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).

Q: Abstract: Pillars of calcification are rarely found in the skin. An interesting case is described where rows of new bone developed in the skin which had been grafted 31 years previously to cover partial skin thickness burns of the shin. The problems of heterotropic ossification are discussed.
Which is the apt title for the abstract? option1: Calcinosis cutis--a rare late complication of burns. option2: Plicatic acid-specific IgE and nonspecific bronchial hyperresponsiveness in western red-cedar workers.

A: Calcinosis cutis--a rare late complication of burns.

Q: Abstract: Men and women with dementia of the Alzheimer type (DAT) had more brain atrophy and ventricular dilatation, measured by quantitative CT, than did respective age- and sex-matched healthy controls (p less than 0.05). The male DAT patients with mild dementia had a larger mean third ventricle volume, whereas male patients with severe dementia had larger lateral and third ventricle volumes, more CSF, and less gray matter than did controls. Statistically significant and appropriate correlations between several dementia scales and CT measures in the DAT patients indicated that brain atrophy and ventricular dilatation were related to the severity of dementia.
Which is the apt title for the abstract? option1: Quantitative computed tomography in dementia of the Alzheimer type. option2: Histones and metal-binding domains.

Q: Abstract: Atrial pacing was performed in 16 patients with angina at rest and significant coronary artery stenosis (greater than 70%) over 2 consecutive days in the morning (10 A.M. to 1 P.M.), in the afternoon (4 to 7 P.M.), and at night (12 midnight to 3 A.M.) to assess possible circadian variations of their ischemic threshold. Overall, the incidence of resting angina was highest at night. All pacing results were positive (greater than or equal to 1.0 mm ST segment shift) and tended to be reproducible in nine patients, whereas some or all were negative in seven. Among all positive results, ischemic thresholds at night were significantly lower than those in the morning and in the afternoon (125 +/- 3 vs 138 +/- 3 and 139 +/- 2 beats/min, mean +/- SEM; p less than .005). In nine patients, 19 pacing tests produced ST segment elevation, of which 13 were performed at night (68%). We conclude that patients with resting angina and severe coronary stenosis often exhibit a nocturnal decline in their ischemic threshold, which seems to facilitate development of transmural ischemia during atrial pacing.
Which is the apt title for the abstract? option1: Resting angina with fixed coronary artery stenosis: nocturnal decline in ischemic threshold. option2: Is hypertrophic osteoarthropathy really so rare in regional enteritis?

A:
Resting angina with fixed coronary artery stenosis: nocturnal decline in ischemic threshold.
