iron deficiency in soil reduces the quality of durum wheat leading to fe deficiency in human. thus, this experiment investigated the effects of foliar application of nano-iron oxide (2 and 4 g l-1), iron chelate (edta), (4 and 8 g l-1), iron sulfate (4 and 8 g l-1), and the control on grain yield and quality, yield components, chlorophyll and carotenoids contents, peroxidase (pox), catalase (ca...

A novel coronavirus, known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), enters into the host cells through an interaction between its surface spike protein (S-protein) and angiotensin-converting enzyme receptors, leading to disease 2019 (COVID-19). Using effective S-protein inhibitors may reduce virulence of virus. Molecular docking was performed evaluate binding affinity 97...

Structural characterization of protein-protein interactions is essential for our ability to understand life processes. However, only a fraction of known proteins have experimentally determined structures. Such structures provide templates for modeling of a large part of the proteome, where individual proteins can be docked by template-free or template-based techniques. Still, the sensitivity of...

objectives the overall goal of this study was to carry out a set of comparative analyses of arsr gene in plasmid r773 and bacterial chromosome from escherichia coli bl-21(de3). methods pdb and ncbi databases and chimera, mega4, clc main workbench software and 3d-jigsaw and embl-ebi servers were applied to perform this study. by using these software and servers, multiple analyses including deter...
