The effects of citalopram--the most selective serotonin reuptake inhibitor on the market--on psychopathological symptoms were studied in chronic schizophrenic patients on a stable regimen of neuroleptic medication. Outpatients suffering from schizophrenic disorder (DSM-III-R) with Positive and Negative Symptom Scale (PANSS) scores higher than 50 were(More)
The cross-sectional study assessed the associations among smoking status, number of cigarettes smoked per day, and psychiatric symptoms in 88 chronic schizophrenic outpatients with a stable psychic condition. Among the 49 smokers, the number of cigarettes smoked per day was associated with the severity of cognitive symptoms of the Positive and Negative(More)
OBJECTIVE The effect of smoking on daily doses and plasma levels of neuroleptics prescribed for schizophrenic patients was studied. METHODS 90 outpatients with schizophrenic disorder (DSM-III-R) who were on a stable regimen of psychotropic medication and showed a stable clinical state were included in a double-blind placebo-controlled trial. Data were(More)

RHIC-tested predictions for low-p T and high-p T hadron spectra in nearly central Pb+Pb collisions at the LHC Abstract We study the hadron spectra in nearly central A+A collisions at RHIC and LHC in a broad transverse momentum range. We cover the low-p T spectra using longitudinally boost-invariant hydrodynamics with initial energy and net-baryon number(More)

We present a calculation of thermal photon production i.e. photons from secondary interactions among particles produced in heavy ion collisions at collider energies. This is done within the framework of hydrodynamics. We take into account the lack of chemical equilibrium in QGP. It turns out that main effects from chemical non-equilibrium composition of(More)

We present results on spectra of pions, kaons and (anti)protons from a study of heavy ion collisions using the perturbative QCD + saturation model to calculate the production of initial (transverse) energy and baryon number followed by a hydrodynamic description of the expansion of produced matter. In particular, we study how the hadron spectra and(More)
There is increasing evidence suggesting that symptoms of depression and anxiety may also be associated with serotonergic dysfunction in schizophrenic patients. The effect of the adjuvant selective serotonin reuptake inhibitor citalopram was assessed regarding the symptom dimensions of schizophrenia measured with the Positive and Negative Syndrome Scale(More)
