Fingerprint signatures of circularly polarized luminescence (CPL) are observed from Staphylococcus aureus nuclease (SNase), bovine serum albumin (BSA), and insulin (Ins) labeled with europium(III) complexes containing a β-diketonate ligand, where SNase shows a virtually opposite CPL sign compared to those of BSA and Ins.

Inorganic nanomaterials that mimic enzymes are fascinating as they potentially have improved properties relative to native enzymes, such as greater resistance to extremes of pH and temperature and lower sensitivity to proteases. Although many artificial enzymes have been investigated, searching for highly-efficient and stable catalysts is still of great interest. In this paper, we first demonst...

Fluorescent x-ray interference patterns have been observed from monolayers of both a metal-containing protein (ferritin) and a nonmetal-containing protein [bovine serum albumin (BSA)] bound on a gold substrate. These interference patterns have been used to determine structure data. The nonmetal-containing protein was first reacted with metal ions by means of a chelate compound to place the nece...

OBJECTIVE Many clinicians limit chemotherapy doses based on a maximum body surface area (BSA) of 2m(2). We sought to determine how chemotherapy-related toxicities compared between groups of patients that varied with respect to BSA. We hypothesized that obese patients receiving weight-based (WB) dosing would not have significantly higher chemotherapy-related toxicities than control groups. MET...

To determine if the number of targeting signals affects the transport of proteins into the nucleus, Xenopus oocytes were injected with colloidal gold particles, ranging in diameter from 20 to 280 A, that were coated with BSA cross-linked with synthetic peptides containing the SV-40 large T-antigen nuclear transport signal. Three BSA conjugate preparations were used; they had an average of 5, 8,...
