Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

[EX Q]: The relationship of bipolar disorder (BD) and altered thyroid function is increasingly recognized. Recently, a behavioral phenotype of co-occurring deviance on the Anxious/Depressed (A/D), Attention Problems (AP), and Aggressive Behavior (AB) syndrome scales has been identified as the Child Behavior Checklist Dysregulation Profile (CBCL-DP), which itself has been linked to BD. This study tested for differences in thyroid function within a sample of n=114 psychiatric children and adolescents with and without the CBCL-DP.', 'A CBCL-DP score was generated based on the composite of the crucial CBCL syndrome scales (A/D, AP, AB). Participants with a CBCL-DP score >or=2.5 SDs above average constituted the CBCL-DP subgroup (n=53). Those with CBCL-DP scores of 1 SD or less above average percentile were regarded as controls (n=61). Groups were compared regarding serum levels of TSH, fT3 and fT4.', 'In participants showing the CBCL-DP, basal serum TSH was elevated compared to controls. More CBCL-DP subjects than controls showed subclinical hypothyroidism. No differences were observed for serum fT3 and fT4 levels.

[EX Q]: To investigate the inhibition of amyloid beta-protein 42 (Abeta42) production in M146L cells by gamma-schisandrin.', 'M146L cells which can produce considerable Abeta42 in vitro were treated with gamma-schisandrin (1.67, 5.00 and 15.00 microg x mL(-1)), beta-secretase inhibitor (S4562, 100.00 microg x mL(-1)) and gamma-secretase inhibitor (S2188, 13.68 microg x mL(-1)), separately. Cell counting kit-8 (CCK-8) was used to assess cell viability. Enzyme-linked immunosorbent assay (ELISA) was carried out to determine the amount of Abeta42. Western blotting was used to examine C99, an intermediary product of APP cleaved by beta-secretase. beta-Secretase and gamma-secretase activities were assayed by commercial kits.', 'The CCK-8 assay indicated that different concentrations of gamma-schisandrin had no neurotoxicity on the cultured M146L. And the ELISA test showed that the amount of Abeta42 secreted by M146L cells treated with gamma-schisandrin (5.00 and 15.00 microg x mL(-1)) decreased obviously as compared with solvent control. The results of Western blotting test indicated that there was no change of C99 contents and beta-secretase activity in gamma-schisandrin treated cells, while gamma-secretase activity decreased obviously.

[EX Q]: Subarachnoid hemorrhage (SAH) is a devastating neurological injury associated with significant morbidity and mortality. We postulated that lipopolysaccharide (LPS) preconditioning induces neuroprotection against early brain injury (EBI) after experimental SAH.', "72 male Sprague-Dawley rats (250 to 300 g) were used. SAH was produced by injecting autologous arterial blood into the pre-chiasmatic cistern. Rats were given an intraperitoneal injection of LPS 24 hours prior SAH. Matrix metalloproteinase 9 (MMP-9) protein expression was measured by western blot; apoptosis in the cerebral cortex were studied by terminal deoxynucleotidyl transferasemediated deoxyuridine triphosphate-biotin nick-end labeling (TUNEL) and 4'6-diamidino-2-phenylindole dihydrochloride (DAPI) staining at 24 h after SAH. Brain water content was also examined.", 'MMP-9 expression was increased after SAH and decreased by LPS preconditioning at 24 h after SAH. The number of neuronal death in cortex was increased after SAH and decreased by LPS preconditioning. In addition, brain water content was attenuated by LPS preconditioning.
