introduction: prostate specific antigen (psa) is one of the most sensitive markers for diagnosis of prostate cancer. immunoradiometric kit (irma) is a common and sensitive method for determination of psa in clinical laboratories. this kit has four major components: solid phase coated with monocolonal antibody, pair antibody labelled with i-125, series of standards in different ranges of concent...

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...

anti-human globulin was produced in iranian rabbits and goat by using human o serum mixed with freund's adjutants (complete or incomplete) for immunizing the animals. a titer of 1.4096 was obtained in rabbit and a titer of 1.2056 was obtained in goat. quality-and quantity-wise, goat's serum appeared to be better than rabbit's serum.

background and aims: in this lab trial, the effect of scaffold based on human serum albumin (hsa) and hydroxyapatite nanoparticles (ha nps) on mouse spermatogonial cell line (scl) was investigated. materials and methods: to synthesize ha nps, calcium nitrate and diammonium phosphate at ph 13 were gently added and heated at 100 ºc for 24 hours. then serial concentrations of ha nps was separately...

in this research, the magnetite nanoparticles (fe304) were prepared by coprecipitation of fe3+ andfe solution in alkaline medium. two kinds of surfactants, cetyl tri methyl ammonium bromide(ctab) and cetyl pyridinum chloride (cpc) were used in the synthesis. fe304 nanoparticles werecoated with human serum albumin (hsa) and bovine serum albumin (bsa). characteristics ofcoated magnetic nanopartic...

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 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 ...

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...
