In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Input: Consider Input: Context: Hypoxia is associated with human non-small cell lung cancers (NSCLC), which are highly resistant to chemotherapy. The hypoxia inducible factor (HIF) as a transcription factor in response to hypoxia indicates that it could be a novel, tumor-specific target for anticancer therapy. We hypothesized that disruption of HIF pathway through lentiviral vector-mediated HIF-1alpha RNA interference (RNAi) could reverse the hypoxia-induced resistance to chemotherapy.', 'We transfected Human NSCLC cell lines, SPCA1 and A549 with HIF-1alpha specific RNAi lentiviral vectors as well as controls. HIF-1alpha silenced cells [SPCA1/HIF-1alpha(-) and A549/HIF-1alpha(-)] were screened by blasticidin. They were incubated in 19 or 0.5% O2 for 16 h followed by the assessment of chemosensitivity to cisplatin and doxorubicin with MTT and clonogenic assays. Quantitative RT-PCR and Western blot analysis were used to detect the expressions of HIF-1alpha mRNA and protein, respectively. Moreover, flow cytometry was used to monitor the expression of P-glycoprotein.', 'Exposure of SPCA1 and A549 cells to 0.5% O2 significantly increased resistance to cisplatin and doxorubicin, in contrast to cells incubated in normoxia. Transduction of SPCA1 with HIF-1alpha RNAi vector resulted in sequence specific silencing with 87.2 and 84.6% decreases of HIF-1alpha mRNA transcription and 97.3 and 94.8% of protein expressions in normoxia and hypoxia, respectively. Correspondingly, they are 89.2, 89.9% and 97.2, 88.4% decreases in A549 cells. Hypoxia-induced resistance to cisplatin and doxorubicin were reversed in SPCA1/HIF-1alpha(-) and A549/HIF-1alpha(-) cells. There was no significant P-glycoprotein increase induced by hypoxia in NSCLC cells.\Question: Is hypoxia-induced resistance to cisplatin and doxorubicin in non-small cell lung cancer inhibited by silencing of HIF-1alpha gene?

Output: Our studies demonstrated that hypoxia-induced chemoresistance to cisplatin and doxorubicin in NSCLC cells is through the HIF pathway. MDR1 regulation may not be involved in hypoxia-induced chemoresistance. Combining delivery of HIF-1alpha RNAi lentiviral vector with cisplatin-related chemotherapy regimens may enable us to develop more effective strategy for NSCLC therapy.

Input: Consider Input: Context: Profiles of allergic sensitization are poorly documented in infancy. Relations between early sensitization and allergic morbidity need to be clarified.', 'This study dealt with children involved in the Pollution and Asthma Risk: an Infant Study (PARIS), a population-based prospective birth cohort. Allergic sensitization to twelve food and four inhalant allergens was assessed at 18months and defined by a specific immunoglobulin E (IgE) level 0.35kU', 'Sensitization to any allergen concerned 13.6% of infants. By cluster analysis, 1525 infants were grouped into three profiles: 89.2% not or rarely sensitized (only 3.7% of sensitized), 9.2% mainly sensitized to one or few allergens (45.2% of monosensitized and 45.9% of paucisensitized) and 1.6% all polysensitized. The prevalence of doctor-diagnosed asthma, rhinitis, eczema, food allergy and multimorbidity at 2years increased from profile one to profile three (p-trend <0.001). At 6years, symptoms of current asthma, rhinitis, eczema and multimorbidity were significantly more frequent in the last two profiles.\Question: Is early polysensitization associated with allergic multimorbidity in PARIS birth cohort infants?

Output: This study highlights, as early as 18months of age, three profiles of increasing severity with regard to allergic sensitization and diseases. These profiles also differ in terms of allergic morbidity at 6years. Early sensitization can predict allergic multimorbidity in childhood, and in the case of early polysensitization, multimorbidity is more frequent as soon as infancy.

Input: Consider Input: Context: The aim of this exploratory study was to identify those factors associated with asthma control assessed according to GINA Guidelines.', '809 (56% female) subjects with asthma were recruited consecutively from both specialist and primary care centres. Asthma control was assessed over a 4-week follow-up period using a composite measure. A multivariate analysis was performed, in which asthma control was included as the dependent variable and several explanatory variables were included as independent variables.', 'Analysis performed on the whole population rendered gender (p=0.003), the type of physician (p<0.001), and age group (p<0.001), as significant factors associated with asthma control. In adults, gender (p=0.001), asthma severity (p<0.001), and type of physician (p<0.001) were significant, and only asthma severity was significant (p=0.043) in children.\Question: Are women , patients with severe asthma , and patients attended by primary care physicians , at higher risk of suffering from poorly controlled asthma?
Output: After model adjustment, we suggest that being female, suffering from more severe asthma, or being attended by a primary care physician, could pose a significantly higher risk of having poorly controlled asthma in adults.
