Whereas the impacts of N deposition on forest ecosystems have been well studied in remote areas predominantly forested landscapes, we know relatively less about forests heavily human-modified landscapes. We influence adjacent land use, local point sources, and woodlot stand structure subcanopy transport enrichment via throughfall three fragments southern Lower Michigan, USA. found that one site...

background : cockroaches have been recognized as a powerful indoor allergen. cockroach allergy can be a major factor in seri­ous asthma and nasal allergy. bioinformatics tools have been developed to identify potential allergens. the present study was conducted to identify potential allergens in  periplaneta americana (linnaeus). methods : the study focused on the identification of potential all...

In the Arbutus Lake Watershed in the Adirondack Mountains, New York, two nearly adjacent catchments (14 and 15) varied significantly in volume-weighted stream water nitrate (NO3) export (54 and 17 mequiv. L–1, respectively; P < 0.001). The most notable differences between the catchments were that Catchment 14 had significantly higher soil Ca concentrations and patches of basswood (Tilia america...

In vitro propagation of Tilia platyphyllos Scop. has been achieved by axillary shoot proliferation and somatic embryogenesis. The influence of tree age, explant source, genotype, and phytohormones on micropropagation of juvenile and mature trees of Tilia platyphyllos has been investigated. Nodal segments and shoot tips were used as initial explants for axillary shoot proliferation. Low concentr...

the impact of climatic variations on basal area growth of basswood (ba) (tilia americana l.), american beech (be) (fagus grandifolia enrh.), bitternut hickory (bh) (caria cordiformis (wang.) k. koch), largetooth aspen (la) (populus grandidentata michx.), red maple (rm) (acer rubrum l.), red oak (ro) (quercus rubra l.), sugar maple (sm) (acer saccharum marsh.), and white ash (wa) (fraxinus a...

Abstract Anti-nociceptive activity of aerial parts of Phytolacca americana were investigated, using the hot plate method in mice. Results of the present study showed that the aqueous methanolic extract of aerial parts of P. americana produced a statistically significant increase in pain threshold after 30 min, in comparison with the control, at adose of 190 mg kg-1 (P 0.05). The anti-nociceptiv...

Tilia species have been used in Asia, Europe and in America to treat anxiety and also for the treatment of colds and inflammation. The oxygen reactive species (ROS) (hydrogen peroxide (H2O2) and the superoxide anion (O2) are involve in the balance cell proliferation/death in lymphocytes. It was reported the presence of flavonoids in Tilia species which possess antioxidant properties. The aim of...

Variations in fruits morphology of Tilia spp. were studied along longitudinal and altitudinal range. Ten populations of Tilia spp.from Golestan, Mazandaran and Gilan Provinces (N. Iran) were selected. After biometrical measurements and Scanning Electron Microscopic (SEM), Cluster Analysis divided the population into seven groups. Discriminat Analysis showed that among all traits studied, size o...
