BACKGROUND In this study, two-dimensional gel electrophoresis (2-DE) method was applied to determine and compare the protein spots expressed in the two field isolates of Leishmania major and recovered from the patients who were clinically sensitive and resistant to Glucantime® treatment. METHODS Leishmania parasites were isolated from the cutaneous lesions of two CL infected patients in Shira...

The global analysis of proteins is now feasible due to improvements in techniques such as two-dimensional gel electrophoresis (2-DE), mass spectrometry, yeast two-hybrid systems and the development of bioinformatics applications. The experiments form the basis of proteomics, and present significant challenges in data analysis, storage and querying. We argue that a standard format for proteome d...

Cystic echinococcosis (CE) is an anthropozoonotic disease with worldwide distribution and is caused by the cestode Echinococcus granulosus. Anaphylactic shock induced by CE rupture is a serious complication especially in patients with hydatid infections, as the resulting leakage of fluid contains highly toxic endogenous antigen. We aimed to isolate and identify the antigens of specific IgE and ...

Since RNA molecules commonly form stable secondary structures, agarose gel size-fractionation of RNA is routinely achieved by chemical denaturing conditions during electrophoresis. This implies the use of toxic compounds such as methylmercuric hydroxide (1), formaldehyde (3) or cumbersome electrophoretic conditions using glyoxal and dimethylsulfoxide (4) after RNA denaturation. Here, we describ...

A model for DNA implementation of Royal Road evolutionary computations is presented. An encoding for a Royal Road problem is presented. Experimental results utilizing 2-d denaturing gradient gel electrophoresis (2-d DGGE) and polyacrylamide gel electrophoresis (PAGE) for separation by tness in this sample Royal Road problem are shown. Suggestions for possible use of the MutS and MutY proteins a...

Background: Atherosclerosis is a chronic inflammation that interferes with blood arteries functions due to the accumulation of low density lipids and cholesterol. Objective: To investigate the effect of aqueous extract and saponin fraction of Tribulus terrestris L. (TT) on the proteome and expression of intracellular adhesion molecule-1 (ICAM-1), vascu...

The alpha-2 macroglobulins from human serum and plasma were isolated by Bio-Gel P-300 and A5m gel filtration. The material showed a single peak on sedimentation velocity ultracentrifugation, a mol wt of 650,000 by sedimentation equilibrium ultracentrifugation, and a major precipitin arc in the alpha-2 macroglobulin region by immunoelectrophoresis against whole human serum. Two bands were observ...

Renin was purified from 47 kg of hog kidney to produce enough enzyme for enzymatic and physicochemical characterization. The procedure included extraction at pH 3.5 in the presence of protease inhibitors, two ammonium sulfate precipitations, ion exchange chromatography on Sepharose-hexamethylenediamino-pepstatin gel, gel filtration, and isoelectric focusing. Renin, 2.3 mg, with a specific activ...
