Given a passage with a context and an answer, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Question: Context: Surfactant protein (SP) D shares target cells with the proinflammatory cytokine TNF-alpha, an important autocrine stimulator of dendritic cells and macrophages in the airways.', 'We sought to study the mechanisms by which TNF-alpha and SP-D can affect cellular components of the pulmonary innate immune system.', 'Cytokine and SP-D protein and mRNA expression was assessed by means of ELISA, Western blotting, and real-time PCR, respectively, by using in vivo models of allergic airway sensitization. Macrophage and dendritic cell phenotypes were analyzed by means of FACS analysis. Maturation of bone marrow-derived dendritic cells was investigated in vitro.', 'TNF-alpha, elicited either by allergen exposure or pulmonary overexpression, induced SP-D, IL-13, and mononuclear cell influx in the lung. Recombinant IL-13 by itself was also capable of enhancing SP-D in vivo and in vitro, and the SP-D response to allergen challenge was impaired in IL-13-deficient mice. Allergen-induced increase of SP-D in the airways coincided with resolution of TNF-alpha release and cell influx. SP-D-deficient mice had constitutively high numbers of alveolar mononuclear cells expressing TNF-alpha, MHC class II, CD86, and CD11b, characteristics of proinflammatory, myeloid dendritic cells. Recombinant SP-D significantly suppressed all of these molecules in bone marrow-derived dendritic cell cultures.
Answer: TNF-alpha can contribute to enhanced SP-D production in the lung indirectly through inducing IL-13. SP-D, on the other hand, can antagonize the proinflammatory effects of TNF-alpha on macrophages and dendritic cells, at least partly, by inhibiting production of this cytokine.

Answer: Does surfactant protein D inhibit TNF-alpha production by macrophages and dendritic cells in mice?


Question: Context: Hyaluronic acid binding protein 1 (HABP1), a family of proteins interacting with hyaluronan (HA), had been associated with cell adhesion and tumor invasion. The aim of this study was to investigate the correlation between clinicopathologic factors and patient survival time with the expression of HABP1 in breast cancer patients.', 'Expression of HABP1 mRNA and protein were detected with real-time quantitative PCR and immunohistochemical staining in 63 breast cancer and non-cancerous matched tissues.', "The mRNA expression level of HABP1 was unrelated to the patient's age, tumor size, histological grade, TNM stage. However, it proved to be positively related to axillary nodes metastasis (P = 0.008). Furthermore, it was shown that the survival rate of patients with low HABP1 expression was significantly higher than that of patients with high HABP1 expression (P = 0.025). Multivariate analysis revealed that HABP1 mRNA expression level was a significant factor for predicting prognosis (P = 0.022). The immunohistochemistry results showed that the expression level of HABP1 in breast cancer cells was higher than that in normal breast cells.
Answer: HABP1 might be an independent predictive factor for breast cancer prognosis and up-regulation of HABP1 might play an important role in the metastasis of breast cancer.

Answer: Is increased expression of hyaluronic acid binding protein 1 correlated with poor prognosis in patients with breast cancer?


Question: Context: Despite concerns about increased sexual harassment and assault after the 2013 legislation repealing the ban on women in combat, little research has examined military factors that could prevent sexual harassment and assault during deployment. This study examined whether unit support, which reflects the quality of service members' relationships within their unit, protects against sexual harassment and assault during deployment.", 'Participants were 1,674 Ohio Army National Guard service members who reported at least one deployment during a telephone survey conducted in 2008 and 2009. Participants completed measures of sexual harassment/assault, unit support, and psychosocial support. Logistic regression was used to model odds of sexual harassment/assault.', 'Approximately 13.2% of men (n = 198) and 43.5% of women (n = 74) reported sexual harassment, and 1.1% of men (n = 17) and 18.8% of women (n = 32) reported sexual assault during their most recent deployment. Greater unit support was associated with decreased odds of sexual harassment and assault.
Answer: A substantial proportion of men and women reported sexual harassment/assault. Greater unit support was associated with diminished odds of sexual harassment/assault during deployment. Programming designed to improve unit cohesion has the potential to reduce sexual harassment and assault.

Answer:
Does unit support protect against sexual harassment and assault among national guard soldiers?
