BACKGROUND Clinical diagnoses were correlated with results of a Co(II)-albumin binding assay in 167 patients treated at an emergency department of a health maintenance organization. METHODS Patients were evaluated as being nonischemic or potentially ischemic through standard coronary disease indicators [creatine kinase (CK), CK-MB, cardiac troponin I, and(More)
Tryptophan 214, the only tryptophan residue in human serum albumin, is located in the physiologically important subdomain 2A ligand binding site. In the present study the fluorescence lifetime of tryptophan 214 in the following human serum albumin (HSA) mutants with substitutions in subdomain 2A were determined: K195M, K199M, F211V, R218M, R218H, R218A,(More)
Site-directed mutagenesis was used to study the role of histidine residues located in domain I in the neutral-to-basic (N-B) transition of human serum albumin (HSA). Based on a previous study of the N-B transition by means of proton NMR, the following recombinant HSA species were synthesized in the yeast species, Pichia pastoris: H9F, H9S, H39F, H39S, H67F,(More)
This paper presents classification of the related methods used in wireless channel modeling, including mathematical modeling, stochastic modeling, Ray-tracing, Ray-launching, FDTD. The comparison between the empirical models and the deterministic models helps to distinguish the application situation of each channel model. Therefore, the study will promote(More)
The protein LMO3 belongs to the LIM only (LMO) group of transcriptional regulators, which act as molecular adaptors for protein-protein interactions. However, little is known about its interactive proteins and functions. Evaluating LMO3 in a yeast two-hybrid screen, we identified the calcium- and integrin-binding protein CIB as an LMO3-binding protein,(More)
Propofol and halothane are clinically used general anaesthetics, which are transported primarily by HSA (human serum albumin) in the blood. Binding characteristics are therefore of interest for both the pharmacokinetics and pharmacodynamics of these drugs. We characterized anaesthetic-HSA interactions in solution using elution chromatography, ITC(More)
rhEPO is frequently used in clinical practice to treat anemia. However, recently rhEPO has been reported to accelerate tumor growth, progression and metastasis. Many pituitary adenoma patients, particularly those with macroprolactinomas, tend to have anemia and may need rhEPO therapy. To date, whether rhEPO has(More)
Previous studies have shown that many arachidonic acid metabolites bind to human serum albumin (HSA) and that the metabolism of these molecules is altered as a result of binding. The present study attempted to gain insights into the mechanisms by which prostaglandins bound to subdomain 2A of HSA are metabolized by catalytic processes. The breakdown of the(More)
Multiple binding sites for anaesthetics in HSA (human serum albumin) make solution studies difficult to interpret. In the present study, we expressed the wild-type HSA domain 3 (wtHSAd3), a peptide with two known anaesthetic binding sites in a yeast expression system. We also expressed a site-directed mutant of domain 3 (Y411Wd3). The stability and(More)
