The aim of this study is to investigate the biomimetic mineralization on a cellulose-based porous matrix with an improved biological profile. cellulose was precalcified using three methods: (i) samples were treated solution calcium chloride and diammonium hydrogen phosphate; (ii) carboxymethylated stored in saturated hydroxide solution; (iii) mixed silicate order introduce silanol groups combine them ions. All methods resulted surfaces after immersion simulated body fluid solution. Over...
Cellulose scaffolds containing nano- or micro-hydroxyapatite (nHA μHA) were prepared by the regeneration of cellulose from its acetylated derivative and mechanical immobilization inorganic particles, followed freeze-drying. Microtomographic (micro-computed tomography) evaluation revealed that both presented a highly interconnected porous structure, with mean pore diameter 490 ± 94 540 132 μm for cellulose/nHA cellulose/μHA, respectively. In vitro in vivo characterizations developed...
Hydroxylation of L-tyrosine to 3,4-dihydroxyphenylalanine (L-DOPA) by immobilized tyrosinase in the presence ascorbic acid (AH2), which reduces DOPA-quinone L-DOPA, is characterized low reaction yields that are mainly caused suicide inactivation L-DOPA and AH2. The main aim this work was compare processes with native identify conditions limit produce substrate conversions above 50% using HPLC analysis. It shown does not suffer from partitioning diffusion effects, allowing a direct comparison...
Recently, usage of marine-derived materials in biomedical field has come into prominence due to their promising characteristics such as biocompatibility, low immunogenicity and wide accessibility. Among these marine sources, cuttlebone been used a valuable component with its trace elemental composition traditional medicine. Recent studies have focused on the use bioactive agent for tissue engineering applications. In this study, hydroxyapatite particles were obtained by hydrothermal...
In bioprocesses lipases are typically used in immobilized form, irrespective of type reaction systems, to ensure an even distribution catalysts water restricted media and/or facilitate separation and reuse. these studies we report on the selection appropriate enzyme-carrier preparation for hydrolysis aqueous biphasic systems transesterification organic solvent. For this Candida rugosa lipase was bound by adsorption or covalent attachment onto various carriers give 24 preparations. Selection...
Abstract The hydrophobic packing for preparative low pressure interaction chromatography (HIC) on the new granulated cellulose matrix Granocel were prepared by alkylation with phenyl glycidyl ether in presence of sodium hydroxide. ligand concentration up to 600 μmol/g was achieved high reproducibility. relative amount eluted model protein at fixed set conditions used as a criterion evaluation hydrophobicity adsorbents. found depend accessible, rather than total, coupled well nature matrix....
