Reduced Satb1 expression predisposes CD4 T conventional cells to Treg suppression and promotes transplant survival.

Limiting CD4 T cell responses is important to prevent solid organ transplant rejection. In a mouse model of costimulation blockade-dependent cardiac allograft tolerance, we previously reported that alloreactive CD4 conventional T cells (Tconvs) develop dysfunction, losing proliferative capacity. In parallel, induction of transplantation tolerance is dependent on the presence of regulatory T cells (Tregs).

[Assessment of the clinical activity of fluoxetin (Prozac) according of the "Stars of Liège" model].

Ten psychiatrists have independently rated the clinical profile of fluoxetin (Prozac) at the daily dose of 20 mg according to a "Stars of Liège" model comprising three parameters of therapeutic activity (antidepressant, psychostimulant and anxiolytic) and three parameters of side-effects (anticholinergic, sedative and hypotensive). Each parameter, graduated from 0 to 5 (no, very weak, weak, moderate, potent, very potent effect) was rated by each investigator according to his personal experience with at least 10 patients. Mean ratings given to fluoxetine show a moderate antidepressant effect, equal to amitriptyline (Rédomex, Tryptizol 75 mg/d, clomipramine (Anafranil 75 mg/d and nialamide (Niamide 100 mg/d, weak psychostimulating and anxiolytic effects, a very weak sedative effect and a lack of anticholinergic and hypotensive effects.

[Novel comparative profile of the clinical activity of antidepressive agents].

In order to develop practical criteria to guide in the selection of antidepressant medication according to depressive symptomatology, we propose a graphical representation of the clinical activity of 24 antidepressants according to a "star" model. Six parameters have been evaluated from 0 to 5 in comparison to reference drugs (rated 5) by 11 independent "blind" psychiatrists expert in pharmacotherapy. Three parameters were used as measures of therapeutic activity: antidepressant, psychostimulant, and anxiolytic, with iproniazide 75 mg/d, metamphetamine 15 mg/d, and diazepam 20 mg/d as reference drugs respectively.

[Clinical comparison between alprazolam and lorazepam. A polycentric study in double blind].

The clinical efficacy and safety of alprazolam was compared to lorazepam in a double blind randomized design involving 82 out-patients suffering from primary anxiety. Seventy four patients (37 on alprazolam and 37 on lorazepam) were evaluable. They were treated with a flexible dose of 0,75 mg to 3 mg of alprazolam per day (average final dose: 1,59 mg) or 3 mg to 12 mg of lorazepam per day (average final dose: 5,97 mg).
