Teacher: 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).
Teacher: Now, understand the problem? If you are still confused, see the following example:
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
Reason: 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.

Now, solve this instance: Abstract: DNA measurements yield information about the nature of cells and may provide diagnostic and prognostic information. Static cytofluorometry was performed on smears removed at microlaryngoscopy from 107 vocal cord lesions (96 patients). All stem cell lines were diploid except 3; 2 carcinomas and 1 severe dysplasia were polyploid. The mean proliferative activity (percentage of nuclei greater than diploid peak) was 2.1% for the group of epithelia with hyperplasia and mild dysplasia, 3.1% for those with moderate dysplasia, 4.0% for severe dysplasia, and 6.8% for carcinomas. Hypertetraploid cell nuclei (HT cells) were not found in epithelia with hyperplasia and mild dysplasia. Seven out of 15 patients with epithelia showing moderate dysplasia had HT cells; 5 of these patients developed a carcinoma. One of 8 without HT cells developed a severe dysplasia. Nine patients with severe dysplasia had HT cells; 4 had recurrences and 4 developed carcinoma within 4 years. In 14 patients without HT cells, 3 had recurrences and 1 developed a carcinoma 6 years later. HT cells were found in 15 patients with T1 & T2 carcinomas; residual carcinoma was present in 2 after radiotherapy and 4 had recurrences within 11 months. Fourteen patients with T1 & T2 carcinoma did not have any HT cells; one had residual carcinoma after radiotherapy and 3 had recurrences between 18 months and 4 years. DNA measurements and, especially, the demonstration of epithelia with HT cells prove to be of prognostic importance.(ABSTRACT TRUNCATED AT 250 WORDS)
