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: Neonatal therapy-resistant septic shock is a common problem in middle and low-income countries. We investigated whether newborn infants with infection and therapy-resistant hypotension showed evidence of abnormal levels of cortisol or cortisol precursors.', 'A total of 60 term or near term neonates with evidence of infection were enrolled after informed consent. Of these, 30 had an infection and refractory shock and 30 had an infection without shock. There were no detectable differences between the groups in the length of gestation, birth weight or gender distribution. Serum was obtained during days four and 14 after birth. Cortisol and cortisol precursor concentrations were analysed using liquid chromatography-tandem mass spectrometry.', 'The cortisol concentrations were low considering the expected responses to stress and they did not differ between the groups. The infants with infection and shock had higher serum dehydroepiandrosterone (DHEA) levels than those without shock (319.0 ± 110.3 μg/dL, versus 22.3 ± 18.3 μg/dL; p < 0.0001) and they also had higher 17-hydroxy-pregnenolone, pregnenolone and progesterone concentrations. There were no detectable differences in the levels of 17-hydroxy-progesterone, 11-deoxy-cortisol, cortisol or cortisone.

Q: The hormone melatonin regulates the sleep and this pineal hormone is synthesized in the organism from the amino acid tryptophan. It is known that breast-fed babies have better sleep patterns and a better entrained sleep/wake cycle than bottle-fed babies (adapted formula).', "To compare the circadian rhythm of 6-sulfatoxymelatonin (aMT6s)--the metabolite of melatonin excreted in the urine--in urine of bottle-fed and breast-fed children, and relate it to the circadian rhythm of tryptophan in breast milk, also evaluating the possible effects on the baby's night-time rest.", '16 infants of 12 weeks of age were studied, divided into two groups depending on their exclusively natural or artificial feeding. The circadian rhythm of 6-sulfatoxymelatonin in urine was measured for the two groups of infants and for the breast-feeding mothers. In the breast milk, the circadian rhythm of the amino acid tryptophan was measured. The rest of the infants was tested by wrist actimeters for a week and the sleep parameters of the infants were measured and evaluated.', 'The tryptophan in the breast milk presented a circadian rhythm with acrophase at around 03:00. This affected the 6-sulfatoxymelatonin circadian rhythm with acrophase at 06:00 in the breast-fed infants, and also promoted nocturnal sleep. Assumed sleep, actual sleep, and sleep efficiency were significantly increased in the breast fed infants with respect the formula fed infants.

Q: Impaired resolution of acute inflammation results in development of chronic inflammatory disorders such as atherosclerosis, asthma and arthritis. Clearance of apoptotic neutrophils by M2 macrophages, the process termed efferocytosis, is critical for complete resolution of inflammation as it prevents secondary necrosis caused by disgorgement of toxic contents from apoptotic cells in the inflamed site. In the present study, we investigated the effect of docosahexaenoic acid (DHA) on efferocytosis.', 'To determine the effect of DHA on efferocytosis, murine macrophage-like RAW264.7 cells were co-incubated with apoptotic Jurkat T cells, and efferocytosis was assessed by flow cytometry. The expression and production of M1 and M2 markers were determined by RT-PCR, ELISA and flow cytometry. To demonstrate the involvement of peroxisome proliferator-activated receptor γ (PPARγ) in DHA-mediated effects, siRNA against PPARγ was utilized. The expression of PPARγ was examined by semiquantitative reverse-transcription polymerase chain reaction (RT-PCR), Western blot analysis and immunocytochemistry. The PPARγ activation was measured by the electrophilic gel shift assay.', 'DHA enhanced the efferocytic ability of RAW264.7 cells, and induced their M2 polarization. Notably, knockdown of PPARγ abolished the stimulatory effect of DHA on M2 polarization as well as efferocytosis. Furthermore, lipopolysaccharide-induced production of pro-inflammatory cytokines was significantly inhibited by DHA, suggesting that DHA alters the macrophage phenotype in favor of M2 while it suppresses M1 polarization.
