Current research to harness the power of P2P networks involves building reliable Semantic Peerto-Peer (SP2P) systems. SP2P systems combine two complementary technologies: P2P networking and ontologies. There are several types of SP2P systems with applications to knowledge management systems, databases, the Semantic Web, emergent semantics, web services, and information systems. Correct semantic...

To generate a model of mammalian karyotype evolution and to extend our knowledge of the evolutionary relationships of mammals, it is helpful to deduce ancestral chromosomal arrangements. Of particular interest would be a global comparison among the 3 major extant groups of mammals, since this would reveal the most ancient arrangements of the mammalian genome and allow us to follow chromosomal r...

UNDERSTANDING genetic inactivation and reactivation in a developing organism is the key to understanding cytodifferentiation. One phenomenon which may help us formulate the proper questions about differentiation is the inactivation and reactivation of whole chromosomes or large segments of chromosomes during development. In this paper I am going to describe one such system of chromosomal modifi...

With the first issue of 2010, volume 103, the successful tenure of Klaus T. Preissner as the Editor-in-Chief of Thrombosis and Haemostasis over the past seven years has come to a worthy close. While he continues to serve as a Section Editor, his dedicated service and continuous hard work for the journal have earned him a well deserved rest from his Editor-in-Chief duties. As Editor-in-Chief, Kl...

The purpose of this study was to determine the fluoride levels in water, soil and tea, and to identify the major fluoride minerals in soil that supply water with fluoride ions. Another aim was to study the prevalence of dental fluorosis in permanent dentition of the school children of the Gaza Strip. Monitoring of fluoride levels in 73 groundwater wells and 20 topsoil samples for the last three...

The number of the solitary lymphoid follicles occurring in the connective tissue layer of the mucous membrane increased in chickens fed with B. subtilis supplementation. According to the microbiological examination the dietary inclusion of Bacillus subtilis was significantly reflected in the chicken caecal samples. The birds from the groups fed Bacillus subtilis consequently showed stronger res...

The endotoxins of gram-negative bacteria in minute amounts elicit an array of characteristic physiological alterations in mammals including such diverse phenomena as production of fever (1, 3), stimulation of resistance to infection (12, 21, 29), and protection against radiation injury (26). Higher dosage induces a state of stress, acute shock, or eventual death. In tumorbearing animals, extens...
