The walkability planning support system: An evidence-based tool to design healthy communities

A major challenge for all cities is to reconcile growth with cultural, social and environmental considerations, along with connecting urban design with opportunities for health and wellbeing. Planning Support Systems (PSSs) can facilitate future planning and foster collaboration between researchers and urban planners in promoting healthy built environments. The Walkability PSS was developed specially for that purpose. This chapter presents an evaluation of the Walkability PSS, a PSS for building planning scenarios and assessing their impacts on walking behaviours. The evaluation was conducted in collaboration with a group of local urban planners. The study results show that the Walkability PSS could support planners in several situations including testing and comparing planning scenarios for greenfield and brownfield areas, conducting consultation and/or workshops with various stakeholders and making decisions about the provision of new infrastructure

Trypanosoma congolense: Proliferative responses and interleukin production in lymph node cells of infected cattle

T-cell-mediated immune responses to defined antigens of Trypanosoma congolense were measured in cattle undergoing primary infection. The antigens used were the variable surface glycoprotein and two invariant antigens, a 33-kDa cysteine protease (congopain) and a recombinant form of a 69-kDa heat-shock protein. Proliferative responses were highest during the second week postinfection and were detected in cells obtained from the lymph node draining the site of infection but not in peripheral blood mononuclear cells. Production of IL-2 and IFN- was measured in supernatants from antigen-stimulated lymph node cell cultures. Expression of IL-2, IL-4, and IFN- mRNA was detected in antigen-stimulated lymph node cells by reverse transcription-polymerase chain amplification
