We describe a general method for incorporating target ligands into the surface of biocompatible polyester poly(lactic-co-glycolic acid) (PLGA) 50/50 materials using fatty acids. Avidin-fatty acid conjugates were prepared and efficiently incorporated into PLGA. Avidin was chosen as an adaptor protein to facilitate the attachment of a variety of biotinylated ligands. We show that fatty acid prefe...

Cell differentiation on glutaraldehyde cross-linked ovalbumin scaffolds was the main focus of this research. Salt leaching and freeze drying were used to create a three-dimensional porous structure. Average pore size was 147.84 ± 40.36 μm and 111.79 ± 30.71 μm for surface and cross sectional area, respectively. Wet compressive strength and elastic modulus were 6.8 ± 3.6 kPa. Average glass trans...

Xue, School of Material and Metalurgy, Northeastern University, Shenyang, China The titanium dioxide(TiO2) was prepared by efficient decomposition of titaniumbearing blast furnace slag (TBBFS) in molten salt system. The as-prepared TiO2 were characterized by X-r...

Hyaff 11 R , a material derived from hyaluronic acid with interesting applications as a scaffold for tissue engineering, is made porous by salt leaching and mechanically tested in simple tension and confined compression. The tests revealed a different behavior in tension and compression, a feature common to other foamed materials. The difference between the behavior in tension and compression i...

In Canterbury land-use intensification, particularly irrigated dairy expansion, is occurring on stony soils. Concerns exist about the ability of these soils to sustain intensified land-use, while maintaining nutrient leaching within discharge limits. Environmental models consistently predict stony soils as having a high vulnerability to leaching under intensive land use, but there is little exp...

Blends of chitosan and synthetic aliphatic polyesters (polybutylene succinate, polybutylene succinate adipate, polycaprolactone, and polybutylene terepthalate adipate) were compounded with and without hydroxyapatite, a bioactive mineral filler known to enhance osteoconduction. The blends and composites were compression molded with two different granulometric salt sizes (63-125 microm and 250-50...

There is an increasing call for the absolute quantification of time-resolved metabolite data. However, a number of technical issues exist, such as metabolites being modified/degraded either chemically or enzymatically during the extraction process. Additionally, capillary electrophoresis mass spectrometry (CE-MS) is incompatible with high salt concentrations often used in extraction protocols. ...

Successful irrigation management of tree and vine crops to control soil salinity requires adequate leaching, which is defined as sufficient water to remove excess salts from the root zone above that required to meet crop demand. Excess salts decrease growth and yield in trees and vines and may lead to more severe effects such as leaf bum and even plant death. The salt tolerances of many crops h...

To understand the enzymatic degradation behavior of crosslinked polylactide (PLA), the preparation and enzymatic degradation of both thermoplastic (linear) and crosslinked PLAs that have pore structures with different dimensions were carried out. The porous structures of the linear PLA samples were of micro and nanoporous nature, and prepared by batch foaming with supercritical CO2 and compared...
