It has long been recognized that the life history of a neuron can be characterized by a
temporal progression of transitions that may be con veniently (albeit somewhat arbitrarily) …

Apoptosis is a morphologically distinct form of programmed cell death that plays a major role
during development, homeostasis, and in many diseases including cancer, acquired …

The processes of cell division and cell death interact to generate the proper numbers and
types of cells during development and to maintain this balance in the mature animal. The …

Publisher Summary This chapter discusses the ecdysone receptors and their biological
actions. It also summarizes the insect endocrinology and the roles of these steroids in the …

Apoptosis is a major part of the normal development of many organ systems and tissues.
The zebrafish (Danio rerio) has become a useful model for studying early development, and …

SYNOPSIS. Studies of hormone receptors and the transcription factors that they induce are
providing new insights into the control of growth and metamorphosis of insects. The …

Hormones and neurohormones act on the nervous system to produce important changes in
behavior. Amine actions in the lobster nervous system and their possible relations to …

The immune system provides good models for cell death, a phenomenon now recognized to
be of fundamental importance in many fields of biology. Cell death is strikingly polymorphic …

The postnatal fate of the first‐generated neurons of the cat cerebral cortex was examined.
These neurons can be identified uniquely by 3H‐thymidine exposure during the week …

The exoskeleton of insects (cuticle) is an assembly of chitin and cuticle proteins. Its physical
properties are determined largely by the proteins it contains, and vary widely with …
