In previous studies, there are few reports about the influence of pyrethroids on the liver and its damage. Analyzing numerous publications, nuclear factor-ĸB (NF-ĸB) and vascular endothelial growth factor 2 (VEGFR2) seem to be sensitive indicators of microdamages occurring at the cellular level in the liver. The aim of the study was to investigate the effect of subacute poisoning with LCH on the concentration of NFĸB and VEGFR2 in the livers. Methods: The experiment was carried on 32 Albino Swiss mice (16 females and 16 males). The animals were divided into 4 groups. Controls received canola oil, the rest received LCH orally in oil at a dose of 2 mg/kg bw for 7 days. The NF-ĸB and VEGFR2 were mesuredin mice livers with ELISA kits. Results: The mean NF-ĸB concektration in control femals’ livers was 3.27ng/mL and after LCH it was 6.12ng/mL (p<0.05). In control males it was 5.49ng/mL and it did not significantly differ after LCH when it was 5.27ng/mL. The mean VEGFR2 in control females was 84.28ng/mL and after LCH it was 173.81ng/mL (p<0.05). In control males it was 170.61ng/mL and after LCH 170.06ng/mL. Conclusion:The NF-ĸB and VEGFR2 can be used as markers of liver damage after subacute poisoning with LCH on female mice. Females are more sensitive to LCH than males.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"75 1","pages":"57 - 68"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48646679","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}

Currently, governments and industry spend more than 5.7 billion USD annually to control unwanted marine biofouling, aquatic flora and fauna on submerged construction leading to various technical, economical, and ecological problems. In turn, the Baltic Sea is defined as a “time machine” for the future coastal ocean, as processes occurring in the Baltic Sea are related to future changes. Our study describes the biofouling community at 12 sites located at different depths on the legs of the “Baltic Beta” oil platform that resulted in finding a maximum of 1,300 individuals on 400 cm2. We analyzed: spatial distribution of dominant marine organisms living on a steel platform surface, their abundance and mass. Our work showed no significant difference in the benthic samples mass among different depths or cardinal directions of the rig columns. Our research can help to predict offshore biofouling on other devices in the Baltic Sea, to control invasive species and to estimate environmental load.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"75 1","pages":"41 - 56"},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45174534","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}

It promotes the spread of diseases carried by vectors and mass occurrence of arthropods. Millipede can carry infectious agents, invade homes and farms, cause skin irritation in case of exposure to their excretions.The aim of the study was to find information about mass appearances of millipedes and identify the places and periods where it happens. A systematic review of publications available in online scientific databases and the library of the Medical University of Lublin was performed. As many as 5 reports about mass occurrence of millipede were from Japan, 3 from Brazil, 3 from Australia 2 from Germany and Hungary, and single publications from Romania, Norway, Poland and Madagascar. In Japan the 8-year periodicity of millipede outbreaks was observed. Japan and Australia encounter problems at railway due to these organisms. In other countries they are nuisance to people when they enter their dwellings and pose a burden in farming and gardening therefore mechanical, chemical and biological methods of millipede control are tested. On the other hand millipede help in composting organic waste. In conclusion: global climate change is accompanied by an increase in frequency of mass occurrences of millipedes.","PeriodicalId":40385,"journal":{"name":"Polish Hyperbaric Research","volume":"73 1","pages":"81 - 88"},"PeriodicalIF":0.0,"publicationDate":"2020-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48448104","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}

For process reasons, the effectiveness of online process monitoring was evaluated against the previously used periodic sample control by means of laboratory methods of instrumental analysis.

Their values should be kept within certain ranges, however, there are circumstances when it is not possible to maintain control over them.
