Thirty-one carbanilate derivatives were assayed for their capabilities to inhibit the ATPase activity of a plasma membrane fraction from Acer pseudoplatanus cells. At a concentration of 100 micromolar, nine compounds strongly inhibited the ATPase activity, with I(50) ranging from 14.5 micromolar to 35 micromolar. These molecules were also inhibitory to plasma membrane ATPases of other origins: ...

A study of 50 sugar maples {Acer saccharum) along Gates Mills Boulevard in Gates Mills, Ohio, showed that a tree's sap-sugar concentration tended to increase with decreasing tree health and increasing soil salt concentration. Relative tree health was determined by growth ring analysis. Salt concentration in soil was determined by measuring soil extract conductivity. Extract conductivity correla...

The dependence of vegetation attenuation on propagation geometry has been experimentally investigated at SHF band for isolated single trees. Two measurement heights (Trunk and Canopy) have been used in these experiments that involve three fully foliated trees, Common Whitebeam (Sorbus aria), Silver Maple (Acer Saccharinum) and Common Hazel (Corylus Avellana). Result shows that apart from freque...

intestinal pseudo-obstruction is a condition in which the intestine’s ability to push food through is reduced. it often leads to the dilation of the various parts of the bowel. it can be idiopathic or inherited from a parent, or caused by another disease. we report a rare case of human immunodeficiency virus (hiv) infection in a 3-year-old boy who referred with acute abdominal pain, and was lat...

background: phic31 integrase is a dna site-specific recombinase integrates dna into the chromosomes between the two sites of attb and attp. several pseudo attps have been identified in mammalian genomes with critical features for long-term expression of transgene. in this manuscript, we report a novel intrinsic pseudo attp site named chol1 in the chinese hamster genome implementing an inverse p...

In recent years, enterprises are facing the impact from the Financial Tsunami, factories moved outward, high production cost, shorter product life cycle, larger customization and global fierce competition. In order to survive, enterprises have to circulate all kind of information within the enterprise and supply chain to leverage the operation. This article presented five case studies including...

There is an error in the first sentence of the fourth paragraph in the Procedure section of the Methods. The data are available from Open Science Framework instead of Dataverse. The correct sentence is: The questionnaire programmed in Qualtrics was offered in Dutch and took on average 15 minutes to complete (on a notebook (Acer) or an iPad; the exact questionnaire in Dutch are available via htt...

Two new stilbene glycosides, 5-O-methyl-(E)-resveratrol 3-O-beta-d-glucopyranoside (1) and 5-O-methyl-(E)-resveratrol 3-O-beta-D-apiofuranosyl-(1-->6)-beta-d-glucopyranoside (2), were isolated from the leaves of Acer mono, along with seven known compounds. Among these compounds, 1, 2, and quercetin (3) showed significant hepatoprotective activities against H(2)O(2)-induced toxicity in primary c...

Selection cutting is a treatment that emulates tree-by-tree replacement for forests with uneven-age structures. It creates small openings in large areas and often generates a more homogenous forest structure (fewer large leaving trees and defective trees) that differs from old-growth forest. In this study, we evaluated whether this type of harvesting has an impact on genetic diversity of sugar ...

Upland forests of the southern Lake Superior region are diverse and contain a shifting mosaic of eastern hemlock [Tsuga canadensis (L.) Carr.] and northern hardwood forests dominated by sugar maple (Acer saccharum Marsh.). In this study, we survey the relative effects of management practice (old growth vs. managed), forest cover type (hemlock vs. northern hardwood), and soil great group (Entic ...
