The adsorption behavior of dipalmitoylphosphatidylcholine (DPPC), which is the major component of lung surfactant, at the air/aqueous interface and the competitive adsorption with bovine serum albumin (BSA) were studied with tensiometry, infrared reflection absorption spectroscopy (IRRAS), and ellipsometry. Dynamic surface tensions lower than 1 mN/m were observed for DPPC dispersions, with most...

OBJECTIVES We studied the antithrombotic effect of coating glass, collagen and metal stent surfaces with bovine serum albumin (BSA) covalently modified to carry S-NO functional groups denoted (pS-NO-BSA). METHODS Video-enhanced light microscopy was used to visualize canine blood platelet adhesion and aggregation in a parallel plate glass chamber. Platelet adhesion was observed for 60 min on g...

Two phenylethanoid glycosides, acteoside and forsythoside B, were first isolated from the traditional Chinese herb Callicarpa peii H.T. Chang. The interaction between the two phenylethanoid glycosides and bovine serum albumin (BSA) was investigated by fluorescence, UV-vis absorbance and circular dichroism (CD). The results showed that the quenching mechanism in the drug-BSA binary systems was a...

The effect of gender and degree of obesity on the size indicators V, used to normalize urea clearance (Kt/Vur), and body surface area (BSA), used to normalize creatinine clearance (Ccr), in peritoneal dialysis was studied by: (1) mathematical comparison of the formulae used to estimate V (Watson and Hume) with the Dubois formula used to estimate BSA in peritoneal dialysis; and (2) comparison of...

We examined the role of antigenic charge on the deposition of immune complexes (IC) in murine gloerulia Acute serum sickens nephritis was induced by injecting chemically modified cationic bovine serum albumin (cationic BSA). Controls were immunized with unmodified native BSA (native BSA), All mice were given a primary intraperitoneal immunization with 500 pg of the respective antigens plus Freu...

Electrospinning of the globular protein, bovine serum albumin (BSA), was optimized to obtain proteinous fibers suitable as biosensors. It was shown that the as-spun protein preserves its native form, whereas solubility of the cross-linked in the ambient conditions BSA nanofibers evidently decreases. Insoluble BSA fibers can be easily modified to be used as two-dimensional biosensors. Here, we s...

This study investigated the interaction between eupatorin and bovine serum albumin (BSA) using ultraviolet-visible (UV-vis) absorption, fluorescence, synchronous fluorescence, circular dichroism (CD) spectroscopies, and molecular modeling at pH 7.4. Results of UV-vis and fluorescence spectroscopies illustrated that BSA fluorescence was quenched by eupatorin via a static quenching mechanism. The...

The adsorption and conformation of bovine serum albumin (BSA) on gold nanoparticles (AuNPs) were interrogated both qualitatively and quantitatively via complementary physicochemical characterization methods. Dynamic light scattering (DLS), asymmetric-flow field flow fractionation (AFFF), fluorescence spectrometry, and attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectrosco...
