1. The transmural electrical potential difference (PD) of the intact human small intestine was recorded with close attention to electrical symmetry, shielding from electro-magnetic waves and correction for junction potentials. 2. The PD is -12 mV (mucosa-negative) in the fasting jejunum and ileum and does not change during perfusion with isotonic NaCl. 3.(More)
Background The evaluation of the interaction of new immunogens with dendritic cells is important for new vaccine strategies. We used polylactic acid (PLA) colloidal biodegradable particles, coated with HIV Gag antigens (p24), and Modified Vaccinia Ankara (MVA) expressing Gag or Tat, Nef and Rev in an ex vivo model of human monocyte-derived dendritic cells(More)
We will discuss several recent advances in agent-based modeling, with applications to mass egress and wide-area evacuations following disasters. These advances include: efficiency improvements in specifying people's identification and selection of exit routes, making it possible to handle up to 70,000 people-agents; incorporation of new crowd movement(More)
