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.

Input: Consider Input: Context: High visceral adipose tissue (VAT) and high liver fat (LF) are associated with the metabolic syndrome and diabetes. We studied changes in these two fat depots during weight loss and analyzed whether VAT and LF at baseline predict the response to lifestyle intervention.', 'One hundred twelve subjects (48 men and 64 women; age, 46 +/- 11 years; BMI, 29.2 +/- 4.4 kg/m(2)) were studied after a follow up-time of 264 +/- 60 (SD) days. Insulin sensitivity was estimated from the oral glucose tolerance test. Body fat depots were quantified using magnetic resonance imaging and spectroscopy.', 'Cross-sectionally high VAT (r = -0.22, p = 0.02) and high LF (r = -0.36, p < 0.0001) were independently associated with low insulin sensitivity. With intervention, BMI (-3.0%), VAT (-12.0%), and LF (-33.0%) were reduced (all p < 0.001). Insulin sensitivity was improved (+17%, p < 0.01). The changes in BMI (r = -0.41), VAT (r = -0.28), and LF (r = -0.39) were associated with the increase in insulin sensitivity (all p < 0.01). High VAT (r = -0.28, p = 0.01) and high LF (r = -0.38, p < 0.01) at baseline were associated with a lesser increase in insulin sensitivity.
Answer: Baseline values and changes in BMI, VAT, and LF are related to changes in insulin sensitivity during lifestyle intervention. Subjects with high VAT and LF have a lower chance of profiting from lifestyle intervention and may require intensified lifestyle prevention strategies or even pharmacological approaches to improve insulin sensitivity.

Output: Are high visceral fat mass and high liver fat associated with resistance to lifestyle intervention?

Input: Consider Input: Context: Cancer cells frequently exhibit resistance to the cytotoxic effect of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). Pretreatment of TRAIL-resistant cells with cisplatin sensitizes them to this ligand. Cisplatin also has been shown to enhance adenoviral transgene expression.', 'This study aims to evaluate the ability of cisplatin to enhance the expression and the cytotoxic effect of the tumor-specific adenoviral vector Ad/gTRAIL, which expresses a green fluorescent protein-TRAIL fusion protein.', 'Cultured cancer cells and normal human cells were infected with Ad/gTRAIL with or without cisplatin pretreatment. Adenoviral transgene expression was determined by using flow cytometry to measure green fluorescent protein fluorescence. Cytotoxicity was measured by using thiazolyl blue tetrazolium bromide assays and an apoptosis enzyme-linked immunosorbent assay kit.', 'Green fluorescent protein-TRAIL fusion protein expression was significantly enhanced by cisplatin pretreatment in cancer cells. Cisplatin treatment before Ad/gTRAIL infection resulted in a 2- to 12-fold increase in green fluorescent protein fluorescence intensity across cancer lines. Although Ad/gTRAIL induced mild cytotoxicity in all cancer lines (inhibitory concentration of 50% values of >500 pfu/cell), pretreatment with cisplatin resulted in a dose-dependent enhancement of Ad/gTRAIL-mediated cytotoxicity, as indicated by the drastic reduction of inhibitory concentration of 50% values to 4 to 42 pfu/cell in all cell lines. There was no cytotoxicity noted in normal cells treated with both cisplatin and Ad/gTRAIL.
Answer: Cisplatin pretreatment enhances Ad/gTRAIL cytotoxicity in malignant cells while not affecting normal cells. The mechanisms underlying this effect might include both enhancement of the susceptibility of cisplatin-treated cells to TRAIL and cisplatin-mediated enhancement of TRAIL expression in Ad/gTRAIL infected cells. These findings provide a rationale for development of Ad/gTRAIL-based therapy for thoracic malignancies.

Output: Does cisplatin enhance apoptosis induced by a tumor-selective adenovirus expressing tumor necrosis factor-related apoptosis-inducing ligand?

Input: Consider Input: Context: Although many factors predictive of patient survival have been reported for lung cancer, no comparative studies have attempted to determine those that are most significant for practical medicine.', 'We conducted a retrospective review of 139 patients who underwent complete resection of adenocarcinomas less than 2 cm in diameter between 1993 and 2000 at the National Cancer Center Hospital (Tokyo, Japan). The MIB-1 labeling index (LI), immunohistochemical staining for carcinoembryonic antigen (CEA), p53, p27, epidermal growth factor receptor (EGFR), phosphorylated-EGFR (pEGFR), Cox-2, neuronatin, gammaH2AX, and thyroid transcription factor-1 (TTF-1), the prevalence of a micropapillary pattern, and the ratio of the bronchioloalveolar cell carcinoma (BAC) or lepidic growth (LG) component were determined, and their significance as prognostic factors for lung adenocarcinoma was compared.', 'Univariate analysis showed that lymph node metastasis (p-N status), BAC/LG component, vascular invasion (p-V status), MIB-1 LI, pEGFR, and CEA were prognostically significant (p-N status: p < 0.0001, BAC/LG: p = 0.0005, p-V status: 0.002, MIB-1 LI: p = 0.005, pEGFR: p = 0.024, and CEA: p = 0.049). Multivariate analysis showed that only p-N status (p = 0.013) was of prognostic significance. However, BAC/LG component (p = 0.051) was a more reliable prognostic factor than p-N status in mixed adenocarcinoma with a BAC/LG component.
Answer: In comparison with other immunohistochemical and histopathologic factors, BAC/LG component is independently and reliably prognostic for small adenocarcinoma of the lung, and, in particular, for the major histologic subtype (adenocarcinoma mixed subtype with BAC/LG), BAC/LG component is more reliably prognostic than lymph node metastasis.
Output: Is bronchioloalveolar carcinoma ( lepidic growth ) component a more useful prognostic factor than lymph node metastasis?
