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.

Input: Consider Input: Anemia of chronic disease, a cytokine-mediated anemia, is a frequent complication of many chronic inflammatory conditions. The present case-control study was aimed to evaluate levels of systemic hematological markers indicative of anemia in patients with generalized, severe, chronic periodontitis.', 'A convenience quota sample of 30 systemically-healthy, urban, male patients comprised two groups, based on full mouth periodontal examination: group A patients (n=15) were diagnosed with generalized, severe, chronic periodontitis, and group B patients comprised the control group (n=15), which included patients with a clinically-healthy periodontium. Laboratory blood investigations included hemoglobin (g%), total number of erythrocytes (red blood cells), hematocrit/packed cell volume, erythrocyte sedimentation rate, mean corpuscular volume of erythrocytes, and mean corpuscular hemoglobin concentration. An analysis of covariance using age as a covariate was done to compare the mean values of hematological parameters within groups.', 'The mean values of hemoglobin, red blood cells, packed cell volume, and mean corpuscular hemoglobin concentration were significantly lower, while the mean corpuscular volume of erythrocytes and erythrocyte sedimentation rate were significantly higher in group A patients compared to those in group B, indicating mild anemia.

Input: Consider Input: This study used dopamine D2 receptor (D2R) knockout (KO) mice to investigate the role of D2R activity in the development of form-deprivation myopia (FDM). Sulpiride, a D2R antagonist, was administered systemically into wild-type (WT) mice to validate the involvement of D2R in FDM development.', 'The D2R KO and WT C57BL/6 mice were subjected to FDM. Wild-type mice received daily intraperitoneal injections of sulpiride, 8 μg/g body weight, for a period of 4 weeks. The body weight, refraction, corneal radius of curvature, and ocular axial components were measured at week 4 of the experiment. Differences in all ocular parameters between the experimental and control groups were compared statistically.', 'Form-deprivation myopia in D2R KO mice (FD-KO) was significantly reduced compared with their WT littermates (interocular difference, -2.12 ± 0.91 diopter [D] in FD-KO versus -5.35 ± 0.83 D in FD-WT, P = 0.014), with a smaller vitreous chamber depth (0.008 ± 0.006 vs. 0.026 ± 0.006 mm, P = 0.044) and axial length (-0.001 ± 0.007 vs. 0.027 ± 0.008 mm, P = 0.007). Furthermore, FDM was attenuated in animals treated with sulpiride (-2.01 ± 0.31 D in FD-sulpiride versus -4.06 ± 0.30 D in FD-DMSO, P < 0.001) compared with those treated with vehicle, with a retardation in growth of vitreous chamber depth (-0.001 ± 0.006 vs. 0.022 ± 0.004 mm, P = 0.003) and axial length (-0.004 ± 0.007 vs. 0.027 ± 0.005 mm, P = 0.001).

Input: Consider Input: Serum prostate-specific antigen (PSA) level is a widely used serum marker for diagnosis and management of prostate cancer. Although not well-defined, liver appears to be the most likely site of PSA metabolism. However, general anaesthesia usually changes hepatic blood flow, therefore it may affect the metabolism of PSA. In this study we investigated the affect of general anaesthesia on the serum total PSA, free PSA and free to total PSA levels.', '30 male patients who were hospitalised in the internal medicine clinic (non-surgery group) and 30 male patients who would undergo operation under general anaesthesia (15 for cholecystectomy and 15 for inguinal hernia repair) enrolled into the study. PSA measurement was done on the day of the hospitalisation (which was also the day of operation for surgery group), on the 24th hour following the first measurement and on the 21st day. Anaesthesia was standardized for all patients.', 'There was no statistically significant difference in serum total PSA (p >0.05), free PSA levels (p >0.05) and free to total PSA ratio (p >0.05) between the surgery and non-surgery groups. There were statistically significant decreases in the 24th hour total PSA levels (13.8% in surgery group, p <0.05, and 13.1% in non-surgery group, p <0.05) and in the free PSA levels (4.0% in surgery group, p <0.05, and 8.2% in non-surgery group, p <0.05). There was no statistically significant difference in the free to total PSA ratios (p >0.05 and p >0.05, respectively).
