Glutamine synthetase activity during embryonic and larval development of the silkworm Bombyx mori L. and role of a JH analogue [PDF]
Silkworm eggs of diapause nature were chilled or treated with hydrochloric acid. Glutamine synthetase activity in such treated eggs was present soon after the treatment, whereas in non-diapause eggs it was not detectable until 24 h after the start of ...

BackgroundAs a response to harsh environments, the crustacean artemia produces diapause gastrula embryos (cysts), in which cell division and embryonic development are totally arrested.

Biological characteristics of Grapholita molesta (Lepidoptera: Tortricidae) induced to diapause in laboratory. [PDF]
In southern Brazil, Grapholita molesta (Busck) (Lepidoptera: Tortricidae) uses diapause as survival strategy during the winter (May-August). In our study, we evaluated the effect of diapause on biological characteristics of the species for 4 months in ...

Embryonic diapause in the elasmobranchs
Embryonic diapause is a temporary suspension of development at any stage of embryogenesis, which prolongs the gestation period, allowing parturition to occur in conditions that are more suitable for newborns. This reproductive trait is widespread among all vertebrates, including elasmobranchs.

Embryonic diapause in the European roe deer (Capreolus capreolus) [PDF]
The first written reports on embryonic diapause in the European roe deer (Capreolus capreolus) date back to 1843 and 1854. While the rut takes place in July/August, rapid embryo elongation and implantation take place in December/January, after a five month period of embryonic diapause.

Cold tolerance of the eggs of the grasshopper, Chorthippus fallax (Zubovsky), was examined in the laboratory. Egg supercooling points varied from -6°C to -32.4°C and could be divided into two groups. The supercooling points of the higher SCP group ranged

Morphological types and seasonal variation in eggs of zooplankton species from bottom sediments in Bahia Blanca Estuary, Argentina [PDF]
Resting egg production is a survival mechanism in zooplankton species against adverse environmental conditions. Egg accumulation in the upper layer of the bottom sediments is fundamental to the resurgence of the populations of these species when ...

Distinct dormancy progression depending on embryonic regions during mouse embryonic diapause†
AbstractMany mammalian species undergo embryonic diapause and suspend development at the blastocyst stage before implantation, which is also known as delayed implantation. We studied the process of how mouse embryos enter a dormancy status at a cellular level.

How are pluripotent cells captured in culture? [PDF]
In mice, three pluripotent stem cell lines have been established from different stage of developing embryo, which are embryonic stem (ES) cell, post-implantation epiblast stem cell (EpiSC), and embryonic germ (EG) cell.
