Background & Objective: Transformation of plasmid DNA into bacterial competent cells is a key technique for molecular cloning. Transformation can be achieved using either chemical or physical methods, e.g., electroporation. The rate of success in these methods depends on experience and attention to method’s details. Therefore, the higher the efficiency and quality of a transformation method, ...
BACKGROUND AND AIM: Oral leukoplakia (OL) is a common premalignant lesion. The possible benefits of specific interventions in preventing a malignant transformation of OL are not well understood. This review assesses different invasive treatment techniques for OL and evaluate the optimal treatment possibilities.METHODS: A Medline (PubMed) search was conducted and heterogeneity between the studie...
Abstract: A combination of a finite element method (FEM) algorithm with ANSYS codes and post image processing of NDT ultrasonic images along with laboratory cooling experiments and microstructural analysis provide a guideline to determine the optimum cooling rate for any grade of steel in which the highest productivity can be achieved without any degradation of the cast steel products. The sugg...
plant tissue culture techniques are used as basic requirement of common plant transformation systems. in most cases of plant transformation, a reproducible regeneration protocol is the limiting step due to long time lasting, specialized facilities and well experienced persons. furthermore, tissue culture procedures induce somaclonal variation among regenerated transgenic plants. therefore, rece...
