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]: The combined effects of Human papillomavirus (HPV) and Herpes simplex type 1 (HSV-1) infections and their effects on cancer cell radioresistance are unexplored.', 'An HPV16-positive hypopharyngeal carcinoma cell line (UD-SCC-2) was infected with wt-HSV-1 at low multiplicity of infection (MOI) and irradiated with 2 Gy at 24 h postinfection. Viability assays and quantitative reverse-transcriptase PCR for HPV16 E6, E7, nuclear factor kappa B1, B-cell CLL/lymphoma 2 (BCL2), and caspases 3, 8 and 9 at 24, and 72 h, as well as immunocytochemistry for BCL2, caspase 3, cyclin E, mouse double minute 2 homolog (MDM2), HSV-1 and Ki-67 were performed at 144 h postirradiation.', 'At 144 h, cell viability was significantly lowered by irradiation only in uninfected cells. Infection combined with irradiation resulted in increased expression of E6, E7, BCL2 and NF-κB1 at 144 h. Simultaneously, E6 and E7 were down-regulated in non-irradiated infected cells. Irradiation and infection with 0.00001 MOI separately up-regulated caspase 3 but infection with 0.0001 MOI halved its expression in irradiated cells.

[Q]: From 1984 to 2006, studies of sleep in patients with interstitial lung disease revealed disturbed sleep, frequent nocturnal desaturations, nocturnal cough, and obstructive sleep apnea (OSA). Our goal was to analyze OSA in an outpatient population of stable patients with idiopathic pulmonary fibrosis (IPF).', 'Patients with IPF who had been followed up in the Vanderbilt Pulmonary Clinic were asked to participate. All patients were given a diagnosis of IPF by the 2000 American Thoracic Society consensus statement criteria. Subjects completed an Epworth sleepiness scale (ESS) questionnaire and a sleep apnea scale of sleep disorders questionnaire (SA-SDQ) before undergoing nocturnal polysomnography (NPSG). OSA was defined as an apnea-hypopnea index (AHI) of > 5 events per hour.', 'Fifty subjects enrolled and completed a NPSG. The mean age was 64.9 years, and the mean BMI was 32.3. OSA was diagnosed in 88% of subjects. Ten subjects (20%) had mild OSA (AHI, 5 to 15 events per hour), and 34 subjects (68%) had moderate-to-severe OSA (AHI, > 15 events per hour). Only 6 subjects (12%) had a normal AHI. One patient was asymptomatic as determined by ESS and SA-SDQ, but had an AHI of 24 events per hour. The sensitivity of the ESS was 75% with a specificity of 15%, whereas the SA-SDQ had a sensitivity of 88% with a specificity of 50%. BMI did not correlate strongly with AHI (r = 0.30; p = 0.05).

[Q]: In the fruit fly Drosophila, the Inscuteable protein localises to the apical cell cortex in neuroblasts and directs both the apical-basal orientation of the mitotic spindle and the basal localisation of the protein determinants Numb and Prospero during mitosis. Asymmetric localisation of Inscuteable is initiated during neuroblast delamination by direct binding to Bazooka, an apically localised protein that contains protein-interaction motifs known as PDZ domains. How apically localised Inscuteable directs asymmetric cell divisions is unclear.', 'A novel 70 kDa protein called Partner of Inscuteable (Pins) and a heterotrimeric G-protein alpha subunit were found to bind specifically to the functional domain of Inscuteable in vivo. The predicted sequence of Pins contained tetratrico-peptide repeats (TPRs) and motifs implicated in binding Galpha proteins. Pins colocalised with Inscuteable at the apical cell cortex in interphase and mitotic neuroblasts. Asymmetric localisation of Pins required both Inscuteable and Bazooka. In epithelial cells, which do not express inscuteable, Pins was not apically localised but could be recruited to the apical cortex by ectopic expression of Inscuteable. In pins mutants, these epithelial cells were not affected, but neuroblasts showed defects in the orientation of their mitotic spindle and the basal asymmetric localisation of Numb and Miranda during metaphase. Although localisation of Inscuteable in pins mutants was initiated correctly during neuroblast delamination, Inscuteable became homogeneously distributed in the cytoplasm during mitosis.
