UNLABELLED The differentiation between exudates and transudates is the initial step in the analysis of pleural effusions as it often gives an indication of the underlying pathophysiologic process, the differential diagnosis, and the need for further investigations. Four classifications have been suggested in the literature: Light's criteria, serum-effusion albumin gradient, effusion cholesterol...

Rat serum albumin has been labeled with dilactitol-125I-tyramine, (125I-DLT) a radioactive tracer which remains entrapped within lysosomes following cellular uptake and degradation of the carrier protein. Similar kinetics of clearance from the rat circulation were observed for albumin labeled conventionally with 125I or 125I-DLT-albumin, both proteins having circulating half-lives of approximat...

A cDNA clone library was prepared from liver poly(A) RNA pf non-estrogenized Xenopus laevis. Albumin coding sequences were screened by hybridization to a cDNA prepared from poly(A) RNA enriched by sucrose density gradient centrifugation, and by a sensitive solid-phase radioimmunoassay to detect clones that contain templates for albumin antigenic determinants. Nine clones were obtained by this a...

BACKGROUND Accumulation of pleural and peritoneal fluid is seen in some diseases. In order to diagnose the disease and start the treatment, one of the most important actions will be to differentiate between exudates and transudates. The objective of this study was to determine the diagnostic value of measuring the specific gravity of the fluid through refractometer and strip in differentiation ...

Highly purified chromaffin granule ghosts contain about 100 (89.1-110.2, n = 8) nmol of long-chain free fatty acids/mg of protein. About 40% of the fatty acids were mono- and polyunsaturated, of which arachidonate accounted for approximately 20%. Incubation with fatty acid-free bovine serum albumin selectively depleted the ghosts of unsaturated fatty acids. The effect of a series of long-chain ...

in this present study, we examined the differentiation potential of human bone marrow derived mesenchymal stem cells (hbmscs) into hepatocytes on a three-dimentional (3d) nanofibrous scaffold formed by poly (ε-caprolactone) (pcl), collagen and polyethersulfone (pes). the nanofiber was prepared by the electrospining technique. hbmscs were isolated using combining gradient density centrifugation ...

Human neutrophils contain a rapidly mobilizable pool of so-called secretory vesicles distinct from the azurophil granules and specific granules. Using human albumin as a marker for these intracellular vesicles in immuno-electron microscopy, we found that part of the cytochrome b558 in non-purified whole blood neutrophils colocalized in these vesicles. This was detected with monoclonal antibody ...

Objective: To evaluate the capability of ascitic fluid dipstick results for pH, glucose, and protein in order to predict a low serum-ascites albumin gradient (SAAG) at the bedside of the patient in the emergency department (ED). Methods: This prospective cross-sectional study was conducted during one year in the ED of Afzalipour hospital in Kerman, Iran. ...

BACKGROUND The classification of ascites as 'exudative' and 'transudative' based on ascitic fluid total protein (AFTP) has been challenged in many clinical conditions like cardiac ascites, patients on prolonged diuretic therapy and malignant ascites because it had poor diagnostic efficacy. These drawbacks have led to the development of another approach to classify ascites, which is based on Ser...
