The ratio of nonsynonymous (dN) to synonymous (dS) substitution rates, omega, provides a measure of selection at the protein level. Models have been developed that allow omega to vary among lineages. However, these models require the lineages in which differential selection has acted to be specified a priori. We propose a genetic algorithm approach to assign lineages in a phylogeny to a fixed n...

The study was conducted to evaluate the effects of different dietary oil sources supplementation on laying hens' performance and fatty acids profile of egg yolks. Seventy-two 23-week-old laying hens (Tetra-SL) divided into six experimental diets (four replicates and three birds per replication) in a completely randomized design for nine weeks. Experimental diets were included: 1) control (no oi...

BACKGROUND Many studies assessed the impact of marine omega-3 fatty acids on glycemic homeostasis and lipid profiles in patients with type 2 diabetes (T2DM), but reported controversial results. Our goal was to systematically evaluate the effects of omega-3 on glucose control and lipid levels. METHODS Medline, Pubmed, Cochrane Library, Embase, the National Research Register, and SIGLE were sea...

Natural selection operating in protein-coding genes is often studied by examining the ratio (omega) of the rates of nonsynonymous to synonymous nucleotide substitution. The branch-site method (BSM) based on a likelihood ratio test is one of such tests to detect positive selection for a predetermined branch of a phylogenetic tree. However, because the number of nucleotide substitutions involved ...

OBJECTIVE To investigate associations among serum 25-hydroxy-vitamin D (25-OH-D), folate, omega-6/omega-3 fatty acid ratio and bacterial vaginosis (BV) during pregnancy. METHODS Biospecimens and data were derived from a random sample (N = 160) of women from the Nashville Birth Cohort. We compared mean plasma nutrient concentrations for women with and without BV during pregnancy (based on Nuge...

OBJECTIVE To evaluate systematically the clinical efficacy of omega-3 polyunsaturated fatty acids (PUFAs) in the prevention of postoperative complications in colorectal cancer (CRC) patients. MATERIALS AND METHODS Published articles were identified by using search terms in online databases - PubMed, Embase, and the Cochrane Library - up to March 2016. Only randomized controlled trials investi...

Sepsis is a systemic inflammatory reaction, which is aggravated by aspects of the immune response that are thought to be inhibited by Omega-3 fatty acids. The aim of the present study was to determine if Omega-3 fatty acid could modulate immunological function and improve survival rate among septic patients with intestinal dysfunction. A total of 48 mechanically ventilated patients with intesti...

Here, we propose valley-selective excitations via a two-color $(\ensuremath{\omega}+2\ensuremath{\omega})$ laser field, made by superimposing two linearly polarized pulses at frequencies $\ensuremath{\omega}$ and $2\ensuremath{\omega}$. We have studied the intensity ratio between few-cycle pulse of an $2\ensuremath{\omega}$ laser, its enhancement factor employing time-dependent first-principles...
