Wassermann and Ficker (1922) succeeded in isolating seven virulent strains of Treponema pallidum from the serum from eighty to ninety primary chancres. One strain, B:,, was kept and cultivated in an anaerobic fluid medium consisting of diluted horse serum to which a piece of boiled liver was added, and at that time, the strain proved virulent for rabbits after a series of subcultures (Reiter). ...

Axial filaments were isolated and purified from Reiter treponemes after detergent solubilization of the cells" outer envelope. The axial filaments were separated from the spirochetal cells by shearing, purified by density gradient centrifugation, and fragmented by ultrasonication. Acrylamide gel electrophoresis of dissociated filaments revealed two major protein bands. Gel diffusion precipitin ...

Our focus in this paper is on natural exoge-nous actions (Pinto 23]), namely those which occur in response to known laws of physics, like a ball bouncing at times determined by Newtonian equations of motion. The property of such actions that we wish to capture is that they must occur at their predicted times, provided no earlier actions (natural or agent initiated) prevent them from occurring. ...

Algorithms that generate expressions to identify a referent are mostly tailored towards objects which are in some sense conceived as holistic entities, describing them in terms of their properties and relations to other objects. This approach may prove not fully adequate when referring to components of structured objects, specifically for abstract objects in formal domains, where scope and rela...

Two methods of performing serological screening tests for syphilis are compared. One consisted of the Venereal Diseases Reference Laboratory (VDRL) slide test, the cardiolipin Wassermann reaction (CWR), and the Reiter protein complement fixation test (RPCFT) performed manually; the other was a fully automated system using two Technicon AutoAnalyzers (AAII), one for the automated reagin test (AR...

Dr. Russel J. Reiter was awarded his fifth honorary title by the National University of Cuyo, Argentina, for exemplary contributions towards unraveling mysteries pineal gland and, importantly, its major secretory product, melatonin. This commentary provides a glimpse accomplishments and summary speech during ceremony.
