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 antibod...

background :according to numerous studies, fms-like tyrosine kinase 3, internal tandem duplication, and the d835 mutation are associated with a poor prognostic clinical outcome in acute myeloid leukemia patients. detection of the fms-like tyrosine kinase 3 mutation in patients who present with normal karyotype acute myeloid leukemia helps in both the understanding of the disease and the treatme...

A method is described for the detection of protein tyrosine phosphatase activity in sodium dodecyl sulfate-polyacrylamide gels. A radiolabeled substrate, 32P-labeled poly(glutamic acid-tyrosine) (random copolymer) is incorporated into gels prior to polymerization. Following electrophoresis, the sodium dodecyl sulfate is removed; the proteins are fully denatured by soaking gels in 6 M guanidine ...

Ferulic acid (FA), a bio-based resource found in fruits and vegetables, was coupled with a hydroxyl-amino acid to generate a new class of monomers to afford poly(carbonate-amide)s with potential to degrade into natural products. l-Serine was first selected as the hydroxyl-amino partner for FA, from which the activated p-nitrophenyl carbonate monomer was synthesized. Unfortunately, polymerizatio...

Many polymers and composites have been used to prepare active wound dressings. These materials have typically exhibited potentially toxic burst release of the drugs within the first few hours followed by a much slower, potentially ineffective drug release rate thereafter. Many of these materials also degraded to produce inflammatory and cytotoxic products. To overcome these limitations, composi...

There are many commercial antibodies with little information provided by their suppliers as to their reliability. Accordingly, commercial antibodies require proper validation before being used in scientific research. In this study, we validated several commercial antibodies, including anti-CSPα, SNAP25, tyrosine hydroxylase, ubiquitin, cleaved caspase 3, and pSer PKC motif. Anti-CSPα, SNAP25, a...

A method which uses cyanogen bromide for the quantitative conversion of 4-thiouridine to uridine has been developed. The general nature and the specificity of this reaction has been studied with thiouridine residues present in a hexanucleotide isolated from enzymic digests of Escherichia coli tyrosine transfer ribonucleic acid (tRNA), and also with those present in intact E. coli tyrosine and f...

Current methods for screening cell-material interactions typically utilize a two-dimensional (2D) culture format where cells are cultured on flat surfaces. However, there is a need for combinatorial and high-throughput screening methods to systematically screen cell-biomaterial interactions in three-dimensional (3D) tissue scaffolds for tissue engineering. Previously, we developed a two-syringe...

A mutation in Saccharomyces cerevisiae, designated mia, is responsible for the production of isoaccepting tRNA molecules with reduced extents of nucleoside modifications. The mia isoacceptors of tRNAPhe and one of the mutant isoacceptors of tRNATyr were highly purified for nucleoside composition analyses. The data indicate that the mutant isoacceptors are lacking some of the dihydrouridine moie...
