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: Smoking, largely through increased oxidative stress, causes endothelial dysfunction which is an early key event in atherosclerosis. Smoking cessation and antioxidant vitamin therapy are shown to have beneficial role by restoring altered endothelial physiology. The present study was aimed to determine whether Terminalia arjuna, an Indian medicinal plant with potent antioxidant constituents, would improve endothelial dysfunction in smokers.', 'Eighteen healthy male smokers (age 28.16+/-9.45 years) and equal number of age-matched non-smoker controls participated in the study. The baseline brachial artery reactivity studies were performed using high frequency ultrasound according to standard protocol under identical conditions to determine endothelium-dependent, flow-mediated dilation and endothelium-independent nitroglycerine-mediated dilation. The two groups were matched regarding age, body mass index, blood pressure, serum cholesterol, mean resting vessel diameters and post-occlusion flow velocities (all p=NS). While flow-mediated dilation was significantly impaired amongst smokers compared to controls (4.71+/-2.22 v. 11.75+/-5.94%, p <0.005), the nitroglycerine-mediated dilation was similar in the two groups (20.35+/-3.89 v. 19.68+/-3.74%, p=NS). Subsequently the smokers were given Terminalia arjuna (500 mg q8h) or matching placebo randomly in a double blind cross-over design for two weeks each, followed by repetition of brachial artery reactivity studies to determine various parameters including flow-mediated dilation after each period. There was no significant difference as regards vessel diameter and flow velocities between the two therapies. However, the flow-mediated dilation showed significant improvement from baseline values after Terrminalia arjuna therapy but not with placebo (9.31+/-3.74 v. 5.17+/-2.42%, p <0.005).

Example Input: Hippocampal neurodegeneration is one of the hallmarks in neurological and neurodegenerative diseases such as temporal lobe epilepsy and Alzheimer disease. Human embryonic kidney (HEK) cells are a mixed population of cells, including neurons, and their conditioned medium is enriched with erythropoietin (EPO). Because EPO is a known neuroprotectant, we hypothesized that infusion of HEK cells or HEK-conditioned medium (HEK-CM) may provide neuroprotection against kainic acid (KA)-induced hippocampal damage in mice.', 'Adult CF1 mice were treated with KA to induce hippocampal damage. On 3rd and 5th days after KA treatment, HEK cells or HEK-CM was infused intravenously through the tail vein. On the 7th and 8th days after KA treatment, all groups of mice were subjected to cognitive and depression assessment by use of a novel object recognition test and a forced swim test, respectively. Subsequent to this assessment, mice were killed and the brain samples were used to assess the histopathology and messenger RNA expression for EPO and B-cell lymphoma-2 (Bcl-2).', 'We found that infusion of HEK cells/HEK-CM improves cognitive function and alleviates symptoms of depression. Histological assessment demonstrates complete neuroprotection against KA-mediated excitotoxicity, and the hippocampal cytoarchitecture of HEK cells/HEK-CM treated mice was comparable to normal control mice. HEK cells/HEK-CM treatment could provide neuroprotection by upregulating the endogenous EPO and Bcl-2 in KA-treated mice.

Example Input: Adipose tissue of obese subjects is known to exhibit increased inflammatory activity linked to altered expression of factors involved in glucose and lipid metabolism. The surgical procedure constitutes an injury per se, evoking a systemic inflammatory response.', 'To evaluate changes in the expression of key-genes in adipose tissue after common surgical procedures performed in obese patients.', 'A tertiary hospital.', 'Paired subcutaneous (SAT) and visceral (VAT) adipose tissue samples were collected at the beginning and the end of surgery in 33 obese patients that underwent laparoscopic Roux-en-Y gastric bypass (RYGB, n = 17) or laparoscopic vertical sleeve gastrectomy (SG, n = 16). The expression of genes involved in inflammation, glucose and lipid metabolism was assessed.', 'The surgical procedure led to increased expression of interleukin 6, interleukin 8 (P<.0001 in both depots), tumor necrosis factor α (P = .001 in SAT), and lipopolysaccharide binding protein (P = .0004 in VAT). Surgery also induced concomitant decreased expression of GLUT4, IRS1 (P = .046 in VAT), and adiponectin, whereas the messenger RNA of lipogenic genes [fatty acid synthase (P = .024); sterol regulatory element binding transcription factor 1 (P = .011) and aquaporin 9 (P<.0001) in SAT; and PPARγ (P = .018) and solute carrier family 27 (fatty acid transporter), member 2 (P = .028) in VAT] increased in parallel to inflammation. Changes in gene expression during surgery were enhanced in patients following RYGB, when compared with SG.
