In recent years there is growing interest on the role of long chain omega-3 polyunsaturated fatty acids (omega-3 LC-PUFA) in pregnancy and the growth and development of the offspring. We aim to characterize and provide baseline data on the intake of LCPUFA (omega-3 and omega-6) in a prospective cohort of 829 pregnant Indian women and report associations between LCPUFA intake and erythrocyte mem...

Omega-3 fatty acids play critical roles during fetal growth and development with increased intakes associated with improved maternal-fetal outcomes. Omega-3 fatty acid intake in Western diets is low, and the impact of socioeconomic factors on omega-3 fatty acid intake in pregnant women and women of childbearing age has not been reported. We used the National Health and Nutrition Examination Sur...

Codon-based substitution models have been widely used to identify amino acid sites under positive selection in comparative analysis of protein-coding DNA sequences. The nonsynonymous-synonymous substitution rate ratio (d(N)/d(S), denoted omega) is used as a measure of selective pressure at the protein level, with omega > 1 indicating positive selection. Statistical distributions are used to mod...

The accurate partitioning of Firmicute plasmid pSM19035 at cell division depends on ATP binding and hydrolysis by homodimeric ATPase delta(2) (ParA) and binding of omega(2) (ParB) to its cognate parS DNA. The 1.83 A resolution crystal structure of delta(2) in a complex with non-hydrolyzable ATPgammaS reveals a unique ParA dimer assembly that permits nucleotide exchange without requiring dissoci...

The antitumor effect of the type I IFN, IFN-omega, was evaluated in both in vitro and in vivo studies of human cancer. For these studies, the cDNA for human IFN-omega was cloned into a eukaryotic expression plasmid DNA (pDNA) driven by the cytomegalovirus promoter. Supernatants from UM449 cells transfected in vitro with IFN-omega pDNA had antiproliferative effects on 11 of 13 human tumor cell l...

BACKGROUND The aim of the current prospective, randomized control study was to investigate the effect of dietary omega-3 polyunsaturated fatty acids plus vitamin E on the immune status and survival of well-nourished and malnourished patients with generalized malignancy. METHODS Sixty patients with generalized solid tumors were randomized to receive dietary supplementation with either fish oil...

OBJECTIVE Adiponectin is a unique anti-atherogenic adipocytokine. Regulation of adiponectin secretion is dysfunctional in cardiovascular diseases. The current trial study assessed the effects of omega-3 fatty acids with or without vitamin E on adiponectin gene expression in peripheral blood mononuclear cells and serum adiponectin and adipocyte fatty acid-binding protein (A-FABP; also called ap2...

BACKGROUND Polycystic ovary syndrome (PCOS) is a common endocrine disorder associated with increased risk of cardiovascular disease. The purpose of this study was to investigate the ef¬fects of omega-3 fatty acids on serum paraoxonase 1 activity and lipids ratios in polycystic ovary syndrome. METHODS This double-blind randomized controlled clinical trial was conducted on 64 PCOS pa¬tients wit...

BACKGROUND Greater fish and omega-3 (n-3) polyunsaturated fatty acid (PUFA) intake may reduce dementia risk; however, previous studies have reported conflicting results, which were largely based on short-term follow-up. OBJECTIVE The objective was to study the dietary consumption of fish and omega-3 PUFAs in relation to long-term dementia risk. DESIGN We studied 5395 participants aged > or ...
