background: it has been claimed that by using different washing methods, the sperms can be separated according to size, motility, density, chromosomal content and surface markings and charge. these methods also reduce sperm chromatin deficiencies and screen the sperms before applying in assisted reproduction techniques. objective: this study compared simple density gradient methods and a combin...

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. all patients with diagnostic or therapeu...

conclusions albumin gradient method is the enrichment of y-bearing chromosome sperms. separation of spermatozoa by albumin gradient method, introduced by ericsson, is a suitable method for sex selection of male offspring. this technique is safe, because it neither requires toxic materials during sperm separation, nor involves embryo manipulation. objectives the study aimed to assess the separat...

The objective of the study was to compare the serum-effusion albumin gradient (serum albumin level minus pleural effusion albumin level) to Light's traditional criteria (pleural fluid/serum total protein ratio greater than 0.5, pleural fluid/serum LDH ratio greater than 0.6, and pleural fluid LDH greater than 200 U/L) for identifying exudative pleural effusions. The design included prospective ...

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...

T HE SEPARATION of morphologically distinct cells by differences in their specific gravity has been demonstrated using density gradient centrifugation in several support media. From bovine serum albumin density gradient centrifugation experiments, morphologically similar lymphocytes have been shown to consist of several closely spaced, discontinuous, discrete populations.5 In addition, erythroc...
