PTEN is a tumor suppressor gene mutated in many human cancers. We generated a bronchioalveolar epithelium-specific null mutation of Pten in mice [SP-C-rtTA/(tetO)(7)-Cre/Pten(flox/flox) (SOPten(flox/flox)) mice] that was under the control of doxycycline. Ninety percent of SOPten(flox/flox) mice that received doxycycline in utero [SOPten(flox/flox)(E10-16) mice] died of hypoxia soon after birth....
In the developing brain, differentiation of neural precursors into neurons or glial cells occurs in response to neurotrophic factors acting on the cell surface. Intracellular signaling mechanisms that relay information to initiate differentiative responses of neural precursor cells are poorly understood. To investigate whether stimulation of the cAMP-dependent signaling pathway participates in ...
The present work carries out an experimental comparative analysis of the performance and emission exhaust gases Otto cycle with four automotive times. comparison was made between alternative fuels such as E10, E15, E20, both 90 95 octane each commercialized fuel. tests were carried engine load corresponding to 25% maximum load. After carrying tests, following conclusions can be reached: on effe...
We propose that the structure of gauge theories, the (2, 0) and little-string theories is encoded in a unique function on the real group manifold E10(R). The function is invariant under the maximal compact subgroup K acting on the right and under the discrete U-duality subgroup E10(Z) on the left. The manifold E10(Z)\E10(R)/K contains an infinite number of periodic variables. The partition func...
The structure of the general, inhomogeneous solution of (bosonic) Einstein-matter systems in the vicinity of a cosmological singularity is considered. We review the proof (based on ideas of BelinskiiKhalatnikov-Lifshitz and technically simplified by the use of the ArnowittDeser-Misner Hamiltonian formalism) that the asymptotic behaviour, as one approaches the singularity, of the general solutio...
We review the finding that the general solution of many physically relevant (bosonic) Einstein-matter systems in the vicinity of a cosmological, i.e. space-like, singularity exhibit a remarkable mixture of chaos and symmetry. On the one hand, the asymptotic behavior, as one approaches the singularity, of the general solution is found to be describable, at each (generic) spatial point, as a bill...
We review the recently discovered interplay between chaos and symmetry in the general inhomogeneous solution of many string-related Einstein-matter systems in the vicinity of a cosmological singularity. The Belinsky-Khalatnikov-Lifshitz-type chaotic behaviour is found, for many Einstein-matter models (notably those related to the low-energy limit of superstring theory andM-theory), to be connec...
