Detailed Instructions: Given an abstract, indicate which of the provided candidate titles (Option1 and Option2) best describes it (respond with the text of the title, not option1/2).
See one example below:
Problem: Abstract: Some patients converted from ventricular fibrillation to organized rhythms by defibrillation-trained ambulance technicians (EMT-Ds) will refibrillate before hospital arrival. The authors analyzed 271 cases of ventricular fibrillation managed by EMT-Ds working without paramedic back-up. Of 111 patients initially converted to organized rhythms, 19 (17%) refibrillated, 11 (58%) of whom were reconverted to perfusing rhythms, including nine of 11 (82%) who had spontaneous pulses prior to refibrillation. Among patients initially converted to organized rhythms, hospital admission rates were lower for patients who refibrillated than for patients who did not(53% versus 76%, P = NS), although discharge rates were virtually identical (37% and 35%, respectively). Scene-to-hospital transport times were not predictively associated with either the frequency of refibrillation or patient outcome. Defibrillation-trained EMTs can effectively manage refibrillation with additional shocks and are not at a significant disadvantage when paramedic back-up is not available.
Which is the apt title for the abstract? option1: Refibrillation managed by EMT-Ds option2: Maintenance of compliance in a small diameter arterial prosthesis.
Solution: Refibrillation managed by EMT-Ds
Explanation: The abstract is about refibrillation and it is also mentioned in the abstract that it is managed by EMT-Ds. So it is an apt title.

Problem: Abstract: Norepinephrine concentrations and tyrosine hydroxylase activity were determined in the brains of moderate-seizure and severe-seizure genetically epilepsy-prone rats (GEPRs) and in nonepileptic control rats. Both moderate-seizure (GEPR-3) and severe-seizure (GEPR-9) animals had widespread abnormalities in brain norepinephrine concentrations. Abnormalities in tyrosine hydroxylase activity were restricted to the midbrain. The state of abnormal seizure susceptibility, but not severity, in the GEPR may be determined by noradrenergic deficits in the hypothalamus/thalamus. Both seizure severity and susceptibility may be determined by noradrenergic deficits in the telencephalon, midbrain, and pons-medulla. Seizure severity but not susceptibility may be determined by noradrenergic abnormalities in the cerebellum.
Which is the apt title for the abstract? option1: Indices of noradrenergic function in the central nervous system of seizure-naive genetically epilepsy-prone rats. option2: Psychogenic upper airway obstruction presenting as refractory wheezing.
Solution:
Indices of noradrenergic function in the central nervous system of seizure-naive genetically epilepsy-prone rats.
