eight accessions of thyme medicinal plant, belonging to iranian endemic thymus daënensis, t. eriocalyx, t. migricus and an unknown thymus spp species, were tested for karyotypic analysis, using squash technique and 2% (w/v) aceto-orcein staining method. chromosomal parameters examined were: short arm (s), long arm (l), total length of chromosome (tl), arm ratio (ar), r-value, total chromosome v...

Tendon tissue and the extracellular matrix of skeletal muscle respond to mechanical loading by increased collagen expression and synthesis. This response is likely a secondary effect of a mechanically induced expression of growth factors, including transforming growth factor-beta1 (TGF-beta1) and insulin-like growth factor-I (IGF-I). It is not known whether unloading of tendon tissue can reduce...

the inheritance of cold resistance was evaluated at the germination stage in crosses between seven rice genotypes as half diallel. analysis of variance indicated that there were highly significant differences among the genotypes, general combining ability (gca) and specific combining ability (sca) for percentage of reduction in radicle length (rl), percentage of reduction in plumule length (pl)...

The effect of nitrogen fertilization on root length (RL) distribution of winter wheat (Triticum aestivum L.) was investigated. The study was conducted in Prague-Ruzyne on clay loam Chernozemic soil in the years 1996–2003. Two (N0, N1) and three (N0, N1, N2) treatments, unfertilized (N0), fertilized with 100 kg (N1) and 200 kg N/ha (N2) were studied in 1996–2000 and 2001–2003, respectively. Nitr...

in order to study of yield, growth index and physiological traits in spring sugar beet genotypes with delayed planting date, a field experiment was carried out in chenaran in khorasan razavi province in the east of iran in 2008 cropping season. for this experiment a complete randomized block design with 4 replications and 6 treatments was used. the experimental treatments were six improved vari...

OBJECTIVES This study sought to identify risk factors for rapid growth of the ascending aorta in patients with bicuspid aortic valve (BAV) disease, taking into account its phenotypic variability. BACKGROUND Phenotypic heterogeneity of BAV-related aortopathy has recently been widely recognized. However, few studies have addressed the determinants of aortic growth so far, not distinguishing amo...

BACKGROUND AND AIMS Studies of the plasticity of functional root traits involved in resource acquisition have focused mainly on root length without considering such 'morphological components' as biomass allocation, specific root length, root fineness, and tissue density that affect root length. The plasticity of the above components in response to nitrate supply was studied in each root order o...

Supporting for updating XML documents has recently attracted interest. This paper presents a novel declarative XML update language, which is an extension of the XML-RL query language. We define XML-RL update syntax and a set of primitive update operations to fully evolve XML into universal data representation and sharing format.
