Glioblastoma (GBM) is the most malignant brain tumor and is highly resistant to intensive combination therapies and anti-VEGF therapies. To assess the resistance mechanism to anti-VEGF therapy, we examined the vessels of GBMs in tumors that were induced by the transduction of p53(+/-) heterozygous mice with lentiviral vectors containing oncogenes and the marker GFP in the hippocampus of GFAP-Cr...
D-Xylose-based ionic liquids have been prepared from D-xylose following a five steps reaction sequence, the key step being a click cycloaddition. These ionic liquids (ILs) have been characterized through classical analytical methods (IR, NMR, mass spectroscopy, elemental analysis) and their stability constants, Tg and Tdec, were also determined. Considering their properties and their hydrophili...
Advances in display and camera technology enable new applications for three-dimensional (3D) scene communication, such as 3DTV. 3D Multi-view video contains a large amount of inter-view statistical dependencies, since all cameras capture the same scene from different viewpoints. Due to the vast raw bit rate, multi-view video data are expected to consume a large portion of available bandwidth. T...
Recent observational and theoretical studies have raised the possibility that the collimated outflows in gamma-ray burst (GRB) sources have two distinct components: a narrow (opening half-angle θj,n), highly relativistic (initial Lorentz factor ηn & 10 ) outflow, from which the γ-ray emission originates, and a wider (θj,w . 3 θj,n), moderately relativistic (ηw ∼ 10) surrounding flow. Using a si...
A Schrödinger cat state is a linear superposition of two quantum states that differ on a macroscopic scale. Whereas superpositions of quantum states are commonplace in the microscopic world, a superposition of macroscopically distinct states is practically never observed. The understanding of why this is so has evolved considerably with the development of the quantum mechanics of dissipative sy...
We study the hadron spectra in nearly central A+A collisions at RHIC and LHC in a broad transverse momentum range. We cover the low-pT spectra using longitudinally boost-invariant hydrodynamics with initial energy and net-baryon number densities from the perturbative QCD (pQCD)+saturation model. Build-up of the transverse flow and sensitivity of the spectra to a single decoupling temperature Td...
Although there is abundant evidence that 1alpha,25-dihydroxyvitamin D(3) [1,25-(OH)(2)D(3)] inhibits the growth of several cancer cell types, inhibition of angiogenesis may also play a role in mediating the antitumor effects of 1,25-(OH)(2)D(3.) We examined the ability of 1,25-(OH)(2)D(3) to inhibit the growth of tumor-derived endothelial cells (TDECs) and normal endothelial cells and to modula...
In the State of Tennessee, the Tennessee Department of Environment and Conservation (TDEC) is the NPDES permitting authority who sets color limits for a recreational water use color narrative under the auspices of EPA review that requires effluent discharge to be free of objectionable color, but the narrative lacks numeric guidance on how to determine an acceptable discharge color. The City of ...
We systematically analyze the prompt emission and the early afterglow data of a sample of 31 GRBs detected by Swift before September 2005, and estimate the GRB radiative efficiency. BAT’s narrow band inhibits a precise determination of the GRB spectral parameters, and we have developed a method to estimate these parameters with the hardness ratio information. The shallow decay component commonl...
