abstract persian walnut is one of the most important nut crops in iran. now the majority of orchards are seedling with a great diversity. for establishing uniform orchards and increasing the quantity and quality of yield, patch budding as the most suitable propagation methods, have still technical and practical problems in the country. in spite of high percent of primary success in patch buddin...
Prostate ductal development is initiated by androgen-dependent signals in fetal urogenital sinus (UGS) mesenchyme that stimulate prostatic bud formation in UGS epithelium. 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD, 5 microg/kg maternal dose) inhibited ventral and dorsolateral but not anterior prostatic budding. We sought to determine which stage of budding, specification or initiation, was inhi...
We have studied the expression of transforming growth factor beta-1 (TGF-beta 1) RNA during mouse tooth development, using in situ hybridization and experimental tissue recombinations. Analysis of the serial sections revealed the appearance of local expression of TGF-beta 1 RNA in the dental epithelium at bud-staged teeth (13-day embryos). Just before transition to the cap stage, TGF-beta 1 RNA...
Dental anomaly in number, size, and shape might occur during dental bud morphodifferentiation stage. Gemination and fusion are the most common anomalies. Gemination exhibits two joined crowns and usually a single root. This case report presents a geminated maxillary lateral incisor in a 15-year-old female admitted with symptoms of irreversible pulpitis and normal apical tissues. Clinical examin...
The effects of soil cadmium (Cd) contamination on Cd accumulation and distribution, growth and physiological responses of sunflower plants were investigated. Plants were subject to six levels of soil contamination (from 2.5 to 15 mg Cd kg/soil) with an untreated control, from the emergence of the cotyledon leaves until the harvest, when plants were at the flower bud stage. An overall increase o...
