Glass-liquid and glass-gel transitions of soft-shell particles.

We study the structure and dynamics of colloidal particles with a spherical hard core and a thermo-responsive soft shell over the whole phase diagram by means of small-angle x-ray scattering and x-ray photon correlation spectroscopy. By changing the effective volume fraction by temperature and particle concentration, liquid, repulsive glass. and attractive gel phases are observed.

The state-trait anxiety inventory, trait version: does it really measure anxiety?

To clarify what is actually measured by the trait version of the State-Trait Anxiety Inventory (STAI; Spielberger, Gorsuch, & Lushene, 1970), we conducted a confirmatory factor analysis of various models and evaluated convergent and discriminant validity. The best fit was obtained with both a bifactor model, comprising 2 specific factors plus a general factor, and a 1-construct, 2-method model. The total score and the 2 method subscales of the STAI trait version were more strongly correlated with depression than with anxiety.

Outcome of cognitive-behavioural therapy in training practice with anxiety disorder patients.

Objectives: This study aims to assess the effectiveness of cognitive-behavioural therapy applied by trainee therapists in patients with anxiety disorders seen in a private university service and to examine whether this effectiveness is comparable to that observed in controlled studies.

Design: We compared the effectiveness of cognitive-behavioural therapy at a private centre with that observed in meta-analyses and reviews of controlled studies.

Methods: Out of the 96 initial patients with anxiety disorder, 64 completed the cognitive-behavioural treatment and 59 also answered a series of questionnaires pre- and post-treatment.

The efficacy of cognitive-behavioral therapy and the problem of drop-out.

Treatment drop-out is a common problem in the everyday practice of psychotherapy. In the cognitive-behavioral psychology literature, there are scant data on drop-out from therapy and the data available vary widely according to the definition of drop-out and the intensity of treatment. This study presents results obtained in the Behavioural Therapy Unit of the University of Barcelona.

Effect of oral calcidiol treatment on its serum levels and peritoneal losses.

Objectives: To evaluate calcidiol serum levels in a group of continuous ambulatory peritoneal dialysis (CAPD) patients and the effect of oral calcidiol treatment on serum levels and peritoneal losses.

Study Design: Twenty patients (13 female, 7 male) were studied for 12-60 months. Their ages ranged 22-72 years (mean 46 +/- 15).
