To assess the feasibility of generating functional transgenes directly via homologous recombination between microinjected DNA fragments, three overlapping genomic DNA fragments, together constituting the human serum albumin (hSA) gene, were coinjected into murine zygotes. The resulting transgenic mice were analyzed for structure and expression of the transgene. All transgenic mice carried recom...

advanced glycation end-products (ages) are formed by non-enzymatic reaction between reducing sugar and protein. ages play important roles in pathogenesis of diabetic, aging complications, endothelial dysfunction and neurological diseases such as the alzheimer’s disease. therefore compounds that prevent the glycation reaction are purported to have therapeutic effect on patients with diabetes and...

Different studies reported the presence of oxidized (carbonylated) albumin in the extravascular pool, but not in the intravascular one of cigarette smokers. In this study we attempted to explain this apparent discrepancy exposing human serum albumin (HSA) to aqueous cigarette smoke extract (CSE). CSE induces HSA carbonylation and oxidation of the HSA Cys34 sulfhydryl group. An antioxidant actio...

The combinatorial fluorescent dapoxyl dye library was prepared by both solution- and solid-phase synthesis, generating 80 unique dapoxyl derivatives. A fluorescence-based screening toward human serum albumin (HSA) found one highly sensitive HSA binder ( A41-S) with over 55-fold intensity change. Displacement assay showed the selective binding of A41-S to the site I of HSA, addressing its potent...

Technetium-99m human serum albumin ((99m)Tc-HSA) is an important radiopharmaceutical required in nuclear medicine studies. However, the risk of transfusion-transmitted infection remains a major safety concern. Autopreparation of serum component acquired from patient provides a "personal-exclusive" source for radiolabeling. This paper is to evaluate the practicality of on-site elusion and subseq...

Human serum albumin (HSA) is the most abundant plasma protein in the human body. HSA plays an important role in drug transport and metabolism. This protein has a high affinity to a very wide range of materials, including metals such as Cu2+ and Zn2+, fatty acids, amino acids and metabolites such as bilirubin and many drug compounds. In this study, we investigated the effects of co-amoxiclav, as...

(mean HSA level 3.3 g/ 100 ml, normal with 12 I-labeled human serum albumin (HSA) in five patients with monoclonal gammopathy; three with Waldenstr#{246}m’s macroglobulinemia (one also had a monoclonal protein) and one patient each with yG multiple myeloma and yG benign gammopathy. Several abnormalities in HSA metabolism occurred in different combinations in different patients and no single con...

Aflatoxins are widely spread mycotoxins produced mainly by Aspergillus species. Consumption of aflatoxin-contaminated foods and drinks causes serious health risks for people worldwide. It is well-known that the reactive epoxide metabolite of aflatoxin B1 (AFB1) forms covalent adducts with serum albumin. However, non-covalent interactions of aflatoxins with human serum albumin (HSA) are poorly c...

background: protein aggregation is one of the important, common and troubling problems in biotechnology, pharmaceutical industries and amyloid-related disorders. methods: in the present study, the inhibitory effects of some carbohydrates (alginate, β-cyclodextrin and trehalose) on the formation of nano-globular aggregates from normal (hsa) and glycated (ghsa) human serum albumin were studied; w...

studying the interaction of pharmaceutical ionic liquids with human serum albumin (hsa) can help investigating whether or not ionic liquid formation can enhance pharmacological profile of the discrete ingredients. in this respect, in the present work, the interactions of benzalkonium ibuprofenate, as a well-known active pharmaceutical ionic liquid, benzalkonium chloride, and also sodium ibuprof...
