OBJECTIVE To demonstrate the binding and inactivation action of a superabsorbent dressing on proteolytic enzymes MMP-2, MMP-9 and collagenase using an established methodology. METHOD An in vitro assay of MMP binding and collagenase inactivation has been conducted using the superabsorbent wound dressing (Eclypse; Advancis Medical UK). Dressings in this category, and other absorbents, have been...

Incorporating superabsorbent polymer (SAP), which has the abilities of absorption and desorption in concrete can achieve the effect of internal curing. The influences of the volume, particle size and ways of entrained water of SAP on the workability, compressive strength, shrinkage, carbonation resistance and chloride penetration resistance of concrete were analyzed through the macroscopic and ...

Desertification is currently a major concern, and vast regions have already been devastated in the arid zones of many countries. Combined application of cyanobacteria with soil fixing chemicals is a novel method of restoring desertified areas. Three cyanobacteria, Nostoc sp. Vaucher ex Bornet & Flahault, Phormidium sp. Kützing ex Gomont and Scytonema arcangeli Bornet ex Flahault were isolated a...
