kant’s ethical theory is one the most important theories in philosophy of ethics, which has always attracted the attention of the commentators and critics. although it has many positive points, there are some objections to this theory just as to any other human theory. in this article, it is attempted to point out the critiques that seem to have been leveled against kant’s ethics. some of these...

objectives : squamous cell carcinoma (scc) is the most common malignant neoplasm of the oral cavity and a public health threat. tumor progression is believed to be influenced by angiogenesis as well as tumor cell proliferation; however, the correlation of these two factors in tongue scc still remains unclear. this study aimed to assess the correlation of these two factors in tongue scc. materia...

background: angiogenesis gene therapy has long been sought as a novel alternative treatment for restoring the blood flow and improving the contractile function of the ischemic heart in selected clinical settings. angiogenic fibroblast growth factor-1 (fgf-1) is a promising candidate for developing a promising gene therapy protocol due to its multipotent ability to stimulate endothelial cell (ec...

A new, non-invasive method for measuring reserpine-induced tremor in rodents is described here. The test procedure is based on the piezo-electric principle and was evaluated using the tremorogenic compound reserpine and the stereotypies-inducing drug apomorphine. Whereas for reserpine an orderly and dose-related increase in activity was observed, no such effect was detected with apomorphine. In...

Spacetime foam can be modeled in terms of nonlocal effective interactions in a classical nonfluctuating background. Then, the density matrix for the low-energy fields evolves, in the weak-coupling approximation, according to a master equation that contains a diffusion term. Furthermore, it is argued that spacetime foam behaves as a quantum thermal field that, apart from inducing loss of coheren...

In this talk we show how Lorentz invariance violation (LIV) can occur for Majorana neutrinos, without inducing LIV in the charged leptons via radiative corrections. Such “electrophobic” LIV is due to the Majorana nature of the LIV operator together with electric charge conservation. Being free from the strong constraints coming from the charged lepton sector, electrophobic LIV can in principle ...

The mesoderm of amphibian embryos arises through an inductive interaction in which a signal from the vegetal hemisphere of the blastula-stage embryo acts on overlying equatorial cells. Strong candidates for endogenous mesoderm-inducing signals include members of the fibroblast growth factor (FGF) and activin families. In this paper we show that cells form different mesodermal cell types in resp...
