canine ehrlichiosis is a zoonotic rickettsial disease transmitted by ticks. in the present study, 198 companion dogs of different ages were examined for serum antibody detection against ehrlichia canis by means of immunochromatography assay. the dogs were selected among referred cases to veterinary hospital of shahid chamran university of ahvaz, southwestern iran from november 2008 to march 201...

High-speed liquid chromatography employing an ultraviolet photometric detector has been applied to the simultaneous determination of hippuric and m-methylhippuric acids in urine. Reversed-phase partition chromatography is carried out on a ,tBondapak C18 column with methanol-water as the eluent system. This method obviates the necessity for isolation or reaction of these acids before assay. The ...

The total phenol content and the anti-acetylcholinesterase activity were compared in olive leaf (OL) extracts obtained using both subcritical water extraction (SbWE) conventional solvent (ethanol-water). method proposed by Ellman (in vitro) was used to study inhibitory of acetylcholinesterase (AChE). phenolic compounds AChE activities OL varied depending on method. Thus, extract technique (220 ...

cancer is a major global problem and is the second leading cause of mortality in the developed countries.resistance to current chemotherapeutics and high incidence of adverse effects are the two principal reasons for developing new anticancer agents. phenylacetamide derivatives can act as potential anticancer agents. synthesis and screening of 2-(4-fluorophenyl)-n-phenylacetamide derivatives in...

two capillary zone electrophoresis (cze) methods were developed in this study, one using an acidic buffer (sodium citrate ph = 2.5) and the other using a basic buffer (sodium tetraborate ph = 9.8). the two methods were compared on the basis of repeatability and reproducibility of results and the cze method developed with the basic buffer was then selected for further studies. the method was ful...

conclusions: it was concluded that the elisa is a suitable method for large scale screening of antibodies against aspergilloma. the easy techniques have shortened the required time of tests (approximately 1.30 hours for our elisa, as opposed to 2.30 hours with commercial elisa kit). this may be a substantial benefit for large numbers of samples that should be tested. materials and methods: an i...
