[Early detection of mental health disorders at school: The Fil Harmonie pilot program].

Objective: Most psychiatric disorders arise during adolescence, a period of life during which school takes an important place. School in France has an official mission of health education and prevention, and early detection of mental disorders is part of these goals. The aim of this study is to describe an innovative service operating in Paris that helps educational staff to deal with students having psychological or psychiatric symptoms.

Computerized ambulatory monitoring in mood disorders: feasibility, compliance, and reactivity.

Patients with depression (n=20) or bipolar disorder (n=21) completed computerized ambulatory monitoring for three consecutive days. Results indicate satisfactory rates of acceptance and compliance, with no salient fatigue effects. However, some evidence for reactive effects was found.

Corticosteroid-binding globulin synthesis regulation by cytokines and glucocorticoids in human hepatoblastoma-derived (HepG2) cells.

Plasma corticosteroid-binding globulin (CBG) concentrations decrease dramatically in patients with septic shock or burn injury. This decrease suggests that mediators of the acute phase response, such as cytokines and glucocorticoid hormones, might influence clearance as well as liver synthesis of CBG in humans. The present study investigated the effects of interleukin-6 (IL-6), IL-1 beta, and dexamethasone on CBG synthesis by a clone of human hepatoblastoma-derived (HepG2) cell line.

Differential effects of insulin and insulin-like growth factor I on the production of plasma steroid-binding globulins by human hepatoblastoma-derived (Hep G2) cells.

Changes in the plasma levels of corticosteroid-binding globulin (CBG) and sex hormone-binding globulin (SHBG) from birth to adulthood suggest that growth factors might influence clearance and/or hepatic secretion of CBG and SHBG in humans. The effects of insulin-like growth factor I (IGF-I) and insulin on CBG and SHBG synthesis by a clone of human hepatoblastoma-derived (Hep G2) cell lines were therefore investigated. The results showed that the immunoconcentrations of CBG and SHBG, as well as total protein concentration in culture medium from Hep G2 cells, were decreased by IGF-I and insulin.

Decreased immunoreactivity and binding activity of corticosteroid-binding globulin in serum in septic shock.

To investigate the mechanism(s) responsible for the depletion of corticosteroid-binding globulin (CBG) activity in serum in septic shock, we developed a radioimmunoassay (RIA) for human CBG, using a monospecific antiserum to human CBG raised in rabbits. CBG was purified from pooled human serum by precipitation with ammonium sulfate and successive affinity chromatography treatments on corticosterone-Sepharose and concanavalin A-Sepharose. Final purification was achieved by HPLC on a diethylaminoethyl-PW (polymer matrix) ion-exchange column.
