Background: Cerebrovascular disorders are the second most common cause of cognitive decline. Aerobic exercises have been proved to improve cognitive functions through producing vascular changes. Objective: To assess and explain from physiological point of view the efficacy of aerobic exercise on cognitive changes of stroke patients. Methods: Thirty Egyptian patients with stroke in territory of ...

We investigated which parameters required by the MAESTRA model were most important in predicting leaf-area-based transpiration in 5-year-old trees of five deciduous hardwood species-yoshino cherry (Prunus x yedoensis Matsum.), red maple (Acer rubrum L. 'Autumn Flame'), trident maple (Acer buergeranum Miq.), Japanese flowering cherry (Prunus serrulata Lindl. 'Kwanzan') and London plane-tree (Pla...

Title of Document: EFFECTS OF NITROGEN AND CALCIUM ON PHOTOSYNTHESIS AND METABOLIC ACTIVITY IN ACER SACCHARUM IN THE CATSKILL MOUNTAINS. Shawna Joy Behling Directed By: Associate Professor Dr. Joseph Sullivan Plant Sciences and Landscape Architecture The Catskill Mountains in southern New York have received some of the most acidic rainfall in the country for the past 50 years. Acid deposition o...

The capture of patchily distributed nutrients by tree roots has received extensive research, but the fate of those nutrients has not. We performed experiments to determine if nutrient transport within tree species is preferentially transported from specific roots to specific branches. Saplings of five species with contrasting growth requirements were examined: two Betula species (B. papyrifera ...

Glucitol-core containing gallotannins (GCGs) are polyphenols containing galloyl groups attached to a 1,5-anhydro-d-glucitol core, which is uncommon among naturally occurring plant gallotannins. GCGs have only been isolated from maple (Acer) species, including the red maple (Acer rubrum), a medicinal plant which along with the sugar maple (Acer saccharum), are the major sources of the natural sw...

Understanding shifts in autumn phenology associated with climate changes is critical for preserving forest ecosystems. This study examines the changes in the leaf coloring date (LCD) of two temperate deciduous tree species, Acer palmatum (Acer) and Ginkgo biloba (Ginkgo), in response to surface air temperature (Ts) changes at 54 stations of South Korea for the period 1989-2007. The variations o...

in the last decade, frequency of late cold incidence has increased in the upland forest nurseries. the aim of present study was to reduce the damage caused by spring frost and to increase the efficiency of persian maple seedlings production in mountain nurseries. this study was conducted as split plot design with two main treatments and three replications in two consecutive years (2009-2010) in...

Plants extracts are good resources to find functional compounds for human health. The following eight plants were collected and total phenolic contents were determined. Acer psedo-siebolianum showed the highest phenolic contents, 16.4 mg/g, whereas Cercidiphyllum japonica showed the lowest contents, 1.9 mg/g. The DPPH free radical scavenging capacities of the plant extracts showed high activity...
