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: Recent research suggests that preintervention functional magnetic resonance imaging (fMRI) data may predict weight loss outcomes among patients who participate in a behavioral weight loss plan. No study has examined whether presurgical brain activation can predict outcomes following bariatric surgery.', 'The aim of the present study was to determine if brain activations during a presurgical fMRI food-motivation paradigm are associated with weight loss 3 and 6 months following laparoscopic adjustable gastric banding (LAGB). Nineteen participants viewed food and nonfood pictures from a well-established food motivation paradigm during an fMRI scanning session before LAGB surgery. Weight was assessed presurgery and 3 and 6 months postsurgery; data for all participants was available at each time point. fMRI data were analyzed using the BrainVoyager QX statistical package. Whole brain voxelwise correlations of presurgery (food-nonfood) brain activation and weight, corrected for multiple comparisons, were performed to analyze the relationship between presurgical brain activation and subsequent weight loss. The settings were a medical university brain imaging center and 2 surgical weight loss centers in a major metropolitan area.', 'Increased activity in frontal regions associated with cognitive control (medial, middle, superior frontal gyrus) and posterior cingulate cortex was associated with weight loss following LAGB.

Q: Matrix Metalloproteinase-26 (MMP-26) is the smallest member of matrix metalloproteinase (MMP) family that functions mainly in the extracellular milieu to cleave the extracellular matrix proteins. It is expressed in various cell types of placenta, but its function in placentation has been poorly understood. Considering the existence of a unique cysteine switch sequence in MMP-26 protein sequence, as well as the evidence in cancer cells indicating the digestion of the NH2-terminal domain of ERβ by MMP-26, we hypothesize that MMP-26 may have specific intracellular activity in human placental trophoblast cells.', 'This study aimed to identify the intracellular binding partners of MMP-26 and investigate how MMP-26 is involved in placentation through the interactions with its partners.', 'Yeast two-hybrid system was employed to screen potential binding partners of MMP-26 in human placenta. Immunoprecipitation and immunofluorescence assays were conducted to verify the interactions between MMP-26 and the binding partners. HEK293T and HTR8/SVneo cell lines were used as in vitro models to investigate the roles of the interaction between MMP-26 and its binding partner on cell behaviors.', 'RESULTS of yeast two-hybrid assay, immunoprecipitation, and immunofluorescence assays revealed that MMP-26 could bind to growth differentiation factor 15 (GDF15) in the intracellular milieu. The binding of MMP-26 to GDF15 was responsible for the processing and maturation of pro-GDF15, and the process was dependent on the enzymatic activity of MMP-26. In human placental trophoblast cells, MMP-26 could facilitate the pro-apoptotic effect of GDF15.

Q: Somatic cells can be reprogrammed to induced-pluripotent stem cells (iPSCs) by introducing few reprogramming factors, which challenges the long held view that cell differentiation is irreversible. However, the mechanism of induced pluripotency is still unknown.', 'Inspired by the phenomenological reprogramming model of Artyomov et al (2010), we proposed a novel Markov model, stepwise reprogramming Markov (SRM) model, with simpler gene regulation rules and explored various properties of the model with Monte Carlo simulation. We calculated the reprogramming rate and showed that it would increase in the condition of knockdown of somatic transcription factors or inhibition of DNA methylation globally, consistent with the real reprogramming experiments. Furthermore, we demonstrated the utility of our model by testing it with the real dynamic gene expression data spanning across different intermediate stages in the iPS reprogramming process.', 'The gene expression data at several stages in reprogramming and the reprogramming rate under several typically experiment conditions coincided with our simulation results. The function of reprogramming factors and gene expression change during reprogramming could be partly explained by our model reasonably well.
