Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

We recently proposed the existence of neurotoxic interactions between the cannabinoid type 1 (CB(1)) receptor and transient receptor potential vanilloid 1 (TRPV1) channels in rat mesencephalic cultures. This study seeks evidence for the mediator(s) and mechanisms underlying the neurotoxic interactions between CB(1) receptors and TRPV1 in vitro and in vivo.', 'The mediator(s) and mechanism(s) for the interactions between CB(1) receptors and TRPV1 were evaluated by cell viability assays, immunocytochemistry, Fura-2 calcium imaging, mitochondrial morphology assay, ELISA and Western blot assay in vitro in neuron-enriched mesencephalic cultures. Injections into the substantia nigra and subsequent cell counts were also used to confirm these interactions in vivo.', 'The neurotoxic interactions were mediated by 12(S)-hydroperoxyeicosatetraenoic acid (12(S)-HPETE), an endogenous TRPV1 agonist. CB(1) receptor agonists (HU210 and WIN55,212-2) increased the level of 12(S)-hydroxyeicosatetraenoic acid (12(S)-HETE), a downstream metabolite of 12(S)-HPETE, which stimulates TRPV1-mediated death of mesencephalic neurons, both in vitro and in vivo. The neurotoxicity was mediated by increased intracellular Ca(2+) concentration ([Ca(2+)](i)) through TRPV1, consequently leading to mitochondrial damage and was attenuated by baicalein, a 12-lipoxygenase inhibitor.

Ex Output:
Are interactions between CB ( 1 ) receptors and TRPV1 channels mediated by 12-HPETE cytotoxic to mesencephalic dopaminergic neurons?

High sensitivity C-reactive protein (Hs-CRP) and adiponectin (APN) are two critical cytokines and exert inverse effects on atherosclerosis initiation and progression. The purpose of our study was to investigate the value of Hs-CRP and ANP ratio (Hs-CRP/APN ratio) on evaluating atherosclerosis progression.', "One hundred sixty consecutive participants underwent carotid intima-media thickness (CIMT) measured by ultrasound were enrolled and drawn fasting blood samples for plasma levels Hs-CRP and APN, serum levels of lipid profiles and fasting blood glucose evaluation. Other anthropometrics and clinical status were collected by questionnaire. All participants were divided into 4 groups according to the baseline Hs-CRP/APN ratio and underwent CIMT measurement every 6 months. CIMT increment and composite cardiovascular endpoints were compared after 24 months' follow-up.", "At baseline, body mass index (BMI), smoking, diabetic mellitus, usage of statins, Hs-CRP and APN independently correlated with Hs-CRP/APN ratio as analyzed by spearman rank correlation. Smoking, serum level of LDL-C, plasma level of Hs-CRP and Hs-CRP/APN ratio were positively correlated with CIMT while usage of statins and plasma level of APN were negatively correlated with CIMT as analyzed by multiple linear regression analysis. After 24 months' follow-up, the progression of CIMT was the most prominent in the fourth quartile of baseline Hs-CRP/APN ratio. In addition, the incidence of composite cardiovascular endpoint was also higher in the fourth quartile as compared to the other 3 lower quartiles.

Ex Output:
Is increased Hs-CRP/adiponectin ratio associated with increase carotid intima-media thickness?

To evaluate if return of spontaneous ventilation to pre-relaxation values indicates complete recovery from neuromuscular blockade.', 'Prospective, with each individual acting as its own control.', 'Ten healthy adult female Beagle dogs weighing 6.2-9.4\xa0kg.', 'Dogs were anesthetized with propofol, dexemedetomidine and isoflurane. Spontaneous ventilation was assessed by measuring end-tidal CO2 , expired tidal volume, peak inspiratory flow, respiratory rate and minute ventilation. Vecuronium 25\xa0μg\xa0kg(-1) IV was administered and neuromuscular block was evaluated by measuring the train-of-four (TOF) ratio with acceleromyography in the hind limb. During spontaneous recovery from neuromuscular block, the TOF ratio when each ventilatory variable returned to baseline was recorded.', 'This dose of vecuronium produced moderate neuromuscular block in all dogs, with TOF ratio values of 0-18% at maximal block. Expired tidal volume, peak inspiratory flow and minute ventilation returned to pre-relaxation values when the median TOF ratio was ≤ 20%. The median TOF ratio was 42% when the end-tidal CO2 returned to pre-relaxation values.

Ex Output:

Does recovery from neuromuscular block in dogs : restoration of spontaneous ventilation exclude residual blockade?
