instruction:
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:
Event-related potentials (ERPs) are sensitive measures of both perceptual and cognitive processes. The aim of the present study was to identify brain regions involved in the processes of cognitive dysfunction in narcolepsy by means of ERP tomography.', 'In 17 drug-free patients with narcolepsy and 17 controls, ERPs were recorded (auditory odd-ball paradigm). Latencies, amplitudes and LORETA sources were determined for standard (N1 and P2) and target (N2 and P300) ERP components. Psychometry included measures of mental performance, affect and critical flicker fusion frequency (CFF).', 'In the ERPs patients demonstrated delayed cognitive N2 and P300 components and reduced amplitudes in midline regions, while N1 and P2 components did not differ from controls. LORETA suggested reduced P300 sources bilaterally in the precuneus, the anterior and posterior cingulate gyri, the ventrolateral prefrontal cortex and the parahippocampal gyrus. In psychometry, patients demonstrated deteriorated mood, increased trait anxiety, decreased CFF and a trend toward reduced general verbal memory and psychomotor activity.

question:
Immunosuppressant agents modulate the activity of the immune system and control adipose tissue inflammatory responses associated with obesity. Controlling adipose tissue inflammation represents an interesting option for inhibiting the low-grade inflammatory state in obese subjects and for preventing obesity-associated pathologies. In this work, we assessed the effects of thalidomide on the inflammatory response in adipose tissue as well as on systemic inflammatory marker expression in the well-established high-fat diet-induced obesity mouse model.', 'Swiss male mice were fed a high-fat diet (60% kcal from fat) for 12 weeks and received thalidomide for the last 10 days (100 mg.kg-1). Adipokine levels were measured in serum and adipose tissue by EIA and real-time quantitative PCR, respectively. Adipose tissue infiltrating macrophages were identified by immunohistochemistry and western blot analysis of F4/80 marker expression. Other inflammatory markers, such as c-Jun N-terminal kinase (JNK) phosphorylation and monocyte chemoattractant protein-1 (MCP-1) production, were also evaluated by western blot analysis. In vitro assays using 3T3-L1 adipocytes were also conducted to evaluated adipokine release.', 'In obese mice, thalidomide administration induced a reduction in adiposity accompanied by a reduction of tumor necrosis factor- (TNF-), leptin and MCP-1 adipose tissue production, macrophage infiltration and JNK activation. TNF- and leptin serum levels were also reduced by thalidomide treatment in obese mice. In vitro, the release of basal TNF- and lipopolysaccharide (LPS)-induced MCP-1 was inhibited in 3T3-L1 cells.

question:
The purpose of our study was to investigate the therapeutic potential of Celecoxib for epithelial ovarian cancer, especially on cellular morphological changes, proliferation invasion and epithelial-mesenchymal transition (EMT).', 'The MTT and transwell assays were performed to evaluate the effect of Celecoxib on proliferation and invasion ability of ovarian cancer cell lines, respectively. Western blot was carried out to detect the expression of epithelial phenotypes, E-cadherin and Keratin, and mesenchymal phenotypes, N-cadherin and Vimentin, as well as p-AKT, p-ERK and ZEB1. ZEB1 small-interfering RNA (siRNA) was used to downregulate the expression of ZEB1 to further inquiring into the downstream of Celecoxib-induced EMT.', 'Cellular morphological assessment revealed that both A2780 and SKOV3 cells gradually appeared in the morphology of mesenchymal cells after Celecoxib treatment. The MTT assay demonstrated that celecoxib had no effect on cell proliferation. Transwell assay showed that Celecoxib significantly increased the cell invasion ability. Western blot data proved that the expression of E-cadherin and keratin was elevated, whereas the expression of N-cadherin and Vimentin was decreased in a dose-dependent manner compared with the untreated cells, the expression of p-AKT, p-ERK and ZEB1 was also obviously elevated. However, ZEB1 siRNA reversed Celecoxib-induced E-cadherin expression and N-cadherin expression, as well as cellular invasiveness.
