In higher eukaryotes, mRNA degradation and RNA-based gene silencing occur in cytoplasmic foci referred to as processing bodies (P-bodies). In protozoan parasites, the presence of P-bodies and their putative role in mRNA decay have yet to be comprehensively addressed. Identification of P-bodies might provide information on how mRNA degradation machineries evolved in lower eukaryotes. Here, we us...

introduction and aims: until today human stomach is the only recognized habitat of h. pylori . however, recruitment of dna-based methods has made possible the detection of h. pylori in water and oral cavity, thus suggesting faecal-oral and oral-oral routes for transmission of h. pylori , respectively. in this study yeast has been proposed as a common vector for transmission of h. pylori . thus ...

The disruption of the normal function and nuclear localization of the promyelocytic leukemia-associated protein (PML) may play a major role in the pathogenesis of acute promyelocytic leukemia. PML, which is concentrated in nuclear bodies (PML bodies), has been shown to have growth- and transformation-suppressive properties. In this study, we have examined the intranuclear distribution of PML in...

The purpose of this paper is to report the results of a study of the mucin, or mucin-like metachromatic substance, sometimes found in the white matter of the brain. This substance, occurring in small masses, has been referred to as " mucocytes." During the course of work on " grass sickness " in horses, these masses have been found; it therefore has become urgent, before continuing this investi...

Water bodies and water systems are essential for survival and protecting them against terrorist threats like biochemical warfare agents and against threats from toxic industrial chemicals is of at most importance. This paper will examine the issues in protecting water bodies and water systems against waterborne biochemical warfare. We will also present preliminary ideas on a sensor network-base...

"It ia certain that all bodies whatsoever, though they have no sense, yet they have perception; for when one body b applied to another, there is a kind of election to embrace that which i s agreeable, and to exclude or expel that which i s ingrate; and whether th,e body be alterant or altered, evermore a perception precedeth operation; for eke all bodies would be like one to another."
