Immunological adjuvants, such as bacterial LPS, increase the mRNA levels of the IkB-related NF-kappaB transcriptional transactivator, Bcl-3, in activated T cells. Adjuvants also increase the life expectancy of activated T cells, as does over-expression of Bcl-3, suggesting that Bcl-3 is part of the pathway whereby adjuvants affect T cell lifespans. However, previous reports, confirmed here, sho...

We study the top quark decay to b quark and W boson in the NonCommutative Standard Model (NCSM). The lowest contribution to the decay comes from the terms quadratic in the matrix describing the noncommutative (NC) effects while the linear term is seen to identically vanish because of symmetry. The NC effects are found to be significant only for low values of the NC characteristic scale. PACS:11...

In recent years the high and ultra-high magnetic field MRI scanners have started to leave the confinement of specialized and research oriented laboratories and progressively are entering the clinical use. There are several reasons to justify the progressive increase of the field such as better quality of images that is better spatial resolution, better signal to noise and contrast to noise rati...

The optimum parameters for single-shot gradient-recalled (GR) EPI-based fMRI studies of the limbic region are systematically established at 3 T via their ability to mitigate intravoxel dephasing-measured via SNR and T2* in the amygdalae-and their implications for temporal resolution (or brain coverage). Conventional imaging parameters (64 x 64 matrix size and 4-6 mm thick slices) are confirmed ...
