Teacher: In this task, you are given a abstract of article and corresponding title of an article. Your task is to generate label "yes" if title is right for article, otherwise generate "no".
Teacher: Now, understand the problem? If you are still confused, see the following example:
Abstract: This study was designed to determine the influence of a long-term, moderate-intensity treadmill training program on the distribution of blood flow within and among muscles of rats during exercise. One group (T) of male Sprague-Dawley rats trained for 1 h/day for 13-17 wk at 30 m/min on a motor-driven treadmill. A second group (UT) of rats was conditioned for 10 min/day for 4 wk at the same speed. Muscle succinate dehydrogenase activities were higher in T than UT rats indicating a significant training effect. Blood flows (BFs) in 32 hindlimb muscles or muscle parts and other selected organs were measured in the two groups with radiolabeled microspheres during preexercise and while the rats ran for 30 s, 5 min, or 15 min at 30 m/min on the treadmill. The data indicate 1) there were no differences in total hindlimb muscle BF between UT and T rats at any time; however, 2) T rats had higher preexercise heart rates and higher muscle BFs in the deep red extensor muscles, suggesting a greater anticipatory response to the impending exercise; 3) T rats demonstrated more rapid elevations in BF in the red extensor muscles at the commencement of exercise; 4) T rats had higher BFs in red extensor muscles during exercise, whereas UT rats had higher BFs in white muscles; and 5) T rats maintained higher BFs in the visceral organs during exercise. These findings demonstrate that exercise training results in changes in the distribution of BF within and among muscles and among organs during exercise. Specifically, data indicate the high-oxidative motor units that are primarily recruited in the muscles during the initial stages of moderate treadmill exercise receive higher blood flows in the trained rats; this presumably contributes to increased resistance to fatigue..

Solution: yes
Reason: Title is appropriate for the given abstract because the focus of this abstract is cerebral white matter assesment.

Now, solve this instance: Abstract: OBJECTIVE We investigated the outcome of repeated gamma knife radiosurgery (GKS) for local or remote recurrence after initial radiosurgery. MATERIAL AND METHODS We retrospectively reviewed 204 patients who were treated with GKS. Among them 43 patients (21%) underwent GKS more than once. The second GKS was given for recurrence at the previously treated sites in 16 patients, new lesions at remote sites in 13, and both local recurrence and new lesions in 14.
RESULTS The median survival from the first GKS was 36 (7-190) weeks in all patients and 68 (16-156) weeks in 43 patients with repeated GKS. The median time from the first GKS to the second was 37 weeks. The median survival from the second radiosurgical intervention was 32 (7-132) weeks. Local control rate at 6 months after salvage GKS was 90.7%. RPA class was the commonly dominant prognostic factor in both initial and salvage GKS.
CONCLUSION Recurrence is common for patients with metastatic brain tumors after initial radiosurgery. Local control and survival time after salvage treatment are comparable with those after initial radiosurgery. GKS as a salvage treatment may provide additional survival benefit in selected patients..
