Molecular layer deposition (MLD) was used to coat micron-sized protein particles in a fluidized bed reactor. Our results show that the dissolution rate of particles coated via MLD rapidly decreases with the increase in number of coating cycles, while the uncoated particles dissolve instantaneously.

We have carried out the fabrication of several gold-patterned test array structures for studies of in vitro recrystallization using 2-dimensional surface-layer (“S-layer”) proteins. These test structures, patterned via e-beam lithography exposure of a poly(methylmethacrylate (PMMA) resist layer on silicon, are comprised of square features 25-300 nm in size and spaced 2-10 μm apart. Physical vap...

It is a critical challenge to develop automated methods for fast and accurately determining the structures of proteins because of the increasingly widening gap between the number of sequence-known proteins and that of structure-known proteins in the post-genomic age. The knowledge of protein structural class can provide useful information towards the determination of protein structure. Thus, it...

The effect of starvation on whole-body protein synthesis and on the contribution of protein synthesis to basal metabolic rate was investigated in young chickens (Expt 1). Strain differences between layer and broiler chickens in whole-body protein synthesis and degradation rates were examined when the birds were starved (Expt 2). In Expt 1, 15-d-old White Leghorn male chickens were used, while i...

The surface properties of aqueous dispersions worm-like fibril aggregates bovine serum albumin (BSA) differ from those the adsorption layers native protein. BSA fibrils are characterized by slower changes tension and dynamic elasticity also have different steady-state values properties. fourfold compression layer leads to noticeably higher pressures than a compressed protein, indicating formati...

A chimera gene consisting of the ompF promoter, the coding regions for the signal peptide and the NH2-terminal 11 amino acid residues of outer membrane OmpF protein, and the coding region for the major outer membrane lipoprotein devoid of the NH2-terminal 7 amino acid residues was constructed. Escherichia coli carrying the cloned chimera gene produced a hybrid protein with the predicted chemica...

Besides the pinpointing of individual disease-related genes, associating protein complexes to human inherited diseases is also of great importance, because a biological function usually arises from the cooperative behaviour of multiple proteins in a protein complex. Moreover, knowledge about disease-related protein complexes could also enhance the inference of disease genes and pathogenic genet...

background: keratocystic odontogenic tumor (kcot) is a developmental odontogenic cyst on which various investigations have been focused due to its biological activities, high tendency to recur and different growth mechanisms in comparison with other cystic lesions. previous studies have shown different biological and proliferative activities for the lining epithelium of kcot. the aim of this st...

Histochemical studies performed on livers of the bluegill, Lepomis macrochirus, containing the larval cestode, Proteocephalus sp., indicated that the cellular capsule surrounding the parasite was composed of glycogen, basic protein with large concentrations of protein-bound amino groups, and tyrosine. An amorphous layer between the capsule and parasite gave positive reactions for mucoproteins, ...
