background and aims: infectious bronchitis virus (ibv) is the etiological agent of infectious bronchitis (ib), which is an acute and highly contagious disease of the respiratory and sometimes the urogenital tracts of chickens. in iran, the disease has been identified in chicken flocks with serological and virus isolation methods. gene 3c (e) encode envelop (small membrane) protein. for envelope...

Objective(s): Production of a recombinant and immunogenic antigen using dengue virus type-3 envelope protein is a key point in dengue vaccine development and diagnostic researches. The goals of this study were providing a recombinant protein from dengue virus type-3 envelope protein and evaluation of its immunogenicity in mice. Materials and Methods: Multiple amino acid sequences of different i...

lentiviral vectors are among the promising viral based-vectors in gene therapy applications, but the efficiency of their targeting needs to be improved. (strept)avidin-biotin adaptor system is a novel approach to modify the lentiviral envelope for better targeting properties. herein, we describe utilization of this adaptor system by designing a candidate envelope protein-bearing biotin acceptor...

regarding the role and importance of subsurface drainage in water table control, many studies have been made throughout the world to find out new techniques and more economical solutions, especially as related to different pipe envelope material and their installations. this research was conducted to investigate the use of rice husk, as drain envelope material, in drainage installations. in add...

The complete laboratory data of 24 samples with confirmed coronavirus Disease-2019 were retrieved by nucleic acid testing, and the quantification SARS-CoV-2 World Health Organization (WHO) envelope (E-gene), RNA-Dependent RNA Polymerase (RdRP-gene), Nucleocapsid (N-gene) three primers Roche Cobas z 480. Throat or nasopharyngeal swabs reports demonstrated primer Cross Points (CPs) greater than 2...

The bacterial envelope integrates essential stress-sensing and adaptive functions; thus, envelope-preserving functions are important for survival. In Gram-negative bacteria, envelope integrity during stress is maintained by the multi-gene Psp response. Mycobacterium tuberculosis was thought to lack the Psp system since it encodes only pspA and no other psp ortholog. Intriguingly, pspA maps down...
