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: Hippocampal neurodegeneration is one of the hallmarks in neurological and neurodegenerative diseases such as temporal lobe epilepsy and Alzheimer disease. Human embryonic kidney (HEK) cells are a mixed population of cells, including neurons, and their conditioned medium is enriched with erythropoietin (EPO). Because EPO is a known neuroprotectant, we hypothesized that infusion of HEK cells or HEK-conditioned medium (HEK-CM) may provide neuroprotection against kainic acid (KA)-induced hippocampal damage in mice.', 'Adult CF1 mice were treated with KA to induce hippocampal damage. On 3rd and 5th days after KA treatment, HEK cells or HEK-CM was infused intravenously through the tail vein. On the 7th and 8th days after KA treatment, all groups of mice were subjected to cognitive and depression assessment by use of a novel object recognition test and a forced swim test, respectively. Subsequent to this assessment, mice were killed and the brain samples were used to assess the histopathology and messenger RNA expression for EPO and B-cell lymphoma-2 (Bcl-2).', 'We found that infusion of HEK cells/HEK-CM improves cognitive function and alleviates symptoms of depression. Histological assessment demonstrates complete neuroprotection against KA-mediated excitotoxicity, and the hippocampal cytoarchitecture of HEK cells/HEK-CM treated mice was comparable to normal control mice. HEK cells/HEK-CM treatment could provide neuroprotection by upregulating the endogenous EPO and Bcl-2 in KA-treated mice.

Q: Regulation of the cytoskeleton is a central feature of cell migration. The formin family of proteins controls the rate of actin nucleation at its barbed end. Thus, formins are predicted to contribute to several important cell processes such as locomotion, membrane ruffling, vesicle endocytosis, and stress fiber formation and disassociation.', 'In this study we investigated the functional role of Formin1-isoform4 (Fmn1-IV) by using genetically null primary cells that displayed augmented protrusive behaviour during wound healing and delayed cell spreading. Cells deficient of Fmn1-IV also showed reduced efficiency of focal adhesion formation. Additionally, we generated an enhanced green fluorescence protein (EGFP)-fused Fmn1-IV knock-in mouse to monitor the endogenous subcellular localization of Fmn1-IV. Its localization was found within the cytoplasm and along microtubules, yet it was largely excluded from adherens junctions.

Q: Helicobacter pylori infection is now accepted as the most common cause of chronic active gastritis and peptic ulcer disease. The etiologies of many infectious diseases have been attributed to specific or clonal strains of bacterial pathogens. Polymerase chain reaction (PCR) amplification of DNA between repetitive DNA sequences, REP elements (REP-PCR), has been utilized to generate DNA fingerprints to examine similarity among strains within a bacterial species.', 'Genomic DNA from H. pylori isolates obtained from 70 individuals (39 duodenal ulcers and 31 simple gastritis) was PCR-amplified using consensus probes to repetitive DNA elements. The H. pylori DNA fingerprints were analyzed for similarity and correlated with disease presentation using the NTSYS-pc computer program.', 'Each H. pylori strain had a distinct DNA fingerprint except for two pairs. Single-colony DNA fingerprints of H. pylori from the same patient were identical, suggesting that each patient harbors a single strain. Computer-assisted cluster analysis of the REP-PCR DNA fingerprints showed two large clusters of isolates, one associated with simple gastritis and the other with duodenal ulcer disease.
