The effects of light intensity (µ mol m-2 s-1) and different levels of Nitrogen was made on the biomass and lipid of microalgae Chaetoceros calcitrans under  laboratory conditions in the north of Iran in 2016. The pure strand of C. calcitrans with F/2 media (8 sets of 3 flasks) were placed in front of the light source at values of 80, 160, and 240 µ mol m-2 s-1. The cell count was collected in ...

OBJECTIVE The aim of this study is to analyze the effect of light deprivation on the expression of vascular endothelial growth factor (VEGF) and neovascularization in the retina of neonatal rats. MATERIALS AND METHODS Thirty-six neonatal SD rats (male and female) were used in this study. These rats were numbered randomly and assigned into 3 groups (12 rats in each group), ie. 10-day group (ro...
