In research projects based on questions which emerge from practice and from interactions with different stakeholders, researchers engage with research partners in a cooperative and interdisciplinary approach. In PhD projects, including a diverse network of partners and interdisciplinarity may be challenged by the short duration of the projects and by the positivist and reductionist approaches in which students are initially trained. Based on a concrete PhD research project on small-scale organic seed production, the objective of this work is to elucidate how interdisciplinarity and an action-base can nevertheless gradually be integrated by PhD students into an approach best termed as involved research. Reflection on the roles of partners, their involvement, motivation and points of view and on the evolution of questions posed during interactions between students and stakeholders contributes to recognizing the role of each partner, situating research postures, and identifying the types of knowledge and transformations produced. While PhD students and their research projects can evolve towards more holistic and constructivist approaches, it is crucial to maintain opportunities for reflection during their research in order to realize the potentials of involving all those involved in the projects and produce effective social learning processes.

The involvement of bradykinin, 5-hydroxytryptamine, substance P and prostanoids in the hyperalgesia elicited by collagenase in rat paw was investigated. Collagenase (100 micrograms) induced a slight hyperalgesia in kininogen deficient rats in comparison with the behavioural response obtained in normal rats. Lisinopril (10(-5) M), and angiotensin-converting enzyme inhibitor, increased the duration of the hyperalgesia elicited in normal rats. Ondansetron (0.5 to 5 mumol/kg), a 5-HT3 antagonist, suppressed the hyperalgesia as did methysergide (1.1 to 11 mumol/kg), a mixed 5-HT1 and 5-HT2 receptor antagonist. However, the hyperalgesia was not modified by RP 67580 (1.8 to 18 mumol/kg), a NK1 receptor antagonist, and was only slightly delayed by indomethacin (2 mg/kg), a cyclo-oxygenase inhibitor. The oedema-promoting effect of 5-HT (6 nmol) was inhibited by methysergide but not by ondansetron. The swelling induced by collagenase in rat paw was reduced by methysergide but not by ondansetron. We conclude that the behavioural response induced by collagenase depends on an interactions between bradykinin and 5-HT. Prostanoids play a minor role in the beginning of the reaction whereas substance P is not significantly involved in this hyperalgesia. [less ▲]

We reported previously on the function of acyl coenzyme A (acyl-CoA) oxidase isozymes in the yeast Yarrowia lipolytica by investigating strains disrupted in one or several acyl-CoA oxidase-encoding genes (POX1 through POX5) (H. Wang et al., J. Bacteriol. 181:5140-5148, 1999). Here, these mutants were studied for lactone production. Monodisrupted strains produced similar levels of lactone as the wild-type strain (50 mg/liter) except for Δpox3, which produced 220 mg of γ-decalactone per liter after 24 h. The Δpox2 Δpox3 double-disrupted strain, although slightly affected in growth, produced about 150 mg of lactone per liter, indicating that Aox2p was not essential for the biotransformation. The Δpox2 Δpox3 Δpox5 triple- disrupted strain produced and consumed lactone very slowly. On the contrary, the Δpox2 Δpox3 Δpox4 Δpox5 multidisrupted strain did not grow or biotransform methyl ricinoleate into γ-decalactone, demonstrating that Aox4p is essential for the biotransformation.

This PET study explored the neural substrate of both dual-task management and integration task using single tasks that are known not to evoke any prefrontal activation. The paradigm included two simple (visual and auditory) discrimination tasks, a dual task and an integration task (requiring simultaneous visual and auditory discrimination), and baseline tasks (passive viewing and hearing). Data were analyzed using SPM99. As predicted, the comparison of each single task to the baseline task showed no activity in prefrontal areas. The comparison of the dual task to the single tasks demonstrated left-sided foci of activity in the frontal gyrus (BA 9/46, BA 10/47 and BA 6), inferior parietal gyrus (BA 40), and cerebellum. By reference to previous neuroimaging studies, BA 9/46 was associated with the coordinated manipulation of simultaneously presented information, BA 10/47 with selection processes, BA 6 with articulatory rehearsal, and BA 40 with attentional shifting. Globally similar regions were found for the integration task, except that the inferior parietal gyrus was not recruited. These results confirm the hypothesis that the left prefrontal cortex is implicated in dual-task performance. Moreover, the involvement of a parietal area in the dual task is in keeping with the hypothesis that a parieto-frontal network sustains executive functioning. [less ▲]

In this work, the potential of Bacillus subtilis strain M4 at protecting plants against fungal diseases was demonstrated in different pathosystems. We provide evidence for the role of secreted lipopeptides, and more particularly of fengycins, in the protective effect afforded by the strain against damping-off of bean seedlings caused by Pythium ultimum and against gray mold of apple in post-harvest disease. This role was demonstrated by the strong biocontrol activity of lipopeptide-enriched extracts and through the detection of inhibitory quantities of fengycins in infected tissues. Beside such a direct antagonism of the pathogen, we show that root pre-inoculation with M4 enabled the host plant to react more efficiently to subsequent pathogen infection on leaves. Fengycins could also be involved in this systemic resistance-eliciting effect of strain M4, as these molecules may induce the synthesis of plant phenolics involved in or derived from the defense-related phenylpropanoid metabolism. Much remains to be discovered about the mechanisms by which Bacillus spp suppress disease. Through this study on strain M4, we reinforce the interest in B. subtilis as a pathogen antagonist and plant defense-inducing agent. The secretion of cyclic fengycin-type lipopeptides may be tightly related to the expression of these two biocontrol traits. [less ▲]

The yeast Yarrowia lipolytica produces an extracellular lipase encoded by the LIP2 gene. However, very little is known about the mechanisms controlling its expression, especially on glucose media. In this work, the involvement of hexokinase Hxk1 in the glucose catabolite repression of LIP2 was investigated in a lipase overproducing mutant less sensitive to glucose repression. This mutant has a reduced capacity to phosphorylate hexose compared with the wild-type strain, but no differences could be observed between the HXK1 sequences in the two isolates. This suggested that the reduced phosphorylating activity of the mutant strain probably resulted from a modification in the level of HXK1 expression. However, overexpression of the HXK1 gene in this mutant led to a decrease of both LIP2 induction and extracellular lipase activity, suggesting that the hexokinase is involved in the glucose catabolite repression of LIP2 in Y lipolytica.
