Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Input: Consider Input: Context: To investigate the differential expressions of nucleolin in invasive cervical squamous cell carcinoma, cervical intraepithelial neoplasms (CIN) and normal cervical epithelial tissues and explore the role of nucleolin in the carcinogenesis and progression of cervical squamous cell carcinoma.', 'Fifty specimens of invasive cervical squamous cell carcinoma, 65 specimens of CIN, and 60 adjacent normal cervical epithelial tissue specimens were examined immunohistochemically for nucleolin expression. The correlation of nucleolin expression levels with histological grades of invasive cervical squamous cell carcinoma and CIN were analyzed.', 'The specimens of invasive cervical squamous cell carcinoma showed a significantly higher positivity rate for nucleolin expression than CIN and normal cervical epithelial tissues, and the rate in CIN tissues was significantly higher than that in normal cervical epithelial tissues (P<0.01). The expression level of nucleolin was significantly higher in invasive cervical squamous cell carcinoma than in CIN and normal cervical epithelia tissues, and higher in CIN than in normal cervical epithelia tissues, whose immunostaining scores were 7.6±0.3, 6.1±0.2, and 3.0±0.2, respectively (P<0.01). The mean nucleolin immunostaining score was significantly higher in poorly and moderately differentiated than in highly differentiated cervical squamous cell carcinoma (7.9 vs 7.1, P<0.01), and higher in high grade CIN than in low grade CIN tissues (6.0 vs 4.0, P<0.01).
Answer: Overexpression of nucleolin plays an important role during carcinogenesis of cervical squamous cell carcinoma and is positively correlated with tumor progression of CIN and cervical squamous cell carcinoma.

Output: Is [ Nucleolin expression correlated with carcinogenesis and progression of cervical squamous cell carcinoma ]?


Input: Consider Input: Context: Psychomotor abnormalities characterize both unipolar (UP) depression and bipolar (BP) depression. We aimed to assess their neurobiological correlates in terms of motor activity (AL) and resting-state cerebral blood flow (rCBF) and investigate their association in BP, UP, and healthy controls (HC).', 'We enrolled 42 depressed patients (22 BP, 20 UP) and 19 HC matched for age, gender, education, income. AL and rCBF were objectively assessed with the use of wrist actigraphy and arterial spin labeling. Group differences and the association of AL and rCBF were computed.', 'Activity level was significantly reduced in patients, but no difference was found between BP and UP. Increased perfusion was found in BP compared with UP and HC, in multiple brain areas. We found positive correlations of rCBF and AL in BP and UP, in different parts of the insula and frontal regions. Only BP showed a cluster in the left precentral gyrus. In HC, only inverse correlations of AL and rCBF were found.
Answer: The differences in rCBF and in the localization of the clusters of positive AL/rCBF correlations between BP and UP suggest that different neural impairments may underlie motor symptoms in the two disorders, but finally converge in phenotypically similar manifestations.

Output: Do distinct resting-state perfusion patterns underlie psychomotor retardation in unipolar vs. bipolar depression?


Input: Consider Input: Context: The cannabinoid receptor 1 gene (CNR1) is implicated in adipocyte function.', 'We investigated human adipose tissue CNR1 mRNA in relation to obesity, clinical and metabolic variables, adipocyte function, and adiponectin (ADIPOQ) levels.', 'We assessed sc fat biopsies from 96 obese and nonobese subjects and omental fat biopsies from 82 obese and nonobese subjects.', 'The sc and omental adipose CNR1 gene expression were similar in obese and nonobese subjects. No association between either sc or omental adipose CNR1 mRNA levels and body mass index, waist circumference, plasma levels of glucose and insulin, lipids, or blood pressure was found. The sc and omental maximal adrenergic lipolytic activation as well as lipolytic adrenoceptor sensitivity were not related to CNR1 gene expression. Lipogenesis in sc adipocytes also showed no association with CNR1 mRNA levels. Finally, no relation was found between adipose CNR1 gene expression and ADIPOQ mRNA, adipose tissue adiponectin secretion, or circulating adiponectin.
Answer: We found no association of human adipose tissue CNR1 mRNA expression with measures of body fat, metabolic parameters, fat cell function, or ADIPOQ expression. These data do not suggest a major role of human adipose CNR1 in fat cell function or metabolic disease development.


Output: Is human adipose tissue cannabinoid receptor 1 gene expression related to fat cell function or adiponectin level?
