Plato, as a poet, employs muthos extensively to express his philosophical dialectical development, so the majority of his dialogues are comprised of muthoi. We cannot separate his muthos from his philosophical thought, since the former has great influence in the latter. So the methodology of this paper is first to discuss the dialogue Theaetetus to find out why he compares Socrates to the Greek...

We have expressed recombinant RNase P protein from Escherichia coli in high yield. A hexahistidine sequence at the amino terminus allowed protein purification in a single step. Mass spectrometry confirmed the molecular weight of the purified protein and indicated a purity of > 95%. Protein functionality was demonstrated by reconstitution of active holoenzyme.

Site-specific fluorescent labeling of proteins in vivo remains one of the most powerful techniques for imaging complex processes in live cells. Although fluorescent proteins in many colors are useful tools for tracking expression and localization of fusion proteins in cells, these relatively large tags (>220 aa) can perturb protein folding, trafficking and function. Much smaller genetically enc...

BACKGROUND Making peptide pharmaceuticals involves challenging processes where many barriers, which include production and manufacture, need to be overcome. A non common but interesting research area is related to peptides with intracellular targets, which opens up new possibilities, allowing the modulation of processes occurring within the cell or interference with signaling pathways. However,...

Recombinant clathrin protein fragments form assemblies that template gold nanocrystals in an array across the latticed surface. The nanocrystals exhibit unusual anisotropic morphologies with long range ordering, both of which are dependent upon the presence of a hexahistidine tag on the clathrin heavy chain fragments.

hojatt-ol hagh hakim abolfath-e omar ibn-e ebrahim known as khayyam or khayyami, was a philosopher, mathematician, astrologer, and poet of late fifth-early sixth century a.d. for long he was famous for his scientific features, however, later on his stanzas, were introduced to the world, the west in particular, through the translations provided by the nineteenth century british poet fitzgerald. ...

tawfigh al-hakim is a contemporary egyptian playwright who is known as the father of arabic playwriting. he felt the need to search about the human character and its dimensions, so, this issue, has been the major them in his plays. through benefiting from humanistic theories in some western literary and philosophical schools, he has combined them with religious issues and eastern mythology to i...

The function of pslD, which is part of the psl operon from Pseudomonas aeruginosa, was investigated in this study. The psl operon is involved in exopolysaccharide biosynthesis and biofilm formation. An isogenic marker-free pslD deletion mutant of P. aeruginosa PAO1 which was deficient in the formation of differentiated biofilms was generated. Expression of only the pslD gene coding region resto...
