user: Teacher: In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Context: Chronic rhinosinusitis (CRS) is a heterogeneous disease with an uncertain pathogenesis. Group 2 innate lymphoid cells (ILC2s) represent a recently discovered cell population which has been implicated in driving Th2 inflammation in CRS; however, their relationship with clinical disease characteristics has yet to be investigated. The aim of this study was to identify ILC2s in sinus mucosa in patients with CRS and controls and compare ILC2s across characteristics of disease. A cross-sectional study of patients with CRS undergoing endoscopic sinus surgery was conducted. Sinus mucosal biopsies were obtained during surgery and control tissue from patients undergoing pituitary tumour resection through transphenoidal approach. ILC2s were identified as CD45(+) Lin(-) CD127(+) CD4(-) CD8(-) CRTH2(CD294)(+) CD161(+) cells in single cell suspensions through flow cytometry. ILC2 frequencies, measured as a percentage of CD45(+) cells, were compared across CRS phenotype, endotype, inflammatory CRS subtype and other disease characteristics including blood eosinophils, serum IgE, asthma status and nasal symptom score. 35 patients (40% female, age 48 ± 17 years) including 13 with eosinophilic CRS (eCRS), 13 with non-eCRS and 9 controls were recruited. ILC2 frequencies were associated with the presence of nasal polyps (P = 0.002) as well as high tissue eosinophilia (P = 0.004) and eosinophil-dominant CRS (P = 0.001) (Mann-Whitney U). They were also associated with increased blood eosinophilia (P = 0.005). There were no significant associations found between ILC2s and serum total IgE and allergic disease. In the CRS with nasal polyps (CRSwNP) population, ILC2s were increased in patients with co-existing asthma (P = 0.03). ILC2s were also correlated with worsening nasal symptom score in CRS (P = 0.04).
Question: Are group 2 innate lymphoid cells ( ILC2s ) increased in chronic rhinosinusitis with nasal polyps or eosinophilia?
Solution: As ILC2s are elevated in patients with CRSwNP, they may drive nasal polyp formation in CRS. ILC2s are also linked with high tissue and blood eosinophilia and have a potential role in the activation and survival of eosinophils during the Th2 immune response. The association of innate lymphoid cells in CRS provides insights into its pathogenesis.
Reason: The output says that ILC2s are elevated in patients with CRSwNP and that they may drive nasal polyp formtion in CRS. The output also says that ILC2s are linked with blood eosinophilia and hence, it completely answers the question on the basis of the information in the context.

Now, solve this instance: Context: Gender has been shown to affect endothelial function of the forearm circulation in patients with type 2 diabetes, but data on the renal circulation are lacking. We hypothesized that renal vascular nitric oxide (NO) availability is higher, and oxidative stress lower, in female compared to male patients with type 2 diabetes.', 'In 41 male and 39 female patients with type 2 diabetes, renal plasma flow (RPF) was determined by constant infusion input clearance at baseline and following infusion of the NO synthase inhibitor N(G)-monomethyl-L-arginine (L-NMMA, 4.25 mg/kg) to assess basal renal vascular NO availability. After a subsequent infusion of L-arginine (100 mg/kg) to restore baseline conditions, vitamin C (45 mg/kg) was co-infused to determine levels of oxidative stress in the renal circulation.', 'Baseline renal haemodynamics were similar between genders. L-NMMA-induced renal vasoconstriction was more pronounced in females compared to males (-89 +/- 69 versus -60 +/- 52 ml/min/1.73 m(2), P = 0.03). After administration of L-arginine to restore baseline perfusion, the co-infusion of vitamin C led to a lesser increase of RPF in females than in males (+37 +/- 86 versus +60 +/- 52 ml/min/1.73 m(2), P = 0.05).\Question: Is gender related to alterations of renal endothelial function in type 2 diabetes?
Student:

assistant: Our data demonstrate that NO availability in the renal circulation is greater in female than in male patients with type 2 diabetes that is associated with reduced levels of oxidative stress in females. The role of this gender-related difference in renal endothelial function for the initiation and progression of diabetic nephropathy should be addressed in future studies.
