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.

Context: Cells of the myeloid lineage comprise a very heterogeneous population with many phenotypes and functional activities including macrophages and dendritic cells. To investigate the status, differentiative potential and lineage commitment of monocytic cells in systemic lupus erythematosus (SLE) patients, this study isolated and cultured peripheral blood monocytes from patients and healthy donors.', 'Monocytes were isolated by gradient centrifugation and adherence to plastic dishes. The cells were then cultured for three days, partially supplemented with GM-CSF and interleukin 4 (IL4) to obtain dendritic cells. The differentiation status was monitored by the expression of surface markers using flow cytometry and cytokine secretion.', 'Monocytes from SLE patients expressed significantly lower numbers of the monocytic marker CD14 and HLA-DR while secreting significantly more tumour necrosis factor alpha (TNFalpha) than monocytes from healthy donors. The addition of GM-CSF and IL4 resulted in an inhibition of TNFalpha secretion, but was not sufficient to generate monocytederived dendritic cells.
Answer: Monocytes from SLE patients are severely altered in phenotype and function and have a limited differentiation flexibility towards the accessory type of monocytic cells.

Ex Output:
Are monocytes from systemic lupus erythematous patients severely altered in phenotype and lineage flexibility?

Context: In utero undernutrition is associated with obesity and insulin resistance, although its effects on skeletal muscle remain poorly defined. Therefore, in the current study we explored the effects of in utero food restriction on muscle energy metabolism in mice.', 'We used an experimental mouse model system of maternal undernutrition during late pregnancy to examine offspring from undernourished dams (U) and control offspring from ad libitum-fed dams (C). Weight loss of 10-week-old offspring on a 4-week 40% calorie-restricted diet was also followed. Experimental approaches included bioenergetic analyses in isolated mitochondria, intact (permeabilized) muscle and at the whole body level.', 'U have increased adiposity and decreased glucose tolerance compared to C. Strikingly, when U are put on a 40% calorie-restricted diet they lose half as much weight as calorie-restricted controls. Mitochondria from muscle overall from U had decreased coupled (state 3) and uncoupled (state 4) respiration and increased maximal respiration compared to C. Mitochondrial yield was lower in U than C. In permeabilized fiber preparations from mixed fiber-type muscle, U had decreased mitochondrial content and decreased adenylate-free leak respiration, fatty acid oxidative capacity and state 3 respiratory capacity through complex I. Fiber maximal oxidative phosphorylation capacity did not differ between U and C but was decreased with calorie restriction.
Answer: Our results reveal that in utero undernutrition alters metabolic physiology through a profound effect on skeletal muscle energetics and blunts response to a hypocaloric diet in adulthood. We propose that mitochondrial dysfunction links undernutrition in utero with metabolic disease in adulthood.

Is low birth weight associated with adiposity , impaired skeletal muscle energetics and weight loss resistance in mice?

Context: To investigate the associations between C-reactive protein (CRP), homocysteine levels, use of hormone therapy (HT) and other factors.', "A 12-year prospective study of 438 Australian-born women (Melbourne Women's Midlife Health Project), who at baseline were aged 45-55 years, had menstruated in the previous 3 months and were not taking HT. Fasting blood was collected in the 11th follow-up year for CRP, homocysteine, estradiol and follicle stimulating hormone (FSH) levels. Physical measurements and face-to-face interviews obtained information on health and lifestyle variables.", 'A total of 258 women (mean age 60 years) participated in the 11th follow-up year. Multiple regression analysis found that CRP levels were positively associated with body mass index (p < 0.001), HT use (p < 0.01), and negatively associated with statin use (p < 0.005) and exercising (p < 0.05). In postmenopausal women currently not using HT (n = 173) and after adjusting for body mass index, exercise and smoking, CRP was negatively associated with FSH levels (beta = -0.32, p < 0.05). Homocysteine levels were positively associated with smoking (p < 0.001) and negatively associated with HT use (p < 0.05).
Answer: In middle-aged Australian-born women, HT use was associated with increased CRP and decreased homocysteine levels. High CRP levels were also associated with high relative weight, low exercise levels and no statin medication.
