Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

[Q]: Bradykinin is a neuropeptide released after tissue damage which plays an important role in inflammatory pain. The up-regulation of the bradykinin B1 receptor in response to inflammation makes it an attractive target for drug development. Aim was to investigate if the selective B1 receptor antagonist BI113823 reduces inflammation-induced mechanical hyperalgesia and if the effect is mediated via peripheral and/or spinal B1 receptor antagonism.', "Electrophysiological recordings of peripheral afferents and spinal neurons were combined with behavioural experiments to better understand the underlying mechanisms of B1 receptor antagonism. Experiments were performed 24h after injection of complete Freund's adjuvant (CFA) or saline into the paw of Wistar rats. A gene expression analysis for the B1 receptor was performed in different tissues. BI113823 was administered orally or intrathecally to assess effects on CFA-induced hyperalgesia. Peripheral afferents of the saphenous nerve as well as spinal wide dynamic range (WDR) and nociceptive-specific (NS) neurons were recorded, and mechanosensitivity was measured before and after BI113823 administration.", 'BI113823 reduced CFA-induced mechanical hyperalgesia when administered orally or intrathecally. An increased B1 receptor gene expression was found in peripheral and spinal neural tissue. BI113823 significantly reduced mechanosensitivity of peripheral afferents and spinal NS neurons, but had no effect on WDR neurons.

[Q]: To investigate the surgical techniques and speech performance of multichannel auditory brainstem implant (ABI) in patients with bilateral acoustic neuromas (neurofibromatosis type 2).', 'The nucleus 21 channel auditory brainstem implant was implanted into the lateral recess of the fourth ventricle through the translabyrinthine approach in 7 patients after removal of the tumor. The accurate placement of electrode array was ensured by the electromyogram monitoring of the 7th and 9th nerves and the electrically evoked auditory brainstem responses (EABR). Initial switch-on occurred six weeks postoperatively. Speech evaluation was performed every 3 months for the first year and annually thereafter.', 'During the surgery, the lateral recess could be found and the typical EABR could be recorded in 6 cases. They later reported a significant benefit from the device. Two of the cases have achieved functional open-set speech understanding. In contrast, one patient with no EABR because of difficulty of the anatomic location during the surgery had no sensations postoperatively.

[Q]: Clonidine prolongs the duration of sensory and motor block induced by bupivacaine, and this association, in constant infusion by the epidural route, is used for postoperative analgesia. After a near-fatal intravenous bolus of bupivacaine in dogs, clonidine improves ventricular electrophysiologic parameters, but probably worsens bupivacaine-induced bradycardia and depression of the myocardial contractility. The current study, using a rodent animal model, evaluated the influence of clonidine pretreatment on the systemic toxic effects of bupivacaine overdose induced by a constant intravenous infusion.', 'Twenty Wistar male rats were anesthetized with thiopental, and controlled ventilation was started with an equal mixture of O2 and N2O. Electrocardiogram (ECG), electroencephalogram (EEG), and invasive arterial blood pressure were continuously recorded. Clonidine (5 micrograms/kg) or saline was injected intravenously in a randomized fashion. After 15 min, an intravenous infusion of bupivacaine was started at 2 mg.kg-1 x min-1. The time of occurrence of the bupivacaine-induced toxic events was recorded and the doses were calculated. Ten (five in each group) additional rats, pretreated according to the same protocol, were killed at the time of the first dysrhythmia, for blood sampling and plasma bupivacaine concentration measurement.', 'Clonidine reduced heart rate and arterial blood pressure before bupivacaine infusion (P < 0.05). The threshold doses at the first QRS modification (11.3 +/- 5.6 vs. 2.1 +/- 0.9 mg/kg) and the first dysrhythmia (40.6 +/- 15.3 vs. 8.48 +/- 3.7 mg/kg), the increase in EEG total spectral power (33.3 +/- 21.9 vs. 8.2 +/- 5.1 mg/kg), the 25 and 50% reduction in baseline mean arterial pressure and heart rate, the isoelectric EEG (58.6 +/- 14 vs. 22 +/- 6.6 mg/kg), and the final systole (99 +/- 16 vs. 51.8 +/- 14.5 mg/kg) were significantly greater in the clonidine group than in the saline group (P < 0.01). The time between the first dysrhythmia and 50% reduction of baseline mean arterial blood pressure was not different between the groups. In the additional series, the first dysrhythmia occurred later (10.9 +/- 4.5 vs. 3.2 +/- 1.0 min, P < 0.01) and plasma bupivacaine levels were greater (18.7 +/- 8.0 vs. 7.8 +/- 3.2 micrograms/ml, P < 0.01) in the clonidine group than in the saline group.
