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.

To analyze whether peroxisome proliferator-activated receptor gamma (PPAR2) rs1801282 (Pro12Ala) polymorphism is associated with the response to pegylated-interferon-alpha plus ribavirin treatment in HIV/hepatitis C virus (HCV)-coinfected patients, and whether it is able to predict the outcome of HCV treatment.', 'Retrospective follow-up study.', 'Two hundred eighty-five naive patients, who started HCV-treatment, were genotyped for PPAR2 and interleukin 28B polymorphisms. Genetic data were analyzed under dominant inheritance model. Sustained virological response (SVR) was defined as undetectable HCV viremia through 24 weeks after the end of HCV treatment.', 'The variables significantly associated with SVR in a multivariate analysis were HCV-genotype (GT) 3 {adjusted odds ratio [aOR] = 7.66 [95% of confidence interval (95% CI): 3.96 to 14.81] P < 0.001}, HCV-viremia <500,000 IU/mL [aOR = 2.20 (95% CI: 1.16 to 4.15] P = 0.015), no/mild liver fibrosis (F < 2) [aOR = 1.92 (95% CI: 1.08 to 3.42) P = 0.026], IL28B rs12980275 AA genotype [aOR = 2.70 (95% CI: 1.54 to 4.71) P < 0.001], and PPAR2 rs1801282 CG/GG genotype [aOR = 2.93 (95% CI: 1.27 to 6.72) P = 0.011]. When PPAR2 rs1801282 genotype was included in a decision tree analysis, HCV-GT3 patients with CG/GG genotype had increased SVR from 80.3% to 100%. In GT1/4 patients, rs12980275 AA carriers had increased SVR from 58.7% to 78.6%, and rs12980275 AG/GG carriers had increased SVR from 28.7% to 35.7%. The overall percentage of patients correctly classified was 71.6% and the area under the receiver operating characteristic curves was 0.766 0.028.

B-type natriuretic peptide (BNP)-natriuretic peptide receptor A (NPR-A) receptor signalling inhibits cardiac sympathetic neurotransmission, although C-type natriuretic peptide (CNP) is the predominant neuropeptide of the nervous system with expression in the heart and vasculature. We hypothesized that CNP acts similarly to BNP, and that transgenic rats (TGRs) with neuron-specific overexpression of a dominant negative NPR-B receptor would develop heightened sympathetic drive.', 'Mean arterial pressure and heart rate (HR) were significantly (P<0.05) elevated in freely moving TGRs (n=9) compared with Sprague Dawley (SD) controls (n=10). TGR had impaired left ventricular systolic function and spectral analysis of HR variability suggested a shift towards sympathoexcitation. Immunohistochemistry demonstrated co-staining of NPR-B with tyrosine hydroxylase in stellate ganglia neurons. In SD rats, CNP (250nM, n=8) significantly reduced the tachycardia during right stellate ganglion stimulation (1-7Hz) in vitro whereas the response to bath-applied norepinephrine (NE, 1M, n=6) remained intact. CNP (250nM, n=8) significantly reduced the release of

To investigate the relation between restless legs syndrome (RLS) and obstructive sleep apnea symptoms during pregnancy.', 'A questionnaire consisting of diagnostic criteria of restless legs syndrome, demographic characteristics, personal behavior, muscle cramps during pregnancy, past medical illnesses, family history of RLS, and the major symptoms of obstructive sleep apnea syndrome was administered during a face-to-face interview. Pregnant women with and without RLS were compared in terms of serum hemoglobin, hematocrit, calcium, phosphor, iron, folate, vitamin B12 levels, and obstructive sleep apnea symptoms.', 'There were statistically significant differences between two groups in terms of two of the obstructive sleep apnea symptoms (witnessed apnea and fatigue) (p<0.01). No statistically significant difference was found with regard to serum calcium, magnesium, iron, hemoglobin, hematocrit, vitamin B12, phosphor, and folate levels; however, there were significant differences in terms of total iron-binding capacity.
