OBJECTIVE Cysteinyl leukotrienes are involved in inflammation and possibly in early carotid atherosclerosis. We tested the hypothesis that the -444 A/C and -1072 G/A polymorphisms of the leukotriene C(4) synthase associate with risk of ischemic cerebrovascular disease. METHODS AND RESULTS We genotyped 10 592 individuals from the Danish general population, the Copenhagen City Heart Study. Duri...

Wheat grown in Mn-deficient soil has been widely observed to produce much reduced yields. Breeding for Mn-efficient wheat genotypes adapted to Mn-deficient soils would represent a long-term solution for wheat agronomy. To characterize the physiological basis of Mn efficiency in wheat genotypes would facilitate the breeding programs for producing Mn-efficient wheat. Using a solution culture and ...

Background & AimsHBsAg proteins are useful to identify HBV inactive carriers (ICs), but data on chronic hepatitis D (CHD) scarce. This study aimed describe HBsAg composition in CHD, its changes during the evolution and potential association with clinical outcomes. Besides, we assess of across different genotype validate previous results an independent cohort.MethodsQuantitative (qHBsAg), medium...

BACKGROUND Hepatitis C virus (HCV) genotype-3a infection is now the dominant strain in South Asia and the UK. Characteristic features include a favourable response to therapy; the reasons for this are unknown but may include distinct genotype-3a-specific T cell immunity. In contrast to genotype-1 infection, T cell immunity to this subtype is poorly defined. OBJECTIVES The aims of the study we...

BACKGROUND Catechol-O-methyltransferase (COMT) is the principal enzyme in the conjugation pathway for hydroxylated estrogens. We hypothesize that blood 17beta-estradiol (E(2)) and estrone (E(1)) levels in postmenopausal women receiving an oral E(2) preparation are dependent on the enzyme activity of COMT. METHODS To determine the influence of this enzyme on E(2) serum levels three groups of 1...

Apolipoprotein E (apoE) genotypes were determined in a random subset of 1041 subjects enrolled in the Framingham Offspring Study by using DNA amplification followed by restriction isotyping. The results were compared with the apoE phenotypes previously assessed by isoelectric focusing. Discrepancies in apoE allele assignment were found in 98 subjects (9.4%). Both genotype and phenotype were rea...
