Examination of structure-function correlates in the human brain reveals that there is a high degree of functional specificity in the information transmitted over neural systems. It also appears that the human brain has a modular organization consisting of identifiable component processes that participate in the generation of a cognitive state. The effects of isolating entire modular systems or ...

Abstract Background In the present study, detection, characterization and virulence analysis of a field collected nucleopolyhedrovirus isolated from cotton leafworm, Spodoptera littoralis (Boisd.) (Lepidoptera: Noctuidae) was carried out. The obtained isolate, named SpliNPV-YW, diseased S. larvae in El-Menoufia governorate, Egypt. Results Transmission electron microscopy showed presence typical...

Abstract Background Metarhizium is one of the entomopathogenic fungi (EPF) that has been widely reported as a useful agent for controlling coconut rhinoceros beetle (CRB), Oryctes L. (Coleoptera: Scarabaeidae). Application this fungus biopesticide influenced by regional environmental conditions affect pathogenic activity against targeted pest. Several studies have proven native fungal isolates ...

trichomoniasis is a worldwide infection and due to its complications rapid and accurate diagnosis of infection especially in pregnant women is very important. in this study, development of a latex agglutination test using native antigens for rapid diagnosis of trichomoniasis is investigated. trichomonas vaginalis was harvested from tyis33 culture medium and anti trichomonas vaginalis antiserum ...

the relationship between female oviposition preference and offspring performance is a key area of study on the evolution of host specificity. this study investigates host prefer-ence of the polyphagous hover fly syrphus ribesii (diptera: syrphidae) and compares it with some components of its offspring`s performance. females and offspring were tested on six naturally used aphid hosts (blackberry...

The principles of magnetic separation aided by antibodies or other specific binding molecules have been used for isolation of specific viable whole organisms, antigens, or nucleic acids. Whereas growth on selective media may be helpful in isolation of a certain bacterial species, immunomagnetic separation (IMS) technology can isolate strains possessing specific and characteristic surface antige...

In the Janzen—Connell hypothesis, host-specific natural enemies enhance species diversity and influence the structure of plant communities. This study tests the explicit assumption of host specificity for soil pathogens of the genus Pythium that cause damping-off disease of germinating seeds and seedlings. We isolated Pythium spp. from soil of a tropical forest in Panama. Then, in an inoculatio...

This report describes the preparation of six monoclonal antibodies (MAbs) raised against a British isolate of porcine reproductive and respiratory syndrome virus (PRRSV), their characterization in terms of protein specificity and their reactivity with different PRRS viruses from Europe and the USA. Radioimmunoprecipitation and Western blotting studies of MAb reactivity with proteins from cell l...

Although a single electrophoretically uniform antibody component with specificity for the group carbohydrate may comprise the bulk of the gamma-globulin in rabbits immunized with streptococcal vaccines, this is not always the case. Not infrequently, electrophoresis may reveal multiple antibody components. Nevertheless, it has been feasible by various preparative procedures to isolate from a sin...
