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).

[EX Q]: Abstract: A carotid-cavernous fistula recurred 16 years after a Hamby procedure. The recurrence was manifested by subarachnoid hemorrhage originating from dilated draining pial veins. The fistula was closed with a balloon catheter introduced through a patent remnant of the cervical carotid artery. Patients who have previously undergone Hamby trapping and embolization should be reassessed for an occult fistula that could predispose them to intracranial bleeding.
Which is the apt title for the abstract? option1: Balloon occlusion of a recurrent carotid-cavernous fistula previously treated by carotid ligations. option2: Results and implications of the Hypertension Detection and Follow-up Program.
[EX A]: Balloon occlusion of a recurrent carotid-cavernous fistula previously treated by carotid ligations.

[EX Q]: Abstract: The roller screw electric VAD is easier to manufacture and 25% lighter than the previously described drum cam model. This device requires 12 to 15 W to pump 6 to 8 l/min with minimal hemolysis. The motor drive has functioned for periods up to 93 days in vivo with no measurable wear. The compliance chamber volume varies by 100 cc during VAD function but does so while maintaining pressure variations below 15 mmHg. Compliance chamber volume loss of 2 to 5 cc/day is explained by gas transport through SPU. The subcutaneous sampling port provides ready access to the sealed system.
Which is the apt title for the abstract? option1: Roller screw electric motor ventricular assist device. option2: Malignant pyoderma: a manifestation of Wegener's granulomatosis? [letter]

[EX Q]: Abstract: We have determined the messenger RNA activity profiles of epididymal fat in euthyroid, hypothyroid, and hyperthyroid rats as well as in animals fed a high carbohydrate fat-free (lipogenic) diet. Radioautographs of two-dimensional gels of the in vitro translational products of RNA were quantitated by computer-assisted videodensitometry and analyzed by multivariate statistics. Of the 250 spots observed, each presumably representing the translational product of a separate messenger RNA, 21 were responsive to changes in hormonal state. Eighteen increased and two decreased at some stage in the transition from the hypothyroid to the hyperthyroid state. One spot changed in a biphasic manner. Eight products responded to the lipogenic diet, six increasing and two decreasing. Six of these eight spots responded in a similar fashion to thyroid hormone administration. As previously shown for liver, there appears to be a substantial overlap between the genomic response to carbohydrate and thyroid hormone administration. Whereas the carbohydrate-generated changes are largely included in the thyroid-hormone induced alterations, the majority of thyroid hormone responsive changes are not duplicated by the diet. Multivariate analysis showed a clear separation of each state from the others and revealed that it was necessary to monitor only nine spots to achieve an effective separation of the states analyzed.
Which is the apt title for the abstract? option1: Effect of thyroid hormones and high carbohydrate feeding on gene expression in rat epididymal adipose tissue. option2: Pulse oximetry for continuous oxygen monitoring in sick newborn infants.
[EX A]:
