The renal glomerulus forms a selective filtration barrier that allows the passage of water, ions, and small solutes into the urinary space while restricting the passage of cells and macromolecules. The three layers of the glomerular filtration barrier include the vascular endothelium, glomerular basement membrane (GBM), and podocyte epithelium. Podocytes are capable of internalizing albumin and...
Protein N-homocysteinylation involves a post-translational modification by homocysteine (Hcy)-thiolactone. In humans, about 70% of circulating Hcy is N-linked to blood proteins, mostly to hemoglobin and albumin. It was unclear what protein site(s) were prone to Hcy attachment and how N-linked Hcy affected protein function. Here we show that Lys(525) is a predominant site of N-homocysteinylation...
Aim: In this study we aimed to investigate the relationship between C-Reactive Protein (CRP)/albumin ratio, MII-1 and MII-2 indexes in hospitalization mortality due aortic dissection. Material Method: Patients who presented our emergency department with a sudden-onset, sharp stabbing chest pain diagnosed Stanford type A dissection were included study. Patients’ demographics such as age gender, ...
human serum albumin (hsa) is the most abundant protein constituent of blood plasma. this protein consists of a single polypeptide chain of 585 amino acid residues, which has many important physiological functions. hsa can bind and carry many drugs, including anticoagulants, tranquilizers, and general anesthetics. some technique such as: fluorescence spectroscopy, three-dimensional fluorescence ...
background: combination of glycation and oxidation is associated with diabetes mellitus. the aim of this study was to clarify the effect of glycated proteins in presence of transition metal ions on production of reactive oxygen species (ros) in rat hepatocyte suspension. methods: glycated albumin was prepared by incubation of bovine serum albumin with 100 mm glucose in 0.3 m phosphate buffer a...
background glucose is an essential element in the supply of body’s energy. in diseases such as diabetes, glucose increase is associated with disturbance in metabolism. cortisol is an important hormone in the regulation of glucose metabolism, and human serum albumin (hsa) is one of the most important glucose and cortisol transmitters in blood. interaction between albumin and these ligands could ...
vitamin c, an antioxidant substance soluble in water, can react with amino groups of proteins to form schiff bases. as diabetes leads to glycation of various protein which has effect on structure and biochemical activity of them, the inhibition of this process seems very vital. for several years researches in this field have done their best to recognize the antidiabetics compounds. the aim of t...
three new rimantadine schiff bases (rsbs) were prepared, and then the interaction of rsbs with bovine serum albumin (bsa) was investigated using fluorescence, synchronous fluorescence, uv-vis absorption spectroscopy under physiological conditions. the results showed that the three rsbs effectively quenched the intrinsic fluorescence of bsa via static quenching. binding constant (ka), number of ...
mechanism of the binding of lomefloxacin (lmf) with human serum albumin has been studied at physiological ph (7.4) using fluorescence spectroscopic technique. lmf is a third-generation fluoroquinolone antibiotic that exhibits striking potency against a broad spectrum of gram-negative and gram-positive bacteria through inhibition of dna gyrase. lomefloxacin is a drug that is excreted in urine an...
background: in recent years we have successfully adopted an in vitro hepatogenic differentiation of mesenchymal stem cells (mscs). in this protocol the biologically active hepatocyte-like cells were differentiated from the stem cells isolated from either bone marrow or umbilical cord blood (ucb) samples. the aim of the present study was to compare the efficiency of the hepatogenic differentiati...
