background and aims: celery mosaic virus (cemv) is one of the causal agents of viral diseases in celery (apium graveolens). cemv is a member of the potyvirus genus in potyviridae family. the virus is naturally transmitted by aphids in a non-persistent manner. during growing season 2006-2007 viral disease symptoms were observed in celery fields grown in tehran province (bage daneshkade, mohamads...
Rabbit antibodies for Candida albicans, reacting in agglutination and fluorescent-antibody reactions, were present in both IgM and IgG protein fractions. The two types of immune globulins were separated from ammonium sulfate-precipitated gamma-globulin either by filtration through a column of Sephadex G-200 or by diethylaminoethyl column chromatography performed by stepwise elution with various...
introduction: polyclonal antibodies are required to be affinity purified. improved purification methods of polyclonal antibody provide an opportunity to pick the most purified immunoglobulins as a primary or secondary antibody in immunoassays that are included in many vaccine studies. two common techniques for purifying proteins is salt precipitation and chromatography purification. our work fo...
the rotavirus nonstructural protein 4 (nsp4), is a multi functional protein that play key role in both viral morphogenesis and cytopathic effect associated with cell death. however, the complete biological effect of nsp4 remains to be clarified. since to obtain further knowledge about this protein there is a need for recognizing antibody and there is no commercial antibody against this protein...
burnout is a response to the chronic work stress which is prevalent mostly among the people who do people job, like teaching. the purpose of this study was to develop a valid and reliable instrument that can measure burnout in foreign language teachers. although some widely used instruments were developed before which measured burnout in teachers, a specific instrument which include specific sy...
In response to the outbreak of COVID-19, caused by the SARS-CoV-2 virus, several tests are needed for diagnosis of acute illness, contact tracking, diagnosis of asymptomatic infections, and assessment of herd immunity. While PCR is the standard test in acute type, serological tests have been developed and used to meet diagnostic needs due to the widespread prevalence of the disease. Unlike the...
Background: Each year, Human influenza A (H1N1) virus causes moderate to severe infections with a high prevalence throughout the world. Accordingly, the rapid, sensitive and cost-effective laboratory diagnosis based on viral antigen detection is important. Moreover, the generation of specific antibodies directed against Influenza antigens is essential to the success of both basic and applied re...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
Serological tests were performed on 380 cats with necropsy-confirmed heartworm disease to compare the performance of currently available commercial laboratory and point-of-care heart-worm serological tests in a heartworm-endemic area. Overall, antigen tests detected 79.3% to 86.2% of heartworm infections and were highly specific. Most cats with false-negative antigen tests had a single male wor...
