Proximal aortic diameter, including aortic root (AoR) diameter, has been inversely related to pulse pressure in cross-sectional studies. So, investigators have hypothesized that a smaller AoR diameter may increase the risk of developing hypertension. Prospective studies are lacking to test this hypothesis. We measured AoR diameter in 3195 Framingham Study participants (mean age: 49 years; 57% w...

Aviecennia marina (Avicenniaceae) is an endemic plant that widely distributed in the Southern parts of Iran. This plant has been used as treatment of rheumatism arthritis among the inhabitants of Southern parts of Iran. The Avicennia marina hydroalcoholic extract was prepared and its protective efficacy was investigated using measurement of ankle diameter, total WBC and RBC count, ESR, and Pro-...

initial growth of quercus castaneifolia (c.a.meyer.) seedling in competition with rubus fructicosus l. was investigated in a caspian lowland intervened forest located in noor city, north of iran. the research was conducted as factorial experiment in three replications. for this purpose, seedlings of 3 and 5 mm in collar diameter (cd) were planted in areas a (covered with rubus), b (without rubu...

hyrcanian forests are the most valuable forests in the north of iran and industrial harvesting occurs only in this area. it is a productive region near the southern coast of caspian sea. in these forests mixed beech stands mostly shown uneven-aged structure that is managed under selection system. in order to determine the priority of uneven aged method not only from an ecological view, but also...

BACKGROUND To investigate the effect of intra-abdominal volume increment (IAVI) on intra-abdominal hypertension (IAH) in the kidneys. METHODS Eight minipigs were successfully established as IAH models and were randomly divided into two groups: the IAVI group and the sham-operated group. The intravesicular pressure, inferior vena cava pressure and urine volume were measured before shock, 2 h a...

The aim of this study is to relate initial stand density and thinning intensity tree diameter, height, volume increment based on continuous 30-year observations in experimental stands Scots pine (Pinus sylvestris L.). experiments were established 1990 1992, the model each trial comprised five variants: control four plots with densities up 3.0–4.4, 2.0–2.4, 1.0–1.2, 0.5–0.6 thousand trees per he...

A series of trials examining fertilizer-shading interactions on the island of Leyte (Philippines, 11°N) revealed that the endemic dipterocarp mayapis (Shorea palosapis) benefits from shade trees, either directly above or to the east, during the early stages of plantation establishment. Although it can attain 2 cm/year diameter increment in plantations, mayapis exhibits poor growth and survival ...

Population size and structure of 52 isolated Nothofagus fusca stands were investigated in the lower Otira Valley, 3-6 km from a major population centre in the upper Taramakau catchment. The approximate age of N. fusca pioneer trees, estimated from partial increment cores and calculations based on diameter growth rates, indicated that nearly all isolated stands originated after 1600 AD, predomin...

The spruce beetle (Dendroctonus rufipennis) is known for extensive outbreaks resulting in high spruce mortality, but several recent outbreaks in the western United States have been among the largest and most severe in the documentary record. In the Pinaleño Mountains of southeast Arizona, U.S.A., an outbreak in the mid-1990s resulted in 85% mortality of Engelmann spruce >7 cm diameter. To put t...
