The CORE Diabetes Model allows the calculation of long-term outcomes, based on the best data currently available. Diabetes management strategies can be compared in different patient populations in a variety of realistic clinical settings, allowing the identification of efficient diabetes management strategies.

The CORE Diabetes Model provides an accurate representation of patient outcomes when compared to 66 studies of diabetes and its complications. Model flexibility ensures it can be used to compare diabetes management strategies in different cohorts across a variety of clinical settings.

Background & Aims-We recently identified lysophosphatidic acid (LPA) as a potent antiapoptotic agent for the intestinal epithelium. The objective of the present study was to evaluate the effect of octadecenyl thiophosphate (OTP), a novel rationally designed, metabolically stabilized LPA mimic, on radiation-induced apoptosis of intestinal epithelial cells in vitro and in vivo

SummaryThe Arabidopsis gene encoding the key¯avonoid biosynthesis enzyme chalcone synthase (CHS) is regulated by several environmental and endogenous stimuli. Here we dissect the network of light signalling pathways that control CHS expression in mature leaves using cryptochrome (cry) and phytochrome (phy) de®cient mutants. The UV-A/blue light induction of CHS is mediated principally by cry1, but neither cry1 nor cry2 is involved in UV-B induction or in the UV-A and blue light signalling pathways that interact synergistically with the UV-B pathway to enhance CHS expression. Moreover, these synergistic responses do not require phyA or phyB. Phytochrome is a positive regulator of the cry1 inductive pathway, mediating distinct potentiation and coaction effects. A red light pretreatment enhances subsequent cry1-mediated CHS induction. This potentiation is unaltered in phyA and phyB mutants but much reduced in a phyA phyB double mutant, indicating that it requires principally phyA or phyB. In contrast, the cry1-mediated induction of CHS, without pretreatment, is much reduced in phyB but not phyA mutants, indicating coaction between cry1 and phyB. Further experiments with phyde®cient mutants demonstrate that phyB is a negative regulator of the UV-B inductive pathway. We further show that phyB acts upstream of the points of interaction of the UV-A and blue synergism pathways with the UV-B pathway. We propose that phyB functions to balance¯ux through the cry1 and UV-B signalling pathways.
