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.
question:
Single nucleotide polymorphisms (SNPs) in approximately 40 genes have been associated with an increased risk for type 2 diabetes (T2D) in genome-wide association studies. It is not known whether a similar genetic impact on the risk of prediabetes (impaired glucose tolerance [IGT] or impaired fasting glycemia [IFG]) exists.', 'In our cohort of 1442 non-diabetic subjects of European origin (normal glucose tolerance [NGT] n\u200a=\u200a1046, isolated IFG n\u200a=\u200a142, isolated IGT n\u200a=\u200a140, IFG+IGT n\u200a=\u200a114), an impact on glucose homeostasis has been shown for 9 SNPs in previous studies in this specific cohort. We analyzed these SNPs (within or in the vicinity of the genes TCF7L2, KCNJ11, HHEX, SLC30A8, WFS1, KCNQ1, MTNR1B, FTO, PPARG) for association with prediabetes.', 'The genetic risk load was significantly associated with the risk for IGT (p\u200a=\u200a0.0006) in a model including gender, age, BMI and insulin sensitivity. To further evaluate potential confounding effects, we stratified the population on gender, BMI and insulin sensitivity. The association of the risk score with IGT was present in female participants (p\u200a=\u200a0.008), but not in male participants. The risk score was significantly associated with IGT (p\u200a=\u200a0.008) in subjects with a body mass index higher than 30 kg/m(2) but not in non-obese individuals. Furthermore, only in insulin resistant subjects a significant association between the genetic load and the risk for IGT (p\u200a=\u200a0.01) was found.

question:
Vein bypass is an essential therapy for patients with advanced peripheral and coronary artery disease despite development of neointimal hyperplasia. We have shown that stimulation of the receptor tyrosine kinase ephrin type-B receptor 4 (Eph-B4) with its ligand ephrin-B2 prevents neointimal hyperplasia in murine vein grafts. This study determines whether Eph-B4 in adult human veins is capable of phosphorylation and activation of downstream signaling pathways, as well as functional to release nitric oxide (NO) and prevent neointimal hyperplasia in vitro.', 'Discarded human saphenous veins were taken from the operating room and placed in organ culture without or with ephrin-B2/Fc (2 μg/mL) for 14 days, and the neointima/media ratio was measured in matched veins. Primary human umbilical vein endothelial cells were treated with ephrin-B2/Fc (2 μg/mL) and examined with quantitative polymerase chain reaction, Western blot, immunoassays, and for release of NO. Ephrin-B2/Fc (2 μg/mL) was placed on the adventitia of saphenous veins treated with arterial shear stress for 24 hours in a bioreactor and activated Eph-B4 examined with immunofluorescence.', 'The baseline intima/media ratio in saphenous vein rings was 0.456 ± 0.097, which increased to 0.726 ± 0.142 in untreated veins after 14 days in organ culture but only to 0.630 ± 0.132 in veins treated with ephrin-B2/Fc (n = 19, P = .017). Ephrin-B2/Fc stimulated Akt, endothelial NO synthase and caveolin-1 phosphorylation, and NO release (P = .007) from human umbilical vein endothelial cells (n = 6). Ephrin-B2/Fc delivered to the adventitia stimulated endothelial Eph-B4 phosphorylation after 24 hours of arterial stress in a bioreactor (n = 3).

question:
Clinically, early life stress and anxiety disorders are associated with increased vulnerability for alcohol use disorders. In male rats, early life stress, imparted by adolescent social isolation, results in long-lasting increases in a number of behavioral risk factors for alcoholism, including greater anxiety-like behaviors and ethanol (EtOH) intake. Several recent studies have begun to use this model to gain insight into the relationships among anxiety measures, stress, EtOH intake, and neurobiological correlates driving these behaviors. As prior research has noted significant sex differences in the impact of adolescent stress on anxiety measures and EtOH drinking, the current study was conducted to determine if this same model produces an "addiction vulnerable" phenotype in female rodents.', 'Female Long Evans rats were socially isolated (SI; 1/cage) or group housed (GH; 4/cage) for 6\xa0weeks during adolescence. After this housing manipulation, behavioral assessment was conducted using the elevated plus maze, response to novelty in an open field environment, and the light/dark box. After behavioral testing, home cage EtOH drinking was assessed across an 8-week period.', 'No group differences were detected in any of the behavioral measures of unconditioned anxiety-like behavior. Greater EtOH intake and preference were observed in SI females but these differences did not persist.
