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 ...

Background: In this study, we examined a new two step induction protocol for improving the differentiation of human umbilical cord blood-derived mesenchymal stem cells into neural progenitor cells. Materials and Methods: Human umbilical cord blood-derived mesenchymal stem cells were first cultured in Dulbecco’s modified eagle medium supplemented with 10% fetal bovine serum in a humidified incu...

castor bean, peanut, soy bean and safflower protein isolates were prepared. the amino acid content of each of the protein isolates was analysed and the essential amino acid contents were compared with the fao human requirements. the results indicated that castor bean has the highest oil and the protein content of defatted meal. safflower 3148 (marand, iran) has the highest amount of essential a...

prpc conversion to prpsc isoform is the main known cause for prion diseases including crutzfeldt-jakob, gerstmann-sträussler-sheinker syndrome and fatal familial insomnia in human. the precise mechanism underling this conversion is yet to be well understood. in the present work,  using the coordinate file of prpc (available on the protein data bank) as a starting structure, separate molecular d...

expression of eukaryotic proteins in e. coli often results in their aggregation. proper folding and solubility of therapeutical proteins are the pre-requisite for their bioactivity. this is not achieved in cytoplasmic expression in e. coli because of the absence of disulfide bonds formation. a novel expression/secretion vector was constructed which exploited β-lactamase signal sequence to trans...

Background & Objectives: Anaplastic lymphoma Kinase (ALK) is a receptor tyrosine kinase involved in the genesis of several human cancers. ALK was initially identified because of its involvement in anaplastic large cell lymphoma (ALCL). ALK is believed to foster tumorigenesis following activation by autocrine and/or paracrine growth loops. Studies reveal that the presence of anti-ALK antibodies ...
