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.

To test the effect of substituting a modified-fat cheese product into the diets of hypercholesterolemic adults.', 'A 4-month, randomized, double-blind, crossover substitution trial.', 'General community outpatient study.', 'Twenty-six healthy adult volunteers (17 men, 9 women) with moderate hypercholesterolemia (total cholesterol > 5.69 mmol/L but < 7.24 mmol/L).', "Daily substitution of 100 g of cheese, either partial skim-milk mozzarella or modified-fat (vegetable oil) mozzarella cheese product, into participants' normal diets. Participants consumed an assigned cheese for 2 months, at which time they crossed over to consume the other study cheese.", 'Plasma lipid and apolipoprotein levels were measured at baseline and at 2 and 4 months after initiation of the study. Compliance was assessed by body weight and by biweekly dietary records and interviews.', 'No differences in weight or in the amount or type of calories consumed were found during the study. No statistically significant changes in lipid values resulted from consumption of mozzarella cheese. Modified-fat cheese substitution resulted in a decreased low-density lipoprotein cholesterol level when compared with levels at both baseline (-0.28 mmol/L; 95% Cl, -0.14 to -0.42 mmol/L) and during consumption of the skim-milk mozzarella cheese (-0.38 mmol/L; 95% Cl, -0.2 to -0.70 mmol/L). Findings for total cholesterol were similar. High-density lipoprotein cholesterol, plasma triglyceride, and apolipoprotein A-l and B-100 levels were unaltered. Both sexes responded similarly.
Does a linoleate-enriched cheese product reduce low-density lipoprotein in moderately hypercholesterolemic adults?

Since manganese (Mn) is capable of stimulating the hypothalamic-pituitary unit and advancing female puberty, we assessed the possibility that this element might overcome some of the detrimental effects of prepubertal alcohol (ALC) exposure on the hypothalamic control of pituitary function.', 'Rats received either saline or Mn (10mg/kg) daily by gastric gavage from day 12 to day 31. After weaning, all rats were provided Lab Chow diet ad libitum until day 27 when they began receiving either the Bio Serv control or ALC diet regime. On day 31, the medial basal hypothalamus (MBH) was collected to assess luteinizing hormone-releasing hormone (LHRH) and cyclooxygenase 2 (COX2) protein levels. Release of prostaglandin-E2 (PGE2), LHRH and serum luteinizing hormone (LH) were also assessed. Other animals were not terminated on day 31, but remained in study to assess timing of puberty.', 'Short-term ALC exposure caused elevated hypothalamic LHRH content, suggesting an inhibition in peptide release, resulting in a decrease in LH. Both actions of ALC were reversed by Mn supplementation. COX2 synthesis, as well as PGE2 and LHRH release were suppressed by ALC exposure, but Mn supplementation caused an increase in COX2 synthesis and subsequent PGE2 and LHRH release in the presence of ALC. Mn supplementation also ameliorated the action of ALC to delay puberty.
Does manganese protect against the effects of alcohol on hypothalamic puberty-related hormones?

Role of P-selectin (CD62) and glycoprotein (GP) Ibalpha in posttransfusion clearance of platelet concentrates (PCs) is unclear.', 'Platelet (PLT) activation in vitro was determined by flow cytometry using anti-CD62 and anti-GPIbalpha. PC clearance in vivo was evaluated in an animal model using rabbits with an inhibited reticuloendothelial system, as measured by 0.5-hour (R(0.5)), 24-hour (R(24)), and total (R( summation operator )) PLT recoveries, and survival time (ST). Correlations were analyzed between in vitro assays of PLT activation and in vivo clearance of conventional (Days 2-5), outdated (Days 7-8), and refrigerated PCs.', 'Binding of anti-CD62 to the PLT surface was significantly increased and of anti-GPIbalpha decreased in outdated and refrigerated PCs compared to conventional PCs. Negative correlation was observed between in vitro anti-CD62 binding and the fast (R(0.5)) PLT clearance, but not with delayed (R(24) and ST) clearance. In contrast, anti-GPIbalpha binding showed positive correlations with delayed but not with fast PLT clearance. Overall (R( summation operator )) clearance correlated better with anti-GPIbalpha than with anti-CD62 binding. CD62 density on the PLT surface was decreased after PC transfusion, whereas GPIbalpha density remained unchanged.
