There are two search modes available: simple and advanced. Simple search can include one or more words from the title, summary, keywords or full text, but does not allow the use of search operators. Advanced search allows to limit the number of search results by entering the search terms of different categories in the search window, as well as the use of Boolean search operators (AND, OR and AND NOT). In search results short formats of records are displayed and some data are displayed as links, which open a detailed description of the material (title link) or perform a new search (author or keyword link).

Kinetics of surface wettability of aromatic polymers (PET, PS, PEEK, and PPS) upon treatment with neutral oxygen atoms from non-equilibrium oxygen plasma
Alenka Vesel, Rok Zaplotnik, Gregor Primc, Miran Mozetič, 2024, original scientific article

Abstract: The wettability of polymers is usually inadequate to ensure the appropriate spreading of polar liquids and thus enable the required adhesion of coatings. A standard ecologically benign method for increasing the polymer wettability is a brief treatment with a non-equilibrium plasma rich in reactive oxygen species and predominantly neutral oxygen atoms in the ground electronic state. The evolution of the surface wettability of selected aromatic polymers was investigated by water droplet contact angles deposited immediately after exposing polymer samples to fluxes of oxygen atoms between 3 × 1020 and 1 × 1023 m−2 s −1 . The treatment time varied between 0.01 and 1000 s. The wettability evolution versus the O-atom fluence for all aromatic polymers followed similar behavior regardless of the flux of O atoms or the type of polymer. In the range of fluences between approximately 5 × 1020 and 5 × 1023 m−2 , the water contact angle decreased exponentially with increasing fluence and dropped to 1/e of the initial value after receiving the fluence close to 5 × 1022 m−2

New insights in ATP synthesis as therapeutic target in cancer and angiogenic ocular diseases
Cornelis J. F. van Noorden, Bahar Yetkin-Arik, Paola Serrano Martinez, Noëlle Bakker, Mathilda E. van Breest Smallenburg, Reinier O. Schlingemann, Ingeborg Klaassen, Bernarda Majc, Anamarija Habič, Urban Bogataj, Katrin S. Galun, Miloš Vittori, Mateja Erdani-Kreft, Metka Novak, Barbara Breznik, Vashendriya V. V. Hira, 2024, review article

Abstract: Lactate and ATP formation by aerobic glycolysis, the Warburg effect, is considered a hallmark of cancer. During angiogenesis in non-cancerous tissue, proliferating stalk endothelial cells (ECs) also produce lactate and ATP by aerobic glycolysis. In fact, all proliferating cells, both non-cancer and cancer cells, need lactate for the biosynthesis of building blocks for cell growth and tissue expansion. Moreover, both non-proliferating cancer stem cells in tumors and leader tip ECs during angiogenesis rely on glycolysis for pyruvate production, which is used for ATP synthesis in mitochondria through oxidative phosphorylation (OXPHOS). Therefore, aerobic glycolysis is not a specific hallmark of cancer but rather a hallmark of proliferating cells and limits its utility in cancer therapy. However, local treatment of angiogenic eye conditions with inhibitors of glycolysis may be a safe therapeutic option that warrants experimental investigation. Most types of cells in the eye such as photoreceptors and pericytes use OXPHOS for ATP production, whereas proliferating angiogenic stalk ECs rely on glycolysis for lactate and ATP production.
Keywords: aerobic glycolysis, anaerobic glycolysis, angiogenesis, ATP synthesis, cancer cells, cancer stem cells, endothelial cells, energy metabolism, eye diseases, oxidative phosphorylation, pericytes, retina, Warburg effect

The truncated moment problem on reducible cubic curves I : Parabolic and circular type relations
Seonguk Yoo, Aljaž Zalar, 2024, original scientific article

Abstract: In this article we study the bivariate truncated moment problem (TMP) of degree $2k$ on reducible cubic curves. First we show that every such TMP is equivalent after applying an affine linear transformation to one of 8 canonical forms of the curve. The case of the union of three parallel lines was solved by the second author (2022), while the degree 6 cases by the first author (2017). Second we characterize in terms of concrete numerical conditions the existence of the solution to the TMP on two of the remaining cases concretely, i.e., a union of a line and a circle, and a union of a line and a parabola. In both cases we also determine the number of atoms in a minimal representing measure.
Keywords: truncated moment problems, K-moment problems, K-representing measure, minimal measure, moment matrix extensions
