Electron transfers in photosynthesis and respiration commonly occur between protein-bound prosthetic groups that are separated by large molecular distances (often greater than 10 AÊ ). Although the electron donors and acceptors are expected to be weakly coupled, the reactions are remarkably fast and proceed with high speci®city. Tunneling timetables based on analyses of Fe/Cu to Ru electron-tra...

A high priority of the World Health Organization (WHO) is study drugs against Pseudomonas aeruginosa , which has developed antibiotic resistance. In this order, recent research analyzing biomaterials and metal oxide nanoparticles, such as chitosan (QT) TiO 2 (NT), can transport molecules with biological activity bacteria, to propose them drug carrier candidates. present work, 10 modified benzof...

To investigate the interaction and adsorption of drug and carbon nanotube on human serum albumin, three anti-cancer drugs ([Pd(phen)(R-gly)]NO3, R = methyl, propyl and amyl) with different hydrophobic tails and anticancer activities were selected. These drugs have better anti-tumor activity and less side effects than that known cis-platinum drug. Human serum albumin is also ...

The objective of this study is to design a simple, fast, sensitive and single-use electrode with the simultaneous capability of preconcentration and measuring, for application in a three-electrode voltammetry system to identify and measure the heavy metal cadmium. The design process of this sensor consists of several stages. The polyurethane foam and multi walled carbon nanotubes nanoparticles ...

mobile carrier properties of two schiff base ligands, named bis(2-hydroxypropiophenone)-1,2-propanediimine (n2o2) and bis(1'-hydroxy-2'-acetonaphthone)-2,2'-diiminodiethylamine (n3o2), dissolved in dichloromethane for the extraction of copper(ii) ions from an ammonium buffer feed phase into a nitric acid solution (receiving phase) were investigated and compared. the parameters influencing the t...

In addition to its role as an information carrier in gene expression, RNA is now recognized to carry out a broad range of biological functions, and novel activities continue to emerge on a regular basis. RNA molecules can act as catalysts in reversible phosphodiester-cleavage reactions (Fedor, 2000; Hutchins et al., 1986; Shih and Been, 2002), mediate splicing of premessenger RNA (Collins and G...

The introduction of nucleic acids into cells is one of the most valuable and frequently used tools of biological science. Transfection methods are used for a range of applications, including gene function studies, modulation of gene expression, biochemical mapping, mutational analysis and production of recombinant proteins. The transfection techniques which are commonly used today can be classi...
