Background: The aim of this study was evaluation of developmental rate and Bax, Bcl-2 and ErbB4 genes expression following re-vitrification in compact and early blastocysts stages. Materials and Methods: 5-8 cell embryos were collected from female mature mice, 60-62 hours post hCG injection. The embryos were divided to five groups including: fresh, vitrified at 5-8 cells, vitrified at blastocys...

Support Vector Regression (SVR) combined with Invasive Weeds Optimization (IWO), standalone SVR, and Radial Basis Function Neural Networks are applied to estimate channel sinuosity in perennial rivers. With this aim, a dataset 132 data related geomorphologic data, corresponding 119 streams, is considered. Bayesian Mutual Information theory used determine the parameters affecting reveal that ban...

Abstract With the operation of Three Gorges Project (TGP) and reservoirs in upper reaches Yangtze River, sediment transport reduced significantly lower River since 2003, leading to great changes relationship between flow sediment. In order study variation characteristics river channel under new conditions, at main hydrological stations, amount intensity erosion/deposition Hukou-Jiangyin reach, ...

some recent studies have revealed the relationship among excess ferritin, coronary heart disease, and insulin resistance. to assess the association between serum ferritin concentration and impaired fasting glucose, this study was designed. a total of 187 people including 91 impaired fasting glucose (ifg) subjects and 96 normal glucose subjects who had been recognized in a large epidemiological ...

Land use practices in Colorado during the last two centuries altered the supply of sediment and water to many channels in the upper South Platte Basin. As a result of increased supply of sediment and mobility and reduced peak flows, the characteristics of pools associated with channel constrictions, referred to as forced pools, may have been altered. Increased supply of sediment and reduced tra...
