Neurologic soft signs (NSS) are considered a somatic feature associated with schizophrenia (DSM-IV) that are present in neuroleptic-treated, as well as untreated or first-episode patients. The aim of this study was to determine the incidence and severity of NSS in groups of schizophrenic patients treated with either a conventional neuroleptic medication,(More)
BACKGROUND The exact cause of schizophrenia is not known, although several aetiological theories have been proposed for the disease, including developmental or neurodegenerative processes, neurotransmitter abnormalities, viral infection and immune dysfunction or autoimmune mechanisms. Growing evidence suggests that specific cytokines and chemokines play a(More)
It has been suggested that oxidative stress activates various intracellular signaling pathways leading to secretion of a variety of pro-inflammatory cytokines and chemokines. SHP-1 is a protein tyrosine phosphatase (PTP) which acts as a negative regulator of immune cytokine signaling. However, intracellular hydrogen peroxide (H(2)O(2)), generated(More)
OBJECTIVE Due to reported modulatory effects of statins on nitric oxide synthase (NOS) expression, we tested the hypothesis of protective effects of in vivo chronic treatment with rosuvastatin, a novel 3-hydroxy-3-methyl-glutaryl coenzyme A-reductase inhibitor, on ischemia-reperfusion injury, and investigated mechanisms involved. METHODS After 3 weeks of(More)
Recently, astaxanthin (ASTA) studies have focused on several biological functions such as radical scavenging, singlet oxygen quenching, anti-carcinogenesis, anti-diabetic, anti-obesity, anti-inflammatory, anti-melanogenesis, and immune enhancement activities. In this study, we investigated the potential role protective of ASTA, an antioxidant marine(More)
Several studies suggest that nitric oxide (NO) production is reduced in diabetes and that the decrease of NO may be related to the pathogenesis of diabetic endothelial damage. NO synthase (NOS) catalyses the conversion of L-arginine to L-citrulline in the presence of oxygen and NADPH-diaphorase (NADPH-d). In this study, we evaluated the expression of(More)
During ageing, the occurrence of apoptosis is due to a progressive impairment of normal functions, leading to eliminate redundant, damaged or infected cells. Here we report that also in myocardial tissue, ageing, besides reduction of the number of myocytes and of specialized conduction tissue cells, reduction in Ca(++) transport across the membrane,(More)
The genus Glycyrrhiza consists of about 30 species, amoung these, G. glabra is the source of several phenolic compounds, known as flavonoids, such as licoagrodin, licoagrochalcones, licoagroaurone and licochalcone C, kanzonol Y, glyinflanin B and glycyrdione A, which have shown various pharmacological activities, including antitumor, antiparasitic,(More)
The authors used the Scale for Assessment of Negative Symptoms and the Scale for Assessment of Positive Symptoms in interviews of 96 psychiatric inpatients in Italy. They evaluated the interrater reliability and the internal consistency of these scales for the assessment of negative and positive symptoms in schizophrenia. Their findings indicate that the(More)
