It is well known that housing conditions may alter several physiological and behavioral parameters. In this study, we have investigated whether a prolonged period of partial social isolation can modify central brain-derived neurotrophic (BDNF) concentrations. Male Sprague-Dawley rats were singly housed for 8 weeks before hippocampi, prefrontal cortices and(More)
This study was performed to assess the efficacy and safety of docetaxel, cisplatin and fluorouracil combination in patients with unresectable locally advanced oesophageal squamous cell carcinoma. Treatment consisted of docetaxel 60 mg m(-2), cisplatin 75 mg m(-2) on day 1 and fluorouracil 750 mg m(-2) day(-1) on days 2-5, repeated every 3 weeks for three(More)
Brain-derived neurotrophic factor (BDNF) expression in the hippocampus is reduced in response to acute, as well as repeated immobilization stress. This effect might be mediated by corticosterone, because corticosterone administration is known to reduce hippocampal BDNF. However, rats subjected to a learning paradigm showed an increased BDNF expression in(More)
It has been proposed that S100B can be a marker for several pathological conditions including brain traumas, blood-brain barrier disruption, and ischemia. Because the hypothalamo-pituitary-adrenal axis is activated in these conditions, we investigated the role of glucocorticoids in the effects of stress on serum S100B. Restraint stress increased S100B(More)
Epidemiological evidence suggests that adolescents and adults perinatally exposed to alcohol, even at low doses, show high prevalence of cognitive impairment and social behavior deficits, which may be in part related to alcohol-induced changes of the gamma-aminobutyric acid (GABA)ergic neurotransmission. The endogenous neurosteroid(More)
Systemic injection of the mGlu2/3 receptor antagonist, LY341495 (1 mg/kg, i.p.), increased plasma corticosterone in mice to an extent similar to that induced by the despair test. Treatment with the mGlu2/3 receptor agonist, LY379268 (1 mg/kg, i.p.), or the non-competitive mGlu5 receptor antagonist, MPEP (5 mg/kg, i.p.), failed to induce significant changes(More)
When injected intracerebroventricularly (i.c.v.) in rats, nociceptin/orphanin FQ (N/OFQ) delays gastric emptying and increases plasma corticosterone levels. Our aim in this study was to investigate changes in gastric emptying of a phenol red meal, and the plasma corticosterone response to N/OFQ in adrenalectomized (ADX) rats, in ADX rats injected with(More)
Several studies indicate that stress can produce remarkable effects on neurotrophic factors. In this regard, hippocampus is the most interesting structure of the brain because of its broad involvement in behavioral and neuroendocrine phenomena. In the present study, we investigated the effect of stress on hippocampal prosaposin, which is known to act as a(More)
The use of antagonists of N-methyl-D-aspartate (NMDA) receptors, or the administration of inhibitors of the synthesis or of the release of excitatory amino acids, enables the analgesic drug-dependence associated with chronic daily migraine to be overcome without any physical abstinence sign. Follow-up period indicates that negative modulators of excitatory(More)
BACKGROUND Auto-crosslinked polysaccharide hyaluronan-based solution (Hyalobarrier-gel) prevents postoperative adhesions. However, its effect on tumour growth is still unknown. The aim of the present study was therefore to investigate the impact on survival of intra-abdominally administered Hyalobarrier-gel, native hyaluronan (HA) and(More)
