Background and objectivesSevere acute respiratory syndrome coronavirus (SARS-CoV) 2 infection has caused millions of deaths worldwide, pushing the urgent need for an efficient treatment. Nonstructural protein 15 (NSP15) is a promising target due to its importance SARS-CoV-2’s evasion host’s innate immune response.

Although parvoviruses are found throughout the animal kingdom, only the human pathogenic B19 virus has so far been shown to possess a limited host range, with erythroid progenitor cells as the main target cells supporting B19 propagation. The underlying mechanism of such erythroid tropism is still unexplained. Synthesis of the NS1 nonstructural protein occurs in permissive and nonpermissive cel...

This paper explores a dual inhibition of main protease (Mpro) and nonstructural protein 10/nonstructural 16 (NSP16) methyltransferase complex as the key targets for COVID-19 therapy. These are based on new Schiff-base ligand that was obtained from condensation (4-chloro-3-methyl phenyl) hydrazine with 2-pyridine-carboxaldehyde its novel metal complexes. include Ni(II), Pd(II), Pt(II), Zn(II), H...

Exceeded losses of nonstructural components from structural ones in most demolished buildings in previous earthquakes and its limitation on functionality of critical facilities and building serviceability after earthquakes should be got the point of view for accounting loss of building as a merit for building performance. This paper attempts to demonstrate the significant role of distribution p...
