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.

[EX Q]: Temporal lobe epilepsy (TLE) with hippocampal sclerosis has widespread effects on structural and functional connectivity and often entails cognitive dysfunction. EEG is mandatory to disentangle interactions in epileptic and physiological networks which underlie these cognitive comorbidities. Here, we examined how interictal epileptic discharges (IEDs) affect cognitive performance.', 'Thirty-four patients (right TLE=17, left TLE=17) were examined with 24-hour video-EEG and a battery of neuropsychological tests to measure intelligence quotient and separate frontal and temporal lobe functions. Hippocampal segmentation of high-resolution T1-weighted imaging was performed with FreeSurfer. Partial correlations were used to compare the number and distribution of clinical interictal spikes and sharp waves with data from imagery and psychological tests.', 'The number of IEDs was negatively correlated with executive functions, including verbal fluency and intelligence quotient (IQ). Interictal epileptic discharge affected cognitive function in patients with left and right TLE differentially, with verbal fluency strongly related to temporofrontal spiking. In contrast, IEDs had no clear effects on memory functions after corrections with partial correlations for age, age at disease onset, disease duration, and hippocampal volume.

[EX Q]: Several studies have reported that ventriculoperitoneal shunt insertion for treatment of normal-pressure hydrocephalus results in improvement of gait and, less frequently, improvement of cognition. We sought to identify the demographic factors associated with cognitive improvement after shunt insertion to improve assessment of prognosis for cognitive gains with treatment.', 'We report cognitive testing before and after ventriculoperitoneal shunt insertion in 36 patients with normal pressure hydrocephalus, who previously had improvement of any clinical symptom--gait, urinary incontinence, cognition--after a diagnostic trial of continuous cerebrospinal fluid drainage.

[EX Q]: Metastasis is a primary cause of colorectal cancer (CRC)-related death, and cancer stem cells (CSCs) are thought to be majorly responsible for initiating metastatic behaviors. Doublecortin-like kinase 1 (DCLK1) was recently discovered to be a marker for gastrointestinal CSCs. Here, we aimed to explore whether DCLK1 is associated with CRC metastasis through clinical and in vitro investigations.', 'The expression levels of DCLK1 mRNA and protein in human CRC tissues were analyzed through quantitative RT-PCR and immunohistochemistry staining, respectively. Human CRC cell line SW480 was selected to explore the effect of DCLK1 overexpression on cell migration and invasion. Besides, the associations between DCLK1 and epithelial-mesenchymal transition (EMT) were determined.', 'Compared to normal colorectal tissues, DCLK1 expression was significantly up-regulated in human CRC tissues and correlated well with high lymphatic metastasis and poor prognosis in patients. DCLK1 expression was inversely associated with overall survival in CRC patients. Overexpression of DCLK1 in SW480 cells markedly promoted cell migration and invasion. Furthermore, we validated that DCLK1 could facilitate EMT in cancer cells by up-regulation of the mesenchymal markers Vimentin and ZEB1 and down-regulation of the epithelial marker E-cadherin in SW480 cells.
