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: Fructus mume (F. mume) has been used as a traditional treatment for ulcer, cough, and digestive problems for many years in Asian countries. Previous studies have demonstrated that F. mume extracts alleviate cognitive deficits in rats with chronic cerebral hypoperfusion and in mice with scopolamine treatments. The present experiment was conducted to examine the effects of F. mume on cognitive impairments in 5XFAD transgenic mice with five familial Alzheimer's disease (AD) mutations.", 'F. mume was administered daily to 5XFAD mice at 12 weeks of age and continued for 90 days. Cognitive function was evaluated using a spatial memory version of the Morris water maze task, the object/location novelty recognition test, and contextual fear conditioning at 24 weeks of age. To elucidate the possible mechanisms underlying the memory improving effects of F. mume in 5XFAD mice, we examined alterations in hippocampal cholinergic function.', 'Vehicle-treated 5XFAD mice exhibited hippocampus-dependent memory impairments compared with non-transgenic littermates, which was reversed in F. mume-treated 5XFAD mice. In addition, reduced hippocampal choline acetyltransferase (ChAT) levels in 5XFAD mice were reversed by F. mume treatment, indicating that F. mume enhances the effects of cholinergic neuronal function.

Output: Do fructus mume extracts alleviate cognitive impairments in 5XFAD transgenic mice?


Input: Consider Input: Thailand has the lowest incidence of gastric cancer in the world. Helicobacter pylori infection, a low serum pepsinogen I/II ratio, and interleukin (IL)-1beta-511 polymorphisms are suspected to be risk factors for gastric cancer.', 'A total of 167 Thais, comprising 56 cancer patients and 111 volunteers without cancer, underwent an esophagogastroduodenoscopic examination and three fixed-point biopsies; a cancer tissue biopsy was also done, and blood samples were collected. The subjects without cancer were divided into normal subjects and chronic gastritis patients. IL-1beta-511 polymorphisms were analyzed by polymerase chain reaction-restriction fragment length polymorphism, and the serum levels of pepsinogen I and II were determined by a radioimmunoassay. Helicobacter pylori IgG antibody and tissue pathology were tested in all groups.', 'The pepsinogen I/II ratio was significantly lower in the gastric cancer group than in the normal and chronic gastritis groups [odds ratio (OR), 2.3; 95% confidence interval (CI), 1.10-4.80; P = 0.025]. Gastric cancer patients were positive for the H. pylori IgG antibody more frequently than negative (OR, 2.946; 95% CI, 1.4-6.39; P = 0.005). However, only 15 (27%) cancer patients were both positive for H. pylori IgG antibody and had low serum pepsinogen I/II. The C/C genotype was found more frequently in the gastric cancer group than in the group with a normal gastric mucosa (OR, 0.64; 95% CI, 0.50-0.81; P = 0.014).

Output: Are helicobacter pylori infection in combination with the serum pepsinogen I/II ratio and interleukin-1beta-511 polymorphisms independent risk factors for gastric cancer in Thais?


Input: Consider Input: Gastric cancer is the third leading cause of cancer-related deaths in the world with high mortality rate due to the lack of markers in early detection and effective therapies. MicroRNAs (miRNAs), a critical part of epigenetic regulations in tumor, have been shown to be closely related to the initiation, development, invasion, metastasis and prognosis of gastric cancer. The present study aims to investigate the expression of miR-1290 in gastric tumor cells and to elucidate the target gene of miR-1290 in SGC-7901 gastric cancer cells.', 'The fluorescence in situ hybridization, real time PCR and Western blot were used to investigate the expression of miR-1290 in gastric tumor cells and clinical gastric tumor samples. The effect of miR-1290 expression on gastric tumor cells was studied using Synthetic miR-1290 inhibitor transfection, in vitro wound healing assay and flow cytometry analysis. Bioinformatics and Luciferase reporter assay were used to predict and validate the target gene of miR-1290.', 'Our results revealed that miR-1290 was highly expressed in SGC-7901 gastric cancer cells as well as in clinical gastric cancer samples, which was correlated with clinical stages, depth of invasion and lymph node metastasis. Synthetic miR-1290 inhibitor transfection significantly inhibited the proliferation and migration of SGC-7901 cells. Bioinformatics analysis and luciferase reporter assay suggested that miR-1290 functioned in gastric cancer cells by targeting FOXA1 gene.


Output: Does sMicroRNA-1290 inhibit cells proliferation and migration by targeting FOXA1 in gastric cancer cells?
