Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

We aimed to investigate structural abnormalities in first-episode remitted geriatric depression (RGD) with optimized voxel-based morphometry (VBM) in closely matched patients and healthy control subjects and examine the relationship of performances on neuropsychological tests with regional gray matter volumes.', 'Nineteen subjects with first-episode RGD and 16 well-matched healthy control subjects were recruited for this study, and neuropsychological tests and magnetic resonance imaging were conducted on the subjects. The differences in regional gray matter volume were determined between these two groups by optimized VBM.', 'The volumes of right superior frontal cortex, left postcentral cortex, and right middle temporal gyrus were significantly smaller in patients with RGD relative to healthy control subjects. However, patients with RGD had larger left cingulate gyrus volume compared with healthy control subjects. There was a significant negative correlation between left cingulate gyrus volume and Rey Auditory Verbal Learning Test delayed recall raw score in patients with RGD.

Depressed mood has been prospectively associated with hypertension. Altered ANS function, as reflected in poor CV recovery, may be one mechanism that underlies this relationship.', 'The purpose of this study was to investigate the relationship between depressed mood and cardiovascular recovery following a standard mental stress task in healthy young women.', 'Depressed mood was assessed in 63 young women. Cardiovascular data were collected during a 5-min baseline period, 5-min public speaking stress task, and 15-min recovery period.', 'Depressed mood accounted for 9.6% of the variation in HR reactivity (F(1,58) = 6.513, p = 0.013) and 4.5% of DBP recovery (F(1,58) = 4.538, p = 0.037).

Our previous study demonstrated that prolonged cold preservation promoted neointima formation and remodeling but delayed the subsequent arteriosclerosis of rat abdominal aorta grafts. The mechanisms of this phenomenon remain obscure. In this study, we investigated whether stromal cell derived factor-1 (SDF-1) could play a role in recruiting stem cells to repair and remodel the damaged intima of abdominal aorta grafts.', 'Male Spague-Dawley rats received abdominal aorta grafts from male Wistar rats. Hematoxylin and eosin staining was performed to assess the structure of graft aortas by measuring the neointimal thickness. Immunohistochemical staining detected SDF-1 expression. RT-PCR demonstrated the expression of CXCR4, the only known natural receptor of SDF-1 expression on stem cells.', 'The neointimal thickness of the SDF-1 antibody-treated group was inconspicuous; a significant relationship existed between the expression of SDF-1 and the neointimal thickness of the grafts. Furthermore, no CXCR4 was detected in normal abdominal aortas, but it was observed in the grafted abdominal aorta.
