The Embryology of Alyssum

Cellular compartmentation of nickel in the hyperaccumulators Alyssum lesbiacum, Alyssum bertolonii and Thlaspi goesingense.

Nickel uptake and cellular compartmentation were investigated in three Ni hyperaccumulators: Alyssum bertolonii (Desv), Alyssum lesbiacum (Candargy) and Thlaspi goesingense (Hálácsy). The three species showed similar hyperaccumulation of Ni, but T. goesingense was less tolerant to Ni than the two Alyssum species. An addition of 500 mg Ni kg(-1) to a nutrient-rich growth medium significantly inc...

Embryology of the eye

Afin d’appréhender les mécanismes qui sous-tendent la physiologie de la vision, la connaissance des bases embryologiques du développement de l’œil et de ses annexes est un prérequis indispensable. La morphogénèse oculaire débute au cours de la quatrième semaine de vie embryonnaire, alors que l’ébauche oculaire s’individualise des diverticules latéraux du cerveau antérieur par des mouvements mor...

Embryology of the eye.

A brief description of the basic patterns of mammalian development of the eye is presented based on events as they occur in human beings. The emphasis is not on the details of this development, but rather on its organization and timing, with a figure of comparative development providing a comparison of similar events in man, rat, mouse, and chick.

coloured plates. These are of the very greatest value in assisting one to follow the meaning of the letterpress. This, we think, is particularly the case in the chapter dealing with Meckel's diverticulum. The volume is one that should prove itself of great value to surgeons and physicians and as a book of reference. As would be expected the publishers have done their share of the work in a most...
