1. 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

2. 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

3. Adsorption of BSA (Bovine Serum Albuminum) and lysozyme on poly(vinyl acetate) particles
Abstract Poly(vinyl acetate) (PVAc) particles find many uses in the biomedical field, including the use as particle embolizers. Particularly, embolizing particles can combine physical and chemical effects when they are doped with pharmaceuticals. For this reason, the adsorption of bovine serum albuminum (BSA) and lysozyme (used as model biomolecules) on PVAc

4. Filmes ultrafinos de ésteres de celulose: preparo, caracterização e imobilização de proteínas
In this study cellulose acetate butyrate (CAB) and carboxymehtylcellulose acetate butyrate (CMCAB) films adsorbed onto silicon wafers were characterized by means of ellipsometry, atomic force microscopy (AFM), sum frequency generation spectroscopy (SFG) and contact angle measurements. The adsorption behavior of lysozyme (LIS) or bovine serum albumin (BSA) on

5. Characterization and application of thin film of carboxymehtylcellulose acetate butyrate / Caracterização e aplicação de filmes finos de acetato butirato carboximetil celulose
The effect of ethyl acetate and acetone on the solution behavior of cellulose acetate butyrate (CAB) and carboxymehtylcellulose acetate butyrate (CMCAB) and on the characteristics of films obtained either by spin coating or adsorption was investigated. Viscosity and small angle X-ray scattering (SAXS) measurements showed that ethyl acetate is a better solven

6. Cromatografia negativa em Sepharose-TREN como tecnica de purificação de proteinas adicionadas artificialmente a extrato de soja / Negative chromatography on Sepharose-TREN as a technique of proteins purification artificially added to soybean extract
In recent years, plants have been studied as bioreactors for the production of recombinant proteins with industrial and pharmaceutical interest. When compared to other expression systems, plants have several advantages, such as the possibility of posttranlationals modification, low production cost, low risk of contamination by human pathogens, and the accumu

7. Separação da lisozima, conalbumina e ovalbumina presentes na clara do ovo: aspectos tecnológicos e termodinâmicos / Separation of lysozyme, conalbumin and ovalbumin from the egg white: technological and thermodynamic aspects
Neste trabalho, estudou-se a integração dos processos de cromatografia de adsorção em leito expandido (ALE) e extração líquido-líquido por sistemas aquosos bifásicos (SAB) para a separação e purificação das proteínas da clara do ovo (ovalbumina, conalbumina e lisozima). A ALE foi empregada para a separação de duas frações protéicas da clar

8. Cellulose acetate propionate coated titanium: characterization and biotechnological application
Surfaces of pure titanium and Ti coated with cellulose acetate propionate (CAP) have been characterized by means of scanning electron microscopy X ray coupled with elemental microanalysis (SEM-EDS), ellipsometry, atomic force microscopy (AFM) and contact angle measurements. Coating Ti surfaces with CAP ultrathin films reduced original surface roughness. Surf

9. Characterization of chemically modified chitosan microspheres as adsorbents using standard Proteins (bovine serum albumin and lysozyme)
Chitosan microspheres with a mean size of 140 ± 119 µm were produced by the spray and coagulation methods. The microspheres were chemically modified using the following routes: a) crosslinking with glutaraldehyde b) crosslinking with epychlorohydrin and c) acetylation. For investigation of their ability as adsorbents, the following standard proteins were c

10. Production and characterization of natural and chemically modified chitosan microspheres and its use in the adsorption of BSA and lysozyme proteins / Produção e caracterização de microesferas de quitosana natural e modificada quimicamente e o seu uso na adsorção das proteinas BSA e lisozima
Neste trabalho foram produzidas microesferas de quitosana com tamanho controlado e porosidade influenciada pela técnica de atomização e coagulação. As condições de produção foram definidas pelo planejamento de experimentos. As microesferas obtidas foram modificadas quimicamente com anidrido acético, epicloridrina e glutaraldeído com objetivos de m

11. Scanning electron microscopy study of protein immobilized on SIO2 Sol-gel surfaces
Uniform attachment of enzymes to solid surfaces is essential in the development of bio and optical sensor devices. Immobilization by adsorption according to hydrophilic or hydrophobic nature is dependent on the charges and defects of the support surfaces. Sol-gel SiO2 densified glass surfaces, frequently used as supports for protein immobilization, are evalu

12. PURIFICATION OF alfa-LACTALBUMIN USING PEPTIDES AS AFFINITY CHROMATOGRAPHY LIGANDS
A method for the purification of alfa-lactalbumin from whey protein isolate solutions using a hexapeptide ligand has been developed. The peptide WHWRKR was isolated from a peptide library generated by combinatorial chemistry, and displays affinity to alfa-lactalbumin. Other proteins from whey protein isolate bound nonspecifically to the resin used. Different
