Left/right, up/down: the role of endogenous electrical fields as directional signals in development, repair and invasion

Article Abstract:

Directional signals are extremely useful and they are involved in the development and regeneration processes as well as guiding pathogens that invade other organisms. The recent data is highlighted and the possible mechanisms by which the electrical fields might affect biological processes are discussed.

Prions at the crossroads: the need to identify the active TSE agent.

Article Abstract:

The possibility of nucleic-acid-induced PrP(super SC) associated with the inducer nucleic acid as the components of the infectious agent is examined. There is no direct involvement of PrP(super SC) in the prion pathogenesis.

Pathogenic archaea: do they exist?

Article Abstract:

Archaea are microorganisms that are distinct from bacteria and eukaryotes. By investigating the potential for archaea to be or become pathogens, the assumption whether archaeal pathogens exist or not is reviewed.
