Evaluation of polyvinyl alcohols as semipermanent mountants for fluorescent-antibody studies.

Synthesis of Unsymmetrical Ethers Catalysed by Polyvinyl Sulfuric Acid & PVSA / Nano RH SiO2 as a Novel Solid Acid Nanocomposite

The methodology involves preparing polyvinyl sulfuric acid as a solid acid by simple mixing ofpolyvinyl alcohol with chlorosulfonic acid in CH2Cl2 at room temperature. The catalytic ability ofthe solid acid was investigated for the facile conversion of benzylic alcohols to the unsymmetricalethers with aliphatic alcohols in the presence of the solid acid. Results show that the solid acid isan ap...

Diagnosis of Intestinal Amoebiasis with Indirect Fluorescent Antibody Test

SUMMARY The results of direct stool examination in 102 watery and bloody diarrhea patients were compared with the presence of antibodies against Entamoeba histolytica with Indirect Fluorescent Antibody Test. Besides 22 healthy individuals included in this study as control group. It was found that 22 patients (21.5%) with a sera titre higher than 1/320 bad only 9 (8.8%) positive E. Histolytica ...

Electrochemical Evaluation of Polyvinyl Butyral Coating Containing Polypyrrole/ZnO Nanocomposite for Corrosion protection of Al Alloy

In this work, polypyrrole/ZnO nanocomposite (PPy/ZnO NC) was produced through synthesis of polypyrrole polymer in the presence of ZnO nanoparticles. The corrosion behavior of polyvinyl butyral coatings without and with different weight percentages of nanocomposite on the surface of 7075 Al alloy was investigated in 3.5% NaCl solution at different immersion times using electrochemical impedance ...

Serological Evaluation of Experimental Toxoplasma gondii Infection in Cats by Using Immunoblotting Based on an Affinity Purified Surface Antigen

Toxoplasma gondii is an apicomplexan parasite that infects human and almost all warm-blooded animals. The life cycle of the parasite includes an asexual reproduction in intermediate hosts (Mammals and birds) and a sexual reproduction in definitive hosts (Felidae). Cats are both the intermediate and the definitive host for T. gondii. The aim of this study was to investigate anti-T. gondii antibo...
