Mll, Brg1 and Brm are vertebrate homologues of Drosophila trithorax group (trxG) genes. We isolated chicken Mll cDNA clones, and examined patterns of Mll, Brg1 and Brm expression in chick embryos. All three genes were expressed from embryonic stage 2 onwards. Mll transcripts were just detectable in all tissues by in situ hybridization, with highest level in dorsal neural tube and notochord. Brg...
San (Bushman) society in the Cape Colony was almost completely annihilated during the eighteenth and nineteenth centuries as a result of land confiscation, massacre, forced labour and cultural suppression that accompanied colonial rule. Whereas similar obliterations of indigenous peoples in other parts of the world have resulted in major public controversies and heated debate amongst academics ...
An attempt is being made to construct an FM broadcast receiver utilizing relatively few tubes but incorporating the principles of multipath interference reduction. The parts to be constructed are the i-f amplifier, a two-tube limiter, a discriminator and an audio amplifier stage. A bandwidth of 2 Mc for the limiter and discriminator was chosen after a study of multipath interference in cities s...
AIM This study aimed to investigate the effects of a new generation antiepileptic agent, levetiracetam, on the neural tube development in a chick embryo model that corresponds to the first month of vertebral development in mammals. MATERIAL AND METHODS Forty-five Atabey® breed fertilized chicken eggs with no specific pathogens were randomly divided into 5 groups. All of the eggs were incubate...
The article proposes a method for designing combustion chambers gas turbine engines based on combination of the use calculations in one-dimensional and three-dimensional formulation problem. This technique allows you to quickly design at initial stage creating development existing using simplified calculation algorithms. At final stage, detailed are carried out numerical calculations. includes ...
