In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Question: Context: This study examined the relationship between plasma cholesterol and circulating triiodothyronine and oestradiol in 561 adolescent girls aged 11-17 with eating disorders.', 'Plasma total cholesterol, high-density lipoprotein cholesterol, serum triodothyronine and oestradiol were measured at assessment, and historical weight data were obtained from growth charts provided by the school health services. Cholesterol levels were related to weight change, menstrual status and serum hormones.', 'Plasma total cholesterol levels of >5.0 mmol/L were found in 38% of the 77 girls who were premenarcheal, 32% of the 199 with secondary amenorrhoea and 17% of those who were still menstruating. These cholesterol levels were inversely related to serum oestradiol and triiodothyronine concentrations, but not weight change, in amenorrhoic girls and were positively related to body mass index and inversely related to weight loss and serum triiodothyronine in girls who were still menstruating.\Question: Is plasma cholesterol related to menstrual status in adolescent girls with eating disorders and weight loss?

Answer: Increased plasma total cholesterol was related to amenorrhoea in adolescent girls with eating disorders and weight loss. Oestrogens appeared to mediate the effect of starvation on cholesterol, most effectively in premenarcheal girls. Re-establishing menstruation is an important goal in the treatment of eating disorders, to avoid dyslipidaemia and the risk of future cardiovascular disease.


Question: Context: Phospholipid transfer protein (PLTP) transfers phospholipids between lipoproteins and plays an important role in HDL metabolism. PLTP exists as a high-activity and a low-activity form in the circulation. In vitro studies have shown that apolipoprotein (apo) E is involved in maintaining PLTP in the active form, while the low-activity form is associated with apo AI. We have therefore investigated whether plasma apo AI, B and E concentrations are important determinants of plasma PLTP activity in type 2 diabetes, a condition associated with increased plasma PLTP activity.', 'Plasma PLTP activity was assayed by measuring the transfer of radiolabelled phosphatidylcholine from liposomes to HDL; apo AI and B by rate nephelometry and apo E by a 2-point turbidimetric assay.', 'Type 2 diabetic patients (n = 230) had higher PLTP activity than controls (n = 97) (2374 +/- 628 nmol/mL/h versus 1862 +/- 585 respectively, p < 0.01). They also had increased fasting triglyceride and low HDL. Plasma apo B (p < 0.01) and apo E (p < 0.05) were increased, whereas apo AI was reduced (p < 0.01). Univariate analysis showed that plasma PLTP activity correlated mainly with apolipoproteins AI and E. Stepwise regression analysis showed that apo E was the main determinant of plasma PLTP activity, accounting for 23% of its variability in the diabetic subjects and 8% in the controls respectively.\Question: Is plasma apolipoprotein E concentration an important determinant of phospholipid transfer protein activity in type 2 diabetes mellitus?

Answer: The associations between plasma apo AI and E concentrations and PLTP activity suggest that these apolipoproteins are important regulators of PLTP activity in vivo. The increase in PLTP activity in type 2 diabetes is partly related to the changes in these apolipoproteins.


Question: Context: We investigated the association of KLOTHO gene single nucleotide polymorphisms (SNPs) with various laboratory data in 476 Japanese healthy subjects.', 'The genotyping of G-395A in the promoter region and C1818T in exon 4 was performed using PCR with confronting 2-pair primers assay.', 'Multivariate analysis adjusted for age demonstrated that in men, body-fat ratio was high, and HDL cholesterol level was low in A allele carriers of G-395A compared with GG. In women, glucose was high in A allele carriers of G-395A compared with GG, and also in T allele carriers of C1818T compared with CC. When divided into 2 groups according to age, in men <60 y, body mass index, body-fat ratio and waist circumference were high in A carriers of G-395A compared with GG. In women <60 y, bone mineral density was high in A allele carriers of G-395A compared with GG, and systolic blood pressure and glucose were high in T carriers of C1818T compared with CC.\Question: Are kLOTHO gene polymorphisms G-395A and C1818T associated with lipid and glucose metabolism , bone mineral density and systolic blood pressure in Japanese healthy subjects?

Answer:
KLOTHO gene SNPs G-395A and C1818T are associated with lipid metabolism in men, and glucose metabolism, bone mineral density and systolic blood pressure in women.
