COVID-19 remains one of the main challenges of healthcare, given growing numbers of people with COVID-19 in anamnesis, and given the long-lasting consequences and complications of this disease. Cancer is one of the most common diseases in the world, thus a big part of the population is affected by both COVID-19 and cancer. In this succinct review we refer to several recent works expressing a view that COVID-19 might be oncogenic, and describe molecular mechanisms of such phenomena. Next, we describe several tumorigenic changes in the tissue microenvironment as COVID-19 sequelae, which can potentially affect cancer pathogenesis and response of a tumor to therapy. 3D cell culture models are a “golden standard” of in vitro studies in translational oncology. To the best of our knowledge, 3D cell culture systems to study tumor behavior in the tissue microenvironment affected by COVID-19 have not been developed yet. We propose several actionable steps which can be taken to modify existing 3D cell culture models accordingly, to address the needs of translational oncology in the COVID-19 post-pandemic times.","PeriodicalId":8998,"journal":{"name":"Biological Communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139196759","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}

Ethanolic extract significantly stimulated cell migration and cultured mineralization with respect to control, showing the maximal effect at a dilution 1/5000. Together, the results show that the A. arborescens extracts do not have toxic effects.

The Department of Genetics and Biotechnology of St. Petersburg State University is the oldest department of genetics in Russia, founded in 1919. Throughout the entire period of development, the geneticists of St. Petersburg University have collected unique forms of plants, animals and microorganisms, on which their research was based. Many of these studies including regulation of translation termination in yeast, amyloids and prions of different organisms, genetic mapping of valuable morphological and biochemical traits to create first rye chromosome maps, and several aspects of transcription regulation in plants, had a significant novelty. The most active accumulation of collections of genetic resources at St. Petersburg State University started in the 1950-1970s when important scientific directions in the genetics of microorganisms, plants and animals, many of which continue today, were established at the department. Genetic collections are actively used in educational work for teaching dozens of educational courses. Currently, the interdisciplinary genetic collections of St. Petersburg State University consist of seven sections including genetic collections of rye, radish, garden pea, Chlamydomonas algae, Saccharomyces yeast and plasmids, Komagataella yeast, Drosophila fly.

The vector and extent of these changes depend, inter alia, on the type of lime material and the doses used. Particularly, excessive liming can trigger a deficiency of manganese for crops. A long-term microfield experiment (13 test years) was carried out on Albic Retisols reclaimed with the dolomite particles of various sizes as a by-product of stone processing quarries. Ten treatments including various sized dolomite particles and their combinations, as well as traditional limestone flour on the background of NPK fertilizer were studied for the changes in soil acidity indicators (exchangeable acidity, pH; hydrolytic acidity, Hy; total acidity, Htot) and manganese availability. The amount of acidic components passing into the extract of 1N KCl was insufficient to reveal a dependency between the exchangeable acidity and the content of mobile manganese in the soil of most treatments limed with dolomite particles of various sizes. However, the relationship between the content of mobile Mn in soils and the value of hydrolytic acidity was proved by paired linear regressions. Regardless of the dose and size of dolomite particles added, the soil was highly and moderately supplied with plant available manganese during the entire study period.","PeriodicalId":8998,"journal":{"name":"Biological Communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139205121","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}

Our goal was to assess how sex differences mediate relationships between cognitive flexibility, affective state, hierarchy and ethanol preference before and after chronic intermittent ethanol (CIE) exposure in Wistar rats. The results of our study revealed sex-dependent changes in ethanol preference and locomotor activity throughout the time. Anxiety levels were sex-dependently affected by ethanol exposure with a dramatic decrease in ethanol-exposed females. Similarly, striatal tyrosine hydroxylase expression was affected by CIE in a sex-dependent manner, with ethanol-exposed females having higher expression than males. Baseline cognitive flexibility was better in rats with higher locomotor activity and lower anxiety levels but did not correlate with ethanol preference in rats. Taken together, these results are important for understanding sex-dependent alterations in brain and behavior induced by alcohol. This provides important insights into understanding sex differences in the risk for mental disorders.","PeriodicalId":8998,"journal":{"name":"Biological Communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139201958","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}

Epidermis of four species of Gnetum L. and four species of Jurassic Bennettitales (Nilssoniopteris Nathorst and Ptilophyllum Morris) was studied. The coefficients of variation for epidermal characters Gnetum range from 6.4 to 24.0 %, Ptilophyllum — 15.7–63.5 % and Nilssoniopteris — 18.0–39.9 %. In both groups of plants, the sinuosity of the tangential cell walls of the epidermal cells in the upper and lower epidermis is a stable character (Cv ≤ 18.0 %). In the Ptilophyllum and Gnetum, the length of stomata demonstrates a low level of variability (Cv ≤ 16.8 %). A significant range of the coefficients of variation in both Gnetum and Bennettitales show the number of epidermal cells per 1 mm2 of the upper and lower epidermis (17.5 % ≤ Сv ≤ 31.9 %), the area of the epidermal cells in the upper and lower epidermis (21.2 % ≤ Сv ≤ 63.5 %) and the number of stomata per 1 mm2 of epidermis (29.3 % ≤ Сv ≤ 39.9 %). Similarities in the correlation structure of the epidermal characters are revealed in correlations between sinuosity of the tangential cell walls of the epidermis, the number of stomata per 1 mm2 and their size; the length of stomata and the number of epidermal cells; stomatal index and the number of epidermal cells of the epidermis. In Gnetum, the number of differentiated stomata correlates with the number of aborted stomata. In N. angustifolia and P. caucasicum, the number of stomata correlates with the number of papillae per 1 mm2. Similarities in correlational structure of epidermis in Nilssoniopteris, Ptilophyllum, and Gnetum could be ecological adaptations or ontogenetic characters, such as the development of stomata that has been described by other researchers.","PeriodicalId":8998,"journal":{"name":"Biological Communications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46024859","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}
