EFFECT OF THALIDOMIDE ON EMBRYONIC AND POST-EMBRYONIC DEVELOPMENT OF THE CHICK
Canadian Journal of Animal Science, 1968Breeding hens were fed diets containing 0, 1.32 or 2.64 g thalidomide (TLD) per kg of feed. There were no malformations in any of the 330 chicks and none in the unhatched embryos when the dam diet contained an adequate level of niacin, but day-old body weights of chicks from TLD-fed dams were consistently lower in comparison with chicks from untreated

Post-embryonic development in the ventral cord of Caenorhabditis elegans
Philosophical Transactions of the Royal Society of London. B, Biological Sciences, 1976Abstract 56 nerve cells are added to the ventral cord and associated ganglia of Caenorhabditis elegans at about the time of the first larval moult. These cells are produced by the uniform division of 13 neuroblasts followed by a defined pattern of cell deaths.

Morphological Cell Death in the Post-embryonic Development of the Insect Optic Lobes
Nature, 1968THE incidence of cell death among differentiating cells of the embryonic vertebrate central nervous system is well documented1–3, and there is evidence that in some cases its occurrence is influenced by the peripheral load encountered by the outgrowing fibres1–5.

THE POST-EMBRYONIC DEVELOPMENT OF THE COMMON PANDALIDS OF BRITISH COLUMBIA
Contributions to Canadian Biology and Fisheries, 1931The paper deals with the post-embryonic development of the five most common pandalids in British Columbia, namely. Pandalus danae, Pandalus borealis, Pandalus hypsinotus, Pandalus platyceros, and Pandalopsis dispar, in greatest detail with the first species, with which the others are compared. The first stage of post-embryonic development was obtained

The Embryonic and Post-Embryonic Development of Rhabditis Teres (a. Schneider)
Nematologica, 1962A new technique, using garden snail's mucus, was employed for handling nematode eggs. Fertilization preceded the second maturation division. After fusion of the male and female pronuclei the zygote divided into two 1/2-blastomeres of unequal size. A coeloblastula was formed.

ABSTRACT 1. The localization of alkalii1e phosphatase during the post-embryonic development of Drosophila melanogaster has been described. 2. In the larvae, nuclear phosphatase is always demonstrable, but cytoplasmic phosphatase shows a more restricted distribution.
