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: The present study was designed to investigate whether H2S can protect testicular germ cells against heat exposure induced injury and the underlying mechanisms.', 'It was found that all three H2S generating enzymes, cystathionine β-synthase (CBS), cystathionine γ-lysase (CSE), and 3-mercaptopyruvate sulfurtransferase (3 MST), were expressed in mouse testicular tissue. Three episodes of heat exposure (42 °C, 30 min/day, 3 days) significantly decreased endogenous H2S production and down-regulated the expression of CBS and CSE in testes. In primary cultured testicular germ cells, exogenous application of NaHS (an H2S donor) attenuated heat stress (42 °C, 30 min) induced cell death and apoptosis. This was mediated by the inhibitory effects of H2S on cytochrome C release and the ratio of the Bax/Bcl-2. NaHS also improved mitochondrial function by decreasing oxygen consumption and increasing ATP production. NaHS treatment also stimulated SOD activity and reduced ROS production.\Question: Does hydrogen sulfide protect testicular germ cells against heat-induced injury?

Output: Our results revealed both physiological and pharmacological roles of H2S in testicular germ cells. Exogenous application of H2S may protect germ cells by preservation of mitochondrial function and stimulation of anti-oxidant activity.


Input: Consider Input: Context: The aim of this study was to assess the effect of the implementation of evidence-based guidelines and subsequent feedback to surgeons in the management of acute pancreatitis.', 'An evidence-based Pancreatitis Proforma was developed. Data were prospectively recorded (01/06/2005-30/09/2007). Audit feedback (AFB) was performed at 9 months. A final analysis was performed comparing outcomes pre- and post-audit feedback.', '372 patients were included. Median age (range) was 57 (12-96) years. 168 (45.2%) patients were admitted pre-AFB. Post-AFB, there was a significant increase in the number of patients whose diagnosis was made within 48 hours (135/168 (80.4%) vs 189/204 (92.6%), p<0.001) and who underwent definitive treatment for mild biliary pancreatitis (33/61 (54.1%) vs 56/70 (80.0%), p=0.002). Post-AFB there was also a significant reduction in the number of computed tomography (CT) scans performed for patients with mild acute pancreatitis (23/85 (27.1%) vs 13/99 (13.1%), p=0.018). Mortality (9/168 (5.4%) vs 3/204 (1.4%), p=0.040) also decreased. On multivariate analysis, AFB was an independent factor for change in the use of CT scans (p=0.015) and management of patients with mild biliary pancreatitis (p=0.039).\Question: Is closing the audit loop necessary to achieve compliance with evidence-based guidelines in the management of acute pancreatitis?

Output: For evidence-based guidelines to be effective, feedback to surgeons is necessary.


Input: Consider Input: Context: Many insect cytochrome P450s (CYPs) play critical roles in detoxification of insecticides. The CYP6 family is unique to the class Insecta, and its biochemical function has essentially been associated with the metabolism of xenobiotics. In this study, we sequenced and characterised the full-length cDNAs of five CYP genes from Locusta migratoria, a highly destructive agricultural pest worldwide.', 'The five genes were predominantly expressed in brain, guts, fat bodies or Malpighian tubules. CYP6FE1, CYP6FF1 and CYP6FG1 were expressed at higher levels in fourth-instar nymphs than in other developmental stages. CYPFD2 is specifically expressed in adults, whereas CYP6FD1, CYP6FD2 and CYP6FE1 showed significantly lower expression in eggs than in other developmental stages. Deltamethrin suppressed CYP6FD1 expression in third-instar nymphs and upregulated the expression level of CYP6FD2, CYP6FF1 and CYP6FG1 at the dose of LD\Question: Does rNA interference of cytochrome P450 CYP6F subfamily genes affect susceptibility to different insecticides in Locusta migratoria?


Output: Three of the four CYP6F subfamily genes in L. migratoria were associated with the detoxification of deltamethrin or carbaryl. The role of CYPs in insecticide detoxification appears to be both gene and insecticide specific. © 2016 Society of Chemical Industry.
