We analyzed DNA damage, mitotic activity and polyploidization in Crepis capillaris callus cells during shortand long-term in vitro culture, and the influence of plant growth regulators on these processes. Changes in the concentration of growth regulators altered the stability of callus. The level of DNA damage was highly dependent on the growth regulator composition of the medium. Cytokinin at ...
Plant tissue culture refers to growing and multiplication of cells, tissues and organs of plants on defined solid or liquid media under aseptic and controlled environment. Micropropagation allows rapid production of high quality, disease-free and uniform planting material. The micropropagation of high quality planting materials of ornamentals, and forest and fruit trees has created new opportun...
in this thesis, a better reaction conditions for the synthesis of spirobarbiturates catalyzed by task-specific ionic liquid (2-hydroxy-n-(2-hydroxyethyl)-n,n-dimethylethanaminium formate), calcium hypochlorite ca(ocl)2 or n-bromosuccinimide (nbs) in the presence of water at room temperature by ultrasonic technique is provided. the design and synthesis of spirocycles is a challenging task becaus...

Introduction: Retinoblastoma is a malignant tumor in children. The goal of retinoblastoma treatment is to maintain vision and minimize side effects. In this study, the toxicity of the gold nanoparticle safety in vitro was investigated on an eye tumor of retinoblastoma under in vivo conditions. Materials and Methods: For the evaluation of the toxicity of gold nanoparticles using MTT test after 4...
