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.

[Q]: Context: P53 is a key protein which controls cell cycle arrest and apoptosis in response to DNA damage. Auto-antibodies against p53 have been detected in some cancer patients and also in patients with autoimmune diseases. In these patients, the main cause of anti-p53 antibody occurrence was considered to be increased intracellular p53 protein in cancer cells and autoreactive lymphocytes, respectively. Intracellular p53 also increases with cardiomyocyte apoptosis during heart failure and autoreactive lymphocytes play a role in the course of idiopathic dilated cardiomyopathy (IDC) and ischemic cardiomyopathy (ICM). Based on these observations, we hypothesized that anti-p53 antibody response may also occur in patients with heart failure due to ICM and IDC.', 'The aim of this study was to evaluate anti-p53 antibodies in the serum of patients with heart failure due to IDC and ICM.', '70 eligible patients with heart failure and severe left ventricular systolic dysfunction (mean fractional shortening 12.03 +/- 3.93%) were included in the study. The aetiology of heart failure was IDC in 26 patients and ICM in 44 patients, according to the angiographic and echocardiographic findings.', 'Anti-p53 antibodies were not detected in any of the patients.\Question: Do serum anti-p53 antibodies occur in patients with heart failure due to idiopathic dilated and ischemic cardiomyopathies?
[A]: Anti-p53 antibodies do not occur in patients with heart failure due to IDC and ICM, possible explanations are discussed in the text.


[Q]: Context: In developmental research, infants are commonly assumed to be early stakeholders in interactions with their caregivers. The tools that infants can use to interact with others vary from visual contact to smiling or vocalizing, and also include motor activity. However, surprisingly few studies have explored how the nature and context of social interactions affect infants' engagement in motor activity.", "We investigated the kinematic properties of foot and face movements produced by 11 infants aged between 5 and 9 months during six contrasting dyadic episodes (i.e. passive presence of a stranger or the infant's mother, weak or intense interaction with the stranger/mother as she sings a nursery play song).", "The infants' face and foot motor activity was significantly reduced during the interactive episodes, compared with the episodes without any interaction, in both the mother and stranger conditions. Furthermore, the level of their motor activity was significantly lower in the stranger condition than in the mother one for some parameters.\Question: Is social interaction associated with changes in infants ' motor activity?
[A]: These results are in line with those reported by previous studies and confirm the relevance of using motor activity to delineate the early forms of interactive episodes in infants.


[Q]: Context: Paraplegia can result from operations requiring transient occlusion of the thoracic aorta. A rat model of paraplegia with the characteristics of delayed paraplegia and transient ischemic dysfunction was developed to determine whether ischemic preconditioning (IPC) improved neurologic outcome.', 'Rats underwent balloon occlusion of the upper descending thoracic aorta. One group (2 minute IPC, n = 19) underwent 2 minutes of IPC and a second group (5 minute IPC, n = 19) had 5 minutes of IPC 48 hours before 10 minutes of occlusion. The control group (n = 31) had no IPC prior to 10 minutes of occlusion.', 'Paraplegia occurred in 68% of the control animals (21 of 31 paraplegic: 6 delayed and 15 immediate paraplegia). Both the 2-minute IPC and 5-minute IPC groups had a decreased incidence of paraplegia when compared to controls (32%, p = 0.011 and 26%, p = 0.009, respectively).\Question: Does ischemic preconditioning protect against paraplegia after transient aortic occlusion in the rat?
[A]:
A rat model of spinal cord ischemia demonstrating both delayed paraplegia and transient ischemic dysfunction was characterized. Both 2-minute and 5-minute periods of IPC were found to protect against paraplegia.
