Induction of artificial cancer stem cells from tongue cancer cells by defined reprogramming factors

Background The cancer stem cells (CSCs), a small subpopulation of cells in tumor are responsible for the tumor initiation, growth, recurrence and metastasis of cancer, as well as resistance of cancers to drugs or radiotherapy. CSCs are an important target for the development of novel strategies in cancer treatment. However, CSCs-targeted new anti-cancer drug discovery is...

Problems in the Derivations of the Renormalization Group Equation for the Low Momentum Nucleon Interactions

Koji Harada 0 0 Department of Physics, Kyushu University , Fukuoka 810-8560, Japan We carefully examine one of the derivations of the renormalization group equation (RGE) for the so-called Vlow k

Apparently Noninvariant Terms of U(N) × U(N) Nonlinear Sigma Model in the One-Loop Approximation

We show how the Apparently Noninvariant Terms (ANTs), which emerge in perturbation theory of nonlinear sigma models, are consistent with the nonlinearly realized symmetry by employing the Ward-Takahashi identity (in the form of an inhomogeneous Zinn-Justin equation). In the literature the discussions on ANTs are confined to the SU(2) case. We generalize them to the U(N) case and...

Effective Theory Approach to the Skyrme Model and Application to Pentaquarks

The Skyrme model is reconsidered from an effective theory point of view. From the most general chiral Lagrangian up to and including terms of order p4, Nc and δm2 (δm ≡ms − m), new interactions, which have not been previously considered, appear upon collective coordinate quantization. We obtain the parameter set that best fits the observed low-lying baryon masses by carrying out...

Prediction of corticosteroid responsiveness based on fibroblast-specific protein 1 (FSP1) in patients with IgA nephropathy

Background. Corticosteroids are frequently used to treat patients with active IgA nephropathy (IgAN); however, there have been few reports describing factors that are predictive of the response to corticosteroid treatment. The purpose of this study is to determine the extent to which fibroblast-specific protein 1-positive (FSP1+) cells are predictive of corticosteroid...

Revealing the Gauge Freedom in the Path-Integral Formalism

It is proposed that in the path-integral formalism, the gauge freedom is extracted from the vector field and treated independently. This turns out to be a useful device to make theories transparent as can be seen in describing the massive vector theory and the chiral Schwinger model.

A Consistent Gauss Law in Anomalous Gauge Theories

A new Gauss law constraint for anomalous gauge theories, which is defined from the modified action, is proposed. It is then shown in the path-integral framework that this new constraint is consistent, that is, it has no time dependence and no commutator anomalies, thus may be used to define the physical space.
