Recent studies have shown that, in some species, xylem hydraulic conductivity (K(h)) increases with increasing cation concentration of xylem sap. Evidence indicates that K(h) increases as a result of the de-swelling of pit membrane pectins caused by cation neutralization of polygalacturonanes. We tested whether this ionic effect partly compensates for the embolism-induced loss of stem hydraulic...

Methicillin-resistant S. aureus (MRSA) are a threat to public health as they frequently reveal multidrug-resistant pattern. Researchers all over the world on an urgent hunt for new treatments help fight infections before antibiotics become obsolete, and some natural alternatives, such polyphenols, have already exhibited therapeutic properties. Therefore, this study aimed determine phenolic prof...

platanus orientalis l. (platanaceae) is a medicinal tree used in iranian folklore and traditional medicine as a pain and inflammation reliever. in this study, the polyphenolic and total extract of p. orientalis leaves were prepared and their antinociceptive effects were studied in mice using the acetic acid-induced writhing, formalin and light tail flick tests. both hydroalcoholic and polypheno...

The aim of this study was to evaluate the effect raw (RawBC) and iron (Fe)-modified biochar (FeBC) derived from Platanus orientalis Linn branches on plant growth, enzyme activity, bioavailability uptake As, Cd, Pb by rice in a paddy soil with continuously flooded (CF) or alternately wet dry (AWD) irrigation pot experiment. Application RawBC (3%, w/w) significantly increased pH, while FeBC decre...

BACKGROUND Peach allergy is prevalent, persistent, and potentially severe and as such is a target for immunotherapy. Our aims were to evaluate the profile of sensitization to Rosaceae allergens and the effects of sublingual peach immunotherapy on immunoglobulin (Ig) E levels to these allergens, to monitor for neosensitizations, and to check if this treatment modified other Rosaceae fruit and po...

The loss of chlorophyll and total leaf nitrogen during autumnal senescence of leaves from the deciduous tree Platanus occidentalis L. was accompanied by a marked decline in the photosynthetic capacity of 02 evolution on a leaf area basis. When expressed on a chlorophyll basis, however, the capacity for lightand C02-saturated O2 evolution did not decline, but rather increased as leaf chlorophyll...

The aim of this paper is to analyze the mechanical properties Robinia pseudoacacia L. (black locust), Platanus × hybrida Brot. (London plane), Ulmus pumila (Siberian elm), and Populus alba (white poplar), estimated using ultrasound wave equipment (USLab y Sylvatest Duo) impact (Microsecond Timer) on standing trees, felled logs specimens obtained from different parts trees. Bending strength, axi...
