Introdouction: Age estimation is an important issue in forensics, particularly for treatment planning and determining patients’ rights. Radiographic evaluation of the third molar developmental stage is a significant criterion for age estimation. The pattern of tooth development is largely heritable and varies from race to race. The objective of this study was to radiographically examine and com...

sunflower has many dry forage yields and is richer than corn in inorganic matter, protein and calcium. therefore, use of this forage in livestock diets can be valuable for elimination of food poverty. in order to determine the best harvest stage for sunflower silage, an experiment was conducted in 2007-2008 at agricultural faculty of shahid chamran university of ahvaz. a randomized complete blo...

The anther-specific gene LLA1271 isolated from lily (Lilium longiflorum Thunb.) anthers is novel and exists in two forms. The protein encoded by LLA1271 may represent an adhesin-like protein first found in higher plants. The protein contains a typical N-terminal signal peptide followed by a highly conserved repeat domain. The LLA1271 gene is temporally expressed at the phase of microspore devel...

Abstract Einkorn ( Triticum monococcum L.) can be applied as a model species for cereal genomic studies due to its small genome size and high level of polymorphism. The in vitro somatic tissue culture protocol einkorn was significantly improved recently, however the androgenesis remained an unresolved research topic. Five different pre-treatments were compared study effects stress on efficiency...

background: timing of the first zygotic cleavage is an accurate predictor of embryo quality. embryos that cleaved early (ec) have been shown to exhibit higher developmental viability compared to those that cleaved at a later period (lc). however, the viability of ec embryos in comparison to lc embryos after vitrification is unknown. the present study aims to investigate the post-vitrification d...
