholipids is studied. Different reaction of these animals to cooling is revealed: in rats no changes were observed in the fatty acid composition of blood phospholipids, whereas in the hibernating there were significant changes in the content of individual fatty acids (FA). The content of monoenic acids in sousliks decreased almost by 50%, while the content of saturated acid (C18) and of polyenic acids C18 : 2omega6 and C20 : 4omega6 rose significantly.

[Fatty acids of phospholipids of brain cell nuclei in rat ontogenesis].

Experiments were carried out on the 19-day old rat embryos, the 5- and 45-day old rat pups, and the 1.4-1.5-year old rats.

[Significance of electron interactions of fatty acids of phospholipid molecules in the organism adaptation to habitation temperature].

Data in the fatty acid composition of muscle tissue phospholipids of some representatives of gastropod molluscs (Gastropoda) have been presented for the first time. In the lake phytophagues Lymnaea stagnalis and Lymnaea ovata the long-chained C22-acid was not detected, whereas in the predator common whelk Buccinum undatum, C22:6omega3 was present. Comparison of absorption spectra (240-720 nm) of lipid extracts of the studied invertebrates and of rat has been performed.

[About effect of habitat and motor activity of molluscs on fatty acid composition of triglycerides and phospholipids].

A comparative analysis of fatty acids (FA) in neutral and phospholipids of digestive gland and pedal muscle has been performed in molluscs from various ecological groups differing by belonging to sea or fresh water, trophic types or the associated motor activity. In freshwater pulmonary gastropods Lymnaea stagnalis and Limnaea ovalis and marine prosobranchial molluscs Buccinum undatum and Littorina littorea the total content of omega3-acids in phospholipids of the studied tissues differed more than twice, predominantly due to the combined effect of temperature and salinity of the habitat. The lower viscosity of cell membranes in marine species (omega3/omega6 < 1) is determined to the greatest degree by the presence of eicosapentaenoic acid that accounts for 22-25 % of the FA sum in marine species.

[About paired correlation of pi-electrons tissue lipid extracts of animals of different evolutionary levels].

With aid of optical methods, the presence of the paired correlations of pi-electrons has been revealed in phospholipids as well as in triacylglyceride molecules. Used for analysis were lipid extracts of individual representatives of animals of various evolutionary levels--cartilaginous and bony fish and mammals differing by the content of unsaturated fatty acids in lipids. It has been established that the necessary condition for formation of electron pairs is interaction of lipid molecules with each other.

[Changes produced by trematode larvae in the phospholipid fatty acid composition of digestive gland of the mollusc Littorina saxatilis].

Lipids of the digestive gland of the mollusc Littorina saxatilis from the White and Barents Seas were studied. Changes of its biochemical composition are discussed in the connection with different temperature of the habitat and with infestation with trematode larvae. Comparative analysis of the fatty acid (FA) composition of each of phospholipids in intact molluscs has revealed essential differences.

Physiology and lipid metabolism of Littorina saxatilis infected with trematodes.

Physiological and biochemical alterations in Littorina saxatilis infected with larval trematodes were investigated and compared with the metabolism of non-parasitized snails. Oxygen consumption rates of infected snails differed from those of non-infected controls in medium sized individuals (30 to 130 mg) but not in very large infected individuals (> 200 mg). Small snails (0.

[Combined effect of environmental temperature and trematodes on fatty acids composition of lipids of Littorina saxatilis (Olivi 1792) (Gastropoda, Prosobranchia)].

An effect of environmental temperatures and invasion by helminthes larvae on fatty acids composition of digestive gland lipids of marine littoral gastropod Littorina saxatilis from White Sea and Barents Sea was investigated. We have compared gastropods from boreal and subarctic populations. It was found that gastropods from waters of lower temperature have increased omega3/omega6 fatty acids ratio.

[Lipids of the bone tissue in bodies of thoracic vertebrae in scoliosis in rabbits].

The content of total lipids, triglycerides, cholesterol and phospholipids in the bone tissue of the bodies of the thoracic vertebrae was investigated in 4.5-, 7- and 12 month old rabbity. The development of scoliosis in two month old animals was induced by the one-sided blockade of the afferent links of the innervation in thoracic region at the extent of four segments (TH6-9).

Phospholipids and their fatty acids in mitochondria, synaptosomes and myelin from the liver and brain of trout and rat: a new view on the role of fatty acids in membranes.

The content of different phospholipids (PL) and their fatty acid (FA) composition in subcellular fractions from the liver and brain of rat (Rattus rattus) and trout (Salmo irideus) were estimated. It was shown that despite higher content of unsaturated fatty acids in myelin compared to synaptosomes, the unsaturation index of the latter is equal or higher than that of myelin. The total content of PL polyunsaturated fatty acids (PUFA) was shown to be higher in membrane structures with more active ion transport (mitochondria).
