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: Intrathecal adenosine is antinociceptive under conditions of central sensitization, but not in response to acute stimuli in normals. The reasons for this selective circumstance of action remain unclear, but some evidence links adenosine's antinociceptive effects to release of norepinephrine by terminals in the spinal cord. The purpose of this study was to test whether spinal adenosine induces norepinephrine release selectively in settings of hypersensitivity.", 'Rats randomly assigned to spinal nerve ligation, sham operation, or no operation were anesthetized. A microdialysis fiber was implanted in the spinal cord dorsal horn at the L5-L6 level and perfused with artificial cerebrospinal fluid. After washout and a baseline sample period, adenosine at various concentrations was infused through the fiber for 150 min, and samples were collected every 15 min.', "In ligated, but not in sham or normal animals, adenosine perfusion increased norepinephrine in spinal cord microdialysates in a concentration-dependent manner. The effects of adenosine plateaued after 75 min and remained stable until the end of the experiment. Intravenous injection of selective adenosine A1 and A2 receptor antagonists revealed that adenosine's effect on spinal norepinephrine release was A1 receptor mediated.\Question: Does intraspinal adenosine induce spinal cord norepinephrine release in spinal nerve-ligated rats but not in normal or sham controls?

Ex Output:
This is the first study to provide direct evidence that adenosine is able to release norepinephrine in spinal cord dorsal horns in living animals. However, this effect was only seen in animals after spinal nerve ligation. These data are consistent with behavioral studies demonstrating that adenosine's antinociceptive effects in rats after spinal nerve ligation is totally dependent on intact spinal noradrenergic terminals and can be blocked by spinal alpha 2-adrenergic receptor antagonists.


Ex Input:
Context: Sleep disorders are associated with cardiovascular complications and preterm delivery (PTD). Insufficient sleep results in metabolic alterations and increased inflammation, both known to contribute to placental abruption (abruption), a determinant of PTD. We examined associations of abruption with sleep duration and complaints of vital exhaustion.', 'The study included 164 abruption cases and 160 controls in a multicenter study in Peru. Data on habitual sleep duration and vital exhaustion during the first 6 months of pregnancy were elicited during interviews conducted following delivery. Women were categorized according to short, normal and long sleep duration (≤6, 7-8 and ≥9\u2009h); and frequency of feeling exhausted. Odds ratios (OR) and 95% confidence intervals (CI) were calculated.', 'Short and long sleep durations were associated with increased odds of abruption. The ORs of abruption in relation to short (≤6\u2009h) and long (≥9\u2009h) sleep duration were 2.0 (95% CI 1.1-3.7) and 2.1 (95% CI 1.1-4.1), compared with normal sleep duration (7-8\u2009h). Complaints of vital exhaustion were also associated with abruption (OR\u2009=\u20092.37; 95% CI 1.46-3.85), and were independent of sleep duration.\Question: Is maternal sleep duration and complaints of vital exhaustion during pregnancy associated with placental abruption?

Ex Output:
We extend the existing literature and support the thesis that maternal sleep habits and disorders should be assessed among pregnant women.


Ex Input:
Context: Type 1 diabetes mellitus (DM) is an autoimmune disorder with disturbed glucose/insulin metabolism, which has no medical treatment other than life-long insulin therapy, despite which 30% of subjects develop organ failure. Herein we have reported the use of human adipose-tissue-derived, insulin-making mesenchymal stem cells (h-AD-MSC) transfused with unfractionated cultured bone marrow (CBM) in 5 insulinopenic DM patients.', "Five (M:F, 2:3) insulinopenic DM patients of 0.6 to 10 years' duration, ages 14 to 28 years under treatment insulin (Human with 14-70 U/d) showed postprandial blood sugars between 156 to 470 mg%, glycosylated hemoglobin 6.8% to 9.9% and c-peptide levels of 0.02 to 0.2 ng/mL. They underwent intraportal administration of xenogeneic-free h-AD-MSC (mean dose = 1.5 mL; cell counts, 2.1 x 10(3)/muL). The CD45-/90+/73(+) cells (29.8/16.8%) showed c-peptide levels of 3.08 ng/mL, insulin level of 1578 micro IU/mL. The aliquot was supplemented with CBM (mean dose 94 mL with cell counts: 18.7 x 10(3)/microL) containing CD45-/34+ elements of 0.93%. The Institutional Review Board approved the study protocol and consent forms.", 'All patients were successfully infused CBM plus h-AD-MSC without any untoward effects and showed 30% to 50% decreased insulin requirements with 4- to 26-fold increased serum c-peptide levels, with a mean follow-up of 2.9 months.\Question: Do human adipose tissue-derived mesenchymal stem cells combined with hematopoietic stem cell transplantation synthesize insulin?

Ex Output:

This report describes safe and effective treatment of insulinopenic diabetics using insulin-producing h-AD-MSC plus CBM without xenogeneic materials.
