Label-free detection of the interaction between hexahistidine-tagged human κ-opioid receptor membrane protein and anti-His antibody is demonstrated in liquid by an optical microelectromechanical system utilizing electromagnetically actuated microresonators. Shift in resonance frequency due to accretion of mass on the sensitive surface of microresonators is monitored via an integrated optical re...

We evaluate the ability of hexahistidine (His6) tags on peptide and protein substrates to recruit deoxyribozymes for modifying those substrates. For two different deoxyribozymes, one that creates tyrosine-RNA nucleopeptides and another that phosphorylates tyrosine side chains, we find substantial improvements in yield, kobs, and Km for peptide substrates due to recruiting by His6/Cu(2+). Howeve...

metonymy is one of the ambiguous factors in the literary eloquence. yakobson in his discussion about figurative and metaphoric poles of the language, considers figure substituting process on the vicinity basis and he takes it into account as an obvious characteristic of the prose. where as figure in literary eloquence, especially in contemporary poetry, is considered as an eloquent element beca...

Hardly could any poet, like Al-Mutanabbi, draw to himself the constant attention of scholars, literary man and poets. In this article, we try to find the secret of the admiration that Al-Mutanabbi’s poetry has won and see why he is one of the most preferred poets and considered the prophet of Arab poets. Scholars have studied this issue from various perspectives. In this article, however, I wil...

though the meaning of time seems to be the same for all people, it becomes a complicated, important and relative concept in mysticism which cannot be grasped easily because each mystic understands and interprets it differently depending on the states he experiences; even the same mystic may have diverse interpretations of it in various states and conditions. this paper aims to investigate the s...

We present a molecular theory to study the adsorption of different species within pH-sensitive hydrogel nanofilms. The theoretical framework allows for a molecular-level description of all the components of the system, and it explicitly accounts for the acid-base equilibrium. We concentrate on the adsorption of hexahistidine, one of the most widely used tags in bio-related systems, particularly...

the purpose of the present paper is to investigate semantic deviation of the holy quran in amal donqol's poetry. deviation is one of the techniques of defamiliarization, and was first introduced by the russian formalists in 1917. constructivist attitude toward literary texts and emphasis on the aesthetic aspects of the literary works led formalists to consider literary language as the main...
