background and aim: it is well - known that sex hormones regulate bone metabolism. sex steroids increase osteoblasts activities and affect growth, remodeling and bone homeostasis. the aim of this study was to examine the effects of sex hormones deficiency on craniofacial growth in rats. methods & materials: fifty, thirty–day–old wistar rats comprised the sample in this experimental study. 25 ma...

seven rice varieties (hassani, deilmani, sepidrod, shahpasand, saleh, neda, and irfaon215) along with their complete diallel progenies were grown in a randomized complete block design of three replications in the growing seasons of 2006 and 2007 and were evaluated for the quantitative traits of: number of days to flowering, flag leaf length, width and area, plant height, panicle length, extrusi...

background: st. john’s wort (hypericum perforatum l.) is an important medicinal plant that has been widely used for its antidepressant properties. objective: in this study morphological characteristics variation of populations of h. perforatum were investigated. methods: in this study, different morphological characteristics of 25 h. perforatum populations in iran’s natural habitats were evalua...

'Lovran Marron' is the only known traditional Croatian variety of the sweet chestnut. The objective of this study is to specify qualitative and quantitative morphological characteristics and to analyze the chemical composition of the 'Lovran Marron' fruits as well as to compare them to Marušnjak fruits (trees from the 'Lovran Marron' seed) and fruits from the local natural sweet chestnut popula...

background: the foramen magnum (fm) is an important landmark of the skull base and a transition zone between spine and skull as well as its close relationship to the brain and the spinal cord. so the fm has gained considerable interest due to its comparative anatomy, ontogeny, clinical, and animal breeding viewpoints. objectives: the aim of this study was to determine morphology and morphometry...

variability in morphological traits, phenolic content, and antioxidant activity of 15 populations of iranian ferula species collected from natural habitats in different regions of iran were investigated. total phenolic content (tpc) of fruit extracts varied from 12.77 to 120.72 mg tannic acid per 1g dry weight. total flavonoid of fruits extract varied from 5.45 mg quercetin per 1 g dry weight i...
