Diabetes is quickly becoming the most widespread disorder in the Western world. Among the most prevalent effects of diabetes is atherosclerosis, which in turn is driven in part by inflammation. Both insulin and Tumor Necrosis Factor-alpha (TNFα) increase the presence of Vascular Cellular Adhesion Molecule-1 (VCAM-1) expression. The aim of this study is to determine the effects of downregulating Extracellular signal-Regulated Kinase-2 (ERK2) and Akt on insulin and TNFa-stimulated VCAM-1 expression.

During Leica workshops for LMD users in Brazil, hosted by the Federal University of Paraná/UFPR (UFPR) at the Centro de Energia Nuclear na Agricultura/USP (CENA), the power of laser microdissection using the Leica LMD systems was demonstrated. One special focus was on plant dissection which needs a high laser power.
