In this study the effect of Centella asiatica L. extract was studied against genotoxic doses of ethinylestradiol on human lymphocytes culture. The different doses of C. asiatica L. extract i.e. 1.075x10-4, 2.125x10-4 and 3.15x10-4 g/ml were treated separately with 5 μM of ethinylestradiol. Similar treatments were given with 10 μM of ethinylestradiol. The treatments result in a significant dose ...

Neuroblastoma is a childhood tumour with heterogeneous characteristics and children with metastatic disease often have a poor outcome. Here we describe the establishment of neuroblastoma patient-derived xenografts (PDXs) by orthotopic implantation of viably cryopreserved or fresh tumour explants of patients with high risk neuroblastoma into immunodeficient mice. In vivo tumour growth was monito...

Rice (Oryza sativa L.) is the most important crop all over the world. It is considered the main 19 food of 50% of the world population especially in Egypt. However, rice not only accumulates some of 20 heavy metals such as cadmium but also accumulate arsenate (As). Arsenic contamination in water and 21 food resulted in many implications for millions of people leading cancer. For that reason, th...
