Background & Aims: Postprandial hyperglycemia results in the development of chronic complications. Therefore, its control is critical in the treatment of diabetes. One of the main therapeutic approaches for reducing postprandial hyperglycemia is to reduce the absorption of carbohydrates by enzyme inhibitors such as Acarbose which have already been clinically used as a medicine for diabetic pati...

The anatomical and morphological leaf traits as well as leaf inclination and orientation per different leaf age cohort of Quercus ilex, Phillyrea latifolia and Cistus incanus growing in the Mediterranean maquis along Rome’s coast-line (Italy) were investigated. Specific leaf weight (SLW), total leaf thickness (L), leaf density index and leaf inclination (a) changed according to leaf age. The ma...

Two and three years after the outplanting of 1-O northern red oak (Quercus rubra, NRO) and white oak (Q. ulba, WO) nursery stocks, the highest net photosynthetic rates (A-) were observed from seedlings growing on a clearcut site followed by those under a pine stand. Both NRO and WO seedlings under a hardwood stand had A, less than 10% of the full sun seedling A,,. Oaks grown under hardwoods inc...

Several hurricanes struck Florida, U.S. in 2004 and 2005 causing widespread damage to urban and rural areas. We measured the impacts of five of these hurricanes on the urban forest and combined these results with four other hurricanes to present an assessment of wind resistance for southeastern United States coastal plain tree species. Urban forest loss was positively correlated with wind speed...

Quercus ellipsoidalis (Hill’s oak), an endemic of east-central North America, is morphologically similar to Q. coccinea (scarlet oak) and is subsumed into that species in several floristic treatments. This study uses data from more than 250 amplified fragment length polymorphism (AFLP) markers to investigate whether Q. coccinea and Q. ellipsoidalis are genetically distinct from one another. Whe...

We measured gas exchange and various leaf parameters of ash (Fraxinus angustifolia Vahl.) and oak (Quercus robur L.) in the high canopy and of lime (Tilia cordata Mill.) in the lower canopy of a planted, 120-year-old floodplain forest in southern Moravia, Czech Republic. The high-canopy leaves of F. angustifolia and Q. robur had nitrogen concentrations on a leaf area basis (N(area)) that were t...
