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).

Example input: 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.
Example output: Refibrillation managed by EMT-Ds
Example 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.
Q: Abstract: Primary monolayer cultures of human fetal adrenal cells maintained in either lipoprotein-depleted or lipoprotein-supplemented media responded chronically to ACTH treatment with similarly increased steroid secretion. The principal steroid secreted into each medium was dehydroepiandrosterone sulfate. The presence of human low density lipoprotein (hLDL) in the medium enhanced the secretion of nonsulfoconjugated steroids, especially dehydroepiandrosterone. The secretion rate of 11 beta-hydroxyandrostenedione was similar to that of cortisol. In the absence of hLDL, ACTH increased cholesterologenesis to maintain the high rates of steroid secretion. After ACTH treatment, increased accumulation of 3-hydroxy-3-methylglutaryl coenzyme A reductase, a rate-determining enzyme of cholesterol biosynthesis, was found. Immunoblot analysis demonstrated that this enzyme was a 97K protein in human fetal adrenal cells. Interestingly, the content of this enzyme in cells treated with ACTH in lipoprotein-depleted medium was similar to that in adrenal fetal zone tissue. This finding suggests that cholesterologenesis de novo in addition to plasma LDL is important as a source of steroid precursor in vivo in the human fetal adrenal gland.
Which is the apt title for the abstract? option1: Steroidogenesis in the human fetal adrenal: a role for cholesterol synthesized de novo. option2: A quantitative comparison of satellite cell ultrastructure in Duchenne muscular dystrophy, polymyositis, and normal controls.
