Preparative chromatographic fractions of human umbilical cord hyaluronic acid (HA) of a molecular weight of 10(6) were subjected to graded oxygen-derived free radical (oxy radical) fluxes produced by: (a) the autoxidation of ferrous ions; (b) the action of xanthine oxidase (XO) on hypoxanthine (HX); and (c) by peripheral blood polymorphonuclear leucocytes that had been stimulated by phorbol myr...

We have previously shown that microtubules in nonneuronal cells form long, stable bundles after transfection with the embryonic neuronal microtubule-associated protein MAP2c. In this study, we found that treating MAP2c-transfected cells with the actin depolymerising drug cytochalasin B led to the outgrowth of microtubule-containing processes from the cell surface. This effect was specific to MA...

This study aimed to determine the effect of supplied pyrolysis oils (oils obtained from used tyres and depolymerisation plastics) on activity hydrodesulphurisation catalyst. Each oil was added at 20% weight a standard feedstock processed pilot plant reactors under set conditions commercial unit, including an activated Following catalyst stabilisation, material changed mixture with oils. The rea...

In order to improve the lignin exploitation added-value bioproducts, a mild chemical conversion route based on electrochemistry was investigated.

Purpose This paper aims to develop a novel strategy manufacture poly-lactic acid (PLA) filaments reinforced with Mg particles for fused filament fabrication of porous scaffolds biomedical applications. Design/methodology/approach The mixture PLA pellets and was extruded twice, the second time using precision extruder that produces zero porosity, constant diameter homogeneous dispersion particle...

Efficient pretreatment of lignocellulosic biomass is needed to reduce associated energy costs. Lignin-degrading bacteria ( Comamonas testosteroni, Agrobacterium sp. , Lysinibacillus sphaericus, and Paenibacillus sp.) were tested as potential pre-treatment methods for oil palm empty fruit bunches (OPEFB) enhance its methane yield during anaerobic digestion (AD). The lignocellulose fractions anal...
