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.

Input: Consider Input: Hepatic myofibroblasts are relevant for pathogenesis of S. mansoni infection. In normal liver, these perisinusoidal cells are quiescent, express the lipocyte phenotype, and are located in the Disse's space, being the major site of vitamin A storage. When activated, they convert to myofibroblasts and contribute to granulomatous and diffuse liver fibrosis. In the present work, we observed that myofibroblasts obtained from granulomatous periovular inflammatory reactions in schistosome-infected mice (GR-MF) produce in vitro immunomodulatory cytokines for eosinophil activation: IL-5 and eotaxin.", 'The secretory activity of GR-MF was detected after TGF-β and IL-13 stimulation using 2D and 3D cell culture systems. In a mixed co-culture system using GR-MF with hematopoietic bone marrow cells from infected mice, we observed eosinophil survival that was dependent upon IL-5 and eotaxin, since antibodies against this cytokines decreased eosinophil population, as measured by eosinophil peroxidase activity.

Output: Are hepatic myofibroblasts derived from Schistosoma mansoni-infected mice a source of IL-5 and eotaxin : controls of eosinophil populations in vitro?


Input: Consider Input: To examine the effect of TRIB3 on endoplasmic reticulum stress induced β-cell apoptosis and to investigate the mechanism with a specific emphasis on the role of NF-κB pathway.', 'We investigated the effect of TRIB3 on ER stress-induced β-cell apoptosis in INS-1 cells and primary rodent islets. The potential role of TRIB3 in ER stress inducer thapsigargin (Tg)-induced β-cell apoptosis was assessed using overexpression and siRNA knockdown approaches. Inducible TRIB3 β-cells, regulated by the tet-on system, were used for sub-renal capsule transplantation in streptozotocin (STZ)-diabetic mice, to study the effect of TRIB3 on ER stress-induced β-cell apoptosis in vivo. Apoptosis was determined by TUNEL staining both in vivo and in vitro, while the molecular mechanisms of NF-κB activation were investigated.', 'TRIB3 was induced in ER-stressed INS-1 cells and rodent islets, and its overexpression was accompanied by increased β-cell apoptosis. Specifically, TRIB3 overexpression enhanced Tg-induced INS-1 derived β-cell apoptosis both in vitro and in sub-renal capsular transplantation animal model. Additionally, knockdown of Trib3 blocked Tg-induced apoptosis. Mechanistically, the induction of TRIB3 during ER stress resulted in the activation of NF-κB and aggravated INS-1 derived β-cell apoptosis, while inhibiting the NF-κB pathway significantly abrogated this response and prevented β-cell apoptosis, both in vitro and in sub-renal capsular transplantation animal model.

Output: Does tRIB3 alter endoplasmic reticulum stress-induced β-cell apoptosis via the NF-κB pathway?


Input: Consider Input: To investigate whether angiopoietin-2 (Ang2) and vascular endothelial growth factor (VEGF) are implicated in the hypoxemic resuscitation from hemorrhagic shock.', 'Twenty rabbits were subjected to hemorrhagic shock after blood exsanguination; resuscitation was performed by infusion of the shed blood in ten rabbits under normoxemic conditions (NormoxRes) and in 10 under hypoxemic conditions (HypoxRes); four rabbits were subjected to sham operation. Serum was drawn at serial time intervals; serum was applied for stimulation of U937 monocytes.', 'Serum concentrations of Ang2 were higher in the NormoxRes group compared to the HypoxRes group at 90 min (p: 0.049) and at 120 min (p: 0.028). Serum concentrations of VEGF did not differ between groups. Concentrations of VEGF in the supernatants of U937 stimulated with sera of all groups were below detection limit. The wet to dry lung ratio of the HypoxRes group was significantly lower than the NormoxRes group (p<0.0001).


Output: Is hypoxemic resuscitation after hemorrhagic shock accompanied by reduced serum levels of angiopoietin-2?
