the effects of electromagnetic fields (emfs) radiation at the frequency of 940 mhz on the structure and function of human adult and fetal hemoglobin (hba and hbf) were studied. after extraction and purification of hba and hbf, the oxygen absorption values for exposed and unexposed hba and hbf to emf were compared. the slope of oxygen absorption curve for exposed hba was increased while that for...

The structural characterization of peripheral membrane proteins represents a tremendous challenge in structural biology due to their transient interaction with the membrane and the potential multitude of protein conformations during this interaction. Neutron reflectometry is uniquely suited to address this problem because of its ability to structurally characterize biological model systems nond...

Gilead, Zvee (University of Pennsylvania, Philadelphia), and Harold S. Ginsberg. Characterization of a tumor-like antigen in type 12 and type 18 adenovirus-infected cells. J. Bacteriol. 90:120-125. 1965.-An antigen that reacts with antibody from type 12 adenovirus tumor-bearing hamsters was identified in extracts of KB cells infected with type 12 or 18 adenovirus. In contrast, viral structural ...

Background: Coronaviruses are positive single-stranded RNA viruses that have a spherical shape and some spike-shaped proteins (spike proteins) project from their surface, which they derive name because resemble solar corona. The sequence of SARS-CoV-2 is approximately thirty thousand nucleotides in length encodes both structural non-structural proteins. Objective: To assess the relation between...

Infectious bronchitis virus (IBV) is a contagious pathogen in fowl that results in economic loss in the poultry industry. In this study, the amino acids sequences of three structural proteins M, N, and S1 for five Iranian IBV isolated during 1998-2011 have been analyzed. Conserved and variable regions, hydrophobic characteristics and identity matrix were determined after alignment by Bioedit ve...
