Animal models of prenatal immune challenge and their contribution to the study of schizophrenia: a systematic review BJMBR
Macêdo,D.S.; Araújo,D.P.; Sampaio,L.R.L.; Vasconcelos,S.M.M.; Sales,P.M.G.; Sousa,F.C.F.; Hallak,J.E.; Crippa,J.A.; Carvalho,A.F..
Prenatal immune challenge (PIC) in pregnant rodents produces offspring with abnormalities in behavior, histology, and gene expression that are reminiscent of schizophrenia and autism. Based on this, the goal of this article was to review the main contributions of PIC models, especially the one using the viral-mimetic particle polyriboinosinic-polyribocytidylic acid (poly-I:C), to the understanding of the etiology, biological basis and treatment of schizophrenia. This systematic review consisted of a search of available web databases (PubMed, SciELO, LILACS, PsycINFO, and ISI Web of Knowledge) for original studies published in the last 10 years (May 2001 to October 2011) concerning animal models of PIC, focusing on those using poly-I:C. The results showed...

Glutamate-N-methyl-D-aspartate receptor modulation and minocycline for the treatment of patients with schizophrenia: an update BJMBR
Chaves,C.; Marque,C.R.; Trzesniak,C.; Machado de Sousa,J.P.; Zuardi,A.W.; Crippa,J.A.S.; Dursun,S.M.; Hallak,J.E..
Growing consistent evidence indicates that hypofunction of N-methyl-D-aspartate (NMDA) transmission plays a pivotal role in the neuropathophysiology of schizophrenia. Hence, drugs which modulate NMDA neurotransmission are promising approaches to the treatment of schizophrenia. The aim of this article is to review clinical trials with novel compounds acting on the NMDA receptor (NMDA-R). This review also includes a discussion and translation of neuroscience into schizophrenia therapeutics. Although the precise mechanism of action of minocycline in the brain remains unclear, there is evidence that it blocks the neurotoxicity of NMDA antagonists and may exert a differential effect on NMDA signaling pathways. We, therefore, hypothesize that the effects of...

Maternal administration of cannabidiol promotes an anti-inflammatory effect on the intestinal wall in a gastroschisis rat model BJMBR
Callejas,G.H.; Figueira,R.L.; Gonçalves,F.L.L.; Volpe,F.A.P.; Zuardi,A.W.; Crippa,J.A.; Hallak,J.E.; Sbragia,L..
Gastroschisis (GS) is an abdominal wall defect that results in histological and morphological changes leading to intestinal motility perturbation and impaired absorption of nutrients. Due to its anti-inflammatory, antioxidant, and neuroprotective effects, cannabidiol (CBD) has been used as a therapeutic agent in many diseases. Our aim was to test the effect of maternal CBD in the intestine of an experimental model of GS. Pregnant rats were treated over 3 days with CBD (30 mg/kg) after the surgical induction of GS (day 18.5 of gestation) and compared to controls. Fetuses were divided into 4 groups: 1) control (C); 2) C+CBD (CCBD); 3) gastroschisis (G), and 4) G+CBD (GCBD). On day 21.5 of gestation, the fetuses were harvested and evaluated for: a) body...

Postural balance in patients with social anxiety disorder BJMBR
Levitan,M.N.; Crippa,J.A.; Bruno,L.M.; Pastore,D.L.; Freire,R.C.; Arrais,K.C.; Hallak,J.E.; Nardi,A.E..
Body stability is controlled by the postural system and can be affected by fear and anxiety. Few studies have addressed freezing posture in psychiatric disorders. The purpose of the present study was to assess posturographic behavior in 30 patients with social anxiety disorder (SAD) and 35 without SAD during presentation of blocks of pictures with different valences. Neutral images consisted of objects taken from a catalog of pictures, negative images were mutilation pictures and anxiogenic images were related to situations regarding SAD fears. While participants were standing on a force platform, similar to a balance, displacement of the center of pressure in the mediolateral and anteroposterior directions was measured. We found that the SAD group...

Psychopharmacotherapy of panic disorder: 8-week randomized trial with clonazepam and paroxetine BJMBR
Nardi,A.E.; Valença,A.M.; Freire,R.C.; Mochcovitch,M.D.; Amrein,R.; Sardinha,A.; Levitan,M.N.; Nascimento,I.; de-Melo-Neto,V.L.; King,A.L.; de O. e Silva,A.C.; Veras,A.B.; Dias,G.P.; Soares-Filho,G.L.; da Costa,R.T.; Mezzasalma,M.A.; de Carvalho,M.R.; de Cerqueira,A.C.; Hallak,J.E.; Crippa,J.A.; Versiani,M..
The objective of the present randomized, open-label, naturalistic 8-week study was to compare the efficacy and safety of treatment with clonazepam (N = 63) and paroxetine (N = 57) in patients with panic disorder with or without agoraphobia. Efficacy assessment included number of panic attacks and clinician ratings of the global severity of panic disorders with the clinical global impression (CGI) improvement (CGI-I) and CGI severity (CGI-S) scales. Most patients were females (69.8 and 68.4% in the clonazepam and paroxetine groups, respectively) and age (mean ± SD) was 35.9 ± 9.6 years for the clonazepam group and 33.7 ± 8.8 years for the paroxetine group. Treatment with clonazepam versus paroxetine resulted in fewer weekly panic attacks at week 4 (0.1 vs...
