This work on the level of an'tistreptolysin titer in the serum of patients with acute glomerulonephritis is part of a study being conducted by the Departments of Medicine and Pediatrics on the role of infection in acute and chronic glomerulonephritis. The literature and texts list the most heterogeneous types of infection (influenza, diphtheria, measles, the common cold, sore throat, exposure, ...

Background: After substitution of Pentavalent vaccine with diphtheria, tetanus, pertussis (DTP) in the Iranian National Vaccination program with 3 Pentavalent (three times vaccination with Pentavalent vaccine at months 2, 4, and 6) in 2014 and the lack of published research in the field of immunogenicity of pertussis component of this vaccine, the efficacy of pertussis vaccine was studied 6 mon...

A new latex agglutination test for rubella virus was used to test sera with a hemagglutination inhibition titer of -8 (97 specimens) or >256 (158 specimens). Maximum latex agglutination test sensitivity was achieved when low-titer sera were tested undiluted and high-titer sera were diluted (1:10). A modification of the protocol of the manufacturer resulted in a latex agglutination-hemagglutinat...

Tilapia aurea showed a specific immune response to Salmonella typhimurium. S. typhimurium was introduced into the gut of T. aurea by force-feeding. S. typhimurium was isolated from the fish viscera after 15 days, but at 30 days viable cells were not detected. T. aurea had an antibody titer to S. typhimurium after 30 days which was fivefold greater than the natural background antibody titer. An ...

Since the ordinary tests for diagnosis chronic amebic colitis looks to be unsufficient. We try to design the following study. Our study seeks the importanc.;e of "IFA" (Indirect Immuno Fluorescent Aniti body). Among 145 patients with amebic colitis Entamoeba hystolitica observed with reapeted and specified tests. In searh of serologic tests, antibody range in 20 patients who had amebic coliti...

In order to study and evaluate the indirect immunofluorescent test and the ratio of CD41ymphocytes to CD8 lymphocytes, 97 cases of positive candida cultures were selected from among 400 patients referring to the hospital and suspected of candidiasis. In this study 39% of the patients had an antibody titer less than 1: 160 No significant correlation was seen between canclidiasis and the resu...

In this application note, we describe a novel method to rapidly measure the size and concentration of Adeno-Associated Virus (AAV) utilizing the Nanoparticle Tracking Analysis (NTA) technique and a gold labeling method. By labeling AAV capsids with small gold nanoparticles, we were able to increase the amount of light scattered by each capsid, enabling rapid NTA characterization to determine th...

On any given day, about 35% of 80- to 85-day-old socially naïve male (SNM) lobster cockroaches (Nauphoeta cinerea) spontaneously adopted an aggressive posture (AP) without encountering another male [spontaneous AP (SAP)]. Although SAP SNMs showed significantly higher release of the pheromone 3-hydroxy-2-butanone (3H-2B) than non-SAP SNMs, there was no significant difference in hemolymph juvenil...
