Factors determining the degree of dietary generalism versus specialism are central in ecology. Species that are generalists at the population level may in fact be composed of specialized individuals. The optimal diet theory assumes that individuals choose diets that maximize fitness, and individual specialization may occur if individuals' ability to locate, recognize, and handle different food ...

five treatments including conway medium, media containing 0.1, 0.17, 0.3 and 0.5 mg l-1 ferrous (fe; in the first experiment), media with 1, 1.26, 1.59, 2 mg l-1 concentrations of phosphorous (p; in the second experiment) and a pure sample of tetraselmis suecica were cultured under laboratory conditions. growth rate of the algae was determined using the optical density method at 750 nm and numb...

A significant role for micro (mi)RNA in the regulation of gene expression in tumours has been recently established. In order to further understand how miRNA expression may contribute to prostate tumour growth and progression, we evaluated expression of miRNA in two invasive prostate tumour lines, PC3 and DU145, and compared it to that in normal prostate epithelial cells. Although a number of mi...

This Article contains errors in Figs 4,6 and 7 that were introduced during the production process. In Fig. 4j, the lane labels on the blot should read in order ‘InputNo Ab-IgG-Flag’. In Fig. 6i, the x axis label ‘WT PP2A’ of the two graphs should read ‘DN PP2A’. Finally, in Fig. 7a, the maximal cell number reported in the table for the injection of CCS and HT29 should read ‘1 105’ and not ‘1 10...

background: the aim of this study was optimization of the polyfect gene delivery method of pcdna3.1 expression vector transfected with the mouse pdx-1 gene in three different kinds of mesenchymal stem cells and hepa cells as well as comparison of transfection efficiency leading to expression of the mentioned gene in the cell types used. materials and methods: rat bone marrow-derived mesenchymal...

The phytoplankton composition of Sawa Lake was studied monthly for 18 months, from October 1999 to March 2001. A net (20 $) used collect samples. total 51 algal taxa identified belong diatoms (Bacillariophyceae), blue greens (Cyanophyceae), green algae (Chlorophyceae) and euglenoids (Euglenophyceae). Diatoms were dominated in species number (64.7%) cell (68.6%) followed by (23.5%) (15.5%), the ...
