Given a passage, 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.

Q: GM-CSF has broad clinical applicability as a potent myelopoietic stimulator. However, its function is not restricted to the myelopoietic system and several observations suggest that GM-CSF may interfere with the hemostatic balance. In order to assess whether GM-CSF has any influence on hemostasis, we evaluated some coagulative and fibrinolytic parameters in patients treated with GM-CSF following chemotherapy.', 'Fibrinolytic activity (FA), fibrinogen and D-dimer were evaluated before and after high-dose cyclophosphamide in 6 patients additionally treated with GM-CSF and in 5 control patients; moreover, tissue plasminogen activator (tPA) was assayed in those treated with GM-CSF. Comparative in vitro analysis was performed on cultured endothelial cells before and after exposure to GM-CSF.', 'Control patients showed a significant decrease in plasma FA after chemotherapy compared to basal values (FA/mm2: 15.6 +/- 2.1 at day + 2 and 20.8 +/- 19 at day + 4 vs. 103.8 +/- 64.2 at day 0; p < 0.005); conversely, no FA reduction was observed in GM-CSF-treated subjects. In this latter group a marked increase in tPA antigen was seen, consistent with enhanced FA. No significant changes in plasma D-dimer and fibrinogen values were detected in the two groups. tPA, urokinase-type plasminogen activator, PAI-1 and procoagulant activity were evaluated in vitro on cultured human endothelial cells and found to be unchanged following GM-CSF addition.

Q: Testicular germ cell tumours are the most common malignancies in young males. Molecular biology studies of these tumours are often contradictory. Two histological groups, seminoma and non-seminoma, differ both morphologically and in malignant behaviour. Although a common cytogenetic feature is seen, namely the amplification of the 12p chromosomal region, the development mechanisms of less aggressive seminomas and more aggressive non-seminomas are unknown.', 'Occurrence of structural genetic alterations was analyzed in 18 seminomas and 22 non-seminomas for genes involved in the malignant tumour phenotype: cadherin 1, Type 1, E-cadherin (Epithelial), CDH1; adenomatous polyposis coli, APC; NME/NM23 nucleoside diphosphate kinase 1, NME1; tumour protein P53, TP53; cyclin-dependent kinase inhibitor 2A, CDKN2A; retinoblastoma 1, RB1; RAD51 recombinase, RAD51; mutS homolog 2, MSH2; MutL homolog 1, MLH1; breast cancer 1, early onset, BRCA1; BCL2-Associated X Protein, BAX; ATP-Binding Cassette, Sub-Family G (WHITE), Member 2, ABCG2. Genetic alterations, loss of heterozygosity and microsatellite instability, were analyzed using restriction fragment or microsatellite repeat length polymorphisms.', 'A difference in genetic alteration occurrence between seminomas and non-seminomas was observed.

A: Do histological groups of human postpubertal testicular germ cell tumours harbour different genetic alterations?

Q: This large cross-sectional, multi-centre study evaluated the association of body composition measurements by a novel dual frequency bioimpedance device (BIA-ACC) with chronic stress/inflammation biomarkers and the presence of medically unexplained symptoms (MUS).', 'Participants were adult Caucasians of both sexes and included 10,416 lean subjects with no MUS (Group A), 58,710 lean subjects with MUS (Group B) and 30,445 overweight/obese subjects with no MUS and excessive fat mass (FM) (Group C).', 'Total body extracellular water (ECW) was higher, while intracellular water (ICW) was lower in Group B than both other groups (P < 0.01). Group A had significantly lower FM and higher skeletal mass (SK) and phase angle (PA) than Group B and lower circulating high sensitivity (hs) CRP levels than both other groups. hsCRP was higher in Group C than Group A though (P < 0.01). Salivary cortisol in Group B was lower in the morning and higher in the evening than both other groups (P < 0.001), indicating circadian rhythm obliteration or reversal in this group. ECW correlated positively with serum hsCRP and 8 p.m. salivary cortisol, but negatively with 8 a.m. salivary cortisol, while PA correlated positively with 8 a.m. and negatively with 8 p.m. salivary cortisol and serum hsCRP. Both 8 a.m. and 8 p.m. salivary cortisol and serum hsCRP were associated with the presence of MUS and BIA-ACC measurements, including ECW, ICW, FM, SK and PA.
