Role of 2p-2h MEC excitations in superscaling
Following recent studies of inclusive electron scattering from nuclei at high
energies which focused on two-nucleon emission mediated by meson-exchange
currents, in this work the superscaling behavior of such contributions is
investigated. Comparisons are made with existing data below the quasielastic
peak where at high momentum transfers scaling of the second kind is known to be
excellent and scaling of the first kind is good, in the proximity of the peak
where both 1p-1h and 2p-2h contributions come into play, and above the peak
where inelasticity becomes important and one finds scaling violations of the
two kinds.Comment: 27 pages, 12 figures; references adde

Leptin inhibits stress-induced apoptosis of T lymphocytes
Leptin, which is secreted by adipocytes, the placenta and the stomach, not only controls appetite through leptin receptors in the hypothalamus but also regulates cell-mediated immunity. In this study we have demonstrated that continuous injection of leptin prevents the reduction in lymphocyte numbers normally observed in fasted and steroid-injected mice. Consistent with leptin-induced protection, we observed up-regulation of the bcl-xL gene as a result of signal transduction via leptin receptors on lymphocytes. We suggest that leptin might contribute to the recovery of immune suppression in malnourished mice by inhibiting lymphocyte apoptosis
