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.

Centrosome orientation toward the leading edge of migrating cells depends on dynein and microtubules (MTs), as well as a number of signaling factors at the leading edge. However, centrosomes are maintained at the cell center during orientation in fibroblasts, suggesting that factors working at sites other than the leading edge may also be involved.', 'In a search for factors that function with dynein in centrosome orientation, we found that the polarity protein Par3 associated with dynein and that knockdown of Par3 inhibited centrosome orientation by disrupting the position of the centrosome at the cell center; this disrupted centrosome positioning is the same phenotype as that observed with dynein inhibition. Par3 associated with dynein through its N-terminal dimerization and PDZ1 domains and interacted specifically with dynein light intermediate chain 2 (LIC2). siRNA knockdown of LIC2, but not LIC1, or overexpression of LIC2 or the N-terminal domain of Par3, also inhibited centrosome orientation by disrupting centrosome position. In wound-edge fibroblasts, Par3 specifically localized to cell-cell contacts where it overlapped with MT ends and dynein puncta in a LIC2-dependent fashion. Live imaging showed that MTs exhibited increased pausing at cell-cell contacts compared to the leading edge and that this elevated pausing was dependent on Par3 and LIC2.

It is often suggested that immigrants with long-term pain do not benefit from rehabilitation to the same extent as native Swedish patients. In this study, an 8-week rehabilitation programme was evaluated according to its adaptation for immigrants.', "To establish whether there is a difference between immigrants and native Swedes concerning: (i) return-to-work, the patients' own estimation and their actual ability; (ii) higher level of activity; (iii) reduction in pain and analgesic use.", 'A total of 67 patients with persistent non-malignant pain completed the rehabilitation programme. Thirty (45%) of the patients were immigrants.', 'A 1- and a 3-year follow-up were made to compare the outcome between the 2 groups.', "There was no significant difference in the return-to-work rate between immigrants and native Swedes. However, the patients' prediction of their ability to return to work was higher among the non-immigrants. The level of activity was lower and pain intensity and use of analgesics were higher among the immigrants than the non-immigrants.

Statins and cholesterol absorption inhibitors lower the concentration of C-reactive protein (CRP). The genetic polymorphism of apolipoprotein (apo) E is a strong endogenous determinant of sterol homeostasis. We therefore examined the relationship of CRP to the apoE polymorphism.', 'We studied 739 and 570 subjects with or without stable angiographic coronary artery disease (CAD), respectively. In carriers of apoE2, apoB was lower (P<0.001) than in apoE3/3 homozygotes; in individuals with apoE3/4 and apoE4/4, it was higher (P<0.001). Both in the presence and absence of CAD, CRP was higher in carriers of apoE2 (P=0.002) and apoE3/3 homozygotes (P=0.032) than in individuals with apoE3/4 or apoE4/4. Fibrinogen and white cell count were not related to the apoE genotype. CRP was associated with CAD. Compared to the lowest tertile, crude odds ratios were 1.87 (95% confidence interval (CI), 1.43-2.45, P<0.001) and 2.24 (95% CI, 1.71-2.94, P<0.001) in the second and third tertile. In carriers of apoE2, the use of tertiles defined in controls with apoE2 only diminished the odds ratios for CAD. In apoE3/4 heterozygotes or apoE4/4 homozygotes, the use of tertiles specific for this group only slightly increased the odds ratios.
