Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

Input: Consider Input: To describe the epidemiology of acute hand injuries and hand infections and to describe the factors associated with the transfer of these patients to a level 1 trauma center. In addition, we sought to understand management before transfer.', 'Retrospective review of patients with hand trauma or hand infection transferred to our level 1 trauma center from May 2009 to August 2011. We also identified hospitals with emergency departments (EDs) in our region and surveyed ED providers in these hospitals with regard to acute hand care.', 'A level 1 trauma center in the United States.', 'Four hundred sixty consecutive transfers for acute hand care.', 'The average patient age was 38. Most were male (84%), uninsured (51%), and from another county (59%). The average distance of transfer was 51 miles, and 80% were transferred by ground ambulance. The most common reasons for transfer were amputations (24%), infections (21%), lacerations (17%), and fractures/dislocations (16%). Of the 345 hospitals with an ED surveyed, 71% never had hand surgery coverage.

Output: Do lack of Acute Hand Care in the Southwest United States?


Input: Consider Input: Regular physical activity is an effective non-pharmacological therapy for prevention and control of hypertension. However, the underlying mechanisms are not fully understood. Accumulating evidence shows that the elevated vascular tone in hypertension is a consequence of the 'ion channel remodelling' that occurs during sustained high BP. The present study investigated the effects of aerobic exercise on the electrical remodelling of L-type Ca(2+) (Cav 1.2) and large-conductance Ca(2+) -activated K(+) (KCa 1.1) channels in mesenteric arteries (MAs) from spontaneously hypertensive rats (SHRs).", 'SHRs and normotensive (Wistar-Kyoto) rats were subjected to aerobic training or kept sedentary, and vascular mechanical and functional properties were evaluated.', 'Exercise did not affect the heart weight, but reduced the heart rate and body weight in SHR. In mesenteric arterial myocytes, exercise normalized the increased Cav 1.2 and KCa 1.1 current density in SHRs. Exercise also ameliorated the increased open probability and mean open time of the single KCa 1.1 channel in hypertension. The isometric contraction study revealed that both nifedipine (Cav 1.2 channel blocker) and NS11021 (KCa 1.1 channel activator) induced concentration-dependent vasorelaxation in MAs precontracted with noradrenaline. Exercise normalized the increased sensitivity of tissues to nifedipine and NS11021 in SHR. Furthermore, protein expression of the Cav 1.2 α1C -subunit together with the KCa 1.1 α- and β1-subunit was significantly increased in SHRs; and exercise ameliorated these molecular alterations in hypertension.

Output: Does chronic exercise normalize changes in Cav 1.2 and KCa 1.1 channels in mesenteric arteries from spontaneously hypertensive rats?


Input: Consider Input: To examine antigen (Ag)-specific CTL response during anterior chamber associated immune deviation (ACAID).', "OVA or OVA257-264 peptide was injected into the anterior chamber (AC) of C57BL/6 mice. There were 16 mice in each ACAID group induced with OVA or OVA257-264 peptide. The mice were primed by SC injection with OVA or OVA 257-264 peptide in complete Freund's adjuvant (CFA) on day 7. Ag-specific CD8+ T cells in spleens were analyzed on day 14 using Pentamer H-2K(b)-SIINFEKL(OVA257-264 peptide). IFN-gamma ELISPOT and intracellular granzyme B staining were used to characterize the CTL response. Twelve mice in each group immunized with OVA or OVA257-264 peptide in CFA served as positive controls. Twelve normal mice served as negative controls and 12 receiving injection of CFA as CFA controls for studying the influence of CFA on the Ag-specific CTL response.", 'The results showed that anterior chamber inoculation of OVA or OVA257-264 peptide could induce ACAID as evidenced by an impaired DTH response. The frequency of Ag-specific CD8+ T cells in ACAID mice was not different from that in mice challenged with Ags in CFA only (positive controls). IFN-gamma production by these cells in ACAID mice was not different compared to positive controls. However, Ag-specific CD8+ T cells in ACAID mice failed to secrete granzyme B. Mice challenged only with OVA peptide and CFA also showed a granzyme B negative CD8+ T cell response. Ag-specific CTL response induced by CFA alone was similar with the negative control.


Output: Do oVA-specific CD8+ T cells do not express granzyme B during anterior chamber associated immune deviation?
