The efficient acentric L-ornithine monohydrochloride (LOMHCl), which belongs to the trait of semiorganic category and depicts nonlinear optical characteristics, was grown-up by the process of slow evaporation. The crystal structure and crystallinity of LOMHCl was established by the process of si...

It is well established that contact order and folding rates are correlated for small proteins. The folding rates of stefins A and B differ by nearly two orders of magnitude despite sharing an identical native fold and hence contact order. We break down the determinants of this behavior and demon...

Recombinant human cysteine protease inhibitor, stefin A, was expressed in both Escherichia coli and BS-C-1 monkey kidney cells utilizing pET and recombinant vaccinia virus systems, respectively. The expressed protein was purified and analyzed by SDS–PAGE and Western blot analysis utilizing a po...

Purpose: The aim of this study was to test the hypothesis about the protective role of high stefin A and stefin B concentrations in operable carcinoma of the head and neck.Methods and Materials: Stefins A and B concentrations were measured in tissue cytosols of nontumorous mucosa and primary tum...

Proteolytic activity in the tumor microenvironment is one of the key elements supporting tumor development and metastasis. One of the key families of proteases that are overexpressed in various types of cancer and implicated in different stages of tumor progression are cysteine cathepsins. Among...

A series of several compositions of YBa2Cu3−xVxO7 were prepared by conventional solid state reaction. The influence of the vanadium on the microstructure of YBa2Cu3O7 was investigated by X-ray diffraction and electron dispersion spectroscopy in terms of the cell parameter variation and the prese...

Yttrium barium copper oxide ceramics with transition temperatures of up to 98K and small transition widths have been produced by conventional mixed oxide and solution routes. The use of dispersants has been shown to give considerable improvements in powder characteristics and ceramic densities. ...

YBCO + BaTiO3 composite thin film is synthesized by pulsed laser deposition. Fluctuations on the electrical conductivity were investigated for zero fields. The logarithmic plots of excess conductivity and reduced temperature reveals two distinct regions namely mean field region and short wave fl...

The double reductive amination of l-arabino-hexos-5-ulose with benzhydrylamine and NaBH3CN takes place in a diastereospecific manner giving in moderate chemical yield (36 %) the galactosidase inhibitor 1-deoxy-d-galactostatin. The aminocyclization of 2,6-di-O-benzyl-l-arabino-hexos-5-ulose is mo...

In bull spermatozoa, extracellular Ca2+-dependent full-type hyperactivation, which is characterized by the asymmetrical beating in whole parts of the middle/principal pieces, is suppressed by calyculin A-sensitive protein phosphatases. The aim of this study was to identify isoforms of these prot...

Biologically active photoaffinity labeled analogues of taxol (6, 8 and 9) have been synthesized utilizing (3R,4S)-3-hydroxy-4-phenyl-2-azetidinones, produced via the ester enolate-imine cyclocondensation reaction, and the diterpene baccatin III (2). Photoaffinity label 8 proved to be the most ac...
