Some conjectures related to the radical theory of rings are still open. Hence, research on is being investigated by some prominent authors. On other hand, results can be implemented in another branch or structure. In theory, it interesting bring classes into graded versions. this chance, we implement a qualitative method conduct Brown-McCoy class restricted as objective. We start from known fac...

McCoy-Plovdiv cells represent a serum-free in vitro system, which is suitable not only for diagnostic purposes but also for studies on the biological activity of different substances. In addition, it can be used for developing an expression system for production and purification of various proteins. Isolation of successfully transfected cells is an important step in this process and different s...

To my father, my first and foremost scientific and personal mentor. data from the McCoy group enabled the rotational analysis of Section 3.1, and geometries and MULTIMODE vibrational frequencies from the Bowman group enabled the discussion of Section 3.2.

The effect of polyethylene glycol (PEG) on the isolation of Chlamydia trachomatis was evaluated in our laboratory. Initial range-finding experiments demonstrated that the number of chlamydial inclusion bodies increased with increasing PEG concentrations. However, PEG concentrations above 10.5% became progressively more toxic to the McCoy cell monolayers. When 50 frozen clinical Chlamydia isolat...

A quantitative assay for infective variola virus particles was developed which is based on the enumeration of cells containing fluorescent viral antigen after infection of McCoy cell monolayers. The direct fluorescent-antibody technique was employed to stain cells. The efficiency of virus adsorption was markedly enhanced by centrifugation of virus inoculum onto McCoy cell monolayers at 500 x g ...

A fragment of a right dentary with one postcanine tooth from the Upper Triassic (Rhaetian) Scots Bay Member of the McCoy Brook Formation at Wasson Bluff, Nova Scotia, Canada, represents the first record of the tritylodontid cynodont Oligokyphus from the early Mesozoic of eastern North America. In addition, three dissociated postcranial bones from the same horizon and locality are referable to d...

We compared growth of the recently discovered respiratory pathogen Chlamydia pneumoniae in McCoy, HeLa 229, BHK-21, and HL cells. When cells were not pretreated with DEAE-dextran, HL cells had significantly higher mean numbers of inclusion-forming units (IFUs) on initial inoculation than the other cell lines. When cells were pretreated with DEAE-dextran, HeLa 229 and HL cells had equivalent mea...

In an earlier study, Ford and McCandlish (1969) isolated TRic agents, by the yolk-sac method, from fifteen of 133 urethral scrapings of men with nongonococcal urethritis. Gordon and Quan (1965) had previously found that TRIC agents would propagate in irradiated McCoy cells and could be readily demonstrated by the resulting inclusions which stained purple with iodine because of their glycogen co...
