Strain Wars: Competitive interactions between SARS-CoV-2 strains are explained by Gibbs energy of antigen-receptor binding
(Elsevier, 2022)
Since the beginning of the COVID-19 pandemic, SARS-CoV-2 has mutated several times into new strains, with an increased infectivity. Infectivity of SARS-CoV-2 strains depends on binding affinity of the virus to its host ...
Food Antioxidants and Their Interaction with Human Proteins
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
Common to all biological systems and living organisms are molecular interactions, which
may lead to specific physiological events. Most often, a cascade of events occurs, establishing an
equilibrium between possibly ...
Anisotropic grossular-andradite garnets: Evidence of two stage skarn evolution from Rudnik, Central Serbia
(Earth Science Institute of the Slovak Academy of Sciences, 2021)
This paper presents LA-ICP-MS data for garnets from the Rudnik skarn deposit (Serbia), which range from Grs45–58Adr40–52Alm2–3 in the core and Adr70–97Grs2–29Sps1 in the rim displaying anisotropy and zoning. In spite of ...
Rietveld crystal structure refinement of a natural rhombohedral grossular-andradite garnet from Serbia
(Polish Geological Institute - National Research Institute, 2022)
Four macroscopically visible B–E (rim) zones, within a large natural ferric grossular garnet of Grs58–64Adr36–42Sps2 composition, are described by means of Rietveld refinements of the crystal structures in a series of six ...
The effect of gamma irradiation on the synthesis, microbiological sterility, and improvement of properties of PMMA-Al2O3 composite used in dental prosthesis manufacturing
(Radiation Physics and Chemistry, 2023)
Polymethyl methacrylate (PMMA) is a polymer material widely used in dental applications due to its excellent biocompatibility, stable physicochemical properties, easy manipulation, and low cost. The combination of biocompatible ...
Ligand binding to fibrinogen influences its structure and function
(University of Novi Sad - Faculty of Sciences, Department of Biology, 2021)
Fibrinogen is a plasma protein that is highly susceptible to oxidation. Because of this chemical modification, fibrinogen acquires thrombogenic characteristics under different pathophysiological conditions. Increased ...
Strain wars 2: Binding constants, enthalpies, entropies, Gibbs energies and rates of binding of SARS-CoV-2 variants
(Elsevier, 2021)
SARS-CoV-2 virus is the cause of COVID-19 pandemic and belongs to RNA viruses, showing great tendency to mutate. Several dozens of mutations have been observed on the SARS-CoV-2 virus, during the last two years. Some of ...
Never ending story? Evolution of SARS-CoV-2 monitored through Gibbs energies of biosynthesis and antigen-receptor binding of Omicron BQ.1, BQ.1.1, XBB and XBB.1 variants
(Elsevier, 2023)
RNA viruses exhibit a great tendency to mutate. Mutations occur in the parts of the genome that encode the spike glycoprotein and less often in the rest of the genome. This is why Gibbs energy of binding changes more than ...
Omicron BA.2.75 subvariant of SARS-CoV-2 is expected to have the greatest infectivity compared with the competing BA.2 and BA.5, due to most negative Gibbs energy of binding.
(MDPI, 2022)
Omicron BA.2.75 may become the next globally dominant strain of COVID-19 in 2022. The BA.2.75 sub-variant has acquired more mutations (9) in spike protein and other genes of SARS-CoV-2 than any other variant. Thus, its ...
Omicron BA.2.75 Sublineage (Centaurus) Follows the Expectations of the Evolution Theory: Less Negative Gibbs Energy of Biosynthesis Indicates Decreased Pathogenicity
(MDPI, 2022)
SARS-CoV-2 belongs to the group of RNA viruses with a pronounced tendency to mutate. Omicron BA.2.75 is a subvariant believed to be able to suppress the currently dominant BA.5 and cause a new winter wave of the COVID-19 ...
