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).
One example is below.
Q: 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.
A: Refibrillation managed by EMT-Ds
Rationale: 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.
Q: Abstract: The in vivo stimulation of vitamin D-dependent calcium-binding protein (9 K CaBP) synthesis by 1,25-dihydroxycholecalciferol [1,25(OH)2D3] in the rat duodenum has been analyzed using a specific [32P]complementary DNA probe for rat 9 K CaBP and inhibitors of RNA transcription (actinomycin D, alpha-amanitin) or protein synthesis (cycloheximide). The relative amounts of 9 K CaBP messenger RNA (mRNA) were assayed by dot-blot hybridization and the relative amounts of 9 K CaBP by RIA. Both inhibitors were injected at doses which significantly inhibited by 80-95% [35S]methionine or [3H]uridine incorporation into protein and RNA, respectively. In vitamin D-deficient rats, a single 1,25(OH)2D3 injection (650 pmol/100 g BW) resulted in a rapid production of 9 K CaBP mRNA which was significantly detectable as early as 3 h, and was followed by an increase of 9 K CaBP levels. Injection of actinomycin D (25 micrograms/100 g BW) 1 h before 1,25(OH)2D3 treatment and repeated every 4 h did not prevent the hormone-induced elevation of duodenal CaBP mRNA, even when the actinomycin dose was doubled and given 2 h before hormonal treatment. alpha-Amanitin (2 micrograms/100 g BW) also failed to block the hormonal stimulation. The protein synthesis inhibitor cycloheximide (25 micrograms/100 g BW) did not cause any change in the 1,25(OH)2D3-induced CaBP mRNA but blocked the CaBP increase after hormone injection. Thus, transcription inhibitors did not prevent the in vivo hormone-induced elevation of 9 K CaBP mRNA, which suggests that 1,25(OH)2D3 increases 9 K CaBP synthesis by increasing 9 K CaBP gene expression at one or more posttranscriptional steps. More precise data will be obtained by measuring the rate of 9 K CaBP gene transcription on isolated nuclei from rat duodenum.
