soybean mosaic virus (smv) which belongs to the virus family potyviridae, causes a disease in soybean that is present in soybean-growing areas of the world, and is widely distributed in northern iran. detection of smv is very important for disease management. in the present study several serological and molecular (nucleic acid- based) methods of rapid virus detection were compared. serological ...
A Tn5 mutant strain of Sinorhizobium meliloti with an insertion in tpiA (systematic identifier SMc01023), a putative triose phosphate isomerase (TPI)-encoding gene, was isolated. The tpiA mutant grew more slowly than the wild type on rhamnose and did not grow with glycerol as a sole carbon source. The genome of S. meliloti wild-type Rm1021 contains a second predicted TPI-encoding gene, tpiB (SM...
Using sera from 340 patients with syphilis the Treponema pallidum immune adherence (TPIA) test was compared with the glass plate, T. pallidum haemagglutination (TPHA), and fluorescent treponemal antibody-absorbed (FTA-ABS) tests. The results of the TPIA test agreed with those of the glass plate, TPHA, and FTA-ABS tests in 65%, 82%, and 73% of cases respectively. In the quantitative TPIA test no...
بیماری برگ سفیدی نیشکر یکی از مخربترین بیماری های نیشکر در آسیا می باشد. این بیماری به عنوان یک بیماری فیتوپلاسمایی بر روی نیشکر در استان خوزستان نیز گزارش شده است. علاوه بر نیشکر، مرغ نیز علائم برگ سفیدی ناشی از فیتوپلاسما را در این استان نشان می دهد. به منظور خالص سازی نسبی فیتوپلاسمای عامل برگ سفیدی از نیشکر آلوده به بیماری استفاده شد. آموده حاصل از خالص سازی نسبی 40 گرم بافت آلوده به خرگوش ...
Antibody titres were measured in patients with clinical syphilis, and the effect of treatment on the results of the Treponema pallidum immune adherence (TPIA) test is reported. In the Treponema pallidum haemagglutination (TPHA) test little change in antibody titre occurred after treatment while in the fluorescent treponemal antibody-absorbed (FTA-ABS) test only a slight decrease occurred. The d...
Clinical investigations using the Treponema pallidum immune adherence (TPIA) test as reported by Nelson (1953) were performed only by Olansky et al in 1954. In this paper an improved method of the TPIA test is described. The test was simple to perform and was highly specific for antitreponemal antibody. Furthermore, as it was possible to use heated T. pallidum as antigen the antigen suspension ...
Human immunodeficiency virus type 1 nucleocapsid protein is a major structural component of the virion core and a key factor involved in proviral DNA synthesis and virus formation. 2,2'-Dithiobenzamides (DIBA-1) and related compounds that are inhibitors of NCp7 are thought to eject zinc ions from NCp7 zinc fingers, inhibiting the maturation of virion proteins. Here, we show that the presence of...
A rapid and specific dot-enzyme immunoassay (DIBA) using monoclonal antibody was introduced for detection of Trichomonas vaginalis antigen in vaginal and urethral materials. The results of DIBA were compared with culture findings of the parasite in 245 female patients. Taking culture as the reference method, DIBA had a sensitivity of 92% and a specificity of 93%. The predictive value of a posit...
In search for selective ligands for the muscarinic acetylcholine receptor (MR) subtype M2, the dimeric ligand approach, that is combining two pharmacophores in one and the same molecule, was pursued. Different types (agonists, antagonists, orthosteric, and allosteric) of monomeric MR ligands were combined by various linkers with a dibenzodiazepinone-type MR antagonist, affording five types of h...
