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.

Ex Input:
Context: "Virtual fracture clinics" have been reported as a safe and effective alternative to the traditional fracture clinic. Robust protocols are used to identify cases that do not require further review, with the remainder triaged to the most appropriate subspecialist at the optimum time for review. The objective of this study was to perform a "top-down" analysis of the cost effectiveness of this virtual fracture clinic pathway.', 'National Health Service financial returns relating to our institution were examined for the time period 2009 to 2014 which spanned the service redesign.', 'The total staffing costs rose by 4% over the time period (from 1 744 933 to 1 811 301) compared with a national increase of 16%. The total outpatient department rate of attendance fell by 15% compared with a national fall of 5%. Had our local costs increased in line with the national average, an excess expenditure of 212 705 would have been required for staffing costs.\Question: Does fracture clinic redesign reduce the cost of outpatient orthopaedic trauma care?

Ex Output:
The virtual fracture clinic system was associated with less overall use of staff resources in comparison to national cost data. Adoption of this system nationally may have the potential to achieve significant cost savings.Cite this article: P. J. Jenkins.

Context: Bronchopulmonary carcinoid tumors can be divided into typical and atypical carcinoids according to their histologic and clinical features. Atypical carcinoids tend to have less predictable biologic behavior and are associated with a worse prognosis than typical carcinoids. The authors examined apoptosis and the expression of apoptosis regulating proteins Bcl-2, Bax, Bak, and Mcl-1 in 21 typical and 10 atypical bronchopulmonary carcinoid tumors. To find features distinguishing the growth of these types of tumors, the expression of p53 protein and the proliferation marker Ki-67 were also investigated. Finally, the parameters were compared with clinical follow-up data.', "Thirty-one bronchopulmonary carcinoid tumors were examined by using in situ 3'-end labeling of DNA (TUNEL) for apoptosis and immunohistochemical staining methods for Bcl-2, Bax, Bak, Mcl-1, p53, and Ki-67 in formalin fixed, paraffin embedded tissue specimens.", 'The apoptotic indices (AIs) were low in general (mean 0.18%), but higher AIs (> 0.5%) were observed significantly more often in atypical than in typical carcinoids (P < 0.008) in association with shortened survival (P < 0. 008). No relation between apoptosis and Bcl-2, Bax, Bak, or Mcl-1 expression was found. Expression of p53 protein was detected in only three atypical carcinoids, which also had significantly higher AIs than p53 negative tumors (P < 0.03). Proliferation rates measured by Ki-67 index were unusually low; the highest proliferation rates were observed in atypical carcinoids. There was a positive correlation between AI and Ki-67 indices (P < 0.01).\Question: Do atypical bronchopulmonary carcinoids show a tendency toward increased apoptotic and proliferative activity?

Ex Output:
This study suggests that the extent of apoptosis in bronchopulmonary carcinoid tumors is low. This, together with a low proliferation rate and an apparent absence of p53 mutation, enables a benign growth pattern. Some atypical carcinoids with enhanced apoptosis are associated with shortened survival, clearly deviating from typical carcinoids.

Context: Although N(2)O has been widely used as an anaesthetic adjuvant its effect on electroencephalographic (EEG) activity is poorly understood because it is usually studied in the presence of additional anaesthetics, including inhaled anaesthetics. We examined the EEG effects of N(2)O in rats using a hyperbaric chamber that permitted N(2)O to be the sole anaesthetic.', 'Rats (n=10) were anaesthetized with isoflurane and EEG activity was recorded from skull screws. The rats were placed into a hyperbaric chamber and mechanically ventilated. Isoflurane was eliminated while the chamber was pressurized with N(2)O. The minimum alveolar concentration (MAC) was determined in five rats by adjusting the chamber pressure and N(2)O concentration, and applying a tetanic noxious stimulus to the tail via an electrical pass-through. EEG responses to noxious stimulation (20 electrical pulses at 40 V applied to the tail at 0.1, 1 and 3 Hz, and 50 Hz tetanic stimulation at 60 mA applied for 30 s) were determined at 1.5 and 2 atm N(2)O.', 'The N(2)O MAC was 1.7+/-0.1 atm. No consistent EEG activation occurred during electrical stimulation at either partial pressure of N(2)O, although spontaneous EEG activation often occurred. Blood pressure increased after the 3 and 50 Hz stimuli. Four other rats anaesthetized with isoflurane had EEG activation with the 3 and 50 Hz stimuli.\Question: Does nitrous oxide depress electroencephalographic responses to repetitive noxious stimulation in the rat?

Ex Output:
These data indicate that N(2)O at peri-MAC partial pressures prevents EEG activation resulting from noxious electrical stimulation. Unlike the situation with isoflurane, stimulus-evoked EEG activation did not occur at peri-MAC anaesthetic concentrations, suggesting that N(2)O potently blocked ascending nociceptive transmission.
