Proportions ofaxial elements without any spatial contacts with rays were investigated. Non-contact rates between rays and fusiforrn initials or axial parenchyma strands were examined in tangential sections of cambial or axial parenchyma zones in 21 hardwood species . The noncontact rates were very different among species, ranging from 0% to 76%. Serial trans verse sections of xylem were used to deterrnine the non-contact rates between rays and wood fibers in 3 of the 21 hardwood species having high non-contact rates of parenchyma strands . The noncontact rate of wood fibers was 49% in Albizia julibrissin (non-storied cambium), 30% in Paulownia tomentosa (non-storied cambium), and 52% in Pterocymbium beccarii (storied cambium). Tangential seetions of three softwood species, Pinus thunbergii, Cryptomeria japonica, and Chamaecyparis obtusa were used to investigate the contacts between rays and tracheids. All tracheids in the three species had contact with at least one ray, ranging from 1 to 15 rays.

Type II diabetes is a metabolic disease mediated through multiple molecular pathways. Here, we report anti-diabetic effect of a standardized isolate from a fossil material - a mineraloid leonardite - in in vitro tests and in genetically diabetic mice. The mineraloid isolate stimulated mitochondrial metabolism in human fibroblasts and this stimulation correlated with enhanced expression of genes coding for mitochondrial proteins such as ATP synthases and ribosomal protein precursors, as measured by DNA microarrays. In the diabetic animal model, consumption of the Totala isolate resulted in decreased weight gain, blood glucose, and glycated hemoglobin. To our best knowledge, this is the first description ever of a fossil material having anti-diabetic activity in pre-clinical models.
