After an introduction to chiral perturbation theory, the effective field theory of the standard model at low energies, a brief overview is given of applications to lightflavour physics. Three topics in the strong interactions of pseudoscalar mesons are then discussed in some detail: loops and chiral logs, pion-pion scattering and isospin violation. Lectures given at the Advanced School on QCD 2...

The dairy cow has a well-recognized natural daily pattern of feed intake and milk synthesis, but regulation of these circadian rhythms has not been well described in the literature or well considered in current dairy management. Even when a total mixed ration (TMR) is fed, ruminal fermentation varies due to circadian variation in feed consumption, resulting in more fermentable substrate in the ...

Background: Previous studies have suggested that BRCA1 dysregulation has been shown to have a role in triple-negative phenotypic manifestation. However, differences of BRCA1 expression, as a tumor suppressor gene, have rarely been investigated between luminal and triple-negative breast tumors. Therefore, the present study attempted to compare the BRCA1 expression in triple-negative with lu...

The strategic value of Triple Helix relations of university-government-industry (TH) in creating new knowledge infrastructure and developing the knowledge economy has been widely discussed within the existing innovation and knowledge economy literature. However current research and empirical evidence has been primarily focused on developed countries such as US, Japan and European countries. The...

Using the Keldysh nonequilibrium technique, we study current and the tunnelling magnetoresistance (TMR) in a quantum dot coupled to two ferromagnetic leads (FM-dot-FM). The current is calculated for both parallel and antiparallel lead alignments. Coulomb interaction and spin-flip scattering are taken into account within the quantum dot. Interestingly, we find that these interactions play a cont...

INTRODUCTION: Triple negative cancer is one of the most aggressive subtypes breast cancer. Currently, no effective treatment methods have been proposed that would significantly affect long-term results treatment. OBJECTIVE: To summarize possibilities theranostics and nanteranostics in visualization elimination malignant cells immunosuppressive microenvironment thriple MATERIALS AND METHODS: A s...

The messenger RNAs of human immunodeficiency virus-1 (HIV-1) have an RNA hairpin structure, TAR, at their 5' ends that contains a six-nucleotide loop and a three-nucleotide bulge. The conformations of TAR RNA and of TAR with an arginine analog specifically bound at the binding site for the viral protein, Tat, were characterized by nuclear magnetic resonance (NMR) spectroscopy. Upon arginine bin...

We performed a benchmark study on a series of dihydrogen bond complexes and constructed a set of reference bond distances and interaction energies. The test set was employed to assess the performance of several wave function correlated and density functional theory methods. We found that second-order correlation methods describe relatively well the dihydrogen complexes. However, for high accura...
