The duration of rehabilitation was 7–8 weeks. All children were prescribed a course of additional rehabilitation for 30 days in order to correct microecological imbalance, which included: Biovestin, a dietary supplement in liquid form, containing bifidobacteria of the Bifidobacterium longum MC‐42 strain; the official drug, Kudesan, (active ingredient Coenzyme Q10); and the official drug, Succinic Acid. The assessment of physical, social, educational, emotional and psychological functioning, as well as quality of life as an integrating indicator before and after a comprehensive rehabilitation course using the parental form of the Reds OL Generic Core Scales questionnaire (Russian version) was carried out.After the rehabilitation course, children who underwent MIS‐C associated with SARS‐CoV‐2 showed signs of dysfunction of various organs and systems, which may be the result of an imbalance in the microbial ecosystem and requires mandatory correction. The introduction of a probiotic product and drugs affecting metabolic processes into the rehabilitation course led to a decrease in inflammatory reactions, as well as normalisation of metabolic processes and increased oxygenation, which improved the condition of the children and their quality of life.Federal Research Center for Fundamental and Translational Medicine (FRC FTM), Siberian Branch, Russian Academy of Sciences","PeriodicalId":516742,"journal":{"name":"South of Russia: ecology, development","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141819355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Kumari was used with some modifications. Birds were counted which were transit flying via the territory, as well as birds sitting on the lake water in the area of the observation point.Twenty‐one species of waterfowl have been registered. Analysis of long‐term dynamics has revealed a trend towards a decrease in the total number of migrating waterfowl. In the most abundant species, Anas acuta, this trend is statistically significant. In some species – Anas strepera and Cygnus Cygnus – the trend of dynamics is positive.Most likely reason for the decline in waterfowl numbers is excessive spring hunting. A reduced hunting duration or the introduction of a moratorium every few years may be among the responses required. We suggest using the period of mass migration to monitor the waterfowl resource. This period is shorter and when the greatest number of birds migrate.","PeriodicalId":516742,"journal":{"name":"South of Russia: ecology, development","volume":"122 34","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141820210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The index of physiological state was calculated according to the standard method.Hybrid catfish muscles are characterised as having the greatest nutritional value. In terms of lipid content, the individuals studied belonged to fish with a low fat content, Channa striata, which belongs to the category of lean fish. A high index of physiological state in Oreochromis niloticus was found to be associated with increased water content in muscle tissue. No significant differences were found between the biochemical parameters in the muscles of fish with an increase in body size, and only in Channa striata did the proportion of minerals increase.

The work was carried out at the Scientific Centre of Zoology and Hydroecology, National Academy of Sciences, Republic of Armenia. The material researched also included mollusks and oribatid mites – intermediate hosts of biohelminths.As a result of the study of parasitic invasion of small ruminants in the mountain zone of Armenia, the taxonomic composition of parasites was determined. Helminths found in sheep belong to the classes Trematoda, Nematoda, and Cestoda, protozoa – to the class Protozoa.In the autumn season, representatives of seven genera of parasites of the gastrointestinal tract were found – Moniezia, Dicrocoelium, Fasciola, Nematodirus, Strongylus, Trichuris, Eimeria, while in the summer season, only representatives of five genera were found – Moniezia, Dicrocoelium, Nematodirus, Strongylus, Eimeria.As a result of these studies, it can be concluded that natural and climatic factors of the environment have a significant impact on the structure of the helminth complex of sheep in the mountain region of Armenia.All parasites found can have a detrimental effect on the sheep's body. However, the severity of the invasion in the samples taken is not at the level that could lead to serious diseases in sheep. This suggests that the treatment methods used on farms are at a fairly high level.","PeriodicalId":516742,"journal":{"name":"South of Russia: ecology, development","volume":"112 18","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141820551","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Biological materials from 782 dogs and 189 cats were used in the research, which were examined by methods of complete parasitological autopsy, microscopy and flotation of faecal samples using saturated solutions of zinc sulfate and sodium nitrate.Fourteen parasite taxa have been identified: nematodes (Nematoda) Ancylostoma caninum, Dirofilaria immitis, Toxascaris leonina, Toxocara canis, T. mystax, Uncinaria stenocephala, Taenia sp., T. hydatigena; tapeworms (Cestoda) Diphyllobothrium latum, Dipylidium caninum, Hydatigera taeniaeformis; flukes (Trematoda) Metagonimus sp.; and parasitic alveolates (Conoidasida) Cystoisospora sp., C. felis. The paper presents the values of the prevalence of infection and statistical reliability of their differences for different groups of animals, depending on gender and age. Nematodes were the core taxa of the parasitofauna identified. Explanations for the results obtained are offered and possible sources of human infection are described. Despite the fact that parasitic‐faunal complexes in the ecosystem of a modern city are much less branched and represented by fewer species than in the wild, there remains a high risk of human infection with zoonotic parasites in urban biocenoses due to the high level of intensive population interactions. Therefore, there is a requirement of high alertness of supervisory authorities in relation to anthropozoonotic parasitoses in an urban environment.","PeriodicalId":516742,"journal":{"name":"South of Russia: ecology, development","volume":"115 26","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141820122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
