Three (control, buffer, and impact) zones of the pollution gradient were identified based on the contents of main polluting elements (S, Ni, and Cu) in the forest litter. A significant weakening of pine stands was observed in the impact zone and attributed to the combined effect of long-term anthropogenic pollution of the 1970s and unfavorable weather events of the mid-1980s. As the emission decreased from 1988 to 2018, the radial increment of P. sylvestris was observed to increase significantly (by up to 44%) in the impact zone and to remain much the same in the control and buffer zones. More recently, the radial increment of trees in the impact zone reached and even exceeded the values observed in the control zone, although the trees examined were relatively old. The finding demonstrated again the high adaptive capacity of P. sylvestris.","PeriodicalId":11351,"journal":{"name":"Doklady Biological Sciences","volume":" ","pages":"205-217"},"PeriodicalIF":0.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141916383","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}

Adipose tissue samples were collected from two Caspian seals (Pusa caspica Gmelin, 1788) found dead on the Caspian Sea shore in 2020. Organochlorine pesticides, primarily DDT and HCH, and polychlorinated biphenyls (PCBs) were major pollutants found in the Caspian seals. The distribution of metabolites indicated the absence of recent pesticide use. The PCB content was relatively high, but still at the lower limit of the range of values determined previously, as was also the case with pesticides. Chlordanes, polychlorinated naphthalenes, and polybrominated diphenyl ethers were detected in minor quantities and were therefore not considered to be major pollutants of the Caspian seal. The pollutant levels were below a threshold at which a distinct effect on seal health can be expected. High-resolution accurate mass (HRAM) spectrometry was found to provide a convenient tool for both targeted and nontargeted analyses of a wide range of organic pollutants in a single experiment.","PeriodicalId":11351,"journal":{"name":"Doklady Biological Sciences","volume":" ","pages":"107-111"},"PeriodicalIF":0.0,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141916384","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}

Small cankers or canker parts were placed in a humid chamber. Fungi were identified by morphological features. Sorocybe resinae (Fr.) Fr. and Penicillium glaucoalbidum (Desm.) Houbraken & Samson were the most common. The S. resinae occurrence was 75.9 ± 7.9%. The fungus developed in the surface layers of dried resin, but was not detected in the absence of resin production. The fungus S. resinae was therefore assumed to be a nearly ubiquitous component of the mycobiota of resinous cankers on spruce trunks in Leningrad Oblast. The fungus P. glaucoalbidum has only been observed as a saprotroph in Russia earlier. Weak pathogenic properties were detected in the species in experiments; i.e., P. glaucoalbidum grew on live bark tissues in a humid chamber. Based on its high occurrence (41.4 ± 9.1%), P. glaucoalbidum was identified as a regular component of the microbiota in spruce necrotic canker. Pure cultures of P. glaucoalbidum and Oidiodendron sp. were obtained. To test the respective species as possible causative agents of trunk canker, trunks of 20 spruce trees were inoculated with the fungal cultures in a forest stand. The cultures stimulated resin secretion without causing necrosis to spread beyond the inflicted wound. To better understand the phenomenon, a more detailed study of the biota in necrotic cankers is necessary to perform with a special focus on their nonpathogenic part, which has not received proper attention as of yet.","PeriodicalId":11351,"journal":{"name":"Doklady Biological Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142282044","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}

Preoperative stress increases the risk of myocardial injury after noncardiac surgery (MINS). The mechanisms of MINS are poorly understood. Lack of physical activity and the development of weakness and fatigue are consequences of many noncardiac surgery types. The relationship between surgery and changes in the morphofunctional state of muscles in the postoperative period is still unclear now. The study showed for the first time that metabolic and hormonal changes caused by preoperative stress + surgery or surgery alone underlie MINC in the postoperative period in C57BL/6 mice. Minor increases in triglyceride-glucose (TyG) index were for the first time identified as indicative of ischemic/hypoxic damage to the myocardium and skeletal muscles. More research is necessary to perform to better understand the effects of preoperative stress and noncardiac surgery on the myocardium and muscle performance, as well as the risks and benefits of perioperative treatment.","PeriodicalId":11351,"journal":{"name":"Doklady Biological Sciences","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142282043","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}
