TASK DEFINITION: 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.
PROBLEM: 1,8-Cineole, the main monoterpene in many essential oils, has been used as an ingredient in flavourings and medicine. 1,8-Cineole has been shown to possess pharmacological properties, including anti-oxidative, anti-inflammatory and anti-nociceptive actions. However, to date, no studies have examined the potential of 1,8-cineole to protect against cerebral ischaemic injury.', 'In this study, we investigated the neuroprotective effects of 1,8-cineole against cortical neuronal/glial cell injury caused by oxygen-glucose deprivation/reoxygenation (OGD/R) in an in-vitro model of ischaemia.', '1,8-Cineole significantly attenuated OGD/R-induced cortical cell injury, as well as reduced n-methyl-d-aspartate (NMDA)-induced cell injury. However, it did not inhibit NMDA-induced cytosolic calcium overload. Nevertheless, 1,8-cineole significantly reduced the OGD/R- and NMDA-induced overproduction of reactive oxygen species (ROS). These results indicate that 1,8-cineole exerts neuroprotection through its anti-oxidative rather than its anti-excitotoxic, properties. The decrease in OGD/R-induced intracellular superoxide in 1,8-cineole-treated cortical cells was associated with the upregulation of superoxide dismutase activity. Moreover, 1,8-cineole showed direct ROS scavenging activity in an assay of oxygen radical absorbance capacity.

PROBLEM: The authors set out to analyze if a simple comprehensive geriatric assessment (CGA) could objectively identify elderly patients with diffuse large cell lymphoma (DLCL) who can be effectively treated with anthracycline-containing immunochemotherapy.', 'CGA was performed in 84 consecutive patients with DLCL aged >65 years and diagnosed at a single institution. Treatment with curative versus palliative intent was chosen according to clinical judgment. Cyclophosphamide, hydroxydaunomycin, Oncovin (vincristine), and prednisone (CHOP) or CHOP-like regimens were given to 62 (74%) patients. The outcome of patients was analyzed according to both the treatment received and the results of CGA.', 'According to CGA, 42 (50%) patients were classified as "fit." They were younger (P < .0001) and had less frequent systemic symptoms (P = .03). These patients received curative treatment by clinical judgment. Their response rate (92.5% vs 48.8%; P < .0001) and median survival (not reached vs 8 months; P < .0001) were significantly better than those of 42 patients considered "unfit" by CGA. Among unfit patients, 20 had actually received curative and 22 palliative therapy. These subgroups did not differ in any geriatric or lymphoma-related characteristic. Their outcome was similar irrespectively of the type of treatment received (median survival, 8 vs 7 months; P = nonsignificant). Lymphoma rather than toxicity was the main cause of failure/death also among unfit patients treated aggressively.

PROBLEM: Increased progesterone level during follicular phase seemed to be associated with decreased pregnancy rate.', 'A prospective cohort study, 1.1.2012 - 31.8.13. The Progesterone (P) and Progesterone/Estrogen (P/E2) level on ovulation induction day were compared between the protocols and the different gonadotropins used. Roc analysis was calculated to determine the cutoff of P/E2 to predict delivery rates. P/E2 ratio was calculated as PX1000/e2 level.', 'One hundred thirty-nine patients were enrolled to the study. No difference in the P level at hCG stimulation day between different protocols, however, E2 and P/E2 ratio were significantly lower in the long protocol compare with antagonist protocol 1757.7923.2 vs. 1342.91223; P=0.003 and 0.480.31 vs. 0.830.87; P=0.038). The endometrium was significantly thicker in the long group compare with short and antagonist. Significantly more top-quality embryos (TOP) were achieved in the antagonist group. Comparable results between the types of gonadotropins used in regards with cycle characteristics and pregnancy and delivery rates. The P/E2 ratio which can predict live birth rate was found to be 0.45, AUC=0.632, p=0.02 and 95% CI 0.525-0.738 and a significantly higher pregnancy and delivery rates at a P/E2 bellow 0.45.
