Abstract
In this work, we have extended our previously proposed approach for determining protein concentrations in human serum (using MALDI-TOF mass spectrometry) to include simultaneous analysis of several proteins associated with acute inflammation (alpha-2-macroglobulin, fetuin-A, serum amyloid A1). This technique can be used to diagnose systemic inflammation and provides results in 4-5 h. The developed approach was verified using standard immunological methods (ELISA). Samples from 87 individuals, in specific groups, were used for testing and validation: control; inflammatory soft tissue disease accompanied by sepsis; influenza A infection; or COVID-19. The feasibility of differentiating patient groups with the aforementioned conditions was analyzed using a combination of the inflammatory markers described. For fetuin-A and serum amyloid A1, diagnostically significant concentration ranges were established.

Abstract
Two influenza A nucleoprotein variants (wild-type: G102R; and mutant: G102R and E292G) were studied with regard to macro-molecular interactions in oligomeric form (24-mers). The E292G mutation has been previously shown to provide cold adaptation. Molecular dynamics simulations of these complexes and trajectory analysis showed that the most significant difference between the obtained models was distance between nucleoprotein complex strands. The isolated complexes of two ribonucleoprotein variants were characterized by transmission electron microscopy and differential scanning fluorimetry (DSF). Presence of the E292G substitution was shown by DSF to affect nucleoprotein complex melting temperature. In the filament interface peptide model, it was shown that the peptide corresponding in primary structure to the wild-type NP (SGYDFEREGYS) is prone to temperature-dependent self-association, unlike the peptide corresponding to E292G substitution (SGYDFGREGYS). It was also shown that the SGYDFEREGYS peptide is capable of interacting with a monomeric nucleoprotein (wild type); this interaction's equilibrium dissociation constant is five orders of magnitude lower than for the SGYDFGREGYS peptide. Using small-angle neutron scattering (SANS), the supramolecular structures of isolated complexes of these proteins were studied at temperatures of 15, 32, and 37 °C. SANS data show that the structures of the studied complexes at elevated temperature differ from the rod-like particle model and react differently to temperature changes. The data suggest that the mechanism behind cold adaptation with E292G is associated with a weakening of the interaction between strands of the ribonucleoprotein complex and, as a result, the appearance of inter-chain interface flexibility necessary for complex function at low temperature.Communicated by Ramaswamy H.

Abstract
Upper respiratory tract infections are the world's most common infectious disease. The etiologic agents behind upper respiratory tract infections (URTIs) are, in fact, a diverse set of pathogens such as influenza, parainfluenza, adenovirus, rhinovirus, and others. More than 200 pathogens are known to be involved. Differential diagnosis of viral infections is sometimes complicated by their diversity or similarity of clinical presentation. This work is devoted to the development of a method which enables simultaneous detection of six common viral URTI pathogens: IAV; IBV; RSV; hAdV; hPIV2; and hPIV3. Antibody microarray technology is utilized to accomplish the analysis. In preparation for protein microchip creation, we produced, characterized, and selected approximately 50 monoclonal antibodies; for each of the aforementioned pathogens, an optimal monoclonal antibody pair was selected. A protein microchip was created, and its core working conditions were optimized. With a balance between convenience and maximal assay sensitivity in mind, a one-step analysis approach was developed for accomplishing the ELISA-like "sandwich" interaction on the manufactured microchip (antibody microarray). Reference viral strains were used to establish the lower limits of detection (LoD) for the assay. For IAV, the LoD was 0.25 ng/ml total viral protein. For other viruses, the LoD ranged from 1 to 2 ng/ml total protein. These sensitivity limits are slightly better than those of standard ELISA, but inferior to those of PCR. Overall, we believe that the developed microchip is a good alternative to existing methods, allowing relatively quick (overnight), inexpensive, simultaneous screening of several pathogens. The design of the antibody microarray is conducive to further development, and the panel of analyzed pathogens can be expanded to include approximately 50 members.
