The isolated cells of rabbit adrenal glands were separated by the method of sedimentation at a linear gradient of albumin concentration and incubated with 14C-cholesterol. The corticosterone and cortisol produced by the separated cells were fractionated by thin-layer chromatography and the radioactivities in these steroids were measured. The more rapidly sedimenting cells showed a greater ratio...

Albumin is an expensive drug which imposes relatively high cost on the health care system. Doing ABC analysis in Shahid Motahari Hospital, it was revealed that albumin is categorized in class A. Therefore, the present study aimed to evaluate the pattern of albumin use and the physicians' adherence to evidenced-based albumin guidelines in this large general non-teaching hospital in Shiraz, Iran....

This laboratory previously reported changes in normal human serum albumin stored under various conditions for 5 years. This report demonstrated that coordinated use of chromatography and ultracentrifugation offered a sensitive method for detecting protein alterations (1). In the present studies, which utilized the same method after another 5-year interval, the progress of these changes has been...

The aim of this study was to investigate the interrelation between splenic siderotic nodules, hypersplenism and liver function in patients with liver cirrhosis. The splenic enhanced susceptibility-weighted angiography (ESWAN) and conventional magnetic resonance images of 33 patients with liver cirrhosis were retrospectively studied and the ESWAN images were graded. The distribution and prevalen...

Overproduction of superoxide (O2*) occurs in glomerular disease and may overwhelm the capacity of superoxide dismutase (SOD), thereby intensifying oxidant injury by O2* and related radical species that disrupt the glomerular capillary permeability barrier to protein. We examined the efficacy of the SOD mimetic tempol in preserving glomerular permeability to protein using 1) a rat model of glome...

An injectable polyethylene glycol-crosslinked albumin gel (AG) supplemented with hyaluronic acid as a matrix for autologous chondrocyte implantation was evaluated with regard to its impact on angiogenesis. Healthy articular cartilage and intervertebral discs (IVD) are devoid of blood vessels, whereas pathological blood vessel formation augments degeneration of both theses tissues. In contrast t...

IEF simulation is an effective tool to investigate the transport phenomena and separation performance as well as to design IEF microchip. However, multidimensional IEF simulations are computationally intensive as one has to solve a large number of mass conservation equations for ampholytes to simulate a realistic case. In this study, a parallel scheme for a 2D IEF simulation is developed to red...
