Abstract (sommario):

Early introduction of cow's-milk-based infant formulas, in particular the ABBOS epitope of bovine serum albumin (BSA), has been implicated as an autoimmune trigger in the pathogenesis of insulin dependent diabetes mellitus (IDDM). A direct enzyme-linked immunosorbant assay (ELISA), using polyclonal anti-BSA antibodies, was developed to determine the BSA content of cow's milk and 15 infant formulas. Powdered high-whey (60%) formulas averaged 41 mg BSA/100 ml; 2% milk contained 52 mg BSA/100 ml; and the high-casein formulas averaged 13 mg/100 ml. BSA content of powdered polymeric formulas and co

Abstract (sommario):

Glycation of whey proteins results in food-grade composites with modified physicochemical properties. Here, the reaction between glucose and bovine serum albumin (BSA) is promoted under wet-heating conditions. The glycated protein is characterized in depth and compared to the native counterpart and the impact of glycation on properties like net surface charge, particle size and surface hydrophobicity are observed. Conjugation with glucose reduced the surface hydrophobicity of BSA but the interactions between albumin and curcumin became stronger, which contradicts the direct relationship betwee

Dissertação de Mestrado Integrado em Medicina Veterinária<br>Chronic Enteropathy (CE) is a complex disease that is thought to result from an overstated immune response against alimentary and microbiota antigens in susceptible animals. The amplified inflammation of the mucosa promoted by the increased and abnormal gut permeability in sick patients known as ‘leaky gut’, allows the antigens to pass through the systemic circulation, culminating in an unbalanced excessive immune response that is followed by the production of specific Immunoglobulins (Ig).

Abstract (sommario):

Bioactive peptides represent an important source of health promoting food. Therefore, the objective of this study was to identify the in vitro antioxidant and ACE inhibitory peptides derived from bovine serum albumin (BSA) and to characterise them after further purification. To achieve this objective, BSA was hydrolyzed with pepsin enzyme, fractionated by ultrafiltration using a 10 kDa molecular weight cut off membrane, and purified by gel filtration chromatography prior to characterisation. The total antioxidant activity was evaluated in a linoleic acid model system using the ferric thiocyana

Abstract (sommario):

This thesis is concerned with the adsorption of bovine serum albumin to polyethylene tubing. A method using radioiodinated protein was developed to measure the surface concentration taking into account the dilution effect for miscible displacement in a capillary. A steady-state surface concentration was established within 2 hours. Adsorption did not depend on the ratio of radiolabelled to unlabel led protein. The adsorption isotherm was Langmuir-like with a plateau concentration of approximately 0.2 μg/cm². Two methods were used to calculate the surface concentration in the desorption study.

Abstract (sommario):

CoCrMo is one of the most widely used materials for prostheses. CoCrMo has high wear resistance, excellent corrosion resistance, and good biocompatibility. High corrosion resistance is ascribed to the formation of an oxide layer. However, the oxide layer does not remain intact in the corrosive body environment that contains oxygen, chloride, proteins, and carbohydrates. The presence of organic and inorganic species changes the oxide layer of CoCrMo to facilitate corrosion. Corrosion is one of the main issues that leads to revision surgery. CoCrMo has been used extensively in synovial joints

Abstract (sommario):

碩士<br>國立交通大學<br>光電系統研究所<br>105<br>In this study, it is the first time that blue phase liquid crystals are used for biomedical detection. Because of the Bragg reflection caused by the blue phase liquid crystals, we can observe the change of the blue phase reflection peak from different BSA concentration sample and realize the quantification in liquid crystal biomedical detection. In the experiment, there are two different mixture being investigated and the effects of detection from each mixture are also different. In the first part result of the E7 doped with chiral R5011, the uniform blue phas

碩士<br>中原大學<br>物理研究所<br>100<br>In this thesis, we have two parts to present. In the first one, we investigated luminescence mechanism of Bovine Serum Albumin-coated gold nanoclusters by photoluminescence (PL), and time-resolved photoluminescence (TRPL) experiments at different temperatures. In the carrier recombination process, we observed the confinement effect in our sample. By measuring the TRPL at low temperatures, the activation energy at different temperatures can be fitted. We also obtain localized depth of carriers in our sample, suggesting the luminescence mechanism of AuNCs@BSA. In th

Abstract (sommario):

Bovine Serum Albumin (BSA) in water and PBS get affected by the introduction of different ionic liquids. The impact of the model ionic liquids, i.e., 1-ethyl-3-methylimidazolium sulfate, 1-ethyl-3-methylimidazolium chloride, and 1-butyl-3-methylimidazolium chloride, on the tryptophan environment (Trp-environment) was determined by using fluorescence technique. The effect of different aprotic ionic liquids with the variations in cations and anions is very much significant. The presence of ionic liquids alters the Trp environment present in BSA, i.e., presence of hydrophobic and longer alkyl cha

Abstract (sommario):

Determination of whether ion specific potassium halides binding with BSA occurred within the experimental conditions was the aim of the study. Ultrasound velocity measurements using a Resoscan system and density measurements using a DMA 5000M density meter were made to analyse BSA conformation in the presence of potassium salts of the Hofmeister series. It was found that the density and the adiabatic compressibility of BSA-potassium halide mixed aqueous solutions cannot be predicted from the density and the adiabatic compressibility of potassium halide solutions and that of BSA solutions.

The compressive measurements and thermodynamic equilibrium for chain elasticity and water-polymer mixing results indicate that the effective crosslinking density (ve) increase with increasing the degrees of substitutions and decreasing the water contents of gels. The stress-strain data of hydrogels fitted with the slip-link model indicate that there are significant disentanglements in the network, which is increased with w

碩士<br>國立清華大學<br>核子工程與科學研究所<br>98<br>Abstract Bovine serum albumin (BSA), a highly complex protein, plays important functions in immunology analysis and food science. In the denaturation study of proteins, heat treatments are frequently required for a variety of purposes and they can change the physical, chemical, biological and functional properties of proteins. Therefore, during thermal processing to understand, monitor, and control protein changes, particularly unfolding and refolding are important. There are many methods to detect the structures of protein, such as electrophoresis, X-ray d

MALDI-TOF and RP-HPLC showed that modification of carboxyl groups caused an increase in molecular weight and hydrophilicity of SEM-BSA and SEM-OVA compared with those of BSA and OVA. CD spectra measurement revealed that modification of carboxyl groups caused a change in the secondary structure of BSA and OVA. SEM-BSA exhibited a growth inhibition on E. coli and S. aureus, while SEM-OVA onl

Abstract (sommario):

Manufactured oxide nanoparticles (NPs) have large production and widespread applications, which will inevitably enter the environment. NPs can interact with proteins in living beings due to the fact that NPs can transport into blood or across cell membranes into cells. Conformational change of protein molecules after sorption on oxide NPs has been reported. Therefore, it is important to understand the adsorption mechanism of protein onto oxide NPs surfaces. Although few works have reported protein adsorption behaviors, a general systematic comparison of the effects of particle size and surface

Abstract (sommario):

Serum albumin is the most abundant protein in blood plasma. Many drugs, including anticoagulants, tranquilizers and general anesthetics are transported in the blood while bound to albumin. Coumarins constitute an imported group of natural products that show high binding affinity towards serum albumins. Binding of coumarin-1 (7-N,N-diethylamino-4- methylcoumarin) to bovine serum albumin (BSA) results in seven fold enhancement in its fluorescence intensity, 20 nm blue shift in emission maximum and ten fold increase in fluorescence anisotropy and around four fold increase in the fluorescence l
