Input: Consider Input: Context: Formyl peptide receptor 1 (FPR1) as a regulator of innate inflammatory response has been implicated in tumor progression of gliomas. The purpose of the present study was to evaluate the prognostic significance and the ligand-receptor interaction of FPR1 in gastric cancer (GC).', 'FPR1 was immunohistochemically-analyzed in tissue sections originating from 116 GC patients. Reverse transcription-polymerase chain reaction (RT-PCR) was used for the assessment of interaction between FPR1 and the FPR1 ligand annexin A1 (AnxA1) in GC cells.', 'High FPR1 expression was significantly associated with stage IV disease, submucosal invasion, serosal invasion, and clinical outcome of GC. Multivariate analysis showed that high FPR1 expression was an independent risk factor of poor overall survival in GC patients. FPR1 expression increased significantly when AnxA1 overexpression was present in GC cells. A positive feedback regulation of FPR1 was involved in the AnxA1-FPR1 signal transduction.
Answer: FPR1 expression may be used as a novel indicator to predict outcome in GC patients after gastrectomy.

Output: Is formyl Peptide receptor 1 expression associated with tumor progression and survival in gastric cancer?


Input: Consider Input: Context: Chronic stress is generally known to exacerbate the development of numerous neuropsychiatric diseases such as fear and anxiety disorders, which is at least partially due to the disinhibition of amygdala subsequent to the prolonged stress exposure. GABA receptor A (GABAAR) mediates the primary component of inhibition in brain and its activation produces two forms of inhibition: the phasic and tonic inhibition. While both of them are critically engaged in limiting the activity of amygdala, their roles in the amygdala disinhibition subsequent to chronic stress exposure are largely unknown.', 'We investigated the possible alterations of phasic and tonic GABAAR currents and their roles in the amygdala disinhibition subsequent to chronic stress. We found that both chronic immobilization and unpredictable stress led to long lasting loss of tonic GABAAR currents in the projection neurons of lateral amygdala. By contrast, the phasic GABAAR currents, as measured by the spontaneous inhibitory postsynaptic currents, were virtually unaltered. The loss of tonic inhibition varied with the duration of daily stress and the total days of stress exposure. It was prevented by pretreatment with metyrapone to block corticosterone synthesis or RU 38486, a glucocorticoid receptor antagonist, suggesting the critical involvement of glucocorticoid receptor activation. Moreover, chronic treatment with corticosterone mimicked the effect of chronic stress and reduced the tonic inhibition in lateral amygdala of control mice. The loss of tonic inhibition resulted in the impaired GABAergic gating on neuronal excitability in amygdala, which was prevented by metyrapone pretreatment.
Answer: Our study suggests that enduring loss of tonic but not phasic GABAAR currents critically contributes to the prolonged amygdala disinhibition subsequent to chronic stress. We propose that the preferential loss of tonic inhibition may account for the development of stress-related neuropsychiatric diseases.

Output: Does chronic stress impair GABAergic control of amygdala through suppressing the tonic GABAA receptor currents?


Input: Consider Input: Context: An association between obesity and otitis media with effusion (OME) has been previously reported. The aim of this study was to evaluate the association between dietary intake and OME when adjusting obesity.', 'We analyzed the differences in dietary intake between children with/without OME who were 4 through 13 years of age using data from a large population-based survey - the Korea National Health and Nutrition Examination Survey - from 2008 through 2012. Data from 4359 participants were analyzed using simple and multiple logistic regression analyses with complex sampling.', 'The BMI category, the proportion of total calorie intake, protein intake, water intake, and Na intake (intake/recommendation), and the distribution of carbohydrate intake were not associated with OME. The distribution of fat intake was associated with OME (each 10% increase of fat calories/total calories: unadjusted odds ratio [OR]=1.331, 95% confidence interval [CI]=1.016-1.744, P=0.038; age- and sex-adjusted OR=1.359, 95% CI=1.028-1.797, P=0.031; adjusted for age, sex and other factors OR=1.392, 95% CI=1.054-1.839, P=0.020). Based on BMI subgroup analysis, the distribution of fat intake was associated with OME in the healthy weight group (each 10% increase of fat calories/total calories: unadjusted OR=1.393, 95% CI=1.017-1.909, P=0.039; adjusted OR=1.470, 95% CI=1.051-2.055, P=0.024) but not in the obese group.
Answer: A high-fat diet was associated with OME and may represent a confounding factor between obesity and OME.


Output: Is a high-fat diet associated with otitis media with effusion?
