The periplasmic component of the DctPQM TRAP-transporter is part of the DctS/DctR sensory pathway in .

can use C4-dicarboxylic acids to grow heterotrophically or photoheterotropically, and it was previously demonstrated in that the DctPQM transporter system is essential to support growth using these organic acids under heterotrophic but not under photoheterotrophic conditions. In this work we show that in this transporter system is essential for photoheterotrophic and heterotrophic growth, when C4-dicarboxylic acids are used as a carbon source. We also found that over-expression of is detrimental for photoheterotrophic growth in the presence of succinic acid in the culture medium.

"A computer isn't gonna judge you": a qualitative study of users' views of an internet-based cognitive behavioural guided self-care treatment package for bulimia nervosa and related disorders.

Little is known about what determines uptake and acceptability of internet-based treatments in eating disorders, and users' experience with such treatments. We investigated these factors in participants of a randomized controlled trial of an internet-based cognitive- behavioural treatment (iCBT) package (Overcoming bulimia online). Nine participants were interviewed using purposive sampling.

The role of email guidance in internet-based cognitive-behavioural self-care treatment for bulimia nervosa.

Email has been progressively used as a means for providing therapeutic guidance and support for cognitive behavioural treatment (CBT) self-care programmes. Many aspects of the use of email in self-care need to be explored such as the content of therapists' emails. Such information would optimise the delivery of self-care treatments.

A randomized controlled trial of internet-based cognitive-behavioural therapy for bulimia nervosa or related disorders in a student population.

Background: Bulimic eating disorders are common among female students, yet the majority do not access effective treatment. Internet-based cognitive-behavioural therapy (iCBT) may be able to bridge this gap.

Method: Seventy-six students with bulimia nervosa (BN) or eating disorder not otherwise specified (EDNOS) were randomly assigned to immediate iCBT with e-mail support over 3 months or to a 3-month waiting list followed by iCBT [waiting list/delayed treatment control (WL/DTC)].
