    Notes: Summary A method for the separation and purification of bacteroids and mitochondria from nodules of soybean roots is described. Cross contamination between these two oxidative fractions was easily assessible by using NADH oxidase and β-hydroxybutyrate dehydrogenase respectively as specific mitochondrial and bacteroid markers. Bacteroid respiration was characterized by substantial endogenous respiration which could be reduced by keeping plants in the dark prior to isolation, and stimulated by uncoupler or organic acids. Nodule mitochondria readily oxidized external NADH and a range of tricarboxylic acid cycle intermediates, with good respiratory control. A major difference between nodule and root mitochondria was the former's high sensitivity to the inhibitors rotenone and cyanide. This indicates a reduced capacity for non-phosphorylating electron transport in nodule mitochondria, which may be related to the large energy demand during ammonia assimilation in nodule cells.

    A material isolated from human hands that attracts female mosquitoes (1982)
    Springer
    Journal of chemical ecology 8 (1982), S. 429-438 
    Details
    ISSN: 1573-1561
    Keywords: Attractants ; human ; mosquito ; collection ; concentration ; Aedes aegypti ; Anopheles quadrimaculatus ; Diptera ; Culicidae

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The residue left on glass surfaces by human hands was found to be attractive to femaleAedes aegypti (L.) andAnopheles quadrimaculatus Say mosquitoes. The material lost half of its activity in 1 hr. A solvent wash technique was developed to recover and concentrate the residuum from handled glass beads. The residuum could be recovered effectively with absolute ethanol and less effectively with several other solvents. More mosquitoes were attracted to heated than to unheated residuum, an indication of its volatility. Also, attraction of the residuum decreased with decreasing concentration or dose. Concentrated residuum collections, stored under refrigeration and tested for longevity, showed no appreciable loss of attractiveness up to 60 days of storage.
