In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

[EX Q]: Context: Living a purposeful life is associated with better mental and physical health, including longevity. Accumulating evidence shows that these associations might be explained by the association between life purpose and regulation of physiological systems involved in the stress response. The aim of this study was to investigate the prospective associations between life purpose and allostatic load over a 10-year period.', 'Analyses were conducted using data from the Midlife in the United States (MIDUS) survey. Assessment of life purpose, psychological covariates and demographics were obtained at baseline, while biomarkers of allostatic load were assessed at the 10-year follow-up.', 'We found that greater life purpose predicted lower levels of allostatic load at follow-up, even when controlling for other aspects of psychological well-being potentially associated with allostatic load. Further, life purpose was also a strong predictor of individual differences in self-health locus of control-i.e., beliefs about how much influence individuals can exert on their own health-which, in turn, partially mediated the association between purpose and allostatic load. Although life purpose was also negatively linked to other-health locus of control-i.e., the extent to which individuals believe their health is controlled by others/chance-this association did not mediate the impact of life purpose on allostatic load.\Question: Does purpose in life predict allostatic load ten years later?
[EX A]: The current study provides the first empirical evidence for the long-term physiological correlates of life purpose and supports the hypothesis that self-health locus of control acts as one proximal psychological mechanism through which life purpose may be linked to positive biological outcomes.

[EX Q]: Context: Activation of NF-kappaB signaling pathway plays a critical role in the initiation and progression of carcinogenesis. However, the role of NF-kappaB pathway in esophageal squamous cell carcinoma (ESCC) has not been fully elucidated. Studies have shown that curcumin possesses anti-infection and anti-oxidation effects. This study was to evaluate whether curcumin could induce apoptosis through inhibition of NF-kappaB signaling pathway in ESCC cells.', 'Expressions of pIkappaBalpha and Bcl-2 were detected using Western blott after incubation of ESCC cells with curcumin (50 micromol/L) at different time points. Apoptosis and the number of viable ESCC cells were analyzed using flow cytometry and MTT, respectively, after the treatment of curcumin, 5-FU, or the combination of curcumin and 5-FU.', 'In two ESCC cell lines, EC9706 and Eca109,curcumin inhibited IkappaBalpha phosphorylation and Bcl-2 in a time-dependent manner; curcumin alone increased cell apoptosis (P<0.05), and the effect became more prominent when it was combined with 5-FU (P<0.05); curcumin plus 5-FU exerted a stronger inhibition effect on cell proliferation than curcumin alone (P<0.05) or 5-FU alone (P<0.05).\Question: Does [ Curcumin promote apoptosis of esophageal squamous carcinoma cell lines through inhibition of NF-kappaB signaling pathway ]?
[EX A]: Curcumin inhibits the phosphorylation of IkappaBalpha, leading to suppression of proliferation, induction of apoptosis and an increase of the sensitivity of ESCC cell lines towards 5-FU.

[EX Q]: Context: The efficacy of programmes to reduce long-term benzodiazepine use could be compromised by subsequent increases in contacts with the family practice. In this study the hypothesis was tested as to whether participation in a benzodiazepine discontinuation programme affects the frequency of contacts with the family practice.', 'A controlled stepped-care intervention programme to decrease long-term benzodiazepine use.', 'Family practices in the Netherlands. Subjects. The experimental group consisted of 996 long-term benzodiazepine users and a control group of 883 long-term benzodiazepine users.', 'Practice contacts before and up to 12 months after the start of the programme.', 'There was a general tendency visible for contacts to decrease during the follow-up time. The course of the number of contacts during the follow-up was not different for the experimental and control groups (p=0.45). The level of non-benzodiazepine prescriptions was generally not altered. The number of non-benzodiazepine prescriptions decreased in benzodiazepine quitters during the follow-up of the programme.\Question: Does a benzodiazepine discontinuation programme increase the frequency of contacts with the family practice?
[EX A]:
No clinically important differences in practice contacts were observed when the course of the number of contacts and non-benzodiazepine prescriptions were compared between the experimental and control groups. Family practitioners do not have to anticipate an increased workload associated with participation in such a benzodiazepine discontinuation programme.
