neuroserpin, a member of the serine proteinase inhibitor (serpin) superfamily, is known to be a neuroprotective factor in the focal ischemic stroke followed by reducing the microglial activation. neuroserpin is a protein rich of methionine residues that can scavenge the free radical species which may increase its neuroprotective effect. on the other hand, the oxidative modifications of the amin...

Hydrophobicity properties of graphite and green synthesized graphene (gsG) from exfoliated graphite/GO towards polymer membrane characteristic and properties at different weight percentage concentrations (1, 2, 3, 4 and 5 wt. %) were investigated. PSf/graphite and PSf/gsG membranes were characterized in term of hydrophobicity, surface bonding, surface roughness and porosity. FTIR peaks revealed...

this study was conducted to investigate the effects of infrared processing of barley for 60, 90, 120 and 150 seconds (s) on protein hydrophobicity, in vitro protein digestibility, degradation characteristics of protein and starch and its feeding effect on ruminal ph of sheep. the surface hydrophobicity of protein increased (p

The influence of microwave treatment on the surface roughness, hydrophobicity, and chemical composition of galena was studied. The pure galena specimens and purified galena concentrate were used in this work. A conventional multi-modal oven (with a frequency of 2.45 GHz and a maximum power of 900 W) was used to conduct the experiments. The results obtained from the atomic-force microscopy analy...

BACKGROUND Mucosal surface hydrophobicity is a key factor of the gastric acid defence barrier. In the colon, surface hydrophobicity is high but its biological function remains unexplored. AIMS To investigate the functional changes of the barrier due to removal of the surface active phospholipid layer by a detergent, or to reinforcement of the surface active phospholipid by local application o...

The cell-surface charge and cell-surface hydrophobicity of 10 strains of Azospirillum spp. were evaluated by the aqueous, two-polymer phase partitioning assay. Azospirillum spp. had moderate cell-surface hydrophobicity and charge, lower than known values for human pathogens. The hydrophobicity and charge values were higher in solid than in liquid media. A general pattern of modifying hydrophobi...

The surface net hydrophobicity and local hydrophobicity of green fluorescent protein was evaluated by using the aqueous two-phase partitioning method. The surface net hydrophobicity of GFP allowed it to be classified as a hydrophobic protein although the local hydrophobicity was low. The local hydrophobicity of the GFP was increased by a pH shift to acidic conditions and was maximal at pH 4. Th...
