Childhood obesity is a serious problem for increasing numbers of children around the world. According to the International Obesity Task Force, 1 of 10 schoolaged children worldwide is overweight or obese, a number totaling 155 million; of these, 2-3% are obese. Prevalence is highest in the Americas and Europe, followed by the Near/Middle East, with smaller but growing numbers in the Asia-Pacific and Sub-Saharan regions of the world.In the United States, which provides the data for much of this report, prevalence (...) continues to rise. The most recent nationally representative data indicate that 33.6% of individuals aged 2-19 years were overweight and 17.1% were at risk for overweight in 2003-2004, compared to 28.2% and 13.9% in 1999-2000, respectively. In this age group, the prevalence of overweight or at risk for overweight was highest among Mexican Americans, followed by Non-Hispanic blacks and Non-Hispanic whites, and a higher percentage of males were overweight compared to females.

Structural change in the cellular prion protein, PrPC to a ProteinaseK‐resistant β‐sheet‐rich insoluble form PrPSC and its accumulation have been considered to be central to the pathogenesis of the prion diseases (TSE). In a recent paper, Deleault et al have shown that specific endogenous RNA molecules can induce in vitro structural conversion of endogenous PrPC to PrPSC.1 Small highly structured synthetic RNAs can also induce this conversion process.2 However, recent in vivo results show that PrPSC is not directly involved in (...) the prion pathogenesis.3 It is possible, however, that nucleic‐acid‐induced PrPSC associated with the inducer nucleic acid could be the components of the infectious agent.

THE HOLY GAL - and European, medieval legends - a mysterious vessel, for the sake of approaching and engaging in its good deeds, the knights performed their exploits. It was commonly believed that this is the Cup with the blood of Jesus Christ, which Joseph of Arimathea gathered, who removed from the cross the body of the crucified Christ. It was often assumed that this cup originally served Christ and the Apostles at the time of the Last Supper; was the (...) Cup for the communion of the first Liturgy. Gral is a mystery, invisible to the unworthy, but also worthy of being different. Gral has the ability to miraculously fill his elect with unearthly things, which was first discovered during the imprisonment of Joseph Artmofeysky. (shrink)

An epistemic logic is built up on the basis of an analysis of two skeptical arguments. the method used is to first construct an inference relation appropriate to epistemic contexts and introduce "a knows that..." as an operator giving rise to sentences closed with respect to this new concept of inference. soundness and completeness proofs are provided using auxiliary three-valued valuations.

It is difficult to describe this book without praising it. Collected here in one volume are some thirty-six high quality translations into English of the most important foreign-language works in mathematical logic, as well as articles and letters by Whitehead, Russell, Norbert Weiner and Post. The contents of the volume are arranged in chronological order, beginning with Frege's Begriffsschrift—translated in its entirety—and concluding with Gödel's famous "On Formally Undecidable Propositions" and Herbrand's "On the Consistency of Arithmetic". The translation of the (...) Gödel article is a small masterpiece, and is especially welcome in view of some of the rather poor efforts which have been made to render this important work into English. But this is more than a paste-pot job of anthologizing. Van Heijenoort and others have written prefaces to each of the included selections, in which are provided background historical and bibliographical information, comments on the intellectual currents which led to the production of the article, and, in many cases, a digest of the important theorems and concepts in the article itself. Each selection is a classic in its own right. In reading through the selections in this volume, one is struck by the extent to which purely mathematical problems and issues have controlled recent logical inquiry and have determined the development of various philosophies of mathematics. In the early stages, Frege and Peano were concerned with the logical reconstruction of arithmetic, and this led to the work of Russell and the logicist philosophy. Already in the development of the new logic there were certain problems which were resolved with Russell's theory of types—a device which many mathematicians felt to be rather artificial. The use of set theory, beginning with Cantor and reaching its maturity in Zermelo's 1904 proof of the well-ordering theorem, gave rise to a new set of difficulties concerning the axioms of choice, the continuum problem, and infinite sets. The two traditions are brought together in a common nexus of foundational problems by Weiner in 1914 and by Skolem's form of the Löwenheim theorem, given in 1920. Hereafter, the way is open for the rise of mathematical inquiry into the foundations of number systems, set theory and logic by Post, Skolem, von Neumann, Hilbert, Bernays, Gödel and many others. The work was far from completed by 1931, but a new and important tradition in mathematical inquiry had been established, and had come into its own. This book is, in effect, the record of an important chapter in the history of thought. No serious student of logic or foundations of mathematics will want to be without it.—H. P. K. (shrink)

Using covariant derivatives and the operator definitions of quantum mechanics, gauge invariant Proca and Lehnert equations are derived and the Lorenz condition is eliminated in U(1) invariant electrodynamics. It is shown that the structure of the gauge invariant Lehnert equation is the same in an O(3) invariant theory of electrodynamics.

Scientists in many fields are presently giving the closest attention to study of the potentials of the systems approach for understanding what cannot be comprehended with the analytical approach or, as V. A. Engel'gardt has put it, "an accumulation of material in reduced form." This approach is in some degree a gesture of despair. It is quite obvious that we now face the danger of drowning in the abundance of data accumulated in terms of "special" problems not tied into a (...) system, and that this threatens loss of general direction.

Desmosomes are junctions involved in intercellular adhesion of epithelial cells and hemidesmosomes are junctions involved in adhesion of epithelia to basement membranes. Both are characterised at the ultrastructural level by dense cytoplasmic plaques which are linked to the intermediate filament cytoskeleton of the cells. The plaques strongly resemble each other suggesting a relationship between the two kinds of junctions, as implied by their names. Recent characterisation of the molecular components of the junctions shows they are, in fact, quite unrelated implying (...) that structural similarity is fortuitous. The molecular biology raises many fascinating problems relating to their structure and function. (shrink)
