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.

[Q]: Cullin1 is a scaffold protein of the ubiquitin E3 ligase Skp1/Cullin1/Rbx1/F-box protein complex which ubiquitinates a broad range of proteins participating in biochemical events like cell-cycle progression, signal transduction, and transcription. Cullin1 is involved in the progression of several cancers, such as melanoma, breast cancer, and gastric cancer.', "To investigate the role of Cullin1 in the development of non-small-cell lung cancer (NSCLC), we examined the expression of Cullin1 in 8-paired fresh NSCLC tissues. We then constructed immunohistochemistry (IHC) on 114 paraffin-embedded slices and evaluated the correlation between Cullin1 expression and clinicopathologic variables, as well as patients' overall survival.", "We found that Cullin1 was highly expressed in NSCLC tissues and significantly associated with NSCLC's histological differentiation (P=0.002), clinical stage (P=0.010) and Ki-67 (P=0.021). Furthermore, we showed a strong correlation between high Cullin1 expression and worse overall survival rates in NSCLC patients (P<0.001). Cox regression analysis revealed that Cullin1 expression was an independent prognostic factor to predict 5-year patient outcome in NSCLC cancer (P=0.033).

[Q]: Thyroid cancer is the most common endocrine gland malignancy. Advances in understanding the genetic basis for thyroid cancer revealed the potential involvement of several genes in the formation of thyroid tumors. Mutations in the gene coding for succinate dehydrogenase subtype B (SDHB) have been implicated in papillary thyroid cancer (PTC). Succinate dehydrogenase (SDH) is a heterotetrameric protein composed of four subunits, SDHA, SDHB, SDHC, and SDHD, and participates in both the electron transport chain and the tricarboxylic acid cycle. The aim of the study was to evaluate the association between variants in the SDHA, SDHB, SDHC, and SDHD genes and familiar PTC in a large Brazilian family.', 'Four patients with PTC, 1 patient with PTC and gastrointestinal stromal tumor (GIST), 1 patient with GIST, and their relatives - several of them with different thyroid problems - from a large Brazilian family were screened for genetic variations of SDHx genes with the use of polymerase chain reaction-single-stranded conformational polymorphism and direct sequencing.', 'Only one rare variation in SDHA was found in some of the family members, but not segregating with the disease. No other genetic variants of these genes were detected in the family members that presented with PTC and/or GIST.

[Q]: Recent studies have reported the association of gamma-glutamyltransferase (GGT) or ferritin with metabolic disorders. However, there has been no large population-based study assessing the interrelationship of these two biomarkers and their association with insulin resistance.', "A population-based cross-sectional study was carried out in the Chinese Liangshan Yi ethnic group. 756 eligible subjects, aged 20 - 74 years, were included. Demographic characteristics, medical history, and lifestyle data were collected through questionnaires. An oral glucose tolerance test was performed. Laboratory tests, including GGT and ferritin measurements, were conducted. Spearman's rank-order correlation and multiple linear regression were used to calculate the correlation of GGT with ferritin and their relationship to the insulin resistance index determined by the homeostasis model assessment (HOMA-IR).", 'A significant correlation between serum GGT and ferritin levels was found (r = 0.393, p < 0.05). GGT was independently correlated with ferritin after adjustment for age, gender, place of residence, education, income, leisure-time physical activity, drinking, smoking, body mass index, systolic pressure, diastolic pressure, hepatitis B surface antigen, anti-hepatitis C virus, aspartate aminotransferase, alanine aminotransferase, total cholesterol, low density lipoprotein-cholesterol, triglyceride, high density lipoprotein-cholesterol, fasting plasma glucose, 2-hour postprandial plasma glucose, uric acid, and urinary albumin to creatinine ratio (p < 0.05). Positive correlations were established between HOMA-IR and GGT (standard β = 0.252) or ferritin (standard β = 0.181) after adjustment for multiple confounders (p < 0.05).
