This research was carried out to evaluate the effect of two mycorrhiza species on growth, yield and oil content of geranium under salinity stress. The experiment was done at research greenhouse of Faculty of Agriculture, Lorestan University, Iran, in 2014. Four levels of substrate (sterilised and non-sterilised control soil and sterilised soil inoculated with Glomus mosseae or G. intraradices),...
A full understanding of the growth and distribution tree roots is conducive to guiding precision irrigation, fertilization, other agricultural work during production. Detecting with a ground-penetrating radar repeatable detection method that does no harm earth surface roots. In this research, rapid accurate automatic was conducted on hyperbolic waveforms formed by root targets in B-scan images ...
BACKGROUND Aortic-root dissection is the leading cause of death in Marfan's syndrome. Studies suggest that with regard to slowing aortic-root enlargement, losartan may be more effective than beta-blockers, the current standard therapy in most centers. METHODS We conducted a randomized trial comparing losartan with atenolol in children and young adults with Marfan's syndrome. The primary outco...
To evaluation of genetic parameters of rooting traits in 50 doubled haploid barley lines, a factorial experiment based on CRD was carried out at the agronomy lab of the Zanjan University Analysis of variance showed significant differencesfor all rooting traits:material transfering speed, germination percent, angle, diameter, fresh and dry weight, surface area, cumulative length, the length of t...
Although linkages of leaf and whole-plant traits to leaf lifespan have been rigorously investigated, there is a limited understanding of similar linkages of whole-plant and fine root traits to root lifespan. In comparisons across species, do suites of traits found in leaves also exist for roots, and can these traits be used to predict root lifespan? We observed the fine root lifespan of 12 temp...
A 74-year-old man was diagnosed with aortic root aneurysm and two-vessel coronary disease. Echocardiographic assessment revealed an enlarged sinus of Valsalva 60 mm in diameter with mild aortic regurgitation. Florida sleeve repair was performed using a vascular graft combined with coronary artery bypass grafting. The postoperative course was uncomplicated and follow-up echocardiographic evaluat...
background and aim . gingivitis is a reversible inflammatory reaction seen with various degrees in most individuals aged 17 to 22 years. the aim of this study was to compare the effects of two herbal extracts on streptococcus salivarius and streptococcus sanguis. materials and methods . aqueous alcoholic root extracts of malva sylvestris and salvadora persica were prepared and tested on pseudom...
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...
