Given a passage, construct a question on the basis of the information present in the passage. 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.

Q: Crowdsourcing dietary ratings for food photographs, which uses the input of several users to provide feedback, has potential to assist with dietary self-monitoring.', "This study assessed how closely crowdsourced ratings of foods and beverages contained in 450 pictures from the Eatery mobile app as rated by peer users (fellow Eatery app users) (n = 5006 peers, mean 18.4 peer ratings/photo) using a simple 'healthiness' scale were related to the ratings of the same pictures by trained observers (raters). In addition, the foods and beverages present in each picture were categorized and the impact on the peer rating scale by food/beverage category was examined. Raters were trained to provide a 'healthiness' score using criteria from the 2010 US Dietary Guidelines.", "The average of all three raters' scores was highly correlated with the peer healthiness score for all photos (r = 0.88, p<0.001). Using a multivariate linear model (R(2) = 0.73) to examine the association of peer healthiness scores with foods and beverages present in photos, peer ratings were in the hypothesized direction for both foods/beverages to increase and ones to limit. Photos with fruit, vegetables, whole grains, and legumes, nuts, and seeds (borderline at p = 0.06) were all associated with higher peer healthiness scores, and processed foods (borderline at p = 0.06), food from fast food restaurants, refined grains, red meat, cheese, savory snacks, sweets/desserts, and sugar-sweetened beverages were associated with lower peer healthiness scores.

A: Are the use of crowdsourcing for dietary self-monitoring : crowdsourced ratings of food pictures comparable to ratings by trained observers?

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.

A: Does [ Gamma-Schisandrin inhibit production of amyloid beta-protein 42 in M146L cells ]?

Q: To determine whether follicle curetting at the time of oocyte retrieval increases oocyte yield.', 'Retrospective review of all patients who underwent oocyte retrieval from July 1, 2003 to June 30, 2005.', 'Number of oocytes retrieved.', 'retrieval time, number of cryopreserved embryos, pregnancy rates, and incidence of ovarian hyperstimulation syndrome.', 'There were no differences in patient demographics, antral follicle count, cycle stimulation characteristics, fertilization rates, embryo quantity or quality, embryo cryopreservation rates, clinical pregnancy rates, live birth rates, or ovarian hyperstimulation syndrome between the groups. Retrievals that utilized curetting took three minutes longer. Follicle curetting significantly increased the number of oocytes retrieved, 13.9 +/- 0.6 compared to 11.4 +/- 0.6 oocytes without curetting (P = 0.003). The quantity of mature oocytes was also increased with curetting (10.3 +/- 0.5 versus 8.4 +/- 0.5, P = 0.006).

A:
Does follicle curetting at the time of oocyte retrieval increase the oocyte yield?
