1. Isolation and functional caharacterization of chia (Salvia hispanica) proteins
Abstract The objective was to isolate and characterize the proteins of chia seeds cultivated in the Mexican southeast. The main protein fraction was glutelins (42.94%) that had the highest Water Absorption Capacity (WAbC). Prolamins had the highest Water Adsorption Capacity (WAdC) (1.83 g/g). Glutelins registered the highest Water Holding Capacity (WHC). A h

2. BACTERIAL NANOCELLULOSE BIOMEMBRANE AS A SUPPORT FOR HUMAN INSULIN AIMING AT TRANSDERMAL PERMEATION
Production of bacterial nanocellulose was pursued as a matrix system for the stabilization of human insulin. The biomembranes produced by Gluconacetobacter hansenii were washed with 2% aqueous sodium dodecylsulfate solution, rinsed with ultrapure water and immersed in 1 mol L-1 NaOH aqueous solution at 60 °C for 90 min until neutralization. For the insulin

3. POLYETHERIMIDE/POLYVINYLPYRROLIDONE HOLLOW-FIBER MEMBRANES FOR USE IN HEMODIALYSIS
Abstract In this study, polyetherimide/polyvinylpyrrolidone (PEI/PVP) hollow fiber membranes (HFMs) were synthesized by the phase inversion method. The synthesized PEI/PVP membranes were characterized by morphological analysis and transport properties (hydraulic permeability and solute rejection coefficient). Their performance in uremic solutes separation wa

5. Effects of miniemulsion operation conditions on the immobilization of BSA onto PMMA nanoparticles
Abstract Polymer nanoparticles have been widely used in many biomedical applications, constituting a major incentive for immobilization of proteins. Poly(methyl methacrylate) nanoparticles were synthesized through miniemulsion polymerizations and used as supports for bovine serum albumin immobilization. Particularly, the effects of surfactant type (anionic s

7. Proteomic analysis of the acquired enamel pellicle formed on human and bovine tooth: a study using the Bauru in situ pellicle model (BISPM)
Abstract The acquired enamel pellicle (AEP) is an organic film, bacteria-free, formed in vivo as a result of the selective adsorption of salivary proteins and glycoproteins to the solid surfaces exposed to the oral environment. Objective: This study aimed to compare the proteomic profile of AEP formed in situ on human and bovine enamel using a new intraoral

8. Extraction of matrine from Sophora flavescens Ait. and evaluation of its inhibitory effects on human nasopharyngeal carcinoma CNE-2 cells
Abstract The present study investigated the extraction and purification technology of matrine from Sophora flavescens Ait. and the inhibitory effects of matrine on human nasopharyngeal carcinoma (NPC) CNE-2 cells. The matrine was extracted from Sophora flavescens Ait. by decocting using ethanol-aqueous solution as the solvent, followed by purification using

9. Human Embryonic Stem Cell-Derived Mesenchymal Progenitor (hESCs-MP) Growth on Nanostructured Ti6Al4V Surfaces
Nanotexturing processes that focus on enhancing the bone-implant contact, such as electropolishing, have been proposed. The aim of this work was to evaluate the influence of Ti6Al4V surface morphology on human embryonic stem cell-derived mesenchymal progenitor (hESCs-MP) growth. Three surface treatments were used in this study: mechanically polished samples

10. Potential doxorubicin delivery system based on magnetic gelatin microspheres crosslinked with sugars
Abstract The preparation and characterization of magnetic microspheres based on gelatin for use in drug delivery systems are reported. Sugars were employed as crosslinking agents and type A gelatin and type B gelatin were compared to prepare microspheres by water-in-oil emulsion. The influence of gelatin and sucrose concentration, temperature and stirring s

11. Mathematical modeling of the batch adsorption of proteins on new restricted access media with poly(ethylene glycol) as a semi-permeable barrier using compact finite differences
Abstract In this work we describe a mathematical analysis of the batch adsorption process of several proteins using a new restricted access medium consisting of agarose beads grafted with poly(ethylene glycol) (PEG) as a semi-permeable barrier and immobilized metal ions or ion exchange groups as binding sites. The model was fitted to experimental data, allow

12. Extraction of hydrocolloids from Pereskia Aculeata Miller: reuse of process residue as activated carbon for the pigment-removal phase
Abstract Hydrocolloids of Pereskia aculeata Miller (OPNH) are potential ingredients in food industry as emulsifiers and stabilizers. The extraction process of OPNH requires the removal of pigments with activated carbon. Because this step is critical to the quality of the ingredient and has an impact on costs, a new activated carbon has been developed with re
