Rotifers from diapausing, fertilized eggs: Unique features and emergence

Viability of invertebrate diapausing eggs collected from residual ballast sediment

Natural or anthropogenic movement of sediments may be an important vector for the dispersal of invertebrate resting stages between water bodies. Here we record the presence of invertebrate diapausing eggs in residual sediments from transoceanic vessels and explore whether these may pose an invasion risk. Viability of diapausing eggs was explored under light and dark conditions using sediment co...

Purification and Characterization of an Antioxidant Protein from Fertilized Eggs

Free radicals may attack cells or tissue, leading to chronic diseases, and antioxidant consumption is potentially useful for removing free radicals. Egg proteins may be used as potential sources of antioxidant considering their ability of scavenging free radicals to apply for food or cosmetics industry. In this study, we obtained a natural antioxidant protein from fertilized eggs, which was a d...

Pronuclear Microinjection of Rabbit Fertilized Eggs

Although, the first transgenic animal was produced more than 30 years ago, there are still many factors limiting efficiency of transgenesis. One of them is the low rate of transgene incorporation into the genome of microinjected eggs. This mini-review summarizes recent research methods based on pronuclear microinjection of rabbit fertilized eggs in order to reach higher efficiency of transgene ...

Electrophoretic movement of fertilized sea-urchin eggs.

The eccentric shift of the sea-urchin egg within the fertilization membrane under an electric field was analysed by measuring the electrophoretic mobility of the isolated fertilization membrane and that of the egg deprived of the fertilization membrane. In addition, the migration speed of the egg proper was measured within the fertilization membrane under the conditions that: either (1) the mov...

Factors Influencing Adult Emergence from Diapausing Sorghum Midge, Contarinia sorghicola (Diptera: Cecidomyiidae
