Copper is essential for maintaining the life processes in all living cells, because several copper-dependent enzymes\u0000 play an important role in key physiological processes like cellular respiration, oxygen radical scavenging, the transport of iron and neurotransmitter synthesis. Maintaining copper homeostasis implies maintaining the constancy of copper levels in the cells and fluids throughout the body, in\u0000 order to support the enzymes and other factors that underlie normal life processes. Therefore, living organisms have developed complex mechanisms for maintaining their physiological copper level, because an excess copper level can be toxic for the cells. In the cell, copper homeostasis is\u0000 controlled by a network of copper-binding proteins and transporters. Furthermore, copper uptake is mediated by the membrane transporter CTR1 and CTR2 proteins. In the cytoplasm, it is bound to a unique group of metallochaperones (ATOX1, CCS COX17) and transported to different cell compartments,\u0000 where it is linked to the recipient proteins. The Cu-transporting ATPases (ATP7A and ATP7B) are responsible for transferring copper into the Golgi apparatus, where the copper is added to the active sites of enzymes, and it is also directed onto the path of excess cellular copper removal to\u0000 prevent the occurrence of toxicity.","PeriodicalId":50438,"journal":{"name":"Folia Biologica-Krakow","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45628286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Its tolerance to a broad range of environmental conditions has favoured its success in colonising new environments worldwide. However, population\u0000 crashes may occur, leading to significant fluctuations in snail densities. Such crashes might be linked to morphological changes in the shell whorls, like the emergence of a haired keel (carinatus morphotype). In this study, we investigated the link between the appearance of the carinatus\u0000 morphotype and the crashes in population densities over three years, based on field observations. The presented results show that after the emergence of the so-called carinatus morphotype, the population of P. antipodarum collapsed and did not recover for the next two years.\u0000 This may indicate that the carinatus morphotype is a defensive reaction to extremely unfavourable environmental conditions.","PeriodicalId":50438,"journal":{"name":"Folia Biologica-Krakow","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48263091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to examine the effects of a 6-h in vitro treatment of livers isolated from 14-day-old chicken embryos with NaF at doses of 1.7 (D1), 3.5 (D2), 7.1 (D3)\u0000 and 14.2 mM (D4), with regard to apoptosis, cell proliferation and tissue structure. The mRNA expression of the apoptosis regulators CYCS, APAF1, BCL2, CASP3, CASP9 and TMBIM1 was analysed by the qPCR method. Apoptotic cells were detected by a TUNEL\u0000 assay. The tissue and DNA structure were also analysed by histological staining (H&E, Feulgen). The number of proliferating cells was determined and the apoptosis regulatory proteins were localised by the immunohistochemical staining of PCNA, CASP3 and APAF1. The results showed that the\u0000 mRNA expression of CYCS, BCL2, CASP3, CASP9 and APAF1 increased significantly in the D1 group, as did that of CASP9 in the D3 group and of BCL2 and APAF1 in the D4 group. The number of apoptotic cells increased significantly in the\u0000 D4 group, where they increased from 18% to 49%. On the other hand, the number of proliferating cells decreased gradually, in a dose-dependent manner, from 84% in the control group to 5.5% in the D4 group. The expression of apoptosis-regulating factors also increased: in the D3 and D4 groups,\u0000 the CASP3 immunopositive reaction was more intensive in single cells in the embryonic livers, whereas that of APAF1 increased in the hepatocytes as well as in the hepatic blood vessel walls. The mechanism of the effect of NaF on apoptosis in the embryonic liver is very complex. In the groups\u0000 exposed to higher doses of NaF, apoptosis was significantly stimulated, while proliferation was inhibited and the tissue structure was damaged. The expression of apoptosis regulators at the mRNA and protein levels increased, but the mRNA expression did not depend on the NaF dose. These results\u0000 reveal that NaF, by changing the balance between apoptosis and the proliferation of hepatocytes, may disturb the development and function of the liver in embryonic chickens. Therefore, the risk of exposure to NaF should be considered when determining the standards for human and animal exposure\u0000 to this compound.","PeriodicalId":50438,"journal":{"name":"Folia Biologica-Krakow","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44477480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The morphological characteristics of the C. distinctus propupa and pupa represent their adaptations to moulting in the soil, not on the host plant. The study of the biology of C. distinctus is supplemented\u0000 by an analysis of the impact of the foraging by this insect on its host plant Convallaria majalis. Based on the morphological, anatomical and histological analyses of Lily of the Valley leaves, we show that both adults and larval instars feed on the epidermal cells of both the upper\u0000 and lower sides of the leaf blade in C. majalis. However, the assimilation parenchyma cells located immediately below the epidermis at the feeding site retain their shape.","PeriodicalId":50438,"journal":{"name":"Folia Biologica-Krakow","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45268531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The used concentrations corresponded to 1 and 5 mg/l of\u0000 the active ingredient (glyphosate potassium salt). The haematological analysis performed showed a decrease of the RBC count, as well as an increase of the other erythrocyte indices (Hb, MCV, MCH, MCHC). Most of these changes were dependent on the concentration and time. An increase of the\u0000 WBC count and the percentage of immature neutrophils occurred, thus indicating the presence of inflammation. In the studied blood biochemical parameters, only minor and temporary changes were observed. The histopathological analysis revealed no alterations in the gills, liver and kidney.

Amphibians are known as a vulnerable group of vertebrates that live and reproduce in both terrestrial and aquatic habitats. The subtropical regions of the world are among the land areas where amphibians will suffer the most from climate change. In the present study, the effect of climate change on Bufo eichwaldi inhabiting Hyrcanian forests was investigated. According to our results, the lowest temperature in the coldest season is the most important variable for the presence of this species. Due to the beginning of reproductive activity and mating taking place in late January until the end of February, this variable will have a direct effect on the rate of breeding and thus on the conservation of this species, because the species can find a new suitable area outside of high humanisation and increase its chance of successful breeding. Of course, climate change will cause the average annual temperature to rise by 2070, and this will favour the early onset of reproduction. Therefore, according to the analysis and scenarios considered in this study, global warming cannot have a negative effect on the toad species. However, a careful assessment of the status of other competing species in conjunction with the Talysh toad could provide a better explanation of the impact of climate change.","PeriodicalId":50438,"journal":{"name":"Folia Biologica-Krakow","volume":" ","pages":""},"PeriodicalIF":0.7,"publicationDate":"2022-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45182919","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
