background and aims: the causal agents of viral lettuce big vein disease are two viruse, lettuce big vein associated virus (varicosavirus) and mirafiori lettuce virus (ophiovirus). these viruses have coat proteins of similar size but have different morphologies and serologically unrelated.the purpose of this study was to distinguish and detect lbvav and milv in lettuce fields in tehran province...
results almost 8% of the personnel showed positive tst (over 10 mm) reaction while 29% of them had considerable t - cell reactivity against ppd in elispot assays. however, the esat - 6 reactivity was found only in one case of hcws. no correlation was found between the patterns of the reactions and the age or the duration of the employment or previous vaccination history of the participants. the...
The authors wish to make the following corrections to this paper [1]: [...].
the aim of this study was to evaluate an enzyme - linked immunosorbent assay (elisa) for the detection of anti - helicobacter pylori (h. pylori) specific igg antibodies in specimens of oral fluid. all subjects over the age 18 years undergoing endoscopy for any reason were asked to participate in the study. two groups of 44 patients in each were selected as hp+ and hp-. at the same time, 5 milli...
Evidence supporting the occurrence of starving larval fish in the ocean was mainly circumstantial (May, 1974; Jones and Hall, 1974: Lasker, 1975) until recently, when the presence of starving ocean-caught larval northern anchovy, Engraulis mordax, was documented using histological criteria (O'Connell, 1980). Subsequently, using similar criteria, Theilacker (1986) quantified starvation-induced m...
The Society for Biological Therapy held a Workshop last fall devoted to immune monitoring for cancer immunotherapy trials. Participants included members of the academic and pharmaceutical communities as well as the National Cancer Institute and the Food and Drug Administration. Discussion focused on the relative merits and appropriate use of various immune monitoring tools. Six breakout groups ...
Enzyme-linked immunospot, or ELISPOT, assay allows the detection of low frequencies of cells secreting various molecules. ELISPOT can be used in many areas of research and, because of its high sensitivity, has the potential to become a valuable diagnostic tool. Based on the same "sandwich" immunochemical principles as enzyme-linked immunosorbent assay, ELISPOT is easy to perform and quantify th...
