Novel COVID-19 Intersections with Dentistry: Approaches to protection
2021
Background: COVID-19 outbreak brought many challenges to the society and to health care systems Health care professionals in dental practices are a high-risk population, due to close contact to saliva and aerosols Specific guidance for those professionals is essential to control disease transmission and guarantee dentist's health Material and Methods: We performed a literature review based on online search in Pubmed, Scientific Electronic Library, Literatura Latino-Americana e do Caribe em Ciencias da Saude and Scopus databases Included articles were fully read and analysed regarding infection control measurements, use of personal protective equipment (PPE), conditions for procedures and us…
Caffeine analysis and extraction from a topical cream intended for UV-skin protection
2020
Made available in DSpace on 2021-06-25T10:16:59Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-01 This study aimed to develop and validate a method for the analysis of caffeine in complex cosmetic samples, such as sunscreens. Besides, an extraction method of caffeine from coffee oil and from creams, which contains both lipophilic and hydrophilic components, has been developed. The method to analyze caffeine was developed using an isocratic pump, Waters 1515 and an automatic injector Perkin-Elmer Series 200 and an UV detector Perkin-Elmer. As stationary phase, Kromasil C-18 (150 × 4.6 mm ID with particle size of 5 µm) column was used and a mixture of water (pH 4.00)/acetonitrile (…
Cilium induction triggers differentiation of glioma stem cells
2020
Glioblastoma multiforme (GBM) possesses glioma stem cells (GSCs) that promote self-renewal, tumor propagation, and relapse. GBM has a poor prognosis, and currently, there are no curative options exist. Understanding the mechanisms of GSCs self-renewal can offer targeted therapeutic interventions. However, insufficient knowledge of the fundamental biology of GSCs is a significant bottleneck hindering these efforts. Here, we show that patient-derived GSCs recruit an elevated level of proteins that ensure the temporal cilium disassembly, leading to suppressed ciliogenesis. Depleting the cilia disassembly complex components at the ciliary base is sufficient to induce ciliogenesis in a subset of…
Cilium induction triggers differentiation of glioma stem cells.
2020
Glioblastoma multiforme (GBM) possesses glioma stem cells (GSCs) that promote self-renewal, tumor propagation, and relapse. Understanding the mechanisms of GSCs self-renewal can offer targeted therapeutic interventions. However, insufficient knowledge of GSCs' fundamental biology is a significant bottleneck hindering these efforts. Here, we show that patient-derived GSCs recruit elevated levels of proteins that ensure the temporal cilium disassembly, leading to suppressed ciliogenesis. Depleting the cilia disassembly complex components is sufficient to induce ciliogenesis in a subset of GSCs via relocating platelet-derived growth factor receptor-alpha (PDGFR-α) to a newly induced cilium. Im…
Climate Conference in Katowice (COP24) and Statement of Polish Power Representatives about Energetic Policy under the prism of domestic opinion-formi…
2019
The following article is concerned on the press discourse which was created on the background of the climate conference, COP24, in Katowice (the event took place from 3 to 15 December 2018).Author of the research, by means of content analysis and critical discourse analysis, researched the following press titles: “Gazeta Wyborcza”, “Polityka”, “Rzeczpospolita”, “Do Rzeczy” and “Nasz Dziennik”. Then, author chose that articles, that were dealt about session of climate summit in Katowice, and he studied them under the perspective of three subjects: 1) hopes, which press commentators had in case of COP24; 2) opinions about official statements of Polish politicians during conference’s inaugurat…
La Natura come soggetto di diritto: l'approccio ecuadoriano
2022
All legal systems by now must confront the issue of environmental protection. The scope of this paper is to analyse the Ecuadorian approach, considering that it is the only legal system which, so far, has constitutionalized the rights of Nature, thus allowing a change in the status of Nature, from object to subject of law, overcoming the traditional approach of Western environmental law. The paper also aims to show how the theme of the rights of Nature offers a valuable opportunity for intercultural dialogue, and how the Ecuadorian experience represents, in this sense, a perfect mix between Western legal notions, such as damage, protection, or representation, and the ancestral knowledge of …
A geomorphological approach for enhancing environmental management and conservation of landforms as protected nature objects in the Upper Daugava spi…
2015
<p class="R-AbstractKeywords"><span lang="EN-GB">This paper describes the application of geomorphological approach for environmental management and conservation of landforms. Specifically, we discuss the contribution of geomorphological field survey and adapted matrix methodology (in combination with understanding of geology) to identification, study and evaluation of those abiotic nature elements which represent geological and geomorphological heritage. We describe a case study carried out in that part of the protected landscape area “Augšdaugava” which encompasses the Upper Daugava spillway valley. The study programme reported in this paper was realized to perform inventory of…
