Could Inelastic Interactions Induce Quantum Probabilistic Transitions?
What are quantum entities? Is the quantum domain deterministic or probabilistic? Orthodox quantum theory (OQT) fails to answer these two fundamental questions. As a result of failing to answer the first question, OQT is very seriously defective: it is imprecise, ambiguous, ad hoc, non-explanatory, inapplicable to the early universe, inapplicable to the cosmos as a whole, and such that it is inherently incapable of being unified with general relativity. It is argued that probabilism provides a very natural solution to the quantum wave/particle dilemma and promises to lead to a fully micro-realistic, testable version of quantum theory that is free of the defects of OQT. It is suggested that inelastic interactions may induce quantum probabilistic transitions
Zika virus infection elicits auto-antibodies to C1q
Zika virus (ZIKV) causes mostly asymptomatic infection or mild febrile illness. However, with an increasing number of patients, various clinical features such as microcephaly, Guillain-Barré syndrome and thrombocytopenia have also been reported. To determine which host factors are related to pathogenesis, the E protein of ZIKV was analyzed with the Informational Spectrum Method, which identifies common information encoded by primary structures of the virus and the respective host protein. The data showed that the ZIKV E protein and the complement component C1q cross-spectra are characterized by a single dominant peak at the frequency F = 0.338, suggesting similar biological properties. Indeed, C1q-specific antibodies were detected in sera obtained from mice and monkeys infected with ZIKV. As C1q has been known to be involved not only in immunity, but also in synaptic organization and different autoimmune diseases, a ZIKV-induced anti-C1q antibody response may contribute to the neurological complications. These findings might also be exploited for the design of safe and efficacious vaccines in the future
In vitro anti-influenza activity of in silico repurposed candidate drug Cycrimine
Background: Due to the limitations of current antiviral therapies because of drug resistance and the emergence of new circulating viral strains, novel effective antivirals are urgently needed. Results of the previous drug repurposing by virtual screening of DrugBank revealed the anticholinergic drug cycrimine as a possible inhibitor of the influenza virus infection. Methods: In this study we examined the potential antiviral activity of cycrimine in vitro. Results: The experimental results showed the anti-influenza activity of cycrimine against two different influenza A subtypes in cell culture. Conclusions: The findings of this study suggest cycrimine as a potential therapeutic agent for influenza. ©2019 International Medical Press
Exploring the Antiviral Potential of Natural Compounds against Influenza: A Combined Computational and Experimental Approach
The influenza A virus nonstructural protein 1 (NS1), which is crucial for viral replication
and immune evasion, has been identified as a significant drug target with substantial potential to
contribute to the fight against influenza. The emergence of drug-resistant influenza A virus strains
highlights the urgent need for novel therapeutics. This study proposes a combined theoretical
criterion for the virtual screening of molecular libraries to identify candidate NS1 inhibitors. By
applying the criterion to the ZINC Natural Product database, followed by ligand-based virtual
screening and molecular docking, we proposed the most promising candidate as a potential NS1
inhibitor. Subsequently, the selected natural compound was experimentally evaluated, revealing
measurable virus replication inhibition activity in cell culture. This approach offers a promising
avenue for developing novel anti-influenza agents targeting the NS1 protein.This research was funded by Ministry of Science, Technological Development and Innovation of the Republic of Serbia, grant number 451-03-66/2024-03/200017.info:eu-repo/semantics/publishedVersio
