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.

Example Input: Chronic elevations in circulating C-reactive protein (CRP) are associated with a greater risk of hypertension. Whether elevations in CRP cause hypertension is unknown.', 'Chronic, conscious blood pressure (BP) measurements were performed by radiotelemetry in wild-type CF1 control and CF1 transgenic mice expressing rabbit CRP (CF1-CRP) under the regulation of the phosphoenolpyruvate carboxykinase promoter. Compared with controls, CF1-CRP mice had hypertension that was predominantly systolic, and the severity of hypertension varied in parallel with changes in CRP levels modulated by dietary manipulation. Mice that were hemizygous for the transgene with CRP levels of 9 microg/mL were also hypertensive, indicating that modest elevations in CRP are sufficient to alter BP. CRP transgenic mice had exaggerated BP elevation in response to angiotensin II and a reduction in vascular angiotensin receptor subtype 2 (AT2) expression. In contrast, the decline in BP with angiotensin receptor subtype 1 (AT1) antagonism and vascular AT1 abundance were unaltered, which indicates a selective effect of CRP on AT2. Ex vivo experiments further showed that the CRP-induced decrease in AT2 is a direct effect on the vascular wall, not requiring systemic responses, and that it is reversed by an NO donor, which indicates a role for NO deficiency in the process. In parallel, the chronic inhibition of NO synthase in wild-type mice attenuated vascular AT2 expression without affecting AT1.

Example Input: the use of antihypertensive medication in older people in order to prevent cardiovascular events is well established. The use of such agents has been encouraged by incentive schemes in the United Kingdom including the Quality and Outcomes Framework. In addition, many guidelines recommend good blood pressure (BP) control in the elderly. However, in older people antihypertensives can cause adverse effects related to hypotension.', 'the aim of this study was to assess the prevalence of low\xa0BP and impact on outcomes, particularly in the presence of antihypertensive treatment, in a primary care population of older people.', 'a retrospective observational cohort study in people over the age of 70 years registered with primary care providers in Kent.', 'a total of 11,167 patients over 70 years old were analysed, 6,373 female (57%). Systolic blood pressure (SBP) was below 120 mmHg in 1,297 people (844 on antihypertensives), below 110 mmHg in 474 (313 on antihypertensives) and below 100 mmHg in 128 (89 on antihypertensives). Hypotension was independently associated with mortality, acute kidney injury and hospital admission.

Example Input: The FAS/FASLG system has been proposed to play a key role in germ cell apoptosis. To elucidate the role of the genetic variants of cell death pathway genes in male infertility, we genotyped the polymorphisms of FAS, FASLG and caspase-8 (CASP8) genes and evaluated their effects on sperm apoptosis and semen quality in infertile men.', 'The genotypes of FAS, FASLG and CASP8 were determined in 620 infertile men. Sperm apoptosis rates were measured by terminal deoxynucleotidyl transferase (Tdt)-mediated dUTP nick end labelling (TUNEL) assay, and the semen quality analysis was performed using computer assisted sperm analysis.', 'We found that polymorphisms of FAS-670A/G (rs1800682: A>G) and CASP8-652 6N ins/del (rs3834129: -/CTTACT) were associated with sperm apoptosis and semen quality. Individuals with FAS-670GG showed low apoptosis rate and decreased sperm concentration, compared with the FAS-670AA genotype. Similarly, in comparison with the CASP8-652 6N ins/ins genotype, the CASP8-652 6N (ins/del+del/del) genotypes also showed significantly decreased sperm apoptosis rate and poor sperm motility. Other polymorphisms investigated did not appear to affect sperm apoptosis and semen quality.
