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.

Input: Consider Input: Context: Chronic pancreatitis (CP) and pancreatic cancer (PCa) are characterized by intrapancreatic neuropathic alterations, including increased neural density and hypertrophy, pancreatic neuritis and neural invasion (NI) by cancer cells in PCa. The aim of this study was to identify the influence of these neuropathic changes on the quality of pancreatic innervation, intrapancreatic glia, and visceral pain.', 'Pancreatic nerve fiber qualities were characterized by immunohistochemical visualization of various markers, including those for sympathetic (tyrosine hydroxylase, TH) and cholinergic innervation (choline acetyltransferase, ChAT), as well as the glial transcription factor, Sox10, and the neuroepithelial progenitor cell marker, Nestin, in normal pancreas (NP, n=16), CP (n=20), and PCa (n=20) patients. The neural immunoreactivity scores of these markers were correlated with the severity of intrapancreatic neuropathic changes and with abdominal pain sensation of patients.', 'Pancreatic sympathetic innervation was significantly reduced in CP and PCa, whereas parasympathetic innervation did not show major changes. Nestin neuro-immunoreactivity was stronger, and Sox10-immunoreactivity was weaker in CP and PCa than in NP. Pancreatic sympathetic and cholinergic innervation was noticeably decreased in patients with severe pancreatic neuritis, NI by cancer cells, or abdominal pain. Moreover, the neural immunoreactivity for Sox10 and Nestin also varied with intrapancreatic neuropathic alterations and abdominal pain.\Question: Does pancreatic neuropathy result in '' neural remodeling '' and altered pancreatic innervation in chronic pancreatitis and pancreatic cancer?

Output: The quality of intrapancreatic nerve fibers and the activation state of intrapancreatic glia in CP and PCa are strikingly different from those in normal pancreas. This novel phenomenon of "neural remodeling" shows how pancreatic neuropathic pain and "visceral neuropathy" are associated with altered pancreatic innervation in CP and PCa.

Input: Consider Input: Context: For patients with cystic fibrosis (CF) Pseudomonas aeruginosa infection is a major contributor to progressive lung disease. While colonizing strains are thought to be primarily environmental, which environments are important in lung colonization is unclear.', 'We took 11,674 samples from a broad range of sites over 3-8 visits to homes with (7) and without (8) CF patients.', 'Twenty-eight percent of sampled drains yielded P. aeruginosa at least once, and a general mixed linear model estimated that 6.3% of samples from drains yield P. aeruginosa. This is more than eight times the estimated recovery from any other type of household environment.\Question: Is pseudomonas aeruginosa in CF and non-CF homes found predominantly in drains?

Output: These findings implicate drains as important potential sources of P. aeruginosa infection. They suggest that maximizing P. aeruginosa control efforts for drains would reduce exposure with minimal extra burden to CF patients and families.

Input: Consider Input: Context: To evaluate the effect of the fibrin sealant, Evicel, on the neuroregulatory control of penile erections in an experimental rat model.', 'Two groups of rats were used: sham-operated rats with exposure of the bilateral cavernous nerves (CNs) and application of saline vehicle (500 microL), and rats treated with direct application of Evicel (500 microL) bilaterally to the CNs. At 14 and 45 days after application of Evicel to the CNs, the CNs were stimulated to measure the in vivo erectile responses. Additionally, we evaluated the neuronal nitric oxide synthase immunoreactivity in the dorsal CNs of the penis and changes in the smooth muscle and collagen deposition in the penis using a trichrome stain.', 'Evicel application to the CNs did not have any detrimental effect on the neurogenic erectile responses in vivo at 14 or 45 days after application. The neuronal nitric oxide synthase expression in the dorsal CNs of the penis was unchanged after Evicel application at all points studied, and we saw no change in the histomorphometric analysis findings of smooth muscle and collagen deposition in the penis.\Question: Does application of Evicel to cavernous nerves of the rat influence erectile function in vivo?
Output: These data suggest that the hemostatic agent, Evicel, is safe in an experimental rat model of erection physiology, with no detrimental effects on neuroregulatory control of erection.
