This case report provides an overview of the psychometric properties and clinical utility of the My Vocational Situation (MVS) instrument. The accompanying hypothetical case description illustrates how clinicians could use the MVS to evaluate vocational preferences and outcomes and how the MVS can be used to inform treatment planning and rehabilitation decision making. The information contained in this report is intended to familiarize clinicians with the administration and scoring of the MVS, the psychometric information necessary to interpret results obtained from the MVS, and how the results could be used to provide comprehensive, patient-centered care.

A high-flux region, 5mm from the root tips of seedlings of coastal Douglas-fir (Pseudotsuga menziesii), soybean (Glycine max), zucchini (Cucurbita pepo) and pea (Pisum sativum), was monitored using a microelectrode ion flux measurement system, for changes in the net fluxes of H(+), NH(4)(+) and NO(3)(-) in response to shoot removal. In all species, careful excision of the seedling shoot had no significant effect on the net fluxes of H(+), NH(4)(+) or NO(3)(-) measured 5mm from the root tip. Experiments were carried out for up to 80min after shoot removal, and no temporal interactions were noted.

Nepenthes pitcher plant species differ in their prey capture strategies, prey capture rates, and pitcher longevity. In this study, it is investigated whether or not interspecific differences in nutrient sequestration strategy are reflected in the physiology and microstructure of the pitchers themselves. Using a non-invasive technique (MIFE), ion fluxes in pitchers of Nepenthes ampullaria Jack, Nepenthes bicalcarata Hook.

The effect of pH on nitrate and ammonium uptake in the high-affinity transport system and low-affinity transport system ranges was compared in two conifers and one crop species. Many conifers grow on acidic soils, thus their preference for ammonium vs nitrate uptake can differ from that of crop plants, and the effect of pH on nitrogen (N) uptake may differ. Proton, ammonium and nitrate net fluxes were measured at seedling root tips and 5, 10, 20 and 30 mm from the tips using a non-invasive microelectrode ion flux measurement system in solutions of 50 or 1500 microM NH(4)NO(3) at pH 4 and 7.

Improved vaccines and therapies for virulent poxvirus infection are required, particularly in the light of recent threats of bioterrorism. Cidofovir (HPMPC) is an acyclic nucleoside analog with proven efficacy against poxviruses. Here, we evaluated HPMPC in mice given a recombinant ectromelia virus (ECTV) encoding interleukin-4 (ECTV-IL-4) that is highly immune suppressive.
