Even though histamine plays an important role in human health, it has been associated with food intoxication and intolerance episodes. The most relevant, current state of knowledge regarding histamine's biochemical and health aspects is provided. Histamine levels are provided for 17 food groups, including 335 food types and 11,437 samples, allowing ...

Ultrastructural studies on zoosporogenesis of Halopteris filicina (Sphacelariales, Phaeophyta)
Abstract The development of the unilocular sporangia of Halopteris filicina (Phaeophyta) commences with the formation of the reproductive branchlets, the apical cells of which differentiate into spore mother cells. Afterwards, meiosis occurs, which becomes evident by the formation of typical synaptonemal complexes.

Thallus development inDictyopteris membranacea(Phaeophyta, Dictyotales)
The thallus ontogeny of Dictyopteris membranacea is the outcome of a highly co-ordinated series of cell divisions, which is completed at a long distance from the apex. Three types of “meristems” function: (a) the central apical initials, which give rise to the other meristems and to initial cells of the midrib; (b) the marginal apical initials, which ...
