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...

INTRODUCTION This study investigated the inhibition of the antimicrobial activity of sodium hypochlorite (NaOCl) by bovine serum albumin (BSA). The killing of Enterococcus faecalis, Candida albicans, Staphylococcus epidermidis, and Escherichia coli by NaOCl in concentrations from 2% to 0.03% was measured in the presence of BSA in concentrations between 6.7% and 0.1%. METHODS NaOCl, BSA, and m...

to be avoided. Berthed and Rey (1) have also reported enormous crossreactivityof hydrocortisonehemisuccinate in the “Rianen” RIA kit for cortisol determination. An issue of Clinical Chemistry (1983;29:890-953) reports the commercial availability of(then)more than 27 cortisol RIA kits.Methodologically, these kits were divided into three groups according to the different antibodies used: antibodi...

For patients with high body surface areas (BSA), differing chemotherapy dosing strategies have been utilized in attempts to reduce toxicity. In a retrospective evaluation, we compared the effects of chemotherapy dosing in acute myeloid leukemia patients with high BSA (>2m(2)) who received capped doses (n=12) to those who received uncapped doses (n=24), and to patients with BSA≤2m(2) (n=42). The...

Biodegradable hollow capsules filled with fluorescently labelled bovine serum albumin (BSA) as a model drug were prepared via layer-by-layer (LbL) self-assembly of type-I collagen (COL) and hyaluronic acid (HA) using calcium carbonate micro-particles and co-precipitation method. Capsules loaded with fluorescein isothiocyanate (FITC)-BSA, tetramethylrhodamin isothiocyanate (TRITC)-BSA or Alex-Fl...

In the present study, the accumulation of apolipoproteins (apo) A-I, B, and E in culture medium was measured after 0, 3, 6, 12, and 24 h of incubation with 150 microM docosahexaenoic acid complexed to 75 microM bovine serum albumin (BSA-22:6), either in the presence or absence of 50 micrograms/ml cholesterol and 4 micrograms/ml 25-hydroxycholesterol (C/25-OH). HepG2 cells incubated with BSA + C...

The reaction between reducing sugars and protein free amines, known as the Maillar reaction results in the formation of advanced glycation endproducts (AGEs). AGE modification changes the structure of proteins to amyloid cross-beta structure. These protein structures can activate receptors known as RAGE on glial cells (microglia and astrocytes), and induce the expression of inducible nitric oxi...

Terahertz spectroscopy was used to study the absorption of bovine serum albumin (BSA) in water. The Diamond Light Source operating in a low alpha mode generated coherent synchrotron radiation that covered a useable spectral bandwidth of 0.3-3.3 THz (10-110 cm(-1)). As the BSA concentration was raised, there was a nonlinear change in absorption inconsistent with Beer's law. At low BSA concentrat...

Optimal conditions were determined for photophosphorylation and reduction in mature chloroplasts from Phaseolus vulgaris var. Red Kidney. Bovine serum albumin (BSA) at 1 mg/ml and various sulfhydryl reagents (0.1-0.5 mm) greatly enhanced cyclic and noncyclic phosphorylation, but had little effect on photoreduction. BSA and reduced glutathione also stimulated cyclic phosphorylation in spinach ch...
