peripheral (autonomic and somatic) nervous systems. In the autonomic (sympathetic and parasympathetic) nervous system, acetylcholine is released from all preganglionic neurons, as well as from postganglionic parasympathetic neurons. Degradation of acetylcholine by the enzyme acetylcholinesterase occurs in the synapse between the presynaptic and postsynaptic membranes. There are two types of pos...

many cell lines, when cultured under proper conditions, can form three dimensionalstructures called multicellular spheroids. these spheroids resemble in vivo tumor models in severalaspects. therefore, studying growth characteristics and behavior of spheroids is beneficial inunderstanding the behavior of tumors under various experimental conditions. in this work, we havestudied the growth proper...

and lines of rhymed prose make it his longest work. *Ḥanukka-nāma (The Book of Hanukah), his other long narrative, is an account of the Maccabees’ successful military campaign against the Seleucid dynasty in the second century B.C.E. The extant manuscript copies are incomplete; in the introduction, however, Ben Samuel expresses his desire to continue in the tradition, begun by *Shāhīn in the fo...

This paper overviews the present status on therapy of regenerative medicine which is based on tissue engineering. Tissue engineering is a biomedical form which enables cells to promote their proliferation and differentiation, resulting in induction of tissue regeneration. The scaffold of 3-dimensional porous material for cells with or without the controlled release system of growth factor is ap...
