Recently a concise expression for the subleading infrared singularity of dimensional-regularized gauge theories has been proposed. For conformal theories, such relation involves a universal eikonal contribution plus a non-eikonal contribution, related to the subleading term in the anomalous dimension of twist two operators with large spin. In this note we make use of the AdS/CF T correspondence...

BACKGROUND Studies have shown that supplementation of adult men with selenium-enriched yeast (SY) was protective against prostate cancer (PCa) and also reduced oxidative stress and levels of prostate-specific antigen. Here, we determined the effect of SY supplementation on global serum protein expression in healthy men to provide new insights into the mechanism of selenium chemoprevention; such...

OPSOMMING Die vroedvrou lewer deur die eeue been haar diens aan die gemeenskap en haar rol het saam met die mediese wetenskap ontwikkel. Navorsing is gedoen oor die hedendaagse rol van die vroedvrou in Suid-Afrika. Daar is bevind dat sy in die lewering van omvattende gesondheidsorg die geneesheer aanvul. Sy het voorkomende, koordinerende, terapeutiese, versorgings, opvoedings, besluitnemings en...

In die Suid-Afrikaanse situasie is die verpleegkundige 'n kernfiguur in die lewering van primêre gesondheidsorgdienste. In die voorsiening van ’n veilige omgewing het sy ’n sekondêre rol in behoefteidentifisering en voorligting en dieselfde geld vir die aspek van toereikende voeding. Haar rol in basiese voorkomende gesondheidsorg en die sorg van bejaardes, gestremdes en chroniese siekes word re...

The objective of this study was to determine the concentration of total selenium (Se) and the proportions of total Se comprised as selenomethionine (SeMet) and selenocysteine (SeCys) in the postmortem tissues of female pheasants (Phasianus Colchicus Torquator) offered diets that contained graded additions of selenised-enriched yeast (SY) or a single comparative dose of sodium selenite (SS). Thi...

We consider the problem of building an automated proof system for reasoning in contexts. Towards that goal, we first define a language of contextual implications, and give its operational semantics under the form of a natural deduction system using explicit context assertions. We show that this proof system has an equivalent straightforward logic program, which in turn can be reified, i.e. defi...

To truly understand the hydrologic and erosive processes that occur at catchment scale regarding land use soil management changes, intensive monitoring is required over a long period. Variables such as precipitation, flow rate suspended sediment concentration are fundamentals needed to estimate yield (SY). However, in order shed more light on effects of changes SY, traditional techniques can be...

Downloa kground: Studies have shown that supplementation of adult men with selenium-enriched yeast (SY) rotective against prostate cancer (PCa) and also reduced oxidative stress and levels of prostatec antigen. Here, we determined the effect of SY supplementation on global serum protein expresn healthy men to provide new insights into the mechanism of selenium chemoprevention; such ns may also ...

Although slow and persistent viruses often escape host defenses infection may be prevented by live vaccines. To determine whether an attenuated "slow" strain of the Creutzfeldt-Jakob disease agent (SY) could block expression of a virulent "fast" strain (FU), outbred CD-1 mice were inoculated intracerebrally with low infectious doses of SY and challenged 80 days later with higher doses of FU. Fo...
