The development of reliable processes for the synthesis of gold nanoparticles is an important aspect of current nanotechnology research. Recently, reports are published on the extracellular as well as intracellular biosynthesis of gold nanoparticles using microorganisms. However, these methods of synthesis are rather slow. In present study, rapid and extracellular synthesis of gold nanoparticle...

glycoconjugates and their programmed changes during the course of development in the cell-surface as well as in the extracellular matrix, are known to affect cell differentiation, cellular interaction and other developmental phenomena during embryogenesis. the purpose of this study was to localize n-acetylgalactosamin as well as fucose-containing glycoconjugates in situ during thymus developmen...

conclusions we found a marked increase in the incidence of non-albicans species (48.2%) among neutropenic patients. only a few strains failed to produce extracellular enzymes. finally, in addition to fluconazole, caspofungin can be considered as the first line treatment against candida species among neutropenic patients. results a total of 110 yeast strains isolated from urine and oral cavities...

Extracellular production of metal nanoparticles by several strains of the fungus Fusarium oxysporum was carried out. It was found that aqueous silver ions when exposed to several Fusarium oxysporum strains are reduced in solution, thereby leading to the formation of silver hydrosol. The silver nanoparticles were in the range of 20-50 nm in dimensions. The reduction of the metal ions occurs by a...

the development of reliable processes for the synthesis of nanoparticles is an important aspect of nanotechnology. biologically synthesized nanoparticles could have innumerable applications in different areas such as reception, catalyzers, biolabellers, etc. in the present review, we emphasize the richness of the microbial world which encompasses a plethora of endophytic entities as an emerging...

The cell surface and extracellular matrix polysaccharide, heparan sulfate (HS) conveys chemical information to control crucial biological processes. HS chains are synthesized in a non-template driven process mainly the Golgi apparatus, involving large number of enzymes capable subtly modifying its substitution pattern, hence, interactions effects. Changes localization HS-modifying throughout we...

There is increasing evidence to suggest that extracellular matrix (ECM) components play an active role in tumor progression and are an important determinant for the growth and progression of solid tumors. Tumor cells interfere with the normal programming of ECM biosynthesis and can extensively modify the structure and composition of the matrix. In ovarian cancer alterations in the extracellular...

Our previous papers demonstrated that preeclampsia – associated accumulation of collagen and proteoglycans in the umbilical cord tissues is a result of increased biosynthesis and decreased degradation of these components. Metalloproteinases are enzymes engaged in degradation of collagen and protein cores of proteoglycans, including those which bind peptide growth factors. Western Immunoblot met...

Cartilage proteoglycans are extracellular macromolecules with complex structure, composed of a core protein onto which a variable number of glycosaminoglycan chains are attached. Their biosynthesis at the glycosaminoglycan level involves a great number of sugar transferases well-orchestrated in Golgi apparatus. Similarly, their degradation, either extracellular or intracellular in lysosomes, in...
