question:
Islet function is regulated by islet autonomic nerves. These nerves harbour not only the classical neurotransmitters, acetyl choline and noradrenaline, but also neuropeptides. This study examined whether the neuropeptides, pituitary adenylate cyclase activating polypeptide (PACAP) and gastrin releasing polypeptide (GRP) contribute to the regulation of insulin secretion in model experiments by using receptor gene deleted mice.', 'Anaesthetized mice with genetic deletion of one of the PACAP receptors (PAC1 receptors) or one of the GRP receptors (GRP receptor) or their wildtype counterparts were given glucose through a gastric gavage (150 mg) or intravenously (0.25, 0.50 or 1 g/kg). Blood samples were taken regularly during the following 120 min (after gastric glucose) or at 1 min (after intravenous glucose) for analysis of glucose and insulin.', 'The insulin response to gastric glucose was suppressed by 66% in PAC1 receptor gene deleted mice in association with impaired glucose elimination, whereas the insulin response to intravenous glucose was impaired by 36% only. The insulin response to glucose was suppressed in GRP receptor gene deleted mice by 24% together with impaired glucose elimination, whereas the insulin response to intravenous glucose was not significantly suppressed.
answer:
Is the insulin response to gastric glucose reduced in PAC1 and GRP receptor gene deleted mice?

question:
Neurotensin-1 (NT1) receptor agonists have been proposed as putative antipsychotic drugs. Recently, brain-penetrating NT analogs produced by stability-enhancing modification of the smallest NT fragment, NT(8-13), have demonstrated antipsychotic-like efficacy after acute systemic injection in several preclinical animal tests predictive for antipsychotic efficacy. However, the evidence regarding the persistence versus tolerance of these effects after repeated administration is ambiguous. Previous studies have used compounds that nonselectively activated both NT1 and NT2 receptors or used continuous slow, central infusion of doses rather than daily acute administration, both factors which may have contributed to the ambiguity in the literature regarding the emergence of tolerance.', 'To determine if tolerance develops to the antipsychotic-like effects of NT1 receptor agonists, we investigated the effects of subchronic daily systemic administration of PD149163, a brain-penetrating NT analog with selectivity for the NT1 receptor, on amphetamine-induced locomotor activation, a classic preclinical test of antipsychotic efficacy.', 'Sprague-Dawley rats were pretreated with eight consecutive daily subcutaneous (SC) injections of PD149163 or saline. On the ninth day, rats received a pair of SC injections consisting of PD149163 or saline, followed by amphetamine (0.5 mg/kg) or saline. Locomotor activity was then measured in photobeam-equipped cages.', "The results indicated that repeated daily administration of PD149163 was able to antagonize amphetamine's locomotor-activating effect comparable to that of the first dose, despite that repeated administration of PD149163 produced an increase in baseline locomotor activity not seen after the first dose.
answer:
Does the reversal of amphetamine-induced locomotor activation by a selective neurotensin-1 receptor agonist exhibit tolerance?

question:
The assessment of outcome in schizophrenic patients should consider both the response to treatment and the recovery of social skills. The aim was to evaluate the outcome and related psychostructural and clinical factors in schizophrenic patients after they underwent 6 months of residential multimodal treatment.', 'Fifty-two schizophrenic patients enrolled in a multimodal treatment program were included in the study. Symptomatology and social functioning were assessed with the Brief Psychiatric Rating Scale (BPRS) and the Social and Occupational Functioning Assessment Scale (SOFAS). The Karolinska Psychodynamic Profile (KAPP) was used for the psychostructural evaluation.', 'After 6 months there was a significant improvement in the global scores of BPRS, SOFAS, and some areas of KAPP. The personality (KAPP) and social-occupational functioning (SOFAS) at baseline (T0) correlated with the global score of BPRS at 6 months (T6); moreover, SOFAS at T6 correlated with BPRS and KAPP at T0 and with the illness duration.
answer:
Does baseline personality functioning correlate with 6 month outcome in schizophrenia?
