Altered expression of Twist, matrix metalloproteinase (MMP)-2 and MMP-9 proteins has been identified in various types of human cancers. However, the correlation between Twist and these gelatinases in breast cancer remains unclear. In this study, immunohistochemical analysis of Twist, MMP-2 and MMP-9 expression was performed on tissue microarrays from 200 breast cancer cases. The association of ...

The twisting stage is one of the most important preparatory stages for yarn it begins with Doubling process in preparation giving suitable twists. A twisted formed by together two or more singles yarns. purpose twist Increase specific durability yarn, C.V Production yarns from mixing and Fancy yarn. modern technology was developed process, achieving advantages at technical economic levels, whic...

We present an improved calculation of B → light pseudoscalar formfactors from light-cone sum rules, including one-loop radiative corrections to twist-2 and twist-3 contributions, and leading order twist-4 corrections. The total theoretical uncertainty of our results at zero momentum transfer is 10 to 13% and can be improved, at least in part, by reducing the uncertainty of hadronic input parame...

Epithelial-to-mesenchymal transition (EMT) facilitates tumor metastasis. Twist is a basic helix-loop-helix protein that modulates many target genes through E-box-responsive elements. There are two twist-like proteins, Twist-1 and Twist-2, sharing high structural homology in mammals. Twist-1 was found to be a key factor in the promotion of metastasis of cancer cells, and is known to induce EMT. ...

Properties of the nucleon twist-3 distribution function e(x) are reviewed. It is emphasized that the QCD equations of motion imply the existence of a δ-function at x = 0 in e(x), which gives rise to the pion-nucleon sigma-term. According to the resulting “practical” DIS sum rules the first and the second moment of e(x) vanish, a situation analogue to that of the pure twist-3 distribution functi...

The hadronic decays B → J/ψK(K∗) are interesting because experimentally they are the only color-suppressed modes which have been measured, and theoretically they are calculable by QCD factorization even the emitted meson J/ψ is heavy. We analyze the decay B → J/ψK within the framework of QCD factorization in the heavy quark limit. We show explicitly the scale and γ5-scheme independence of decay...

We consider the Melvin Twist of AdS5×S5 under U(1)×U(1) isometry of the boundary S3 of the global AdS5 geometry and identify its field theory dual. We also study the thermodynamics of the Melvin deformed theory. Melvin twist, also known as the T-s-T transformation, is a powerful solution generating technique in supergravity and string theories [1–6]. The procedure relies on having a U(1)× U(1) ...
