Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Q: Oxidative stress is implicated in the pathogenesis of atherosclerosis, and Nrf2 is the transcriptional factor central in cellular antioxidant responses. In the present study, we investigate the effect of a dihydrolipoic acid derivative lipoicmethylenedioxyphenol (LMDP) on the progression of atherosclerosis and test whether its effect on atherosclerosis is mediated by Nrf2.', 'Both magnetic resonance imaging (MRI) scanning and en face analysis reveal that 14 weeks of treatment with LMDP markedly reduced atherosclerotic burden in a rabbit balloon vascular injury model. Myograph analyses show decreased aortic contractile response to phenylephrine and increased aortic response to acetylcholine and insulin in LMDP-treated animals, suggesting that LMDP inhibits atherosclerosis through improving vascular function. A role of Nrf2 signaling in mediating the amelioration of vascular function by LMDP was supported by increased Nrf2 translocation into nuclear and increased expression of Nrf2 target genes. Furthermore, chemotaxis analysis with Boydem chamber shows that leukocytes isolated from LMDP-treated rabbits had reduced chemotaxis, and knock-down of Nrf2 significantly reduced the effect of LMDP on the chemotaxis of mouse macrophages.

Q: A prospective cohort study at our institution demonstrated a 48% mortality rate in warfarin anticoagulated trauma patients sustaining intracranial hemorrhage (ICH) compared with a 10% mortality rate in nonanticoagulated patients. Forty percent of patients demonstrated progression of their ICH, despite anticoagulation reversal, with a resultant 65% mortality rate. Seventy-one percent of these patients initially presented with a Glasgow Coma Scale (GCS) score > or = 14 and a 'minor' ICH. We postulated that early diagnosis of ICH and rapid anticoagulation reversal would reduce ICH progression rates and mortality.", 'All anticoagulated patients with known or suspected head trauma were entered into the Coumadin protocol. The protocol ensured immediate triage and physician evaluation, head computed tomography (CT) scan, and fresh frozen plasma administration in patients with documented ICH.', 'Eighty-two patients were entered into the protocol with ICH documented in 19 (23%). Sixteen of 19 patients (84%) presented with GCS > or = 14. Median international normalized ratio (INR) for treated patients with ICH was 2.7 versus 2.5 for patients without ICH (p = 0.546). Mean time to initiate warfarin reversal was 1.9 hours for protocol patients versus 4.3 hours for preprotocol patients (p < 0.001). Two of 19 (10%) protocol patients with ICH died. However, both patients presented >10 hours after injury with a severe ICH. This 10% mortality rate is significantly less than the 48% mortality rate seen previously (p < 0.001) and is now consistent with that observed in similarly injured patients not on anticoagulation.

Q: Induced aboveground plant defenses against pathogens can have negative effects on belowground microbial symbionts. While a considerable number of studies have utilized chemical elicitors to experimentally induce such defenses, there is surprisingly little evidence that actual aboveground pathogens affect root-associated microbes. We report here that an aboveground fungal pathogen of common bean (Phaseolus vulgaris) induces a defense response that inhibits both the belowground formation of root nodules elicited by rhizobia and the colonization with arbuscular mycorrhizal fungi (AMF).', 'Foliage of plants inoculated with either rhizobia or AMF was treated with both live Colletotrichum gloeosporioides-a generalist hemibiotrophic plant pathogen-and C. gloeosporioides fragments. Polyphenol oxidase (PPO), chitinase and β-1,3-glucanase activity in leaves and roots, as well as the number of rhizobia nodules and the extent of AMF colonization, were measured after pathogen treatments. Both the live pathogen and pathogen fragments significantly increased PPO, chitinase and β-1,3-glucanase activity in the leaves, but only PPO activity was increased in roots. The number of rhizobia nodules and the extent of AMF colonization was significantly reduced in treatment plants when compared to controls.
