L\'{e}vy-based growth models
In the present paper, we give a condensed review, for the nonspecialist
reader, of a new modelling framework for spatio-temporal processes, based on
L\'{e}vy theory. We show the potential of the approach in stochastic geometry
and spatial statistics by studying L\'{e}vy-based growth modelling of planar
objects. The growth models considered are spatio-temporal stochastic processes
on the circle. As a by product, flexible new models for space--time covariance
functions on the circle are provided. An application of the L\'{e}vy-based
growth models to tumour growth is discussed.Comment: Published in at http://dx.doi.org/10.3150/07-BEJ6130 the Bernoulli

Comparison of geranylgeranyl and phytyl substituted methylquinols in the tocopherol synthesis of spinach chloroplasts
Geranylgeranyl substituted methylquinols are shown to be precursors of tocopherol biosynthesis in spinach chloroplasts as well as phytyl substituted ones. The geranylgeranyl substituted quinols are methylated even to a greater extent than the phytyl substituted ones. The connection to the so far known biosynthetic origin of -tocopherol is probably -tocotrienol which is hydrogenated to γ-tocopherol and then further methylated to -tocopherol
